University of the Pacific Spill Prevention, Control, and Countermeasure (SPCC) Plan Stockton, California Aboveground Fuel Storage Tanks 3.5 Containment and Diversionary Structures (40 CFR 112.7(c)) Standby Diesel Generators The methods of secondary containment at the Physical Plant include a combination of structures (e.g., built-in secondary containment in the base of the generator unit) and land- based spill response (e.g., spill kits, drain covers, sorbents) to prevent diesel fuel oil from reaching nearby storm drains and navigable waters. Physical Plant - #3 AST Convault The methods of secondary containment at the Physical Plant include a combination of structures (e.g., built-in secondary containment) and land-based spill response (e.g., spill kits, drain covers, sorbents) to prevent diesel fuel oil from reaching navigable waters. For the 2,000-gallon Convault (refer to Section 4.2.2 of this Plan): Double-wall tank construction. The 2,000-gallon Convault AST has an internal secondary containment system. Overfill: The tanks is provided with two or more of the following methods to protect them against overfill: a) direct reading level gauge at the tank which is visible from fill pipe location; b) valve located within fill-pipe access to close automatically at a specified fill level; c) audible high level alarm activated by a float switch at a specified fill level. The tank system includes a five gallon spill containment surrounding the AST fill pipe. The spill container is equipped with a normally closed hand operated valve that can be actuated to drain the spilled fuel liquids into the steel tank. Storm Drain Covers: Storm drain covers are available for placement over the nearest storm drains in event of an uncontrolled fuel discharge during filling operations. In vehicle fueling operations where a discharge could occur: Sorbent material: Spill cleanup kits that include absorbent material, booms, and other portable barriers are located inside the Physical Plant building approximately 75 feet distant from the AST, as shown on the Facility Diagram in Appendix A. The spill kits are located within close proximity of the fuel product storage and handling areas for rapid deployment should a accidental spill occur. The inventory is checked monthly to ensure that used material is replenished. -16- Version 1.0, 11/28/2016
