Grand River Park Project, M-2006-046 Response to Adequacy Letter of August 1, 2006 6 September 2006 Page 3 or a pigging for clean-out of the pipeline. In either case, the above-ground feature is integral to the below-ground pipeline and part of the same alignment, as mapped on revised map exhibits. There are no gas wells existing on the subject property at this time, though future pad sites are depicted on the applicant's exhibits, and the applicant has located all oil and gas lines on the property, as required by Rule 6.4.3(b). 5. In accordance with Rule 6.4.3(e), please show the types of vegetation covering the affected lands. In particular, please delineate the Cottonwood-dominated riparian area at the northeastern fringe of the permit area as described in Exhibit J -Vegetation Information. The types of vegetation covering the affected lands are delineated on Exhibit C- 1, as revised. As described in Exhibit J, the site has three distinct vegetation types: Degraded pasture, a Cottonwood fringe near the Colorado River, and wetland/wet meadow areas. Revised Exhibit C-1 clearly differentiates between these areas, though many areas classified as "wet" were put to productive use and therefore show vegetative characteristics of degraded pasture. The Cottonwood-dominated riparian area is mostly off-site, to the east along the banks of the Colorado River, with tree cover on the site consisting primarily of Russian olive. 6. On page seven of the Mining Plan, the applicant states that no significant overburden covers the site, yet the applicant indicates in numerous places throughout the Mining Plan that topsoil and overburden will be stripped and stockpiled as needed. Please clarify if overburden will need to be stripped and stockpiled, and if so, identify the locations of overburden stockpiles on Exhibit C-2: Mining Plan Map. The applicant is planning for a limited amount of topsoil and overburden removal based on investigation of the soils and aggregate deposit. The berms to be provided surrounding the enclave property at the south of the site will have a capacity of approximately 7,000 CY for topsoil (to be vegetated as appropriate for soil preservation and aesthetic effect). The material for these berms will be recovered from the area to be established as the Phase 1/2 Processing Area, approximately 10 surface acres in the southeast of the Phase 3A Mining Area. It is necessary to excavate the processing area prior to setting the plant and other equipment (to ensure structural stability and proper drainage), so it is necessary to stockpile the material recovered in this initial site work. Any additional excess material generated prior to the commencement of concurrent reclamation (e.g., backfilling areas where mining has been completed) will be placed in a temporary stockpile within the Phase 1/2 Processing Area, as illustrated on revised Exhibit
