' duet suppression inside the mine. The addition of 7.3 acre-feet per year. however. is consumptive use by the coal preparation plant. The consumptive use of the coal preparation plant maq increase proportionally ae coal production increases. as shown on Table 4. to a ' meaimum of 12.0 acre-feet per year. based upon a projected maaimum of 500.000 tone of clean coal processed by the preparation plant. Energy Fuels estimates that the mine may produce this tonnage from 1986 until the completion of mining in 1996. J Domestic Dses Domestic facilities include offieea. changing room with showers. cafeteria. and lavatories. The City of Florence currently is providing domestic water to the mine. with the water transported by tank trucks. I The records of water hauled indicates that an annual requirement Eor 1985 would be 1.4 acre-feet. The domestic water system uses a leachfield to 1 return effluent to the ground water system. With a consumptive use rate of ten percent. [he annual consumptive use of water by the domestic facilities is 0.1 acre-feet. Since there is no outside irrigation and the wrk force does not fluctuate seasonally. this rate of consumptive use remains constant throughout the year. If the domestic water use increases 1 proportionally with the increase of mine production, a use of 2.4 acre-feet and a consumptive use of 0.2 acre-feet annually could be I ezpected for future domestic water requirements. It should be noted since domestic water ie hauled from outside of Che Newlin Creek Basin. that a credit against consumptive water use of the total mining operation can be taken for the consumptive use and the flows returned to the stream system _ from the imported water. Dust Suppression Inside ~[ine l Water is required for duet suppression inside the mine. The amount of water used for inside duet suppression can be estimated by analyzing the -20-
