2014 AHR Page 6 <br />Consumptive Use <br />Consumptive use during the year was for dust suppression and culvert maintenance. No <br />records of this minor amount of consumptive use are available. <br />Impacts <br />The average total dissolved solids for the mine discharges calculated with total flow for the Year <br />yields the tons of TDS discharged for the year. Outfall 016 discharged a total of 779 tons of <br />TDS to the river during the Year. <br />The 2014 TDS discharge represents 0.056% of the 1.38 million tons calculated to be carried by <br />the River. At the Roadside South Portal, water is expected to perpetually discharge through <br />outfall 016. <br />There was no detectable effect of mining on flows in Cottonwood and Rapid Creeks. Mining <br />ceased at the Roadside Portals on December 2, 1999. No further mining from either portal is <br />anticipated in the foreseeable future. <br />Consumptive use will be insignificant in the future because mining and washing of coal has <br />ceased. Consumptive use will be for seeding and dust control during reclamation operations. <br />
