M-1978-349 (Dick Casey Concrete Pit) <br />2009 Technical Revision <br />March 31, 2009 <br />Page 5 <br />Concurrent Reclamation <br />The possible use of inert fill from off-site is anticipated to augment backfill, subject to <br />Construction Materials Rule 3.1.5 (9). The plan is consistent with this Rule should it <br />be needed, though not requested at this time. The mining area will be reclaimed <br />concurrently. See Exhibit F for further information on reclamation. <br />Phasing Plan <br />The original Permit included three individual phases of approximately 19-20 acres in <br />each Phase. Phase 1 of the original plan, lying along the western boundary of the <br />M-1978-349 permit area, is mined-out and not a part of the current Technical <br />Revision. <br />In this Technical Revision, the final two original phases (Phases 2 and 3) have been <br />consolidated into one phase to be mined. The overall land area of the mining area, <br />as revised, that will be approximately 34.4 affected acres of land, is to be mined in <br />one phase as illustrated on the Exhibit C-2 map. <br />The current estimate for phasing of the operation is provided as follows: <br />Table D-1: Mining Phases <br />Phase Mined Estimated Duration Direction of <br /> Acreage of Mining Period Mining <br /> (years) <br />Present-day 34.4 From Present, Southwest <br />thru Life of 5 -10 years of to Northeast <br />Mine mining <br />5
