PMR <br /> bond <br /> 2. New Hazardous Waste Tank System Tightness Testing Protocols <br /> The following waste tank system tightness testing protocols were developed to verify all three systems' <br /> tanks do not leak even when completely full, and were emailed to SJCEHD for review. <br /> 2.1 Used Oil Tank System Testing <br /> 1. The steel tank will be filled to the top. It cannot be filled above the top or fluid would flow out of the <br /> vent pipe there. <br /> 2. The rope oil collection system will be turned off so no additional oil can enter the tank. <br /> 3. An aperture on the top of the tank will be opened and a measurement will be taken there with <br /> date- and time-stamped photo documentation. <br /> 4. At least 24 hours later, the level of fluid at the aperture on the top of the tank will be measured <br /> again with date-and time-stamped photo documentation. <br /> 5. Two fluid level measurements at the tank top aperture over a 24-hour period will verify the tank <br /> does not leak. <br /> 6. The PVC pipe that conveys used oil from the rope oil system box to the used oil tank is <br /> considered inherently leak proof because: <br /> a. It is open to the atmosphere and therefore under no pressure. <br /> b. It is located above the tank and conveys fluid by gravity and is only ever partially full. <br /> 2.2 Poly Tank System Testing <br /> 1. The poly tank will be filled to the top. The tank cannot be filled above the top or fluid would flow <br /> out of the J-pipe vent there. <br /> 2. No additional fluid will be allowed to enter the tank via the conveyance piping from the steam <br /> cleaning room and a sign will be posted in the room to that effect. <br /> 3. The level of fluid in the poly tank will be automatically measured by the level indicator located <br /> beside the tank, and a date- and time-stamped photo will be taken for documentation. <br /> 4. At least 24 hours later, the level of the fluid in the poly tank will be read off the level indicator, and <br /> a date- and time-stamped photo will be taken for documentation. <br /> 5. Two fluid level readings over a 24-hour period will verify the poly waste tank does not leak. <br /> 6. The PVC pipe that conveys oily water from the steam room to the poly tank is considered <br /> inherently leak proof because: <br /> a. It is open to the atmosphere and therefore under no pressure. <br /> b. It is located above the tank and conveys fluid by gravity and is only ever partially full. <br /> 11189093FIorido-2 2 <br />
