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 RAG Empire property. The report <br />issued by CTL-Thompson, Inc. verified that all roads utilized by RAG Empire are in compliance with the <br />performance standards. The 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 to transport development waste and coarse reject from the rotary breaker to the 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 RAG Empire to use County Road 107 for coal haulage. <br />Haul road A is a pre-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 the roads crossed. Map 27A shows the road location, and Figure <br />56A 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 />RAG Empire's calculations indicate that the West Buzzard Gulch culvert should be 60 inches in diameter, while the <br />East Buzzard Gulch culvert should be 36 inches in diameter. The eastern most culvert is more than sufficient to <br />handle the 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 />0 <br /> <br />Permit Renewal RN08-05 2.05-17 01/15/09
