RULE 2 - PERMITS <br />The primary postmining land use in the mine permit and adjacent areas will be undeveloped land <br />used primarily for wildlife habitat and limited livestock grazing. The proposed use involves <br />minimal supporting water requirements. The discussions presented in Section 2.04.7, Hydrologic <br />-Description, indicate that while surface and ground water resources are limited in those areas to be <br />affected by PSCM operations, they will be adequate in terms of both quantity and quality to support <br />the designated postmining land use. Given the proposed postmining use, SCCC currently has no <br />plans to transfer any exploration boreholes or monitoring wells for subsequent use as water wells. <br />Potential Effects on Sediment Yields, Flooding, Stream Flows, and Surface or Ground Water <br />Availability - All temporary and permanent diversions within the PSCM permit area have been <br />designed and either have been or will be constructed to maintain effective flow under all anticipated <br />conditions. Increased runoff and sediment yield from disturbed areas is minimal in comparison to <br />the overall watershed, and will be effectively mitigated by sedimentation ponds. Stream flows and <br />water availability will be minimally affected. No subsidence is anticipated to occur during the first <br />permit term, in which all mining will be conducted with continuous mining machines. Future <br />permit renewals will address subsidence impacts to surface and ground water resources as needed. <br />Mapping of Hydrologic Protection Information - Information presented on the regional and <br />facilities area maps and drawings, which addresses hydrologic protection issues, includes: <br />• Receiving surface water drainages. <br />• Diversion, collection, treatment, storage, and discharge facilities and structures. <br />• Water monitoring locations and elevations. <br />. • Existing and proposed sedimentation ponds and impoundments <br />• Cross - sections for sedimentation ponds, impoundments, and mine development waste piles. <br />Hydrologic Monitoring Plans for Evaluation of Hydrologic Consequences — SCCC currently <br />maintains, and will continue, a comprehensive program to monitor surface and groundwater quality <br />and quantity for the duration of the proposed mining and reclamation operations. The monitoring <br />program serves as an integral part of SCCC's efforts to protect the hydrologic balance by providing <br />an accurate and timely method of identifying and quantifying any possible concerns with respect to <br />surface and ground water resources. <br />The hydrologic monitoring plan provides for a frequency and distribution of both baseline and <br />operational monitoring data collection adequate to identify and document baseline conditions, and <br />trends and fluctuations in the quantity and quality of surface water, the level and quality of ground <br />water, and the overall effects of mining and reclamation activities on the hydrologic balance. Water <br />quality params include field measurements for pH, specific conductance, and temperature and <br />laboratory measurements for general water quality characteristics such as TSS, TDS, major ions, <br />and selected trace metals. Both surface and ground water quality samples are collected, labeled and <br />transported to a qualified analytical laboratory for analyses. Proper sample collection, preservation, <br />handling, and storage methods will be utilized at all times to preserve the integrity of the samples <br />and assure the validity of the analytical results. The monitoring data and resulting evaluations are <br />used to identify any potential problems and develop any necessary supplemental mitigation <br />measures in a timely manner. The monitoring network, sampling frequency, and monitoring <br />params are described in section 2.04.7, Hydrologic Description. recharge /discharge /storage <br />characteristics. <br />PSCM Permit App. 2.05 -92 Revision 03/05/10 <br />
