<br /> <br />No new haul roads, access roads, or light use roads are proposed for this permit revision. <br />No new findings for roads are required. <br />11. Support Facilities <br />No new surface facilities are proposed for this permit revision. <br />III. Hydrologic Balance <br />A. Water Quality Standards and Effluent Limitations <br />1. The Division proposes to grant small area exemptions from use of sediment ponds due to the <br />limited size of the areas and due to the fact that ponds and treatment facilities are not necessary <br />for the drainage to meet the effluent limitations of Rule 4.05.2 and applicable State and Federal <br />water quality 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 small areas to be <br />exempted are as follows: <br />AREA SIZE SEDIMENT CONTROL <br />Rock Dust 0.5 acre berm, rock filler, swale <br />Fish Creek Borehole 0.5 acre berm, rock filler <br />Fish Creek Vent 0.6 acre rock filter, vegetation <br />Pond B 1.5 acres veg, berm, rack filler <br />Power subst. < 1 acre berm <br />Rail Spur 2.75 acres silt fence/established vegetation <br />Warehse/shop 5.88 acres rock filler/established vegetation <br />Warehse No. 2 1.5 acres veg., rock filter <br />Tipple No. 2 < 1 acre rock filter/vegetation <br />Pond D east 0.7 acre veg/rock filter/sump <br />Pond D west 0.5 acre rcek filter <br />Pond T pile 0.5 acre rock filter <br />Overland belt 0.5 acre rock filter <br />FC Tipple <5 acres sump, rock filler <br />Rockfall Trenches 7.93 acres mulch/rock check <br />North Escape Shafr 1.82 acres mulch silt fence/rock checklbaleslveg. <br />EMD Ven[ 2.66 acres upland divert veg./gravel/mulch <br />EMD Treat Ponds 4.4 acres mulch veg. <br />SW Borehole 0.2 acres silt fence/rock filters <br />Grout Hole pad 2.5 acres sump, rock check dam <br />14 <br />
