These roads are presented in Attachment 20-2 (Permanent Features)of the <br /> approved mine permit application package. Segments of the following roads occur within or adjacent to <br /> the current Seneca 11 West Mine permit area (See Map 3 for permanent feature locations): <br /> • Access Roads • Light Use Roads <br /> o Road G o LU-1 (1,450 feet) <br /> o Ridgeline Access Road o LU-IA (490 feet) <br /> o Road J o LU-1B (1,600 feet) <br /> o Road K o LU-3 (3,860 feet) <br /> o Road A o LU-4 (2,930 feet) <br /> o Routt County Road 53C o LU-5 (7,580 feet) <br /> o LU-6 (580 feet) <br /> Permanent Impoundments. Seneca 11 West Mine has retained multiple stock tanks and sediment <br /> ponds as permanent structures. Currently the mine has received full approval for three of the six sediment <br /> ponds to remain as permanent, Pond 005, 009, and 015. All the ponds have received approval by CDRMS <br /> to remain as permanent but the mine is currently working to receive the State Engineers Office (SEO) <br /> approval for the remaining three sediment ponds, 006, 016, and 017. The mining area included many <br /> stock tank structures, of which many have been retained as permanent structures. Stock tanks T-2, T-3, <br /> T-5, T-18, T-20, T-24, T-26, and T-27 have all received full approval to be retained as permanent <br /> structures. Land owner approval letters, SEO approvals, and pond demonstrations for the approved <br /> impoundment structures can be found in Appendix 20-2.1 and 2.2 of the approved mine PAP. <br /> FENCED SHRUB PLOTS <br /> The Seneca II West Mine Permit area includes ten fenced shrub plots that were part of the reclamation <br /> efforts of the Seneca II West Mine. These plots are remaining as permanent features along with the <br /> existing big-game proof fence enclosures. These enclosures where required by permit conditions during <br /> the ten-year liability term. Prior to final bond release the gates to the plots will be opened to demonstrate <br /> the shrubs can withstand the existing wildlife and livestock foraging pressure. <br /> POWERLINES AND SUBSTATION <br /> The Seneca II West Mine permit boundary consists of a single remaining substation and approximately <br /> 7,355 feet of powerline with poles throughout the property. The substation was constructed to provide <br /> electricity to the mining equipment and facilities during the mining operation. The Substation is privately <br /> owned by Yampa Valley Electric Association (YVEA). YVEA has provided a letter requesting the <br /> substation remain as a permanent feature. <br /> 26 <br />
