CHAPTERTWO Proposed Action and Atternatiues ' <br />2.2.7.5 Revegetation , <br />Piceance Sife , <br />Assuming that initiation of reclamation of a particulaz mining panel would only ~~ccur after <br />neazly all of the solution mining wells in that particulaz panel have been retired, :seedbed <br />prepazation and reseeding would generally occur during the first fall after the muting panel ' <br />becomes inactive. <br />In all locations where excavations or grading would occur, existing topsoil would be stripped to a <br />maximum depth of 6 to 8 inches and stockpiled adjacent to the excavations for ltder use in <br />reclamation. During reclamation, disturbed azeas would be graded, the salvaged topsoil evenly <br />replaced, and the surface seeded. <br />Seedbeds would be prepazed by disking following the natural contours, and seed would generally <br />be applied by drilling. In azeas that cannot be seeded by drilling, seed would be broadcast at <br />double the specified seeding rate and harrowed into the soil. Additional seed applications may <br />be required to accommodate specific site conditions or if initial seed germination fails. <br />Disturbed azeas would be reseeded with a seed mixture approved by the BLM. VV}tere possible, <br />native seed mixtures most suitable to a specific range site would be used instead of the standard ' <br />seed mixtures. Seed that is certified and free of noxious weeds would be used whenever <br />available. Seeding would occur in the fall after September 1 but before prolonged ground frost. , <br />In consultation with the BLM and CDMG, American Soda would establish performance <br />standazds, such as percent cover and species distribution, by which to assess revc~getation <br />success, particularly in the lazge well field reclamation azeas. In the event of seeding failure or , <br />increased erosion, additional work may be tamed out as considered necessary by the BLM. <br />Pipeline Corridor <br />Revegetation of the pipeline corridor would be initiated during the first fall following pipeline <br />installation. ' <br />Seedbed prepazation would include scarifying or tilling soils to enhance revegetidion success. <br />Seeding depth would reflect requirements of the specific seed mixtures. As above, disturbed ' <br />areas would be reseeded with a seed mixture approved by the BLM. Certified sexed that is free of <br />noxious weeds would be used. Either drill or broadcast seeding would be used for seed <br />application, based on site-specific conditions. Drill seeding would be employed on fairly level ' <br />areas where coarse fragment content allows drilling operations. Seeding would ~~ccur in the fall <br />after September 1 but before prolonged ground frost. <br /> , <br />Parachute Site <br />Because no mining would occur at the Parachute Site, revegetation activities would be associated ' <br />primarily with reclamation of surface facilities at the end of the Yankee Gulch Project as <br />described in Section 2.2.73. Reclamation and revegetation of these surface facilities would be <br />consistent with applicable requirements in effect at the time ' <br />. <br />2-28 <br />
