The production standards are based on the lower confidence limit of the historic <br />production means on each range site, utilizing data from 1979-1985. The standards are as <br />follows: <br /> gms/m2 lbs/acre <br />Range site A 62.39 556.14 <br />Range site B 42.49 378.76 <br />Range site C 47.46 423.06 <br />Seed mixes and revegetation practices are designed to meet diversity standards set forth <br />in the permit for herbaceous species and woody shrub species. These standards were <br />revised through TR-71, approved in 1998. <br />The diversity standard for herbaceous species is based on pre-mining historical data. The <br />standard is: <br />1) At least five principal species including a minimum of four cool season perennial <br />grasses and a minimum of one perennial forb. <br />2) Each principal species shall contribute no less than 3.0% relative cover. <br />3) No single species shall contribute in excess of 50% relative cover. <br />4) No four species in combination shall exceed 80% relative cover. <br />The applicant will reestablish shrubs on Range Sites A and B by including various native <br />shrubs in the seed mixes and by transplanting mature woody shrub clumps. A minimum <br />of 250 mature shrub pads will be transplanted in each clump. The clumps are <br />approximately 1,400 apart. The shrub density standard on Range Sites A and B is a <br />minimum 400 live stems per acre and a minimum 50% survival of pads within each <br />clump. There is no shrub density standard for Range Site C. (4.15.7(1)). <br />XII. Post-mining Land Use <br />The post-mining land use is discussed under Section 4.2 of Vol. IV of the permit application. <br />1. Cropland, rangeland and wildlife habitat are the currently approved post-mining land <br />uses. Recreational uses such as picnicking and hiking during the summer months as well <br />as cross-country skiing and snowmobiling during the winter months would be compatible <br />with the reclamation and the surrounding areas. Industrial use of the facilities area is <br />possible but these facilities are not currently approved as permanent. The Division has <br />approved the alternative post-mining land uses of recreation (mine-wide) and industrial <br />development of the facilities area only. These alternate land uses must be considered in <br />terms of their compatibility with wildlife and domestic livestock use. The land-use meets <br />the criteria of Rule 4.16.3. <br />Trapper Mine 28 July 25, 2008 <br />!I
