The Pond #1 shoreline length is approximately 4745 feet and the Pond /12 <br />shoreline is approximately 3792 feet. With a 50 foot wide maximum pond perimeter <br />topsoil stockpile/road "halo" or "buffer" area, a total of 9.80 acres will be <br />concurrently reclaimed. The perimeter area reclamation will have undisturbed pasture <br />(or hillside - east side of site) outside the perimeter road, then a slightly raised road in <br />the middle (approximately 10 feet wide) and then a maximum 3:1 slope to 10 feet <br />below the average water surface elevation down to the pond edge. The average water <br />level elevation is estimated to around 6194 feet AMSL. <br />Any and all topsoil found within the excavation/pond footprints at the site will be <br />stripped (as necessary) and stockpiled as described above for use in site reclamation. <br />Except for the 25 to 50 perimeter stockpiling/road zone, disturbance will be minimal <br />to the adjacent remaining pasture areas out -side the excavation footprints. The <br />planned site reclamation will provide additional wildlife habitat within the Yampa <br />River Basin corridor. <br />Depending on local needs and market conditions, mining and processing for road - <br />base, fill material and asphalt pavement may take from 5 to 15 years or longer. <br />Processing operations may be temporally located at the site from time to time. <br />Portable mobile process equipment for crushing, screening and asphalt production <br />will be mobilized as necessary and will have all necessary construction and air permit <br />for such equipment. Process equipments may be idle and stacked pending further use <br />from time to time. The site is not visible from either the north (Hwy 40) or the south <br />(Hwy 394) being effectively screened by the topography and large trees. <br />All areas of the site to be excavated are currently fenced pasture areas. All <br />disturbed areas will be reclaimed to the water surfaces or to the pasture/road/riparian <br />area surrounding then ponds. All stormwater will be contained under the site SWMP <br />and general Stormwater Permit. Ditching, silt fencing, berms, bales and other site <br />stormwater BMP's will be used as part of site stormwater controls. The area by the <br />gate will be the final reclamation area at the site and will be less than 3 acres. Mining <br />activities will begin in both pond areas on the north ends and expand south and <br />towards the central road, then toward the site access gate area. <br />The access road and pond perimeter roads will have sufficient drainage and berms <br />to allow for storm runoff and sediment retention. Topsoil stockpiles to be left for <br />more than 1 growing season will be seeded with the USDA recommended seed mix <br />via broadcast method for stabilization. Vehicle, haul truck and equipment speeds will <br />be 15mph or less on the access road. The access road and gate will remain for the <br />landowner/applicant as legal access to parcel and will require no reclamation. <br />WestWater Engineering <br />APPENDIX C - 5 July 2012 <br />
