• 4.4.1.5 Bond Release Area Delineation <br />Bond release will be accomplished on particular areas of reclamation by means of bond release blocks. <br />Bond release blocks will consist of one or more reclamation parcels which comprise the area of land for <br />which a single bond release application is made. Reclamation parcels will be delineated as more or less <br />contiguous areas of uniform land use that were graded and/or seeded during the same year, with gen- <br />erally the same reclamation practices. When a bond release block consists of one or more reclamation <br />parcels, the parcels must together comprise or be contained within a single logical land management <br />unit. As used here, logical land management units are defined and discussed in CDMG's GUIDELINE <br />REGARDING SELECTED COAL MINE BOND RELEASE ISSUES, dated April 18, 1995. <br />Bond release blocks for range site C reclaimed areas will always be comprised solely of range site C <br />reclamation parcels. Conversely, because of the similarity of their post-mining land uses, parcels from <br />range sites A and B may be lumped together to form an individual bond release block. Moreover, con- <br />tiguous areas of range sites A and B that were seeded in the same year and received similar reclamation <br />practices will in many situations be considered a single reclamation parcel. When bond release blocks <br />are comprised of both range site A and range site B reclaimed areas, cover and production standards for <br />range site A will be applied to the block relative to demonstrating reclamation success. Range site A <br />standards will be applied because they are more stringent than range site B standards (Sections 4.4.1.1 <br />and 4.4.1.2). <br />• 4.4.1.6 Vegetation Sampling Methodologies for Deterrninina Reclamation Success <br />Success standards for cover, production, stem density and species diversity are reported in sections <br />4.4.1.1, 4.4.1.2, 4.4.1.3, and 4.4.1.4, respectively. Section 4.4.1.5 describes how bond release areas will <br />be delineated. This section describes how statistically valid field sampling will be accomplished in order <br />to determine success of vegetation establishment against bond release standards. <br />For bond release purposes, vegetation sampling methodologies proposed for determining successful <br />reclamation generally follow the requirements of Rule 4.15.8 and CDMG's GUIDELINE REGARDING <br />SELECTED COAL MINE BOND RELEASE ISSUES, dated April 18, 1995. <br />Vegetation sampling designs at Trapper will generally utilize a simple random sampling approach within <br />bond release blocks. (Trapper does, however, reserve the right to use other design approaches <br />approved by CDMG as conditions may require.) Sampling locations will generally be established through <br />the use of random point selection. A sample point will be considered that location in the bond release <br />study area where cover, production and/or stem density measurements for a sample are taken. Cover, <br />production and stem density data will typically all be collected at the same random sample point loca- <br />tions, but depending on sample size and other considerations, data for these different parameters may <br />be collected at separate random locations. <br />• <br />4-122 <br />Revision: i <br />Approve : 2PIT `i8
