Kerr (Marr) Mine - Phase III Final Bond Release Request - Permit # C -60 -006 contour furrows, drainage ditches and roads, approved grazing practice, weed control, vegetation monitoring and water analysis during the liability period. (2). A map showing the revegetated areas, each year's sampling locations, and reference area(s) if used: All of the areas seeded at the mine site, and the dates of seeding, are shown on the accompanying Phase 3 Bond Release Map. Sample observation locations, as transect locations and the Reference Areas (2 Reference Areas) are shown in detail on maps included with the Kerr Coal Company 2005 and 2006 Revegetation Monitoring Reports conducted by I.M.E. and are on file at the Division. (3). Documentation that revegetation success criteria as required by Rule 4.15.8 have been achieved for the last two consecutive years: Documentation that the revegetation success criteria have been met for the last two consecutive years are shown in summary on attached Table 5. Vegetation species diversification concerns pertaining to the unreleased areas referenced are addressed in Technical Revision No.25 (TR -25) on file with the Division. Complete copies of the vegetation sampling reports for the last two years of the liability period are on file at the Division (see Kerr Coal Company 2005 and 2006 Revegetation Monitoring Reports). (4). A discussion and documentation that the approved post- mining land uses have been achieved: The Division approved the post- mining land use intended for rangeland and wildlife which was the original land use designation at the mine site and Loadout. Livestock grazing on the reclaimed areas at the mine site has occurred periodically following the contemporaneous reclaimed areas as vegetative forage became available. Prior to grazing periods, the volume of forage was determined by the local County Extension Offices (Route and Jackson Counties) and the stocking rate, or animal units per month (AUM's) to be used were determined based on 1,000 pounds of air dried forage as being equivalent to one AUM. This data was submitted to the Division in the form of a Grazing Plan Request (Minor Revision Request) and after the Division's approval, the Plans were initiated. The practice was to graze a large number of animals for a short period of time through the site. This was accomplished by utilizing the large herd of cattle on the neighboring cattle ranch adjacent to the mine. Given the number of cattle available during the season, the time element was calculated for the AUM's which was determined by the County Extension Agents. Additionally, large herds of Elk have grazed through the site for short periods during the winter months. In terms of future use of the land for rangeland and wildlife, access to the reclaimed areas for livestock grazing is facilitated by rolling terrain and adjacent pasture areas. The reclaimed areas are bounded by fences, and water is available at the permanent ponds at the site. The remaining sediment ponds, roads, shop building, and permanent ditches will all remain after reclamation as approved for permanent status. These structures will effectively enhance and support the approved postmining land use. 5
