~r:._ ' ~ <br />- 4 - <br />.aiL 9 ;;, ; ~. <br />annual excavation rate oC 1 million Cons weulc' extend thq,,.eper~tion <br />L'hrouglt the ycnr 7005. 'fhe reclamation will progress accbrdi-ugly <br />with the establishment of the benchcn per the minin}; plan and <br />Ci.metahlc. A ~oritCen explanation tlicrcof is as follo ws: <br />1975-80 - licnches 6705 and 6625 between stations 0+00 to 5+00, <br />6945, 6865 and 6785 between stations 3+00 to ]. 5i-00 on the north <br />side, 7025 and remaining; portions of 6945 and 6865 between stations <br />15+00 to 20+00 and 6865 and 6785 on the south side. <br />1980-85 - Remaining portion of bench 6785 on the north side between <br />stations 13+00 to 18+00, 6705 between stations 5+00 to 14+00 on <br />the north side and 6705 on the south side of the quarry. <br />1985-90 - Remaining portion of benrh 6705 between stations 11+00 <br />to 17+00, and 6625 on the north and south sides of the quarry. <br />1990-95 - Bench 6545 <br />:.995-2000 - Bench 6465 <br />2000-2005 - Benches 6385, 6305 and 6225. <br />The 40' level horizontal portion of the benches coill be covered <br />with quarry fines and in some cases stripping. 'Phese soils will <br />be supplemented with an organic fertilizer C-o support the <br />revegetati.on program, For more pertinent details on reclamation <br />refer to the Thorne Ecological Report of 1975 and the vegetation <br />section of. the site plan, Reclaimed areas and their vegetation <br />will be maintained at least 3 years to assure their succe:~s, <br />Maintenance will include halting soil erosion, if any, noel reseeding <br />or planting to assure a vegetative cover, <br />P7.ans for drainage of the area during and after operation are <br />provided in the drainage report by Leonard Rice Consulting Water <br />Engineers of April 1975 and presented herewith as a part of this <br />application, A summarization would be as folloc.s: Drainage of <br />Strain Gulch from outside the operational area is passed through <br />the operations via a large underground concrete conduit, Nearly <br />all the drainages from within, are directed to a detention basin <br />for settling before being allowed to pass Chrough the underground <br />conduit. The conduit and detention basins are of such size to <br />accommodate the 100 year flood, Testing the waters of. Strain Gulch <br />during the previous years of operation revealed no pollution and <br />that its quality remains good, Refer to r_lte Thorne Ecological <br />Institute's Reports of 1972 and 1975, <br />
