Oakridge Energy, Inc., will endeavor to practice every safety precaution with respect to <br />the storage, handling, and use of explosives. The State, M.S.H.A. and other federal <br />regulations will be complied with. <br />2.05.3(71 Coal Handling Structures <br />The structures associated with coal handling have been identified and discussed <br />previously in this permit. These structures include two raw coal stockpiles and an in-pit <br />staging area with crusher/screener equipment. Raw coat which requires ash removal or <br />other cleaning will be screened, crushed and sepazated in the pit. Coal not requiring ash <br />removal will be trucked directly to the staging area. The staging area will be used for <br />surge capacity and blending for the customer. The coal will be trucked from the pit area <br />to the staging area where it will be transported on highway trucks to markets. <br />2.05.3(8) Coal Processine Waste <br />Any coal processing waste will be kept within the confines of the pit or returned to the <br />pit. No refuse or coal processing waste will be impounded and no coal refuse or reject <br />will accumulate outside of the pit. The test for coal reject were performed by Core Labs, <br />Inc. in Denver, Colorado (Appendix 4-3). Quality analysis of typical coal reject to be <br />returned to the pit has been included in Table 4-1. <br />The processing waste analysis indicates that sulfur may be present in vazious forms but in <br />low quantities, i.e. two to three percent (2 to 3%). This low quantity is not expected to be <br />acid forming because it is not acid forming in the coal seams. Note, the analysis of the <br />groundwater samples in Appendix 4-3A. <br />No slurry ponds or wash slurries aze proposed as a part of the mining in this plan. No <br />coal fines aze expected to be generated as a part of the mining activity. The coal fines, as <br />they exist in the coal seams, aze neither acid nor toxic forming. If pit dewatering is <br />necessary, the water will be pumped to Pond No. 1 and discharged in compliance with the <br />NPDES Permit. <br />The sulfur content of the coals and their associated over and underlying strata, range <br />between one and three percent. Abandoned coal mine records for the Durango, Colorado <br />area document no problems with acid mine waters and burned spoil piles. Both of these <br />facts indicate that the coal processing wastes, which will be generated by the Carbon <br />Junction Mine, have a limited potential to be acid-forming and have no reasonable <br />probability of being combustible when placed in the overburden. <br />Settling Ponds <br />No coal settling ponds are planned for the subject operations. <br />TR08, TRI1(v1.0) 3-22 Revised 9/97, 08/02 <br />
