• Domestic Uses Water used in the office/bathhouse facilities is potable water hauled entirely from the City of Florence. The water is stored in a cistern, and after use is discharged through a treatment system into a leachfield. Consumptive use is considered to be 10~ of total consumption (Brogden, 1986). For the period of record, consumptive use was 0.15 AC=FT. Since domestic water is imported from outside the Newlin Creek Basin, the portion not consumptively used is shown as a credit against consumptive use (see table 7). Mining Dust Suppression Water is diverted from the surface water handling system to the underground mine for mining dust suppression and coal transporta- tion. Surface moisture on the in-place coal also contributes a minor portion of dust suppression water. Moisture remaining on the raw (run-of-mine) coal transported to the surface is considered con- sumptive use. Total consumptive use was 10.0 AC-ET for the period of this report (refer to Table 7). Determination of water consumption is based on analytical data derived from whole core sample moistures and raw coal sample moistures. Laboratory analysis of whole core samples indicate that 8.338 of the coal weight is specific retention moisture. Water removed with the raw coal from the Mine, specific reten- tion, is "mined" water, or water which is not an active part of the surface water system (Brogden, 1986). Consumptive use, therefore, is the weight difference between the total moisture of the raw coal (10.5$) and specific retention (8.330 , or 2.17$. Calculated consumptive use is based on 626,005 raw tons produced for the period of record. Outside Dust Suppression Water utilized for dust suppression on the Mine haul road and yard area is a consumptive use. Road watering averages a use of approximately 4,000 gallons per day, 21 days per month during nine months annually. The resulting consumptive use was there- fore 2.3 AC-FT for the period of record (refer to Table 7).
