Three 3. The applicant should define "representative" overburden, "com- posite samples", and how these samples were obtained and analyzed. 4. The applicant needs to provide the lithology logy for all drill holes. 5. The applicant must provide a textural analysis for the carbon- aceous shale, gray shale, and sandstone in the coal zone, and siltstone beneath the lower coal seam. 6. The geologic cross-sections provided do not delineate nature, depth, and thickness of the coal seams to be mined, each over- burden stratum, and the stratum immediately below the lowest coal seam to be mined. T~~is information should be incorporated into the geologic cross-sections. 7. The applicant should provide information on the swell factor of the overburden material. swell factor values and a description of the methodology utilized to determine these values should be provided. 2.04.7 Hydrology Information The applicant has not provided sufficient hydrology has eline information. The applicant should address the following topics, and provide the requested information. 1. The applicant should provide all surface and ground water moni- toring data collected. 2. The applicant should provide a pieziometric contour map of all aquifers down to the first aquifer below the lowest coal seam to be mined, unless the applicant can provide sufficient information (from pump tests and monitoring) that there are none. 3. The applicant should provide a narrative which describes the known uses of the water in the aquifers and water table and lists the current users of all surface crater and the amount utilized by each user. The applicant should address storage rights of ponds below the permit area in Mdnn Draw. 4. The applicant should provide information which addresses recharge, storage, and discharge characteristics of aquifers of the permit and adjacent area in order to determine impact of the operation on the hydrologic balance. 5. The applicant needs to provide elevations for all water monitoring stations. 6. The applicant needs to address how the operations may result in contamination, diminution, or interruption of surface or ground water. If the operation may cause contamination, diminution or interruption of the supply of water to a user with a ZegaZ right to that water, the applicant needs to identify alternative water supplies which could be utilized to replace the existing sources.
