The parcel is the former site of a gasoline station. The former underground <br /> fuel tanks were removed in the early 1980s, prior to the requirement to collect <br /> confirmation soil samples as part of the tank closure process. As a result, it remains <br /> ' unknown whether the tanks might have leaked to impact the surrounding soil. This Work <br /> Plan is intended to collect soil samples from under the original tank pit to determine if a <br /> leak occurred. <br /> 1.1 SITE BACKGROUND <br /> The parcel currently is the site of C&C Auto Repair, but was originally developed as a <br /> Sunland gasoline station in 1965. The gasoline station ended operation sometime <br /> between 1975 and 1977, and the current owner purchased the site shortly thereafter. The <br /> current owner reports that he removed the underground fuel tanks in the early 1980s and <br /> they consisted of two 8,000-gallon gasoline tanks and a 4,000-gallon diesel tank. At the <br /> time, there was no requirement to collect confirmation soil samples, and so it remains <br /> unknown whether the former tanks might have leaked. The original gasoline station <br /> building, and the dispenser pump islands are still intact, and the location of the original <br /> ' tank pit is indicated by an area of subsided asphalt near the pump islands (see attached <br /> site map). <br /> ' 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc.
