CC 2015-02-10_11b So Cal Gas Co Enhancement ProjectMEMORANDUM
TO: CITY COUNCIL
FROM: GEOFF ENGLISH, PUBLIC WORKS DIRECTOR
SUBJECT: PRESENTATION ON ,SOUTHERN CALIFORNIA GAS COMPANY
PIPELINE SAFETY ENHANCEMENT PROJECT AND CONSIDERATION
OF A WAIVER OF THE FIVE YEAR PAVEMENT TRENCH CUT
PROHIBITION
DATE: FEBRUARY 10, 2015
RECOMMENDATION:
It is recommended the City Council receive and comment on a presentation from
Southern California Gas Company staff about the proposed Pipeline Safety
Enhancement project; and approve a waiver of the Five Year Trench Cut Prohibition on
new pavement for sections of West Branch Street and El Camino Real.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The City will receive a reimbursement from SoCalGas in the amount of $1,394 for
previous expenses incurred to purchase a Caltrans encroachment permit for the Brisco
Undercrossing paving project. There are no financial impacts of the proposed
recommendations. All project expenses will be paid by Southern California Gas
Company (SoCalGas). The fiscal impacts of SoCalGas cutting into recently paved
street will be offset by larger restoration areas.
BACKGROUND:
Following the 2010 natural gas pipeline rupture· in San Bruno, the California Public
Utilities Commission (CPUC) ordered the State's four natural gas transmission pipeline
operators -Pacific Gas & Electric, Southwest Gas and San Diego Gas & Electric, as
well as Southern California Gas Company --to develop plans to replace or pressure test
all natural gas transmission pipelines that have not been tested to modern standards.
The intent was to adopt new safety and reliability regulations for natural gas pipelines,
based upon lessons learned for the 2010 San Bruno incident.
In response, SoCalGas submitted a Pipeline Safety Enhancement Plan (PSEP) to
implement the directives of the Commission to the CPUC. The SoCalGas plan was
approved by the CPUC in June 2014. The approved plan is intended to enhance
SoCalGas' pipeline system safety. This work is part of a system-wide effort to further
enhance the safety of pipelines throughout the State. The CPUC approved plan
identifies various SoCalGas pipeline sections throughout the statewide system that

have not been pressure-tested, or for which there is no record of a pressure test, and
requires that they be pressure-tested or replaced.
ANALYSIS OF ISSUES:
SoCalGas will be pressure testing or replacing pipelines at various locations in Arroyo
Grande. SoCalGas will be notifying customers via a public outreach campaign, when
pressure testing or replacement activity is coming to their neighborhood and will make
every effort to minimize impacts on the community. The Pipeline Safety work in Arroyo
Grande is scheduled to begin in early 2015. The work is expected to take 10 to 12
weeks. A description of the project and the project routing is attached (Attachment #1)
and will be discussed by SoCalGas representatives in the form of a presentation about
the project.
City staff has recommended the following conditions and mitigations for the impacts of
this SoCalGas project.
1. Secure a separate encroachment permit from the City of Arroyo Grande, with all
necessary attachments, including construction plans, traffic control plans, and
emergency contact information.
2. Reimburse the City of Arroyo Grande $1,394 for the cost to purchase a Caltrans
encroachment permit for the Brisco Undercrossing paving project. (This actual
financial impact resulted when So Cal Gas informed the City previously about the
routing of the project under the Brisco underpass. Paving work schedule for the
summer of 2014 was canceled in anticipation of the trenching work to be
performed by SoCalGas. A new Caltrans encroachment permit will be required
at an additional cost.)
3. Meet all City standards for construction in the public right of way, including
trench repair requirements along with full-lane width paving for any disturbed
area road sections.
4. Confirmation of environmental impact determination through a California
Environmental Quality Act (CEQA) review process, or arrangement of an
environmental review process with the City of Arroyo Grande serving as the lead
agency, funded by SoCalGas. (According to SoCalGas, environmental review
has been completed, however, CEQA does not apply to the project because the
proposed activity is either statutorily exempt pursuant to Public Resources Code
§21080.21 or categorically exempt pursuant to either/or §15301 (Class 1),
§15302 (Class 2) and §15304 (Class 4) of the State CEQA Guidelines.)
5. Fund the cost of% day inspection services for a City hired Inspector on all active
days of work within the City boundaries.

SoCalGas has agreed to the above stated conditions. Staff also explored the potential
opportunity to install "purple pipe" for reclaimed water in the same or adjacent trench. In
accordance with the agreement between SoCalGas and the CPUC for the
administration of the PSEP program, project enhancements are not allowed with this
project. According to SoCalGas, only testing and remediation of the lines to assure the
public safety are permitted expenses.
Additionally, staff is requesting that the City Council approve a waiver of the five year
trench cut prohibition on new pavement for the sections of West Branch Road and El
Camino Real. Resolution 3819 regarding the Pavement Cut Policy (Attachment #2)
prohibits trenching into road surfaces that have been repaved within the past five (5)
years. (Attachment #3) The policy allows the Public Works Director to lift this restriction
for emergency, safety and utility repairs or work mandated by the State, however given
the magnitude of the proposed work, staff is requesting the Council to waive the five
year trenching restriction. Staff has also requested, and SoCalGas has agreed, to
complete full lane pavement repair in this area. Typical restoration work, in non-
moratorium street, would be limited to the trench area.
ALTERNATIVES:
The following alternatives are provided for the Council's consideration:
• Add additional conditions to SoCalGas for the proposed Pipeline Safety
Enhancement Plan project;
• Provide direction to staff.
ADVANTAGES:
This project will improve the safety and reliability of the natural gas pipelines routed
through the City of Arroyo Grande.
DISADVANTAGES:
This project will cause temporary traffic disruptions for Arroyo Grande motorists and will
cut into recently constructed road paving on West Branch Road and El Camino Real.
ENVIRONMENTAL REVIEW:
The project is statutorily exempt pursuant to Public Resources Code §21080.21 or
categorically exempt pursuant to either/or §15301 (Class 1), §15302 (Class 2) and
§15304 (Class 4) of the State CEQA Guidelines.
PUBLIC NOTIFICATION AND COMMENTS:
The agenda was posted at City Hall on Thursday, February 5, 2015. The agenda and
staff report was posted on the City's website on Friday, February 6, 2015. No public
comments were received as of the time of preparation of this report.

ROUTING AND PROJECT DESCRIPTION (Provided by SoCalGas)
SoCalGas first plans to hydrostatic pressure test approximately 4,670 feet of existing
pipe along W. Branch St, starting at N. Oak Park and ending east of the Rodeo Dr.
Hydrostatic pressure testing is a process that uses water to exert pressure on a pipeline
at levels greater than its usual operating pressure to assess its soundness, often
referred to as its integrity. The pipeline segment to be tested on W. Branch St. will be
temporarily removed from service and excavations will be dug at both ends of the
segment to expose the pipeline. SoCalGas will be responsible to ensure that the
natural gas inside will be safely and legally vented.
Water will be pumped into the segment and the pressure will be increased to a level
greater than the pipeline's usual operating pressure. After holding the increased
pressure for eight hours or more, the test will be complete and the water will be drained
into water tanks and recycled, reused, or disposed of in accordance with applicable
regulations and local requirements. Some traffic may be impacted in this section, but
will be marked with traffic cones and signs. Nearby residents may hear some work-
related noise. Construction crews will be working from 7 am to 5 pm Monday through
Friday. The work is expected to take eight to ten weeks.
The next section of Pipeline Safety work is scheduled to begin in early April 2015. A
3,266 foot section of pipe will be replaced starting south of Brisco Rd along El Camino
Real and ending south of E. Grand Ave. This pipeline replacement activity involves
installing new pipe parallel to the path of the existing pipeline. Next, the existing pipeline
is taken out of service and the natural gas is safely removed from it. Then, the new
pipeline section is connected to the distribution system and brought into service. Traffic
may be impacted in this section, but will be marked with traffic cones and signs.
People passing by the work site may see an excavation, equipment, and traffic control
signage as well as trucks and other vehicles. The nearby community may also hear
some work-related noise. Construction crews will be working from 7 am to 5 pm Monday
through Friday. The work is expected to take 10 to 12 weeks.
SoCalGas also plans to replace a 7 ,200 foot section of pipe starting near the
intersection of El Camino Real and E. Grand Ave and ending near the intersection of
Century Lane and Los Berros Rd. The construction activity is scheduled to begin early
June 2015 and work is expected to take about ten to twelve weeks. Like the
replacement project along El Camino Real, this pipeline replacement activity involves
installing new pipe parallel to the path of the existing pipeline. Next, the existing
pipeline is taken out of service and the natural gas is safely removed from it. Then the
new pipeline section is connected to the distribution system and brought into service.
Construction crews will be working from 7 am to 5 pm Monday through Friday.
