52,04 APPLICATION FOR PERMIT FOR SIIRFACE OR DNDERGROUND MINING ACTIVITIES -- MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES. 2.04.6 Geology Description, (2) (a) (Cont'd.) Per the Division's recommendation, composite core sam- ples were obtained from RS-3 throughout the strati- graphy which would tie affected by the rock slope en- tries' development. Three strata exhibiting like col- or, lithology and mineralogy were sampled -- gray sand- stone, coaly shale, and brown sandstone. Approximately eight to ten, one-pound samples were obtained from each of the strata, and combined and submitted for labora- tory analysis The results of the analyses are in the Waste Disposal Appendix, Volume 6A. These composites typify the geochemical characteristics of the non-coal stratigraphy which would comprise the constructed de- velopment rock fills. CWI would monitor stratigraphy as the mining of the rock slope entries progresses and sample those components which do not appear to have been represented in the core composite sampling pro- gram, handling the materials accordingly. (i) The depth of the "D" coal seam is depicted on . Map 2-7. The thickness and nature of the "D" coal seam is shown on Maps 10-4 through 10-6, and Maps 10-7 through 1010 (confidential maps). Refer to sheets 2 and 3 of the Orchard Valley West Portals designs in Volume 6B and lithologic logs from the West Portal explora- tion in Volume 10 (confidential) for addition- al information. (ii) Refer to Maps 2-2, 10-1, 10-2, and 10-3, and 10-7 through 10-10 (confidential maps). Refer to sheets 2 and 3 of the Orchard Valley West Portals designs in Volume 6B and lithologic logs from the West Portal exploration in Vol- ume 10 (confidential) for additional informa- tion, (iii) (A) Refer to maps 2-1 and 2-2.
