Impacts <br /> <br /> <br /> <br /> <br /> <br /> <br />r <br />The total dissolved solids for the mine discharges calculated with monthly TDS and <br />monthly flow for the.Year come out to be 35.85 tons for 001, 817.46 tons for 002, and <br />285.68 tons for 004 for a total of 1138.99 tons. The following table presents the total <br />TDS discharged from the mine during the three prior years. <br />Outfalls 001, 002 & 004 <br />Water Year 1995 1996 1997 1998 <br />TDS (Tons) 1193.6 1163.7 1805.5 1138.99 <br />The 1997 TDS discharge represents 0.06 % of the 1.809 million tons calculated to be <br />carried by the River. Long term discharge from the Roadside North will cease upon <br />completion of mining. At the Roadside South, water is expected to continue to <br />discharge from 002 beyond closure and flow is expected to increase by the amount <br />previously discharged from outfa11001 and the amount previously used for mining and <br />processing. <br />' There was no detectable effect of mining on flows in Cottonwood and Rapid Creeks. <br />Mining projections in the Roadside South have been put on hold and discharges will <br />' return to near normal when the pane( to the East fills with water and overflows. An <br />increase in inflows is expected as mining progress west and north in the Roadside <br />North Portal, but is not expected to significantly influence the flow in the Creeks. <br />' Consumptive water use continued to be closely tied to production and is expected to <br />show similar trends in the future. <br />'• <br /> <br />4 <br />AHR 98 Page 9 5-1-99 <br /> <br />
