t• 95-11-01 ' On 14 May 1995, the pavement and soils overlying the UST and fill pipes associated with the UST was removed and the top of the UST was exposed by Banks & Co. All product piping was purged with nitrogen and water prior to disconnecting the piping from the UST ports. Following the removal of the fill pipes, residual contents were noted in the USTs prior to rinsing. On 15 May 1995, this product was siphoned into a vacuum truck prior to rinsing the ' UST and the UST was triple rinsed using a pressure washer. Approximately, 400-gallons of waste oil product/diesel/gasoline/ rinseate, generated during rinsing, was siphoned into a vacuum truck and manifested to Petroleum Recycling Corporation (PRC) in Patterson, ' California for recycling. Reportedly, an additional 90 to 100-gallons of this mixture was manifested, and transported for recycling by San Joaquin Delta College. A copy of the ' uniform hazardous waste manifest, indicating the volume of material transported by PRC and showing signatory acceptance by this facility is attached to this report. On 16 May 1995, the appropriate amount of dry ice was placed into the UST; the ' Lower Explosive Limit (LEL) and oxygen content were monitored. When acceptable levels for LEL and oxygen were reached, each of the USTs were removed. Tank Nos. 1 and 2, The UST was observed to have had four small holes and was moderately pitted when ' removed; some exterior oil product was noted on the side of the UST. T-1 measured nine by six feet and had an approximate volumetric capacity of 2,000-gallons; T-2 and T-3, each measured 12 by four (4) feet and had an approximate volumetric capacity of 1,000-gallons; T-4 measured six (6) feet by (4) feet and had an approximate volumetric capacity of 500-gallons;Tank Nos. 1,2,3&4 were designated 39-1219- 01,39-1219-02,39-1219-03, and 39-1219-08, respectively,and were marked accordingly prior ' to transport to West Coast Equipment in Turlock, California. Upon inspection of the four tanks, the following observations were made: ' o T-1; Fair Condition, Rusted, One 1-inch Diameter Hole o T-2; Fair Condition, Rusted, One 1/2-inch Diameter Hole ' o T-3; Good Condition, Rusted, No holes ' o T-4; Fair Condition, Rusted, No Visible Holes ' During removal of the USTs and the underlying concrete support structures, all of the excavated soils were temporarily stockpiled onsite. Two separate stockpiles, designated SP-1, containing approximately 75 cubic yards and SP-2, containing approximately 125 cubic ' yards. The former locations of the USTs are presented on the attached tank removal and soil sample location map (See Drawing No. 1). 2 ' MOORE SERVICES, INC.
