Section - 2.05.3 The first segment of the II West Haul Road extends from the switchback on the existing West Valley • Haul Road, across the existing West Valley Coal Refuse Facility, to the crossing of the existing West Valle}' upland diversion and intersection with the II West (Pond E) Light-Use Road. In addition to the uses previously noted for all road segments, this segment of the road will also be used to access the II West Light-Use Road for initial construction and ongoing inspection, maintenance, and final reclamation of Pond E. This section of the road is constructed as a fill road over 4 feet of suitable cover on the top bench of the West Valley Coal Refuse Facility, is approximately 363 feet long, and has an average positive grade of approximately 5.6 percent. The second segment of the II West Haul Road extends from the crossing of the existing West Valley upland diversion and intersection with the II West (Pond E) Light-Use Road to a grade break in the road just east of the first ephemeral drainage between the West Valle}' and II West Coal Refuse Facilities. 'T'his segment of the road is approximately 547 feet long and has an average positive grade of approximately 3.8 percent. The third segment of the II West Haul Road extends from the grade-break east of the first ephemeral drainage between the West Valley and II West Coal Refuse Facilities to the eastern limit of the II West Coal Refuse Facility. This segment of the road is approximately 522 feet long with an average negative grade of 0.5 percent. Drainage control for the II West Haul Road is provided by roadside ditches and cross-culverts. Drainage design details aze illustrated by both the General Facilities Map (Map 2.05-M1, Sheet 5) and the Drainage and Sediment Control Plan Map (Map 2.05-M4, Sheet 5), and design calculations aze provided in Exhibit 2.05-E3, Drainage and Sediment Control Plan. Upper Elk Creek Access Road -The upper Elk Creek access road will run between and connect the upper and lower Elk Creek Mine portal benches. This road will be constructed almost entirely on fill and will be approximately 30 feet wide, providing for two-way traffic. Road fill outslopes will be up to 1.SH:1 V and the road will be constructed to the same specifications as the Etk Creek haul road. Drainage control will be provided by roadside collection ditches as part of the Elk Creek Mine surface facilities drainage control network with flow from the road surface being routed to Pond D. Road outslopes have been designated as SAE's and will be stabilized by hydro-seeding and hydro-mulching the outslope azeas. Lower Elk Creek Access Road -The Lower Elk Creek access road will run between the fast segment of the Elk Creek haul road and the existing coal stockpile on the east side of Sedimentation Pond D. This road will be constructed along the alignmen[ of the existing Elk Creek road and will require minimal road construction/modification. Drainage control will be provided by roadside collection ditches. Use of this road will be limited to general access for the north end of the coal stockpile and Sedimentation Pond D. Bear Creek Canyon Road -The Beaz Creek Canyon road is an improved public access dirt road. Somerset Mining Company previously used this road to access the Beaz Creek ventilation shaft and fan installation and did not improve or modify the road. Since the Bear Canyon facilities have been de-activated and the ventilation site reclaimed, this road is no longer used in conjunction with mining- related activities except to periodically check the condition of reclaimed azeas and for hydrologic monitoring. Current use is limited to occasional public access and use by landowners and grazing leasees for lands to the north. • TR-43 2.05-29a Revised August 2003
