• <br />~~.•, United States Soil <br />Department of Conservation <br />Agriculture Service <br />Mr. Bill Gydesen <br />Operator/Owner, Lucky Strike Mine <br />229 County Road 11 <br />Gunnison, CO 81230 <br />Dear Bill (and to whom it may additionally concern), <br />February 20, 1982 <br />Upon on-site review of the mine area, and based upon your reclamation plans <br />as discussed, I see no problems of any significant nature in reclaiming the <br />site after mining is completed. The site was examined on Feb. 20. 1982 by <br />Jan Good, Engineering Aid, and myself. Although the review was made in mid- <br />winter with 6-12 inches of snow cover on the ground, sufficient exposed (wind- <br />blown) areas were found to determine dominant native vegetation and soil limi- <br />tations, upon wjsich to base reclamation recommendations. <br />The site is a dry mountain loam range site, with native vegetation character- <br />ized by the plant community described on form CO-RANGE-6 (attached). Soils <br />are gravelly to stony sandy loams, with characteristics and limitations as <br />described on the attached soil series description. Please refer to these two <br />attachments for any information regarding existing conditions. <br />Concerning reclamation recommendations, the area in question should be top- <br />soiled, if possible, to a minimum of 6 inches depth, with larger stones and <br />rock material segregated toward the bottom of the topsoil surface layer. Any <br />topsoil originally removed from the area for stockpiling should be reapplied <br />with a minimum of disturbance to the root reserves native to the soil. Shaping <br />and grading of the area should pr ode for reduced slopes and broad exposures <br />to the prevailing wind direction. yIn areas where steeper slopes are unavoidable, <br />contour furrowing or small basin terraces may e new y- - <br />place opsoi and seed. Straw mu c ing s ou als onsidered on such slopes <br />to help assure seeding establishment. ? ~ roL~ ogre <br />Upon reseeding, the seedbed should be,~elatively firm, friable, and rock and <br />weed-free as possible. A seed drill//urith depth bands, packer wheels or chains, <br />and grass/legume attachments or adaptability is preferred, so as to place the <br />seed at a consistent, optimum depth of approximately y.-y'z inch. Seed species <br />and seeding rate recommendations can be found on form CO-COIdS-6 (attached). <br />If seed is broadcast, seeding rates should be doubled (lbs./acre). <br />The area reseeded should be deferred from all livestock grazing for at least <br />two full growing seasons, or until a relatively good stand is established. <br />Fertilizer application during the first growing season of the established <br />plants, based upon soil test recommendations, should also be considered for <br />providing optimum growth conditions. <br />O The Sod Conservation Servwe SCS-AS-1 <br />U is an agency of the Ip_7g <br />Deparlm enl Or Agnc Wfure <br />
