BRL this week. The DWR has indicated that BRL may need additional augmentation plans to address plans proposed in that TR. Any augmentation plans required by the DW R will need to be in place prior to approval of TR-32 for the Bowie No. 1 permit. BRL has estimated that 136.6 acre-feet of water will be consumed annually at the Bowie No. 2 Mine in conjunction with the production of 5 million tons per year of coal. This water depletion estimate was forwarded to the U.S. Fish and Wildlife Service (via OSM) for consideration of payment into the Colorado Endangered Fish Recovery Fund. No response has been received from USFWS yet. If USFWS requires a contribution to this fund from BRL, such a contribution will be required in order for PR-03 to be approved. For those water discharges that result from this permit revision, BRL must ensure no damages occur to senior water users as a result of decreased water quality... discharges of total dissolved solids, metals, changes in pH, and other pollutants must be found to have no impact on downstream water resources. The discussion of probable hydrologic consequences in Section 2.05.6(b)(iii) of the mine permit is being revised in PR-03 to address possible impacts of the relocated sediment pond and addition of the coal stockpile. However, since mining operations proposed in PR-03 will not significantly affect the {ikelihood or quality of any future mine water discharge, that portion of the Probable Hydrologic Consequences section of the permit is not being revised in PR-03. Although BRL does not expect to encounter significant amounts of ground water while mining, the permit currently assumes a continuous mine water discharge of 175 gallons per minute for purposes of discussing hydrologic impacts of mine water discharge. Should a mine water discharge result from the Bowie No. 2 Mine, the water discharged from the mine will be routed to the North Fork without impacting any irrigation canals. Impacts on water quality in the North Fork are projected to be minimal, and would not impair any existing uses of North Fork water. The DMG agreed with BRL's projections of hydrologic impacts due to mining when the permit was issued in 1996. BRL projects that a continuos 175 gpm discharge would raise the total dissolved solids(TDS) in the North Fork at its lowest historic flow from 160 to 200 ppm. A TDS content of 100 ppm is roughly equivalent to a specific conductivity of 297 umhosicm in the North Fork near the Bowie No. 2 Mine. This is well below the DMG's suspect level for material damage to irrigated fruit crops, which is a specific conductivity of 700umhos/cm .The TDS level would be much lower during irrigation season due to dilution by higher river flows.
