2009 AHR Page 6 <br />The 2009 TDS discharge represents 0.04% of the 1.69 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.
