• Wastes generated at Trapper Mine are placed and stored in a controlled manner in the mine facilities <br />complex. Surface runoff from waste storage drains into the industrial waste pond, preventing degrada- <br />tion of surface and ground waters. Final reclamation of these areas is discussed in Section 4.2. The <br />facilities discussed in this section are shown on the Map M13 series and in Figure a.3.-1. None of these <br />facilities are scheduled for removal urnil the coal reserves are exhausted. The removal will be in <br />accordance with the procedures set forth in Section 3.1.7. <br />Impoundment H: <br />Impoundmern H was constructed in mid 1975. This dam was constructed similar to the dam for the <br />industrial waste pond. The impoundmern is currency in good condition and inspected regulary. This <br />pond cornrols runoff from the shop and industrial areas. <br />This pond is dewatered via a self-dewatering device. The facility is similar in design to other small sedi- <br />ment control facilities located at Trapper. (Table 4.8-88, Append'a Q and U) ARernativey, the water from <br />the pond may be used to suppress dust from haul roads. A pump is set-up at the impoundment to fill <br />the road watering equipment. <br />Petroleum Waste Product Bulk Storage Tanks: <br />• In April, 1990, Trapper Mine removed all remaining underground tanks (UST) utilized for bulk storage of <br />petroleum waste products. All waste oil is now collected in a 20,000-gallon surtace tank near the lube <br />building. See Figure 4.3-1 on page 4-15. <br />4-17 <br />I <br />i ~' ;3wisiord AF o 'D <br />~~ DATC J <br />
