DRMS found the seed mix adjustments acceptable. 2. Methods to measure species diversity, woody plant density, herbaceous cover and production are discussed in permit section 4.4.1, Volume IV. Seed mixes and revegetation practices are designed to meet diversity standards set forth in the permit. The applicant will reestablish shrubs on Range Sites A and B by including various native shrubs in the seed mixes and by transplanting mature woody shrub clumps. There is no shrub density standard for Range Site C.(4.15.7(1)). XII. Post-minim Land Use Post-mining land use is discussed under Section 4.2, Vol. IV of the permit application. Cropland, rangeland and wildlife habitat are currently approved post-mining land uses. These land uses meet the criteria of Rule 4.16.3. XHI.

Concurrent Surface and Underground Minim No specific approvals are granted to the applicant under this section. XVII—Auger Mining—Rule 4.23 Auger or"Highwall mining" is planned in the I, J, L and N pits. Subsidence is not anticipated with any highwall mining activities at the site. Trapper is not currently aware of any abandoned or active underground mine workings in any of the pertinent coal seams in the proposed highwall mining areas. In the event abandoned or active underground mining operations are identified, no highwall mining will be conducted within 500 feet of previous workings in the applicable seams. Trapper is also not aware of any dwellings,buildings, tanks,impoundments or utilities overlying areas planned for highwall mining. Design criteria established by Agapito Associates Inc. will be utilized to ensure long-term stability of highwalls and mining areas based on seam and overburden thickness. Access to highwall miner entries will be blocked or buried within 30 days following coal extraction.
