Risk Identification and Assessment <br />• Each facility component or system of the mine has been examined <br />for its potential for causing a release of significant amounts of <br />toxic or hazardous pollutants to waters of the United States due <br />to equipment failure, improper operation, natural phenomena, such <br />as rain or snowfall, etc. <br />The only area that was identified as a potential risk to the <br />environment in the event of an accidental release to waters of the <br />United States is the fuel and oil storage tanks (See attached Plan <br />of Operations Map). The combination of measures that have been <br />developed to meet the objective of preventing or minimizing the <br />potential for release of toxic and hazardous pollutants in <br />significant amounts are explained below. <br />Fuel and 011 Storage <br />There are three diesel fuel storage tanks located at the loadout <br />(See Material Inventory). These kanks will drain into an <br />impoundment area sized to contain a spill, if the tanks were to <br />rupture, plus precipitation. All oil stored at the loadout is <br />supplied by a vendor and arrives in sealed drums. These drums are <br />stored in the impounded area with the fuel storage tanks to <br />provide emergency spill containment. Up to 20 drums and barrels <br />are stored at the loadout at any time. A 200 gallon tank is used <br />• for temporary collection and storage of waste oil. Similar to the <br />fuel tanks, this tank drains to the impoundment area. <br />Under the guidance of the Committee, a Waste Oil Management <br />Program has been instituted. This program entails capturing all <br />used oil and temporarily storing it in either closed drums or a <br />200 gallon waste oil storage tank at the loadout site. <br />Periodically, full waste oil storage containers and any <br />accumulation in the storage tank area collected by a contractor <br />and removed for recycling or disposal. <br />Material Inventory <br />Following is information on the diesel fuel storage tanks and <br />prediction and control of potential spills from these tanks. <br /> <br />
