• required. As required by Part 4.05.2, all runoff from disturbed areas will be passed through a system of sedimentation ponds. The sedimentation ponds are discussed in Sections 2.05.3, 2.05.6, and 4.05.6 and specific design methodology and calculations are presented in Exhibit 19, Drainage and Sediment Control Plan. In addition to the reclamation techniques and mitigation methods described and referenced in this section, further protection of the hydrologic balance is achieved through comprehensive and ongoing water monitoring programs conducted to detect any significant changes in surface and groundwater quantities or quality. The hydrologic monitoring plan is discussed in Section 2.05.6, Mitigation of Surface Coal Mining Operation Impacts and specific plan details are presented in Exhibit 25, Hydrologic Monitoring Plan. 4.05.2 WATER QUALITY STANDARDS AND EFFLUENT LIMITATIONS • EFCI plans for control of drainage and sediment as described in Sections 2.05.3, 2.05.5 and 2.05.6, provide for all surface drainage from disturbed lands in the permit areas to be passed through sedimentation ponds prior to release to natural drainages. The sediment control plan reflects the use of diversion or collection ditches to either divert runoff from undisturbed areas around affected areas or to route disturbed area drainage to sedimentation ponds. All ponds have been designed and are maintained and monitored to meet the standards of Part 4.05.6. Additional information relative to sediment control plans is presented in Sections 2.05.3, 2.05.6, 4.05.5, 4.05.6, 4.05.7, 4.05.9, and 4.05.17. EFCI will continue to operate and maintain sedimentation ponds and associated drainage structures until contributing drainage areas are effectively restored through application of the reclamation practices described in Section 2.05.4, Reclamation Plan. Effective restoration will • 4.05-4
