42,05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES -- MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS. • 2.05.6 Mitigation of Surface Coal Mining Operation Impacts. (Cont'd.) (6) (b) (Cont'd.) communication with the development of mine workings. Subsidence features of the development entries could possibly reach the ground surface or base of colluvial material and drain these hydrologic resources. The a priori intent of these above mentioned lease stipula- tions is to prevent material damage to structures lo- cated within or adjacent to the permit area and the diminution of flows in Steven's Gulch, East Roatcap Creek, and associated Renewable Resource Lands where the overburden depth is 600 ft. or less. (i) (A) The pre- and post-mining land use of the permit area, as described in Sec- tions 2.04.3 and 2.05.5 are generally, rangeland, caildlife habitat, and recre- ation. A few summer homes, a restau- rant ("Muckleville"), a community do- mestic water system (Pitkin Mesa Pipe- line), several trails, a county road • (Steven's Gulch Road), CWI's waterline and pocuerline, and a 230 kV powerline also exist within or adjacent to the permit area. Other than CWI's facili- ties, these present land uses will con- tinue following cessation of operations at the Orchard Valley and Orchard Val- ley West Mines. The Renewable Resource Lands identified in Section 2.05.6(6)(a)(ii)(A) are col- luvial/alluvial deposits which contain groundwater and support willows, reed grass, and other riparian vegetation. (B) Predicted subsidence related phenomena within the permit area will be much less serious than the worst consequen- ces described earlier. Where sensitive features exist upon the surface (Muckle ville, Steven's Gulch, and East Roatcap Creek), protective pillars will be utilized to prevent subsidence related damage. .
