<br /> <br />Wood Environment & Infrastructure Solutions, Inc. 275 Gal. Waste Antifreeze Tank <br />ambient temperature ethylene glycol vapors through electrostatic <br />discharge is improbable; lightning protection (grounding rod) is not <br />required. <br /> <br />The tank was delivered new and fully assembled to the site in September <br />2011. The tank is estimated to have an approximate 10-15 year service <br />life. The tank manufacturer provided a 3-year warranty for this tank. <br /> <br />The tank is bounded by a compressor shed on the west and further <br />protected from vehicular traffic and physical damage by two concrete <br />block structures on its east side. See Attachment 1 Photolog. <br /> <br />Piping and ancillary equipment (pumps) 66265.192(k)(2)(C&D): <br />Piping Material of Construction: 3/4-inch rubber hose discharge line <br />and 3/4-inch similar suction line; exact hose specifications are unknown, <br />but the hosing is consistent with industry standards and shows no signs of <br />swelling or cracking. <br /> <br />Piping Diameter: 3/4-inch <br /> <br />Pump location(s): The pump is rigidly mounted on the wall just inside the <br />roll-up door. The discharge hose runs through the exterior wall, into and <br />through a compressor shed, and into the top of the adjacent tank. <br />Grommets protect the hosing as it passes through each structure. The <br />hosing is connected to metal pipe and a ball valve forming two right angle <br />turns before entering an aftermarket tank fitting. The suction hose also <br />runs through the exterior wall with enough length to hang a couple loops <br />on the exterior wall. The suction line has a fitting with a screen to filter <br />foreign objects prior to pumping. When needed, trays of waste antifreeze <br />are emptied into the tank using the electric pump and hose piping above. <br /> <br />Pump type(s)/capacities: A small Little Giant (Model 5UXN4) electric <br />impeller pump (115VAC, 60 Hz, 1.6A, 7 ft. of suction lift, 6 gpm) is used to <br />empty portable trays and fill the tank. <br /> <br />Material Storage 66265.192(k)(8): <br />Material and characteristics: The material is waste antifreeze from Truck <br />Division maintenance activities. It is classified as a hazardous waste due <br />to toxicity. The waste antifreeze is classified as a non-RCRA hazardous <br />waste, liquid (ethylene glycol solutions). <br /> <br />Specific Gravity: 1.1 to 1.4 <br /> Operating Capacity: 275-gallons <br />
