Upper Mine Access Road, Mountsln Coal Company's Waat Elk Cost Mina (Formerly Mount Gunnison No. 1 Mine); Merrick Ref/: 103-337fi Dear Ms. Weh: Per your request, we have reviewed our design files in relation to the design e1 the o-Iplnal access road at the West Elk Coal Mine. This access road is currently dnided into three reaches. These are titled the Stack Tubas Access Rnad, the Middle Mlne Access Road, and the Upper Mine Access Road. The purpose of our review is to tletermine whether these access roads would comply whh the Colorado Division of Minerals and Geology (CDMGI Haul Road Spapfirstion Section 4.03.1131. The site was formerly known as the ARCO Mount Gunnison No. 1 Mine. In 1981, MerrlCk & Company provided the design of much of the original curtace improvements including the main access road. The road was constructed in 1982. ARCO Coal Company provided day to day on-site construction observation. Upon request by ARCD Coal Company, Menlck $ Company visited the she on two or three occasions during construction of the road system to provide engineering consuhation. Project Record Information was recorded by The contractor antl the ARCD Coal Company personnel. This information is shown on the Project Record Drawings, dated Maroh 3, 1983. The access roads are being certified as haul roads leven though they are within the original and current disturbed mine site and not outside this area as speclTied in Rule 4.03.1(1)Id)) as coal or coal refuse may occasionally be hauled on them. These roads now primarily serve as access roads throughout the mine she. The closure of the original access roads Inow the stack tubes and middle mine access roads) wag Caused by the construction of the stack tubes and crusher building. It Is our understanding that The Mountain Coal Company will be using H-20 type trucks or less heavier vehicles to Carry the coal or coal refuse on this road. The number of trips would be less than 20 per day. In this case. the "haul' road term applies primarily because of the nature of IM11MVR~aE1RMpD\WrlT,77 r M F.nyMeedLwni lorgira
