During this meeting, we <br /> discussed the cleanup status of the Holt Petroleum Pipeline Release Site (site), which is at <br /> 3851 South Whiskey Slough Road in Holt, San Joaquin County. Kinder Morgan Energy Partners <br /> L.P. through its operating partner SFPP, L.P. (KMEP) owns and operates an underground <br /> petroleum pipeline network that includes the 10-inch diameter section of pipeline that lies within <br /> the leased easement between Whiskey Slough Road and Trapper Slough. KMEP is conducting <br /> cleanup as a result of a February 1986 product release from the pipeline. The pipeline is buried <br /> about five feet below ground surface (bgs) and generally transports various grades of refined <br /> petroleum fuel from Concord to Stockton and on to the Bradshaw Terminal in Sacramento. <br /> The contaminants of concern (COC) include benzene, toluene, ethylbenzene, xylene and total <br /> petroleum hydrocarbons in the gasoline (TPHg) and diesel (TPHd)ranges. The fuel oxygenate <br /> methyl tertiary butyl ether(MTBE) is present in the groundwater as a pollutant but is also present <br /> at about the same concentration in Trapper Slough, the neighboring losing stream. KMEP <br /> reported that during the sampling event conducted on 3 June 2003, monitoring well N-15, near <br /> the source area contained 2,400 µg/1 of benzene and 5,200 µg/1 of TPHg. Monitoring well N-7 in <br /> the source area contained 9,100 µg/1 of benzene and 31,200 µg/1 of TPHg. A large portion of the <br /> source area mass remaining in groundwater is bound within fine-grained material and a peat soil <br /> lens that slowly releases pollutants. The highest concentration of dissolved pollution southeast of <br /> South Whiskey Slough Road is at monitoring well N-17, which has 330 4g/1 of benzene and <br /> 1,100 µg/1 of TPHg. The pollutant plume is monitored by two downgradient wells, N-18 and <br /> N-19, which continue to have no detectable levels of any of COCs. <br /> California Environmental Protection Agency <br /> ��Recycled Paper <br />
