Hazardous Waste Tank Assessment—Used Coolant Tank September-17,2021 American Tire&Truck Repair Project No.1241 French Camp,CA Page 2 coolant from the pan is pumped to the AST using a double diaphragm pump. The tank is emptied through an oval shaped port that is approximately 10" in the long dimension, located on the top left corner of the tank. Used coolant is removed by the licensed has mat hauler using a stinger attached to a flexible hose. • Description of any external and internal pumps {22 CCR §66265.192(k)(2)(d)} External double diaphragm pneumatic pump. • Sketch or drawing of tank including dimensions 122 CCR §66265.192(k)(2)(e)} See design drawing 151 D in Attachment A and photographs of tank system(Attachment B) • Documented age of the tank system, if available {22 CCR §66265.192(k)(3)1 The exact date of manufacture is unknown. CES contacted Valley Pacific Petroleum Inc. (VPPI) and provided photos and the serial number on a tag affixed to the tank. They were unable to locate design drawings or specifications for the tank. They noted that VPPI purchased Woolsey Oil approximately 15 years ago. We estimate the age of the tank to be at least 20 years old. • Description and evaluation of any leak detection equipment 122 CCR §66265.192(k)(4) There is no interstitial monitoring port on the tank. The outside of the tank is visually monitored for leaks and recorded daily. • Description and evaluation of any corrosion protection, equipment, devices, or material {22 CCR §66265.192(k)(5)1: The outside of the AST is in fair condition and coated with blue paint to prevent oxidation of the steel tank. The paint coating is in fair condition. The tank is located inside a metal shed and is not in direct contact with soil or precipitation. The tank is adequately protected from corrosion. The primary tank and secondary tanks are constructed of steel. It is not possible to evaluate corrosion of the primary tank since it is enclosed within the secondary tank, thus no evaluation could be made with respect to corrosion of the primary tank. • Description and evaluation of spill prevention and overfill equipment 122 CCR §66265.192(k)(6)1 The tank is not equipped with an overfill detection device. However, the volume of the tank is visually monitored and the licensed haz mat hauler empties the tank on a monthly basis or when the tank exceeds 3/4 of its total capacity. ,A spill kit with adequate spill response equipment is in the metal shed. • Description and evaluation of secondary containment for the tank system and ancillary equipment meeting 22 CCR §66265.1920) {22 CCR §66265.192(k)(7)1 The steel secondary tank provides at least 110% of the volume of the primary tank. • Hazardous characteristics of the waste(s) that have or will be handled 122 CCR §66265.192(k)(8)1 Used coolant is classified as non-RCRA, California-regulated hazardous waste. The used coolant is generated onsite during the servicing of semi-trucks. It is not a flammable or combustible liquid,thus used coolant is exempt from ignitable characteristic of a hazardous waste. Coolant typically contains additives that inhibit rust and corrosion; thus, it is
