lFer'XIMORC <br /> of TPH G was 3 6 m Appendix C contains the laboratory�g APIA results and figure showing the <br /> soil stockpile sample locations Also, based upon the defined lateral and vertical extent of <br /> petroleum hydrocarbon impacted soils associated with the three former 5,000 gallon USTs, it <br /> is believed that the soil removed during the installation of the 15,000 gallon UST is not <br />' impacted with petroleum hydrocarbons It is proposing to consider Stockpile 2 to be non- <br /> contaminated and thus the soil will be spread evenly over the area where it is currently <br />' stockpiled No further activities are proposed for these soils <br /> 3 4 3 Drummed Waste <br /> A total of 43, 55-gallon drains are currently stored on the site (see Figure 5) Of these <br /> drums, 37 drums contain soil generated during previous site investigations, two drums contain <br /> liquid, reported to be water generated during the purging and development of the groundwater <br />' monitoring wells on site, and four drums are empty It is proposed to characterize the <br /> contents of the drums and dispose of the waste accordingly <br />' tMTo characterize the druammed soil, it is proposed to empty all of the drums andform a <br /> gle stockpile The stockpile wall be placed on impermeable bermedlastic sheeting, and <br /> P g, <br /> will remain covered until characterization has been completed It as estimated that a total of <br /> 12 cubic yards of soil are presently drummed The resulting stockpile will be sampled to <br />' determine any potential hazardous cratena From the stockpile soil, one composite sample <br /> will be collected, and analyzed by a certified laboratory for TEN and TPH as JP-4 <br />' het fuel If soil contaminant concentrations are below 00 mg/kg for TP th the absence �o <br /> of BTEX compounds, the soil will be spread and left on s e present location of the <br /> r <br /> To characterize the drummed liquid, each drum will be sampled with the samples <br /> being analyzed for TPH-G, BTEX TPH as JP4 het fuel Following the receipt of the <br /> analytical results, Versar will either dispose of the water at an appropriate off-site facility or <br /> request permission from the San Joaquin PHS/EM to dispose of the water on site The <br /> empty drums currently on site and any that are created during on-sate disposal activities will <br /> be used dunng Versaa's investigation to store soil or liquid investigation derived wastes <br /> it <br />
