roads were approved in Permit Revision No. 7. Both allow access to two new <br />material storage areas. <br />II. Support Facilities - Rule 4.04 <br />A. Construction of support facilities will not result in change, destruction or disruption of <br />oil, gas pipelines or water wells, nor will coal slurry pipelines or railroads be impacted. <br />Therefore, the Division approved those activities (4.04(6)). A list of approved facilities <br />may be found in Section 2.05.3(3) of the permit. <br />III. Hydrologic Balance - Rule 4.05 <br />A. Water Quality Standards and Effluent Limitations <br />The Division granted approval for small area exemptions from the use of <br />sediment ponds, due to the limited size of the areas and due to the fact that ponds <br />and 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 surface <br />drainage with a discharge from underground workings will occur. The locations <br />of the small areas to be exempted are discussed on Page 2.05 -32 of the permit <br />application and are shown on permit document Map 21 -1 and Map 95266 -02 <br />(4.05.2(3)(b)(i)). <br />Storm runoff from sixteen small areas at the mine site are subjected to alternate <br />treatment prior to leaving the permit area. The sixteen areas are 1.) the "material <br />storage area below Pond C, 2.) the pump station, 3.) the topsoil stockpile near <br />the Gob pile, 4.) the coverfill stockpile and coverfill topsoil stockpile near the <br />Gob pile, 5.) the area around the mine engineer's building, 6.) the Freeman <br />Gulch vent fan site, 7) the area underneath the conveyor, between old State <br />Highway 133 and the Fire mountain Canal and 8) nine small areas along the train <br />loadout railroad track outslopes. In addition, alternate sediment control measures <br />are employed at several methane de -gas drill pads. <br />2. The Division granted an exemption from the use of sediment ponds for drainage <br />from underground mine workings as long as no mixing with surface drainage will <br />occur and as long as ponds and treatment facilities are not necessary for the <br />drainage to meet effluent limitations of Rule 4.05.2 and applicable State and <br />Federal water quality standards for receiving streams (4.05.2(3)(b)(11)). <br />B. Diversions and Conveyance of Overland Flow <br />The Division does not propose to approve a permanent diversion (4.053(2)). <br />2. The Division approved construction of a diversion on an existing landslide <br />(4.053(4)). <br />C. Stream Channel Diversions <br />21 <br />
