<br />TR9PPER DINING INC. <br /> <br />June 27, 1990 <br />CERTIFIED #P568141671 <br />Mr. David Berry <br />Colorado Mined Land Reclamation Division <br />215 Centennial Bldg. <br />1313 Sherman St. <br />Denver, CO 80203 <br />Dear David: <br />Subject: Minor Revision 102. Haulroad Expansion Near Main Shop and Culvert Replacement. <br />Haulroad Expansion <br />Trapper Mining Inc. proposes to construct a 450-foot haul truck turn out lane adjacent to our main haulroad <br />to the Craig Station coal loadout. The area is located immediately east of the shop complex whore vehicles <br />turn out onto the main haulroad from the haul truck ready line. On several occasions in the past, vehicles <br />(haultrucks and light duty trucks) have nearly collided at his location. The addition of the proposed truck <br />lane would eliminate future safety problems at this intersection. This construction would enhance and <br />refine a short segment of a previously approved haulroad. Construction would be in accordance with our <br />permit section 3.7.2 and within our approved haulroad width criteria (100 ft) as specified on permit page 3- <br />163. <br />Approximately .5 acres of cropland would be disturbed with the topsail (1,008 bcy's) being appropriately <br />stockpiled in the field immediately east of the stripped area. <br />Appropriate fill material would be acquired from a previous topsoil salvaged road cut area located at the <br />intersection of the main haulroad to Derringer pit and the Colt pit/Ash pit haul roads. Overburden removal <br />from this area would provide greater truck visibility and added safety assurance at this intersection as well. <br />David, we hope to complete this work during the mine shutdown scheduled for June 25-July 7, 1990. <br />Following construction, the road will be certified by a professional engineer and the roads map M9 (sheet 1 <br />of 4) will be updated to address the change. <br />Culver[ Installation <br />During your May inspection of Trapper Mine it was noted that the sizing of two existing culverts (both 18" in <br />size), one in West Buzzard and one in East Buzzard, was inadequate for the peak flaws associated with these <br />drainages. The culvert in West Buzzard drainage is located on an access road (Empire approved haulroad) <br />immediately upstream of sediment pond #I. In East Buzzard drainage, the culvert is located under the <br />access road between sedimem ponds 1 and 2. As discussed during your inspection, these existing culverts <br />pre-date Trapper's mining activity. However, to ensure compliance with all appropriate state and federal <br />rules and regulations, these culverts will be replaced with appropriately sized culverts to carry peak flows. <br />Trapper proposes to install a 36" culvert in East Buzzard Drainage and a 60" culvert in West Buzzard <br />Drainage. Attached is updated permit table 4.8.1 "Haul Road Culvert Sizing" and Roads map (sheet 2 of 4). <br />The culverts to be installed will be labeled BC-6 (East Buzzard) and BC-7 (Wes[ Buzzard). The Roads map <br />M9 shows the location of the proposed 60" and 36" culverts in West and East Buzzard drainages, <br />respectively. <br />P.0. Box 187 Craig, Colorado 81626 (303) 824-4401 <br />
