Fire Mountain Canal Concerns • Loss of water quality and National Pollutant Dischazge Elimination System (NPDES) related exceptions for our water due to contamination from Mine-related discharges. • Damage to the Canal and subsequent loss of the Canal due to additional inflows into the Canal caused by the design, construction, and operation of the Mine's drainage and storm water control systems. Recommendations • Ensure that Mine-related dischazges do not end up in the Canal. See additional recommendations below. • Ensure that Mine-related drainage facilities and their operation do not cause damage to the Canal that could result in its failure. See additional recommendations below. Pond F: Concerns • Contrazy to design, a permanent controlled dischazge line from Pond F was not installed during construction. Also, as designed, the discharge pipe would have discharged directly into the Canal (which is unacceptable) instead of into the Deer Trail Ditch as shown in the discharge permit. Instead, the Mine is proposing to pump water from this pond to the draw just west of the pond. • As currently situated, emergency spills in excess of the available capacity of the Deer Trail Ditch will end up almost immediately in the Canal. This is unacceptable. The placement of Pond F and the routing of flows to Pond F from the drainages that are being blocked by the coal wash station spoil effectively bypass a 4-foot diameter cross drainage culvert for those drainages under our Canal. • Pond F is directly above a portion of the Canal in an azea of steep slopes. Our Canal was lined in this area to reduce seepage and the potential for loss of the Canal. The unlined pond has the potential to increase seepage in that azea which in turn will increase the possibility of Canal failure. Recommendations • Install a permanent controlled dischazge line or permanent pump that dischazges to the draw at the west end of Pond F (outfall 006) rather than using a temporary pump or discharging to Deer Trail Ditch. This would take advantage of the existing culvert under the Canal for this draw. • Relocate the emergency spillway to the west end of the pond so that all spills also go to the draw at the west end of the pond. This would also take advantage of the existing culvert under the Canal for this draw. • Ensure that the culvert for this draw under the highway is cleaned and maintained so its full capacity is available. • Consider lining Pond F to prevent seepage that might adversely affect the Canal and property downhill of the Canal.
