Pitch Reclamation Project <br />Colorado Mined Land <br />Reclamation Board <br />2009 Annual <br />Reclamation Report <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 and 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 and 2008, finish grading was <br />conducted on the topsoil cover to eliminate any low spots where water could pond, and <br />to enhance drainage on and around the disposal cell. Harrowing, scarifying and <br />reseeding of the surface of the disposal cell area were completed in 2007, 2008 and <br />2009 to improve the cover stability. The vegetative cover on the disposal cell cover is <br />showing success. All reclamation work was conducted in accordance with conditions <br />in the RML and the Pitch Reclamation Project Procedures Manual. <br />• <br />6
