VI. Backfilling and Grading <br />A. The Division proposes to approve the applicant's plan for disposal of acid-forming or <br />toxic materials in a manner designed to prevent contamination of ground or surface <br />waters (4.143(1)(a)). <br />B. Since this is a truck and shovel operation, backfilling and grading of the overburden <br />occurs simultaneous with overburden removal. The generation of excess overburden <br />is not anticipated. <br />VII. Reve etg ation <br />A. The Division proposes to approve the use of introduced species in the reclamation seed <br />mix. The applicant has submitted information which shows that the introduced <br />species aze desirable and necessary to achieve the approved post-mining land use, and <br />aze not poisonous or noxious (4.15.2). <br />B.

At the request of landowners whose land has been mined through, replacemnt of the <br />few small apple orchazds should not be replacxed, but instead, made into irrigated or <br />non-irrigated pasture. <br />D. Methods to measure herbaceous cover and production, species diversity, and woody <br />plant density aze discussed in the permit application. These techniques include: <br />New Horizon Mine 1 <br />Cover -Point intercept along a randomly located line transect or ocular estimates <br />in randomly located sample quadrats. <br />2. Production -Clipping of 1 meter squazed plots, oven drying and weighing. <br />3. Species diversity -Qualitative comparisons using cover and frequency values. <br />4. Woody plan[ density -Counting within randomly located belt [ransects. <br />25 <br />
