C- 1981 -008 - SL-12 <br />Preliminary Adequacy Review <br />May 2010 <br />Page 4 of <br />The paragraph following the table must be amended to describe the statistical basis <br />for the conclusion that the cover criteria were achieved. In addition, the narrative <br />must include a statement confirming that the vegetation established on the reclaimed <br />area supports the approved land use. Species composition data from the BI -Logic, <br />Inc. report, would be the primary basis for the statement affirming that the vegetation <br />supports the approved land use. <br />4. The cover table in the Appendix B, Phase II Vegetation Sampling report is a working <br />spreadsheet. It provides all of the necessary data to allow for statistical calculation and <br />technical evaluation; however a final summary table needs to be included in the report. <br />The summary table should be of the general form provided in Attachment 1 to this <br />memorandum. The purpose of the table is to provide a clear and accessible summary of <br />the cover and composition of the sampled parcel. The table should list each plant species <br />by common and scientific name, a column for relative vegetation cover by species, a <br />Total Vegetation Cover Column, and the "Total Desirable" Column. Please provide a <br />Summary Cover table, in the general form requested. <br />5. In accordance with the bond release guideline p. , please provide a narrative sun unary <br />of the reclamation and management history of the parcels included ire the Phase II release <br />request. <br />6. Please provide specific infornmation'regarding topsoil subsoil replacement requirements <br />and thicknesses applicable to the Phase II release parcels, and provide narrative <br />explanation (based on sample data) to support the conclusion that the required <br />replacement thickness was achieved. Dist the soil thickness sample points on Map R-2 <br />that fall within the Phase II release areas, along with the thickness measured for each <br />point. All of the soil thickness sample points within. the Phase II area must list a <br />measured soil thickness; please provide any missing data. <br />Phase III .fond Release Request <br />WF C has requested Phase III release for 126.1 acres of irrigated pasture and 23.8 acres of <br />dryland pasture that were initially revegetted in 1998. The Division allows for Phase III bond <br />release upon successful completion of all reclamation plan requirements for the area in question, <br />including demonstration of conformance with all applicable reveget tion success criteria. <br />Regulatory criteria are specified in Mules 3.03.1(2)(c) and 3.03.1(4. Achievement of <br />compliance with applicable revegetation success criteria must be demonstrated for at least 2 of <br />the last 4 years of the minimum 10 year liability period, with year 9 being the initial allowable <br />comparison year. Additional information to be provided in a Phase III bond release application <br />is addressed in the Division's Guideline Regarding selected Coal Mane Bond Release Issues. <br />Success demonstration sampling for the Phase III request areas in SL-12 was conducted in 2007 <br />(Year and 2008 (Year 10. <br />7. Pages 2 6 through 2 8 of the -a plica.tion were revised in a submittal dated 3/9/10 to <br />incorporate discussion and a table "Soil Correction Table" regarding a soil factor <br />adjustment procedure allowed under approved permit [approved in TR- ] , for <br />comparison of Irrigated Pasture (IP) reclaimed area production to reference area <br />production.. The soil factor adjustments were not applied and were not necessary to <br />
