II. Support Facilities - Rule 4.04 The only support facility at this site is the office, warehouse and equipment storage area located south of, and adjacent to. County Road No. 33. Construction of support facilities did not result in damage to any preexisting structures within the permit area. Therefore the Division proposes to approve those activities. (4.04(6)1. Refer to Section B, XYII of this document for further information regarding the support area. III. Hydrologic Balance - Rule 4:05 Water Quality Standards and Effluent Limitations 1. Most of the disturbed area drains to one of two sediment ponds. These ponds function properly to ensure that applicable water quality standards and effluent standards are met. 2. The Division has approved various small area exemptions from use of sediment ponds due to the limited size of the areas, the fact that Donds and treatment facilities are not necessary for the drainage to meet the effluent limitations of Rule 4.05.2, and applicable State and Federal water quality standards for receiving streams, and also due to the fact that no mixing of surface drainage with a discharge from underground workings will occur. The small areas exempted are located at the shop area, the remaining topsoil pile, the area above the Homestead Ditch, an area adjacent to County Road 179, and an area along the lower margins of the Mine 3 South reclamation. These areas are shown on Map No. 4a. (4.05.2(31(b)(i)). Diversions and Conveyance of Overland Flow Sediment control ditches have been designed and constructed in compliance with Rule 4.05.3. Locations are shown on Mao 4a, and designs are discussed at Exhibit 3 of the permit document. The Homestead Irrigation Ditch traverses the Mine No. 3 South area, and the location is also shown on Map 4a. (4.05.3(2)1. Sedimentation Ponds 1. CYCC has constructed two sediment ponds, the Mine No. 3 North (M3N) pond and the Mine No. 3 South (M3S) pond. The M3N pond is located at the previous location of the south edge of the reclaimed Middle Creek Portal Pit. Runoff was directed into the pit during reclamation. During the final phase of backfilling and grading of the Di t, the pond was constructed to serve as a sediment control structure. The M3S pond is located northwest of and functions as the sediment pond for the now reclaimed Mine 3 South area. - 13 -
