Exhibit E <br /> Page 9 <br /> Existing root zones,plants, and other organic materials will be recovered during the pre-stripping activities. As <br /> demonstrated by pre-mining conditions,the surficial soils currently serve as a viable growth medium for rangeland <br /> species. Concurrent reclamation will help to ensure that the material retains its characteristics as an adequate and <br /> viable growth medium. The material to be placed in TS-1 stockpile will likely be subject to routine interim <br /> revegetation enhancements, and as such, should similarly retain its characteristics as an adequate and viable growth <br /> medium(after replacement)at end of mine life. <br /> Surficial soils over the 0 to 12-inch depth horizon within the Permit Area are generally consistent with that same <br /> depth profile throughout the immediately surrounding area. No soil amendment or nutrient addition is planned as <br /> residual plant materials will remain present within the stockpiled material;and, straw crimping will be employed <br /> during the seeding process,as discussed below. <br /> Seedbed Preparation,Seed Mix,and Timing of Seeding <br /> The decommissioned plant site and any remaining disturbed areas will constitute the final stages of site <br /> reclamation,occurring only after all areas are mined out, and all feedstock material has been processed through the <br /> plant and sold or otherwise disposed. Mining areas will be seeded commencing in Year 3 as a component of <br /> concurrent reclamation,and this will continue on an annual basis through to the end of mine life.All primary seed <br /> application efforts are anticipated to be undertaken during the fall season of each year;however,ongoing <br /> monitoring and maintenance of revegetated areas may introduce some variability into the timing of seeding at <br /> localized areas where revegetation success objectives so dictate. <br /> • Plant Site Area <br /> Seedbed preparation will consist of removal all concrete foundations to a nominal 18 inches below <br /> grade,as well as removal of any/all concrete,asphalt,and crushed gravel from surfaced 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 /> compaction effects, and to ensure that residual plant root systems and organic materials are retained <br /> within the uppermost 8 to 12-inches. A nominal 8 to 12-inch cover of growth medium will then be <br /> applied across the area in its entirety; and the area will then be considered ready for seeding. <br /> • Process Discard Stockpile(PDS)Area <br /> CSC will utilize a dozer and/or excavator for crest reduction, as well as further overall slope reduction <br /> within the waste stockpile area,as warranted.In order to ensure full-depth burial of the concrete debris <br /> emplaced adjacent to the stockpile, slope reduction will incorporate the dozing of sufficient material over <br /> the top of the debris(i.e.,to ensure a nominal 5-to 10-ft cover depth;and,to ameliorate potential settling <br /> effects)such that the resultant slope will more closely approximate 5H: 1V in this locale.
