2010 Climax Mine Reclamation Report Vail Class A biosolids were imported to the site and used for reclamation maintenance or new reclamation in difficult to access areas. In total 100.5 acres were treated with biosolids in 2010. In July 2010, the biosolids production pad was graded and repaired. Climax personnel worked with Parker Ag and facilitated the import of gravel and rock to patch holes that emerged during the winter. In August 2010, Climax hosted a field tour for biosolids producers, USFS contacts, CO state regulators, and Parker Ag. The tour was very successful and helped to foster communication between partners and interested parties to Climax's biosolids operation. New Reclamation New reclamation was completed on 123.2 acres in 2010. This included areas never previously reclaimed, reclaimed areas that had been subsequently re-disturbed, and a few areas were reclamation had not been successful the first time. Seed Mixes In 2010, several new reclamation seed mixes were submitted as a part of the Climax Mine permit amendment (AM-06). A large quantity of the old Climax seed mix was ordered in 2005 and several bags were still available in 2010; however, there was not an adequate supply for all 2010 reclamation. When the old seed mix ran out in the middle of the reclamation season, Climax management ordered the new mix to complete the remaining 2010 reclamation. Thus, some areas were seeded with the old mix (Table 2) and some with the new mix (Table 4) in 2010. Additionally, Climax ordered some of the wetland seed mix (Table 3) outlined in the permit amendment for use on the wet areas on Robinson TSF. 1 Dam The majority of 1 Dam was limed and seeded after it was capped. However, no organic amendments were applied and the reclamation has never been successful. In 2010, biosolids were applied to the southern-most portion of the dam face, incorporated and the area was seeded with the new seed mix (Areas 16 & 19 on Map 2). A total of 10.9 acres were reclaimed. A small area on the northern-most portion of the dam was reclaimed in 2004 using available topsoil. This reclamation has been very successful. In 2010, a contractor working in this area re- disturbed 2.3 acres of the reclamation. This area (Area 6 on Map 1) was subsequently regarded and reseeded with the new seed mix. 3 Dam In 2009 and 2010 a seep on the face of 3 Dam was repaired. This seep had caused some erosion through established reclamation at the base of the dam. After Climax personnel repaired the erosion, biosolids were placed, incorporated and seeded with the new Climax seed mix. A 0.6 acre area was reclaimed (Area 1 on Map 1). 10 Mile TSF In preparation for increasing the elevation of 10 Mile TSF, topsoil and vegetation was stripped around the edges of the pond in 2008 and 2009. Several of these stripped areas were seeded and hydromulched in 2009, the remaining areas (Areas 2 - 5 on Map 1) were completed in 2010. A total of 1.6 acres were seeded with the old seed mix and hydromulched in 2010. The hydromulch was applied with the addition of 1000 lbs/acre of Biosol to provide organic matter and nutrients Habitat Management, Inc. 2 February 2011
