The Pittsburg & Midway Coal Mining Co. <br />A ChevronTexaco Company <br />4601 DTC Boulevard, Sizlh Floor, Denver, CO 80237 ~ Phone (303) 9303600 <br />December 5, 2002 <br />Mr. Tom Kaldenbach <br />Colorado Department of Minerals and Geology <br />1313 Sherman St. <br />Room 215 <br />Denver, CO 80203 <br />Dear Tom, <br />RECf~Ii/E® <br />DEC 0 6 2002 <br />Givision df Mirteralsenrf'F'8idogq <br />Division of Minerals and Geolog;~ <br />P&M has received a modification to the CDPS Permit No. CO-0032638, changes <br />effective Januazy 1, 2003, copy enclosed. The changes incorporate the revised Regulation <br />33, changing the numeric standard for iron, manganese and sulfates to Water Supply <br />(WS). Supporting information indicates the relevant segment of Trout Creek is not in use <br />as a Water Supply, therefore testing for iron, manganese and sulfates will no longer <br />occur. <br />Additional modifications to the permit involve changes to the WET test monitoring, <br />primarily intended to reduce the sampling time requirements and eliminate confusion <br />over the timing of the acute and chronic testing which exists in the current permit. <br />If you have any questions regazding these changes, please give me a call. <br />If we don't get a chance to talk again before year's end, I hope you and your family have <br />a wonderful holiday season. <br />Sincerely, <br />Steven E. Leach <br />Sr. Environmental Engr. <br />cc: S. Linse - WWC <br />C. Miller - MWMS <br />C. Thiel - CT&E <br />
