AREA AT THE TRAPPER MINE. MONITORING FOR THIS PURPOSE SHALL CONSIST OF A <br />CONTOUR MAP (CONTOUR INTERVAL NOT TO EXCEED 5 FEET) PRODUCED FROM AN <br />ANNUAL SURVEY UTILIZING FIELD OR AERIAL PHOTOGRAMMETRIC TECHNIQUES <br />ACCEPTABLE TO THE DIVISION. THE POST-MINING TOPOGRAPHIC MAPS SHALL BE <br />SUBMITTED TO THE DIVISION FOR REVIEW AND APPROVAL ON AN ANNUAL BASIS, <br />COMMENCING IN JANUARY 1984. <br />Stipulation No. 10 was terminated on November 6, 2000 with a revision to the <br />permit. TMI provides a contour map of each year's backfilled and graded areas <br />with each Annual Reclamation Report. <br />XI. Reve etg ation <br />The Division previously approved Trapper's revegetation plan as set forth in Section 3.6, <br />Vol. III of the permit application. The plan is summarized below. <br />The applicant will use introduced species in the reclamation seed mix. The <br />applicant has submitted information which shows that the introduced species are <br />desirable and necessary to achieve the approved post-mining land use, and are not <br />poisonous or noxious. (4.15.2). In conjunction with Trapper's years of reclamation <br />experience, Trapper has reduced the number of introduced species in their seed <br />mixes. The seed mix presented in the 2006 Annual Report for both the Range Sites <br />A & B reduced the more aggressive rhizomatous wheatgrass species while the <br />amount of Beardless bluebunch wheatgrass was increased and Indian ricegrass was <br />added to the seed mix. The seed mix adjustment was found to be acceptable. <br />2. Methods to measure herbaceous cover and production, species diversity, and woody <br />plant density are discussed in section 4.4.1 of Volume IV of the permit application. <br />The cover standards are based on cover which will keep soil loss, due to rill and <br />sheet erosion, to less than 4 tons per acre per year based on the application of the <br />Universal Soil Loss Equation. These standards call for a 52% effective cover on <br />Range Sites A and B and 43.6 % effective cover on Range Site C. The litter <br />component included must be natural. <br />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 <br />are as 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 />Trapper Mine 33 September 21, 2009
