Dear Mr. Smith,
SITE CLEANUP PROGRAM: UNOCAL (CHEVRON) SAN LUIS OBISPO TANK FARM, 276
TANK FARM ROAD, SAN LUIS OBISPO, SAN LUIS OBISPO COUNTY – CONCURRENCE
WITH THE FINAL REMEDIAL ACTION PLAN (MARCH 31, 2015)
Central Coast Regional Water Quality Control Board (Water Board) staff is providing this letter
to indicate our concurrence with the Final Remedial Action Plan, San Luis Obispo Tank Farm
Final RAP) dated March 31, 2015, which was prepared by Avocet Environmental, Inc. on
behalf of Chevron. Chevron adequately addressed Water Board staff comments related to water
quality issues in the previous August 13, 2014 Revised Remedial Action Plan (Revised RAP) for
the San Luis Obispo Tank Farm (Tank Farm) property. The Final RAP addresses comments on
the Revised RAP that the following agencies provided to Chevron and Water Board staff1: the
San Luis Obispo County Air Pollution Control District (APCD), County of San Luis Obispo
Health Agency, Public Health Department (PHD), and California Department of Fish and Wildlife
CDFW). Copies of these agencies’ comments and Chevron’s associated responses are
included in Appendix N of the Final RAP. Based on information provided to Water Board staff
by Chevron and staff from these agencies, it is our understanding that staff from the APCD,
PHD, and CDFW are satisfied with responses to their respective comments that Chevron
incorporated into the March 31, 2015 Final RAP.
Background
Chevron prepared the Final RAP (as well as previous versions) to address the cleanup of
constituents associated with petroleum hydrocarbons at the Tank Farm property. The Final
RAP includes the proposed scope of work for the remediation portion of Chevron’s multi-phased
1 On most Site Cleanup Program sites, the Water Board is solely responsible for approving RAPs. The typical
process for RAP approval is as follows: Water Board staff notifies the public about the existence of a draft RAP, and
solicits comments on the document. Water Board staff subsequently responds to comments and requires the
responsible party (RP) to make any necessary changes to the RAP. The RP cannot initiate cleanup activities until
Water Board staff agrees that the final RAP appropriately complies with the required changes. However, due to the
size of the Tank Farm property, the variety of proposed remediation activities, the various permits Chevron must
obtain to conduct the proposed activities, and the existence of the Surface Evaluation, Remediation, and Restoration
Team (SERRT), all SERRT members were given the opportunity to review and comment on all documents
associated with the Tank Farm remediation activiities, up to and including the March 31, 2015 Final RAP.

remediation, restoration, and development (RRD) project at the Tank Farm property. Chevron
initially submitted a Draft RAP to the federal, state, and local agencies and municipalities
participating in the SERRT in 2007. Chevron modified this Draft RAP (also in 2007) to address
comments from SERRT members. Water Board staff included a public notification of the
revised Draft RAP - - and solicitation for public comment - - along with the Draft Environmental
Impact Report (EIR) for Chevron’s RRD project, which was released for a 45-day public review
period on June 20, 2013. As the lead agency 2 for the California Environmental Quality Act
CEQA) process, the City of San Luis Obispo received comments on various topics addressed
in the Draft EIR. Responses to some of the comments resulted in changes to the Draft EIR.
Water Board staff did not receive any comments on the revised 2007 Draft RAP; however,
Chevron modified the document to conform to information contained in the Final EIR (FEIR,
dated December 28, 2013). Chevron therefore provided Water Board staff with a Revised
Remedial Action Plan dated May 15, 2014 (May 2014 Revised RAP). Water Board staff
reviewed and commented on this document and Chevron incorporated responses to our
comments into the August 13, 2014 Revised RAP.
Based on the variety of proposed remediation activities and associated permits and approvals
Chevron must obtain to accomplish site remediation, staff from the W ater Board and Chevron
provided SERRT members with an additional opportunity to review and comment on Chevron’s
plan for cleanup at the Tank Farm property. In a September 9, 2014 email from Chevron to
SERRT members, Mr. Rik Williams invited the SERRT to review the August 13, 2014 Revised
RAP located on the GeoTracker database and provide comments to Water Board staff by
September 23, 2014. As noted above, copies of SERRT members’ comments and Chevron’s
associated responses are included in Appendix N of the March 31, 2015 Final RAP.
Water Board staff appreciate Chevron’s efforts to finalize the RAP and arrive at this remediation
phase of its multi-phased, multi-year RRD project, and we encourage Chevron to proceed with
remediation activities as soon as possible. W e look forward to the net environmental benefits
that cleanup activities described in the Final RAP will accomplish.
If you have any questions, please contact Water Board staff Diane Kukol at (805) 542-4637
Diane.Kukol@waterboards.ca.gov) or Angela Schroeter at (805) 542-4644.
Sincerely,
for Kenneth A. Harris Jr.
Executive Officer
2 Because the Tank Farm property is outside the city limits of San Luis Obispo - - but may be annexed into the City in
the near future - - the City and County of San Luis Obispo were the co-lead agencies for preparing the EIR for
Chevron’s overall RRD project. Based on a Memorandum of Understanding concerning each jurisdiction’s role in the
CEQA process (and recorded by the San Luis Obispo County Clerk on February 7, 2013), the City became the lead
agency for FEIR certification and will continue in this role for future development after annexation occurs. The
County is the lead agency for the project phases that deal with remediation, restoration, and grading in preparation of
development. In the event annexation does not occur, the County will assume lead agency status for the
development phase of the project as well.
