5.2.1.2 Above Ground Gasoline Storage Tank <br />• Chemical: Unleaded gasoline. <br />Description: Unleaded gasoline stored in above ground 14,500 gallon tank. <br />Location: Approximately 700 feet NW of No. 6 Crusher. <br />Spill Potential: Moderate at fill point. <br />Potential Spill Volume: 14,500 gallons if entire tank spills. <br />Prevention and Control: During fill operations, Gaze must be given to replacement of the hose <br />inside containment to prevent accidentally leaving the hose in the fill position. Similarly, <br />running over hoses is a likely source of spillage. A concrete containment berm surrounds the <br />tank; it measures 30.5 ft x 61 ft x 2 ft for a total containment volume of 28,000 gallons. <br />Countermeasures: Small amounts (<20 gallons) of spilled gasoline inside containment can be <br />allowed to evaporate. Larger spills inside the berm should be cleaned up with sorbent booms and <br />pillows. Spills outside of containment, if greater than 20 gallons, should be diked and contained <br />with sorbent booms. Gasoline stained soils should be excavated and disposed of in Climax' <br />landfill, with the approval of the Environmental Department. <br />• Nearest Clean-up Equipment: Spill kits aze located in the Moly Wazehouse. <br />Visual Inspections and Integrity Testing: The above ground gasoline tank is checked daily <br />during mine and mill operations. During shutdown periods it is checked weekly. Integrity testing <br />and a professional "in-service inspection" for the 14,500 gal Gasoline Tank was performed in <br />July 18, 2000 by Conam Inspection Inc. Integrity testing results are included in Appendix 3. <br />Reporting: All gasoline spills greater than 20 gallons should be documented on the "Spill <br />Incident Report" form immediately (Appendix 1), and given to the Environmental Department. <br />Conformance with Applicable Requirements: The overall housekeeping effort was observed <br />to be good during site inspections of July 24, 2003. The steel tank appeazs to be in good <br />condition. Containment is more than adequate to hold the volume of the largest tank plus an <br />allowance for precipitation. Applicable state guidelines aze assumed to be the same as the <br />Federal Regulations at 40 CFR Part 112, and therefore, under §112.7(j) the 14,500 gal Gasoline <br />Storage Tank Area is currently in conformance with applicable requirements with respect to <br />secondary containment. <br />28 <br />
