Rule 2.05.4 -- Reclamation Plan 1) The Reclamation Map (Map 29) is proposed to be revised. The revised map does not include pertinent information that is on the currently approved Map 29. For example, on portions of the affected area, the map does not include; cross sections, adequate post mine contours, post mine land use designations and dates of disturbance. Either add the currently approved information to the revised map or keep the currently approved map and add the proposed revised map to the permit under a different title and designation (Map 29a for example). 2) On the currently approved Reclamation Plan Map; Map 29 it is difficult to determine which areas will be reclaimed to the following post mine land uses: RangelandlWildlife, Cropland and Pasture Land. On the revised map discussed on the previous item, clearly delineate which portions of the affected area will be reclaimed to the designated post mine land use. 3) Revised Page 2.05 -31.2 discusses reclamation of the Utah Tract. The currently approved narrative for this section discusses the post -mine land use and seed mixture to be used for this area (rangelandlwildlife) and discusses the mulching rate and crimping requirement. The proposed revised page leaves out this information and simply indicates the MCM has applied for a Phase 1 and 2 bond release for these parcels and plans to sample the areas for final Phase 3 bond release in the future. Please revise this page to include the reclamation information. a. MCM Response to items 2 through 3: In order to provide all relevant information, MCM will retain the existing Reclamation Plan Map, and add the updated Reclamation Map as Map 29a. As appropriate, text references have been modified to reference both maps. Page 2.05 -31.2 has been revised to include the previously provided information, and the revised page is included with these responses. b. DRMS Response: i. Item #1 is resolved. ii. Item #2 was not addressed. This item remains outstanding and will need to be addressed prior to the approval of TR36 and RN6. Respo: Map 29 has been reviewed and compared with the Pre - Mining Land Use Map (Map 3). Postmining land -use designations have been added to Map 29 which generally reflect restoration of mine disturbance areas to the pre - mining use. It should be noted. however., that there may be some, mbi u.t in the pre- mining use designations, and the designated postses refle nticipated future use for the disturbed and surroundireas W. Item #3 is resolved. Rule 2.05.6 — Mitigation Of the Impacts of Mining Operations 1) On revised page 2.05 -38; MCM provides the Theim equation. There are two "R" variables in the equation. The variable for the radius of a point on cone of depression should be a lower case "r ". Please correct this variable and submit a revised page. a. MCM Response: Page 2.05 -38 has been revised to correct the noted typo, and the revised page is included with these responses. b. DRMS Response: This item is resolved.
