4.0 DESIGN AND OPERATING INFORMATION (40 CFR 112.7) 4.1 Reportable Spill There have been no reportable spill events at the facility since it has been functional as of July 2013. 4.2 Potential Spill (40 CFR 112.7 (b)) Total bulk petroleum storage capacity potential at the CHCF-Stockton is 42,682 gallons; of which 42,682 gallons is comprised of diesel fuel. There is approximately 220 gallons of various petroleum fluids (lubricating oils, hydraulic oils, etc.) stored in containers less than 55 gallons. The Generator Yard, Vehicle Sallyport and Water Plant areas are the only areas with a reasonable potential for equipment failure (such as tank overflow, tank rupture, fuel line rapture, or leakage) which could result in a spill. These areas are described in Section 3.2. The predicted direction, rate of flow, and quantity of product which could be discharged from each area is presented in Table 4-1.

A spill event could be caused by the rupture or leaking of one of the ASTs or fuel lines to the backup generators (Figure 3). 8411599 Page 6
