The performance standards of Section 4.03 for the various roads at the Eagle mine complex are met by the following: <br />• County roads, maintained by EC, and all other roads aze subject to the BACT requirements of EC's Air Quality <br />Permit. <br />• Roads to be reclaimed are subject to the post-mining land use requirements as set forth in this pemvt. <br />• All roads are designed and maintained to ensure the safety of the public through proper grades, cuts, fills, and so <br />on. <br />In order to determine compliance with the CMLRD performance standards, the engineering company of CTL- <br />Thompson, Inc. was requested to evaluate all access and haulage roads on the EC property. The report issued by <br />CTL-Thompson, Inc. verified that all roads utilized by EC are in compliance with the performance standards. The <br />CTL-Thompson, Inc. report is included in Exhibit 17, Road Certification. <br />As per Map 27, there are a number of haul roads associated with the mine complex. Although the haul roads have <br />been used mainly [o transport development waste and coarse reject from the rotary breaker to [he waste disposal areas, <br />they were designed and maintained to haul road requirements. Figure 56A provides a typical cross-section through <br />haul road A. <br />Haul road A will be utilized to transport coal from the existing coal handling facility to its intersection with County <br />Road 107. Moffat County is allowing EC to use County Road 107 for coal haulage. <br />Haul road A is apre-existing road that was built prior to the enactment of the Surface Mining Control and <br />Reclamation Act of 1977. The road was constructed in accordance with accepted road construction practices, and as <br />such culverts were placed in the various drainages [he roads crossed. Map 27A shows [he road location, and Figure <br />S6A provides a typical cross-section. Peak flow information obtained from Trapper Mine's permit document indicates <br />the peak flow in West Buzzard Gulch is 178 cfs, while the East Buzzard Gulch peak flow will be 13 cfs from <br />Trapper's pond (East Buzzard #1R). Presently, 16-inch CMP pipe is in place in both of these drainages. Also, a 16- <br />inch CMP is in place in an unnamed tributary east of East Buzzard Gulch. <br />EC's calculations indicate that the West Buzzard Gulch culvert should be 60 inches in diameter, while the East <br />Buzzard Gulch culvert should be 36 inches in diameter. The eastern most culvert is more than sufficient to handle the <br />runoff from the small drainage area. This culvert will handle a peak flow up to 13 cfs. Dense vegetation is <br />established at the inlets and outlets of the culvert. Therefore, rock headwalls will not be constructed. <br />Additional work will be done on haul road A prior to using the road. The work will include upgrading the culverts to <br />the required size, as presented above. Once the new culverts are placed, the inlets will be protected by either wing <br />wall or rock headwalls. <br />Haul Road A joins Moffat County Road 207 in the southwest comer of section 28 T6N 91 W as shown on May 27A. <br />Moffat County Road 107 located in section 28 has not been vacated to EC. As stated above, Moffat County will allow <br />EC to haul coal over this road. <br />The existing road located within Trapper's permit area overlies EC's State of Colorado coal ]ease, and as such, EC has <br />the ability to use the surface to the extent needed to mine the coal. Trapper has been contacted and an agreement will <br />be reached with Trapper for use of the road. Once [he haul road is used by EC i[ will be EC's responsibility for <br />maintaining the haul road in compliance with the regulations until such time as it is reclaimed or left as a permanent <br />post mining road. If the road will become part of the post mining road network, a revision will be submitted to [he <br />Division requesting approval for [his use. <br />Haul road A will be surfaced with a durable material, such as crushed red rock or gravel, capable of handling the <br />anticipated vehicle load. Both red rock and gravel have been used successfully at EC's operation. Therefore, either of <br />these materials will provide for a durable surface. It is anticipated that tandem trailer trucks, which can hau148 - <br />Permit Revision 04-34 2.05-17 Revised 7/2/04 <br />
