TR36, Adequacy Review NO. 3 <br />Dear Mr. Nettleton: <br />The Colorado Division of Reclamation, Mining and Safety (Division) has updated the reclamation cost <br />estimate for the Williams Fork Mines. The last reclamation cost estimate was conducted on September 6, <br />2013 for Permit Renewal No. 6 (RN6). With the submittal of TR36 to address the adequacy review items <br />for RN6, Moffat County Mining provided the Division with several comments regarding the September, <br />2013 cost estimate. The Division responded to these comments with the first adequacy review letter for <br />TR3 6. <br />The enclosed reclamation cost estimate updates the tasks from the September, 2013 estimate with 2014 <br />prices. Also, MCM pointed out several items that were omitted from the last reclamation cost estimate <br />such as the reclamation of the Williams Fork Strip Pit and the Utah Tact. These items have been included <br />in this estimate. In response to the Division's first adequacy review for TR36, MCM updated the "Mine <br />Facilities" portion of section 2.05.3 of their permit as well as Map 25 and Table 56 which account for the <br />structures and facilities at the site. The Division updated Task 001 of the cost estimate based on this <br />revised information. <br />The previous cost estimate included the demolition of several structures that are not included in the <br />revised Mine Facilities portion of section 2.05.3 of the permit, revised Table 56 or depicted on revised <br />Map 25. These items are: <br />• Overland Conveyor; Portal 5 to Stockpile <br />• Elevated Conveyor; Portal 5 to Stockpile <br />• Wash Down Pad at No. 5 Mine <br />• Rotary Breaker <br />• Vent Fan and Housing <br />These items have been retained in the cost estimate and will need to be accounted for in the Mine <br />Facilities portion of section 2.05.3 of the permit, Table 56 and depicted on Map 25. Please revise these <br />documents accordingly. <br />OF c- 0 <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http: / /mining.state.co.us I <br />John W.
