The site is <br /> presently unoccupied, and the property is fenced. The facilities <br /> consist of a metal and stone building containing space for an <br /> office and three service bays, two pump islands with associated <br /> canopy, two 10, 000-gallon underground gasoline storage tanks, and <br />' small sheds. <br /> IOn June 18, 1990, a 550-gallon underground waste-oil <br /> storage tank was removed. The steel tank was found to have holes <br /> and to have leaked (Kaprealian Engineering Company Report, <br /> 9/24/90) . An Unauthorized Release Report was filed with the <br /> California Water Quality Control Board, Central Valley Region. <br /> Following tank removal, an excavation that measured 9' <br /> wide, 121 long, and 14 .5' deep was made to remove oil-contaminated <br /> soil. Not all oil-contaminated soil was removed, due to the <br /> proximity of the gasoline storage tanks. The excavation was <br /> backfilled with pea gravel. <br />
