Cattany <br />Grand Junction, CO 81506 Division Director <br /> Natural Resource Trustee <br />RE: North Thompson Creek Mine (C-1981-025) <br />2007 and 2008 Annual Reclamation Report (ARR) <br />Dear Mr. Stover: <br />The Division has received copies of the 2007 and 2008 Annual Reclamation Reports for <br />the North Thompson Creek Mine. Thank you for your timely submittal of these reports. <br />The original disturbed area for the North Thompson Creek Mine was 65.2 acres. Of this <br />area all of the acreage has undergone a Phase I and a Phase II Bond Release. An <br />additional 60.9 acres have undergone a Phase III Bond Release. The remaining areas are <br />in long-term facilities or have been reclaimed for 10 years or less. North Thompson <br />Creek has applied for a final bond release for the site (SL-06) but the Division has not yet <br />proposed a decision. <br />On the SL-06 inspection (on 17 April 2007) it was noted that three small sinkholes had <br />formed on the surface of the refuse pile. Additionally, it was noted that the Mine No. 3 <br />shaft backfill had collapsed. It was reported in the 2007 ARR that these areas were <br />backfilled and seeded and that they accounted for less than 0.1 acres, combined. On 2 <br />June 2008 the Division performed a follow-up inspection of these locations and noted <br />that the areas had been stabilized. The Division does not have any questions or <br />comments regarding the 2007 Annual Reclamation Report. <br />No reclamation or sampling activities were performed in 2008. The Division does not <br />have any questions or comments regarding the 2008 Annual Reclamation Report. <br />Sincerely, <br />James R Stark <br />Environmental Protection Specialist <br />cc: Sandy Brown <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
