RULE 2 - PERMITS <br />effective compliance with the following applicable regulatory requirements and consistency with <br />overall environmental objectives: <br />is • Minimize disturbances to the hydrologic balance <br />• Prevent material damage outside of the permit area <br />• Support the approved post- mining land uses <br />• Meet applicable Federal and State water quality regulations <br />Detailed discussions of specific potential impacts and proposed control and mitigation measures are <br />presented in the following sections. <br />As previously discussed, plans for PSCM's operations include standard hydrologic controls and <br />mitigation measures that are designed to prevent significant changes in the quantity and quality of <br />surface and ground water resources, preserve existing hydrologic functions, comply with regulatory <br />requirements, and limit adverse impacts to surface water or ground water users. These measures <br />include: <br />• Limiting surface disturbance areas. <br />• Proper design, construction, and grading of facilities areas and roads. <br />• Construction, operation, and maintenance of drainage and sediment control structures to <br />divert undisturbed runoff around disturbance areas, collect and route disturbed area runoff to <br />sedimentation ponds to allow settlement of suspended solids, and facilitate any treatment <br />which may be necessary. <br />• • Utilization of localized erosion control measures in any areas having high erosion potential. <br />• Initiation of reclamation operations as soon as practical following completion of mining or <br />when the associated facilities are no longer required to support ongoing mining and related <br />operations. <br />• Effective reclamation to minimize gradients, reestablish surface drainage patterns, restore <br />pre - mining runoff and infiltration characteristics, and establish an effective and self - <br />sustaining vegetative cover. <br />• Post - reclamation land use management. <br />During active operations, the designed drainage and sediment control system along with appropriate <br />surface grading and stabilization measures will be the primary mechanism used to provide effective <br />erosion and sediment control. A detailed discussion of this system is presented in Section 2.05.3, <br />Mine Facilities; the locations and configuration of drainage and sediment control structures are <br />shown on Map 2.05.3 -M4, Drainage and Sediment Control Plan, and Map 2.05.3 -M5, Operational <br />Channel Profiles; design information and calculations are provided in Exhibit 2.05.3 -E2, Drainage <br />and Sediment Control Plan. <br />Following completion of mining operations, reclamation of surface disturbance areas, restoration of <br />effective drainage, and revegetation as described in Section 2.05.4, Reclamation Plan, will be the <br />primary means of establishing both effective short and long -term erosion and sediment control. <br />Post - Mining Channel Profiles are located on Map 2.05.4 -M1, Postmining Topography. <br />• PSCM has incorporated specific control and mitigation measures in mining, processing, and <br />reclamation plans in order to prevent any significant impacts on surface or ground water quantity <br />and quality.
