Pitch Reclamation Project . Colorado Mined Land Reclamation Board 2008 Annual Reclamation Report 2.0 LAND DISTURBED IN 2008 Surface disturbance in 2008 included: work associated with the site improvements in the constructed wetlands area (former site of the [Radium Treatment Plant] RTP); final grading to enhance drainage and erosion control off the cover of the disposal cell at the toe of the Tie Camp Creek Low-Grade Ore Stockpile (Tie Camp Creek Disposal Cell); and cleaning of sediment traps on lower Indian and Tie Camp creeks to prevent heavier sediment from entering the Sediment Pond. These activities occurred on ground already disturbed by project related facilities. 3.0 RECLAMATION ACTIVITIES IN 2008 During 2008, reclamation activities at the Pitch site focused on final grading and . seeding of the cover on the Tie Camp Creek Disposal Cell. Noxious weed control (Canadian Thistle) was limited in 2008 due to the frequency of rainstorms, but will continue in future years. All work was conducted in accordance with applicable conditions in the Radioactive Materials License (RML) and the Pitch Reclamation Project Procedures Manual. 3.1 Constructed Wetlands Area and Adjacent Slope Reclamation related activities in 2008 consisted of improvements to the constructed wetlands area (area of the old RTP building and the adjacent drainage). The former site of the Radium Treatment Plant (RTP) was backfilled and recontoured in 2001, with grading and initial revegetation in 2002. These activities included the steep embankment behind the former RTP site, where the area was graded to reduce the slope and prevent sloughing. Reclamation in the area has consisted of recontouring to facilitate improved sedimentation control and to stabilize the slope adjacent to and down gradient from the site. Activities have included construction of small dikes in the drainage to allow the creation of small sedimentation basins followed by the placement of timber slash in the drainage to retard flow velocity and to trap sediment forming a wetlands type condition. During 2008, the road running through this area was moved from the south side of the drainage to the north side to allow more sunlight on the road in the spring and to provide a larger area to trap sediment from run-off water coming from the shop area. Since 2002, stabilization measures have included planting of 1,100 lodge pole pines, and 200 spruce trees on the contoured area and planting of 500 lodge pole pine and 200 Douglas fir seedlings on the slope opposite the constructed wetlands area.
