<br />Page 2 ~~~ <br />Mr. Thomas Schreiner <br />September 14, 2000 <br />6. It is estimated that the overburden will be used as follows: <br />a. 75,000 cubic yards to raise the elevation of the 9.5 acre pod 5 processing area, <br />b. silts will be used to fill the 7 acres of wetland benches to finish contours, <br />c. 465,000 cubic yards to backfill and grade the 15,156 lineaz feet of shoreline <br />d. The remainder of the overburden will be sold. <br />The applicant will obtain approval of all required permits from the Office of the State <br />Engineer prior [o exposing groundwater and/or dewatering at the Milliken Site. <br />The proposed ponds will be sealed with a slurry trench. The location of the trench is <br />indicated on the mining plan. We have included a representative cross section of the slurry <br />trench, design standards and a narrative of the construction methods to be used to install the <br />slurry trench. <br />EXHIBIT E -RECLAMATION PLAN <br />9. The operator estimates the volume of topsoil that will be maintained on-site for reclamation <br />[o be 400,000 tons. The acreage of top soiled areas that will be revegetated with a grass <br />seed mix is estimated to be approximately eight acres. <br />10. The "Shoreline Reclamation Revegeta[ion" cross-section on the reclamation plan shows the <br />slope will vary with a 4:1 or shallower slope for the wetland benches. <br />11. The applicant anticipates the plant life on the wetland benches will be volunteer growth. <br />We estimate a contingent revegetation plan will cost approximately $450/acre. The <br />contingent wetland seed mix would include: <br />COMMON NAME SCIENTIFIC NAME VARIETY % OF <br />MIX PLS <br />APPLICATIO <br />N RATE <br />(Ibs/acre) <br />prairie cordgrass Spartina pectinate native 25 4.0 <br />western wheatgrass Pascopyrum smithii Arriba, 20 3.2 <br />alkali sacaton Sporobolus airoides Barton 10 1.6 <br />fowl bluegrass Poa palustris 15 2.4 <br />managrass Glycera striate 10 1.6 <br />american sloughgrass Beckmannia 10 1.6 <br />marsh sunflower syzigachne 5 0.7 <br />blue vervain Helianthus nuttallii 5 0.8 <br /> Verbena hastata <br />TOTAL (Ibs/acre) 15.9 <br />
