C. Light Use Roads <br /> 1. The West Elk Mine has several light-use roads at the site. They are <br /> around the southern and eastern perimeter of MB-21Z and around the base <br /> of lower refuse pile, above the facilities area and on Jumbo Mountain to <br /> access monitoring sites and the water tank, and the Lone Pine Gulch fan <br /> road. The designs, except for some preexisting roads, are in compliance <br /> with Rules 2.05.3 and 4.03.3. <br /> It. 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 /> 2. The Division proposes to grant small area exemptions from the use of <br /> sediment ponds, due to the limited size of the area, the fact that ponds and <br /> treatment facilities are not necessary for the drainage to meet the effluent <br /> limitations of Rule 4.05.2 and applicable State and Federal water quality <br /> standards for receiving streams, and due to the fact that no mixing of <br /> surface drainage with a discharge from underground workings will occur. <br /> The small areas to be exempted are located at the Sylvester Gulch fan site, <br /> the lay-down area between FW-1 and MB-1, an area located downstream <br /> from the MB-5 inlet, the 1.2 million gallon water tank, the Lone Pine <br /> substation, and the Lone Pine ventilation fan and associated facilities <br /> (4.05.2(3)(b)(i)). <br /> B. Diversions and Conveyance of Overland Flow <br /> 1. Sediment control ditches have been designed and constructed in compliance <br /> with Rule 4.05.3. Locations are shown on Map 54, and designs can be <br /> found in Exhibit 66. A summary of the designs can be found on Table 44 <br /> in Exhibit 66 of the permit document (4.05.3(2)). <br /> C. Stream Channel Diversions <br /> 1. The West Elk Mine does not propose any stream channel diversions; <br /> therefore, this section is not applicable. <br /> 22 <br />
