Environmental Protection Plan, Schwartzwalder Mine 7-1 <br />• <br />7. FACILITIES EVALUATION <br />The Schwartzwalder Mine has been reclaimed, and all former structures (including the office/shop <br />complex, warehouse, stormwater retention ponds, core shed, guard shack) except the water treatment plant <br />building have been removed. Reclamation and closure activities occurred at the mine site over 15 years, <br />with most of the facilities reclamation occurring after mining ceased in 2000. The ore sorter was <br />dismantled and removed from site in 1999. Uranium-contaminated soils associated with a historic pond <br />were removed in 2001. Waste rock piles were consolidated, recontoured, and revegetated. The Steve and <br />Pierce adits were sealed in December 2007 with final contact grouting occurring in January 2008. Removal <br />of the storage ponds is scheduled for 2010. A summary of reclamation is provided in Table 7-1. <br />Table 7-1.

This facility has not discharged since June 30, 2002. <br />The water treatment plant is scheduled to be removed at some time in the future. The water treatment plant <br />is not designated as an Environmental Protection Facility subject to the provisions of Rule 6.4.20(7)(e) <br />because it does not contain any designated chemicals and is scheduled for removal and reclamation. <br />4109C.100419 Whetstone Associates
