wood. <br /> Antifreeze is not categorized as a combustible liquid, although there is a <br /> slight to moderate fire hazard when exposed to high heat or flame (auto- <br /> ignition temperature of engine coolant is 750 °F). The HDLPE tank is <br /> located under a canopy in a hazardous waste storage area with warning <br /> signage. Although antifreeze exhibits a flammability hazard when exposed <br /> to high heat, ignition of ambient temperature ethylene glycol vapors <br /> through electrostatic discharge is improbable; lightning protection <br /> (grounding rod) is not required. <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 /> The tank is bounded by a building on the west and further protected from <br /> vehicular traffic by a series of bollards and attached metal railings on the <br /> north and east sides. <br /> Piping and ancillary equipment (pumps) 66265.192(k)(2)(C&D): <br /> Piping Material of Construction: 3/4-inch, rubber, hydraulic hose <br /> (discharge line) and 3/4-inch textile-braided, rubber hose (suction line); <br /> exact hose specifications are unknown, but the hosing is consistent with <br /> industry standards and shows no signs of swelling or cracking. <br /> Piping Diameter: 3/4-inch hosing, 1/2-inch rigid piping <br /> Pump location(s): The pump is rigidly mounted (bolted) to a shelf which <br /> is bolted on a horizontal support rail between two bollards along the east <br /> side of the Accumulation Area. The suction line on the pump is used to <br /> empty waste antifreeze from portable containers or EMD, AG, and FS <br /> service trucks. The waste antifreeze is conveyed via rigid piping mounted <br /> along the railing to the tank. Near the tank, the rigid piping connects to <br /> flexible hosing which extends into the tank. The elevation/slope of the <br /> piping provides antisiphon protection. <br /> Pump type(s)/capacities: A 1/2-inch, pneumatic-driven, double- <br /> diaphragm pump (ARO Corp.) rated at 13 gpm (max.) is used to empty <br /> portable containers and service trucks. <br /> Material Storage 66265.192(k)(8): <br /> Material and characteristics: The material is waste antifreeze from EMD, <br /> AG, and FS maintenance activities. It is classified as a hazardous waste <br /> due to toxicity. The waste antifreeze is classified as a non-RCRA <br /> hazardous waste, liquid (ethylene glycol solutions). <br /> Specific Gravity: 1.1 to 1.4 <br /> Operating Capacity: 275-gallons <br /> Wood Environment & Infrastructure Solutions, Inc. 275 Gal.
