Pitch Reclamation Project Colorado Mined Land Reclamation Board — 2013 Annual Reclamation R <br />3. RECLAMATION ACTIVITIES IN 2013 <br />During 2013, primary maintenance and reclamation activities at the Pitch site focused on planting cattails <br />in the constructed wetlands area downstream from the North Pit lake embankment; site activities also <br />included the removal of pine seedlings on the downstream face of the sediment control embankment and <br />continued spraying of Canadian Thistle and Scentless Chamomile. All work was conducted in accordance <br />with applicable conditions in the Radioactive Materials License (RML) and the Pitch Reclamation Project <br />Procedures Manual. The various reclamation areas discussed in the following subsections are shown on <br />Figure 2. <br />3.1 Constructed Wetlands Areas and Adjacent Slopes <br />Reclamation related activities in 2013 consisted of continued improvements to the constructed wetlands <br />area near the location of the former Radium Treatment Plant (RTP) and the Indian and Tie Camp creeks <br />areas above the Sediment Pond. The RTP was demolished, backfilled and recontoured in 2001, with <br />grading and initial revegetation in 2002. Reclamation activities have included graded the steep <br />embankment behind the former RTP site, to reduce the slope sloughing and construction of a wetland <br />area in the drainage to improved sedimentation control and to stabilize the slope adjacent to and down <br />gradient from the RTP site. Activities have also included the development of wetland areas above the <br />Sediment Pond by constructing small dikes in the drainages to allow the creation of small sedimentation <br />basins, followed by the placement of timber slash in the drainage to retard flow velocity, and to trap <br />sediment forming a wetlands type condition. Photographs 1 and 2 reflect the growth of cattails and <br />sedges in the wetland area in the drainage near the former RTP site and Photograph 3 shows the <br />wetlands area above the sediment pond. <br />Photograph 1: Constructed Wetlands in 2013 on Indian Creek near area of old RTP site <br />Pitch 2013 Reclamation Report 14Apri12014.Docx 3 <br />
