PEPBOYS� . . <br /> 8 February, 2000 <br /> , y <br /> �r <br /> County of San Joaquin <br /> Environmental Health Dept. <br /> P.O. Box 3888 <br /> Stockton, CA 95201-0388 <br /> Attn: Ms. Donna Herin, Director <br /> Re: Request for Exemption from Engineering Certification <br /> Pep Boys #562 at 1401 South Cherokee Lane, Lodi, CA 95240 <br /> Ms. Herin: <br /> It is our understanding that your agency implements the State of California's hazardous waste <br /> management program requirements for generators. As a generator of hazardous waste, our Pep Boys <br /> facility located at 1401 South Cherokee Lane, Lodi, CA 95240 generates waste oil and antifreeze from <br /> the servicing of automobiles. <br /> In accordance with state hazardous waste regulations, Pep Boys #562 manages these wastes as non- <br /> RCRA hazardous wastes. Waste oil is accumulated in one 500 gallon above ground storage tank (AST) <br /> and both waste antifreeze and oily waste water (from shop floor washing) are accumulated in two 280 <br /> gallon ASTs. All three ASTs are equipped with secondary containment and all wastes are shipped <br /> offsite for recycling. <br /> California Code of Regulations Title 22, (22 CCR) section 66265.1920) states that aboveground non- <br /> RCRA tank systems with secondary containment, whose design and installation have been approved by <br /> a local agency or agencies, may, at the discretion of the Certified Unified Program Agency (CUPA), <br /> be exempt from the engineering assessment specified in 22 CCR, 66265.192, provided the following <br /> criteria are met: <br /> • The tank system must have secondary containment capable of containing 100 percent of the <br /> contents of the tank and ancillary piping volume. <br /> • If the tank system is exposed to precipitation, the secondary containment system must have <br /> sufficient capacity, in addition to that required in subsection 0)(1) of this section, to contain run-on <br /> and infiltration from a 25-year, 24-hour rainfall event. <br /> • Tank system seccl'ndary containment shall be provided with a leak detection system that is designed <br /> and operated so that it will detect either the failure of the primary and secondary containment <br /> structure or any release of hazardous waste or accumulated liquid in the secondary containment <br /> system within 24 hours, or at the earliest practicable time if the existing detection technology or <br /> site conditions will not allow detection of a release within 24 hours. <br /> 3111 West Allegheny Avenue•Philadelphia,Pennsylvania 19132•(215)229-9000 <br />
