Q <br /> A TC Associates SITE SAFETY PLAN <br /> FACILITY BACKGROUND <br /> In July 1991, RESNA personnel witnessed the removal of the 2,000-gallon regular gasoline <br /> UST and the associated product line. No holes were observed in the UST. Soil samples <br /> were collected beneath the UST and product Iine and contained elevated concentrations of <br /> petroleum hydrocarbons. Groundwater monitoring wells were installed in 1991 and a <br /> groundwater monitoring program has been in place since October 1991. In January and <br /> February 1996, SECOR International Incorporated (SECOR) advanced ten soil borings at <br /> the site. Soil samples and grab groundwater samples were collected from the borings. Only <br /> one soil sample contained detectable concentrations of petroleum hydrocarbons at low <br /> levels. Groundwater samples collected from borings S112 and SB26 contained elevated <br /> concentrations of petroleum hydrocarbons and trace amounts of free product. <br /> WORK PLAN <br /> Task One: <br /> Supervise the advancement of up to ten soil borings to 15 feet b s. Two soil samples <br /> g P <br /> and one groundwater sample will be collected from each boring from areas which <br /> exhibit physical indications of contamination. Soil samples will be analyzed for <br /> BTEX (EPA Method 8020) and TPHg and TPHd (EPA Method 8015 Modified). <br /> Groundwater samples will be analyzed for BTEX, TPHg, TPHd, and oxygenate fuel <br /> additives (EPA Method 8260). <br /> PACE 4 <br />
