42.04 APPLICATION FOR PERMIT FOR SIIRFACE OR UNDERGROUND MINING ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES. <br />• 2.04.6 Geology Description. <br />(2) (a) (Cont'd.) <br />(iii) (B) The location and extent of subsurface <br />water as defined by exploration drill- <br />ing, underground monitoring, and well. <br />monitoring is described in Section <br />2.04.7. Due to the stratigraphic in- <br />fluence upon groundwater occurrence, <br />intersection of the regional water ta- <br />ble and mine workings is not anticipat- <br />ed to occur within the permit area. <br />(C) Total sulfur content of the "D" coal <br />seam is generally below 0. 5% with the <br />following sulfur forms present: <br />pyritic sulfur = 0.02% <br />sulfate = 0.00% <br />organic sulfur = 0.38% <br />as received basis. Low concentrations <br />• of the potentially reactive sulfides <br />(pyrite or the polymorph marcasite) <br />seemingly preclude any potential for <br />acidic mine drainage. <br />Roof, floor, and interburden samples <br />representative of waste rock at the Or- <br />chard Valley Mine have been collected <br />and analyzed employing the Division's <br />guidelines. The sample locations are <br />depicted on Map 6A-8 and portray typi- <br />cal waste rock lithologies expected to <br />be encountered within the permit term. <br />The chemical constituents, listed in <br />Volume 6A are keyed to the Orchard Val- <br />ley Mine Roof and Floor Sample Location <br />Map 6A-8. <br />Rock samples were taken where obvious <br />contamination could have been intro- <br />duced into the run-of-mine product. <br />The samples were obtained by chipping <br />an adequate amount (2000 to 3000 grams) <br />Revised 08/01/84 <br />• Revised 12/26/84 <br />Corrected 10/12/86 <br />Revised 10/01/87 <br />23 <br />
