StORTI water runoff transports pollutants from residences, streets, parking lots, and other sources to creeks, rivers, and estuaries. Activities such as land clearing, excavation and filling, use of fertilizers, pesticides and herbicides, illegal dumping, and even improper disposal of pet waste can generate storm water pollution. Water quality concems that result from storm water pollution include suspended sediment, pathogens, nitrates, chlorides, sodium, polychlorinated biphenyls (PCBs), and low dissolved oxygen levels. Storm water pollutants can inhibit the "beneficial uses" of a waterway that range from human contact and recreational uses to uses for commercial fisheries, drinking water, and habitat for animals and plants. Until recently, storm water runoff in areas with a population of less than 100,000 people was not regulated. Although many existing storm water runoff controls have been in place, there has not been an integrated and comprehensive approach to preventing pollution from storm water runoff in these areas. Regulatory Requirements In 1972, the Federal Water Pollution Control Act, which established the NPDES program was adopted. The NPDES program regulates the discharge of waste waters from point sources to surface waters. The Federal Water Pollution Control Act was amended in 1977 and became known as the Clean Water Act (CWA). In 1987 the CWA was again amended to add section 402, which established a framework for regulating discharges from municipal separate storm water systems (MS4s) as a special category of point source under the NPDES Program. Enacted in 1990, Phase I of the Storm Water Rule applied to municipal separate storm sewer systems (MS4s) with a service population greater than 100,000, to construction projects affecting five acres or more, and to certain industrial activities. Phase II of the Storm Water Rule is generally applicable to MS4s serving an urban population greater than 10,000 and construction activities affecting 1 acre or more. Under the Storm Water Phase II Rule small MS4s that meet specific criteria must obtain a National Pollutant Discharge Elimination System (NPDES) permit for storm water discharges. NPDES storm water permits will be issued by the State Water Resources Control Board (SWRCB) and must be renewed every five years. The first five-year permit term will begin on October 27, 2003, at which time the small MS4's are required to file a Notice of Intent (NOI) to comply with the State's General Permit. To comply with the State's General Permit, the small MS4 operator must implement a Storm Water Management Plan (SWMP) that reduces the discharge of pollutants to the "maximum extent practicable", that protects water quality, and that satisfies the requirements of the Clean Water Act. The City must submit an NOI, a permit fee, and their SWMP on or before the State's General Permit deadline. 1 --"_., Scope of the Storm Water Management Plan In order to meet the requirements of the Storm Water Phase II Rule, the Cities of Grover Beach, Arroyo Grande, and Pismo Beach have formed an informal partnership to address local storm water quality issues. The Cities also coordinate with the San Luis Obispo County Partnership for Water Quality, which includes numerous cities, and the County of San Luis Obispo. This Storm Water Management Plan (SWMP) was created to serve as a guide for developing and implementing the NPDES Phase " requirements for storm water discharges. This document describes how pollutants in stonn water will be controlled and also describes recommended Best Management Practices (BMPs) that address the six required minimum control meas~res in a small MS4. Each BMP is accompanied by measurable goals to be achieved during the permit term, as a means of determining program compliance and accomplishments, and as an indicator of program effectiveness. A "Small Municipal Separate Storm Sewer System or Small MS4" is a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man made channels, or storm drains) that are: 1. Owned or operated by the United States, a State, city, town, borough, country, parish, district, association, or other public body (created by or pursuant to State law) having jurisdiction over disposal of sewage, industrial wastes, storm water, or other wastes, including special districts under State law as a sewer district, flood control district,drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or designated and approved management agency under section 208 of the CW A that discharges to waters of the United States. 2. Not defined as "large" or "medium" municipal separate storm sewer system. 3. Small. MS4s including systems similar to separate storm sewer systems in municipalities, such as systems at military bases, large hospital or prison complexes, and highways and other thoroughfares, but do not include separate storm sewers in very discrete areas, such as individual buildings. This program includes specific BMPs for the six minimum control measures and defines measurable goals for each control measure. Best Management Practices for storm water management are defined as schedules of activities, prohibition of practices. maintenance procedures, the use of pollution control devices and other management practices used to prevent or reduce the amount of pollution introduced to receiving bodies from storm water runoff. Recommended BMPs for each of the six minimum control measures are provided in Section 2 through 7 of this plan. The "Maximum Extent Practicable" (MEP) standard requires the development and implementation of BMPs and the achievement of measurable goals to satisfy the six minimum control measures. Determining whether a BMP protects water quality to the maximum extent practicable is subjective. MEP is generally a result of emphasizing pOllution prevention. Source control BMPs are the first line of defense and may be used in combination with treatment methods where appropriate as additional lines of defense. The MEP approach is an evolving, flexible and advancing concept, which considers technical and economic feasibility. As knowledge about controlling urban runoff continues 2 to evolve, so does that which constitutes MEP. The individual and collective activities described in this Storm Water Management Plan (SWMP) are the recommendations for reducing or eliminating pollutants in storm water to the MEP. The "Measurable Goals" should reflect the specific needs and characteristics of the city according to the EPA guidelines. According to the program guidelines, the measurable goals do not necessarily have to be quantitative, but should be attainable and controllable. Measurable goals shall include at a minimum, a description of the action that will be taken to implement each BMP, what is anticipated to be achieved by each goal, and the frequency and dates for which such actions will be taken. Inspections and monitoring are both important to a storm water program. Visual inspections and monitoring of storm water runoff and infrastructure (e.g. drop inlets, basins, and gutters), can determine the effectiveness of a storm water program. Through visual inspections and monitoring, non-storm water discharges can be discovered. and subsequently eliminated , maintenance needs can be identified, and visual pollutants and erosion problems can be detected. Inspection of facilities is also important to ensure proper BMP implementation and maintenance at businesses and municipal sites, and to detect non-storm water discharges. Monitoring can also be conducted to involve the public through citizen monitoring groups, to identify and target pollutants of concem, and to illustrate water quality improvements and permit compliance. Area of Permit Coverage One of the first steps in developing the SWMP was to determine the storm water areas to be managed. All urbanized areas within the boundaries of the City are included as part of this SWMP. Agricultural lands within the boundaries of the City is not addressed under the general permit for Small MS4's. Storm Water Phase II Program Goals and Objectives As declared by the EPA, the goal of the Storm Water Management Program is: (1) to protect the water quality of the Nation's waterways by reducing the quantity of pollutants that storm water picks up and carries into storm sewer systems and natural drainage ways (e.g. creeks, lakes, estuaries, and the ocean) during storm events to the "maximum extent practicable," and (2) to satisfy the requirements of the Clean Water Act. To meet these goals the Phase \I Program requires a "Small MS4" to develop, implement, and enforce a Storm Water Management Plan (SWMP) that includes six minimum control measures: 1. Public Education and Outreach 2. Public Participation and Involvement 3. Illicit Discharge Detection and Elimination 4. Construction Site Runoff Control 5. Post-Construction Runoff Control 6. Pollution Prevention and Good Housekeeping for Municipal Operations 3 -~._--- _ _..._____.'.m_'_ Funding Funding for this program is part of the overall Storm Water Management Plan and has been identified in each of the target date for activities section of the plan. Potential sources for funding that will be investigated include: State and Federal grants, establishing a separate storm water utility, and other potential funding sources that are being developed statewide SECTION 2: PUBLIC EDUCATION AND OUTREACH This control measure is intended to ensure greater public support and compliance for the storm water management plan. Specifically, these efforts are directed to teach the public the importance of protecting storm water quality, both for the benefit of the environment and human health. The role of each community member, both at home and work, is a major emphasis of this minimum control measure. Objectives and Requirements ~ Understand the public perceptions and attitudes towards the problem of urban runoff; and ~ Raise. public awareness about urban runoff pollution and its impacts on the community's water resources; and ~ Educate the community about specific pollutant sources and what individuals can do to reduce urban runoff pollution; and ~ Foster participation through community-based projects or volunteer activities focused on pollution prevention. To meet these objectives, the requirements of the Public Education and Outreach component of the _ Storm Water Program are to: ~ Implement a public education program which distributes education materials and conducts outreach activities aimed at informing the public about the impacts of storm water discharges on local water bodies, and receiving waters; and ~ Implement appropriate BMPs and develop achievable and measurable goals in order to assess the success of the public education and outreach program. Minimum Control Measures for Public Education and Outreach Program BMP 2.1: Provide a wide variety of educational information on non-point source pollution and urban storm water management including informational brochures, posters, and fact sheets. Justification: There are many different opportunities to educate the public regarding the impacts of storm water discharges to local waterways.

City crews also perform clean-up of dog mess at City parks. 6 SECTION 3: PUBLIC PARTICIPATION AND INVOLVEMENT This control measure is intended to foster active community support for the storm water management program and recommendations for its implementation. Participation by the public ensures that the program reflects community values and priorities and thus has the highest potential for success. Objectives and Requirements ~ Raise public awareness about urban runoff pollution; and ~ Involve the public in developing and implementing the Storm Water Management Plan in order to promote pUblic interest and support. To meet these objectives, the requirements of the Public Participation and Involvement component of the Storm Water Program are to: ~ Comply with all State, and local public notice requirements; and ~ Involve the public in the continuing development and refinement of the Storm Water Management Plan; and ~ Allow the public to review the permit and the Storm Water Management Plan; and ~ Include a procedure to receive and respond to comments from the public regarding the Storm Water Management Plan; and ~ Implement appropriate BMPs and develop achievable and measurable goals in order to assess the success of the public participation and involvement program. Minimum Control Measures for Public Participation and Involvement Program BMP 3.1: Develop a mechanism to solicit public participation / input on the City's Storm Water Plan. Justification: Involving the public early in development of the Storm Water Management Plan should increase support for the program and provide additional input and suggestions to help shape the program. Measurable Goals: Document the number of citizen surveys distributed through the City utility bill and responses received. BMP 3.2: Provide opportunities for public participation and involvement in the Storm Water Management Plan and conduct activities to protect urban water quality. Justification: By involving members of the community, the storm water program can be sustained and implemented by others than just the City's efforts. To draw upon the input and experience of as many interested people as possible to help achieve the goal of improved water quality. Measurable Goals: Document the number of storm drain inlets stenciled; Document the number of public outreaches. 7 BMP 3.3: Establish a Community Committee Justification: By involving members ofthe community, the Storm Water Management Plan can be sustained and implemented by others than just the City's efforts. By providing opportunities for community members to discuss areas of concem, information can be relayed to the appropriate City Staff members. Measurable Goal: A committee will be established for the permit area within one year of the programs conception. Target Date for Activities: Year 1 Volunteer organizations begin storm sewer inlet stenciling; Establish a steering 2003-2004 committee, Citizen survey developed and distributed in Utility Bill.

Existing Ordinances I Policies I Programs I BMPs: ~ Conduct creek clean-up days and participate in Adopt-A-Creek program. ~ Storm drain inlet stenciling. 8 SECTION 4: ILLICIT DISCHARGE DETECTION AND ELIMINATION This control measure of the Storm Water Management Plan is intended to reduce pollutants in storm water runoff to receiving waters. It requires the development and implementation of a system to identify and eliminate sources of illicit discharges and illegal dumping. The program depends on a number of partners including the public and other local agencies. An illicit discharge is defined as any discharge to the municipal storm drain system that is not composed entirely of storm water, except for discharges authorized by an NPDES permit. Illicit discharges may enter the storm sewer system through either (1) direct connections (accidental or deliberate connections to storm sewers), or (2) indirect connections (i.e. filtering into storm sewers from cracked wastewater pipes, spills draining into storm sewer inlets, or waste waters or materials deliberately dumped into storm sewers). Discharge sources must be controlled and illegal behavior prevented. Objectives and Requirements ~ Control illicit discharges by'conducting field surveys / investigations of the storm sewer system to identify and eliminate improper connections and discharges; and ~ Prevent improper disposal of waste through public education and providing appropriate waste material disposal options and incentives; and ~ Contain and clean-up accidental spills using proper clean-up and disposal materials and methods. To meet these objectives, the requirements of the Illicit Discharge Detection and Elimination component of the Stonn Water Program are to: ~ Develop a storm drain map that shows the location of all outfalls and the names and locations of all waters that receive discharges from the outfalls; and ~ Develop enforceable means to prohibit non-storm water discharges (i.e. an ordinance or other regulatory mechanism); and ~ Develop a City-wide plan to detect and address non-storm water discharges; and ~ Educate the general public, businesses, and public employees about the hazards (and legal consequences) of illicit discharges. The following table of discharges may be exempted from regulations unless they are determined to be a significant source of pollution or a nuisance. 9 ----._- Table 4.1: water line flushing II irrigation water landscape irrigation II springs diverted stream flows II water from crawl space pumps rising ground waters II footing drains potable water discharges II lawn watering foundation drains II street wash water uncontaminated pumped ground water II air conditioning condensation flows from riparian habitats and wetlands II individual residential car washing dechlorinated swimming pool discharges I emergency fire fighting discharges Discharges or flows from fire fighting activities are excluded from the effective prohibition against non-storm water and need only be addressed where they are identified as significant sources of pollutants. Minimum Control Measures for Illicit Discharge Detection and Elimination Program BMP 4.1: Prepare a Storm Drain System Map Justification: A storm drain system map will help the City to identify outfalls with dry weather flows and other suspicious discharges that need monitoring or investigation. It is also essential for maintenance and long-term planning of the storm drain system. Measurable Goal: Completion of the Storm Drain Systems Map. BMP 4.2: Conduct field sUNeys / pipe inspections to identify illicit dischatges. Justification: Poor infrastructure conditions in older sections of the City or outdated building codes may have resulted in the direct connection of waste water pipes, which should be removed or rerouted. Other connections may have been established illegally that are leaking targeted pollutants into the storm drain system. Measurable Goal: Document the number of illicit connections identified; illicit discharge connection locations prioritized for removal; Document the number of illicit connections eliminated. 10 -~ BMP 4.3: Review existing ordinance or develop an ordinance prohibiting illicit discharges, with appropriate enforcement provisions. Justification: The requirements for non-storm water discharges are changing. Review existing ordinance or develop an ordinance that provides a broader description of what is an allowable discharge and what is an illicit discharge and sites appropriate sanctions for violators is required. It is another tool that the City needs to have in order to reduce pollutant levels in local waterways. Measurable Goal: Ordinance established; Number of violations enforced; Number of informational flyers developed and distributed; Number of City employees trained; Number of citizen complaints received. Target Date for Activities: Year 1 Storm Drain System Map 25% completed; Initial investigation of Illicit 2003-2004 Discharge locations, Training for City employees. Year 2 Storm Drain System Map 50% completed; Training for City employees 2004-2005 completed; Informational flyers developed and distributed; 25% of Storm Sewer System inspected for sources of illicit discharges. Year 3 Storm Sewer System Map 75% completed; Enforcement provisions in place; 2006-2007 50% of storm sewer system inspected for sources of illicit discharges; Ordinance developed and in place. Year 4 Storm Sewer System Map 100% completed; 75% of storm drain system 2007-2008 inspected for sources of illicit discharges. Year 5 100% of storm drain system inspected for sources of illicit discharges; Citations 2008-2009 issued for abatement of illicit connections; Citizen complaints received; Investigation locations prioritized; Develop funding sources. 6 Inspection of Storm Drain System; Inspections for illicit discharge connections. Existing Ordinances I Policies I Programs I BMPs: ~ City participates with Integrated Waste Management Board (SLO) and the Emergency Service Department for Hazardous Materials I Spill Response. 11 .----~ ----------~_.. ~~_.__. SECTION 5: CONSTRUCTION SITE RUNOFF CONTROLS This control measure of the Storm Water Management Plan is intended to prevent soil and. construction waste from entering storm water. Sediment is usually the main pollutant of concem; during a short period of time, construction sites can contribute more sediment to creeks than can be deposited naturally over several decades. The resulting siltation, and contribution of other pollutants from construction sites can cause physical, biological, and chemical harm to local waterways. Objectives and Requirements .. Develop, implement, and enforce a program to reduce the amount of pollutants in storm water runoff from construction activities that result in land disturbance of one acre or more. To meet this objective, the requirements of the Construction Site Runoff Control component of the Storm Water Program are to: '.. Develop an ordinance or other regulatory mechanism, requiring the implementation of proper erosion and sediment controls on construction sites, and penalties for non- compliance; and .. Require construction site operators to implement appropriate and effective erosion and sediment control BMPs to reduce or eliminate storm water pollution; and .. Require construction site operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste at the construction site the may cause adverse impacts to water quality; and .. Develop procedures for site plan review of construction plans to address water quality impacts; and .. Develop procedures for site inspections and enforcement of control measures; and .. Establish procedures for receiving information I concerns about construction site practices from the public. Minimum Control Measures for Construction Site Runoff Program BMP 5.1: Develop an ordinance specifically addressing construction site erosion and sediment control with appropriate penalties for non-compliance and BMPs to implement. Justification: An ordinance provides more specific guidelines regarding implementation and enforcement of erosion control measures. Measurable Goals: Revised grading ordinance established; Number of enforcement actions taken; Number of Contractors and Developers informed; Number of informational materials created and distributed; Number of approved BMPs in place; BMP 5.2: Develop procedures to ensure adequate review of site plans to address erosion and sediment control on al/ construction sites. 12 - - _...~ Justification: Planning for erosion and sediment control on small construction sites is an important activity, best done before construction actually starts. The change from previously requiring approval of Erosion and Sediment Control plans (ESC) for sites greater than five acres to requiring them for sites greater than one acre should significantly reduce the erosion and sedimentation 1Tom construction sites. Measurable Goals: Number of Public Works Inspectors trained; Number of reviews completed; Number of site inspections completed. BMP 5.3: Develop procedures for the public to infonn the City about construction site runoff problems and for the City to report back on actions taken. Justification: This information will supplement the City's effort to identify and respond to incidents of soil erosion from construction sites. It will also be another way for the public to become involved in the overall program to reduce pollution in local waterways. Measurable Goals: Procedures for information to be submitted by the public completed; Number of complaints received; Number of violations sited; Number of corrections certified. Target Date for Activities: Year 1 Revise Grading Ordinance 100% completed; City Inspectors trained; 2003-2004 Procedures for site inspection implemented. Year 2 Approved BMPs in place; Contractors informed of training opportunities; 2004-2005 Year 3 Procedures for information submitted by the public in place. Contractors cited 2005-2006 for non-compliance. Year 4 Revised informational materials available. Contractors cited for non- 2006-2007 compliance. YearS Develop funding sources. Contractors cited for non-compliance. 2007-2008 6 Complaints received from public; Site inspections; Contractors informed of training opportunities. Existing Ordinances I Policies I Programs I BMPs: ~ Grading Ordinance. ~ The Public Works Department reviews discretionary projects submitted for impacts to water quality and hydrology. If a project is considered to have a 13 ---~._~~- potentially significant impact to either, the project proponent is required to mitigate impacts to the greatest extent feasible. 14 SECTION 6: POST -CONSTRUCTION RUNOFF CONTROLS This control measure of the Storm Water Management Plan focuses on site and design considerations, which are most effective when addressed in the planning and design stages of project development. Effective long-term management and maintenance are critical, so the best design opportunities are those with minimum maintenance needs. The goal of this control measure is to integrate basic and practical storm water management techniques into new development to protect water quality. Objectives and Requirements ~ Reduce the long term potential for discharge of pollutants into urban runoff from new development and redevelopment. To meet this objective, the requirements of the Post-Construction Runoff Control component of the Storm Water Program are to: ~ Develop regulatory framework requiring the implementation of post-construction runoff controls; and ~ Develop appropriate structural and non-structural BMP strategies to address post- construction runoff; and ~ Ensure adequate long.term operation and maintenance of control measures; and ~ Determine appropriate BMPs and measurable goals to meet these requirements. Minimum Control Measures for Post-Construction Runoff Program BMP 6.1: Develop regulatory framework for addressing post-construction and redevelopment site runoff controls. Justification: Regulations are an effective way to establish performance standards for runoff controls. Urban runoff controls address urban runoff quantity and quality in an effort to eliminate potential pollutant sources from development projects. Owners and developers should be required to provide facilities that minimize the opportunities for pollutants to reach local water bodies. Measurable Goals: Regulations established; Number of enforcement actions; Number of citizen complaints about erosion from new developments. BMP 6.2: Develop non-structural BMPs to ensure adequate post-construction site runoff controls are implemented and maintained. Justification: There are many opportunities to establish effective controls for post..construction site runoff without requiring some additional structures to be built. Proper planning and design of a building site can include features that reduce the amount of runoff after construction is completed. 15 Measurable Goals: Number of projects with approved non-structural BMPs in place; Number of informational materials created and distributed. BMP 6.3: Develop structural BMPs to ensure adequate post-construction site runoff controls are implemented and maintained. Justification: There are many opportunities to establish efff3ctive controls for post-construction site runoff. By requiring innovative storage, infiLtration or vegetative practices to be included in the design of a building site, significant reductions in runoff after construction can be achieved, sometimes reduced to a level less than pre- development flows. Measurable Goals: Number of projects with structural BMPs in place; Number of informational materials created and distributed. Target Date for Activities: Year 1 Informational materials for post-construction runoff control developed and 2003-2004 distributed. Year 2 I City staff members trained. I 2004-2005 Year 3 Non-structural BMPs implemented with new development and redevelopment 2005-2006 proJects; Ordinance developed 50% completed and in place. Year 4 Develop regulations 100% completed and in place. 2006-2007 Year 5 Structural BMPs implemented with new development and redevelopment 2007 -2008 projects; Citations issued for non-compliance; Develop funding sources. 6 Citizen complaints received; Informational material revised. 16 "~--- f SECTION 7: POLLUTION PREVENTION / GOOD HOUSEKEEPING FOR MUNICIPAL OPERATIONS This control measure of the Storm Water Management Plan is intended to assure that the City's delivery of public services occur in a manor protective of storm water quality. Objectives and Requirements .. Reduce the amount and type of pollutants that are discharged from streets, parking lots, material storage areas and vehicle maintenance yards into the storm sewer system. To meet this objective, the requirements of the Pollution Prevention / Good Housekeeping for Municipal Operations component of the Storm Water Program are to: .. Develop and implement an operation and maintenance program for the City to prevent or reduce polluted runoff from municipal operations; and .. Provide employee training on how to incorporate pollution' prevention and good housekeeping into all municipal operations such as park and open space maintenance, fleet and building maintenance, lOads maintenance and storm drain maintenance; and .. Determine the appropriate BMPs and measurable goals to meet these requirements. Minimum Control Measures for Pollution Prevention / Good Housekeeping for Municipal Operations Program BMP 7.1: Develop a Municipal Operations BMP Manual for City facilities covering the following activities (Phase I): a. Veh~~/equ~mentdeanmg b. Vehicle maintenance c. Veh~~/equ~mentpammg d. Outdoor materials storage e. Waste handling/storage f. Maintenance of paved/unpaved surfaces g. Storm water runoff/drainage Justification: The City should be a leader in implementing BMPs to ensure that the Corporate Yard and other City facilities comply with NPDES Phase II regulations which require the owner or operator to develop and implement a cost-effective operation and maintenance program with the ultimate goal of preventing and reducing pollutant runoff from municipal operations. Measurable Goal: Municipal Operations Plan for Corporate Yard developed. BMP 7.2: Develop a Municipal Operations Program with the following categories (Phase II): 17 - . ---------...-- ----- a. Street sweeping and cleaning. b. Sidewalk, plazas, parking lots. c. Municipal landscaped areas (parks, medians, landscaping) d. Storm drain inlet/pipe cleaning e.

".,.~,,,--,,,,,,- SECTION 8: MONITORING AND REPORTING Monitoring and Reporting Requirements The purpose of monitoring and reporting is to document successful implementation of the SWMP. The draft general permit requires annual reports to be submitted starting in August 2004. The City intends these annual reports to cover the fiscal year immediately prior to the reporting period. The City will monitor the implementation of its programs and the overall effectiveness by measuring and reporting the data discussed in the individual Minimum Control Measure sections discussed above. The City will regularly evaluate both current conditions and BMP effectiveness, and as appropriate update BMPs and measurable goals to achieve the objective of meeting water quality standards to the Maximum Extent Practicable. If after implementing the minimum control measures there is still a water quality impairment associated with discharges from the City's MS4, it may be necessary to expand or better tailor existing BMPs. Form and Content of Annual Report Guidance had not yet been provided as to the specific form and content of the annual report. Because the City is required to keep records for five years and due to the intent of the reporting requirements, the annual report will focus on a summary of progress and discuss any changes to the SWMP to be implemented in meeting the Maximum Extent Practicable standard. The focus will be to clearly show progress, to discuss program adjustments, and respond to challenges in implementing the SWMP. Reporting Data compiled for each measurable goal will be compiled and reviewed. Significant variance from target dates will be assessed and discussed in annual reports to the RWQCB. Feedback from staff, permittees, developers, stakeholders, etc. will be used to modify BMPs or measurable goals, as appropriate; the basis for any changes will be included in the following annual report. Pursuant to the "General Permit, " the City will retain storm water records for five years. The Public Works Department will be responsible for implementing substantial elements of the SWMP and will be maintaining records to the extent possible for five years. These records will be the source of compiled data contained in the annual report.
