• 2.05.3 Run -off from the loadout disturbance is generally contained in two sediment ponds which contain the run -off from the batch weigh loadout and most of the disturbance to the east. Run -off from a transfer tower the disturbance associated with a conveyor support and the disturbed area along the western loadout track will not be contained in sediment ponds. There are six SAE areas (SAE10 through 15) where run -off will be filtered through a sediment fence before it leaves the permit area. Sample points for the SAEs will be located near the sediment fences. The design for the alternative sediment control devices are presented in Exhibit 8 beginning on pages Exh -8- 187,189, 197, 209, 234 and 236. Locations are shown on Map 20 and 39. A demonstration has been made that the vegetation is adequate to control erosion on SAE numbers 1 through 9. The SAE 9 grass filter demonstration begins on page Exh -8 -198. The SAE 1 -8 grass filter demonstration begins on page Exh -8 -231. During 2002, fourteen exploration holes were drilled to identify the burn line in the B- Seam. Hole locations are shown on Map 9, Hydrologic Monitoring Location Map. The Operator is considering constructing a new B -Seam portal in lieu of accessing the B- Seam through ramps from the D -Seam. An accurate location of the burn line is necessary to determine if a new portal is feasible. The explorations holes will be drilled with a small skid mounted drill. Hole diameters will be 6- inches or less. The average hole depth is 350 -feet with a range in depth from 80 to 510 feet. The holes will be sealed in accordance with Rule 4.07. Run -off from the drill pads and associated light use roads /trails will be contained by sediment ponds B & C. • During 2002, one exploration hole KM -3 was drilled to assess the presence of water in the old King Mine workings. The hole location is shown on Map 9, Hydrologic Monitoring Location Map. The hole was sealed in accordance with Rule 4.07. Run -off from the drill pads will be contained by a sediment fence as described above. During 2003, the Operator drilled five exploration holes. Three were drilled along Terror Creek and two were drilled in Stephens Draw. During 2003, the Operator drilled fourteen geotechnical holes and three alluvial wells for the proposed new gob pile. Drilling was from new light use roads so drill pads were not required. During 2004, the Operator did not drill any gob vent holes or exploration holes. During 2005, the Operator drilled five gob vent holes. During 2006 the operator drilled five gob vent holes. During 2007 the operator drilled six gob vent holes and one geotech hole along Hubbard Creek. The geotech hole was drilled from a drill site west of Hubbard Creek Road. A short section of access road was constructed from Hubbard Creek Road to the drill site. A portion of the access road to the drill site is within 100 feet of Hubbard Creek, a perennial stream. Rule 4.05.18 requires the DRMS make a finding that authorizes any proposed disturbance within 100 feet of a perennial stream. By letter dated March 2, 2007, to Bowie Resources, LLC, the DRMS made such a finding. The DRMS found the disturbance will not cause or contribute to the violation of applicable • water quality standards and that the water quantity and quality, as well as other MR -100 2.05-35- 04/09 APPRovc —,D 5 ///o9
