1 <br />' materials aze available on site to handle spills of this size that occur <br /> outside of the steel containment vessel wall. <br /> b. Maximum tank truck single compartment capacity failure. Maximum <br />spillage is 3,500 gallons, which would be discharged through a 3-inch <br /> valve opening. The average flow rate would be 175 gal/min, and the <br /> tank would empty in about 20 minutes. Since deliveries aze made only <br />' during business hours and there aze always personnel in the pit azea <br /> within sight of the fuel storage area, it is likely that the spillage would <br /> be noticed very quickly. Sufficient personnel, equipment, and <br /> absorbent materials are available on site to quickly absorb this spill. <br /> This response procedure is included in personnel training. <br />' Dispensing pumps - <br /> a. Overfill of fleet vehicles. Maximum estimated spillage 5 gallons. <br />' Pumps aze equipped with automatic shutoff nozzles. <br />' b. Rupture of dispensing hose. Maximum spillage estimated at 5 gallons. <br /> The electrical power to the pumps can be shut off at the pumps. <br />' c. Dislocation of the pump by vandalism or accident. Maximum <br /> estimated spillage 100 gallons. The pump stations are equipped with <br /> breakaway valves that would shut off the flow from the supply pipe <br />' automatically. If these valves were to fail, there are valves at the base <br /> of the tanks that can be used to shut off flow to pump supply lines. <br />' d. Afrer hours major vandalism. The pumps are shut off electrically from <br /> a locked switch box. Destruction of property would be the only cause <br /> of a spill. Maximum estimated spill is 10,000 gallons. The pump is <br /> located in the steel containment vessel. <br /> For a spill caused by a vehicle overfill or rupture of dispensing hose related to the <br />' dispensing pumps sufficient bloCing materials are available to quickly contain or absorb <br /> any spill. If the pump were dislocated by vandalism or accident or an after-hotus major <br /> vandalism incident were to occtu, the steel contaitment vessel around the storage tank <br />' would contain the spill. The steel containment vessel has a capacity of 11,220 gallons <br /> and it could contain a rupture of the fuel tank, 10,000 gallons. <br />' 2.1c Used Oil Tank <br />' Used oil from mining equipment is collected and stored in containers, which aze enclosed <br />in a steel containment vessel. The storage and containment of the used oil for the pit is <br /> discussed in section 2.26 below. As with the fuel storage facilities, the procedtues <br />' contained in this plan will be implemented prior to placing the used oil facilities in <br />vi <br />in a new <br />fter movin <br />them from th <br />se <br />it loc <br />ti <br />de <br />leted <br />it <br /> p <br />g <br />r <br />ce <br />a <br />on a <br />p <br />p <br />. <br />e <br /> <br />11 <br />1 <br />
