White Pine Copper-An Environmental And Economic Assessment

The White Pine Copper Division of Copper Range Company is a large copper producer operating an underground mine, mill, and smelter on Michigan's Upper Peninsula. Principal water discharges are from the tailings basin where these discharges are high in dissolved solids because of mine water pumped into the basin. Principal air emissions are from the smelter where SO2 emissions are uncontrolled. Although water discharges and air emissions have not had significant environmental impacts, environmental regulations could require additional control procedures. Because of low copper prices and poor profitability, cost of compliance with possible new environmental regulations could have serious impact on White Pine with no apparent significant beneficial environmental impacts.
