was determined that secondary containment far exceeds the I 10% volume of the used oil tank. The secondary containment does not have a drain system, and storm water must be pumped out (See Inspection Data Sheet attached). Used Tank Integft Test 1-04 visible sign of amX=ent or -iast leakagtfromAhia-w-wle- L# oil tank. On 9/29/2008 a 5 PSI pressure test was applied to the tank and the two foot of product in the used oil tank. Jim Thorpe Oil provide the manpower and equipment to make the tank air tight and pressurize the tank. The tank was pressurized slowly with a visual check of all welds and piping as the pressure was increased to 5.0 PSI (See inspection data sheet attached for details of the test). Two air leaks were found by soap solution and repaired by tightening access bolts and a pipe plug. The tank remained under 5 PSI pressure for 2.5 hours without any pressure loss. No stress cracks or welding maintain a 5.0 PSI on the tank (See Inspection Data Sheet attached).
