STATE OF COLORADO <br />DIVISION OF RECLAMATION, MINING AND SAFETY <br />Department of Natural Resources <br />1313 Sherman St., Room 215 <br />Denver, Colorado 80203 <br />Phone: (303) 866-3567 <br />FAX: (303) 832-8106 <br />May 19, 2011 <br />Mr. Kurt Blunt <br />Environmental Supervisor <br />Colowyo Coal Company <br />5731 Highway 13 <br />Meeker, CO 81641 <br />Re: Colowyo Coal Mine, C1981-019, 2010 Annual Hydrology Report Review <br />Dear Mr. Blunt: <br />COLORADO <br />D I V I S ION OF <br />RECLAMATION <br />MINING <br />SAFETY <br />John W. Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Loretta E. Pineda <br />Director <br />The Division has reviewed Colowyo Coal Company's (CCC) 2010 Annual Hydrology Report (AHR) for <br />the Colowyo Coal Mine. Colowyo Coal Company submitted the 2010 AHR on March 24, 2011 in <br />accordance with the approved permit and Rule 4.05.13(4)(c). The following comments and concerns <br />were identified by the Division during the review of the 2010 AHR: <br />SECTION 1 <br />General Discussion <br />The text in the permit application indicates that sediment in sediment ponds will be surveyed <br />(page 4.05-14). In 2010, was this survey completed? If not, please explain why this was not <br />necessary. <br />2. Data from DMRs was not provided in the AHR, but a review of this data was deemed to be <br />important when assessing CCC water quality. Therefore DRMS reviewed this data and found <br />that there was only one day all year when parameters exceeded effluent limitations i <br />CDPHE permit: on May 4, 2010, there were elevated level of Iron in discharge from Prospect <br />Pond (CDPS point 007A) and elevated level of TSS in discharge from West Taylor Pond <br />(CDPS point 011A). Please explain if a report was filed with CDPHE, or, if not, why it was not <br />filed. <br />SECTION 2 <br />Rule Requirement - Rule 4.05.13(4)(c) <br />3. Subparagraph (i) - The word "quality" should be "quantity." <br />4. Subparagraph (ii) - The word "three" in the first sentence should be "four." <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines <br />
