structures within the permit azea. Therefore the Division proposes [o approve <br />[hose activities. (4.04(6)). Refer to Section B, XVII of this document for <br />further information regarding the support azea. <br />III. Hydrologic Balance -Rule 4.05 <br />A. Water Quality Standards and Effluent Limitations <br />Most of the disturbed azea drains to one of two sediment ponds. These <br />ponds function properly to ensure that applicable water quality standazds <br />and effluent standazds aze met. <br />2. The Division has approved various small azea exemptions from use of <br />sediment ponds due to the limited size of the azeas, the fact that ponds and <br />treatment facilities are not necessary for the drainage to meet the effluent <br />limitations of Rule 4.05.2, and applicable State and Federal water quality <br />standards for receiving streams, and also due to the fact that no mixing of <br />surface drainage with a discharge from underground workings will occur. <br />The small areas exempted aze located at the shop area, the remaining topsoil <br />pile, the area above the Homestead Ditch, an area adjacent to County Road <br />179, and an azea along the lower margins of the Mine 3 South reclamation. <br />These azeas aze shown on Map No. 4a (4.05.2(3)(b)(i)). <br />B. Diversions and Conveyance of Overland Flow <br />Sediment control ditches have been designed and constructed in compliance <br />with Rule 4.05.3. Locations aze shown on Map 4a, and designs aze <br />discussed at Exhibit 3 of the permit document. The Homestead Irrigation <br />Ditch traverses the Mine No. 3 South azea, and the location is also shown <br />on Map 4a (4.05.3(2)). <br />C. Sedimentation Ponds <br />CYCC has constructed two sediment ponds, the Mine No. 3 North (M3N) <br />pond and the Mine No. 3 South (M3S) pond. <br />The M3N pond is located at the previous location of the south edge of the <br />reclaimed Middle Creek Portal Pit. Runoff was directed into the pit during <br />reclamation. During the final phase of backfilling and grading of the pit, <br />the pond was constructed to serve as a sediment control structure. The <br />M3S pond is located northwest of and functions as the sediment pond for <br />the now reclaimed Mine 3 South azea. <br />CYCC proposed that these ponds would function as treatment facilities <br />during mining and reclamation, and as permanent stock watering ponds <br />upon completion of reclamation. The ponds have been designed, <br />13 <br />
