(Colowyo) PAP, the Division has the following comment: <br />1. The Division has performed an updated reclamation cost estimate (RCE) to reclaim the disturbance <br />associated with the Collom Haul Road Cumulative Bond Schedule (see Exhibit 13C). The total value <br />of this estimate is $4,950,600.86 (see attached cost estimate). This estimate includes the revisions to <br />Exhibit 13C associated with the approved TR -108, TR -113 and TR -115 as well as updates the Collom <br />Haul Road Crossing (see task 002 of the attached cost estimate). 1t should be noted that this value is <br />an update to the already approved RCE and not a full liability increase of $4,950,600.86. The <br />Division's cost estimate is consistent with previous cost estimates approved by both the Division and <br />Colowyo. The Division respectfully requests a response from Colowyo with any questions regarding <br />the cost estimate or an acceptance of the Division's estimate. <br />2. While the Collom Haul Road Crossing is currently bonded as part of Exhibit 13C, there currently does <br />not exist any discussion within the exhibit about the crossing. Please update Exhibit 13C to include <br />discussions of the Collom Haul Road Crossing within the cumulative bond schedule. <br />1313 Sherman Street, Room 215, Denver, C080203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br />John W.
