Smith Techno!W SITE SAFETY PLAN <br /> FACILITY BACKGROUND <br /> In March 1990, one 1,500-gallon unleaded gasoline underground storage tank (UST), one <br /> unleaded gasoline UST of unknown size, and all associated piping and dispensing <br /> equipment were removed and transported off-site. Laboratory analysis of soil samples <br /> collected from beneath the former 1,500-gallon UST location indicated the presence of <br /> detectable concentrations total petroleum hydrocarbons. Discoloration of soil and a <br /> petroleum hydrocarbon odor were noted in the field. After the tanks were removed, the <br /> areas of the former tanks were backfilled. <br /> WORK PLAN <br /> Task One: <br /> Supervise the installation of two soil borings to depths of approximately 30 feet. Two <br /> soil samples and one groundwater sample will be collected from each boring from <br /> areas which exhibit physical indications of contamination. Samples will be analyzed' <br /> for BTEX (EPA Method 8020), TPHg (EPA Method 8015 Modified), oxygenate fuel <br /> additives (EPA Method 8260), and total lead. <br /> PAGE 4 <br /> I <br />
