STATE OF COLORADO <br />DIVISION OF RECLAMATION, MINING AND SAFETY <br />Department of Natural Resources <br />1313 Sherman St., Room 275 <br />Denver, Colorado 80203 <br />Phone: (303) 8663567 <br />FAX: (303) 832-8106 <br />20 September 2006 <br />Mr. Tay Tonozzi <br />Colowyo Coal Mine <br />5731 State Highway 13 <br />Meeker, CO 81641 <br />Re: Colowyo Mine C-1981-019 <br />2005 Annual Reclamation Report Review- Report Sections 3-10 <br />Dear Mr. Tonozzi: <br />COLORADO <br />DIVISION OF <br />RECLAMAi ION <br />MINING <br />- &- <br />SAF EZ'Y <br />Bill Owens <br />Governor <br />Russell George <br />Executive Director <br />Ronald W. Cottony <br />Division Director <br />Natural Resource Trustee <br />The Division has received your 28 March 2006 submittal of the 2005 Annual <br />Reclamation Report and appreciates Colowyo's timely submittal of the report. The 2005 <br />Annual Reclamation Report binder also contains the 2005 Annual Hydrology Report. <br />Sections 1 and 2 of the binder contain the Annual Hydrology Report and Sections 3-10 <br />contain the Annual Reclamation Report. A review of sections 1 and 2 of the report <br />containing the 2005 Annual Hydrology Report will be sent under a separate cover. The <br />Division has reviewed the report and has the following questions and comments. <br />There is an addition error on the Division's Annual Reclamation Report form <br />in Exhibit 3A. Colowyo reports that the cumulative total disturbed acreage is <br />3,840.46 acres. The Division believes that the total should be 3,937.25 acres. <br />The formula for cumulative total disturbed acreage is acres in active mining <br />plus acres in long-term mining or reclamation facilities plus cumulative acres <br />backfilled and graded. Additionally, the cumulative total disturbed acres <br />listed on the ARR form (3,840.46 acres) is more than that permitted for the <br />life of the mine (3,837.00 acres). Please review the acreage numbers <br />reported on the form and make the necessary corrections and resubmit <br />the Annual Reclamation Report form in Exhibit 3A. <br />2. The seed mix and seed tag and invoice contained in Exhibits 4A, 4B and 4C <br />are all in agreement. There are very minor differences in the required <br />percentage of seed in the seed mix versus the actual percentage of seed in the <br />seed mix due to impurities and inert matter. The Division appreciates <br />Colowyo's detailed attention to this part of the reclamation plan. Attached is <br />a spreadsheet that shows the required seed mix percentages and the actual <br />seed mix percentages. The Division also notes that Pasture sage was <br />Office of Office of <br />Mined Land Reclamation ARive and Inactive Mines <br />
