E-9 <br /> location, but on an overall average basis, remain within the targeted objective of 8- to 12-inches <br /> minimum. <br /> Existing root zones, plants, and other organic materials will be recovered during the pre-stripping <br /> activities. As demonstrated by pre-mining conditions, the surficial soils currently serve as a viable <br /> growth medium for rangeland purposes. Concurrent reclamation will ensure that the material retains <br /> its characteristics as an adequate and viable growth medium. The material to be placed in TS-1 <br /> stockpile will be subject to interim revegetation processes, and as such, should similarly retain its <br /> characteristics as an adequate and viable growth medium(after replacement)at end of mine life. <br /> Surficial soils in the 0-to 12-inch depth horizon within the Permit Area are consistent with that same <br /> depth profile throughout the immediately surrounding area. No soil amendment or nutrient addition is <br /> planned as residual plant materials will remain present within the stockpiled material; and, straw <br /> crimping will be employed during the seeding process,as discussed below. <br /> Seedbed Preparation,Seed Mix,and Timing of Seeding <br /> Plant site and(remaining) waste stockpile seeding will constitute the final stages of site reclamation, <br /> occurring only after all areas are mined out, and all usable feed material has been processed through <br /> the plant and sold or otherwise disposed. Mining areas will be seeded commencing in Year 2, and <br /> continue on an annual basis through to the end of mine life. All primary seed application efforts are <br /> anticipated to be undertaken during the fall season of each year; however, ongoing monitoring and <br /> maintenance of revegetated areas may introduce some variability into the timing of seeding at localized <br /> areas where revegetation success objectives so dictate. <br /> Plant Site Area: Seedbed preparation will consist of removal all concrete foundations to a nominal <br /> 18-inches below grade, as well as removal of all concrete and/or asphalt from paved areas. The inert <br /> debris will be placed (and consolidated to the extent practicable) within the pit void, adjacent to the <br /> process waste stockpile. Gravel or rock-surfaced areas will be removed (for similar in-pit disposal) <br /> and/or dozer ripped and sacrificed into the substrate. <br /> Once these steps are completed, an over-grading of the plant area portion of the site to re-establish <br /> approximate pre-mining ground contours and natural drainage pathways will occur. This may be <br /> followed by a discing of the surface, (if determined necessary), to minimize or mitigate any resultant <br /> Keenesburg No. 2 Mine_112 Reclamation Operation—November 22, 2019 <br />
