Pitch Reclamation Project Colorado Mined Land Reclamation Board — 2016 Annual Reclamation Report <br /> 2N <br /> 1 <br /> Photograph 5: Cattail Growth in the Settling Pond Above the Sediment Control Pond Showing <br /> Recovery in 2016 from Beaver Damage in 2014 <br /> 3.4 Tie Camp Disposal Cell <br /> In 2001 and 2002, dismantled building material from the former RTP, concrete and contaminated soils <br /> removed from the immediate drainage,were removed and placed in a disposal cell on the Tie Camp Rock <br /> Dump. The Tie Camp Disposal Cell was originally created in mid-1990 as a clay-lined repository for <br /> materials dredged from the Sediment Control Pond. The Disposal Cell, as shown on Figure 3, was left <br /> open with sufficient 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 prepared for the <br /> placement of a clay cap. Placement and compaction of a clay cap was completed in 2004. A final layer of <br /> topsoil (minimum 24 inches) was added and compacted on top of the clay cap during 2005. In 2007 and <br /> 2008, finish grading was conducted on the topsoil cover to eliminate any low spots where water could pond, <br /> and to enhance drainage on and around the Tie Camp Disposal Cell. Harrowing, scarifying and reseeding <br /> of the surface of the Tie Camp Disposal Cell area were completed in 2007, 2008,2009 and 2010 to improve <br /> the cover stability and to minimize erosion. In 2011, the surface water drainage channel on the cell was <br /> repaired to correct erosion issues noted during an inspection by the CDPHE. The repair and reclamation <br /> work was conducted in accordance with an approved plan and conditions in the RML and the Pitch <br /> Reclamation Project Procedures Manual. The completion report, dated September 19, 2011, was sent to <br /> and approved by CDPHE and was included in the 2011 reclamation report on a CD at the back of the report. <br /> In 2014, waddles were placed in erosion areas to slow the movement of runoff and impede erosion from <br /> the face of the Tie Camp Disposal Cell. The repair work was monitoring closely in 2014 through 2016 and <br /> appears to have corrected drainage and erosion issues. <br /> In 2015, drill cuttings from the completion of two new piezometers into the underground mine workings were <br /> placed into the Tie Camp Disposal Cell. Drill cuttings resulting from the piezometer completion were placed <br /> into an approximately 15 ft by 15 ft area excavated to approximately 4 ft deep, compacted and covered with <br /> 6 <br />
