Location. The Mine Entrance Haul Road (MEHRI, which was originally constructed in 1975 and • widened in 1989 and Road A, fall under 4.03.1. These two roads cover 4.3 miles. An additional 4.1 miles oT haulage road (Tie-Across Haul Road, TAHR) was constructed from the Hayden Station Power Plant to Routt Ccunty Road No. 53. As-built plans for the "Tie Across Haul Road" (TAHRI, Mine Entrance Road, and Road A are included in this application. Haul Roads B, C, F, and G have previously been approved and are depicted on Exhibit 12-2. As-built plans of Roads F, G, H and I are depicted on Exhibits 13-18.1A, 13-19.1A to 13-19.4A, 13-20.1 A, and 13-21.1A respectively. Designs for proposed Haul Roads J, K and L are shown 6y Exhibits 13-22.1, 13-23.1, and 13-24.1. The planned haulage roads at the mine site are designed with appropriate ditches, grades, and culverts to control erosion and runoff. Exhibit 13-10 and Figures 13-1 and 13-2, illustrates typical cut and fill sections of the haul roads. All haulage roads will be constructed basically "on-grade" and road location will be partially limited by projected final grading limits for the postmining areas. All truck traffic will be routed to enter the pits at an upper elevation and leave the pits at a lower elevation. Most of the haulage roads will 6e built prior to the time mining commences and they will be reclaimed as the roads are mined out or are no longer needed. Some of the haulage roads will be extended through the spoil and road construction will progress with the mining activity. Final reclamation of these roads will occur at the end of the life of the mine. • Haul roads beyond the limit of mining will be located on ridges or on the most stable available slopes to minimize erosion. No haul road will be located in the channel of an ephemeral stream which has a watershed of at least one square mile, on intermittent or perennial stream unless specifically approved by the Division. All stream crossings will be made using culverts. Haul roads will be located and designed to minimize downstream sedimentation and flooding. Stream Buffer Zones. The stream buffer zone along a portion of Sage Creek (land within 100 feet of a perennial stream or stream with a biological community as defined by Section 4.05.1813) of the CDMG regulations) will be affected by disturbance activities within the TAHR permit area. The design plans for the haul road were developed so that there will be no disturbance to the main channel of Saga Creek. Disturbances within 100 feet of Sage Creek were limited and consisted of activities directly related to the construction of the haul road embankment. u 11 Revised 06/01
