Page 23 of 27 <br /> Exhibit 14, Supplemental Vegetation Information. Vegetation communities are shown on Map 20 - <br /> Vegetation Map. Section 2.05 of the permit application describes the revegetation methodology and <br /> revegetation standards for each type of disturbed area. The Williams Fork Strip Pit revegetation plans <br /> and revegetation success criteria are given in Exhibit 24,Williams Fork Strip Pit Reclamation Plan. The <br /> Reclamation Plan Map (Map 29a)indicates the planned post-mine uses (vegetation types)and the <br /> reference areas for the reclaimed areas. <br /> Roughly one-third of the permit area is covered by croplands. MCM has divided the croplands into two <br /> categories: 1) irrigated hayfields in the Williams Fork River bottom areas, and 2)dryland wheat,found <br /> on cleared hillsides which were once sage-dominated. Productivity data is provided for the irrigated <br /> hayfields on Table 69 of the permit application. Wheat production is given in Table 70. <br /> A. The Division has previously approved the use of four introduced species in the reclamation seed mix <br /> based on information submitted by the permittee demonstrating that the introduced species are desirable <br /> and necessary to achieve the approved post-mining land use and are not poisonous or noxious. These <br /> species include Pubescent wheatgrass,Hard fescue,Birdsfoot trefoil, and Cicer milkvetch(4.15.2). <br /> B. The Division has previously approved the use of straw mulch as a means to meet soil stabilization <br /> requirements. Straw will be applied at a rate of two tons per acre and secured by crimping or tacking <br /> (4.15.4). <br /> IX. Protection of Fish,Wildlife, and Related Environmental Values <br /> Wildlife information is found in the permit application in Sections 2.04 and 2.05,Map No. 21, Exhibit <br /> No. 15 and Exhibit 15A and Table 41. All post-mining areas are to be reclaimed to pre-mining land uses, <br /> including wildlife habitat. The applicant has selected appropriate plant species and distributions to <br /> benefit fish and wildlife in accordance with Rule 4.18(5)(1). <br /> Pursuant to the finding required by Rule 2.07.6(2)(n), and on the basis of available information,the <br /> Division finds the current reclamation operation at the site will not affect the continued existence of the <br /> previously discussed endangered or threatened species,or result in the destruction or adverse modification <br /> of their critical habitat. Due to the potential for Bald eagles to have encounters with power lines,there <br /> exists a"may affect,but not likely to adversely affect"finding for Bald eagles. This finding still applies. <br /> X. Subsidence <br /> Subsidence was last detected in the July-December 1995 monitoring period, during the last period of <br /> active mining. Section 2.05 of the permit application explains that subsidence monitoring for the No. 5 <br /> Mine was discontinued in November 1988 following completion of mining in the No. 5 Mine. <br /> Subsidence monitoring for the No. 6 Mine was suspended in October 1997. <br /> 1. The Division has previously found the permittee's subsidence control plan complies with Rule <br /> 2.05.6(6) and the permittee has committed to adopt all measures in order to reduce the likelihood of <br /> subsidence,prevent material damage, and mitigate the effects. The Division has previously approved the <br /> Williams Fork Mines Prepared by: R ReiRey M.S. GISP <br /> C1981044 December 2023 <br />
