3. The proposed upper waste pile includes an access road to be used to <br /> transport waste to the site. The road is planned to be 2,500 feet long, a full <br /> cut-section, gravel surfaced road with grades up to 10 percent. Because of <br /> inaccessibility, due to weather, to the proposed road alignment at the time <br /> of the upper waste pile revision, a geotechnical investigation of the road <br /> corridor has not been completed. This investigation would include a <br /> reconnaissance geologic map with emphasis on slope instabilities and <br /> drainage characteristics. Based on this map, a preliminary access road <br /> cut-slope stabilization and drainage design will be developed. Once <br /> approved by the Division, initial construction will be as a pioneer road with <br /> minimal excavation. This investigation and final design will be completed <br /> as the road is excavated. The upper refuse pile is not proposed for this <br /> permit term; therefore, construction of the road is not proposed. More <br /> information is included as Exhibit 50 in the permit document. <br /> C. Light Use Roads <br /> 1. The West Elk Mine has several light-use roads at the site. They are around <br /> the southern and eastern perimeter of MB-2R and around the base of lower <br /> refuse pile, above the facilities area and on Jumbo Mountain to access <br /> monitoring sites and the water tank, and the Lone Pine Gulch fan road. <br /> The designs, except for some preexisting roads, are in compliance with <br /> Rules 2.05.3 and 4.03.3. Three new light use roads have been proposed for <br /> construction with Permit Revision No. 7. These are shown on Map 53B <br /> and include the following: <br /> Road Name Road Location <br /> Light use Maintenance Road Between Sylvester Gulch haul/access road to <br /> Landing #2 <br /> Water Tank Light Use Access Road Between Existing mine water tank and Light <br /> Use Maintenance Road <br /> Electric Borehole Light Use Road Between Sylvester Gulch Ventilation Facilities <br /> and Electric Borehole <br /> II. Support Facilities - Rule 4.04 <br /> A. Construction of support facilities did not result in any damage to any protected <br /> structures. Therefore, the Division proposes to approve those activities <br /> (4.04(6)). <br /> III. Hydrologic Balance - Rule 4.05 <br /> A. Water Quality Standards and Effluent Limitations <br /> 1. There are five sediment ponds and one freshwater pond at the West Elk <br /> Mine that treat drainage from the disturbed area. These ponds function as <br /> designed to ensure that applicable water quality standards and effluent <br /> standards are met per the requirements of CDPS Permit No. CO-0038776. <br /> 23 <br />
