Environmental Protection Plan, Schwartzwalder Mine 7-1 <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.

The facility did not discharge from June 30, 2002 to July, 2010. <br />The facility was upgraded in 2010 to provide appropriate secondary containment and equipped with a surge <br />• tank, prefiltration/control/ manifold skid, four ion exchange treatment vessels, and associated piping.
