(SFPP), an operating partnership of Kinder Morgan Energy Partners, <br /> L.P. for the Stockton Junction at the intersection of Inland Drive and Jacobs Road in Stockton <br /> (site). The Work Plan proposes to initially install four or five temporary piezometers to gather <br /> groundwater flow direction information. Based on the concentrations of grab groundwater <br /> samples from the temporary piezometers and flow direction, SFPP will continue to step out with <br /> borings to collect additional grab groundwater samples to determine the lateral extent of <br /> pollution. <br /> We have the following comments on the Work Plan: <br /> 1. Board staff concurs that additional soil sampling is not necessary based on the <br /> confirmation soil samples collected from the excavation area after SFPP over-excavated <br /> on 21 November 2001. <br /> 2. The Work Plan does not propose to analyze for lead stating that the analysis is not <br /> required because lead concentrations in soil are representative of background. We <br /> concur, however, the concentrations in soil may.not show whether lead from gasoline <br /> products entered the groundwater. Therefore, SFPP must analyze the proposed grab <br /> groundwater samples for dissolved lead by EPA Method 7241. <br /> 3. The Work Plan proposes to analyze grab groundwater samples for methyl tertiary butyl <br /> ether, but not other fuel oxygenates. SFPP must analyze the grab groundwater samples <br /> for the full suite of oxygenates by EPA Method 8260 to determine if they were released. <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br /> The energy challenge facing California is real.
