State Reg. <br /> <br />(see Exhibit 7-15). Thirteen of these are registered to the <br />Seneca II Mine (accounting for 299 acre-feet from Grassy Creek <br />and 19.03 acre-feet from the Fish Creek drainage). It is not <br />anticipated that the mine surface water usage will affect <br />senior surface water rights in the Grassy Creek and Fish Creek <br />Basins because only small portions of the watersheds will be <br />affected and there has never been a call for water on Grassy <br />Creek. <br />There are fifteen registered ground water rights in the <br />vicinity of the Seneca II Mine. One, GW-12, the old Seneca <br />Coal Well, has been abandoned; however, the right was not <br />transferred to GW-15, the replacement Seneca Coal Well. In <br />terms of future uses of ground water and surface water in the <br />vicinity of the Seneca II Mine, domestic water supply via <br />ground water would be the most probable. This is because <br />according to United States Soil Conservation Service personnel, <br />the Grassy Creek Basin below the mine is not capable of being <br />flood irrigated (Alluvial Valley Floor, Appendix 7-7). Mosi <br />domestic supplies locally are from ground water. Due to the <br />closed nature of the yround water basin and low <br />transmissivities of the affected strata, it is highly unlikely <br />that mining will affect any new wells drilled. <br />In conclusion, as shown in Section 7-111 "Probable Hydrologic <br />Consequences", mining of coal will not to any great extent <br />contaminate, diminish or interrupt current sources of ground and <br />surface water in the adjacent area. <br /> <br />7-151 Revised ii 7; 24/90 <br />
