<br />The company states the control areas were selected for each major vegetation <br />type disturbed, based on species composition, cover and productivity, and <br />slope and aspect. The applicant has not demonstrated that the control areas <br />are representative, resulting is three stipulations added to mitigate expected ' <br />problems (please see State Stlpulatiaa lib, 9, and 10 for specifics). <br />The company proposes to use the control areas as the revegetation success <br />standard for herbaceous cover and production. Species diversity and woody <br />plant density standards will be developed following completion of the <br />vegetation sampling. The diversity standard will be based on species <br />composition and life form importance for herbaceous vegetation and species <br />composition as determined from relative density for shrubs. <br />Upon cessation of mining, all areas will be regraded, topsoiled, then <br />revegetated. Seeding for revegetation will be done in the Pali. Revegetation <br />at best will be difficult because of low precipitation and sal'_ne sad sodic <br />soils. However, under intensive management, the company should be able to <br />meet the required revegetation success criteria. <br />Fish and Wildlife <br />The compa~ consulted Division of Wildlife and Bureau of Land Management <br />wildlife auehoricies regarding impacts of mining operations on wildlife <br />species. <br />The Whittaker Flats area Sa Che northwestern por2lon of the permit area <br />provides winter range for a portion of the Roan Creek mule deer herd. The <br />western third of the permit area makes a small part of the Little Bookcliffs <br />Wild Horse Area. Neither of these populations are expected co be <br />significantly impacted by mining since surface disturbing activities are yell <br />removed their ranges. <br />The cam*on walls in the general vicinity of the operation provides potential <br />nesting habitat fot raptors. The surface facilities are located along the <br />river at the base of the canyon and are removed by at least 300 yards from <br />potential nesting areas. The presence of Interstate i0 through Debeque Canyon <br />may already Smpacted raptors to some degree. No additional impacts are <br />anticipated with respect to raptor nesting, since there are no additional <br />plans to disturb any more areas. <br />Riparian habitat along the Colorado River in the permit area provides Heating <br />cover for `fallard Ducks and Canada Cease. The river is used by numerous <br />waterfowl species during spring and fall migrations, and during the winter. <br />The river itself is c'_assed as a warm water fishery and may support <br />populations of four threatened and endanged fish: the Colorado Squavfish, the <br />Razorback Sucker, the Humpback Chub, and Boneytail Chub. <br />The compar.;• indicates that, "in planning specific reclamation activities, <br />special note will be taken toward enhancing wildlife habitat". The vildli`e <br />habitat with the greatest potential for being impacted Ss the riparian zone <br />adjacent to the river, used by water_`ov1. The plan does not soecifically <br />address protection or reestablishment of this habitat sad is so stipulated <br />(see State stipulations) <br />-'_3- <br /> <br />
