CC 2014-10-14_08.j. Approve Sewer System Management Plan p.RROyO O C,P INCORPORATED 9Z * JULY 10. 1911 C, `P. MEMORANDUM 41 F O FtN TO: CITY COUNCIL FROM: GEOFF ENGLISH, PUBLIC WORKS DIRECTOR-74,' BY: SHANE TAYLOR, PUBLIC WORKS SUPERVISOR — UTILITIES SUBJECT: CONSIDERATION TO APPROVE THE SEWER SYSTEM MANAGEMENT PLAN — REV.01 DATE: OCTOBER 14, 2014 RECOMMENDATION: Staff recommends the City Council approve and implement the completed Sewer System .Management Plan (SSMP-Rev.01) prepared in accordance with the State Water Resources Control Board (SWRCB) General Waste Discharge Requirements (GWDR) Order No. 2006-0003-DWQ. IMPACT ON FINANCIAL AND PERSONNEL RESOURCES: A total of $46,000 has been budgeted in the Sewer Fund as part of the ongoing work within FY 2014/15 budget. Approximately 80 staff hours will be required this fiscal year. to administer the Plan. New requirements imposed on public agencies through this State Order will require approximately 60 hours of additional work by City staff that is not funded. This new "un-funded mandate" will involve the preparation and implementation of procedures, process and documentation not previously required by the State Water Resources Control Board. BACKGROUND: On May 2, 2006, the SWRCB adopted Order No. 2006-0003-DWQ, entitled "Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (Discharge Order)." The Discharge Order adds new regulations in the State's effort to reduce Sanitary Sewer Overflows (SSOs). To comply with the Order, the City Council adopted the SSMP on 8/11/09. ANALYSIS OF ISSUES: To continue compliance with the Discharge Order, the City is required to complete'the Sewer System Management Plan (SSMP) 5-year update and recertification. The City's revised SSMP has been prepared per the (SSS-WDR) and includes significant program changes. The SSMP documents the City's Sanitary Sewer System, defines the City's Item 8.j. - Page 1 CITY COUNCIL CONSIDERATION OF APPROVAL OF THE SEWER SYSTEM MANAGEMENT PLAN OCTOBER 14, 2014 PAGE 2 goals for improving its sewer system infrastructure, and establishes an implementation plan and schedule for achieving these goals. There are eleven (11) components of the Plan: 1. Goals; 2. Organization; 3. Legal Authority; 4. Operation and Maintenance; 5. Design and Performance Standards; 6. Overflow Emergency Response Plan; 7. Fats, Oils and Grease (FOG) Control Program; 8. System Evaluation and Capacity Assurance Plan; 9. Monitoring, Measurement, and Program Modification; 10. Sewer System Management Plan Audits; 11. Communication Plan. The City has been operating the. sewer system within the guidelines of the current SSMP. The revised SSMP meets the Discharge Order requirements. The SSMP will help prevent sanitary sewer overflows by proactively implementing system-wide operation, maintenance, and management. ALTERNATIVES: The following alternatives are provided for the Council's consideration: - Approve staff recommendations; approval of the SSMP allows the City of Arroyo Grande to meet the Statewide General WDR and the Discharge Order; - Do not approve staff recommendations; failure to approve will result in non- compliance with the Statewide General WDR and the Discharge Order; - Modify the SSMP and approve staff's recommendation; or - Provide direction to staff. ADVANTAGES: It is advantageous to take action under the staff recommendation. Approval of the SSMP ensures compliance in meeting the State certification as determined by the Statewide General WDR Order No. 2006-0003-DWQ. DISADVANTAGES: No disadvantages have been identified other than expending $46,000 to administer the SSMP. ENVIRONMENTAL REVIEW: In accordance with Section 15278(b)(5) of the California Environmental Quality Act (CEQA) Guidelines, this Council action does not constitute a "project" and is not subject to the requirements of CEQA.

Introduction Background The City of Arroyo Grande initially prepared a Wastewater Collection System Management Plan in 2006 to comply with requirements of the Central Coast Regional Water Quality Control Board (RWQCB) pursuant to Section 13267 of the California Water Code. The City of Arroyo Grande also complied with RWQCB Sanitary Sewer Overflow (SSO) reporting requirements issued in November 2004 through its enrollment in the reporting program at that time. On May 2, 2006, the State Water Resource Control Board (SWRCB) adopted Order No. 2006- 0003 a new General Waste Discharge Requirement (GWDR) that requires all public wastewater collection system agencies in California with greater than one mile of sewer collection system to develop and implement a Sewer System Management Plan (SSMP). The Order also requires that cities enroll in and begin the reporting of SSOs using the California Integrated Water Quality System (CIWQS), an electronic reporting system. On February 20, 2008, the State Board adopted Order No. WQ 2008-0002 EXEC which amended the monitoring and reporting requirements for the General Statewide Order. On July 30, 2013, the State Board adopted Order No. WQ 2013-0058-EXEC that further amended the monitoring and reporting requirements. This SSMP is being updated pursuant to Order No. 2006-0003, Provision D.14. The organization of this document is consistent with the General Statewide Order. The SSMP includes eleven elements, as follows: 1. Goals 2. Organization 3. Legal Authority 4. Sewer System Management Plan Operations and Maintenance 5. Design and Performance Standards 6. Overflow Emergency Response Plan 7. Fats, Oils & Grease Control (FOG) Program 8. System Evaluation and Capacity Assurance Plan 9. Monitoring, Measurement and Plan Modifications 10. Sewer System Management Plan Program Audits 11. Communication Program System Overview The City of Arroyo Grande is a public agency providing sewage collection services to residential and commercial/institutional establishments. The City maintains 70 miles of sewer main servicing approximately 5,700 residences and 400 commercial/institutional establishments. The City owns and maintains its sewer collection system. The system is connected to a trunk sewer system and wastewater treatment plant (WWTP) that is owned and operated by the South San Luis Obispo County Sanitation District (SSLOCSD). The City of Arroyo Grande is a member agency of the SSLOCSD along with the Oceano Community Services District and the City of Grover Beach. City of Arroyo Grande SSMP Page Intro-1 NMI Sewer System Management Plan—Revision 01 Introduction The City of Arroyo Grande is the largest discharger into the SSLOCSD. The City encompasses 5.45 square miles and has a population of approximately 17,100 people, located by way of latitude 35 degrees 7' 15" North and longitude of 120 degrees 35' 12" West. Figure A: Arial Map of City of Arroyo Grande o � / J r u n r 1 a 1, i /r a 9 t - 9 V *� f The City of Arroyo Grande (City) is governed by a five member council, with each council member serving a four year term. The City Council is an elected body that makes decisions that are in the best interest of the city and its residents. The City Council establishes City policy, setting goals and objectives, approves the annual budget, approves expenditures and performs other related functions. The names of current council members are provided in Appendix 2A. The City is responsible for operation and maintenance of the wastewater collection and transport systems up to the point of discharge into the SSLOCSD trunk system. The City takes this responsibility seriously and is dedicated to protecting the environment to the greatest degree possible. The City insures the collection system is protected and utilized properly. The accountability includes preventing overflows, which may include restricting or prohibiting the volume, type, or concentration of wastes added to the system. The primary requirement of the GWDR is the preparation and implementation of a SSMP. By preparing and implementing the procedures in the plan, the potential of sewer spills should decrease. A large portion of the requirements are currently in practice by the City due to years of taking a proactive approach to sewer system management. City of Arroyo Grande SSMP Page Intro-2 NMI lm� Sewer System Management Plan—Revision 01 Element 1 —Goals Element 1 - Goals This SSMP element identifies goals the City of Arroyo Grande has established for the management and maintenance of the sewer system and discusses the role of the SSMP in supporting these goals. These goals provide focus for the City of Arroyo Grande Staff to continue high-quality work and to implement improvements in the management of the wastewater collection system. Element 1: Goals Appendix Supporting information for Element 1 is included in Appendix 1 which contains the following documents: • SWRCB Waste Discharge Requirement Order No. 2006-0003-DWQ • SWRCB Order No. WQ 2008-0002-EXEC • SWRCB Order No. WQ 2013-0058-EXEC 1.1 Regulatory Requirements The summarized requirements for the Goals element of the SSMP are as follows: The Collection system agency must develop goals to properly manage, operate and maintain all parts of its wastewater collection system in order to reduce and prevent SSOs, as well as to mitigate any SSOs that occur. The goals should also address the provisions of adequate capacity to convey peak wastewater flows. 1.2 Goals Discussion The City of Arroyo Grande seeks to provide a dependable and properly maintained system for wastewater collection for its constituents by meeting the following goals: • Be available and responsive to the needs of the public, and work cooperatively with local, state and federal agencies to reduce, mitigate, properly report, and respond to SSOs. • Properly manage and maintain the City of Arroyo Grande public sewer system lines to minimize SSOs. • Identify, prioritize, and continuously renew and replace sewer system lines to maintain reliability. • Implement regular, proactive maintenance of the sewer system to remove roots, debris, sand, and Fats, Oils and Grease (FOG) in areas prone to blockages that may cause SSOs or sewer backups. • Coordinate with South San Luis Obispo County Sanitation District (SSLOCSD) to manage and implement the SSLOCSD Pretreatment Program to protect the treatment plant and the environment.

All federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California are required to comply with the terms of this Order. Such entities are hereinafter referred to as "Enrollees". 2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of domestic wastewater, as well as industrial and commercial wastewater, depending on the pattern of land uses in the area served by the sanitary sewer system. SSOs often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. SSOs may cause a public nuisance, particularly when raw untreated wastewater is discharged to areas with high public exposure, such as streets or surface waters used for drinking, fishing, or body contact recreation. SSOs may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters. 3. Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state. There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO. A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs. 4. Major causes of SSOs include: grease blockages, root blockages, sewer line flood damage, manhole structure failures, vandalism, pump station mechanical failures, power outages, excessive storm or ground water inflow/infiltration, debris blockages, sanitary sewer system age and construction material failures, lack of proper operation and maintenance, insufficient capacity and contractor- caused damages. Many SSOs are preventable with adequate and appropriate facilities, source control measures and operation and maintenance of the sanitary sewer system. State Water Resources Control Board Order No. 2006-0003-DWQ Page 2 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 SEWER SYSTEM MANAGEMENT PLANS 5. To facilitate proper funding and management of sanitary sewer systems, each Enrollee must develop and implement a system-specific Sewer System Management Plan (SSMP). To be effective, SSMPs must include provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Additionally, an SSMP must contain a spill response plan that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions. 6. Many local public agencies in California have already developed SSMPs and implemented measures to reduce SSOs. These entities can build upon their existing efforts to establish a comprehensive SSMP consistent with this Order. Others, however, still require technical assistance and, in some cases, funding to improve sanitary sewer system operation and maintenance in order to reduce SSOs. 7. SSMP certification by technically qualified and experienced persons can provide a useful and cost-effective means for ensuring that SSMPs are developed and implemented appropriately. 8. It is the State Water Board's intent to gather additional information on the causes and sources of SSOs to augment existing information and to determine the full extent of SSOs and consequent public health and/or environmental impacts occurring in the State. 9. Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by this Order and the attached Monitoring and Reporting Program No. 2006-0003-DWQ, are necessary to assure compliance with these waste discharge requirements (WDRs). 10.Information regarding SSOs must be provided to Regional Water Boards and other regulatory agencies in a timely manner and be made available to the public in a complete, concise, and timely fashion. 11.Some Regional Water Boards have issued WDRs or WDRs that serve as National Pollution Discharge Elimination System (NPDES) permits to sanitary sewer system owners/operators within their jurisdictions. This Order establishes minimum requirements to prevent SSOs. Although it is the State Water Board's intent that this Order be the primary regulatory mechanism for sanitary sewer systems statewide, Regional Water Boards may issue more stringent or more State Water Resources Control Board Order No. 2006-0003-DWQ Page 3 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of a Regional Water Board's WDRs for a system subject to this Order, the Regional Water Board shall coordinate its requirements with stated requirements within this Order, to identify requirements that are more stringent, to remove requirements that are less stringent than this Order, and to provide consistency in reporting. REGULATORY CONSIDERATIONS 12. California Water Code section 13263 provides that the State Water Board may prescribe general WDRs for a category of discharges if the State Water Board finds or determines that: • The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general discharge requirements than individual discharge requirements. This Order establishes requirements for a class of operations, facilities, and discharges that are similar throughout the state. 13.The issuance of general WDRs to the Enrollees will: a) Reduce the administrative burden of issuing individual WDRs to each Enrollee; b) Provide for a unified statewide approach for the reporting and database tracking of SSOs; C) Establish consistent and uniform requirements for SSMP development and implementation; d) Provide statewide consistency in reporting; and e) Facilitate consistent enforcement for violations. 14.The beneficial uses of surface waters that can be impaired by SSOs include, but are not limited to, aquatic life, drinking water supply, body contact and non- contact recreation, and aesthetics. The beneficial uses of ground water that can be impaired include, but are not limited to, drinking water and agricultural supply. Surface and ground waters throughout the state support these uses to varying degrees. 15.The implementation of requirements set forth in this Order will ensure the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each region and take into account the environmental characteristics of hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect State Water Resources Control Board Order No. 2006-0003-DWQ Page 4 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 water quality in the area, costs associated with compliance with these requirements, the need for developing housing within California, and the need to develop and use recycled water. 16.The Federal Clean Water Act largely prohibits any discharge of pollutants from a point source to waters of the United States except as authorized under an NPDES permit. In general, any point source discharge of sewage effluent to waters of the United States must comply with technology-based, secondary treatment standards, at a minimum, and any more stringent requirements necessary to meet applicable water quality standards and other requirements. Hence, the unpermitted discharge of wastewater from a sanitary sewer system to waters of the United States is illegal under the Clean Water Act. In addition, many Basin Plans adopted by the Regional Water Boards contain discharge prohibitions that apply to the discharge of untreated or partially treated wastewater. Finally, the California Water Code generally prohibits the discharge of waste to land prior to the filing of any required report of waste discharge and the subsequent issuance of either WDRs or a waiver of WDRs. 17.California Water Code section 13263 requires a water board to, after any necessary hearing, prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge. The requirements shall, among other things, take into consideration the need to prevent nuisance. 18.California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements: a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property. b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes. 19.This Order is consistent with State Water Board Resolution No. 68-16 (Statement of Policy with Respect to Maintaining High Quality of Waters in California) in that the Order imposes conditions to prevent impacts to water quality, does not allow the degradation of water quality, will not unreasonably affect beneficial uses of water, and will not result in water quality less than prescribed in State Water Board or Regional Water Board plans and policies. 20.The action to adopt this General Order is exempt from the California Environmental Quality Act (Public Resources Code §21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment. (Cal. Code Regs., tit. 14, §15308). In addition, the action to adopt State Water Resources Control Board Order No. 2006-0003-DWQ Page 5 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, §15301 to the extent that it applies to existing sanitary sewer collection systems that constitute "existing facilities" as that term is used in Section 15301, and §15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity. 21.The Fact Sheet, which is incorporated by reference in the Order, contains supplemental information that was also considered in establishing these requirements. 22.The State Water Board has notified all affected public agencies and all known interested persons of the intent to prescribe general WDRs that require Enrollees to develop SSMPs and to report all SSOs. 23.The State Water Board conducted a public hearing on February 8, 2006, to receive oral and written comments on the draft order. The State Water Board received and considered, at its May 2, 2006, meeting, additional public comments on substantial changes made to the proposed general WDRs following the February 8, 2006, public hearing. The State Water Board has considered all comments pertaining to the proposed general WDRs. IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the Enrollees, their agents, successors, and assigns, in order to meet the provisions contained in Division 7 of the California Water Code and regulations adopted hereunder, shall comply with the following: A. DEFINITIONS 1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include- (i) Overflows or releases of untreated or partially treated wastewater that reach waters of the United States; (ii) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and (iii) Wastewater backups into buildings and on private property that are caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system. 2. Sanitary sewer system —Any system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to the publicly owned treatment facility. Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, etc.) are considered to be part of the sanitary sewer system, and discharges into these temporary storage facilities are not considered to be SSOs. State Water Resources Control Board Order No. 2006-0003-DWQ Page 6 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 For purposes of this Order, sanitary sewer systems include only those systems owned by public agencies that are comprised of more than one mile of pipes or sewer lines. 3.

SSO Reporting System — Online spill reporting system that is hosted, controlled, and maintained by the State Water Board. The web address for this site is http-Hciwgs.waterboards.ca.gov. This online database is maintained on a secure site and is controlled by unique usernames and passwords. 5. Untreated or partially treated wastewater—Any volume of waste discharged from the sanitary sewer system upstream of a wastewater treatment plant headworks. 6. Satellite collection system — The portion, if any, of a sanitary sewer system owned or operated by a different public agency than the agency that owns and operates the wastewater treatment facility to which the sanitary sewer system is tributary. 7. Nuisance - California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements: a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property. b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes. B. APPLICATION REQUIREMENTS 1. Deadlines for Application —All public agencies that currently own or operate sanitary sewer systems within the State of California must apply for coverage under the general WDRs within six (6) months of the date of adoption of the general WDRs. Additionally, public agencies that acquire or assume responsibility for operating sanitary sewer systems after the date of adoption of this Order must apply for coverage under the general WDRs at least three (3) months prior to operation of those facilities. 2. Applications under the general WDRs — In order to apply for coverage pursuant to the general WDRs, a legally authorized representative for each agency must submit a complete application package. Within sixty (60) days of adoption of the general WDRs, State Water Board staff will send specific instructions on how to State Water Resources Control Board Order No. 2006-0003-DWQ Page 7 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 apply for coverage under the general WDRs to all known public agencies that own sanitary sewer systems. Agencies that do not receive notice may obtain applications and instructions online on the Water Board's website. 3. Coverage under the general WDRs — Permit coverage will be in effect once a complete application package has been submitted and approved by the State Water Board's Division of Water Quality. C. PROHIBITIONS 1. Any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States is prohibited. 2. Any SSO that results in a discharge of untreated or partially treated wastewater that creates a nuisance as defined in California Water Code Section 13050(m) is prohibited. D. PROVISIONS 1. The Enrollee must comply with all conditions of this Order. Any noncompliance with this Order constitutes a violation of the California Water Code and is grounds for enforcement action. 2. It is the intent of the State Water Board that sanitary sewer systems be regulated in a manner consistent with the general WDRs. Nothing in the general WDRs shall be- (i) Interpreted or applied in a manner inconsistent with the Federal Clean Water Act, or supersede a more specific or more stringent state or federal requirement in an existing permit, regulation, or administrative/judicial order or Consent Decree; (ii) Interpreted or applied to authorize an SSO that is illegal under either the Clean Water Act, an applicable Basin Plan prohibition or water quality standard, or the California Water Code; (iii) Interpreted or applied to prohibit a Regional Water Board from issuing an individual NPDES permit or WDR, superseding this general WDR, for a sanitary sewer system, authorized under the Clean Water Act or California Water Code; or (iv) Interpreted or applied to supersede any more specific or more stringent WDRs or enforcement order issued by a Regional Water Board. 3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate the impacts of an SSO. 4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent untreated or partially treated wastewater from discharging from storm drains into State Water Resources Control Board Order No. 2006-0003-DWQ Page 8 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 flood control channels or waters of the United States by blocking the storm drainage system and by removing the wastewater from the storm drains. 5. All SSOs must be reported in accordance with Section G of the general WDRs. 6. In any enforcement action, the State and/or Regional Water Boards will consider the appropriate factors under the duly adopted State Water Board Enforcement Policy. And, consistent with the Enforcement Policy, the State and/or Regional Water Boards must consider the Enrollee's efforts to contain, control, and mitigate SSOs when considering the California Water Code Section 13327 factors. In assessing these factors, the State and/or Regional Water Boards will also consider whether: (i) The Enrollee has complied with the requirements of this Order, including requirements for reporting and developing and implementing a SSMP; (ii) The Enrollee can identify the cause or likely cause of the discharge event; (iii)There were no feasible alternatives to the discharge, such as temporary storage or retention of untreated wastewater, reduction of inflow and infiltration, use of adequate backup equipment, collecting and hauling of untreated wastewater to a treatment facility, or an increase in the capacity of the system as necessary to contain the design storm event identified in the SSMP. It is inappropriate to consider the lack of feasible alternatives, if the Enrollee does not implement a periodic or continuing process to identify and correct problems. (iv)The discharge was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Enrollee; (v) The discharge could have been prevented by the exercise of reasonable control described in a certified SSMP for • Proper management, operation and maintenance; • Adequate treatment facilities, sanitary sewer system facilities, and/or components with an appropriate design capacity, to reasonably prevent SSOs (e.g., adequately enlarging treatment or collection facilities to accommodate growth, infiltration and inflow (I/I), etc.); • Preventive maintenance (including cleaning and fats, oils, and grease (FOG) control); • Installation of adequate backup equipment; and • Inflow and infiltration prevention and control to the extent practicable. (vi)The sanitary sewer system design capacity is appropriate to reasonably prevent SSOs. State Water Resources Control Board Order No. 2006-0003-DWQ Page 9 of 20 Statewide General WDR For Wastewater Collection Agencies 512106 (vii) The Enrollee took all reasonable steps to stop and mitigate the impact of the discharge as soon as possible. 7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps and necessary remedial actions to 1) control or limit the volume of untreated or partially treated wastewater discharged, 2) terminate the discharge, and 3) recover as much of the wastewater discharged as possible for proper disposal, including any wash down water. The Enrollee shall implement all remedial actions to the extent they may be applicable to the discharge and not inconsistent with an emergency response plan, including the following- (i) Interception and rerouting of untreated or partially treated wastewater flows around the wastewater line failure; (ii) Vacuum truck recovery of sanitary sewer overflows and wash down water; (iii) Cleanup of debris at the overflow site; (iv) System modifications to prevent another SSO at the same location; (v) Adequate sampling to determine the nature and impact of the release; and (vi) Adequate public notification to protect the public from exposure to the SSO. 8. The Enrollee shall properly, manage, operate, and maintain all parts of the sanitary sewer system owned or operated by the Enrollee, and shall ensure that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities. 9. The Enrollee shall allocate adequate resources for the operation, maintenance, and repair of its sanitary sewer system, by establishing a proper rate structure, accounting mechanisms, and auditing procedures to ensure an adequate measure of revenues and expenditures. These procedures must be in compliance with applicable laws and regulations and comply with generally acceptable accounting practices. 10.The Enrollee shall provide adequate capacity to convey base flows and peak flows, including flows related to wet weather events. Capacity shall meet or exceed the design criteria as defined in the Enrollee's System Evaluation and Capacity Assurance Plan for all parts of the sanitary sewer system owned or operated by the Enrollee. 11.The Enrollee shall develop and implement a written Sewer System Management Plan (SSMP) and make it available to the State and/or Regional Water Board upon request. A copy of this document must be publicly available at the Enrollee's office and/or available on the Internet. This SSMP must be approved by the Enrollee's governing board at a public meeting.

CERTIFICATION The undersigned Clerk to the Board does hereby certify that the foregoing is a full, true, and correct copy of a resolution duly and regularly adopted at a meeting of the State Water Board held on May 2, 2006. Song Her Clerk to the Board Appendix 1-2: STATE OF CALIFORNIA STATE WATER RESOURCES CONTROL BOARD ORDER NO. WO 2008-0002-EXEC ADOPTING AMENDED MONITORING AND REPORTING REQUIREMENTS FOR STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR SANITARY SEWER SYSTEMS The State of California, Water Resources Control Board (State Water Board)finds: 1. The State Water Board is authorized to prescribe statewide general waste discharge requirements for categories of discharges that involve the same or similar operations and the same of similar types of waste pursuant to Water Code 13263, subdivision (i). 2. The State Water Board on May 2, 2006, adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Order No. 2006-0003-DWQ, pursuant to that authority. 3. The State Water Board on May 2, 2006, adopted Monitoring and Reporting. Requirements to implement.the General Waste Discharge Requirements for Sanitary Sewer Systems. 4. State Water Board Order No. 2006-0003-DWQ, paragraph G.2., and the Monitoring and Reporting Requirements, both provide that the Executive Director may modify the terms of the Monitoring and Reporting Requirements at any time. 6. The time allowed in those Monitoring and Reporting Requirements for the filing of the initial report of an overflow is too long to adequately protect the public health and safety or the beneficial uses of the waters of the state when there is a sewage collection system spill. An additional notification requirement is necessary and appropriate to ensure the Office of Emergency Services, local public health officials, and the applicable regional water quality control board are apprised of a spill that reaches a drainage channel or surface water. 6. Further, the burden of providing a notification as soon as possible is de minimis and will allow response agencies to take action as soon as possible to protect public health and safety and beneficial uses of the waters of the state. IT IS HEREBY ORDERED THAT: Pursuant to the authority delegated by Resolution No. 2002-0104 and Order No. 2006-0003- DWQ, the Monitoring and Reporting Requirements for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems No. 2006-0003-DWQ is hereby amended as shown in Attachment A, with new text indicated by double-underline.

This Chapter of the Municipal Code is available to the public on the internet at: http://municipalcodes.Iexisnexis.com/codes/arroyo/. Element 3: Legal Authority Appendix Supporting information for Element 3 is included in Appendix 3 which contains the following document: • City of Arroyo Grande Municipal Code Chapter 13.12 3.1 Regulatory Requirements The City will demonstrate, through its sewer codes, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to: 1. Prevent illicit discharges into its sanitary sewer system (examples may include Inflow& Infiltration (1/1), storm water, chemical dumping, unauthorized debris and cut roots, etc.); 2. Require that sewers and connections be properly designed and constructed; 3. Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency, and 4. Limit the discharge of Fats, Oils, and Grease (FOG) and other debris that may cause blockages. 3.2 Inspections and Maintenance In an effort to control infiltration and inflow the City maintains and inspects portions of the sewer system. All Staff conducting inspections and maintenance to the sewer system are trained, either through a formal or in-house training program. The work of all contractors performing work on the sewer system are monitored, reviewed and inspected by the Maintenance Services Staff. Specifically, the sections of the City's Municipal Code to prevent illicit discharges into the sewer system including 1/1 from laterals, storm water, unauthorized debris, etc. can be found in: ■ Chapter 13.12 Sewer Service System Section 13.12.400 — Prohibited discharges Section 13.12.410 —Commercial and industrial discharges Section 13.12.420 — Private Systems - Discharges The City also refers to the following ordinance: ■ 1994-1 SSLOCSD Pretreatment Ordinance and Requirements The City is a satellite wastewater collection system which discharges into the South San Luis Obispo County Sanitation District's (SSLOCSD) trunk line. In addition, the City participates in an active FOG Control and Inspection Program (FOG Program). As part of the FOG Program, the City authorizes and provides funding for City of Arroyo Grande SSMP Page 3-1 Sewer System Management Plan—Revision 01 Element 3—Legal Authority Environmental Compliance Inspectors to inspect Food Service Establishments (FSEs) and educate owners regarding Best Management Practices (BMPs) for FSEs. 3.3 Design and Construction The City's Municipal Code provides the Legal Authority to require the proper design and construction of the City's sewer system. Standards concerning design and construction ensure the sewer lines and connections are properly designed and constructed. The purpose of the Standards and Specifications is to provide minimum standards for the design, kinds and uses of materials, and the preparation of plans for construction, repair, or alteration of City sewer and water facilities. The City's standard plans and specifications can be found on the City's website. ■ Chapter 13.12 Sewer Service System Section 13.12.110 – Groups of houses of buildings on one lot–Connections to main sewers Section 13.12.120 –Sewer connections--Applications Section 13.12.130 – Private systems—Construction—Inspections Section 13.12.140 –Approval – Required Section 13.12.150 –Approval - Process Section 13.12.270 – Inspection required Section 13.12.370 –Sewer pumps– Backflow valves The sections, from the Municipal Code, above address the standards expected by the City for conducting repairs or new construction related to the sewer system. In particular, the City requires the use of the uniform plumbing code and permits be obtained prior to construction. All work must be completed based upon the uniform plumbing code and any alterations to this must be approved by the Director. If it is ever determined that the City's adopted Standards and Specifications are insufficient the standards and specifications used will be from "Standard Specifications for Public Works Construction" known as the "Green Book". 3.4 Ensure Access to Privately Owned Portions of the Lateral The City prides itself on its relationship with local residents. The City's primary goal in instances where access is requested is to determine if Sanitary Sewer Overflows are likely to occur or if damage to the treatment plant or sewer lines is probable, this helps protect the public and environmental health of the City. ■ Chapter 13.12 Sewer Service System of the City's Municipal Code Section 13.12.270 – Inspection required Section 13.12.500 – Right of entry The City's current Municipal Code permits City representatives to enter premises for inspection, sampling and testing. 3.5 FOG Control The City has developed a FOG Control and Inspection Program (FOG Program). The City uses the SSLOCSDs FOG Ordinance. The SSLOCSD FOG Ordinance and the City's FOG Program work in conjunction to include regulations governing the sewer system pertaining to FOG City of Arroyo Grande SSMP Page 3-2 Sewer System Management Plan—Revision 01 Element 3—Legal Authority discharges. The Ordinances along with the Municipal Code contain the regulations allowing the implementation of the FOG Program. The Sections governing this are as follows: ■ Chapter 13.12 Sewer Service System ■ Chapter 13.12.400 Prohibited Discharges ■ 1994-1 SSLOCSD Pretreatment Ordinance ■ 2008-01 SSLOCSD FOG Ordinance See Element 7 for detailed information pertaining to the FOG Program. 3.6 Enforce Violations of its Sewer Ordinance It is essential to protect the City from chronic illegal discharge violations or manipulations of the sewer system. In the event that a person fails to comply with the current regulations, violations will be issued. The right to do so is found in The City Municipal Code under: ■ Chapter 13.12 Sewer Service System • Sections 13.12.470 -13.12.490 allows the City to request the resident to pay overdue bills. • Chapter 1.16 – Penalty Provisions • Chapter 9.12 – Nuisances • SSLOCSD Resolution No. 2011-295 can be utilized to enforce violations of the SSLOCSD FOG Ordinance 3.7 Sewer Use Fees Sewer fees are periodically reviewed for proper fee structure and applicability. This is further discussed in the City Municipal Code under: ■ Chapter 13.12 Sewer Service System • Section 13.12-190 –Connections—Fees—Capacity • Section 13.12.210 Connections—Fees—Disposition • Section 13.12.220 Connections—Fees—Exceptions • Section 13.12.230 Charges for extraordinary services • Section 13.12.240 Connections—Fees—Credits Fees are reviewed and adopted by City Council periodically to determine if the current rates reflect the proper rate pricing.

(Prior code § 6-6.1201) City of Arroyo Grande SSMP ffid I'M 41'f,''40"A" Sewer System Management Plan—Revision 01 Element 4—Sewer System Management Plan Operations and Maintenance Element 4 - Sewer System Management Plan Operations and Maintenance Operation and Maintenance of a sewer system extends beyond that of the Operations Staff. An efficient system involves the joint responsibility of agency engineers, management, field crews and the general public. The field crews can only function on the basis of available resources provided to them. It is the City's responsibility to make sure that the sanitary sewer collection system is kept in good working condition. To accomplish this, the City requires that the system be regularly maintained, so that the wastewater enters the treatment plant in an efficient way. As Operations Staff perform regular maintenance, they acquire practical experience regarding the operation of the sewer system making them an essential component for sewer system efficiency. Element 4: Operations and Maintenance Appendix Supporting information for Element 4 is included in Appendix 4 which contains the following documents: • Sewer System and Stormdrain Atlas • Capital Improvement Plan • Sanitary Sewer Cleaning Program Description & Schedule • Sanitary Sewer Cleaning Map (Example): Trouble Spots & Root Treatment Sheets • Critical Parts and Equipment List • Maintenance Work Order Form • Manhole Inspection Form • Service Request Form • City Standard Operating Procedure: Vactor PW 51 • Wastewater Master Plan 2012 • Draft Revenue Rate Study 4.1 Regulatory Requirements The SSMP must include those elements listed below that are appropriate and applicable to the Enrollee's system: a. Each wastewater collection system agency shall maintain up-to-date maps of its wastewater collection system facilities, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water pumping and piping facilities. b. Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventive Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders. City of Arroyo Grande SSMP Page 4-1 Sewer System Management Plan—Revision 01 Element 4—Sewer System Management Plan Operations and Maintenance C. Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and system for ranking the conditions of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementation of the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan. d. Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained. e. Provide equipment and replacement part inventories, including identification of critical replacement parts. 4.2 Collection System Map The City of Arroyo Grande maintains a collection system map that outlines the following features: location of the sewer lines, manholes, cleanouts, pipe sizes and pipe materials, and the direction of flow. Pump stations and other special structures are also identified. The City also maintains a Stormdrain System Map for use in the event of a SSO so that staff may locate stormwater inlets and outlets that have the potential to impact surface waters. (See Collection System Atlas—Appendix 4). A Stormwater Atlas is maintained at the City Public Works Department and a general overview of the system can be found in the City's Stormwater Management Plan on the City Website at: LttL,Ilwww.arrovoclrande.oLgIdocu mentcenter/view/312 As-built plans and construction drawings are also maintained as the collection system is improved and new systems are added or altered. As-built drawings are required by the City as a condition of construction. 4.3 Preventative Operations & Maintenance The City educates its Staff to think of maintenance in two ways: preventive and corrective. Corrective maintenance -This can be an actual collapse of an existing sewer; stoppage due to roots, FOG, or other foreign materials; inflow or infiltration; or pump failure. These conditions require immediate action to correct the problem and are further discussed in Element 6— Overflow Emergency Response. Additionally, the City maintains a Service Request Form to assist staff in responding to regular and emergency requests for corrective maintenance. A copy of this form is found in Appendix 4. Preventive maintenance—This involves inspection of the sewer system and analysis of existing data to identify trouble areas. Inspection and analysis provides guidance in determining the type, degree, and frequency of preventive maintenance required. The City currently maintains a Utilities Calendar that is used to schedule the following preventative maintenance activities: • Annual Sewer Main Cleaning • Problem Area Sewer Main Cleaning (High Maintenance Areas) • Lift Station Cleaning & Maintenance • Manhole Maintenance City of Arroyo Grande SSMP Page 4-2 Sewer System Management Plan—Revision 01 Element 4—Sewer System Management Plan Operations and Maintenance o Air/Vacuum Valve Maintenance The City updates this calendar annually. A copy of this Calendar can be found in Appendix 4. The objectives of both are to improve service, reduce emergency occurrences, and to minimize the cost of the preventive maintenance program. In general, the greater the amount of preventive maintenance performed, the less the amount of corrective maintenance that will be required. However, there should be a reasonable balance between the cost of preventive maintenance and a corresponding benefit. 4.3a Pipeline Maintenance The City of Arroyo Grande has developed a year-round pipeline maintenance program with an emphasis on preventive maintenance, especially in historical trouble areas which are checked at more frequent intervals. The system is videoed in suspected trouble areas on an as needed basis. The City sets a goal to clean and flush the entire system annually. Based on cleaning, flow analysis and video, the city determines which area of the pipeline system would benefit the most by rehabilitation or replacement. Quarterly cleanings are performed at historical problem areas based (trouble spots) on field crew experience. The city also participates in an active FOG Program and Root treatment program. A n example of City sewer system trouble spots and root treatment sheets can be found in Appendix 4. 4.3b Manholes The City of Arroyo Grande uses visual manhole inspections, as part of day to day maintenance. Visual inspections are an inexpensive and quick method of detecting inflow/ infiltration sources, the general structural condition of the manhole, and the accuracy of previous system drawings. Formal manhole inspections are also conducted when staff observes potential problems during routine sewer line cleaning. A copy of the form used to report on manhole inspections is located in Appendix 4. Visual and video manhole inspections are used to determine the following: Exact location of the manhole; • Condition of cover and frame (defects that may allow inflow); • Is the cover subject to ponding or surface run off; • Potential area that drains to any defects; • Condition of benching, risers, grade rings and collar; and • Condition of sewer pipes. Manhole repairs are required to correct structural deficiencies, effects of corrosion on the internal surface, and to eliminate the inflow of surface or groundwater. The City of Arroyo Grande continues to install manhole inflow covers to minimize potential infiltration. 4.3c Lift Station Maintenance The City of Arroyo Grande maintains five (5) lift stations. Duplication of equipment and functions provides the flexibility necessary for continued operation during individual shutdowns due to scheduled maintenance or emergencies. Weekly inspections are performed on the lift stations that include the, electrical equipment, instrumentation, wet well condition, venting and housekeeping. Weekly lift station and wet well inspections are performed by field crews. Lift Station wet wells are cleaned quarterly. Staff follows the City's Facilities Inspection Program Guidelines when conducting weekly lift station inspections. A copy of this program is on file at the City's Public Works office. This program is planned to be updated into the City's Standard Operating Procedures for Operations and Maintenance Activities by the end of 2015. City of Arroyo Grande SSMP Page 4-3 Sewer System Management Plan—Revision 01 Element 4—Sewer System Management Plan Operations and Maintenance 4.3d Investigation (Complaints) The service request form is used to record complaints from the public or from another governmental agency. This report becomes a permanent record and is subject to review at a later time. The Operations Staff ensures all entries they are required to make are complete and accurate. The City makes every effort to respond immediately to all sewer-related complaints followed by prompt correction of the defective condition. (A sample Work Order is provided at the end of this section in Appendix 4). 4.3e Maintenance Records The City uses a paper based Work Order system to keep records of preventive maintenance and repair service. (See the sample Work Order provided at the end of this section in Appendix 4.) The Work Orders allow the City to maintain records concerning a location, reason for the work, materials used, who the crew leader was and the amount of time it took to complete the work. The City is currently in the process of selecting a Computerized Maintenance Management System (CMMS) to track and schedule Preventative Maintenance. This system is planned to be in place by the end of 2015. A description and examples demonstrating the selected CMMS will be included in the SSMP once it is implemented. 4.4 Rehabilitation and Replacement Program The City utilizes a number of measures to keep the existing sewer collection system functional. These range from local rehabilitation to complete replacement of the sewer section. There are several repair methods available. The choice of method or a combination of methods depends on the physical condition of the sewer system components (i.e., pipeline sections, manholes, and service connections) and the nature and magnitude of the problem. If the problem does not involve the structural integrity of the system's components or the need to increase the capacity of the existing system, rehabilitation can be an effective way of restoring the utility of the system component. Replacement involves the removal of the existing non-functioning pipes or manholes and replacing them with new ones. The cost of this method, however, is generally much higher than rehabilitation alternatives. Pipe replacement jobs also take longer than pipe rehabilitation jobs. Lift Station repairs are normally done in-house. Mechanical repairs are performed at the maintenance yard. Electrical repairs are undertaken at the lift stations by Operations Staff. In general, the City maintains in stock a recommended list of spare parts which can be found in Appendix 4. Repairs requiring outside job contracts are those considered major or complex in nature such as control systems, motors and variable speed drives. These jobs are subcontracted. The City recently conducted a Wastewater System Master Plan completed by Water Systems Consulting (WSC) in December of 2012. Several methods of analysis were used in this study for all system sewer assets, including hydraulic analysis of pipelines, lift station assessments, manhole assessments, and review of system wide CCTV investigations. A list of Capital Projects addressing Rehabilitation and Replacement of existing sewer assets were identified in this study, ranked by priority, and integrated into the City's Capital Improvement Program through Fiscal Year 2017/18. Future CCTV and other R&R related investigations will be integrated into updates to this Master Plan. The City will be conducting future CCTV investigations on an "as needed" basis, when problems are encountered. City of Arroyo Grande SSMP Page 4-4 Pwrd i4Q V�', Sewer System Management Plan—Revision 01 Element 4—Sewer System Management Plan Operations and Maintenance 4.5 Capital Improvement Program (CIP) Individual Rehabilitation and Replacement Projects are identified and described in the Capital Improvement Program (CIP). A CIP budget and plan is prepared annually and covers a 5 year period. This annual report contains a planned expenditure summary for identified projects, followed by a detailed project description along with a 5 year project expenditure plan. (See CIP —Appendix 4) The City is currently in the process of adopting a Water and Wastewater Rate Study Report. This draft report was issued in March 2014. Based on the findings in the draft report, the City's wastewater enterprise fund is currently financially solvent and is anticipated to be this way for the next five (+) years. Rehabilitation & Replacement projects are shown to have adequate funding for the next five (+) years. 4.6 Employee Training Training programs include formal classroom, informal on-the-job and hands-on training. Training is conducted by both City Staff and by outside training workshops. On-the-job cross training is pursued to ensure Staff has a proficient working knowledge of the sewer system. City Staff is also cross-trained so that critical tasks can be performed without interruption even when the crew members change. Task proficiency is a requirement for all job positions and promotions. Training records are maintained to monitor completed classes and for scheduling. Crews are initially trained in the proper operation and maintenance of all new major mobile equipment and facilities by the contractor or manufacturer. Written operation and maintenance manuals are used as resource material for initial start-up training as well as new Staff training. Safety training is an integral part of the City's program. Every Staff member receives formal training. Staff is trained in confined space entry and in hazardous materials management, as required. The City is in the process of developing a Request for Proposals for the development of an Operation and Maintenance Program which will provide Standard Operating Procedures (SOPs) for O&M activities conducted within the City. These SOPs will provide the City with materials to develop a formal training program to help implement these procedures. The following procedures have been identified for development and implementation: • Lift Station Operations and Maintenance • USA Requests • Sewer Connection Requests • Routine Traffic and Crowd Control • Annual Collections System Cleaning and Reporting • High Maintenance Area Cleaning • Manhole Inspection and Maintenance • Map Updates • Stand By Pump Operation • Stand By Generator Operation • Operation of Vactor and Service Trucks The RFP for the development of this program is planned for release in October 2014. The City plans to have these procedures in place and a formal training program started by the end of 2015. City of Arroyo Grande SSMP Page 4-5 Sewer System Management Plan—Revision 01 Element 4—Sewer System Management Plan Operations and Maintenance 4.7 Equipment and Replacement Inventory Operations Staff maintain the pump stations but do not perform larger projects to repair or replace underground pipelines. Repair and replacement of underground pipelines are contracted out to licensed contractors who have the equipment, materials and personnel to complete the work. The City maintains an electronic inventory of equipment, replacement parts, and supplies and follows a structured process to ensure an up-to-date accounting and complete inventory of equipment and replacement parts. Parts required for preventive maintenance are identified ahead of time for each specific maintenance task. Parts are secured prior to the start of preventive maintenance. The City maintains equipment such as sump pumps, portable generators, traffic control and night lighting systems for emergency response. These items are maintained in a ready state for immediate deployment. Three (3) lift stations are equipped with emergency generator connections that allow the use of portable generators to operate the stations in the event of a prolonged power outage. One lift station has a permanent generator with automatic switch over. The remaining lift stations have connections which allow the use of portable trash pumps. The following pieces of equipment are utilized as backup systems in the event of a lift station emergency: • One (1) Trailer Mounted Portable 6" Pump • Two (2) Portable 3" Pumps • One (1) Fairbanks Morse 60hp submersible pump In addition to the emergency lift station equipment listed above, the City also maintains four (4) Tesco-Liquitonic 3: Level Controllers for lift stations as a backup/replacement in the event these pump controllers fail. As a backup, managers have credit authority to purchase needed materials and supplies from local vendors of non-stock items when they are critically needed. In the event of an emergency, local retailers are available to supply additional needed equipment and parts on short notice. The City has a history of purchasing plumbing and wastewater related products from the distributers listed below. They were contacted in mid-2014 and confirmed that the majority of the items required for repair and replacement are currently stocked and available for purchase. Contact information for the four (4) retailer locations is provided below: • Ferguson Enterprises: San Luis Obispo, 4546 Broad Street (805) 594-5380 • Autosys Inc: Santa Margarita, 3945 Parkhill Road (805) 438-3935 • Flo-Systems: Burbank, 3010 Floyd Street (818) 562-5282 • Perry's Electric Motor & Control: Santa Maria, 414 S. Western Ave. (805) 925-8761 As stated in Element 4, the City is also enrolled in the Cal-Warn Mutual Aid Agreement which makes the eligible to receive equipment from surrounding agencies in the event of an emergency.

If live roots are found in a sewer within six months after the application, or if a treated sewer plugs up and floods due to tree roots during the guarantee period (see below), we will re-treat that section, at our own expense, or remit to the customer 100% of the payment we received to treat that section of sewer. The decision of the customer as to the cause of the plug-up is binding. ' This guarantee applies only to sewer stoppages caused by live tree roots. It does not apply to stoppages caused by grease or other foreign matter; flat, collapsed or deformed pipe; or flooding caused by a surcharged or plugged sewer section downstream from a guaranteed sewer section. This guarantee applies to main line sewers only. Guarantee Period Any section of sanitary sewer we treat will not plug up and flood due to tree root obstructions fora period of two years. The guarantee period begins on the date of treatment, and ends two years after the date of treatment Extended Guarantee With Repeat Treatments Whenever we perform a repeat application to a section of sewer within six months of the expiration of the previous guarantee, the guarantee is extended for an additional three years. Re-treatments, performed at no charge in honor of the guarantee, do not extend the expiration date of the guarantee. r Liability Duke's is an insured, fully licensed pesticide application company, and is certified to apply EPA registered herbicides to sanitary sewers in compliance with Federal and State regulations.

The City's collection system conveys raw wastewater to trunk mains owned and operated by the South San Luis Obispo Sanitation District (SSLOCSD). Wastewater treatment and ocean disposal is also provided by SSLOCSD. According to the State of California, Department of Finance, the 2011 population was approximately 17,291 is expected to increase to 20,000 at build-out of the existing city limit. As the City corrects current capacity and age-related problems with the system infrastructure, it is the City's intent to construct wastewater system improvements consistent with the ultimate needs of the system. In order to provide wastewater collection facilities for build-out and establish a capital improvements projects program, the City contracted with Water Systems Consultants, Inc. to update the hydraulic model of the wastewater collection system. The Wastewater Master Plan was prepared to be consistent with the City General Plan and General Plan Update. Land use and population data were examined in detail along with historical demand to establish future service requirements. A comprehensive computer model of the wastewater system was developed to establish and project the capabilities of the wastewater collection system. The model was also used to identify projects for the capital improvements projects (CIP) programs, which outlines necessary improvements and upgrades for existing and future expansion wastewater system needs. The recommendations contained in this report will be reviewed periodically to ensure they continue to be consistent with current code requirements and population projections. Scope of Study The Wastewater System Master Plan was prepared to evaluate the existing wastewater collection system and recommend a program of improvements in order to provide for a well- planned and comprehensive program. The scope of the study includes the following: 1. In coordination with the City Planning Department and planning consultants, review the Land Use Element of the City General Plan through build-out of the existing City limit. 2. Estimate the current and projected average and peak wastewater flows for the collection system based on flow monitoring and available records, and estimate future flows using a detailed breakdown of land use potential provided by the City Community Development Department. City of Arroyo Grande Wastewater System Master Plan Page 1 3. Install and monitor flow recording devices to confirm flow assumptions and peaking factors. In targeted areas, review the date for the occurrence of storm water intrusion into the system. 4. Using available as-built information, prepare a comprehensive computer model of the collection system, including both gravity and pressure systems. Confirm model assumptions through field testing and flow monitoring. Analyze the collection system in terms of existing and future deficiencies. 5. Analyze each sewer lift station and force main in terms of pump hydraulic performance, and recommend improvements to be performed within a 20 year planning horizon. 6. Recommend improvements to the gravity collection system to be performed within a 20 year planning horizon. 7. Describe the City's relationship with the SSLOCSD, and Identify sewers within the City limits owned and operated by the District. Include SSLOCSD trunk mains in the comprehensive computer model. 8. Estimate the budget cost of each recommended improvement to the collection system. 9. Prepare a prioritized capital improvement program for implementation of the recommended system modifications. City of Arroyo Grande Wastewater System Master Plan Page 2 Section 1. Introduction and Overview Chapter 1 summarizes the study that was performed, and briefly presents recommendations for a program of wastewater system improvements to accommodate the build-out needs of the City. The land use patterns utilized in this study are based on the 2010 Update of the Land Use Element contained within the Arroyo Grande General Plan and on current or pending changes to this plan associated with the General Plan Amendment process. The 2010 population of the City was 17,252 according to the 2010 U.S. Census Bureau. According to the 2010 Update of the Long Range Planning Report, the population of the City is expected to grow from its current level of approximately 17,252 residents to 20,000 residents at build-out. The infrastructure improvements recommended in this document provide for the ultimate build-out of the City. f 2 Giravity Collectioiiii-i S 1 iuit The City's wastewater collection system population includes all residents located with the City of Arroyo Grande city limit. A model of the water system was developed and calibrated as part of the update. The model was used to evaluate existing wastewater collection system performance and examine alternatives for future modifications. The model and field testing indicated that the existing wastewater collection system meets demand requirements in 97%of the cases. Improvement projects were identified and modeled to address the identified deficiencies. Recommendations are also provided to meet build-out demands to enhance the reliable of the system in the future. I. tewateir Lift S1 Chit lair The City operates five (5) wastewater lift stations within its collection system. In 2006, Capital improvements were performed at Lift Station No. 1, which consists of a wet well pump configuration and conveys approximately 17%of the total City wastewater flow. In 2012 Lift Station No. 3 underwent a renovation that addressed safety and reliability issues As part of the 2012 Water and Sewer Master Plan Updates, an evaluation was performed on the City's lift stations to determine if the current capacity of each lift station is adequate for estimated build-out flows. The analysis was performed for Lift Station Nos. 1, 4, 5, and 7. Lift Station No. 3 was excluded from this analysis due that the fact it was undergoing a major upgrade to meet build-out flows at the time of the analysis. The capacity evaluation showed that Lift Station No. 1, 4, 5, and 7 all have adequate capacity to meet build-out peak hour wet weather flows (PHWWF). City of Arroyo Grande Wastewater System Master Plan Page 3 f. d Wastewater Collectioini, Ilw area ii iuitf, aiiii-id Disposal by SSL CS The South San Luis Obispo Sanitation District (SSLOCSD) is made up of three member agencies including the City of Arroyo Grande, the City of Grover Beach, and the Oceano Community Services District (OCSD). Wastewater collection (trunk sewers only), treatment, and disposal services are provided to the City of Arroyo Grande. The collection, treatment, and disposal capacity available for each member agency is not established by contract. Instead, expansion-related upgrades are funded by development impact fees that are paid when development occurs within each of the agencies. As a result, the development impact fees are calculated on a proportional basis which is dependent on the proposed project. The SSLOCSD wastewater treatment plant is currently operating at approximately 58% (2.88 mgd) of its 5.0 million gallon per day capacity. f 5 Opeiraflainis eland oiiiitiirt 1. The City system operates automatically. Operations personnel can track lift station operation at a centralized location through the Supervisory Control and Data Acquisition (SCADA) system. f 6 II t t iuit iuit ie uu-i f iii t iuit s aiiii-id Capital Il uut l uu t iui iuit f The recommendations resulting from this study are summarized in Chapter 8.

The City's distinctive character derives from its traditional ties to agriculture, physical diversity, unique village, small town atmosphere, and rural setting. The current (2010) population of the City is 17,252 according to the U.S. Census Bureau; however the City currently serves water to a population of 16,901 residents. Land Use zones within the City are established by the Land Use Element (LUE) of the General Plan. The City adopted an update to the LUE on October 9, 2001. During the LUE update process, a detailed Land Use Inventory (LUI) was prepared to quantify existing and future development (See Appendix A). The LUI was broken into 65 Traffic Analysis Zones (TAZ) within the current City limits and provided the following information for each zone. • Number of existing residential units segregated by single family, multi-family, and mobile home parks. • Existing commercial or institutional uses including additional detail on the intensity of use (building area, number of structures, etc.). • Estimated potential residential units segregated by single family or multi-family use • Estimated potential commercial or institutional uses. The Traffic Analysis Zones were small enough to be integrated and used for the tributary sewer analysis of the collection system. Wastewater flow factors for different types of development were based on metered data and type of use as described in Chapter 4 and Appendices A and B. Existing land use zones within the City are shown in Figure 3-1 and categorized in Table 3-1 City of Arroyo Grande Wastewater System Master Plan Page 5 1 a11 111e 2 ... laiid Use Ce igitatioii ullllll Vuuu I um um u�u um Gen or Exclusive 1 du/10ac.

Existing wastewater flows were assessed by utilizing the following sources of data: • Flow monitoring data from wet and dry weather sources • Lift station flow data • SSLOCSD wastewater treatment plant influent flow records Given that flow monitoring efforts were limited to a short period of time, it was necessary to determine the approximate percentage of the total flow that the City contributes to the SSLOCSD treatment facility. SSLOCSD flow data, which includes continuous flow records and daily totals, was then used to confirm seasonal peaking factor characteristics. The South San Luis Obispo County Sanitation District encompasses a geographic area of 165 square miles. It is located within an area known as the Five Cities area in the southwestern portion of San Luis Obispo County and is located 15 miles south of the City of San Luis Obispo. The SSLOCSD provides its services for the residents of the City of Arroyo Grande, the City of Grover Beach and the Oceano Community Services District. In addition, there is a small County population of approximately 50 residences that are not incorporated within the communities listed above who also receive those services offered by the District. Flow estimates were developed of the City's collection system using data from a recently completed infiltration and inflow (I/I) study prepared by the South San Luis Obispo County Sanitation District (SSLOCSD) and effluent flow data from the SSLOCSD WWTP. Effluent flow data from September 2010 through August 2011 was averaged to develop an average annual flow (AAF) for the SSLOCSD WWTP of 2.85 million gallons per day (MGD).The portion of that flow that the attributed to City's system (42%), was then applied to the SSLOCSD WWTP's AAF to obtain the AAF for the City's collection system (1.20 MGD). Table 4-1 summarizes the estimated wastewater flows of various existing development types within the City.The flow estimates employed in Table 4-1 were derived from a variety of sources including water use information, industry-standard factors, and flow meter studies of selected areas. Residential wastewater flows represent approximately 80% of the total annual average flow, which is consistent with historical water information presented in the Water Master Plan.

The "peak conditions of interest for facility design are summarized below: Average Annual Flow (AAF) is obtained by dividing the total flow conveyed by the City system in one year by 365 days. Other peak conditions are derived by multiplying the AAF by a peaking factor (PF). The flow factors in Table 4-1 reflect average annual flows. Peak Day Dry Weather Flow (PDF) is the maximum flow occurring in one day during the dry season. This flow condition is often used for the biological design of treatment processes. PDF was based on data provided by the SSLOCSD. Peak Hour Wet Weather Flow(PHWWF) is the maximum flow rate that occurs in a single hour during wet weather. Within the City, this condition will govern the design of sewers and represents the maximum flow rate that the system must convey. City of Arroyo Grande Wastewater System Master Plan Page 11 Average Day Maximum Month Dry Weather Flow reflects the maximum flow rate during the peak month of summer.This condition reflects the seasonal variation in dry weather flow. City of Arroyo Grande Wastewater System Master Plan Page 12 The table below summarizes the historical and projected peaking factors for the City.The historical peaking factors were based on all analysis of SSLOCSD data as described below. Higher peaking factors are often appropriate for the analysis of sub-areas within the system and will be noted in the analysis where appropriate. 1 4llsllle 3... ...

For the purposes of this report, these terms are defined as follows: Infiltration Infiltration is the water entering a sewer system and service connections from groundwater, through such means as defective pipes, pipe joints, connections, or manhole walls. Infiltration does not include inflow and is relatively constant over period of days,weeks, or even months as high groundwater conditions persist. Inflow Inflow is the water discharged into a sewer system and service City of Arroyo Grande Wastewater System Master Plan Page 13 connections from such sources as roof drains, cellar, yard and area drains, foundation drains, cooling water discharges, drains from springs and swampy areas, manhole covers, cross connections from storm sewers, catch basins, storm water, surface runoff, or drainage. Inflow does not include infiltration. Inflow varies rapidly with rainfall conditions, with flows rising and falling within minutes or hours of a severe storm event. d.

This powerful program is widely used in the wastewater industry. The modeling process involved the following. City of Arroyo Grande Wastewater System Master Plan Page 18 .2.1 SYst tit Kap IJpdate To update the system mapping, the existing GIS shapefiles were modified based on information obtained from as-built drawings for development and CIP projects, the City's Wastewater System Atlas and information provided by City Staff. For system components not currently contained within the GIS system mapping, individual shapefiles were developed for the following features: • Outfalls • Force Mains • Wet Wells • Sewer Nodes • Lift Stations .2.2 rilevatioti Data Ilet-ificatioti As elevation data is a critical component of a sewer system modeling. Accurate manhole invert elevation (elevation at the lowest portion of the sewer mains in the manhole) allows the existing slope of the sewer main to be calculated and is critical for determining the capacity of sewer mains. Rim elevations are also important for determining sewer depths and potential for overflows. To develop the updated sewer model, the following sources of elevation data: • sewer model developed for a 2001 Wastewater Master Plan • record drawings for recent system improvements • SSLOCSD trunk lines GIS shapefiles From these three sources, invert elevation data for 910 of the 1,701 manholes were able to be obtained within the City's collection system. To establish rim elevation data for the manhole features in the collection system, elevation data was obtained from the United States Geological Survey National Elevation Dataset (USGS NED). The USGS NED provides public domain raster elevation data for the conterminous United States, Alaska, Hawaii and territorial islands. The NED provides elevation data in the following resolutions: • 1 arc-second (approx. 30 meter grids) • 1/3 arc-second (approx. 10 meter grids) • 1/9 arc-second (approx. 3 meter grids) The best available resolution for the Arroyo Grande City Limits was 1/3 arc-second. Utilizing ArcMap, the NED raster dataset was overlaid and extracted land surface elevation data for each of the manholes in the collection system. For the City's sewer model it was assumed that the rim elevation was equal to the land surface elevation from the USGS NED.

Effluent flow data from September 2010 through August 2011 was averaged to develop an average annual flow (AAF) for the SSLOCSD WWTP of 2.85 million gallons per day (MGD). The portion of that flow that the attributed to City's system (42%), was then applied to the SSLOCSDWWTP's AAF to obtain the AAF for the City's collection system (1.20 MGD). To develop the land use sewer duty factors for the City's collection system, the spatially allocated water demands were utilized, projected build-out water demands and sewer duty factors. WSC initiated the development of the land use sewer duty factors by intersecting the spatially allocated 2010 customer water use records with the land use polygon shapefile to obtain land use water demand factors (gpd/acre). City staff identified parcels within the City Limits that are not served by the City's collection system. For the purposes of developing the sewer duty factors and land use sewer duty factors, the parcels within the City limits not served by the sewer system and the parcels outside the City Limits were excluded. Sewer duty factors, which represent the percentage of potable water that is discharged to the collection system, were originally developed based on values obtained from reference textbooks and other local sewer master plans. These percentages were then manipulated until the projected flow to the collection system matched the measured AAF flow from the SSLOCSD 1/1 study. The sewer duty factors, by land use, used to correlate the current potable water demands and wastewater flow rates and to project build-out wastewater flow rates. 4.2.5 AfodelSlceletotiizatioti During the development of the sewer model, it was determined that a significant number of the manholes in the City's collection system did not have invert elevation data available. In order to simplify the collection system model and reduce the number of manholes that could potentially require field surveying, noncritical sewer mains and manholes were removed from the sewer model or "skeletonized" the model. Skeletonization of the sewer model was achieved by fully loading the model with build-out AAF flows using the spatial allocation methodology described above. Flow rates through the model were then evaluated and any pipes or manholes with a flow of less than 19,000 gpd were removed from the model.This flow equates to peak hour flow of 6,690 gpd and a peak hour flow depth pipe diameter ratio (d/D) of less than 0.5 at an assumed minimum slope of 0.001 in a 6in pipe and a d/D of 0.5 at a slope of 0.0002 in an Bin City of Arroyo Grande Wastewater System Master Plan Page 31 pipe, assuming a roughness coefficient of 0.014. Pipelines removed from the model using this methodology will have capacity to meet build-out flows as long as the installed slope is greater than the assumed minimum slope. For comparison the minimum slope assumed for an Bin pipe was 0.1%, the minimum recommend slope for installation of an Bin pipe is 0.35%, thus this is a conservative removal or skeletonization methodology. Once skeletonized the model did not require any field surveying to determine invert elevations. Any missing invert elevations in the skeletonized model were interpolated from the upstream and downstream manholes. Once the model was skeletonized, demands to the remaining nodes were redistributed within each sewershed. After the skeletonized model was re-loaded, the flow rates were compared along the remaining trunk lines to determine if the skeletonization altered the distribution of the wastewater flows. Adjustments were made to loading at several locations so that the distribution of wastewater flows in the skeletonized model would closely mimic the un- skeletonized model. The following design criteria are recommended for the analysis of gravity sewers: Flow Condition Allowable Flow Depth(d/D) Avg. Dry Weather Flow 0.5 Peak Dry Weather Flow 0.75 Peak Wet Weather Flow 0.9 • The flow depth was calculated based on the computer generated backwater curve. • A minimum pipeline velocity of 2.0 feet per second should be maintained. It should be noted that the computer model analyzes the gravity sewer system as an integrated unit through a backwater analysis. Another generally accepted method for determining sewer capacity and flow depth is the Manning's Equation, which was also checked to confirm sewer capacity.The ratio of flow depth to pipe diameter (d/D) predicted by the Manning's Equation is displayed for existing and future conditions. Sewers with a d/D of greater than 0.5 were selected for additional analysis and review. d. Lift Sf fiiit uu- Evalu fiiit lair An evaluation of the City's lift stations to determine if the current capacity of each lift station is adequate for estimated build-out flows. The analysis was performed for Lift Station Nos. 1, 4, 5, and 7. In 2011 Lift Station No. 3 underwent a major upgrade to meet build-out flows and thus was excluded from this analysis. The capacity evaluation showed that Lift Station Nos. 1, 4, 5, and 7 all have adequate capacity to meet build-out peak hour wet weather flows (PHWWF). City of Arroyo Grande Wastewater System Master Plan Page 32 This memorandum provides a brief summary of the lift station capacity evaluation method and results. The capacity evaluation required two primary steps: (1) determining the current lift station capacity, and (2) estimating build-out lift station capacity requirements. System curves were developed for each lift station based on record drawings. Key inputs to creating the system curves included the following: • Lift station high water level (HWL) • Lift station low water level (LWL) • Force main discharge invert elevation • Force main length and diameter • Size, number and type of fittings on pump manifold (impeller to pump manifold) • Size, number and type of fittings on force main (pump manifold to gravity invert) Using this data, the system curve was calculated for both the best case and the worst case. The best case is defined as the case with the lowest static head (water level at HWL) and the lowest friction losses (highest roughness factor, i.e. smooth pipe). The worst case is defined as the case with the highest static head (water level at LWL) and the highest friction losses (lowest roughness factor, i.e. rough pipe). Pump curves were obtained for each lift station and plotted these with the calculated system curves to determine the operating point for each lift station. Because both a best and worst case system curve were calculated, this analysis yielded a capacity range (gpm) for each lift station. The pump and system curves for Lift Station 1, 4, 5, and 7 are included below. Note that while Attachment 1 presents curves for both simplex operation (one pump operating) and duplex operation (two pumps operating), only simplex operation is used for the capacity analysis because the City only operates one pump at a time, with the second pump serving as backup. 4.3.2 Ctipacity Requit-ed'at Build'-out The lift station must have sufficient capacity to meet the build-out PHWWF. The build-out PHWWF was calculated by applying a peaking factor to the average annual daily flow (AAF) estimated for each sewershed at build-out. An analysis was performed for two different peaking factors: (1) a peaking factor of 2.84, which is the estimated to be the city-wide peaking factor (calculated using the Babbitt equation), and (2) a peaking factor of 3.5, which is more conservative as the individual lift stations may experience a peaking factor greater than the City of Arroyo Grande Wastewater System Master Plan Page 33 city-wide average peaking factor (because the lift stations serve a smaller subset of the overall city population). This yielded the capacity requirements of each lift station at build-out. 4.3.3 Results The build-out capacity requirements and the calculated current capacity for each lift station are shown in the table below. In addition, the table also presents the rated capacity and actual measured flow data for comparison. The rated, calculated and measured capacity of each lift station exceeds the build-out PHWWF for a 3.5 peaking factor. Based on this analysis, the current capacity of each lift station is adequate to meet build-out flows.

Draw down and amperage testing were performed on Lift Station 1, 4, 5, and 7, in August 2011. The flowrate measured during the draw down test for each lift station is the measured capacity shown in the table. The amperage testing did not yield conclusive results because data for only this single data point in time is known. This does not allow for performance comparisons of the same winding overtime to determine how performance ischanging. Draw down and amperage testing is recommended to be performed in the future in order to provide the City three (3) data points for each pump/motor. With three (3) data points, the City can evaluate trends over time and determine if equipment replacement isnecessary. The calculated system curve displaying the operating regions for the lift stations follows.

The SSLOCSD is governed by a three member board of directors comprised of a representative from each of its member agencies. Member agencies include the City of Arroyo Grande, the City of Grover Beach, and the Oceano Community Services District. Wastewater collection (trunk sewers only), treatment, and disposal services are provided to each agency as described below: 1 Wastewateir ollectiiit iuit Puirwiitk Seweirs SSLOCSD owns and maintains a system of trunks within its member agencies, including the City of Arroyo Grande. The figure below shows the SSLOCSD trunks, which vary between18" and 27" in diameter. The majority of the system was constructed in 1966. The trunk capacity available for each member agency is not established by contract and no capacity allotment exists for each agency. However, the SSLOCSD collects impact fees from new development projects within each member agency, and the funds are used for expansion related improvements. As a result, those agencies which sustain the most new development contribute a greater share to SSLOCSD system expansion. Since the hydraulic characteristics of trunk sewers impact the City collection system, the SSLOCSD trunks were included in the computer model. However, the City is only responsible for constructing improvements to the City-owned portion of the system.The existing 30" and36" diameter SSLOCSD trunk mains downstream of the City are adequate to accommodate future City flows and currently anticipated SSLOCSD flows (7.5 mgd treatment plant capacity). Wastewateir Ilw ireatiuit iuitl uu Disposal SSLOCSD owns and operates a wastewater treatment and ocean disposal facility with an average annual flow capacity of 5.0 million gallons per day. The system consists of a secondary treatment facility including the following process elements: • Headworks-flow meter and raw wastewater pump station • Primary clarification • Secondary treatment in a biological trickling filter • Secondary clarification • Disinfection and dechlorination • Gravity ocean outfall (shared with the City of Pismo Beach) City of Arroyo Grande Wastewater System Master Plan Page 45 The treatment system is operating at approximately 58%of capacity (2.88 mgd). As with trunk capacity, wastewater treatment and disposal capacity is not established by contract and is therefore not apportioned among the member agencies. An update recycled water feasibility study was completed by the SSLOCSD in February 2010. The study addressed the feasibility of delivering secondary or tertiary recycled water to member agencies or other users, including the City of Arroyo Grande. One constraint to the efficient production of recycled water identified in the study was the elevated salt levels present in SSLOCSD treated effluent, which could require reverse osmosis treatment prior to reuse. Given that treated effluent is currently discharged to a highly concentrated salt environment (the ocean), the existing SSLOCSD discharge permit does not place a limitation on salts or require the implementation of salt management practices. The City is currently considering a recycled water program and plans to pursue recycled water in the future. The following recycled water studies have been completed with the goal of identifying potential recycled water projects, which would benefit the City: - Water Recycling Progress Report, Prepared for South San Luis Obispo County Sanitation District, Prepared by John L. Wallace&Associates, February 2001 - Recycled Water Distribution System Conceptual Plan-South San Luis Obispo County Sanitation District WWTP Technical Memorandum, Prepared by the Wallace Group,June 2010 - Recycled Water Distribution System Conceptual Plan- City of Pismo Beach WWTP Technical Memorandum, Prepared by the Wallace Group,June 2010 - Water Recycling Update report, Prepared for South San Luis Obispo Sanitation District, Prepared by the Wallace Group,January 2009 City of Arroyo Grande Wastewater System Master Plan Page 46 Sectio Collection y e p Ma.intena.nce and Inspection Initiated in 1990, the City's cleaning program has helped reduce line blockages, odor complaints, and lift station failures. Maintenance is approached in two ways: preventive and corrective. Corrective maintenance is considered to be a physical collapse of an existing sewer; stoppage due to roots, FOG, or other foreign materials; inflow or infiltration; or pump failure. These conditions require immediate action to correct the problem and are further discussed in Element 6 of the City of Arroyo Grande Sewer System Management Plan Preventive maintenance involves inspection of the sewer system and analysis of existing data to identify trouble areas. Inspection and analysis can provide guidance in determining the type, degree, and frequency of preventive maintenance required. The objectives of both are to improve service, reduce emergency occurrences, and to minimize the cost of the preventive maintenance program. In general, the greater the amount of preventive maintenance performed, the less the amount of corrective maintenance that will be required. :f Il ii p e iii ii-i ii ii-il iria iii-i The City of Arroyo Grande has developed a year-round pipeline maintenance program with an emphasis on preventive maintenance, especially in historical trouble areas which are checked at more frequent intervals. The system is videoed in suspected trouble areas and the entire system is cleaned and flushed annually. Based on cleaning, flow analysis and video, the city determines which area of the pipeline system would benefit the most by rehabilitation or replacement. Quarterly cleanings are performed at historical problem areas based on field crew experience.The city also participates in an active FOG Program. IIIIihol Mai,IIII-teIIri IIII-i ", The City of Arroyo Grande uses visual manhole inspections, as part of day to day maintenance. Visual inspections are an inexpensive and quick method of detecting inflow/infiltration sources, the general structural condition of the manhole, and the accuracy of previous system drawings. Visual and video manhole inspections are used to determine the following: • Exact location of the manhole; • Condition of cover and frame (defects that may allow inflow); • Is the cover subject to ponding or surface run off; • Potential area that drains to any defects; City of Arroyo Grande Wastewater System Master Plan Page 47 • Condition of benching, risers, grade rings and collar; and • Condition of sewer pipes. Manhole repairs are required to correct structural deficiencies, effects of corrosion on the internal surface, and to eliminate the inflow of surface or groundwater. The City of Arroyo Grande continues to install manhole inflow covers to minimize potential infiltration. In the absence of adequate oxygen, bacteria living in municipal wastewater begin to convert sulfate, a common sewer constituent, into a dissolved compound know as hydrogen sulfide (H,S). This compound subsequently escapes the wastewater, particularly in areas of high turbulence, and enters the air environment as a gas. Once the gas is present in a gravity collection system, it can escape through man-hole covers, roof vents, and lift stations, causing an offensive rotten-egg odor in areas of release. At higher concentrations, the gas can cause eye irritation, respiratory problems, and even death. In addition to its odorous properties, the gas can form sulfuric acid in the presence of air. This acid will corrode concrete and other materials often found in wastewater collection systems. Typically, oxygen levels in gravity wastewater systems remain adequately high to prevent the formation of excessive hydrogen sulfide. However, the gas forms readily in the following common components of a collection system: • Lift station wet wells where wastewater can be stored for more than 30 minutes during low flows. • Long wastewater force mains where the absence of an air-water interface contributes to anaerobic conditions. • Areas within a gravity collection system where solids have deposited due to inadequate velocities or lack of cleaning. The primary area of concern in the City is the force main discharge. Hydrogen sulfide-related corrosion is evident in downstream manholes. As gravity sewers are replaced downstream of lift Stations, it is recommended that all new manholes receive a corrosion-resistant coating. Lift SL fiiit uu-i Mai rout iuit uutt The City of Arroyo Grande maintains five (5) lift stations. Duplication of equipment and functions provides the flexibility necessary for continued operation during individual shutdowns due to scheduled maintenance or emergencies. Weekly inspections are performed on the lift stations that include the seal filters, electrical equipment, instrumentation, wet well, screening devices, venting and housekeeping. Weekly lift station and wet well inspections are performed by field crews and the wet wells are cleaned quarterly. City of Arroyo Grande Wastewater System Master Plan Page 48 Sectio Recommendations Capital Improvements The results of this study are presented in this chapter as the recommended Master Plan and Capital Improvements Project program for water system facilities in the City of Arroyo Grande. The Master Plan consists of staged improvements to correct existing deficiencies and provide for future system expansion. Cost estimates were prepared and used to develop a capital cost program. The proposed improvements are needed to connect existing wastewater system deficiencies and provide for the ultimate build out of the system within the existing City boundaries. The wastewater system was evaluated using the SewerGEMS water system modeling program which identified flow rates throughout the system for the specified conditions. These flow conditions are those expected to be experienced by the wastewater collection system. The collection system and sewer lift stations were evaluated for their ability to meet the build-out demands of the system under maximum use conditions. In addition to meeting flow requirements, the recommended collection improvements have been selected to provide system reliability. This chapter outlines the methodologies used to identify the projects recommended in this CIP and to develop project cost opinions. 7 :f Data t ll tliiit uu-i aiad Field Lavesti Liiioia Data collection included City reports, customer water usage and water production data, existing sewer models, and a GIS land use database. In addition, City staff interviewed to gain insight on current operation of the sewer systems and areas known to need improvement. Site visit were performed at all lift stations to review facility condition. Drawdown testing was performed at all lift stations (excluding Lift Station 3, which is currently being replaced).The drawdown testing included measurements of flow rate and motor amperage, for 3 cases: pump 1 running, pump 2 running, and both pumps running. This provided instantaneous capacity data for each lift station. Neither long term flow data nor run time information was available. 7 2 Mappiiiag, Popul liiioiia, Laii-id U se aiad Deii-naii-id Piuroje liiioiiit The sewer system maps were updated to reflect the current systems. An iterative process was used to create maps that are as accurate as possible based on the available information. The population served by the City's wastewater collection system was estimated using the 2010 Census data for the City of Arroyo Grande. Current and buildout acreage by land use category were estimated using City land use data and a 200913reliminary Housing Opportunity Sites City of Arroyo Grande Wastewater System Master Plan Page 49 Inventory (Inventory) provided by the City. The land use data provided the number of acres of each land use category at buildout. The Inventory provided a list of parcels with development potential including the parcel acreage, existing number of dwelling units, and estimates of the number of potential dwelling units that could fit within each parcel. WSC used the data provided in the Inventory to estimate the undeveloped acreage by land use. WSC estimated current developed acreage for each land use category by subtracting the estimated undeveloped acreage identified in the Inventory from the buildout acreage for each land use category. Metered flow data for two City sewer outfalls to the South San Luis Obispo County Sanitation District (SSLOCSD) trunk line was obtained. Using this data, along with SSLOCSD's Inflow and Infiltration Study (August 3, 2011) and water demand factors, WSC calculated buildout wastewater flow factors (gpd/acre) for each land use category. 7 sate Liam t ll tliiit iuit Systeii-n Capacity Evalu L oiiit A SewerGEMS® model was created of the City's wastewater collection system, including gravity sewer mains, force mains, and lift stations. The available sewer pipe invert and slope information is generally limited to large diameter mains modeled in the previous master plan, therefore much of the collection system does not have the required data readily available to analyze the pipeline capacity. In order to simplify the collection system and reduce the number of manholes that require a field survey, noncritical sewer mains were removed from the model. The simplification of a hydraulic model by removing pipelines that do not need analysis is known as skeletonizing. The Arroyo Grande sewer collection system was skeletonized by evaluating projected buildout pipeline flows and eliminating pipes from the model that had future average annual daily flows less than 19,000 gpd. The skeletonized model did not require field surveying to determine invert elevations and pipe slope, the previous model had slope information for the remaining pipelines. Loading was applied using sewer sheds. 7 d. SCADA. Systeiiiiii Evalu l oiiit An evaluation of the City's SCADA system was performed by conducting field visits to various SCADA sites to understand the City's current SCADA system and identify deficiencies. Based on data collected during the field visits and provided by the City, SCADA software and radio improvements were identified. The cost opinions (estimates) included in this CIP are based upon the Class 4 Conceptual Report Classification of Opinion of Probable Construction Cost as developed by the Association for the Advancement of Cost Engineering (AACE) Cost Estimate Classification System. The purpose of a Class 4 Estimate is to provide a conceptual level effort that has an expected accuracy range City of Arroyo Grande Wastewater System Master Plan Page 50 from -30%to +50% and the inclusion of an appropriate contingency for planning and feasibility studies. The conceptual nature of the design concepts and associated costs presented in this CIP are based upon limited design information available at this stage of the projects. These cost estimates have been developed using a combination of data from RS Means CostWorkso, recent bids, experience with similar projects, current and foreseeable regulatory requirements, specific City requirements, and an understanding of the necessary project components. As the projects progress, the design and associated costs could vary significantly from the project components identified in this CIP. The recommended projects and these cost opinions are based on the following assumptions: 1. For projects where applicable cost data is available in RS Means CostWorkso (e.g. pipeline replacement), cost data released in Quarter 4 of 2011, adjusted for San Luis Obispo, California, is used. Material prices were adjusted in some cases to provide estimates that align closer with actual local bid results. 2. For projects where RS Means CostWorks® data is not available, cost opinions are generally derived from bid prices from similar projects, vendor quotes, material prices, and labor estimates, with adjustments for inflation, size, complexity, and location. 3. Cost opinions are in 2011 dollars. When budgeting for future years, appropriate escalation factors should be applied (ENR Construction Cost Index of: 9171.73 for December 2011). 4. Cost opinions are "planning-level" and may not fully account for site-specific conditions that will affect the actual costs, such as soils conditions, and utility conflicts. 5. Per the City's standards, design services, which includes an allowance for alternatives analysis, design phase engineering, surveying, and permitting, are included at a rate of 15 percent of the estimated construction cost. 6. Per the City's standards, contract administration services during construction are included at a rate of 10 percent of the estimated construction cost. 7. Per the City's standards, a construction contingency of 10 percent of the estimated construction cost has been included. The opinions of probable cost prepared by WSC represent our judgment and are supplied for the general guidance of the City. Since WSC has no control over the cost of labor and material, or over competitive bidding or market conditions, WSC does not guarantee the accuracy of such opinions as compared to contractor bids or actual costs. City of Arroyo Grande Wastewater System Master Plan Page 51 The sewer system project recommendations address improvements to the sewer collection system. The projects have been divided into three groups, Priority A, B, and C, where Priority A projects have the highest priority. In general, Priority A projects are needed to ensure safe system operation, reduce I/I and prevent spill. Priority B projects address longer-term needs, often related to future growth or improvements that enhance system reliability or other low- level risks. Priority C projects include recommended long term annual or recurring projects. The table below provides a summary of the sewer system CIP projects.

Supporting Information: The 8-inch cast iron forcemain carrying flow leaving Lift Station 1, was installed in about 1973, making the forcemain 41 years old. City staff report that there have been one major and one minor break in the forcemain in recent years, an indicator that the forcemain has exceeded its useful life. Recommended Solution: It is recommended that the City replace the existing 8-inch cast iron forcemain with an 8-inch PVC forcemain, as shown in the figure. The length of the forcemain is approximately 3,070-LF.

This would reduce the capacity of the main and increase energy costs relative to the construction of a new main. Construction would involve a lengthy bypass of the existing forcemain. Bypass is not only expensive, but carries risk of a sewage spill. WSC recommends the design engineer prepare a detailed analysis of lining versus a new forcemain because utility conflicts in W. Branch Street could mean temporary bypass pumping is required even to construct a new forcemain. This will not be known until detailed utility research is prepared for W. Branch Street during the design phase.

Supporting Information: The hydraulic model indicates that the buildout peak flow along this section of sewer mains will reach 570,000 gpd. This leads to a d/D ratio ranging from 0.56 to 0.89 which exceeds the design criteria for an 8-in sewer main of 0.6 d/D. The 0.56 d/D occurs in a section of 8-in sewer in the middle of the alignment with a slightly steeper slope than the surrounding pipelines; however, it is not prudent to design a large diameter pipe feeding into a smaller pipe then expanding to a larger pipe on the other side. So although technically a small section of the alignment meets the design criteria of 0.6 d/D maximum, upgrading the adjacent pipes means all should be upgraded at the same time. This section of sewer also has a section with two parallel mains, WSC recommend consolidating the two mains into one 12-in main with this project. Recommended Solution: It is recommended that the City upgrade the existing 1,850-1-F section of 8-in clay sewer main to a 12-in PVC sewer main. Upgrading this section of sewer main will reduce the flow depth in the pipeline to a d/D ranging from 0.31 to 0.41 under buildout peak flow conditions.

These sewer sections are located at: (1) 216 Pilgrim Way to West Cherry Ave (2) West Cherry Ave to Fair Oaks Ave (east), and (3) West Cherry Ave to Fair Oaks Ave (west). Supporting Information: Due to their location, these sewer mains are difficult to access and could be damaged by the residents. Moving these sewer sections will improve the City's ability to access and maintain these sewers and reduce the impact on the residents. Recommended Solution: It is recommended that the City construct three (3) replacement sewer mains in the right-of- way of the adjacent streets and abandon the existing sewer mains located in the residential backyards. The lengths of the proposed mains are shown in the table below and figure below shows the locations of the existing and proposed sewers.

El Camino Real Sewer Upgrade Design and Permitting: 10 months Construction: 8 months Opinion of Total Project Cost: $ 911,800 Need for Project: The existing sewer mains downstream of Lift Station 1, along El Camino Real to Bennett Ave, have insufficient capacity for current and buildout peak flows. Supporting Information: Lift Station 1 was upgraded in 2006. With this upgrade, a peak flow of 800-gpm leaves the lift station using the previously constructed 8-in cast iron pipe forcemain. The primary gravity sewer that receives the flow from the Lift Station 1 forcemain is a 10-inch sewer, which runs along El Camino Real. At Brisco Rd, the sewer connects to a 12-inch sewer that runs to Bennett Ave. The length, diameter, estimated buildout flow and calculated segment capacity for each segment. The maximum capacity is based on the pipe material, existing slope, and the design criteria of a maximum d/D of 0.6 for 12-in diameter and less gravity sewer pipelines. Thus, the capacity of the sewer mains need to be increased to accommodate buildout peak flows. City of Arroyo Grande Wastewater System Master Plan Page 113 i aII IIIe "E...5...

Supporting Information: The City's collection system currently contains numerous manholes that have deteriorated and/or experienced structural fatigue. Various physical factors, such as subsidence from traffic loading, shifting and expanding soils, temperature variation and cyclic groundwater levels can lead to the weakening of manholes. Additionally, the environmental conditions within the collection system can cause microbial induced corrosion. Microbial induced corrosion can rapidly destroy concrete-based materials in the collections system. Structurally compromised or deteriorated manholes can lead to increased infiltration and/or leakage of wastewater into the ground. Recommended Solution: It is recommended that the City evaluate the condition of its manholes and prioritize the replacement or rehabilitation of the most deteriorated manholes. The project includes rehabilitation of up to 500 manholes using a cured in place epoxy lining system. Due to the number of manholes requiring rehabilitation, it is recommended that the City perform the manhole rehabilitation projects in phases, beginning with the highest priority areas. To determine the highest priority areas, it is recommended that the City perform a preliminary study to assess which manholes pose the highest risk. Additionally, the City should couple manhole rehabilitation projects with other larger projects in the same area when possible. Alternatives: City of Arroyo Grande Wastewater System Master Plan Page 119 A do-nothing alternative is not recommended as it could result in complete structural failure, increase infiltration and wastewater leakage.

Supporting Information: SSLOCSD recently completed an 1/1 Study in August 2011. This study indicated that a large volume of 1/1 was detected at manholes downstream of the Arroyo Grande sewershed.1 The increased flows from the Arroyo Grande sewershed were indicative of both inflow and infiltration. The study also indicated that the siphon crossing under the Arroyo Grande Creek may be contributing to the 1/1 flow. The creek crossing pipeline is owned and maintained by SSLOCSD. The figure below shows the flow monitoring data from the SSLOCSD 1/1 study by flow monitoring basin. Flow from the Arroyo Grande monitoring basin peaked on March 20th, when rainfall exceeded over two inches. 1 South San Luis Obispo County Sanitation District(SSLOCSD),Inflow and Infiltration Study, Final Report.Prepared by Wallace Group.August 3,2011.

Reviewed by: Jeffery Szytel, P.E. Project: City of Arroyo Grande 2011 Water and Sewer Master Plan Updates SUBJECT: APPENDIX C— LIFT STATION ENERGY CONSIDERATIONS The purpose of Collection System Modeling Technical Memorandum (TM) is to describe the development of the collection system model for the purposes of evaluating system capacity. This TM contains the following sections: (1) System Mapping Update (2) Elevation Data (3) Sewer Flow Rates (4) Land Use Sewer Duty Factors (5) Spatially Allocated Flows (6) Model Skeletonization (7) Collection System Modeling System Mapping Update The last major revision to the City's GIS mapping for the sewer system was completed in 2003. Developing an updated sewer model required updated sewer system GIS mapping. To update the system mapping, WSC modified the GIS shapefiles based on information obtained from as-built drawings for development and CIP projects, the City's Wastewater System Atlas and information provided by City Staff. For system components not currently contained within the GIS system mapping, WSC developed individual shapefiles for the following features: City of Arroyo Grande Wastewater System Master Plan Page 125 ?f/////a" Technical Memorandum """,/ S C ➢ Outfalls ➢ Wet Wells ➢ Lift Stations ➢ Force Mains ➢ Sewer Nodes ➢ Lift Stations Elevation Data Elevation data is a critical component of a sewer system model. Accurate manhole invert elevation (elevation at the lowest portion of the sewer mains in the manhole) allows the existing slope of the sewer main to be calculated and is critical for determining the capacity of sewer mains. Rim elevations are important for determining sewer depths and potential for overflows. Invert Elevations The City's existing GIS system does not currently contain invert elevation data. To develop the updated sewer model, WSC used the following sources of elevation data: ➢ sewer model developed for a 2001 Wastewater Master Plan ➢ record drawings for recent system improvements ➢ SSLOCSD trunk lines GIS shapefiles From these three sources, WSC was able to obtain invert elevation data for 910 of the 1,701 manholes within the City's collection system. Rim Elevations To establish rim elevation data for the manhole features in the collection system, WSC obtained elevation data from the United States Geological Survey National Elevation Dataset (USGS NED). The USGS NED provides public domain raster elevation data for the conterminous United States, Alaska, Hawaii and territorial islands. The NED provides elevation data in the following resolutions: ➢ 1 arc-second (approx. 30 meter grids) ➢ 1/3 arc-second (approx. 10 meter grids) ➢ 1/9 arc-second (approx. 3 meter grids) City of Arroyo Grande Wastewater System Master Plan Page 126 "W Technical Memorandum %Illlolg� °' S C The best available resolution for the Arroyo Grande City Limits was 1/3 arc-second. Utilizing ArcMap, WSC overlaid the NED raster dataset and extracted land surface elevation data for each of the manholes in the collection system. For the City's sewer model it was assumed that the rim elevation was equal to the land surface elevation from the USGS NED. Sewer Flow Rates WSC developed estimates of flow through the City's collection system using data from a recently completed infiltration and inflow (1/1) study prepared by the South San Luis Obispo County Sanitation District (SSLOCSD) and effluent flow data from the SSLOCSD WWTP. Effluent flow data from September 2010 through August 2011 was averaged to develop an average annual flow (AAF) for the SSLOCSD WWTP of 2.85 million gallons per day (MGD). The portion of that flow that the attributed to City's system (42%), was then applied to the SSLOCSD WWTP's AAF to obtain the AAF for the City's collection system (1.20 MGD). Land Use Sewer Duty Factors To develop the land use sewer duty factors for the City's collection system, WSC utilized the spatially allocated water demands, projected build-out water demands and sewer duty factors. WSC initiated the development of the land use sewer duty factors by intersecting the spatially allocated 2010 customer water use records (see Water Modeling TM) with the land use polygon shapefile to obtain land use water demand factors (gpd/acre). City staff identified parcels within the City Limits that are not served by the City's collection system. For the purposes of developing the sewer duty factors and land use sewer duty factors, the parcels within the City limits not served by the sewer system and the parcels outside the City Limits were excluded (see Water Modeling TM). Sewer duty factors, which represent the percentage of potable water that is discharged to the collection system, were originally developed based on values obtained from reference textbooks and other local sewer master plans. These percentages were then manipulated until the projected flow to the collection system matched the measured AAF flow from the SSLOCSD 1/1 study. Table 6 below shows the sewer duty factors, by land use, used to correlate the current potable water demands and wastewater flow rates and to project build-out wastewater flow rates.

VIII, IIIIU � 'u„„ II Spatially Allocated Flows To develop the spatially allocated flows for the City's sewer collection system, WSC applied the land use sewer duty factors to the build-out land use area for each lift station's and outfall's tributary or sewershed area. The connections to the SSLOCSD were represented in the GIS system and sewer model as outfalls. The total projected flow for each lift station and outfall sewershed was then divided evenly across the nodes within that sewershed. Individually spatially allocated demands for the sewer system were not used because flow data for each customer connection is not known. Minor City of Arroyo Grande Wastewater System Master Plan Page 129 "W Technical Memorandum %Illlolg� °' S C adjustments to flows through the collection system were made to calibrate or allow the model to mimic the flow rates observed during the SSLOCSD's 1/1 study. Model Skeletonization During the development of the sewer model, WSC determined that a significant number of the manholes in the City's collection system did not have invert elevation data available. In order to simplify the collection system model and reduce the number of manholes that could potentially require field surveying, WSC removed non-critical sewer mains and manholes from the sewer model or "skeletonized" the model. Skeletonization of the sewer model was achieved by fully loading the model with build-out AAF flows using the spatial allocation methodology described above. Flow rates through the model were then evaluated and any pipes or manholes with a flow of less than 19,000 gpd were removed from the model. This flow equates to peak hour flow of 6,690 gpd and a peak hour flow depth pipe diameter ratio (d/D) of less than 0.5 at an assumed minimum slope of 0.001 in a 6in pipe and a d/D of 0.5 at a slope of 0.0002 in an Bin pipe, assuming a roughness coefficient of 0.014. Pipelines removed from the model using this methodology will have capacity to meet build-out flows as long as the installed slope is greater than the assumed minimum slope. For comparison the minimum slope assumed for an Bin pipe was 0.0010, the minimum recommend slope for installation of an Bin pipe is 0.0035, thus this is a conservative removal or skeletonization methodology. Once skeletonized the model did not require any field surveying to determine invert elevations. Any missing invert elevations in the skeletonized model were interpolated from the upstream and downstream manholes. Once the model was skeletonized, WSC redistributed the demands to the remaining nodes within each sewershed. After the skeletonized model was re-loaded, WSC compared the flow rates along the remaining trunk lines to determine if the skeletonization altered the distribution of the wastewater flows. Adjustments were made to loading at several locations so that the distribution of wastewater flows in the skeletonized model would closely mimic the un-skeletonized model. Collection System Modeling To evaluate the need for improvements to the City's sewer system, WSC used the calibrated model to analyze the collection system's ability to meet the minimum pipe velocity and d/D criteria. The specific evaluation criteria utilized for the collection system evaluation is contained in the Evaluation Criteria TM and where appropriate the Capital Improvement Program (CIP) projects were supported with sewer model runs.

Reviewed by: Jeffery Szytel, P.E. Project: City of Arroyo Grande 2011 Water and Sewer Master Plan Updates SUBJECT: APPENDIX B— LIFT STATION CAPACITY EVALUATION As part of the 2011 Water and Sewer Master Plan Updates, WSC performed an evaluation of the City's lift stations to determine if the current capacity of each lift station is adequate for estimated build-out flows. The analysis was performed for Lift Station 1, 4, 5, and 7. Lift Station 3 is currently undergoing a major upgrade to meet build-out flows and thus was excluded from this analysis. The capacity evaluation showed that Lift Station 1, 4, 5, and 7 all have adequate capacity to meet build- out peak hour wet weather flows (PHWWF). This memorandum provides a brief summary of the lift station capacity evaluation method and results. The calculated system curves, which show operating regions for the lift stations, are included as Attachment 1. Method The capacity evaluation required two primary steps: (1) determining the current lift station capacity, and (2) estimating build-out lift station capacity requirements. These two steps of the analysis are described briefly here. Cut-t-ent Lift Station Ctipaci�y WSC developed system curves for each lift station based on record drawings. Key inputs to creating the system curves included the following: • Lift station high water level (HWL) • Lift station low water level (LWL) • Force main discharge invert elevation City of Arroyo Grande Wastewater System Master Plan Page 131 "W Technical Memorandum %Illlolg� °' S C • Force main length and diameter • Size, number and type of fittings on pump manifold (impeller to pump manifold) • Size, number and type of fittings on force main (pump manifold to gravity invert) Using this data, WSC calculated the system curve for both the best case and the worst case. The best case is defined as the case with the lowest static head (water level at HWL) and the lowest friction losses (highest roughness factor, i.e. smooth pipe). The worst case is defined as the case with the highest static head (water level at LWL) and the highest friction losses (lowest roughness factor, i.e. rough pipe). WSC obtained pump curves for each lift station and plotted these with the calculated system curves to determine the operating point for each lift station. Because both a best and worst case system curve were calculated, this analysis yielded a capacity range (gpm) for each lift station. The pump and system curves for Lift Station 1, 4, 5, and 7 are included as Attachment 1. Note that while Attachment 1 presents curves for both simplex operation (one pump operating) and duplex operation (two pumps operating), only simplex operation is used for the capacity analysis because the City only operates one pump at a time, with the second pump serving as backup. The lift station must have sufficient capacity to meet the build-out PHWWF. WSC calculated the build- out PHWWF by applying a peaking factor to the average annual daily flow (AAF) estimated for each sewershed at build-out. WSC performed the analysis for two different peaking factors: (1) a peaking factor of 2.84, which is the estimated to be the city-wide peaking factor (calculated using the Babbitt equation), and (2) a peaking factor of 3.5, which is more conservative as the individual lift stations may experience a peaking factor greater than the city-wide average peaking factor (because the lift stations serve a smaller subset of the overall city population). This yielded the capacity requirements of each lift station at build-out. Results The build-out capacity requirements and the calculated current capacity for each lift station are shown in Table 8. In addition, Table 8 also presents the rated capacity and actual measured flow data for comparison. The rated, calculated and measured capacity of each lift station exceeds the build-out PHWWF for a 3.5 peaking factor. Based on this analysis, the current capacity of each lift station is adequate to meet build-out flows.

The flowrate measured during the draw down test for each lift station is the measured capacity shown in Table 8. The amperage testing did not yield conclusive results because data for only this single data point in time is known. This does not allow for performance comparisons of the same winding over time to determine how performance is changing. WSC recommends performing the draw down and amperage testing in 2012 and 2013, which will give the City three (3) data points for each pump/motor. With three (3) data points, the City can evaluate trends over time and determine if equipment replacement is necessary.

Reviewed by: Jeffery Szytel, P.E. Project: City of Arroyo Grande 2011 Water and Sewer Master Plan Updates SUBJECT: APPENDIX C— LIFT STATION ENERGY CONSIDERATIONS The purpose of this analysis was to investigate the energy use of the City of Arroyo Grande's lift stations. These energy considerations will support the development of the Sewer System Master Plan Update. From the results of this analysis, WSC recommends the following two actions: (1) Perform a detailed energy investigation of Lift Station 1, including a pump efficiency test. (2) Consult with the City's PG&E account representative about changing the PG&E rate schedule for the electric meter serving Lift Station 5. Data WSC obtained energy billing data from Pacific Gas and Electric Company (PG&E) for Lift Stations 1, 3, 4, and 5, for approximately 2008 through 2010. WSC was not able to access energy usage for Lift Station 7 because the PG&E electricity bill for Lift Station 7 is paid by a private development, not the City. The compiled energy usage for the lift stations for 2008—2010 is shown in Figure 18. The tabulated energy usage and energy costs are shown in Table 9. Note that the PG&E billing cycles do not align exactly with the calendar month and calendar year; thus, the data shown for City of Arroyo Grande Wastewater System Master Plan Page 143 "W Technical Memorandum ° drr� SC each year represents an approximate value for that year, estimated using data for one year beginning with the first full billing cycle in each year(i.e. the 2008 total is tabulated from PG&E billing data from mid-January 2008, through mid-January 2009). The energy analysis was limited to a high-level investigation due to limited availability of data. Flow records for the lift stations were not available. In addition, pump efficiency test reports were not available. Results and Recommendations As illustrated by the energy billing data in Figure 18 and Table 9, Lift Station 1 is the dominant energy user in the City's wastewater system. From 2008— 2010, Lift Station 1 consumed between 87% and 89%of the total energy used by all the lift stations on an annual basis (excluding Lift Station 7). For the same time period, the energy costs to operate Lift Station 1 accounted for 85%to 87%of the annual energy costs for all the lift stations (excluding Lift Station 7; by agreement, the electricity bill at Lift Station 7 is paid by the homeowners association).

However, from the above energy data, WSC recommends the following: (1) Perform a detailed energy investigation of Lift Station 1, including performing a pump efficiency test. Because Lift Station 1 is the highest energy user, a more thorough investigation of the lift station's performance and overall plant efficiency is warranted. Implementing energy efficiency improvements at Lift Station 1 has the potential to yield the greatest energy bill savings because Lift Station 1 has the largest energy use, which results from it having the largest pump capacity and the greatest run time. WSC recommends seeking available energy efficiency incentives from PG&E to support the improvements. t w w_ Figure 15 Lift Statim1 1 (2) Consult with the City's PG&E account representative about changing the PG&E rate schedule for the electric meter serving Lift Station 5. Lift Station 5 is currently on an A1P rate schedule, with an average rate of$0.40/kWh is 2010, a significantly higher rate than Lift Station 4, which is of a comparable size and operating schedule. Although the cost savings of switching to a different rate schedule may be small (e.g. Al rate schedule), it is worth investigating as it could lead to essentially "free" cost savings.

Executive In 2013,the City of Arroyo Grande contracted with RFC to conduct a Water and Wastewater Rate Study (Study)to develop a financial plan as well as design rates for the water and wastewater systems. The City's Water and Wastewater Enterprises are operating in an environment where operational costs continue to increase while debt obligations and reserve funding must be satisfied to maintain a financially healthy utility. This is not a situation that is unique to the City of Arroyo Grande, as many agencies throughout the state are faced with the need to update capital infrastructure that is necessary to continue providing water and wastewater services, adhere to new regulations and mandates, and meet service demands with limited water supplies. Ater Enterprise The City provides water services to a population of approximately 17,000. The City's main source of water includes ground and surface water. The City may also purchase surplus surface water when available.The City's water supply is crucial to provide its residents with a reliable supply of water. The current rate structure of the City consists of three components: a monthly service charge, a Lopez monthly base charge (both of which vary by meter size), and a volume charge (which is tiered for residential customers and uniform for non-residential customers).The rates of all three components are also differentiated between accounts located within and outside City limits, as shown in Tables E-2 through E-4. Table E-1 provides a summary of water accounts by meter size, with the majority of residential customers served by 5/8" and 3/4" meters.Tables E-2 and E-3 identifies the monthly service charges by meter size and Table E-4 lists the volumetric charges (also commonly referred to as commodity charges).

Page 5 Total reserves for Fiscal Year 2014-15 is estimated at approximately $6.1M, which accounts for an operating reserve equal to ninety (90) days of operating expenses, an appropriation of capital improvements equal to$500,000, and a recommended debt service reserve equal to one year of annual debt service. However, without future revenue adjustments, the Water Enterprise would need to draw on reserves to offset annual shortfalls. Commencing in Fiscal Year 2015-16, reserves would need to cover a shortfall of approximately $520,000. By Fiscal Year 2018-19, the draw on reserves would reach an amount slightly over $800,000. In addition, starting with Fiscal Year 2019-20, reserves would be $720,000 short of the recommended minimum target and would be fully depleted by Fiscal Year 2021- 22. The City also has debt obligations and corresponding bond covenants to fulfill on an annual basis. With current rate revenue,the City would not satisfy its 125% bond coverage ratio commencing in Fiscal Year 2018-19. After review of the Water Enterprise's revenue requirements, reserves, debt obligations, and current revenues, it is recommended that the City adjust revenue through a modest step up approach for Fiscal Year 2014-15 through Fiscal Year 2018-19 (1%, 2%, 3%, 3%, 3%). The proposed financial plan for the water system aims to strike a balance between the recognition of the current fiscal landscape with a multi-year measured approach. Under the proposed plan, the Water Enterprise will maintain reserves above the minimum target throughout Fiscal Year 2021-22. In order to mitigate long-term impacts to customers while maintaining the fund's finances, a "step-up" rate-adjustment approach is proposed (rather than imposing a 5%annual increase beginning in Fiscal Year 2016-17). Through our analysis, RFC reviewed the current rate structure and consumption files to determine the most appropriate rate structure to employ moving forward.As such, RFC is recommending the following proposed adjustments to the current rate structure: • RFC recommends that all accounts (whether or not they are located within City limits) be charged the same rates. Typically, differentiating rates between customers inside and outside the City is commonly employed when additional facilities are required to serve those customers, such as an additional pumping station, storage facilities, or transmission and distribution improvements. The costs associated with these facilities should then be accounted for separately to track the additional "cost of service" incurred to serve these accounts, which would justify the higher water rates in compliance with Proposition 218. The City currently only has ten (10) accounts that are outside City limits and keeping track of the facilities that serve these properties and associated costs would be tedious and require additional staff time that would not be cost effective. Therefore, it is recommended that all accounts are charged based on one rate schedule that differs by meter size and customer class. • RFC also recommends combining the monthly service charge and Lopez charge as one monthly fixed charge. Doing so would simplify the City's rate schedule for its customers and establish a fixed revenue stream that provides more flexibility to the City. Although the new recommended fixed charge still includes costs associated with the Lopez Water Supply, it is not a separate charge that appears to be solely designated for the Lopez Water Supply. The City should still maintain its separate fund for Lopez (Fund 641) and only transfer the amount necessary to meet the annual obligation each year. The remaining revenue from the monthly fixed charge would be used for other fixed charges and the build-up of reserves within the Water Operating Fund (Fund 640). .................... _, .,. , , . Page 6 • Lastly, RFC recommends changing the City's current water rate structure from a 4-tiered rate structure to a 3-tiered rate structure. In reviewing the consumption files and analyzing the amount of consumption by tier for residential customers, only 4% of total annual consumption falls within Tier 4 as shown on Table E-5 and E-6 for Single-Family Residential (SFR) and Multi-Family Residential (MFR), respectively. Table :Single-Family Resi a is rre nt Annual Usage by Tier(ccf) MMMW Tier 1 12 12 358,907 44% Tier 2 20 32 307,365 37% .Tier 3 .... 32 64 a,„ ..,w„��.� .... ,.,. . -M,....... 64 122,780 15% 4 Tier >64 N/A 32, 4% ,..m. .M......w.. 281 Table E-6: Multi-Family Residential i (ccf) a Tier 1 12 12 88 846 86% Tier 2 6 18 -. 8067 8% ...

Setting water allotments for three tiers more closely reflects the water demand of residential customers for indoor needs (Tier 1), outdoor needs (Tier 2), and any additional usage above Tiers 1 and 2 (Tier 3). In analyzing the usage characteristics of residential customers, usage in the winter was used as a proxy to determine the indoor demand of customers as outdoor usage during the winter season is typically reduced to a negligible amount. As such, usage per account in January and February of 2012 equaled approximately 15 units of water, which reflects 75 gallons per capita per day. Similar to using winter usage to determine indoor water demand, peak residential usage in the summer can be used to determine the water demand for outdoor needs as peaking is primarily as result of increased irrigation. Summer usage averaged approximately 32 units of water per account. Because usage varies from month to month and between accounts, a buffer is recommended when setting allotments for each Tier. Consequently, it is recommended that for SFR, Tier 1 be set at 18 units to capture residential indoor water demand and Tier 2 be set at an additional 18 units of water for a total allotment of 36 units, which captures the average usage in summer of 32 units. MFR customers would be a similar structure; however, MFR customers typically do not have the same amount of outdoor water demand when compared to SFR properties. As a result, it is recommended Tier 1 would be the same allotment, but Tier 2 would be 9 units instead of 18 units. These allotments are on a per unit basis.As such, a three-unit complex would have a tier 1 allotment equal to 54 units and an additional Tier 2 allotment of 27 units of water. Non-residential and irrigation accounts would still be charged a uniform rate consistent with the current rate structure. �,... a ®.

As a result, the City has been able to build healthy fund balance for operations and capital repair & replacement expenditures. Therefore, it is recommended that the City maintain its current wastewater rate schedule, as increases are not necessary at this time. We recommend that the City periodically review the Wastewater Enterprise to determine if adjustments are needed at a later date, but at this point, and based on the current revenue requirements, revenue adjustments are not necessary. �n,n _................. _ — Page 8 1 Assumptions Used in the Study The period for the Water and Wastewater Financial Plan Study is for Fiscal Year 2013-14 through Fiscal Year 2022-23.z Various types of assumptions and inputs were incorporated into the Study.

Page 9 2 Water System - Financial Plan and Rates 2.1 Financial Plan 2.1.1 Revenue Requirements A review of a utility's revenue requirements is a key step in the rate design process. The review involves analyses of annual operating revenues under the current rates, operation and maintenance (O&M) expenses, capital expenditures, transfers between funds, and reserve requirements.This section of the report provides a discussion on projected revenues, O&M and capital expenditures, the capital improvement financing plan, debt service requirements, and revenue adjustments required to ensure the fiscal sustainability of the Water Enterprise. 2.1.1.1 Revenuesfrom Current ores The current water rate structure consists of three components: a monthly service charge, a Lopez monthly base charge (both of which vary by meter size), and a volume charge (which is tiered for residential customers and uniform for non-residential customers).The projected water revenues for the Water Enterprise derived from current rates are shown in Table 2-1.

Table 2-3 shows the most recent 5-year CIP from the City. The Water Enterprise's future CIP needs will be funded through proposed rates on a Pay-As-You-Go basis (PAYGO), as the City currently does not anticipate the use of debt-financing. Therefore, no debt is proposed to fund CIP for the Water Enterprise. -.. ._ Page 10 Table ter Capital Expenditures a.

Currently,the City has an Operating Reserve equal to 60 days of the Water Enterprise's annual 0&M expenses plus$500,000 for ongoing capital.The following is the recommended reserves to maintain for the Water Enterprise Fund. Operating Reserve — The operating reserve is used primarily to meet ongoing cash flow requirements. Given that a majority of the City's water revenue is through its commodity charge (63% of revenue), RFC recommends increasing the operating reserve target from 60 days to 90-days of O&M expenses. As the potential of revenue volatility increases, reserves should be set at an amount to offset this revenue reliability. A 90-day reserve ensures working capital to support the operation, maintenance and administration of the utility. Maintaining this level of reserves also provides liquid funds for the continued ongoing operations of the utility in the event of unforeseen costs or interruption with the utility or the bi-monthly billing system. Capital Reserve — Based on the expected cost of the City's future CIP expenditure, RFC recommends maintaining a minimum capital reserve at the current amount of$500,000. Debt Service Reserve— Based on the outstanding debt obligation of the City for the Lopez Water Supply, it is recommended that the City establish a debt serve reserve equal to 1-year of annual debt (approximately $1.4M). This debt is not only an ongoing obligation, but it also funds the primary water source of the City. As such,the Lopez Water Supply is a critical asset of the City and establishing a reserve as security will ensure sufficient bond coverage and potentially mitigate future revenue increases caused by new projects associated with the Lopez Dam. The reserve can also be drawn upon during times of reduced consumption without affecting operations or scheduled capital improvement projects. Collectively, total minimum reserve target of the Water Utility would equal approximately $3.2M,which reflects approximately 220 days of liquid equity. __ — _ -- Page 11 2.1.1.5 Financial Pro Forma at Current Rates Table 2-4 displays a summary pro forma of the Water Enterprise's funds under current rates over the forecast period (Appendix "A" provides a detailed summary of Table 2-4). All projections shown in the table are based on the current rate structure and do not include any revenue adjustments. Under this scenario, revenues generated from rates and other miscellaneous revenues are slightly less than operating expenses of the Water Enterprise for Fiscal Year 2014-15; however, as 0&M costs increase through annual inflationary adjustments, current revenues cannot fully fund C&M, capital, and debt obligations without drawing down reserves each year. Commencing in Fiscal Year 2015-16, reserves would need to cover a shortfall of approximately $520,000. By Fiscal Year 2018-19, the draw on reserves would reach an amount slightly over$800,000. In addition, starting with Fiscal Year 2019-20, reserves would be $720,000 short of the recommended minimum target and would be fully depleted by Fiscal Year 2021-22. In addition, the City currently has debt obligations and corresponding bond covenants to fulfill on an annual basis. With current rate revenue, the City would not satisfy its 125% bond coverage ratio commencing in Fiscal Year 2018-19. In conclusion, the City will likely be unable to maintain fiscal sustainability and solvency under the current rates.

These proposed revenue adjustments would occur on July 1st for each year of the five years, commencing on July 1, 2014. The proposed revenue adjustments would enable the Enterprise to complete the planned capital projects for the Study period while maintain reserves above the Enterprise's recommended minimum reserve levels. The proposed adjustments also allow the City to maintain compliance with its bond covenant of 125 percent coverage through the planning horizon. ®1,282 Proposed Financial A pro forma of the proposed revenue requirements is shown in Table 2-5 below (Appendix "B" provides a detailed summary of Table 2-5). The proposed revenue requirements account for the City's financial needs, meeting target reserve balances and achieving positive net revenues through the study period while addressing the City's O&M and CIP needs. Additionally, the Water Enterprise will satisfy its debt reserve requirement of 125% in future years.

A property-related charge (such as water rates) imposed by a public agency on a parcel shall not exceed the funds required to provide the property related service. 2. Revenues derived by the charge shall not be used for any other purpose other than that for which the charge was imposed. 3. The amount of the charge imposed upon any parcel shall not exceed the proportional cost of service attributable to the parcel. 4. No charge may be imposed for a service unless that service is actually used or immediately available to the owner of property. 5. A written notice of the proposed charge shall be mailed to the record owner of each parcel at least 45 days prior to the public hearing,when the agency considers all written protests against the charge. Prop 218 ensures that Water Rates cannot be "arbitrary and capricious," meaning that the rate- setting methodology must be sound and that there must be a nexus between costs and the rate charge. In the Rate Methodology, RFC ensures that all aspects of Proposition 218 are followed and that it creates rates that charge customers equitably. In addition, as stated in the American Water Works Association (AWWA) Manual M1, "the costs of water rates and charges should be recovered from classes of customers in proportion to the cost of serving those customers." In conjunction with Proposition 218, Article X (2) of the State Constitution established the need to preserve the State's water supplies and to discourage the wasteful or unreasonable use of water by encouraging conservation. In addition,Section 106 of the Water Code declares that the highest use of water is for domestic purposes, and irrigation is secondary. In connection with meeting the objectives of Article X, Water Code Sections 370 (AB2882) and 375 authorize a water purveyor to utilize its water rate design to incentivize the efficient use of water. Although incentives to conserve water could be provided by implementing a higher rate for water as consumption increases, a nexus between rates and cost incurred to provide water at those rates must be developed to achieve compliance with Proposition 218. For this analysis, consumption and peaking characteristics of customers as well as available water supplies of the City were analyzed to appropriately allocate costs between customer classes. Variable costs were separated into two discrete components (base and peak costs) to reflect the cost incurred by the Water Utility. Furthermore, for residential customers, costs were further apportioned between defined tiers to determine the proportional share of cost incurred by such tier. This approach synchronizes the objectives of Article X (2) and Proposition 218 in developing a cost of service tiered rate structure. ®,�.e ...__ .___,. ___,. _ e Page 16 2.2.2 Rate Methodology The enterprise's revenue requirements are, by definition,the cost of providing service. This cost is then used as the basis to develop unit costs for the water components and to allocate costs to the various customer classes in proportion to the water services rendered. The concept of proportionate allocation to customer classes requires that allocations should consider not only the average quantity of water used but also the peak rate at which it is consumed. This is because the water system is designed to handle peak demands, and the additional costs associated with design, construction and maintenance of facilities specified to meet these peak demands need to be allocated to those incurring such costs so that the costs can be recovered appropriately. This study calculated water rates based on Fiscal Year 2013-14 as the base year for the new rates to be proposed. The annual revenue requirements or costs of service to be recovered from rates include C&M expenses, debt service and coverage, water supply, capital costs, and funding of reserves. O&M expenses include costs directly related to the supply, treatment, and distribution of water as well as routine maintenance of system facilities. The total Fiscal Year 2014-15 cost of service to be recovered through rates from the water enterprise's customers, shown in Table 2-6 on the following page, is estimated at approximately $65M. The cost of service analysis is based upon the premise that the utility must generate annual revenues adequate to meet the estimated annual revenue requirements. To allocate the cost of service among the different customer classes, costs first need to be allocated to the appropriate water cost components. The following section describes the allocation of the operating and capital costs of service to the appropriate parameters of the water system. .2.3 Functional Cost Components The total cost of water service is analyzed by system function in order to equitably distribute costs of service to the various classes of customers. For this analysis, water utility costs of service are assigned under the Base-Extra Capacity method to three basic functional cost components: base costs, extra capacity or peaking costs, and customer service-related costs. This method is consistent with the American Water Works Association M1 Manual, and is widely used in the water industry to design rates for retail customers. Table 2-6 shows a summary by function for each year of the five-year study period, and Table 2-7 provides a breakdown of the City's revenue requirements by functional cost components, using a ten-year annual average to account for how costs are incurred overtime. me �..

Customer costs include such costs as meter reading, billing, collecting, and accounting. Meter service costs include maintenance and capital costs associated with meters and a portion of the capacity related costs. Proposition 218 requires a nexus between the rates and costs of providing service. To meet this requirement, RFC has conducted cost of service analysis and has identified two different rate components of the commodity rates which include delivery and peaking costs. DELIVERY COSTS Delivery costs, also commonly referred to as Base costs, are those operating and capital costs of the water system associated with delivering water to all customers at a constant average rate of use. Therefore, delivery costs are spread over all units of water, irrespective of customer classes or tiers,to calculate a uniform rate. Ex-rRA CAPACITY COSTS Extra capacity or peaking costs represent those costs incurred to meet customer peak demands for water in excess of a baseline usage. Total extra capacity costs are apportioned between maximum day and maximum hour demands based on the type of expense. The maximum day demand is the maximum amount of water used in a single day in a year. The maximum hour demand is the maximum usage in an hour on the maximum usage day. Different facilities are designed to meet different peaking characteristics. Therefore, extra capacity costs include capital improvements and power related costs, and have been apportioned between base, maximum day, and maximum hour. Costs allocated to base are part of the delivery costs as defined above. 2.2.4 Proposed Rate Structure FIXED CHARGES Customer service costs include customer-related and meter-related costs. Customer costs are uniform for all customers and include such costs as meter reading, billing, collecting and accounting, and fire protection for 840 public fire hydrants (reference is made to Appendix "C" for cost allocation between hydrant and private fire lines). Currently, the City's fixed monthly water charge generates approximately 37% of total revenue and as part of the new rate structure; RFC maintained a similar percentage of revenue from the fixed monthly charge to maintain the current level of revenue stability (37% Fixed/63%Variable). --- --- Page 19 Meter service costs include maintenance and capital costs associated with meters and a portion of the capacity related costs. RFC utilized the American Water Works Association meter service cost ratios in calculating the meter component of the fixed charge. These costs are assigned based on meter size. Based on these ratios, the City's 6,340 accounts have a meter equivalency of 6,937. Table 2-8 shows the fixed charge separated between costs apportioned evenly over all units and meter equivalencies. Table 2-9 shows the proposed Fiscal Year 2014-15 monthly charge by meter size, and Table 2-10A shows the proposed five-year monthly service charges. The total proposed meter charge includes both the billing and customer service charge and the meter component charge. Table 2-10B shows the proposed five-year monthly service charges for Private Fire Lines by size of connection.

Variable costs include base and peaking. Base costs are apportioned over total applicable billable units regardless of customer class, which include costs such as water treatment services and chemicals. As such, base costs are divided by all units of water. Doing so derives a base cost per unit of water. Costs associated with peaking, which primarily includes capital improvements and power, are first apportioned to each defined customer class based on their total demand (total water used weighted by peak factor). Peaking was calculated for each customer class based on the consumption files,which ensures that accounts within each customer class will only recover the costs allocated to their respective customer class and no account is subsidizing any other account. Table 2-11 takes the variable costs for Fiscal Year 2014-15 associated with base costs to calculate a rate per unit of water and Table 2-12 shows Fiscal Year 2014-15 peak costs allocated between residential and non-residential customers. Table 2-13 is the sum of cost in Tables 2-11 and 2-12 for each distinct customer class. _� ro...... ...., m, r...... ...... .. �.

Similar to the existing rate structure, the proposed variable rates for residential customers are tiered and,for non-residential customers the rate is uniform. RESIDENTIAL RATE STRUCTURE For residential customers, the variable charges (base and peaking) are further apportioned between three distinct tiers. The goal of the first tier is to provide for basic indoor water use; the second tier to provide for outdoor irrigation; and the third tier for excessive use or to encourage conservation. This is consistent with State laws regarding the highest and most efficient use of water. Tier 1 is calculated by the base winter quarter average, equal to approximately 75 gallons per day per capita (with a city density factor of 2.45), which is used as a proxy for determining indoor usage. However, based on the analysis of usage patterns and the fluctuations in usage during the winter quarter, RFC recommends that the allotment for Tier 1 be slighted adjusted from 12 to 18 CCF per SFR & MFR unit. Tier 2 is designed to account for an additional allotment for outdoor irrigation needs of 18 CCF per SFR unit and 9 CCF per MFR unit Page 22 (which typically have less outdoor landscape area when compared to SFR). Therefore, in reviewing the consumption patterns and peak use during the summer quarter average, Tier 2 captures the average bi-monthly summer use of single family residential customers equal to approximately 32 CCF and approximately 24 CCF for a multi-family unit. Tier 3 captures any additional usage above the amount budgeted in Tiers 1 and 2. With these defined tiers and allotments, the functional variable costs are then applied to each tier. Similar to how maximum day and maximum hour costs were apportioned between customer classes, the total residential annualized variable costs (base & peak costs) in Fiscal Year 2014-15, equal to $3,229,689 for residential customers, are further apportioned between the defined tiers based on the peaking characteristics generated by customers within each tier, where Tier 1 is considered the base level (no peak; equal to 1.0). Table 2-14 calculate the rate per unit(CCF)of each Residential Tier for Fiscal Year 2014-15.

Customers other than residential vary considerably in size, use profile and needs, which makes it impractical and inequitable to place them in a "one size fits all" tiered rate structure without additional detailed data and analysis on type of business and related water demand for such business to determine appropriate allotments for efficient use. For example, a bookstore and a coffee shop exhibit drastically different water needs. However, despite not being tiered, the uniform rate structure is built on the same cost components, and the amount of Peak costs allocated to Non-residential and Irrigation is fully recovered by the customer class. Therefore, Non-Residential customers are paying their fair share of incurred costs. Table 2-18 identifies the rate per unit for Fiscal Year 2014-15 through Fiscal Year 2018-19.

This section of the report provides a discussion on projected revenues' O&M and capital expenditures, the capital improvement financing plan, debt service requirements, and revenue adjustments required to ensure the fiscal sustainability and solvency of the Wastewater Enterprise. 3.3.1.1 Revenuesfrom Current Rates The current wastewater (VVVV) rate structure consists of monthly base service charges (by dwelling unit) for all customer classes and a discharge or commodity rate per hundred cubic feet([CF). Current WW rates are shown in Tables 3'1 and 3'2.

The City's Fiscal Year 2013-14 budget values and the assumed inflation factors for the study period (as shown in Table 2-1)were used as the basis for projecting O&M costs.Table 3-5 summarizes projected O&M expenses for the wastewater enterprise. The VVVV O&M expenses are projected to increase at approximately three percent per year. Table 3-5: Projected WW O&M Expenses l,',T!otal Operating Expenditures: $960,280 $907,880 $922,137 $936,822 $951,947 $967,525 Page 28 — 3.3.1.3 Capital Improvement Plan The City has adopted a long-term capital improvement plan (CIP) to address the WW Enterprise's future needs. Table 4-5 shows the total expected CIP construction cost by year for the first five years of the ten-year study period. The figures are per the Sewer Master Plan and are adjusted for inflation. These projects will be funded through proposed rate revenues(PAYGO).There is no debt proposed to fund CIP for the WW enterprise. Table 3-6:WW CIP Adjusted For inflation m MEOW 101,111 111 Total CIP Plan: $352,290 $190,500 $246,900 $201,512 $219,427 $562,000 3.3.1.4 Reserve Requirements To ensure fiscal sustainability and the continued operation of the WW enterprise, RFC recommends that the following reserve level targets be met. Operating Reserve —The operating reserve is used primarily to meet ongoing cash flow requirements. Given that a majority of the City's wastewater revenue is through its discharge rates (75% of revenue), RFC recommends that the City increase its operating reserve target from 60 days to 90-days of O&M expenses. As the potential of revenue volatility increases, reserves should be set at an amount to offset this revenue reliability. A 90-day reserve ensures working capital to support the operation, maintenance and administration of the utility. Maintaining this level of reserves also provides liquid funds for the continued ongoing operations of the utility in the event of unforeseen costs or interruption with the utility or the bi-monthly billing system. Capital Reserve — Based on the relatively low expected cost of the City's future CIP expenditure, RFC recommends that the City continues to maintain a target capital reserve level equal to 100 percent of the enterprise's expected annual CIP expenses. 3.2 Fii cf al Pro Forma Current es Table 4-6 displays the pro forma of the WW Enterprise's funds under current rates over the forecast period. All projections shown in the table are based on the current rate structure and do not include any rate adjustments or proceeds from additional debt issuances. Under this scenario, revenues generated from current rates and other miscellaneous revenues are sufficient to recover all operating expenses of the WW Enterprise.As a result, it is projected that the City will be able to maintain fiscal sustainability and solvency under their current Fiscal Year 2012-13 rates and; therefore, rate adjustments are not necessary at this point in time.As capital costs fluctuate from year-to-year, reserves are used when necessary. ____ --------- _____ Page 29 Table 3-7: Detailed Fi ial Plan Pro-forma at Current a es Revenues from Current pates Budgeted Revenue $0 Service Charges $252,324 $252,324 $252,324 $252,324 $252,324 $252,324 $252,324 $252,324 $252,324 $252,324 qdm xhop C.A. g;'6 Ytp'Pi7„N°i4 '484RDo4"nd '$8A'4$VA $844,'d94 5840&.,r4 s84'0;8144 $iG1YY„154 984D3» "y8A4,y94 51 1'51 Total Revenues from Current pates: p $1,091}478 54,092,4719 $4„092,478 $3,092,478 $%,RM%'k„+478 $1',09'4.4I8 SY UNA'.,ayp $4.01,470 $Y,p42.+tP'$p�� $1,011,144 Revenues Total Revenue from Rates $1,092,478 $1,092,478 $1,092,478 $1,092,478 $1,092,478 $1,092,478 $1,092,478 $1,092,478 $1,092,478 $1,092,478 Other Operating Revenues $16,000 $16,000 $16,000 $16,000 $16,000 $16,000 $16,000 $16,000 $16,000 $16,000 Total Operating Revenues $1,108,478 $1,108,478 $1,108,478 $1, 8,478...$1,108,478 __$1,308,476 $1,108,478 $1,108,476 $1,108,478 $1,108,478 10 Expenditures Total Operating Expenditures $276,380 $295,580 $294,122 $302,921 $311,982 $321,315 $330,928 $340,828 $351,024 $361,526 Net Revenues Prior to Debt Payment $832,098 $822,898 SB14,356 $805,557 $796,496 $787,163 $777,550 $767,650 $757,454 $746,951 Non-Operating Expenditures Existing Debt Service $21,000 $21,000 $21,000 $21,000 $21,000 $21,Boo $21,000 $21,000 $21,000 $21,000 Proposed Debt Service $0 $0 $0 $0 $0 $0 $0 $0 $0 $0 Total Nan-Operating Expenditures $21,000 $21,000 $21,000 $21,000 $21,000 $2_1,000 $21,OOD $21,000................521,000 $21,000• Net Revenues after Debt Payment $811,098 $801,898 $793,356 $784,557 $775,496 $766,163 $756,550 $746,650 $736,454 $725,951 Operating Reserve Balances Beginning Balances $670,013 $697,021 $965,679 $956,262 $1,069,909 $1,142,648 $949,130 $817,620 $971,586 $914,674 Transfer Out-Personnel ($288,500) ($293,840) ($302,655) ($311,735) ($321,087) ($330,720) ($340,641) ($350,860) ($361,386) ($372,228) Transfer Out-Operating ($69,000) ($72,5001 ($74,675) ($76,915) ($79,223) ($81,599) ($84,047) ($86,569) ($89,166) ($91,841) Transfer Out-Cast Allocation ($69,3001 ($71,400) ($73,542) ($75,748) ($78,021) ($00,361) ($82,772) ($85,255) ($87,813) ($90,447) Transfer Out-USDA City Hall Loan ($5,0D0) ($5,000) ($5,000) ($5,000) ($5,000) ($5,000) ($5,000) ($51000) ($5,000) ($5,000) �n Emu n ld 311 4....�$��.��.� 9fiLo�f�r �r� 9$W'�L i$�� ( c��g�� &�xi�,�_6� 11�v'r_ Net Income(too)after Transfers $27,008 $160,658 $90,583 $113,647 $72,738 ($293,517) ($31,510) $153,966 ($56,911) $111,436 Ending Balances $697,021 $965,679 $956,262 $1,069,909 $1,142,648 $849,130 $817,620 $971,586 $914,674 $1,026,110 Target Balances(%of Operating Expenditure plus CIP) $675,795 $680,830 $686,249 $691,830 $697,578 $703,499 $709,597 $715,878 $722,347 $729,011 Debt Coverage N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A 3.3.3 Recommendations and se d Financi 3.3.3.1 Proposed Revenue Adjustments The WW Enterprise is currently financial solvent and it is recommended that the City maintain the current rate structure.The financial plan illustrates the Wastewater Enterprise will be financial solvent for the next five years and on; therefore no revenue adjustments are required. Figures 3-1, 3-2, and 3-3 illustrate the projected five-year financial plan for the Wastewater Enterprise. Figure 3-1 illustrates the operating position of the Wastewater Enterprise, where the expenses, inclusive of reserve funding, are shown by stacked bars and total revenue at current rates is shown by the horizontal trend line. Figure 3-2 summarizes the projected CIP and its funding sources of 100% PAYGO. There is no debt shown because the proposed financial plan does not propose debt.

Although capital costs in Fiscal Year 2018-19 exceed the annual revenue, the enterprise has adequate reserves to fund the necessary capital and is replenished in subsequent years. As such, a Proposition 218 noticing is not required for the City's Wastewater Enterprise as the current rates provide sufficient funding for costs incurred and reserves. .. _. _ Page 32 ..............

Sewer System Management Plan—Revision 01 Element 5—Design and Performance Standards Element 5 - Design and Performance Standards This section describes existing City standards that are in place and the process for revising them. It also covers compliance inspection standards that are existing and in use. Element 5 — Design & Standards Appendix • There is no Appendix for Element 5. 5.1 Regulatory Requirements The SSMP must identify design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems. The SSMP must identify the procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects. 5.2 Design and Construction Standards The purpose of the Standards and Specifications is to provide minimum standards for the design, types and uses of materials, and the preparation of plans for construction, repair, or alteration of City sewer and water facilities. The following sections, from the City Municipal Code, address the standards expected by the City for conducting repairs or new construction related to the sewer system. ■ Chapter 13.12 Sewer Service System Section 13.12.120 —Sewer connections--Applications Section 13.12.130 — Private systems—Construction--Inspections Section 13.12.270 — Inspection required In particular, the City requires the use of the California Uniform Plumbing Code (UPC) and permits must be obtained prior to construction. All work must be completed based upon the UPC and alterations must be approved by the Director. If it is ever determined that the City's adopted Standards and Specifications are insufficient, the standards and specifications used will be those of the "Standard Specifications for Public Works Construction" also known as "the Green Book". 5.3 Inspection Standards The City's standard public works procedure requires work to be placed into service only after it is accepted by the Utilities Supervisor following satisfactory inspection and testing. The City provides continuous inspection during the construction of sewer facilities and believes that proper installation is the key to ensuring proper operation and maximum life expectancy.

All SSO's shall be reported in accordance with the California Water Code, other State Laws, other applicable RWQCB WDR, and/or permit requirements. The SSMP identifies the officials who will receive immediate notification; 4. Procedures to ensure that appropriate Staff and contractor personnel are aware of and follow the OERP and are appropriately trained; 5. Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and 6. A program to ensure that all reasonable steps are taken to contain untreated wastewater and prevent discharge of untreated wastewater to waters of the State. The program also must define steps to minimize and correct any adverse impact on the environment resulting from the SSO, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. City of Arroyo Grande SSMP Page 6-1 Sewer System Management Plan—Revision 01 Element 6—Sewer System Management Plan OERP 6.2 SSO Response Staff is on-call twenty-four (24) hours per day, seven (7) days per week. The goal for responding to an SSO during business hours is 15 minutes from receipt of call. During non-business hours, the City's goal for responding to a SSO is 30 minutes. The City has invested in Supervisory Control and Data Acquisition (SCADA) which allows for constant monitoring of Lift Station wet wells. This feature dispatches maintenance staff to the problem before there is a high level in the well and the potential for a spill. Staff can also review the performance of each facility via SCADA prior to responding to determine how serious the problem is and how heavy the flow is, so that a vacuum truck can be dispatched if necessary. City of Arroyo Grande operations, maintenance, and emergency response activities are funded annually through an adopted budget. Staff maintains all equipment necessary to maintain the sewer collection and conveyance system and respond to SSOs. Examples of this equipment are; Vactor Truck, sewer bypass pumps, service crane trucks, and spill containment materials. The City's policy is to respond to all spills within the City service area boundary and provide mutual aid outside the City boundary, whether on public or private property and to take all steps possible to prevent the spills from reaching the storm drains, flood control channels, or waters of the State. The City is enrolled in a mutual aid agreement for assistance with emergency response activities. Contact information for enrolled members can be found at www.calwarn.oLq. The City identified Emergency Operating Procedures (EOPs) to be developed for emergency response to SSOs to help ensure appropriate response to all SSOs. These procedures are planned to completed and implemented by the end of 2015 Element 2 of this SSMP addresses the organizational structure and responsibilities of City staff. City EOPs will also discuss roles and responsibilities for SSO response activities. The lines of authority during an emergency are shown in Figure 6-1.

The call receiver (Public Works, Utilities Supervisor, Accounting Clerk, Answering Service, or 911 Operator) will obtain the location from the contact and any description they may have of the problem. Additionally, they will obtain the contact's name, phone number, and additional information as indicated on the SSO Response Field Checklist for follow-up information. SSO Response Field Checklist and Active Spill Estimate Worksheet are located in Appendix 6. 2. The call receiver will contact the on-duty staff by phone immediately and direct the operator to the described location. 3. The on-duty staff is to contact the supervisor and request appropriate support. The on- duty staff is to keep the administrative staff informed of progress as necessary. 4. Administrative Staff to notify Public Works Director, City Manager, Mayor and other City representatives as necessary and appropriate. 5. Utilities Supervisor or Public Works Director to notify all appropriate public agencies as necessary. SSO Notification Procedure SSO notification procedures vary based on whether the SSO is classified as a Category 1, Category 2, Category 3, or PLSD. After notifying the RWQCB of any SSO, the Utilities Supervisor or their designee should email RWQCB Staff, Katie DiSimone: kdisimone @waterboards.ca.gov to confirm that the report was submitted and received. Category 1 SSOs For any discharges of sewage that result in a discharge to a drainage channel or a surface water or to the City storm drain system and is not fully captured and returned to the sewer system or disposed of properly, the City shall, as soon as possible, but no later than two (2) hours after becoming aware of the discharge, notify the California Governor's Office of Emergency Services (Cal OES) at 1-800-852-7550. Category 2 SSOs For a SSO 1,000 gallons or greater in volume that does not discharge to a drainage channel or surface water, the Utilities Supervisor or their designee may email RWQCB Staff, Katie DiSimone, at kdisimone @waterboards.ca.gov to notify her of the SSO within 3 business days after becoming aware of the SSO. Category 3 SSOs If a SSO occurs due to a problem in the City's sanitary sewer collection system and does not reach a drainage channel, surface water, the City storm drain system, or is fully captured from the County storm drain system and returned to the sewer system or disposed of properly and is less than 1000 gallons in volume, the Utilities Supervisor or City of Arroyo Grande SSMP Page 6-4 Sewer System Management Plan—Revision 01 Element 6—Sewer System Management Plan OERP their designee may email RWQCB Staff, Katie DiSimone, at kdisimone @waterboards.ca.gov to notify her of the SSO within 30 calendar days after the end of the calendar month in which the SSO occurred. PLSDs The City may voluntarily notify regulatory agencies, such as the RWQCB, of a private lateral sewage discharge (PLSD). SWRCB encourages notifying Cal OES of a PLSD if the PLSD is greater than or equal to 1,000 gallons with the potential to reach surface water. SWRCB also encourages notifying the appropriate regulatory agencies (see list of potential agencies in Element 2: Organization) or notifying the responsible party that notification and reporting should be completed as required by Health and Safety Code Section 5410 et. seq. and Water Code Section 13271 if the PLSD is greater than or equal to 1,000 gallons regardless of the SSO destination. 6. Upon completion of containment and clean-up, Utilities Supervisor or their designee to complete report, as required, to RWQCB and any other required agencies (as described in Section 6 above). 7. Public Works Maintenance staff will fill out the SSO Response Field Checklist in its entirety and forward this document to the Utilities Supervisor or their designee for submission into CIWQS database. Staff will upload data within the required timeframes and assign an SSO event ID number. This ID number shall be placed on the form and documented in the program files. Copies of this document/ID number shall be returned to the City offices for record keeping along with all other spill documentation.

If CIWQS is not available, the required information must be faxed to RWQCB at (805) 543-0397. 6.3.5 PLSDs PLSDs may be voluntarily reported in CIWQS. SWRCB encourages reporting a PLSD in CIWQS or notifying the responsible party that notification and reporting should be completed as required by Health and Safety Code Section 5410 et. seq. and Water Code Section 13271 if the PLSD is greater than or equal to 1,000 gallons regardless of the SSO destination. If a PLSD is reported in CIWQS, the City must identify the SSO as occurring and caused by a private lateral, and a responsible party, who is not the City, should be identified, if known. Certification of PLSD reports is not required. 6.3.6 No Spill Certification If there are no SSOs during a calendar month, the City must certify a "No Spill" certification in CIWQS within thirty (30) calendar days after the end the calendar month in which no SSO occurred. If CIWQS is not available, the required information must be faxed to RWQCB at (805) 543-0397. If there are no SSOs during a calendar month, but the City reported a PLSD, the City shall certify a "No Spill" certification statement for that month. 6.3.7 Amended SSO Reports If the City wishes to update or add additional information to a certified SOS report, the City must complete this update or addition by amending the SSO report or adding an attachment to the SSO report in CIWQS within 120 calendar days after the SSO end date. If a SSO report needs to be amended after this 120 calendar day deadline, the City may contact the SSO Program Manager, Russell Norman, at Russell.Norman @waterboards.ca.gov and request to amend the SSO report. The City is required to submit justification for why the additional information was not available prior to the end of the 120 calendar day deadline with this request. 6.4 SSO Impact Mitigation The initial response to an SSO includes a service truck with traffic control equipment as well as equipment to cordon off the site from the public. The Police department is available as needed for site security. Operations Staff takes all reasonable steps to contain sewage and to prevent sewage discharges to surface waters. Upon arrival Operations Staff will determine the cause of the SSO and, utilizing the spill kit, will dike or sandbag off any drain inlets that flow to surface water bodies or to gutters. The City may use the storm drain system as a containment device if needed. The outlet to the storm drain is blocked and the spill and wash down water are then vacuumed from the line. In the event that the SSO comes into contact with surface water bodies, testing of those bodies will be completed to determine the level of contamination and the appropriate method of clean up. City of Arroyo Grande SSMP Page 6-8 Sewer System Management Plan—Revision 01 Element 6—Sewer System Management Plan OERP Based upon the location and type of overflow, operations Staff respond with appropriate equipment. On observation of the spill an estimate of gallons per minute will be made and a SSO Response Field Report will be completed. Equipment used may include a Vactor truck, a service truck equipped with traffic control devices, and the necessary containment tools. Containment tools include a spill kit, sandbags and plastic tarps. All drain inlets shall be covered with visqueen, plugs, or other barriers. Additional resources are available locally from other jurisdictions or through equipment rental agencies as the situation warrants. After the spill is contained, staff will then work to begin removing the main stoppage with the Vactor and return normal flow to the system. Cleanup of raw sewage is begun at the same time with vacuuming up the water and any solid material. Containment is followed by fresh water wash down (per San Luis Obispo County request). The Utilities Supervisor and/or Public Works Director are responsible for mitigation, documentation, most reporting, and follow-up. The City currently takes all reasonable steps to contain sewage and prevent sewage discharges to surface waters and minimize or correct any adverse impacts on the environment resulting from the SSO, including accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. For mitigation purposes the Environmental Health (EH) Department provides City assistance in post-SSO monitoring. In the event of a spill, the EH Department is notified immediately along with other applicable agencies. The City then utilizes the EH Department for the service of monitoring water quality post-SSO. The City will also provide any necessary support, equipment, or Staff as requested to assist in the water quality monitoring. 6.5 Emergency Operating Procedures Emergency Operating Procedures (EOPs) are being developed in 2015 as part of the City's Overflow Emergency Response Plan (OERP). These procedures are developed to establish a standardized and appropriate response to SSOs within the City and establish compliance with the SSWDRs and will be completed and implemented by the end of 2015. The following EOPs will be included with this OERP: SS-EOP-1: Emergency Overflow Response Plan SS-EOP-2: SSO Regulatory Notification and Reporting Requirements SS-EOP-3: SSO Response Documentation SS-EOP-4: SSO Traffic and Crowd Control SS-EOP-5: SSO Volume Estimation SS-EOP-6: SSO Mitigation and Cleanup SS-EOP-7: SSO Water Quality Monitoring Arroyo Grande Creek SS-EOP-8: SSO Waterbody Closure SS-EOP-9: SSO Records Requirements SS-EOP-10: SSO Training Requirements 6.6 OERP Training The City's training plan will require staff to be trained on these procedures and the Overflow Emergency Response Plan annually. Additional training will be conducted as necessary when; new staff is introduced to the City's system, when changes are made to EOPs or the OERP, and when new equipment impacts the performance of these procedures City of Arroyo Grande SSMP Page 6-9 Sewer System Management Plan—Revision 01 Element 6—Sewer System Management Plan OERP The City's authorized representatives in wastewater operations and collection system matters are the Utilities Supervisor, Public Works Director, and City Manager. The Utilities Supervisor and Public Works Director are the Legally Responsible Officials (LRO) at this time to certify electronic spill reports submitted via the State-wide database, CIWQS. The Public Works Office Assistant is also authorized to submit SSO reports as a Data Submitter.

As of 2014 approximately 60 facilities are enrolled in the FOG Program. The City remains very proactive in addressing its High Maintenance Areas (HMA) attributed to grease that have a history of minor blockages created by these substances. The City is very proud of its successful program. The City takes this program very seriously and is entering its eighth year of program implementation. Element 7 Operations and Maintenance Appendix Supporting information for Element 7 is located at the end of this section in Appendices 7 and contains the following documents: • List of Food Service Establishments (FSE) 2014 • FOG Inspection Form • FOG Permit Application • Public Outreach Materials for both residential and commercial customers • Grease Hauling and Rendering Companies List • Cleaning Log for Use by FSE 7.1 Regulatory Requirements The FOG source control program includes the following as appropriate: • An implementation plan and schedule for public education outreach program that promotes proper disposal of FOG. • An Ordinance establishing the legal authority of the District to prohibit FOG discharges to the system and identifies measures to prevent SSOs and blockages caused by FOG. • Requirements to install grease removal devices (such as traps or interceptors); the development of design standards for such devices, maintenance requirements, Best Management Practices (BMP) requirements; and record keeping and reporting requirements. • Establishes authority to inspect grease producing facilities and assesses whether the District has sufficient Staff to inspect and enforce the FOG ordinance. • An identification of sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section, • Development and implementation of source control measures for all sources of FOG discharged to the sewer system. 7.2 FOG Control Program Outreach The City's FOG Program outreach began in 2007 and it remains a major component of the SSMP program. Prior to program "kick off' the City, in partnership with South San Luis Obispo County Sanitation District (SSLOCSD), worked to inform FSEs of the FOG Program and its requirements. FOG information flyers were mailed to each FSE. Following the distribution of the flyers; FSE surveys and personal phone calls were made to each owner or manger of the facility. This allowed each affected party to ask questions and receive information regarding the FOG Program prior to any inspection of the facility. City of Arroyo Grande SSMP Page 7-1 Sewer System Management Plan—Revision 01 Element 7—Fats, Oils&Grease Control (FOG) Program The City has made available the following items to each facility within the city: • Best Management Practices (BMP) Booklet and training • Grease Hauler List • Cleaning Record Form (English and Spanish), • No Grease Poster Inspectors have these items available when an FSE is inspected. The cost of the program is included in the sewer rates. At this time permitting and inspection require no additional fees. Residential outreach is also an important element for reducing the amount of FOG entering the collection system. While requiring grease traps and interceptors is not possible to the residential community, education is. The City of Arroyo Grande is in the process of implementing a residential outreach program through the City's Newspaper, Stagecoach Express. In addition staff has developed door-hangers to place in High maintenance Areas (HMA). Specifically, a HMA area or "trouble spot" is an area that has identified FOG discharges that go directly to a lift station. Once the flyers have been distributed, the affected lift station is closely monitored for grease reductions to measure flyer outreach success. Newspaper articles may involve multiple sewer fund topics in addition to fats, oils and grease in order to provide public education in an economically feasible manner. The City's Newspaper Articles occur as an ongoing process as needed. 7.3 FOG Control Program Discussion The City of Arroyo Grande developed a FOG Inspection Program in July 2007 and utilizes the South San Luis Obispo County Sanitation District FOG Ordinance. This ordinance establishes the regulations and requirements governing the protection of the sewer system from fats, oils and grease. The goals of the FOG Control Program are to reduce the amount of fat, oils, and grease entering the sewer system, inspect all food service establishments for FOG violations, provide education to FSEs and reduce maintenance costs from grease related problems. Doing so should reduce the risk of Sanitary Sewer Overflows and increase the longevity of the sewer collection lines. The City's FOG Control Program meets all the guidelines required by the State and Regional Water Quality Control Board and includes following: • Restaurants and food service establishments (FSEs) that generate grease are required to obtain a Source Control/FOG Permit. • FSEs are inspected at a minimum of twice per year. FSEs may be inspected more frequently as determined by the City and/or as warranted by current program compliance and past history. • All FSEs are required to use best management practices (BMP) to reduce grease discharged to the sewer system (e.g.; store waste grease in barrels to haul off site, scrape remaining food off plates and into trash receptacle before washing). • Any FSE planning a remodel is required to include installation of a grease trap/interceptor. City of Arroyo Grande SSMP Page 7-2 Sewer System Management Plan—Revision 01 Element 7—Fats, Oils&Grease Control (FOG) Program • All new FSE construction will require installation of a grease trap/interceptor, regardless of size (type of foods produced may negate the need for trap installation; a variance will be issued in lieu of permit for trap installation). • Exemptions or variances shall be available to FSEs that do not generate grease, do not cause related sewer blockages, and/or have limited space on their property that makes it impossible to install a grease trap/interceptor. • Garbage grinders will be prohibited in all restaurants except where specifically allowed by the City. • Several options regarding program fees will be evaluated annually. Program fees are intended to help alleviate the burden of the program costs and to assist in facilitating a successful FOG Control Program. The City currently is absorbing the program and inspection costs in its General Fund. 7.4 Identification of Grease Problem Areas and Sewer Cleaning One objective of a FOG control program is the identification of trouble spots, or HMA, that are likely or prove to have grease accumulation. The City identifies potential grease problem areas by tracking locations and causes of dry weather blockages and SSO's. FOG accumulation is also documented when seen in the sewer system during a visual inspection by Closed Circuit Television (CCTV). If the specific trouble spots occur in close proximity to several restaurants or grease-producing facilities the FSEs will be considered a potential source of the FOG in the sewer and increased inspections will take place. Additionally, the identified locations will be noted in the O&M program and will be monitored for cleaning frequency requirements. The City's Maintenance Staff maintains a sewer atlas depicting each manhole location. This data is used in conjunction with cleaning logs, for which Staff will note the date and time of flushing as well as debris type and severity. Additional information about cleaning and maintenance is included in Element 4: Operations and Maintenance Program. 7.5 Legal Authority The City FOG Program is governed by the SSLOCSD FOG Control Ordinance 2008-01. This is the second Ordinance that the City will be adopting on behalf its treatment plant. This decision is being made because FOG control is an element of Pretreatment. The other Ordinance currently in use is the SSLOCSD's Pretreatment Ordinance 1994-1. The FOG Ordinance includes: • Establishment of enforcement authority • Limits on types of wastes discharged to public sewers • Requirements for specific design and construction of grease interceptors and/or traps, • Requirements for the installation of grease interceptors • Requirements for maintenance of grease interceptors, • Enforcement, and • Implementation measures, as appropriate. If the City finds that a grease interceptor or gravity separating device installed prior to the effective date of the ordinance that is incapable of adequately retaining the grease or oil in the City of Arroyo Grande SSMP Page 7-3 WN Sewer System Management Plan—Revision 01 Element 7—Fats, Oils&Grease Control (FOG) Program wastewater flow, the City shall notify the user, in writing, that an adequate interceptor or gravity separating device shall be installed within a specific, reasonable time period. This Ordinance is found in Appendix 7. 7.6 Identify HMA The City's maintenance Staff continues to identify sections of the sewer collections system subject to grease buildup and establishes a cleaning maintenance schedule for each section. The City has compiled a list of`hot spots', or HMA, within the community. These areas of concerns have been put on an increased cleaning schedule and will be monitored annually for cleaning frequency. The City tracks these "Trouble Spots" on a Sewer Atlas which is maintained at the Public Works office. 7.7 FOG Control Measures The City has implemented FOG control measures for all sources of grease and fats discharged to the sewer system. One of the elements that is provided to FSEs or other interested parties is the BMP manual. This manual helps to provide guidance and suggestions to FSEs in reducing the amount of FOG discharged. Implementing many of the simple inexpensive procedures can reduce the amount of FOG discharged by 90%. The FOG BMP Manual includes the following: • Train kitchen Staff and other employees about how they can help ensure BMPs are implemented • Post "No Grease" signs above all sinks and on the front of dishwashers • Use water temperatures less than 140° F in all sinks, especially the pre-rinse sink before the mechanical dishwasher • Recycle waste cooking oil • "Dry wipe" pots, pans, and dishware prior to dishwashing • Dispose of food waste by recycling and/or solid waste removal • Properly Maintain Grease Trap/Interceptors • Clean under-the-sink grease traps weekly, or more frequently, if needed • Clean grease interceptors routinely, at least quarterly • Keep a maintenance log (record keeping) • Cover outdoor grease and oil storage containers • Locate grease dumpsters and storage containers away from storm drain catch basins 7.8 FOG Program Funding The FOG Program is funded annually through the Sewer Fund and has been contracted out for inspection and administration purposes only. Program fees are included in the sewer rates in order to help alleviate the cost for an FSE to reach compliance. If at some time it is determined that program costs exceed maintenance reductions then the City will evaluate a fee based program. To date, program fees continue to decrease due to widespread Program compliance resulting in fewer facility re-inspections. Maintenance reductions are still under evaluation. City of Arroyo Grande SSMP Page 7-4 Sewer System Management Plan—Revision 01 Element 7—Fats, Oils&Grease Control (FOG) Program 7.9 FOG Characterization The City inspects all FSEs that are located within its jurisdiction. Each is closely evaluated to determine if the FSE is in compliance with the current regulations. Facilities that contain high fats, oils and grease menu items are inspected for properly working grease traps and/or interceptors. Facilities are also required to maintain proper documentation for each time their trap or interceptor is cleaned. These records must be maintained and be made available for a minimum of two years on-site. In some cases, if a facility does not currently maintain a grease trap or interceptor, one may be required to be installed. This is based upon current regulations. The current California Uniform Plumbing Code is closely followed for determining type and size of unit that will be required. Justification for grease trap versus interceptor installation is based upon foods served and prepared, number drains within the facility, type of dishwasher (if any), size and history of SSOs attributed to the establishment. Dye testing is also conducted when it is necessary to determine specific drainage sources. There are two types of permits issued. The first is a standard FOG Permit. A standard permit is issued to all typical FSEs that discharge FOG into the sewer system in amounts above 100 miligrams per liter (mg/1). Typically, this includes all facilities that have fryers or facilities that serve high quantities of creams, soups, meat, cheeses and dairy. The second permit is a Variance Permit. It is issued to FSEs that do not discharge high quantities of FOG. Examples of these facilities are: coffee houses, small sandwich shops or prepackaged grocery stores. Should a facility with a Variance Permit change ownership, a new variance will not be issued to the new owner. The new owner will be required to apply for a FOG permit and will be evaluated as if it is a whole new facility. If the food served or prepared by the FSE has not changed a new variance will be provided. The City will make this decision on a case-by-case basis.

An itemized list of the FSEs, locations and permits issued is located in Appendix 7. The itemized list will be updated continually to reflect any FSE additions or deletions. When an FSE is found to be in violation of the City's Ordinance the facility is re-inspected for compliance. Additionally, when Operations Staff is sent out on an emergency or they are conducting regular maintenance and identify high levels of FOG, the Environmental Compliance City of Arroyo Grande SSMP Page 7-6 00y Sewer System Management Plan—Revision 01 Element 7—Fats, Oils&Grease Control (FOG) Program Inspectors are notified. The FSE of concern is then inspected regardless of last inspection date. The FSE is informed of the reason for the inspection and if they are in violation, corrective actions are required at that time. The inspector may need to conduct a follow-up visit prior to returning the FSE to its regular facility visit schedule. Facility inspection paperwork is maintained in the Public Works office and is available electronically. All inspection forms are located in Appendix 7. The FOG Program is an ongoing process of education and compliance. The City is proud to be implementing it and is very grateful that the City's FSEs understand the need for program success. Together, the City, local businesses, and residents work to protect the collection system and the health of the environment.

Appendix 7-4: Fats, Oils and Grease ( FOG ) Best Management Practices ( BMP ) Manual n r ; f TR y Off, 4l PR What is FOG FOG is a shorthand way of saying Fats, Oils and Grease. FOG is composed of animal and vegetable fats and oils that are used to cook and prepare food. FOG should be recycled for use in other products, properly disposed of or land applied. Why is FOG a Problem? A wastewater system is similar to the human body. Wastewater flows through pipes (arteries), is pumped at pump stations (heart) and cleaned by the wastewater plant (kidneys). FOG clogs the pipes in the sewer system just blood like cholesterol clogs ® GxYgen,PAP blood arteries. This makes the pumps work harder " a and can cause them to fail, just like having a heart attack. RR� �k�T+ % 1 �A FOG can also cause 4a , r backups in your sewer lines that can send � e sewage into your home or restaurant. That is an open invitation for disease and illness. Train Your People Train and educate your kitchen staff and other employees about how - they can help follow the Best Management Practices (BMPs) once °i implemented . People are more willing to support an effort when they understand the basis for it. Conspicuously Post No Grease Signs Post these signs in restrooms, over sinks, near all floor drains, dishwashers and anywhere else where water may enter a drain to the sewer. Signs serve as a constant reminder for staff working with FOG. Use the Most Appropriate Water Temperature Use water temperature of less than 140 0 Fin all sinks, especially the pre-rinse sink ' before using a mechanical dishwasher. Temperatures in excess of 140°F will dissolve grease, but it can solidify in the sewer system as the water cools. Water from mechanical dishwashers should not be discharged through a grease trap or interceptor. Use the 3-Sink System Washing Rinsing Sanitizing Use the first sink to wash any dishware, the second sink to rinse the dishware and the third sink to sanitize with a 50- 100 ppm bleach solution or 200 ppm quaternary ammonia compound . Water temperatures in the sinks should meet the current California Health Department requirement. The system will save energy and costs as a result. Recycle Waste Cooking Oil ,r. There are many companies that specialize in taking waste cooking oil from fryers and other types of equipment and making animal feed or fuels, such as bio-diesel from it. Recycling reduces the amount of wastes that have to be disposed of as solid waste, and helps to prolong the life of any grease traps and interceptors. It also keeps the FOG out of the sewer system . Dry Wipe All Pots, Pans and Plates 0 Dees oho 0 Use a paper towel or scraper to dry wipe pots, pans, dishware and food preparation surfaces before washing. Dry wiping the FOG and food items that remain in pots, pans and dishware before washing will keep the FOG out of the grease traps and interceptors. This will result in less frequent cleaning of the grease interceptor and trap, thus resulting in lower maintenance costs. Witness Grease Interceptor Cleaning The grease hauler should pump out the interceptor or trap completely and clean the sides and any baffles. You are ultimately responsible for the FOG Control at your place of business. Witnessing the cleaning of your Trap or Interceptor will ensure the complete removal of all grease and solids. Properly Dispose of Food Waste i r Food should never be poured down the drain or into a toilet. Recycling of food wastes is the best option for a food service establishment. Recycling of food wastes will reduce solid waste disposal costs, and the need to frequently clean grease traps and interceptors. Clean Under-sink Grease Traps at Least Weekly Fk l'T' a LOCH AMD UFT Under sink traps � I i have less volume than outside F1 U1W grease Crr � g p T!i 1 interceptors but �� require W!FLES ~E ° frequent cleaning . k1L.d1 r'.I �µtl4 Weekly cleaning of the traps by the establishment's staff will reduce maintenance costs. Place recovered grease in proper disposal container. It can go in a dumpster, if it is in a closed container. Do not pour down any drains or in any toilets. Clean Grease Interceptors at Least Every Three Months TEEPTOR VENT / tPER Grease interceptors � l �� must be cleaned 4,c FLYN ' , 1Ion i'R� Rff"PLAE�tV �� fl � Jh quarterly to ensure DEME ; that the grease ` swaH accumulation does ACUMULATON not interfere with proper operation . The cleaning frequency is dependent on the type of establishment, the size of the interceptor, and the volume of flow discharged to the interceptor. Quarterly cleaning will prevent the plugging of the sewer line between the food service establishment and the sanitary sewer system . A backup will require a plumber to unplug the line and this could pose a serious health risk to workers and patrons. Keep a Maintenance Log and All Service Records The log serves as a record of the frequency and volume of cleaning the grease interceptor or trap. The record also helps the food service establishment maintain compliance with its permit, and affords any inspector the opportunity to verify compliance. Service records verify the accuracy of the log . The log can optimize the cleaning frequency in order to reduce costs. Cover Grease Containers Stored Outdoors Uncovered FOG containers can collect rainwater. Since FOG � floats, the rainwater can overflow the x.� container and flow onto the ground where it can reach the storm water system . Any discharge to the storm water system may result in adding biological or chemical demand to local receiving waters. The discharge might also result in legal penalties being imposed on the food service establishment. Locate Du m psters and FOG Containers Away From Storm Drains rA M'N 1 A release of FOG can degrade water quality in receiving streams in the area by adding biological and chemical demand to the stream . Discharging of FOG into storm drains can also result in fines and other legal actions. The further away a storm drain is from where the FOG is stored, the more time someone has to clean up any spills. BE AWARE of FOG dripping out of containers or dumpsters and clean up quickly. Use Absorbent Pads for All Spills y Absorbent pads can help to clean up grease and oil that has spilled on the ground near outdoor equipment, containers or dumpsters. The absorbent pads prevent the spill from entering the storm drain system when it rains. DO NOT use absorbent material such as "kitty litter," or saw dust since they can flow into the storm drains when it rains. Routinely Clean Exhaust Hoods If FOG escapes through the kitchen exhaust system, it can ��)lr accumulate on the roof «� of the house or restaurant and eventually start a fire or enter the storm drain when it rains. DO • Scrape excess grease into a sealed container and dispose of it in the trash or containers specifically designated for grease. • Place food scraps in waste containers or garbage bags for disposal with solid wastes, or start a compost pile; promote the use of scraping dishware prior to washing. • Place a wastebasket in the bathroom to dispose of wastes. • Promote the use of the 3 "R's" Reduce, Reuse and Recycle. DO NOT • Discharge fats, oils, and grease in concentrations that can cause an obstruction to the flow in a sewer. • Placed FOG from cooking in the kitchen or bathroom sinks or in the toilet. • Discharge butchering waste of any kind within the sewer system. • Discharge wastewater with temperatures in excess of current Health Department Regulations to any grease trap. This includes water from mechanical dishwashers that have a minimum required temperature of 180° F or above. • Discharge waste from a food waste disposal unit to any grease traps. • Discharge caustics, acids, solvents, soaps, enzymes, or other emulsifying agents into sinks that feed grease traps and/or interceptors. • Discharge fats, wax, grease or oils containing substances that will become viscous between 32° F (0° C) and 150° F (65° Q. • Utilize biological agents, chemicals, or enzymes for grease remediation without permission from the sanitary agency receiving the waste. • Clean equipment outdoors in an area where water can flow to the gutter, storm drain, or street. • Use the toilet as a wastebasket.

Element 8 — System Evaluation and Capacity Assurance Plan Appendix • There is no Appendix for Element 8. (Appendix 4-2 contains Capital Improvement Plan) 8.1 Regulatory Requirements The Agency shall prepare and implement a capital improvement plan that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include: a. Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSO's that escape the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events. b. Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and C. Capacity Enhancement Measures: The steps needed to establish a short- and long- term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. d. Schedule: The Agency shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated as required. 8.2 System Evaluation and Capacity Assurance Plan The City's Wastewater System Master Plan (Master Plan) was updated in 2012.

The following sections of this report describe these deficiencies in detail and address future additions and updates the City is required to make to its SSMP. The above list of updates is a summary and is not intended to replace the detailed deficiencies identified in the SSMP Audit Report. The recommendations of the entire SSMP Audit Report should be implemented in a reasonable time frame, such as by August 2, 2014, to ensure compliance with the SSSWDR. City of Arroyo Grande August 2, 2013 Page 8 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 1.0 Goal [SSSWDR D.13(i)] SSSWDR D.13(i) states: The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system. This will help reduce and prevent SSOs, as well as mitigate any SSOs that do occur. Section D.13(i): The 2009 SSMP includes four (4) goals, but they should be updated to be specific and measureable. City Staff works to achieve the four (4) goals and showed evidence of this work, such as work orders, SSO records, FOG records, and responses to complaints, during the SSMP Audit. Sufficiency: In Compliance Reference: 2009 SSMP, p. 8 Deficiencies: There are no deficiencies. Recommendation: The City should update its goals to be specific, to be measurable. City of Arroyo Grande August 2, 2013 Page 9 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 2.0 Organization [SSSWDR D.13(ii)] SSSWDR D.13(ii) states: The SSMP must identify: (a).The name of the responsible or authorized representative as described in Section J of this Order; (b).The names and telephone numbers for management, administrative, and maintenance positions responsible for implementing specific measures in the SSMP program. The SSMP must identify lines of authority through an organization chart or similar document with a narrative explanation; and (c).The chain of communication for reporting SSOs, from receipt of a complaint or other information, including the person responsible for reporting SSOs to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services (OES)). SSSWDR J states: All applications, reports, or information shall be signed and certified as follows: (i). All reports required by this Order and other information required by the State or Regional Water Board shall be signed and certified by a person designated, for a municipality, state, federal or other public agency, as either a principal executive officer or ranking elected official, or by a duly authorized representative of that person, as described in paragraph (ii) of this provision. (For purposes of electronic reporting, an electronic signature and accompanying certification, which is in compliance with the Online SSO database procedures, meet this certification requirement). (ii). An individual is a duly authorized representative only if: (a).The authorization is made in writing by a person described in paragraph (i) of this provision; and (b).The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity. Section D.13(ii)(a): The SSMP states that the Director of Recreation and Maintenance Services is the authorized representative for implementing the SSMP, but it should state that Shane Taylor, the Utilities Supervisor, is the responsible and authorized representative. The section above is in marginal compliance with the above requirement. See recommendations at the end of the Organization section of this report. City of Arroyo Grande August 2, 2013 Page 10 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Section D.13(ii)(b): The names and telephone numbers for management and administrative positions responsible for implementing specific measures in the SSMP program are included in SSMP Appendix B; however telephone numbers are not provided for maintenance positions responsible for implementing specific measures in the SSMP program. These phone numbers are available in the Public Works Department Staff Contact List. This list and its location should be referenced in the SSMP. The SSMP states which positions are responsible for each SSMP Element, but does not identify which City positions are responsible for implementing each SSMP Element. Wallace Group is contracted by SSLOCSD, who is contracted by the City, to manage and implement the City's Fats, Oils, and Grease (FOG) Control Program, but the names, contact information, and SSMP areas of responsibility for the Wallace Group and SSLOCSD Staff responsible for these activities are not identified. Lines of authority are presented in SSMP Appendix B, but include position titles and Staff names that are out of date since the City's restructuring and need to be updated. SSMP Element 2: Organization should be updated to provide the roles and responsibilities for the current position titles. This list of City Council Members included in SSMP Appendix B is not current and needs to be updated. The section above is in partial compliance with the above requirement. See recommendations at the end of the Organization section of this report. Section D.13(ii)(c): A chain of communication for reporting sanitary sewer overflows (SSOs) is provided in the 2009 SSMP; however, SSMP Element 2: Organization references SSMP Appendix B for the regulatory agency contact information, which is actually included in the Overflow Emergency Response Plan in SSMP Appendix E. City Staff position titles need to be updated to reflect the City's restructuring. The section above is in substantial compliance with the above requirement. See recommendations at the end of the Organization section of this report. Sufficiency: Partial Compliance Reference: 2009 SSMP, p. 9— 15 and Appendices B and E; CIWQS Facility At-A Glance Report (June 20, 2013) Deficiencies: The SSMP does not state the correct authorized representative for implementing the SSMP and does not identify which City positions are responsible for implementing each SSMP Element. City of Arroyo Grande August 2, 2013 Page 11 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report The names and telephone numbers for management and administrative positions responsible for implementing specific measures in the SSMP program are included in SSMP Appendix B; however telephone numbers are not provided or referenced for maintenance positions responsible for implementing specific measures in the SSMP program. Since the City utilizes a call-back sheet for City Maintenance Staff contact information, the SSMP should be updated to reference where the call-back sheet is posted for City Staff use. Wallace Group Staff and SSLOCSD Staff, who are responsible for implementing the City's FOG Control Program are not listed with their names and contact information. This list of City Council Members included in SSMP Appendix B is not current. The chain of communication for reporting sanitary sewer overflows (SSOs) provided in SSMP Element 2: Organization references SSMP Appendix B for the regulatory agency contact information, which is actually included in the Overflow Emergency Response Plan in SSMP Appendix E. City Staff position titles and names included in the lines of authority and SSO chain of communication do not reflect the City's recent restructuring. Recommendation: The name of the authorized representative for implementing the SSMP< needs to be updated. SSMP Element 2: Organization needs to be updated to include all of the names and telephone numbers of all City and Contract Staff responsible for implementing the SSMP, reference and identify the location of the Public Works Department Staff Contact List, identify which positions are responsible for implementing each SSMP Element, and correctly list the current City Council Members. The Chain of Communication section of SSMP Element 2: Organization needs to be updated to reflect the recent City staff restructuring. City of Arroyo Grande August 2, 2013 Page 12 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 3.0 Legal Authority [SSSWDR D.13(iii)] SSSWDR D.13(iii) states: Each Enrollee must demonstrate, through sanitary system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to: (a).Prevent illicit discharges into its sanitary sewer system (examples include 1/1, stormwater, chemical dumping, unauthorized debris and cut roots, etc.); (b).Require that sewers and connections be properly designed and constructed; (c). Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency; (d).Limit the discharge of fats, oils, and grease and other debris that may cause blockages; and (e).Enforce any violation of its sewer ordinances.

The SSMP should be updated to include be updated to include Arroyo Grande Municipal Code Section 13.12.420 – Private systems—Discharges. The section above is in substantial compliance with the above requirement. See recommendations at the end of the Legal Authority section of this report. Section D.13(iii)(b): Proper design and construction of sewers and connections are required by the City Public Works Department's Standard Plans (2005), The "Greenbook" (2003), the Uniform Plumbing Code (UPC), and the following Arroyo Grande Municipal Code Sections: ■ 13.12.110 – Groups of houses or buildings on one lot—Connections to main sewers. ■ 13.12.120 – Sewer connections—Applications. ■ 13.12.130 – Private systems—Construction—Inspections. ■ 13.12.140 –Approval—Required. ■ 13.12.150 –Approval—Process. ■ 13.12.270 – Inspection required. ■ 13.12.370 – Sewer pumps—Backflow valves. City of Arroyo Grande August 2, 2013 Page 13 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report The SSMP should be updated to incorporate the following Arroyo Grande Municipal Code Sections: ■ 13.12.110 – Groups of houses or buildings on one lot—Connections to main sewers. ■ 13.12.140 –Approval—Required. ■ 13.12.150 –Approval—Process. The SSMP should also be updated to include a link to the location of the City Public Works Department's Standard Plans on the City's website. The section above is in substantial compliance with the above requirement. See recommendations at the end of the Legal Authority section of this report. Section D.13(iii)(c): The City does not own and, therefore, does not require access to maintain or repair any portion of a lateral. The City ensures access for inspection for portions of the lateral owned or maintained by a resident or business in the following Arroyo Grande Municipal Code Sections: ■ 13.12.270 – Inspection required. ■ 13.12.500 – Right of entry. The section above is in compliance with the above requirement. See recommendations at the end of the Legal Authority section of this report. Section D.13(iii)(d): The City has the authority to limit the discharge of FOG and other debris that may cause blockages in the sanitary sewer system through SSLOCSD's FOG Ordinance, Ordinance No. 2008-01, and in Arroyo Grande Municipal Code Section 13.12.400 – Prohibited discharges. The SSMP should be updated to incorporate the adopted SSLOCSD FOG Ordinance, Ordinance No. 2008-01, and remove the reference to Arroyo Grande Municipal Code Section 13.12.270 – Inspection required., since it is not applicable to this SSMP requirement. The section above is in substantial compliance with the above requirement. See recommendations at the end of the Legal Authority section of this report. Section D.13(iii)(e): City has the authority to enforce any violation of its sewer ordinances in the following Arroyo Grande Municipal Code Chapters and Sections: • Chapter 1.16– Penalty Provisions • Chapter 9.12 – Nuisances • Section 13.12.470 – Delinquencies—Collection. • Section 13.12.480 – Delinquencies—Liens. • Section 13.12.490 – Enforcement—Delegation of duty. City of Arroyo Grande August 2, 2013 Page 14 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report The SSMP should be updated to incorporate Arroyo Grande Municipal Code Chapters 1.6— Penalty Provisions and 9.12— Nuisances and to reference that SSLOCSD Resolution No. 2011- 295 is utilized to enforce any violations of the SSLOCSD FOG Ordinance. The reference in the SSMP for Arroyo Grande Municipal Code Sections 13.04.070 — 13.04.080 should be removed since they pertain to the City's water system; not the City's sewer system. The section above is in partial compliance with the above requirement. See recommendations at the end of the Legal Authority section of this report. Sufficiency: Substantial Compliance Reference: 2009 SSMP, p. 16— 18; Arroyo Grande Municipal Code Chapters 1.16 — Penalty Provisions, Chapter 9.12— Nuisances, and 13.12— Sewer Service System; SSLOCSD Ordinances No. 1994-1 and 2008-01. Deficiencies: The SSMP does not include some required Arroyo Grande Municipal Code references for prohibiting illicit discharges, the proper design and construction of sewers and connections, and the authority to enforce any violation of its sewer ordinances. The SSMP also does not include a web link to the City Public Works Department's Standard Plans. The SSMP states that SSLOCSD is in the process of adopting a FOG Ordinance, but the FOG Ordinance was adopted and is in effect. SSLOCSD Resolution No. 2011-295 is not referenced. Recommendation: The SSMP should be updated to incorporate a web link for the City Public Works Department Standard Plans, SSLOCSD's FOG Ordinance, Ordinance No. 2008-01, SSLOCSD Resolution No. 2011-295, and the missing Arroyo Grande Municipal Code references for prohibiting illicit discharges, the proper design and construction of sewers and connections, and the authority to enforce any violation of its sewer ordinances. City of Arroyo Grande August 2, 2013 Page 15 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 4.0 Operation and Maintenance Program [SSSWDR D.13(iv)] SSSWDR D.13(iv) states: The SSMP must include those sections listed below that are appropriate and applicable to the Enrollee's system: (a).Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities; (b).Describe routine preventive and operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) Program should have a system to document scheduled and conducted activities, such as work orders; (c). Develop a rehabilitation and replacement plan to identity and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed to the capital improvement plan; (d).Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and (e).Provide equipment and replacement part inventories, including identification of critical replacement parts. Section D.13(iv)(a): All sewer assets and appurtenances are identified in the map referenced in the City August 2009 SSMP. Two separate map atlases and map books are maintained by the City identifying sewer assets and storm water conveyance facilities that could be impacted by a SSO. Staff currently has a backlog of redline changes for the sewer system for transfer into the sewer system atlas. The City has recently integrated sewer maps into GIS and plans to include stormdrain information as an additional layer for this mapping system. Future updates to the SSMP should include a link or paper copy of the updated sewer and stomdrain atlas. The section above is in compliance with the above requirements. See recommendations at the end of the Operation and Maintenance Program section of this report. City of Arroyo Grande August 2, 2013 Page 16 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Section D.13(iv)(b): The August 2009 City SSMP summarizes goals and Routine Preventative Operation and Maintenance (O&M) activities in this section. O&M relating to sewer line; cleaning, inspection, and minor sewer line repairs are performed by the City staff. Routine O&M for the five (5) City Lift Stations are conducted by City maintenance staff. Lift Stations are inspected and maintained once a week as described in the City of Arroyo Grande Performance Standard Activity Code: 315 - Lift Station Maintenance. Contractors are hired to perform maintenance and repair when significant electrical maintenance or mechanical work is required. The current SSMP references six (6) Lift Stations which should be revised to reflect the five (5) current Lift Stations in operation. Sewer line cleaning activities are organized in the City's 2012 Sewer Main Cleaning Program. Cleaning schedules are divided into twelve (12) distinct sections which are identified in a sewer system map book. Line cleaning records are entered into the City's Sewer Main Cleaning Program Route Sheets. The City's SSMP states that the goal for line cleaning is to clean and flush the entire system annually. While the City has met this goal in the past, there have been two impacts over the past 5 years that have interfered with the continued achievement of this annual goal. First; staff has integrated detailed manhole inspections to be conducted with routine line cleaning activities. This additional work task has impacted the amount of time staff spends cleaning lines. Second; City Sewer Maintenance Staffing levels have been reduced by 2 full time positions over the course of the past five years. Once manhole inspections are complete and historic staffing levels resume, this annual goal may be met. A new cleaning schedule should be identified and integrated into the City's next SSMP update that reflects current staffing levels and workloads. Areas needing more frequent cleaning; High Maintenance Areas (HMAs) or Trouble Spots are discussed in the August 2009 SSMP and scheduled for quarterly cleaning. When problems are found during sewer line cleaning activities, a CCTV inspection is conducted by City staff to determine the conditions of the line. The City also uses chemical root control as a method to address HMAs caused by roots. Records for chemical root control were reviewed as part of this audit. A list of HMAs is not included in the City's SSMP and should be included in the next SSMP update. Manholes receive an inspection during routine sewer line cleaning. Manhole Observation and Inspection Reports are completed for each manhole for future assessment by City staff to create rehabilitation and replacement projects. It should be noted that 500 City manholes were estimated as needing rehabilitation or replacement (R&R) for budgetary projections in the 2012 Wastewater System Master Plan. As previously mentioned, City staff is in the process of inspecting and assessing the condition of all City manholes to help identify and prioritize those manholes that will receive R&R. The section above is in compliance with the above requirements. See recommendations at the end of the Operation and Maintenance Program section of this report City of Arroyo Grande August 2, 2013 Page 17 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Section D.13(iv)(c): The August 2009 SSMP states that the City employs a number of measures to keep the existing sewer system functional ranging from local rehabilitation to complete replacement of the sewer section. It additionally states that the City completes a system survey annually to help establish rehabilitation projects. While the City did complete a 2012 Wastewater System Master Plan, this study and related projects is not included in the current version of the SSMP. The current SSMP does not elaborate on the specific methods and plan used to identify R&R projects. The City should incorporate a specific plan and schedule (2012 Wastewater Master Plan) to identify and address defects in pipelines, manholes, lift stations, and other appurtenances in the next update to the SSMP. The 2012 Wastewater System Master Plan does address the majority of the requirements in this section. This Master Plan provides an assessment of the City's sewer system; Lift Stations, Force Mains, Manholes, and Sewer Line (capacities). CCTV inspections for approximately 60% of the system were also integrated as part of the sewer line assessments referenced in the 2012 Master Plan. This plan includes a prioritized list of projects identified to take place between 2013 and 2037. Projects are grouped by a Priority Ranking of"A", "B", and "C". Project schedules are as follows: • Priority "A" Projects to be conducted between 2013 and 2017 • Priority "B" Projects to be conducted between 2018 and 2027 • Priority "C" Projects to be completed between 2028 and 2037 A short and long term CIP and associated schedule was developed based on the results of the WSMP report through Fiscal Year (FY) 2017/18. The City is currently undergoing a revenue rate study to help fund these projects. This rate study is planned for completion in Spring 2014. A formal plan and schedule to conduct future CCTV inspections and assess sewer line deficiencies was not available at the time of this audit. The SSMP needs to be updated to include reference to specific sections of the 2012 Sewer Master Plan and Rate Study that meet the requirements of this section. A plan and schedule to conduct future CCTV inspections and a system for ranking the condition of sewer pipes and scheduling rehabilitation and replacement needs to be developed and included in the SSMP. The section above is in substantial compliance with the above requirements. See recommendations at the end of the Operation and Maintenance Program section of this report. Section D.13(iv)(d): The August 2009 SSMP states that Staff receives training in system operations and maintenance, safety, and reporting procedures for SSOs. Records for safety training and some routine operations and maintenance activities were reviewed however a formal O&M training program with written procedures was not in place at the time of this audit. Staff is in the process of developing a detailed O&M procedure for Sewer Vac Con use and plans to develop additional procedures in the future; however, there is no formal plan and schedule in place for this task. According to City staff, the City does not employ contractors that would require training in general O&M tasks as they are performed by City staff. Contractors City of Arroyo Grande August 2, 2013 Page 18 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report who are hired by the City are required to be adequately licensed to perform tasks identified in the scope of work identified in each contract. Training procedures for collection system operations, maintenance, and monitoring were not available at the time of this audit. Procedures should be developed for O&M activities that are specific to City sewer O&M. Training should be conducted annually at a minimum or when conditions require more frequent training. The section above is in marginal compliance with the above requirements. See recommendations at the end of the Operation and Maintenance Program section of this report. Section D.13(iv)(e): A list of current collection system critical parts and equipment was provided for maintaining City sewer lines and manholes. The City participates in three (3) separate mutual aid agreements for critical parts and equipment; CAL WARN, San Luis Obispo County Mutual Aid Agreement, and the Multi-County Mutual Aid Agreement. The City also works informally with the City of Grover Beach and South San Luis Obispo County Sanitation District to maintain a list of critical parts and equipment that may be used in the event of a SSO. A list of vendors for items and equipment not kept in stock was not available. A list of critical parts and equipment necessary for the operation and maintenance of City Lift Stations and emergency equipment was not available. The City should develop a comprehensive list of critical parts and equipment for all assets and equipment used in the sewer system and create a vendor list with contact information for parts and equipment that are not easily or reasonably stocked. Include these items in the next update to this SSMP. Formal and informal Mutual Aid agreements should also be incorporated into the next SSMP update. The section above is in partial compliance with the above requirements. See recommendations at the end of the Operation and Maintenance Program section of this report. Sufficiency: Substantial Compliance Reference: 2009 SSMP, p. 19—23; Training Certifications: 2011-2012; CCTV Reports: Volumes 1-III; Sewer Lift Station Logs; 2012 Wastewater System Master Plan; Critical Parts and Equipment List; Dukes Root Control Invoices: 2012; FY 2013/14 Budget; 5-Year CIP Plan (2013/14); Lift Station Maintenance Performance Standard; 2012 Sewer Line Cleaning Program and Procedure; Sewer Main Cleaning Program Route Sheet; SSLOCSD District Manhole Observation and Inspection Report; CAL WARN Agreement; Multi Agency Resource Matrix; Public Works Mutual Aid Agreement; San Luis Obispo County Mutual Aid Agreement. Deficiencies: Lift Station O&M preventative maintenance schedules are not presented in the City SSMP. A schedule for future CCTV, how the pipeline segments are assessed, and the plan for rehabilitation and/or repair of those pipeline segments found to be in need is not discussed in the SSMP. Sections of the 2012 Wastewater System Master Plan (WSMP) and City of Arroyo Grande August 2, 2013 Page 19 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report future Rate Study that can be used to meet the requirements of the Rehabilitation & Replacement Program should be referenced and included in the SSMP. The critical parts and equipment list is not representative of all City owned assets such as Lift Stations and should be improved to identify parts needed to repair critical equipment. Additionally, the City does not have a formal list of vendors and associated contact information for critical parts and equipment not normally kept in stock. An O&M training program and training records demonstrating how staff is trained for O&M activities, such as traffic control, service connection requests, sewer line cleaning, etc., require further development and inclusion in the next update to the SSMP. Recommendation: Deficient sections of the O&M Program to be created and documented in the next SSMP revision include: • Identify and incorporate the Preventative Maintenance plan and schedule for City Lift Stations and include in future updates to the SSMP. • Update Sewer Line Cleaning Schedule to reflect current practices and staffing levels. Include a HMA cleaning list as an attachment to the updated SSMP. • Revise SSMP to reflect current number of Lift Stations in system. • Include a list of FOG and Root related HMAs in the next update to the SSMP. • Develop a formal Rehabilitation and Replacement (R&R) plan that incorporates CCTV sewer line condition assessments. Include the proposed short- and long-term CIP completion schedule generated from the 2012 WSMP and document in a table which projects were initiated and/or completed in FY 2011/12 and years following. • Identify critical parts and equipment necessary for the operation and maintenance of City assets and document them. If parts and equipment are not planned to be stocked by the City, document the vendors for these items and contact information. If equipment is available through mutual aid agreements with neighboring agencies or through contract services, document/reference these agreements in the SSMP. • Develop training procedures specific to City O&M activities and train on these procedures annually. Maintain documentation of this training. • Develop a plan to incorporate and train new staff as current staff nears retirement to insure City "institutional knowledge" is maintained and there is adequate staffing to maintain compliance with requirements found in the SSWDRs. City of Arroyo Grande August 2, 2013 Page 20 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 5.0 Design and Performance Provisions [SSSWDR D.13(v)] SSSWDR D.13(v) states: (a).Design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations, and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; and (b).Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects.

Sufficiency: In Compliance Reference: 2009 SSMP, p. 24; Arroyo Grande Municipal Code Section 13.12; City Public Works Department Standard Plans (20050; The "Greenbook": Standard Specifications for Public Works Construction. Deficiencies: There are no deficiencies. The City is in compliance with this section. Design Standards and Specifications with Testing Procedures and Requirements were reviewed during the Audit. City of Arroyo Grande August 2, 2013 Page 21 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Recommendation: It is recommended that current City Engineering Standards be printed and included in the next SSMP revision. City of Arroyo Grande August 2, 2013 Page 22 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 6.0 Overflow Emergency Response Plan [SSSWDR DA 3(vi)] SSSWDR D.13(vi) states: Each Enrollee shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. At a minimum, the plan must include the following: (a).Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner; (b).A program to ensure appropriate response to all overflows; (c). Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers„ etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP identifies the officials who will receive immediate notification; (d).Procedures to ensure that appropriate staff and contract personnel are aware of and follow the Emergency Response Plan and are appropriately trained; (e).Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and (f). A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated or partially treated wastewater to waters of the United States and minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. Section D.13(vi): The City's SSMP gives a general summary of its Overflow Emergency Response Program (OERP). The physical OERP is found in Appendix "E" of the SSMP. This plan requires additional development to address all of the requirements for an OERP; specifically written procedures to address requirements (a) — (f) in SSMP Element 6 of the SSSWDR and reporting requirements consistent with the SSSWDR. Each OERP Section should mirror the requirements found in Element 6: Sections (a) — (f). Section D.13(vi)(a): Section A of the City OERP includes the City's Notification Procedure. This procedure discusses how the City is notified of a SSO and how staff is dispatched to a SSO through the Police Dispatch Center. A chain of communication showing how first responders and regulatory agencies are notified was reviewed. Contact information for RWQCB staff should be updated in the next formal revision/update of the SSMP. City of Arroyo Grande August 2, 2013 Page 23 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report There were a few discrepancies found in Element 6 of the SSMP: • Reporting Procedures in Section 6.8 (page 29) should include the "2 hour notification requirement" so it is clear to staff that this is a maximum timeframe for notification. Currently this Section states that Category 1 Spills are reported "immediately". • Reporting Procedures in Section 6.12 (page 31) must be changed from a 24 hour phone reporting period to a 2-hour reporting period. Section D.13(vi)(b): A general overview of SSO response was provided; however, a program and associated procedures showing key positions and their responsibility to ensure appropriate response to all overflows was not available at the time of this audit and was not found in the SSMP. Section D.13(vi)(c): A general notification overview and associated organizational flow chart and summary showing key positions and their responsibility to ensure appropriate response to all overflows was reviewed in Element 2: Section 2.6—Chain of Communication for Reporting SSOs. This Section should be revised to state that Cal EMA (State Office of Emergency Services) will be contacted within 2 hours "if the spill is over 1,000 gallons or for any discharge to a drainage channel or a surface water" A formal program with procedures to ensure prompt notification to regulatory agencies and officials were not available for review at the time of this audit. Section D.13(vi)(d): Procedures to ensure appropriate staff and contractor personnel are aware of, follow, and are trained on the Overflow Emergency Response Plan were not available at the time of this audit. No training documentation for SSO response was available during the audit. Section D.13(vi)(e): Procedures to address emergency operations, such as emergency traffic and crowd control and other necessary response activities were not available at the time of this audit. Section D.13(vi)(e): The City OERP does summarize how staff should respond to and contain a SSO. A comprehensive program with specific procedures to contain, prevent, and monitor untreated and partially treated wastewater to waters of the State was not available at the time of this audit. The sections above are in partial compliance with the above requirements. See recommendations at the end of the Operation and Maintenance Program section of this report. Sufficiency: Partial Compliance Reference: 2009 SSMP, p. 25—32, and Appendix E. City of Arroyo Grande August 2, 2013 Page 24 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Deficiencies: Reporting timeframes and notification requirements consistent with the 2008 Monitoring and Reporting Requirements in the SSSWDR must be updated. RWQCB staff contact info requires updating to reflect the current City contact with this agency. Formal, written procedures required above were not provided during the Audit or are included in the SSMP. Evidence of a program to inform and train City Staff and contractors on how to contain and prevent a SSO and conduct follow-up water quality monitoring and an impact assessment was also not provided during the Audit or included in the MRP. Recommendation: This SSMP Section is recommended to be updated with a plan and schedule to create the necessary SSO emergency response programs, procedures, forms, training program, and impact mitigation and assessment program. The SSMP Section must also be updated to include a notification list for SSOs and forms, such as spill volume estimation, water quality monitoring, SSO compliant resolution, etc., that City Staff should be utilizing to document and report SSOs. Reporting timeframes and notification requirements must be updated to be consistent with the Monitoring and Reporting Program in the SSSWDR. RWQCB Staff contact info, which has been informally updated, also requires updating to reflect the current City contact with this agency during the SSMP update. During the next update to the SSMP and OERP, ensure that each section of the OERP mirrors the requirements found in WDR Element 6 Sections (a) — (f). The current OERP contains information, such as that on portable aerators, that is not used by the City for SSO response and mitigation. City of Arroyo Grande August 2, 2013 Page 25 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 7.0 FOG Control Program [SSSWDR DA 3(vii)] SSSWDR D.13(vii) states: Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate: (a).An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG; (b).A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area; (c).The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG; (d).Requirements to install grease removal devices (such as traps or interceptors) and the development of design standards for such devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e).Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; (f). An identification of sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and (g).Development and implementation of source control measures for all sources of FOG discharged to the sewer system for each section identified in (f) above. Section D.13(vii): After the issuance of the SSSWDR, the City determined that FOG is an ongoing problem in the sewer collection system, and a FOG Program was needed. The City has over fifty-three (53) food service establishments (FSEs) in its service area. The City is one (1) of the three (3) Member Agencies (MAs) tributary to SSLOCSD and part of a MA Agreement with SSLOCSD. The MAs contracts their FOG Control Program management and implementation to SSLOCSD through the MA Agreement, and Wallace Group provides these services as SSLOCSD's contract District Engineer. In this Audit, the FOG Control Program presented in the 2009 SSMP was evaluated against the SSSWDR Section D.13(vii) requirements included above. The effectiveness of the FOG Control Program is evaluated at the end of this section. City of Arroyo Grande August 2, 2013 Page 26 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Section D.13(vii)(a): The City's SSMP describes public outreach for FOG from its inception in 2007. Public education is conducted with FSEs during semiannual inspections each fiscal year. An assortment of literature is distributed to each FSE, including: best management practices, certified grease hauler list, cleaning record forms, and no grease posters for display in FSE kitchens. Inspectors discuss program parameters and strategies to keep FOG from entering the sewer system during each inspection. Public education and outreach is documented for FSE's within the City limits. Residential outreach regarding FOG is discussed in the SSMP as being conducted through flyers at public meetings, information in billing statements, and door hangers for residential areas prone to FOG. The City conducted an outreach study in 2009 and 2010, which included lift station #4 and the ninety-seven (97) homes, which discharge to lift station #4, since it was an area with a known grease problem. In May 2009, the City cleaned the wet well and measured the concentration of grease build-up. In August 2009, the City vacuumed and cleaned the wet well again and distributed informational flyers regarding grease disposal and grease build-up to the ninety-seven (97) homes in the study area. The City re-inspected lift station #4 and measured the concentration of grease build-up on November 2, 2009. Since there was no improvement in the amount of grease build-up, the City cleaned lift station #4 and redistributed the same flyers to the same ninety-seven (97) residences. Lift station #4 was inspected again and the concentration of grease build-up in the wet well was measured on February 5, 2010. Again, there was no improvement in the amount of grease discharged. The City also published an article regarding FOG in the City's April — June 2013 newsletter, Stagecoach Express: Volume 21, Number 2. The section above is in compliance with the above requirement. Section D.13(vii)(b): The 2009 SSMP states that information concerning how to dispose of FOG generated within the City's service area is disseminated under the public FOG education program, which is described above in response to SSSWDR Section D.13(vii)(a). The SSMP also includes a list of companies FSEs may utilize for the collection and disposal of FOG in SSMP Appendix F. The section above is in compliance with the above requirement. Section D.13(vii)(c) — (e): The legal authority to prohibit discharges to the collection system and identify measures to prevent FOG-caused SSOs is provided in the Arroyo Grande Municipal Code and SSLOCSD FOG Ordinance, Ordinance No. 2008-01. The 2009 SSMP gives a brief description of the SSLOCSD FOG Ordinance, which was in the process of being adopted at the time of the SSMP's approval and adoption, and references SSLOCSD's Pretreatment Ordinance, Ordinance No. 1994-1 as the ordinance being used to achieve the required legal authorities. The SSMP needs to be updated to include the adopted SSLOCSD FOG Ordinance and to reference the appropriate Arroyo Grande Municipal Code sections, which provide the legal authorities required by the SSSWDR.

City of Arroyo Grande August 2, 2013 Page 30 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 8.0 System Evaluation and Capacity Assurance Plan [SSSWDR D.13(viii)] SSSWDR D.13(viii) states: The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer system sections for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include: (a).Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to a SSO discharge deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events; (b).Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and (c). Capacity Enhancement Measures: The steps needed to establish a short- and long-term Cl P to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. (d).Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D.14. Section D.13(viii)(a): The City SSMP refers to the 2001 Wastewater System Master Plan (WSMP) that evaluated physical and hydraulic conditions of the City sewer system. In 2012, the City developed a new WSMP which outdates the 2001 study. The 2012 Wastewater System Master Plan does address the requirements in this section. The 2012 WSMP should be incorporated into future updates and revisions to the SSMP to address the requirements found in this section. The 2012 WSMP provides hydraulic evaluations of City: lift stations, force mains, and gravity sewer lines. Hydraulic evaluations were conducted to model existing dry and wet weather conditions and future dry and wet weather conditions expected at"build out", which represent "worst case scenario" flow conditions. The City has not experienced a history of SSOs related to deficient system capacities. The section above is in compliance with the above requirements. City of Arroyo Grande August 2, 2013 Page 1 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Section D.13(viii)(b): Design criteria were identified in the 2012 WSMP and used in system modeling to assess the hydraulic conditions existing in the system. These criteria were used to make recommendations for hydraulic upgrades in City lift stations, force mains, and gravity sewer lines. The section above is in compliance with the above requirements. Section D.13(viii)(c) — (d): This plan includes a prioritized list of projects identified to take place between 2013 and 2037. Projects are grouped by a Priority Ranking of"A", "B", and "C". Project schedules are as follows: • Priority "A" Projects to be conducted between 2013 and 2017 • Priority "B" Projects to be conducted between 2018 and 2027 • Priority "C" Projects to be completed between 2028 and 2037 A short and long term CIP and associated schedule was developed based on the results of the WSMP report through Fiscal Year (FY) 2017/18. The City is currently undergoing a revenue rate study to help fund these projects. This rate study is planned for completion in Spring 2014. The 2012 WSMP and a project summary and schedule for capital projects in each Fiscal Year through 2017/18 need to be included in the next update of the SSMP. The findings of the revenue rate plan and subsequent rate structure to support capital improvements should also be included in this update. The sections above are in substantial compliance with the above requirements. Sufficiency: In Substantial Compliance Reference: 2009 SSMP, p. 40; 2012 WSMP; 5-Year Capital Improvement Program Budget: 2013-2014. Deficiencies: The City has not presented in the SSMP a plan and schedule for the completion of capital improvement projects identified in the 2012 WSMP. Recommendation: Incorporate the WSMP and associated CIP plan and schedule into annual revisions to the SSMP. Present the plan to fund the capital improvement projects identified in the pending revenue rate study. City of Arroyo Grande August 2, 2013 Page 2 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 9.0 Monitoring, Measurement, and Program Modifications [SSSWDR D.13(ix)] SSSWDR D.13(ix) states: The Enrollee shall: (a).Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities; (b).Monitoring the implementation and, where appropriate, measure the effectiveness of each section of the SSMP; (c).Assess the success of the preventative maintenance program; (d).Update program elements, as appropriate, based on monitoring or performance evaluations; and (e).Identify and illustrate SSO trends, including: frequency, location and volume. Section D.13(ix)(a): The City utilizes Work Orders to keep records of preventative maintenance and rehabilitation and replacement activities and maintains a folder of SSO records, which can be used to establish and prioritize appropriate SSMP activities. The section above is in compliance with the above requirement. See recommendations at the end of the Monitoring, Measurement, and Program Modifications section of this report. Section D.13(ix)(b) and(c): The SSMP states that the SSMP will be reviewed annually to ensure all the provisions are implemented and that the effectiveness will be discussed at quarterly Public Works Department Staff meetings, but there is no record of formal evaluations of the implementation or effectiveness of each SSMP Element or preventative maintenance activities. Items of Interest memorandums are submitted to the City Council every two to three weeks, which provide updates on significant work completed on the sanitary sewer system, such as line cleaning, lift station cleaning, manhole inspections, and CIPs. These memorandums are utilized to monitor the implementation of the City's preventative maintenance and rehabilitation and replacement activities. The section above is partial compliance with the above requirement. See recommendations at the end of the Monitoring, Measurement, and Program Modifications section of this report. City of Arroyo Grande August 2, 2013 Page 1 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report Section D.13(ix)(d): The City's SSMP contains informal revisions, but the revisions were not based on a formal SSMP Element monitoring or performance evaluation. A revision tracking table should be added to the SSMP to document any SSMP revisions and updates. The section above is in marginal compliance with the above requirement. See recommendations at the end of the Monitoring, Measurement, and Program Modifications section of this report. Section D.13(ix)(e): The City has identified FOG and roots to be the primary causes of SSOs in its sanitary sewer system. SSMP Appendix H contains a table, which tracks the frequency, location, cause, and volume of SSOs. This table was updated during the 2011 SSMP Audit, which is included in SSMP Appendix I, but this information should be transferred to the table included in SSMP Appendix H and discussed in SSMP Element 9: Monitoring, Measurement, and Program Modifications. The SSO, which occurred on 09/26/2011, needs to be added to the SSO tracking table. The section above is substantial of compliance with the above requirement. See recommendations at the end of the Monitoring, Measurement, and Program Modifications section of this report. Sufficiency: Substantial Compliance Reference: 2009 SSMP, p. 41 —42 and Appendices H and I; Example SSO Reports. Deficiencies: The City does not have a written plan to formally evaluate the implementation or effectiveness of each SSMP Element and update the SSMP based on these evaluations. The City's SSMP contains informal revisions, but the revisions were not based on a formal SSMP Element monitoring or performance evaluation. A revision tracking table should be added to the SSMP to document any SSMP revisions and updates. The SSO data and trending information should be transferred from the 2011 SSMP Audit Report included in SSMP Appendix I to the table included in SSMP Appendix H and discussed in SSMP Element 9: Monitoring, Measurement, and Program Modifications. The SSO, which occurred on 09/26/2011, is not included in the SSO tracking table. Recommendation: Create a written program to schedule, track, and evaluate the effectiveness of preventative maintenance for the sanitary sewer system. Create a plan and schedule to review and asses the effectiveness of each SSMP Element. Complete these plans and records and incorporate them into the update of this SSMP Element. The SSO data and trending information should be transferred from the 2011 SSMP Audit Report included in SSMP Appendix I to the table included in SSMP Appendix H and discussed in SSMP Element 9: Monitoring, Measurement, and Program Modifications. The SSO, which occurred on 09/26/2011, needs to be added to the SSO tracking table. City of Arroyo Grande August 2, 2013 Page 2 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 10.0 SSMP Program Audits [SSSWDR D.13(x)] SSSWDR D.13(x) states: As part of the SSMP, the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the Enrollee's compliance with the SSMP requirements identified in this subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them. Section D.13(x): SSMP audits are required to be performed a minimum of every two years from the date of required adoption, August 2, 2009. The first SSMP Audit was performed before August 2, 2011, and this SSMP Audit is being completed prior to the August 2, 2013 deadline. All SSMP Audit Reports are kept on file with the SSMP. The SSMP Audit Report, which is included in SSMP Appendix I, was not used, because it does not adequately evaluate the effectiveness of the SSMP and its implementation. It is recommended that the SSMP Audit Report included in SSMP Appendix I be removed, and the SSMP be updated to describe the audit process, which was utilized to perform this SSMP Audit. Sufficiency: In Compliance Reference: 2009 SSMP, p. 43 and Appendix I Deficiencies: There are no deficiencies. Recommendation: Remove the SSMP Audit Report Form included in SSMP Appendix 1, and update the SSMP to describe the audit process, which was utilized to perform this SSMP Audit. City of Arroyo Grande August 2, 2013 Page 1 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report 11.0 Communication Program [SSSWDR DA3(xi)] SSSWDR D.13(xi) states: The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented. The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee's sanitary sewer system. Section D.13(xi): The SSMP states that the SSMP is available for public review and comment on the City of Arroyo Grande's website, www.arroyogrande.org, on the Recreation and Maintenance Services Department webpage, but the auditors were not able to locate the electronic copy of the SSMP. The SSMP should be posted on the City's website and the SSMP should be updated with the appropriate link. The public is also updated on City projects and events through the City's newsletter, Stagecoach Express. An article regarding trash disposal in toilets was published in Volume 20, Number 2 of the Stagecoach Express for April — June 2012, and an article regarding FOG disposal was published in Volume 21, Number 2 of the Stagecoach Express for April — June 2013. The SSMP should be updated to include a discussion and example of outreach conducted using the Stagecoach Express or a link for where the Stagecoach Express articles can be read online. Items of Interest memorandums are submitted to the City Council every two to three weeks, which provide updates on significant work completed on the sanitary sewer system, such as line cleaning, lift station cleaning, manhole inspections, and CIPs. These memorandums are utilized to monitor the implementation of the City's preventative maintenance and rehabilitation and replacement activities and to update the City Council on the performance and implementation of these SSMP activities. A formal program for relaying the information form the Items of Interest memorandums to the public through the City's regular, televised City Council Meetings should be established, and the SSMP should be updated to include a discussion and example of the Items of Interest memorandums. The SSMP states that Waste Discharge Requirements (WDR) Annual Reports are completed in January of each year, submitted to the RWQCB, and refer to the SSMP and any changes that have been made over the last year. These Annual Reports historically included information regarding a management plan required by the City's WDR, but the WDR was rescinded and that management plan was replaced by the SSMP. This reference needs to be removed since the City no longer completes these annual reports, and it is not applicable to communication regarding the SSMP. The SSMP states that City Staff is trained in the use and implementation of the SSMP relative to any major changes that occur and are kept informed of minor changes via City email or memos. No evidence of this is included in the SSMP or was reviewed during the SSMP Audit. The SSMP needs to be updated to include evidence of these activities or reference where these records are maintained. City of Arroyo Grande August 2, 2013 Page 1 of 39 Sewer System Management Plan—Revision 0 SSMP Audit Report The City of Arroyo Grande, City of Grover Beach, and Oceano Community Services District manage and operate sanitary sewer systems, which are tributary to SSLOCSD's sanitary sewer system. Examples of Meeting Agendas and Minutes for monthly Collection System Coordination Meetings, which were attended by all four agencies, were reviewed during this SSMP Audit, but there are no records of any Collection System Coordination Meeting since the March 2013 meeting. However, the next meeting is scheduled for August 2013. The SSMP needs to be updated to discuss the Collection System Coordination Meetings. The City also has four neighborhoods with small, private collection systems, which are within the City limits and discharge into the City's collection system. The residents of these neighborhoods receive outreach from the City, such as the Stagecoach Express, and the City is prepared to coordinate with these neighborhoods if problems arise, such as inflow and infiltration or FOG build-up. Sufficiency: Partial Compliance Reference: 2009 SSMP, p. 44; Stagecoach Express: Volume 20, Number 2; Stagecoach Express: Volume 21, Number 2; Collection System Coordination Meeting Agendas and Minutes. Deficiencies: The SSMP was not available on the City's website as stated in the SSMP. A formal program for communicating further development, implementation, and performance of the SSMP with the public does not exist. Collection System Coordination Meetings for SSLOCSD and the Member Agencies were conducted through March 2013, but, as of this date, further meetings have not been conducted per the monthly meeting schedule. The SSMP does not include a record or a discussion with examples of the City's outreach activities. The SSMP references WDR Annual Reports, which are not applicable to the SSMP and are no longer completed by the City. The SSMP also needs to be updated to include evidence of Staff training on changes to the SSMP. Recommendation: The SSMP should be posted on the City's website and the SSMP should be updated with the appropriate link. The City should establish a formal SSMP Communication Program for communicating further development, implementation, and performance of the SSMP with the public and document this program in the SSMP. The SSMP should be updated to include a record of all outreach and coordination with examples or links to where the information can be accessed online, and the reference to the WDR Annual Reports should be removed. The SSMP also needs to be updated to include evidence of Staff training on changes to the SSMP.
