has been carried out through two primary agents, outside services or Yoast <br />Reclamation Department personnel and complies with applicable regulations and <br />procedures. <br />Grazhkg. Livestock grazing (sheep only) has been conducted on Yoast reclaimed lands <br />since 2009. The grazing season has historically been from August through September. <br />Livestock grazing has been conducted annually and livestock numbers have increased as <br />more reclaimed acres have become available and the vegetation communities have <br />continued to mature. Stocking rates have been developed from ongoing vegetation <br />monitoring data and a goal of proper use at 50% forage utilization has been a basis of <br />management, as has pasture development for management and grazing systems. Annual <br />precipitation and the effects on current year's production are factored into annual <br />management. Results of annual grazing are presented in the Yoast Annual Reclamation <br />Reports submitted yearly to CDRMS to demonstrate utility for the postmine land use. <br />REVEGETATION SUCCESS (PHASE III) <br />The SL -6 Phase III bond release includes lands within the BRB-1 block areas to total 277.2 <br />acres. The parcels within the BRB-1 area were revegetated between 2001 and 2007 with a small <br />area of interseeding in 2009. Phase 11 bond release encompassing the BRB-1 Phase III area has <br />been approved based on the previous SL -3 submittal. These lands have established vegetation <br />that meets the minimum ten-year liability period and are able to support the approved post - <br />mining land uses. Phase III revegetation success evaluations have been based on the applicable <br />regulatory success standard requirements and procedures spelled gut in Tab 22 "Revegetation <br />Plan" of the approved Yoast permit, Rules 3.03.1(2)(c), 3.03.1(4) and 4.15.8 and the Division's <br />Guideline Regarding Selected Coal Mine Bond Release Issues (April 1995). Revegetation <br />success is demonstrated by meeting the appropriate cover, production, woody density and <br />species diversity success standards based on statistically valid sampling and analysis. Species <br />composition and diversity requirements are assessed through the vegetation cover data and <br />evaluations using a species diversity assessment specifically developed for SPL reclaimed lands <br />as detailed in Tab 22. <br />SL -6 - 6 <br />
