This nape was updated in caniunction with the USR Application. June 23, 2005 West, Inc. will comply with atl applicable Colorado water laws and all applicable Federal and State water quality laws and regulations. ~Idlife Presently, the area is used for farming and livestock grazing. However, some indigenous species may be temporarily displaced by the proposed mining activities. Existing riparian habitat areas along South Platte River will be undisturbed by the operation. Enclosed is a wildlife assessment performed by a qualified biologist, please review for additional wildlife information. The proposed reclamation of this site will add diversity to this site and enhance wildlife habitat. Topsoiling Topsoils in the proposed mine areas are predominantly Aquolls, Aquents, Bankard sandy loam, and Colombo clay loam. All suitable soil material will be salvaged for topsoil replacement. Topsoil will be replaced, where required, in reclaimed areas at a depth of approximately six to twelve inches. The topsoil will be segregated and stored separately from the overburden material as required by Rule 3.1.9(1), The mine plan map depicts the location and configuration of the topsoil berms. The berms will be protected from wind and water erosion by vegetative cover if in place more than one year. The stockpiles will be broadcast seeded (please see the Seed Mix for Upland Areas) and will be incorporated into our weed control program. Weed control consists of monthly inspections and, if necessary, chemical treatments in the applicable fall and spring seasons. Soil amendments are not expected to be required due to the nature of the soils. However, topsoil samples will be subjected to agricultural testing prior to reclamation to assess fertilizer requirements. The Sail Conservation Services (SCS) will be contacted periodically throughout reclamation for soil tests. SCS soil fertilizer recommendations, if any, will be followed. Revegetatior: Following topsoil replacement, reseeding will be performed according to SCS recommended practices. Based on SCS guidance for other local projects having similar surficial soils, the following revegetation procedures are anticipated: • Grass seed will typically be planted in unfrozen soil between October 1 and April 30. • Grass seed will be planted with a grass drill, or where necessary, with a broadcast seeder. ^ The proposed seed mix and application rates in pounds of pure live seed per acre aze described on the following pages. • Weed control practices will be implemented as required. The above procedures may be modified as conditions dictate. If a significant invasion of noxious weeds occurs, the area will be mowed periodically for control. Weeds will be Ft.
