Mr. Jared Ebert, DRMS <br />Re: RN6 Adequacy Review No. 1 Response <br />Page 4 <br />Trapper Response: The pages and maps requested have been updated and are attached. There were no <br />updates necessary for page 3 -15c. <br />Other Maps <br />10. Please make any necessary updates to the following maps: M12; Postmining Topography Maps, M47a; <br />Utility Waste Disposal Plan and M09; haul roads. <br />Trapper Response: The maps requested have been updated and are attached. <br />Bond Amount <br />11. For Task 093, the volume of topsoil used for the estimate was derived from Table 1.4 -9 in the permit. <br />However, during the Phase II bond release SL12, the amount of bond was reduced to account for the <br />acreage of F -Pit contained in the release. Upon further review, the volume of material used for SL12 was <br />greater than the total volume estimate for the entire F -Pit area in Table 1.4 -9. Given this, there appears to <br />be a discrepancy in the volume estimated to spread topsoil on the remaining F -Pil area not granted Phase 11 <br />bond release. As indicated above, section 1.4 of the permit will need to be updated and the volume of <br />material for F Pit will need to be clarified <br />12. For Task 101, there appears to be a discrepancy for the acreage accounted for F -Pit. During Permit <br />Renewal No. 5 (RN5), the acreage accorded to F -Pit for revegetation was 486 acres. However during the <br />PR6 it appears this acreage was reduced to 55.8 acres. It is unclear why the acres were reduced to the PR6 <br />amount. The PR6 acreage is consistent with Table 1.4 -10 in the permit. Since RN5, Trapper was granted <br />Phase III bond release on 40.1 acres of the F -Pit area. Given this, the Division used the RN5 F -Pit acreage <br />minus the SL 13 F -Pit acreage for the total area to be revegetated for F -Pit for the updated cost estimate <br />(445.9 acres). This acreage will need to be clarified. <br />Trapper Response: Trapper will respond to comments 11 and 12 above as part of the overall bond estimate <br />in the forthcoming submittal of the PR -07 document. <br />Please contact me if you have any questions or concerns with the attached information. <br />Forrest Luke <br />Environmental Manager <br />FVL <br />[RN06Response l .doc1 <br />Encl <br />c File 109.2 3.4, w/o enc <br />
