PROCEEDING TOWARD THE PORTAL BENCH, SHALL READ: "ROAD SLOPES SUBJECT TO ROCKFALL AND SLOPE FAILURE -PROCEED WITH CARE." Grand Valley Coal Company's Permit Revision Application No. 1 proposed the construction of two new access haul roads. The first will allow the transportation of coal and processing wastes from the McClane Canyon workings, along East Salt Creek, to the new central processing facility located within the Munger Canyon Mine's permit area. The second roadway is proposed by the applicant to allow the haulage of coal processing waste from the new central processing facility, southwazd along East Salt Creek, to a new proposed refuse disposal area. The applicant also proposed the construction of roughly two miles of overland conveyor for the purpose of transporting product coal from the Munger Canyon Mine Portal to the new central processing facility. This conveyor roughly parallels that of the approved access haul road to the Munger Canyon Mine Portal Bench. As was the case of the approved Munger Canyon Mine portal road, each of these three transportation routes requires the creation of some relatively large cuts and fill embankments. As was also the case in an earlier review situation, the proposed fills conform to the maximum allowable grade limitation contained within the regulations and are, therefore, acceptable. However, as was also the case in that earlier application, several of the cuts exceed normal limitations or are so extensive that they require specific stability analysis to determine their stability. In order to satisfy the requirements of the regulations, and in response to eazlier Division adequacy comments, the applicant specifically discussed and analyzed the stability of the following proposed road and conveyor cuts: Surface Facility Survey Station Operational Safety Factor Cut Height Road from Central Processing to 28 + 50' to 65 feet 1.69 Refuse Disposal Area 31 + 70' Same 40 + 40' to 60 feet 1.72 45 + 50' Same 45 + 50' to 4~ feet 1.61 48 + 40' N1cClane Canyon Road 20 + 50' to 80 feet 1.67 23 +,j• 22
