The area currently within the proposed permit boundary is outlined on <br />• the Drainage and Sediment Control Plan (Map 7). Platurally occurring <br />soil and rock materials will be excavated and placed as the containment <br />embankment. <br />After construction of the containment embankment, the embankment as well <br />as excavation will be seeded as stabilization. <br />Typical cross-sections and design layouts are shown on the Drainage and <br />Sediment Control Plan (Map 7). Specifications and design criteria <br />details are found in Exhibit 7, Drainage and Sediment Control Plan. <br />Stream Channel Diversions <br />No intermittent or perennial streams are diverted or will be relocated <br />by Mt. Harris as none exist in the facility area. <br />• Discharge Structure <br />There will be no discharge from the Mt. Harris Coal Company. <br />Permanent and Temporary Impoundments <br />The containment berm and sedimentation pond will be left intact at final <br />reclamation of the Mt. Harris Coal Company. <br />Surface Water Monitoring <br />The proposed drainage and sediment control plan is designed to allow no <br />discharge from the 10-year, 24-hour precipitation event. Since no <br />discharge will take place, no NPDES permit is required. <br />Groundwater Protection <br />• The only excavation planned at the Mt. Harris Coal Company will be for <br />the sedimentation pond as outlined on the Drainage and Sediment Control <br />2.05.6-4 <br />
