( Colowyo) as a nomination <br />for a 2013 Coal Mining Reclamation Award which honors outstanding reclamation of coal <br />mines, and seeks to further the collection and dissemination of information about successful <br />reclamation techniques. <br />Colowyo once again demonstrated its commitment toward contemporaneous reclamation <br />in 2013 by reclaiming approximately 172.15 acres mine wide of which 162.6 acres were <br />reclaimed within the West Pit, and 9.55 acres were reclaimed in the South Taylor Pit <br />respectively. <br />Construction of the West Pit Fill has been completed. Beginning in late 2011 and <br />continuing to date, Colowyo has undertaken regrading a historic area which was comprised of <br />the original boxcut material of the West Pit. 2013 West Pit Fill final regrade efforts were <br />completed by primarily utilizing dozers, scrapers, and a trackhoe with a rock hammer. <br />Approximately 300 feet of rock armored channel was constructed in 2013. Approximately 4.6 <br />million yards of material were moved since 2011 to complete this project. This is a significant <br />milestone in the history of Colowyo Mine and the Colorado Division of Reclamation, Mining <br />and Safety ( CDRMS). <br />2013 marked the second step in construction of the West Taylor Fill in the South Taylor <br />Pit. In addition to final regrade work, approximately 1,200 feet of rock armored channel was <br />constructed in 2013. <br />In June 2013, a significant bond release effort was undertaken to reduce Colowyo's <br />exploratory drilling program Notice of Intent (NOI) bond liability. Through cooperative efforts <br />involving CDRMS and Colowyo environmental staff, Colowyo's NOI bonds were reduced by <br />over 95% from approximately $1,265,000 to just under $60,000. This is a reflection of the <br />diligent and sound reclamation efforts undertaken by Colowyo in years past at the conclusion of <br />AN EQUAL OPPORTUNITY /AFFIRMATIVE ACTION EMPLOYER CRAIG STATION ESCALANTE STATION NUCLA STATION <br />P.O.
