<br />Intake Air Water Content <br />44.14 Grains/lb dry air (.2) = 8.83 Grains/lb Air <br />Exhaust Air Water Content = 64.36 Grains/lb Air <br />Loss <br />Calculation <br />= 55.50 Grains/lb Air <br />(550,000 cfm)(1440 min/day)(365 days/year) <br />(0,0626 lb/cu-ft)(55.5 grains H2O/lb Air) <br />(1/7000 grain/lb)(1/8.34 lb/gal) = 17,204,000 gal/yr <br /> <br />SUBSIDENCE EFFECTS ON SPRINGS AND SEEPS <br />There has been no subsidence related effects on springs and seeps, and <br />none is anticipated. Please refer to Section 2.05.6, Mitigation of the <br />Impacts of Mining Operations, Probable Hydrologic Consequences, for a <br />detailed discussion of the effects of mining on surface and ground water <br />hydrology. <br />COAL MOISTURE LOSS <br />Coal shipped from Empire Energy has an estimated 10 percent moisture <br />permanently entrained on the exterior of the coal particles. <br />Water Loss (WL) _ (4,000,000 TPY)(0.10 Moisture)(2,000 lb/ton)/(8.34 <br />lb/gal) = 95,900,000 gal/yr <br />DIRECT DIVERSIONS <br />• Empire Energy does not currently or plan to divert any surface water for <br />mine operational use. Therefore, there will be no streamflow depletion. <br />-4- <br />
