2.05.4 RECLAMATION PLAN EFMC subtnitted a notice of permanent cessation for the Raton Creek Mine to the Division on November 19, 1991. Following permanent cessation of operations, EFMC has permanently sealed all mine portals, according to the procedures outlined in Section 2.05.4 (2)(p~ of this permit application, a majority of the surface facilities have been dismantled and stored at the site, and the facilities disturbed azea east of the prep plant foundation has been backfilled and graded according to Section 2.05.4 (2)(c) of this permit application. Redamadon of the site in its current con5guradon will include of the following actinides: • Removal of the remaining structures (except for the structures which will remain at the request of the land owner) • Backfilling and regrading of the remaining highwall in the Mine 2 portal area. • Topsoil replacement • Soil preparation and revegetation of the mine disturbance azea The proposed reclamation activities will result in the proposed post-mining configuration shown on Map 17, Post-mining Topography and Figure 17-1, Redamadon Project 2 Plan. At the request of the landowner the following facilities will remain: • Sediment Pond (to be modified for use as a permanent stock-watering pond) • Prepazadon plant foundation • Concrete building adjacent to prep plant foundation • Shop Building • Access Road • Pond Light Use Road • Water Tanks • Gazage and adjacent concrete pads (2) All ocher remaining facilities will be dismantled and removed. All remaining concrete foundations will be broken up and disposed of on site. Fox locations of facilities that will remain refer to Map 17, Post- mining Topography and Figure 17-1, Reclamation Project 2 Plan. The existing pond will remain as a permanent structure. Once vegetation is established in the reclaimed areas, and all regulatory requirements are met, the emergency spillway will be lowered to 6,346 feet. The final pond capacity will total 1.8 acre feet assuming a sediment level of 6,341 feet. To increase the ponds dead storage, EFMC will add 2.9 feet to the primary spillway (flinch riser) to bring the invert elevation up to 6345 feet. Watershed Diversion Ditches 1 and 2, which run along the northern edge of the refuse pile, will remain with the exception of Section C of Ditch 1. This section will be eliminated allowing the ditch to run in the natural drainage and discharge directly into the permanent stock pond. Designs for these channels can be found in Section 2.05.3(4) of the Permit. Post Mining Ditch (PMD) No. 1, Refuse Ditch 1, and Mine Access Road Diversion Ditches will remain. Watershed Diversion Ditches (WDD) 3, 4, and 5 and Refuse Ditch 2 will be reclaimed. Following removal of WDD 3 and 4, PMD 2, 3, and 4 will be constructed. The following summazizes disturbance area acreages corresponding to the revised reclamation plan: PR-04 482R Revised 02/03
