DRAINAGE OF CONTAINMENT AREAS (40 CFR 112.8(c)(3) <br /> Drainage from the concrete berm surrounding tanks AST-1 through AST-4 is a pipe located in the <br /> northeast corner of the containment berm wall. Drainage from the pipe is restricted by a gate valve to <br /> keep water in the bermed area. The valve must be kept in the closed position, except when draining the <br /> secondary containment berm. The content of the secondary containment berm must be inspected by <br /> Facility personnel prior to draining to ensure that only oil-free water is allowed to enter the storm water <br /> drainage system. After the inspection verifies that only oil-free water will be released, the bypass valve <br /> will be opened, and the accumulated water will be released under direct and continuous supervision. <br /> Drainage from the containment area flows into a storm drain inlet located in the parking area to the north <br /> of the containment area. <br /> Drainage events are recorded in the log included in Attachment B to this SPCC Plan and must be <br /> kept with the Plan for at least 3 years. <br /> COMPLETELY BURIED TANKS (40 CFR 112.8(c)(4)) <br /> There are two USTs at the Facility. Two of the USTs are located near the convenience store building: <br /> a 10,000-gallon regular gasoline UST and a 20,000-gallon UST split into three compartments. The <br /> compartments include a 12,000-gallon regular gasoline compartment, a 4,000-gallon diesel <br /> compartment and a 4,000-gallon premium gasoline compartment. The remaining UST is a 6,000- <br /> gallon tank containing DEF that is located to the west of the diesel dispenser canopy. The USTs are <br /> exempt from the requirements of the SPCC regulations as they are properly permitted with the local <br /> permitting agency. <br /> PARTIALLY BURIED TANKS (40 CFR 112.8(c)(5)) <br /> There are no partially buried tanks at the facility as defined in 40 CFR 112.2. <br /> Joe's Travel Plaza <br /> 15600 Harlan Road,Lathrop,CA <br /> Page 18 <br />
