Exhibit Page 18 <br />backfill, especially on ridges dividing the ponds, or to create permanent berms as discussed above to tie in with <br />landscaping of the ponds. There are not expected to be any heavily textured backfill slopes which could have a <br />potential for instability of topsoil placed on them. Topsoil existing on site appears to be of adequate quality and <br />quantity (after screening out oversize) to allow for reclamation to pastureland. If screening fines are required to <br />be used as replacement for topsoil, amendments shall be added as indicated by soil testing. Any vegetative <br />piles will be removed during reclamation. <br />Revegetation (3.1.10.) <br />Final reclamation will include establishment of aself-sustaining vegetative community of pasture grasses and <br />plants around the ponds. During reclamation, weed control methods as approved by Conservation District and <br />County officials will be used on all affected land to prevent/control weed infestation. Reclamation will be <br />deemed to have been accomplished when vegetative cover is at least equal in extent of cover to the natural <br />vegetation of the surrounding area, and erosionlsedimentation is equal to or less than that of the original <br />conditions of the site with increased slopes taken into account. Final approval of reclamation will be granted by <br />the Colorado Department of Natural Resources after reporting and inspection. Original vegetation cover is <br />documented by photography in 2000 on the site. [Selected areas (shown on Maps, Exhibit F) will be planted <br />with shrubs, and selected areas along the shore of the ponds will be planted with willows and other pond <br />vegetation as recommended by NRCS, to meet county requirements only.] <br />The seed mixes and methods of seeding, fertilization, and weed control to be used (Exhibit J) have been <br />approved by the Natural Resources Conservation Service, and Iccal Conservation District, and were <br />recommended by the District Conservationist. The large buffer area around the entire site (not disturbed by <br />mining) will provide a source of seed for natural propagation of species native to the area which are not included <br />in the seed mix. However, this buffer zone and adjacent lands which have been impacted by overgrazing, as <br />well as portions of the site not already mined, will be a potential source of weeds and will require careful <br />management in cooperation with the Montezuma County Weed and Pest Control agency and the landowner. <br />As a result, the District Conservationist recommends certain practices (described in Exhibit J) to rehabilitate the <br />land prior to mining, as well as land outside the permit boundary which serves as a buffer zone. (It is intended to <br />work with the landowner to implement those recommendations but that work is outside the scope of this <br />application and is provided only for information.) <br />TOPSOIL, SPOIL, AND REVEGETATION (6.4.5.(2)d.) <br />As discussed above, topsoil will be removed from the pit and segregated in stockpiles. Stockpile areas wilt be <br />reclaimed and revegetated in the same way as other mined areas. Where soil was left at the time of construction <br />(because soil was placed in the stockpile), the areas will be chiseled or ripped (scarified) prior to replacement of <br />topsoil and seeding. Although not planned, if there are stockpile areas where soil was removed to stockpile <br />materials other than soil or excess fines, these will have the soil replaced to the original depth or 12 inches, <br />whichever is less, and then seeded. Stockpiles not on the perimeter of the permit area (which will predominantly <br />contain screening fines and other spoil) will generally be left in place (see Exhibit D), with backfilling and placement <br />of topsoil above the water level on top of the stockpiled material. As discussed above, revegetation will be done <br />around the ponds with species, methods, rates, availability and scheduling as discussed in Exhibit J. <br />Exhibit E-2a is across-section of the entire pit 200 feet north of the section line, showing a profile of the surface <br />before and after mining, and after reclamation. Exhibit E-2b is a detail cross-section of the western portion of E-2a, <br />showing slope stability, lines of sight, and post-reclamation slopes. <br />Map F-1 shows phases of reclamation. Map F-2 in Exhibit F show planned, approximate contours and pond water <br />surface elevations after mining and reclamation, as well as current and post-reclamation floodplain boundaries <br />(based on FEMA/USACE baseline flood elevations). Water level in the ponds will be controlled by use of inlet <br />controls on each pond (drop-inlet pipe spillway on shore of pond), with discharge into a lower pond and ultimately <br />into the pre-existing drainage pipe to the Dolores River. <br />Four States Aggregates, LLC 15 MAR 2001 <br />Application for Permit: Line Camp Pit M-2001-001 FSA-LCP-D2-001 <br />
