Potential effects of anticipated coal mining on salinity of the Price, San Rafael, and Green Rivers, Utah
The impact of anticipated coal mining in Utah on the salinity of the Price, San Rafael, and Green Rivers is to be addressed in the repermitting of existing mines and permitting of new mines. To determine the potential impacts, mathematical models were developed for the Price and San Rafael River basins. Little impact on the quantity and quality of streamflow is expected for the Price and San Rafael Rivers. The increase in mean monthly flow of the Price River downstream from Scofield Reservoir is projected as 3.5 cu ft/sec, ranging from 1.7% in June to 140% in February. At the mouth of the Price River, the potential increase in mean monthly flow is projected as 12.6 cu ft/sec, ranging from 3.7% in May to 37.7% in January. The potential changes in dissolved solids concentration would range from a 20.7% decrease in January to a 1.3% increase in June. At the mouth of the San Rafael River, the potential increase in mean monthly flow ranges from 2.9 cu ft/sec in February to 6.7 cu ft/sec in May, with the increase ranging from 0.8% in June to 12.6% in November. The potential changes in dissolved solids concentration would range from a 5.3% decrease in March to a 0.6% increase in May. The anticipated mining in the Price and San Rafael River basins is not expected to cause a detectable change in the quantity and quality of streamflow in the Green River. The projected peak increase in flow resulting from discharge from the mines is less than 0.3% of the average flow in the Green River. 18 refs., 6 figs., 17 tabs.
