I • 2.05.3 <br />Run-off from one or two of the loadout conveyor footings will not be <br />contained in a sediment pond. Run-off from the footings will be filtered <br />through a sediment trap such as straw bales, silt fences or other approved <br />devices. Two sediment ponds will contain the run-off from the batch weigh <br />loadout and most of the disturbance to the east. Run-off from the remaining <br />portion of the disturbed area along the loadout track will not be contained in <br />sediment ponds. There are thirteen SAE areas where run-off will be filtered <br />through a sediment fence before it leaves the permit area. Sample points for <br />the SAEs that have sediment fences will be located near the sediment <br />fences. Sample points for the SAEs at the culverts and ditches will be at <br />their respective outlets. The design for the alternative sediment control <br />devices are presented in Exhibit 8 pages ExhB- 187 through 189 and the <br />locations are shown on Map 20. <br />During 2002, up to twelve exploration holes will be drilled to identify the burn <br />line in the B-Seam. Hole locations are shown on Map 9, Hydrologic <br />Monitoring Location Map. The Operator is considering constructing a new <br />B-Seam portal in lieu of accessing the B-Seam through ramps from the D- <br />• Seam. An accurate location of the burn line is necessary to determine if a <br />new portal is feasible. The explorations holes will be drilled with a small skid <br />mounted drill. Hole diameters will be 6-inches or less. The average hole <br />depth is 350-feet with a range in depth from 80 to 510 feet. The holes will <br />be sealed in accordance with Rule 4.07. Run-off from the drill pads and <br />associated light use roads/trails will be contained by sediment ponds B & C. <br />MR-23 2.05 - 34 - 6/02 <br />
