Some of the used oil may be burned in oil -fired furnaces that provide heat to the Ironclad Shop/Warehouse. Off-site disposal of used oil occurs on a very irregular basis when there is a surplus of used oil. Prior to these transfers of used oil, the storage tank will be "stick- measured" to estimate the volume of used oil remaining in the tank. Any transfers of used oil from the storage tank to a transporter's truck will be attended by the transporter to monitor for leaks and /or spillage. Old Truck Shop Transfers of petroleum products and antifreeze from bulk tankers at the Truck Shop will occur on the North side of the building on a 14 -foot concrete containment pad sloped towards a sump that can be pumped to the used oil storage tank. The fill lines are fitted with back -flow check valves located near the outside - terminus of the fill lines. A spill of antifreeze will be managed separately from used oil and will be placed in a container labeled "used antifreeze." The majority of the used oil generated by oil changes in the Ironclad Facility is burned in oil -fired boilers that provide heat to the Truck Shop. Off -site disposal of used oil occurs on very irregular basis when there is a surplus of used oil. Prior to these transfers of used oil, the storage tank will be "stick - measured" to estimate the volume of used oil remaining in the tank. Any transfers of used oil from the storage tank to a transporter's truck will be attended by the transporter to monitor for leaks and /or spillage. 4.1.1.5 Spill Countermeasures (Clean -up Procedures) at the Ironclad Facility Section 3.2 provides the general spill response procedures for use at the ironclad Facility. The following narrative provides additional detail on spill clean up. Small Spills Outside of Containment Structures Spills from drums or pails can be contained entirely within the Ironclad Facility building and relatively easily removed from the concrete floor. Material spilled within the building will be recovered with a sorbent material (sorbent pads, pillows, oil dry, bentonite or "kitty litter "). Sorbent pads that have been used to remove petroleum products, including fuels, antifreeze, and oils, can be disposed of as a conventional solid waste and can be placed into the commercial solid waste containers (dumpsters) at various locations around the property, provided no solvents or other potentially hazardous wastes have been added. Sorbent materials that have been saturated with oil but are not dripping can be disposed as conventional solid waste. Leaks or spills of petroleum products during transport or during product transfer will create an oil stain on the ground surface. CC &V's clean -up policy is as follows: If the majority ( >50 %) of the area consisting of 9 square feet (3 feet by 3 feet) is affected (stained), then the affected area will be removed (i.e., the soil and oil mixture) and placed in the blast hole stemming material pile or as directed by the Environmental Resources Department. Large Spills Outside of Containment Structures Available earth- moving equipment will be used to excavate a trench and sump system to retain the spill in the immediate vicinity of the spill. Fluids should be recovered into barrels or tanks quickly to minimize seepage. Straw bales may be used to absorb the remaining fluid. Sorbent soils or commercial sorbents may also be used to absorb the fluid.
