The. <br /> samples will :be collected. At various depths from beneath. the 00a:,. <br /> fuel dispenser island and :associated piping. <br /> 4.1.1 Soil Borings: Soil borings willbe drilled: <br /> various locations on the site to�:obtain sail samples. :Two vertical <br /> Soil borings will be drilled on either side of the group of three <br /> gasoline (and possibly diesel) UST s to approximately 15 feet below <br /> site grade (BSG) . one soilboring each will, be drilled on an angle <br /> L4 <br /> calculated to reach approximately three feet beneath the bottom of <br /> the fill-end (approximately 15, feet BSG) df: each: Of the three USTS. <br /> o" each soil boring w il be drilled adjacent to each fuel. <br /> disp6rttet Island. to approximately 5 feet 1$0 Six :soil borings <br /> will be drilled to. approximately 5 feet hear the <br /> product' lines. <br /> onesoil boring will :be: drilled to approximate ly 10 feet near the <br /> waste-oil.
