during the ten-year liability term. Prior to final bond release the gates to the plots will be opened <br />to 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 <br />ponds to leave them as permanent features as well. The three permanent ponds meet the criteria <br />specified under Rule 4.05.9(13) and will be used to support the post mining land use. The <br />permanent pond 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 I IA. 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 <br />an embankment no greater than five feet high measured from the invert of the spillway to the <br />upstream toe of the embankment. The permanent pond demonstrations for these stock ponds can <br />be found in Appendix 20-1.2 in the approved mine PAP. <br />MISCELLANEOUS BOUNDARY AND GRAZING FENCES <br />There are a variety of fences throughout the Yoast Mine permit area. All of the current fences <br />will remain as permanent features following final bond release. These fences delineate property <br />f <br />boundaries, and grazing areas. The fences support reclamation success along with post mining <br />land use. <br />HYDROLOGY <br />SPL's Yoast Mine hydrology program consists of five NPDES outfalls, three stock ponds, <br />numerous bedrock and alluvial monitoring wells, spoil springs, and upstream and downstream <br />surface water monitoring sites. Of these monitoring sites, only one stock tank lies within this <br />Phase III requested release area, Stock Pond 11A. Stock Pond IIA has been approved by the <br />SL -6 - 33 <br />
