LFR Inc. <br /> 1.0 INTRODUCTION <br /> This Work Plan presents objectives, methods, and procedures to conduct additional <br /> investigation of petroleum-affected groundwater at the SFPP, L.P. Stockton Terminal, <br /> located at 2947 Navy Drive, Stockton, California ("the site"; Figures 1 and 2). This <br /> Work Plan has been prepared on behalf of SFPP, operating partnership of Kinder <br /> Morgan Energy Partners, L.P. (SFPP), by LFR Inc. (LFR) for submittal to the Central <br /> Valley Regional Water Quality Control Board (RWQCB). <br /> This Work Plan, and subsequent investigation, is the result of requests made by <br /> RWQCB personnel during the June 17, 2009 meeting between the RWQCB, SFPP, <br /> and LFR. <br /> 1.1 Site Setting <br /> The site is located east of Navy Drive, in an industrial portion of Stockton, California <br /> (Figure 1), and consists of a petroleum pipeline manifold area operated by SFPP. The <br /> site is located south of the Time Oil and Tesoro facilities and north-northwest of the <br /> NuStar (formerly ST Services) and former Unocal facilities, all of which contain <br /> several aboveground petroleum storage tanks (Figure 2). <br /> 1.2 Summary of Previous Investigation Results <br /> SFPP has conducted several subsurface investigations since the early 1990s to evaluate <br /> soil and groundwater conditions beneath the site. These investigations have included <br /> the installation and monitoring of eight shallow-groundwater (A-zone) and two deeper- <br /> groundwater (B-zone) monitoring wells (SP/M-1 through SP/M-10). Monitoring well <br /> SP/M-2 was destroyed during July 1992 in accordance with San Joaquin County <br /> Environmental Health Department (SJCEHD) guidelines. The remaining nine wells are <br /> used for semiannual and/or annual groundwater monitoring and sampling in <br /> accordance with Monitoring and Reporting Program Number R5-2005-0815. <br /> 2.0 INVESTIGATION OBJECTIVES AND APPROACH <br /> 2.1 Objectives <br /> The objective of the investigation described in this Work Plan is to assess the vertical <br /> extent of petroleum-affected groundwater in the B- and C-zone depth intervals near <br /> manifold-area monitoring well SP/M-9, particularly in relation to regional petroleum <br /> impacts from off-site sources. <br /> wp-Stockton-2009 H C Zone Well Install—FINAL.doc Page 1 <br />
