RULE 2 - PERMITS <br />minimal SLlpporting water requirements. The discussions presented in Section 2.04.7, Hydrologic <br />Description. indicate that while surface and ground \\ater resources are limited In those areas to be <br />affected by PSCNJ operations. they \\ill be adequate in terms of both quantity and quality to support <br />the designated postinimng land use. Given the proposed postininlng use. PSCM currently has no <br />plans to transfer any exploration borcholes of rnollltorin`� \\CIiS fOr Subsequent use aS water \\ells. <br />Potential Effects on Sediment Yields, flooding, Stream Floii s, and Surface or Ground Water <br />Availability - All temporary and permanent diversions within the PSCNI permit area have been <br />dcsioned and either have been or will he Constructed to maintain effective floe' Lllldcl' all anticipated <br />conditions. Increased t'Llnoff and sediment yield from disturbed areas is minimal in comparison to <br />the overall watershed. and \vlll be effectively mitigated by sedimentation ponds.

No subsidence is anticipated to OCCUr during the first <br />permit term. in \\-filch all illlnlllg \\ill be conducted with continuous minln`o machines. future <br />permit renewals will address subsidence impacts to surface and (,round water resources as heeded. <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 Illonitorino locations and elevations. <br />• Existing and proposed sedimentation ponds and impoundments <br />• Cross-sections for sedimentation ponds, impoundments, and Mille development waste piles. <br />Hydrologic Monitoring Plans for Evaluation of Hydrologic Consequences — PSCM currently <br />maintains. and will continue, a comprehensive progl'ain to monitor surface and gl'ollnd\\ater quality <br />and gLlantity for the duration of the proposed mining and reclamation operations. The illonitoring <br />program serves as an integral part of PSCM'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 />Midterm Review 2.05-92 Revision 04/2013 <br />
