Phase I bond release for these parcels occurred as a result of the following bond release actions <br /> shown in Table 3. <br /> Table 3. Summary of Prior Phase I Bond Release for Parcels in SL19 Phase II Request <br /> Parcels Bond Release Permitting <br /> Action <br /> AB09, AB 12, FA 11,FA 12, ZA 12, KA 11 SL 14 <br /> AB 13, KA13, ZA13 SL15 <br /> Phase II Bond Release <br /> Rule 3.03.1(2)(b) states: <br /> "Up to eighty-five percent of the applicable bond amount shall be released upon the <br /> establishment of vegetation supporting the approved post-mining land use and meeting the <br /> approved success standard for cover based on statistically valid data collected during a <br /> single year of the liability period." <br /> And, regarding Phase II bond release, Rule 3.03.1(3)(b) states: <br /> "No more than(60)percent of the bond shall be released so long as the lands to which the <br /> release would be applicable are contributing suspended solids to streamflow or runoff <br /> outside the permit area in excess of pre-mining levels as determined by baseline data or in <br /> excess of levels determined on adjacent non-mined areas." <br /> Regarding Phase II bond release, the approved reclamation plan calls for: <br /> o Specific topsoil replacement depth <br /> o Vegetative cover standard <br /> o Post-mining land use <br /> o Sedimentology estimates. <br /> The approved post-mining land use for the land applicable to SL19 is rangeland/wildlife habitat. <br /> The 3 76.1-acre bond release block, the sub j ect of this bond release application (SL19), has been <br /> reclaimed for rangeland/wildlife habitat. The revegetation plan is designed to achieve the approved <br /> post-mining land use. <br /> After final backfilling and grading, topsoil is required to be placed on the spoil to a depth of 18 <br /> inches on cropland and 12 inches on rangeland. A variation of+'- 2 inches is allowed due to <br /> compaction and operational considerations as per TMI's permit(page 4-256). <br /> There are three different range vegetation criteria to which the reclaimed parcels are compared as <br /> discussed in section III of this document, Observation and Findings: range sites A,B and C. TMI <br /> utilizes a technical standard for demonstrating revegetation success for vegetative cover on <br /> reclaimed parcels. TMI has identified specific percent effective cover standards for each range <br /> site category. The standards were calculated using the Universal Soil Loss Equation(LISLE), and <br /> designed such that soil loss due to rill and sheet erosion will not exceed pre-mine levels.
