Colorado Department of Health <br />February 26, 1993 <br />Page Two <br />Discharge resumed at outfall 002 in December 1992 with a higher salt <br />loading rate than the projected long term rate. Currently, the best <br />that we could look at would be salt reduction with the projected salt <br />loading at a production level of 320,000 clean tons per year. In this <br />case, costs would range from $2.25 to $10.94 per ton of coal mined. <br />In a spot coal market of approximately $15.00/ton, this would amount <br />to a 15$ to 73~ increase in the cost of coal. We do not believe that <br />this magnitude of increased operating costs can be justified at this <br />operation. <br />As you review this report, let me know if you have any questions. <br /> <br />LMR:jP <br />cc: Janet <br />W.
