J llestern Slope Carbon Preliminary Adequacy Review P1arch 26,~ 1981 2.04.3 Site Description and Land Use Information It is not clear from the application whether the premising use of the land surface disturbed by mining activities r+as livestock grazing and wildlife habitat, or solely wildlife habitat. if ~:ISC is requesting a change in post mine land use, the requirements of 4.16 a+ill have to be met. 2.04.5 General Description of Hydrology and Geology The surficial feology Map (7_.04.5-B) should be revised to include bedrock infor- mation such as strike and din, faults and formation members within the Mesa Verde: 2.04.6 Geology Description 1. Geologic cross sections of the permit area are required by 2.04.6(2)(ii) to illustrate the depth and thickness and the strike and dip of the coal seams to be mined, and the major strata of the overburden down to and including the stratum immediately belor+ the lor•+est coal seam to be mined. At least two relatively perpendicular cross sections rou!lhly bisecting the permit areas should be prepared. 2. Chemical analyses of the coal seams to be mined are required by 2.04.6(2)(a) ' (iii)(C). These analyses are provided~`•~or the "E" and "D" seams, but an analysis of the "wild" seam was not included. Since the seam is going to be mined, this material must be included. ~ 3. In the chemical and physical analyses of roof and floor material, the applicant should specify the particular drill holes from v+hich each of the samples were taken. Chemical analyses should he provided for interburden stratum to be affected by proposed rock tunnels to the lower seams. 2.04.7(1) Ground !Dater Information 1. The applicant has not provided a description of knov+n uses of !eater in the alluvial aquifer or the Rollins Sandstone in the general area as required by 2. The ground water section (pages 2.04-21 to 2.04-26) primarily discusses the occurance of ground water in the "E" seam and the associated roof and floor materials. The ground v+ater discussion must include information on all aquifers down to and includinn the first aquifer below the lowest coal seam too by mined. 3. Alluvial ground v+ater quality is incomplete, no toxic heavy metals were analyzed, Chemical analyses were conducted on only one day, and not on a quarterly basis (Appendix XIV-4). Therefore, seasonal fluctuations of water quantity and quality cannot be assessed. 4. The ground water samples obtained in the mine were not analyzed for all parameters required by the Division. Plo analyses of toxic heavy metals are in- cluded. Additional analyses of r•+ater seeping into the mine from the roof and floor should be run to characterize the ground water impacted by mining. The list of water quality parameters rer~uired for baseline monitoring is attached as Appendix A. Parameters marked X are required,
