tongue, and cheatgrass was also observed. In general, erosion is not a problem in these parcels, but a rill approximately one foot deep was observed near the south end of the F Pit reclamation. The Division did not request that these issues found during the inspection be addressed, other than ongoing weed control and monitoring of the rill. A follow -up inspection was not required. Permitted topsoil depth replacement on rangeland is 12 inches plus or minus 2 inches (permit page 4 -256). TMI verifies topsoil replacement thickness by scraper load counts. A load count for each reclamation parcel is included in the bond release application. Topsoil verification was conducted during monthly inspections as documented in DRMS inspection reports dated October 11, 2005, October 12, 2005, and the bond release inspection of August 30, 2011. All parcel areas verified by the Division were within the permitted topsoil replacement thickness. The following table summarizes the bond release parcels included in the application and shown on the "SL -12 Phase II Bond Release Area Delineation" maps (Map 1, Sheets 1 through 3). Bond Release Parcel Acres Topsoil replacement depths (inches) F -AB -05 73.0 17.0, 14.0 F -AB -06 52.3 16.3, 15.0 Z -AB -05 38.7 14.0, 19.0 Z -AB -06 1.5 11.2, 11.0 Total 165.5 Bond Release Blocks Delineation The reclaimed parcels are compared to three different range standards based on elevation: range site C, range site B, and range site A. Range site C standards apply to elevations below 6700 feet, range site B standards apply to elevations above 6700 feet and below 7200 feet, and range site A standards apply to elevations greater than 7200 feet (permit section 4.4.1). Contiguous areas of range site A and range site B seeded in the same year and receiving similar reclamation practices may be lumped together into one range site AB parcel. When the bond release blocks are comprised of both A and B range site areas, cover and production standards for range site A will be applied to the block relative to demonstrating reclamation success. In some cases, when small range site C parcels exhibit characteristics and uses consistent with adjoining A/B parcels, they may be included in the range A/B bond release block. When small isolated C parcels are included in a predominantly AB block, the more stringent success standards for range site A and/or B, as applicable, will be used on the entire block (Permit section 4.4.1.5).
