During active surface coal <br /> extraction, the Number 7 Coal Seam of the Laramie Formation was mined. <br /> Previous activity at the site included the controlled disposal of ash and mine waste rock as a <br /> portion of the backfill of mine pits. The importing of ash was completed by CEC in April 2016. <br /> Some information on the mine's environment, operations, and reclamation activities are provided <br /> below. More detailed information about the mining and reclamation operations can be found in the <br /> PAP on file at the Division offices,located at 1313 Sherman Street,Room 215,in Denver, <br /> Colorado. The PAP is also available at https://dnrweblink.state.co.us/drms/search.aspx. <br /> The current permit boundary contains approximately 226 acres. According to the 2023 Annual <br /> Reclamation Report, approximately 443 acres have been disturbed over the life of the mine. Per <br /> records for bond releases, approximately 263.7 acres have been previously approved for Phase <br /> III bond release at the Keenesburg Strip Mine. An additional release of 30.55 acres is pending <br /> with Bond Release No. 12 (SL-12). <br /> Geology, Soils and Topography <br /> The permit area is located on level to gently rolling topography consisting of fine sand, which is <br /> wind-deposited material overlying weathered residual shale. The sand varies in depth from <br /> about 5 feet to 20 feet, is highly to moderately permeable, and is highly susceptible to wind <br /> erosion.
