quantitative cover sampling. The revegetation success standard for these reclamation areas <br />shall be; vegetation cover of the reclaimed area will be successful when total live vegetation <br />cover of the reclaimed areas is equal to or greater than 90 percent of the total vegetation <br />cover revegetation success standard, that being 20%, with 90 percent statistical confidence. <br />2.8.6 REVEGETATION SUCCESS CRITERIA: MIXED PRE- & POST-SMCRA INDUSTRIAL <br />OR COMMERCIAL RECLAIMED AREAS (CATEGORY F) <br />A number of areas at the mine were disturbed either pre- or post-SMCRA. These areas have <br />an approved post -mining land use of industrial/commercial and have been developed for <br />that post -mining land use. These areas are regularly traversed and not commonly revegetated <br />for their use (e.g., NFELLC facilities, and similar areas). These areas will not have a <br />revegetation standard for final revegetation success, as they have been requested to be left <br />post -mine by the surface landowners, and any erosion from these areas is minimized and <br />controlled by in-place best management practices. <br />2.8.7 REVEGETATION SUCCESS CRITERIA: POST-SMCRA, UNDEVELOPED LAND <br />RECLAIMED AREAS, USING A REFERENCE AREA (CATEGORY G) <br />The following will be the revegetation success criteria for the post-SMCRA areas at the mine <br />where the post -mining land use is undeveloped land: <br />Vegetation Cover <br />Vegetation cover of the reclaimed area will be successful when total live vegetation cover of <br />the reclaimed areas is equal to or greater than 90 percent of the total herbaceous vegetation <br />cover of the applicable approved reference area with 90 percent statistical confidence. <br />Herbaceous Production <br />Herbaceous production (defined as current year above -ground biomass of herbaceous <br />vegetation) of reclaimed areas will be successful when total herbaceous production is equal <br />to or greater than 90 percent of the total herbaceous production of the applicable approved <br />reference area with 90 percent statistical confidence. <br />Woody Plant Density <br />There shall be no woody plant density revegetation success standard pursuant to the request <br />of the surface landowners that woody plants not be actively re-established on the reclaimed <br />areas of the mine. <br />Species Composition <br />The species composition revegetation success standard was derived from quantitative <br />sampling of the approved reference area, and represents the significant species contributing <br />to the composition of the reference area, based on seasonality, hfeform, and origin. <br />Species composition and a demonstration of the adequacy of the seasonal nature and <br />support of the post -mining land use of the reclaimed area vegetation will be successful when <br />TR -77 H-14 Revised March 2019 <br />
