<br /> <br /> <br /> <br />3.2 Tie Camp Creek Disposal Cell <br />' In 2001 and 2002, dismantled building material from the former RTP, concrete and <br />contaminated soils removed from the immediate drainage, were removed and placed <br />' in a Disposal Cell near the toe of Tie Camp Creek Low-Grade Stockpile. This cell was <br />created in mid-1990 as a clay lined) repository for materials dredged from the Sediment <br />Control Pond. The cell, as shown on Figures 2 & 3, was left open with sufficient <br />capacity for the RTP demolition material. The demolition material and contaminated <br />soil placed in the cell were crushed and compacted. In 2003, the cell was shaped and <br />prepared for the placement of a clay cap. Placement and compaction of a clay cap <br />' was completed in 2004. A final layer of topsoil (minimum 24 inches) was added and <br />compacted on top of the clay cap during 2005. In 2007, finish grading was conducted <br />on the topsoil cover to eliminate any low spots where water could pond and to enhance <br />' drainage on and around the disposal cell. Harrowing, scarifying and reseeding of the <br />surface of the disposal cell area were completed in 2007 to improve the cover stability. <br />All reclamation work was conducted in accordance with conditions in the Radioactive <br />' Materials License and the Pitch Reclamation Project Procedures Manual. <br /> <br />0 <br /> <br /> <br /> <br />7 <br /> <br /> <br />Pitch Reclamation Project <br />Colorado Mined Land <br />Reclamation Board <br />2007 Annual <br />Reclamation Report <br /> <br />
