Annual Hydrologic Report Page Eight The moisture added during mining million gallons and the moisture out to be 5.33 million gallons. plant was 3.18 million gallons, of domestic water being used in calculates out to be 3.35 added during cleaning calculates The metered mine water in the resulting in 2.15 million gallons the plant. For dust control on roads, both surface and underground, water was used as necessary. Magnesium Chloride was used on roads to better control dust and to reduce the watering requirement. Underground approximately 4800 gallons per day, 3 days per week were used and on the surface approximately 12,000 gallons per day, 4 days per week, 50~ of the year were used. The surface roads are watered with irrigation water from the Highline Canal. A summation of the estimated consumptive use of water is as follows: Total Gallons/ Gallons/ Source Gallons rhw ton clean ton Domestic Surface Facilities 1,397,000 2.8 4.9 • Preparation Plant Mine 2,150,000 4.3 7.3 Mining 3,350,000 6.8 11.7 Preparation Plant 3,150,000 6.4 11.1 Underground Roads 750,000 1.5 2.6 Highline Canal Surface Roads 1.250.000 2.5 4.4 TOTAL 12,047,000 24.3 42.1 Impacts The total dissolved solids (TDSj for the mine discharges calculates out to be 41.4 tons from outfall 001 and 449.0 tons for outfall 004. These discharges represent 0.035 of the 1.42 million tons calculated to be carried in the River. Discharge of TDS is expected to double when outfall 002 stabilizes. For the 1993 water year, we expect to see an estimated 800 tons of TDS from outfall 002 while an initial flushing of minerals takes place in the old works. Long term, the Cameo No. 1 Mine will be sealed with no discharge and the Roadside Mine will continue to discharge from 002. There was no detectable effect of mining on Cottonwood and Rapid Creeks. As projected in last year's AHR, the Roadside Mine inflows in the area of these creeks increased again due to . continued advance to the south and east. For the 1993 water
