separately or cumulatively, since there are no <br /> bedrock water supply wells completed in the <br /> region hydrologically adjacent to the mines. <br /> Also, the potential for impacting future use of <br /> bedrock ground water is low due to the depth of <br /> drilling required and to the problems of <br /> accessing steep slopes on private and U.S. Forest <br /> Service land. <br /> The quality and quantity of the alluvial aquifers <br /> of Fourmile Creek, Thompson Creek and Coal Creek <br /> will not be cumulatively impacted during the <br /> first 5-year permit period of the three mines. <br /> There is a possibility of qualitative and <br /> quantitative impacts on Coal Creek in the distant <br /> future when and if, the North Thompson Creek <br /> Mines progress into the Coal Creek Drainage. <br /> There is a minor potential for the Coal Basin <br /> Mine loadout and the North Thompson Creek Mine <br /> loadout to cumulatively impact the quality and <br /> quantity of ground water in the Roaring Fork <br /> alluvium, since both loadouts are located on this <br /> alluvial body. However, both of these loadouts <br /> have limited surface disturbance, small amounts <br /> of disturbed drainage to handle, and much of the <br /> disturbed drainage water is going into total <br /> containment lined ponds. Therefore, that minor <br /> amount of polluted drainage which may escape from <br /> the drainage control system will negligibly <br /> impact the quality of the vast amounts of Roaring <br /> Fork alluvial water. <br /> The greatest cumulative ground-water impact will <br /> be the indirect depletion of surface-water flow <br /> through the ground-water system to the mine <br /> workings. The surface mining operations proposed <br /> under the application have been designed to <br /> prevent damage to the hydrologic balance in <br /> associated off-site areas.

After reviewing the description of the proposed permit area, CMLRD <br /> and OSM determines this area is: <br /> a. Not included within an area designated unsuitable for surface <br /> coal mining operations. [2.07.6(2)(d)(i) , see page 63 of <br /> CMLRD's Decision Document] <br /> b. Not within an area under study for designating lands unsuitable <br /> for surface coal mining operations. [2.07.6(2)(d)(ii)] <br /> C. Not on any lands subject to the prohibitions or limitations of <br /> 30 CFR 761.11(a) (national parks, etc.) , 761.11(f) (public <br /> buildings, etc.) , and 761.11(g) (cemeteries).
