embedments in the concrete block wall have been sealed with a suitable sealant to prevent leakage. The G-1fxXxS�tee Ki to any liquid, but concrete has a very low rate ofpermeability. Any spills would be discovered long before diesel or used oil could penetrate the 8" concrete block wall or the concrete floor. All penetrations are caulked with sealant. The block wall containment area will hold the largest tank (10, 000 Gals.) with 0. 39 feet of fteeboard. By observation, it 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 and Mathcad Sheet attached). Piping Condition Tank piping is in very good condition. Vacuum line is I Y2" schedule 40 about 4'long. Pressure side is I Y2 "single wire oil resistant rubber hose to top oftank than 131? "fillpipe ofschedule 40pipe. Volume 389 cubic inches. 1. 7 gals. The drain or unloading line was tested with the tank -for a pressure of 5 psi. with no leaks. Used Oil Tank Integri1y Test On the date of this inspection, there was no visible sign of any current or past leakage ftom, this waste 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 bv soap solution and repaired by tightening access bolts and a pipe plug. The tank - remained under 5 PSI pressure for 2.5 hours without anv pressure loss. No stress cracks or welding Monomw-,i Jwfiiw� t -1r4- 2j MeMncressure. No make-ut) airwas need during the test to aintain a 5.0 PSI on the tank (See InsT)ection Data Sheet attached). Used Oil Tank Anchorage Design *on inspection of the used oil tank. it was observed that the used oil tank was not constructed with ?.rY-*hoRwQmm'b�- proper �anchmravzc system. was designed bv the author to mevent ontainn-�ient tlo�orA propet movement of the tank as directed bv the 1997 California Building Code (See attached drawing and calculations).

On the date of this insmetion and with the seismic anchor retro fit. this used oil tank meets or exceeds the reauirements of both the State and Countv codes. 1. Ervin Rifenbum.
