4.1.2.4 Spill Prevention and Control at the New Truck Shop <br />• The most important activity to prevent spills at the New Truck Shop is operator care in the transfer of <br />fluids, using common sense and diligence in making sure connections are secure, drip pans are in <br />place, and containers are positioned to receive fluids properly. <br />Bulk storage of petroleum products is primarily insidethe New Truck Shop building in the Oil Room. <br />The New Truck Shop Oil Room is a secondary containment in itself, with a concrete floor and footings <br />that extend up at least one foot from the floor in order to provide 43,000 gallons of containment <br />capacity. Spills from tanks in the Oil Room, whether from tank rupture, overfilling, or pump /piping <br />leaks, will be contained inside the containment structure. The containment structure is more than <br />adequate to hold 110% of the volume of the largest tank (12,000 gallons; see Table 4 above). <br />Mounted on the wall of the New Truck Shop Oil Room is an electronic display panel that monitors th'e <br />volume of materials in the various tanks. <br />There is athirteen-connection fill manifold located outside the building on the north side of the New <br />Truck Shop. The 13 off-loading connections on this manifold are directly linked to the tanks in th'e <br />New Truck Shop Oil Room. All fill lines are fitted with back-flow check valves located near the <br />outside-terminus of the fill lines. The off-loading area is built on a concrete containment pad that <br />slopes inward to the building and there is a sump beneath the pad that will collect spills. Collected <br />fluids in the sump can be pumped to the used oil storage tank. No overfill warning devices are <br />installed. <br />The majority of the used oil is burned in oil-fired boilers that provide heat to the New Truck Shop. Off- <br />site disposal of used oil occurs on very irregular basis when there is a surplus of used oil. Prior to <br />these trahsfers of used oil, tank reading will be obtained from the storage tank to estimate the volume <br />of used oil remaining in the tank. Any transfers of used oil from the storage tank to a transporter's <br />truck will be continually attended by the transporter to monitor for leaks and/or spillage. A spill of <br />• antifreeze will be managed separately from used oil and will be placed in a container labeled "used <br />antifreeze." <br />4.1.2.5 Spill Countermeasures (Clean-up Procedures) at the New Truck Shop <br />Section 3.2 provides the general spill response procedures for use at the New Truck Shop. The <br />following narrative provides additional detail on spill clean up. <br />Small Spills Outside of Containment Structures <br />Spills from totes, drums, or pails can be contained entirely within the New Truck Shop building and <br />relatively easily removed from the concrete floor. Material spilled within the building will be recovered <br />with a sorbent material (sorbent pads, pillows, oil dry, bentonite or "kitty litter"). Sorbent pads that <br />have been used to remove petroleum products, including fuels, antifreeze, and oils, can be disposed <br />of as a conventional solid waste and can be placed into the commercial solid waste containers <br />(dumpsters) at various locations around the property, provided no solvents or other potentially <br />hazardous wastes have been added. Sorbent materials that have been saturated with oil but are not <br />dripping can be disposed as conventional solid waste. <br />Leaks or spills of petroleum products during transport or during product transfer will create an oil stain <br />on"the ground surface. CC&V's clean-up policy is as follows: If the majority (>50%) of the area <br />consisting of 9 square feet (3 feet by 3 feet) is affected (stained), then the affected area will be <br />removed (i.e., the soil and oil mixture) and placed in the blast hole stemming material pile or as <br />directed by the Environmental Resources Department. <br />• Spill Response Plan September 25, 2006 <br />EMS: AGANA/CCVS:\4010-00055 CC & V 112(d) Permit Application\ERP, SPCC, FMP\SRP_05-06.doc Doc. # E-006 <br />S:\4010-00055 CC & V 112(d) Permit Application\ERP, SPCC, FMP\SRP_05-06.doc Revision 03 <br />Printed Copies are Uncontrolled <br />17 <br />
