a confinement boom. The detention time and surface area on the iNet side of the confinement boom allow <br />• the petroleum effluent to be trapped behind the boom, where it may be pumped off and disposed of. Any <br />remaining petroleum effluent is then removed as discharge from the pond proceeds through two concrete, <br />buried oiUwater separators. The clean water is discharged while the retained oil is collected and disposed of. <br />All non~uried tanks will be subject to visual inspection annually. Records of all inspections will be kept on <br />file for at least three years. <br />(e)(2)(iv)All remaining underground storage tanks at Trapper were removed N April 1990. <br />(e)(3)(i) Piping systems at the facility are designed and operated in a mwner [o prevent spills. All underground <br />piping is wrapped for protection against corrosion. If for some reason buried lines are exposed, they will be <br />inspected. if the inspection shows corrosion damage, corrective measures will be taken. All above-ground <br />pipes and valves shall be within We earthen dikes in case there is a pipe failure. These dikes also prevent <br />vehicular damage to above-ground components. <br />(e)(3)(ii)Terminal connections of pipe which are not in service will be capped or valved. <br />(e)(3)(iii)Pipe supports are designed to minimize abrasion and corrosion and allow for contraction and expansion. <br />(e)(3)(iv)All above-ground pipes and valves will be inspected annually.

All above-ground <br />tanks, piping, and valves will be visually inspected once a year. The inspection reports will be kept on fde <br />for a least tlvee years and will include at least three inspections. If problem areas aze found, afollow-up <br />inspection will be made after corrective measures are taken. Inspections will be performed during the third <br />quarter of each year by a member of the engineering staff. <br />(e)(9)(i) Access to the mine site is controlled at all times. In addition, when the mine is not producing, all gates are <br />locked or guarded. <br />(e)(]0)(i) All foremen and shift supervisors will be trained in this plan at least once a year. The training will include <br />spill prevention, spill reporting procedures and the basics of the current SPCC plan. <br />In addition, appropriate personnel will receive training on the control of hazardous waste spills, handling <br />procedures and appropriate emergency response procedures. <br />Any contractor, subwntractor, or temporary personnel whose work could cause a spill or who could prevent <br />a spill will be informed of facility operating procedures and features with which they may become involved. <br />(e)(10)(ii) The shop foreman on duty is the Emergency Coordinator and will be responsible for emergency response to <br />spills, and also for reporting spills according l0 33 CFR - 153-203 and 40 CFR 262.34. <br />~J <br />Revision: .;_,p_` <br />4-lsc APProved:MAY_]~g9 <br />
