Revegetation monitoring report (when applicable) 4. ~ Updated existing light use road locations and culverts with specific light use road culvert design calculations 5. Submittal of existi rig graded topography with comparison to proposed postmining topography 6. ~ Wildlife monitoring reporting when conducted Testing for Successful~Reclamation The following discussion details 'the applicable success criteria, methods to be used in' measurement of parameters, comparisons to be made between reclaimed and undisturbed areas, and statistical tests to be performed. An extended reference area approach will be used for assessing successful revegetation for the parameters of cover and production at both the II-W and II-W South Extension areas. Woody plant density and species diversity success criteria will be based' on technical • performance standards. As discussed later in this section, seasonal variety as a success parameter.is not applicable because of the cool season vegetation dominance in the native ' areas. In addition, premining data for the wetter phase of the mesic drainage type (Dry-Creek area in II-W:~ Hubberson Gulch in the II-W South Extension areal will be used as success standards for this minor type lin terms of areal~extentl. The proposed revegetation plan for this mesic drainage, type should also be kept in mirid when considering revegetation success criteria. "~ In March 1965,'the Division issued Peabody a.set of adequacy comments based on.the review of the Seneca II-W permit application. Included was a .comment regarding the then proposed two-acre .reference areas and their' comparability to the permit area. In May, 1985, as part of a Peabody response package, the extended reference area approach was proposed to alleviate . the concerns of the Division. The appfoach and response were approved as part of the August 5, 1985 Decision and Findings of Compliance document for the Seneca II-W Mine permit. The Seneca II-W permit was signed on December 31, 1985. In response to Peabody's Permit Revision" 1 (PR 11 to the Seneca II' W permit, the Division . ~ issued a Preliminary Adequacy Review letter on March 11, 1991 "which, in part, required ' documentation of the comparability of the extended reference area to the mine affected area. Peabody responded to this requirement as part of an April 26, 1991 response package ' ~ ~ ~ 37 Revised 1 /99
