production was 600,000 tons per year. At this rate, water needs were about 65 acre feet per year. <br />The Annual Hydrology Reports contain specific data on the amount of water consumed annually <br />at the mine since 1982. <br />Table 33 Summary of Mountain Coal Company's Water Rights for the West Elk Mine <br />Source of Water Water Ri hts <br />Mt.

These facilities have not yet been consWCted <br />Water used at the West Elk Mine comes from adjudicated water rights owned by Mountain Coal <br />Company. Table 33 summarizes Mountain Coal Company's rights. The rights are used according to <br />Colorado Water Laws administered by the District No. 4 Water Commissioner. <br />Raw or untreated water is pumped underground from the freshwater pond (FW-1) by pumps located <br />in the water treatment plant. <br />The water distribution system at the West Elk Mine contains several major components. They are <br />the raw water intake gallery and pumps, cast or steel utility piping, fresh water storage pond (FW- <br />1), water treatment plant, mine water pumps, a 1.2 million gallon mine water storage tank, <br />freshwater pump, potable water tank, and fire suppression systems. A second freshwater pond (FW- <br />2) has not yet been built. However, its construction is still planned to meet future storage needs. <br />Water pumped underground is used for dust suppression and to maintain fire fighting systems. <br />Currently, none of the water seeping into the mine is used in the mine. Thus, the water inflows aze <br />pumped out of the mine, treated, and discharged according to NPDES permit requirements. <br />Because the seepage is small, occurs near the outcrop, and fluctuates seasonally, it is not usable. <br />However, if water is encountered in the future in such quantities that it can be used ht the mining <br />operations, it will be used when that particulaz water right is in priority. <br />2.05-20 Revised Sep. ]995 TR77; Revised Oct. 7995 MR170 <br />
