<br />The Division has no further concerns at this time. In its submittal dated May 12, 1999, <br />BRL stated that it will use the temporary sediment control structures stated on page 2.05- <br />20 for those construction areas that do not drain to a sedimentation pond. These structures <br />include straw bales and silt fence, followed by reseeding and mulching when the <br />construction is finished. BRL also stated that the new pond B will be finished before the <br />present pond B is removed. Any discharge from the present pond B will be piped azound <br />the construction site for the new pond B. As a final point, the Division will be verifying <br />BRL's success at sediment control at the mine site in the field. <br />7. The Division believes thnt it is possible that the water in the Fire Mountain Canal cnn be <br />affected by the proposed mining operations. Field inspection shows that overflow from <br />the Deer Trail Ditch, at the point where the Terror Creek Loadout takes its venter from <br />the ditch, flows into the Fire Mocrntain Canal. Also, the water in the Fire Mountain <br />Canal nrcry be nffected through ground water contamination from the proposed coal <br />stockpile or from pond B, which receives runoff from the coal stockpile. Finally, surface <br />runoff from the entrnnce road area appears to be able to flow into the Fire Mountain <br />Canal. The Division requests that BRL propose the locations for upstream and <br />downstream monitoring stations in the Fire Mocrntain Canal to monitor water quality <br />and quantity in that canal. <br />BRL has committed to establishing upstream and downstream monitoring locations for <br />the Fire Mountain Canal. This commitment is stated on revised page 2.05-77 and Map 9, <br />both contained in the submittal dated lvlay 12, 1999. Concerning the possible relocation <br />of the downstream monitoring point for the Deer Trail Ditch, BRL stated, in the submittal <br />dated August 30, 1999, that the downstream monitoring point is located where the water <br />in the Deer Trail Ditch is dumped into the Fire Mountain Canal. There is very little water <br />in the Deer Trail Ditch below this point. Field inspections by Division personnel in the <br />past have confirmed this. <br />8. Please provide a detailed demonstration and a discussion in the probable hydrologic <br />consequences section of the permit application that the alluvial ground water will be <br />protected from contamination from the proposed coal stockpile. <br />BRL has adequately answered all of the issues presented by the Division's original comment, <br />with the exception, possibly, of the alluvial wells, and with the proposed coal stockpile <br />leachate analysis. <br />In the submittal dated May 12, 1999, BRL had addressed the Division's original concern <br />regazding alluvial groundwater monitoring downgradient of the proposed Pond B and coal <br />stockpile by adding wells AW-7, AW-8, and AW-9 to Map 15-1. In the submittal dated <br />August 30, 1999, BRL added wells AW-7, AW-8 and AW-9 to the hydrologic monitoring <br />requirements on revised permit application page 2.05-78 and to Map 9, Hydrologic <br />Monitoring Location Map. However, during the Division's field inspection of August 26, <br />5 <br />
