C) <br />RPM, Inc. <br />Rule 6.4.6: Exhibit _F- Reclamation_ Platt HO <br />6. The reclamation plan map depicts the physical appearance of the area of the affected <br />land and the proposed topography of the area with contour lines of sufficient detail to <br />portray the direction and rate of slope of the reclaimed land for the AM01 area. The <br />post mine slopes depicted on the map for the north end and east ends o mining Phases <br />1, 2, 4 and S show the post mine slopes to rangy from a 2.2 to 2.5:1 horizontal to <br />vertical ratio slopes. The reclamation plan narrative indicates that most of the mine <br />slopes should be graded to a 3:1 horizontal to vertical ratio. Please revise the <br />reclamation contours on the map to reflect that the post mine slopes will be graded to a <br />3:1 horizontal to vertical ratio. <br />Response: <br />Based on our conversations with the DRMS and later confirmed via email, the DRMS <br />determined the existing post mining contours on the Reclamation Plan Map are <br />adequate. We agreed to add a note to the Reclamation Plan Map that the post mining <br />contours are approximations of the post mining land configuration and that all final <br />reclaimed slope will be 3H:1 V or less. We also agreed to place on the Reclamation <br />Plan Map that the post mining land use is rangeland. A new Reclamation Plan Map <br />and page 44 are attached to this document. <br />7. In accordance with Rule 6.4.6(b) the reclamation plan map must portray the <br />proposed final land use for each portion of the affected area. Since the applicant <br />proposes to reclaim the site to rangeland, please add a notation that the entire <br />affected area will be reclaimed to rangeland <br />Response: <br />Please see the response to item 6. <br />8. The proposed permit boundary of the area is not clear. Similar to item #1 above, <br />please revise the map to clearly show what the amended permit boundary will be. <br />Response: <br />The requested changes have been made to the Reclamation Plan Map. A new <br />Reclamation Plan Map and page 44 are attached to this document. <br />ramyxxmv�t�.tsi1 i 1 <br />The applicant submitted a reclamation cost for the Phase 1 mining area. The Division <br />conducted a pre- operation inspection of the site on March 30, 2017 and will be conducting <br />a cost estimate for the current disturbance at the site and will be initiating a surety increase <br />revision. Given this and the current proposed phased mining plan, the Division conducted <br />a reclamation cost estimate for AM01 only to reclaim the Phase 1 mining area. This <br />estimate is enclosed for your review. The Division's AM01 estimate does not include <br />equipment mobilization costs as these costs will be included in the estimate the Division <br />conducts for the forthcoming surety increase revision. On approval of AM01, the operator <br />will need to submit and receive approval of the additional bond for the Phase I mine area <br />prior to initiating mining and reclamation operations within the Phase I area.
