PMR <br /> bond <br /> 3. Tank Tightness Testing Results <br /> On May 12, 2020, each of the three tanks was filled to the top. In the case of the used oil tanks, the rope <br /> oil collection system was turned off so that no more used oil could enter the tanks. In the case of the poly <br /> tank, steam cleaning of machine parts was suspended to prevent further oily water from entering the tank. <br /> Fluid level measurements were then taken as follows: <br /> • A steel tape was used on the Furnace A-B used oil tank to measure the fluid level at 1 inch from the <br /> top of the aperture on the top of the tank at 16:54 hours. <br /> • A steel tape was used on the poly tank manhole to measure the fluid level at 3 inches from the top of <br /> the lip at 16:51 hours. <br /> • A steel tape was used on the Furnace C used oil tank to measure the fluid level at 1.75 inches from <br /> the top of the aperture on the top of the tank at 17:19 hours. <br /> On May 14, 2020, fluid level measurements were taken again as follows: <br /> • A steel tape was used on the Furnace A-B used oil tank to measure the fluid level at 1 inch from the <br /> top of the aperture on the top of the tank at 09:22 hours. <br /> • A steel tape was used on the poly tank manhole to measure the fluid level at 3 inches from the top of <br /> the lip at 09:35 hours. <br /> • A steel tape was used on the Furnace C used oil tank to measure the fluid level at 1.75 inches from <br /> the top of the aperture on the top of the tank at 09:26 hours. <br /> Documentation of the above leak detection measurements is provided in Attachment 1. <br /> Based on the measured results of the tank leak detection testing, all three tanks, the two used oil and the <br /> one poly tank, and their associated hazardous waste-containing systems, have been shown to not leak. <br /> 4. Hazardous Waste Manifest <br /> The Hazardous Waste Manifest 014082521 FILE for disposal of the oily water in the subject tanks is <br /> included in Attachment 2. <br /> 5. Certification of the Tank Systems <br /> Based on the results above as well as the information provided in the referenced reports, as required by <br /> 40 CFR 265.192(a) and 22 CCR 66265.192(a), the Tank Systems have been found to have sufficient <br /> structural integrity and are acceptable for the transferring of hazardous waste. The tanks and containment <br /> systems are adequately designed to achieve the requirements of the applicable regulations, and each of <br /> the entire subject tanks and their systems are tight. This certification is valid for five years only as long as <br /> 11189093FIorido-2 3 <br />
