FCM will reseed the topsoil stockpiles with the following recommended seed mix to provide a vegetative cover to enhance stability and organic viability until final reclamation of the mine phases. [Topsoil Stockpile Seed Mix:annual rye at 5 pls/ac&triticale at 10 pls/ac] 2) The existing access road does enter onto the proposed mining permit boundary as shown on Exhibit E-1. Minor improvements to this section of road within the proposed mining boundary include widening and regrading to accommodate truck traffic. Ultimately,this section of road will be mined and reclaimed as shown on Exhibit E-2. It is important to note,as mentioned in Exhibit C,(g.), FCM has initial approval from the State Board of Land Commissioners(SBLC)office to provide an easement for the establishment of a more direct access route to US 160. FCM will seek an access permit from CDOT to provide intermittent egress and ingress for future road projects. 3) As stated in Exhibit C, (1), FCM does not expect to intercept groundwater during mining excavation. Earlier test holes indicated the water table is well below the bottom of the mineable deposit. Should groundwater be encountered, FCM will adjust the mining depth accordingly to prevent any intrusion into the water table. P.O.Box 1969 0 Bayfield,CO 81122 o 970-247-2172 0 FAX:970-259-3631
