The substation was constructed to <br />provide electricity to the mining equipment and facilities during the mining operation. The <br />Substation is privately owned by Yampa Valley Electric Association (YVEA). YVEA has <br />provided a letter requesting the substation remain as a permanent feature. <br />FENCED SHRUB PLOTS <br />The Yoast Mine Permit area includes six fenced shrub plots that were part of the reclamation <br />efforts of the Yoast Mine. These plots are remaining as permanent features along with the existing <br />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 <br />demonstrate the shrubs can withstand the existing wildlife and livestock foraging pressure. <br />SEDIMENT PONDS <br />Permanent pond demonstrations have been approved for three of the five remaining sediment <br />ponds. The three sediment ponds that have CDRMS and the State Engineers Office (SEO) <br />approval include ponds 10, 13, and 14. SPL plans to get approval on the remaining sediment ponds <br />to leave them as permanent features as well. The three permanent ponds meet the criteria specified <br />under Rule 4.05.9(13) and will be used to support the post mining land use. The permanent pond <br />demonstration can be found in Appendix 20-1.2 of the approved mine PAP. <br />STOCK PONDS <br />Within the Yoast permit area there are two ponds that have been specified as "Stock Ponds", ST- <br />1 and 11A. Both of these stock ponds have been approved through the CDRMS and the SEO to <br />remain as permanent features. They each have a storage capacity of less than two -acre feet and an <br />embankment no greater than five feet high measured from the invert of the spillway to the upstream <br />SL-8 - 18 <br />
