M-1978-349 (Dick Casey Concrete Pit) <br />2009 Technical Revision <br />March 31, 2009 <br />Page 6 <br />Exhibit E - Reclamation Plan <br />The original 112c Permit anticipates that approximately 29 acres of the 34.4 acres <br />identified in this Technical Revision will become ponds. By consolidating mining <br />into a single excavation, shoreline side slopes will be reduced and the normal water <br />elevation will be uniform. The overall water surface area will be comparable to <br />existing plans due to a lower, uniform water surface and potential fill at the easterly <br />end of the excavated area. <br />Inert backfill, upon notice and approval according to Construction Materials Rule <br />3.1.5 (9), may be used to selectively raise the pit floor at the time of reclamation. All <br />areas of fill will be appropriately vegetated as called for in this Reclamation Plan. <br />At time of reclamation release, the affected area of 34.4 acres will be seeded (e.g., <br />the portion thereof not subject to indundation, see Exhibit F), along with revegetation <br />of vacated processing areas above grade. See revised Exhibit F for a new seeding <br />plan, consistent with current practices and preferred cover for the region. This plan <br />is based on current practice and advice from the NRCS. For additional information <br />regarding reclamation, Exhibit E of the original 112c Permit remains in effect. <br />Exhibit F - Reclamation Plan Map <br />The Reclamation Map has been updated to show slopes, open water, and <br />revegetation revised as a result of modifications to Exhibits C, D, and E, as <br />described above. Revised Exhibit F also includes a typical side slope detail and <br />updated seeding chart. Please see the attached plan drawing. <br />Exhibit L - Reclamation Costs <br />The applicant is requesting that 34.4 acres may be disturbed at one time, consistent <br />with one-phase mining. The cost estimate below covers all areas of the M-1978-349 <br />permit and is based on the maximum amount of disturbance that is planned for this <br />6
