XII EXHIBIT L - RECLAMATION COSTS <br />As described in Exhibit E - Reclamation Plan, and as shown on Figure F1, Reclamation <br />Plan Map, the proposed revised reclamation plan will consist of the following elements <br />and reclamation cost considerations (in general described counterclockwise from the <br />north end of the site): <br />1. Incorporation of the north part of the land bridge to Erger's Pond Pit (Mining <br />Phase 11) by simply wet mining from north to south and connecting the current <br />two halves of the City of Brighton's Ken Mitchell Lakes reservoir. <br />2. Wet mining of the southern portion of the land bridge adjacent to Bromley Lakes <br />Cell No. 2 and incorporation of that strip of land into Cell No. 2 open lakes and <br />shallow wetlands area. Reclamation grading of the east side of Cell No. 2 will be <br />done from the east from the already backfilled and reclaimed former fresh water <br />pond east of the land bridge in this area. <br />3. Removal of the transfer conveyor from Erger's Pond pit concurrent with mining <br />the land bridge from north to south as described in Items No. 1 and No. 2, above. <br />4. Creation of a water storage reservoir within 1) Bromley Lakes Cell No. 3, 2) <br />Ready Mixed Pit No. 1 (incorporated into this permit by this amendment), and 3) <br />the western portion of the new expansion area within the 100 year floodplain, <br />west of the relocated McCann Ditch. The proposed reservoir construction will <br />require approximately 9,023 LF of standard soil-bentonite slurry wall <br />construction. Assume one year of evaporative losses for 115 acre reservoir for <br />one year at 2.5 acre-feet per year, or 287.5 acre-feet. <br />5. Relocation of the McCanne Ditch, which will be done prior to mining. The Ditch <br />will be relocated to the new location shown by excavating it along the edge of the <br />100 year floodplain in native alluvial materials to preserve its hydraulic <br />characteristics as a gaining ditch. Approximately 2,118 LF of ditch relocation <br />will be necessary consisting of excavating a trapezoidal ditch cross section <br />approximately 25 ft wide at existing ground surface and 3 to 10 feet deep <br />depending upon final gradient and existing topography, with approximately 2:1 <br />50
