B. Storm Water Collection and Disposal System 1. Storm water is collected at catch basins and drains by gravity (aided by two intermediate lift stations) to the Storm Vater Ponds Lift Station at the west end of the site. 2. Storm water is pumped to one of the ponds until full, then tested by City of Stockton personnel, and if approved, it is pumped to the City sewer system by a metered dual pump station. While one pond is being pumped down, incoming storm water is pumped to the other pond. 3. If any pump stations fail, storm water will pond on the site and be contained by the earth dikes. Portable pumps are used to pump storm water to the ponds until pumps sta- tions are restored to operation.* IV. Off-site Spills A. Potential of Off-site Spills 1. Potential for major off-site chemical spills is low due to containment facilities previously described. The perimeter dike system should contain any spills that go beyond local containment facilities. 2. Although it is fairly unlikely, a minor off-site spill could occur if a flowing spill went past a damaged section of earth dike or if a tank truck overturned near the site perimeter. Since these are unlikely, no additional containment pre- cautions need be taken beyond those listed above. In the event a spill of this type did occur, cleanup measures as listed below would be undertaken to minimize further spread of hazardous materials. B. SPCC Plan 1. Off-site spills, if any, are expected to be small. Cleanup should consist of absorption, shoveling into barrels and transporting to a Class 1 site. Any flowing spills should be contained by constructing earth dikes with loaders or by hand labor. Contaminants should be removed by absorption or pumping with portable pumps. All contaminated soil shall also be transported to a Class 1 disposal site. X-31 * This procedure was employed successfully several times during the winter of 1978-1979 when the pumping system was being constructed.
