Sherman <br />Executive Director <br />Ronald W. Cattany <br />Division Direcor <br />Natural Resource Trustee <br />The Division of Reclamation, Mining, and Safety received your bond release objection on <br />October 5, 2007 for the Lorencito Canyon Bond Release No. 2 (SL-02). <br />This bond release application requests release of liability for lands approved for apost-mining <br />industrial land use. These areas are the coal loadout area, the former office area, and the <br />access and haul road ending at the disturbed area along the north ridge of Jeff Canyon. Bond <br />in excess of $950,000.00 will remain should this bond release request be approved. <br />Regarding your potential blast damage, the Coal Rules require that blast records be maintained <br />for inspection by the Division and the public for three years from the date of the blast. The last <br />blasting at the Lorencito Mine occurred in June 2002. During the time Lorencito was blasting, <br />all measurements and calculations done by Lorencito Coal Company and the Division <br />demonstrated the mine was in compliance with the allowable limits for peak particle velocity <br />regarding structures within one-half mile of the permit area. No post-blasting inspection is <br />required under the Rules. It is not possible for the Division to determine whether blasting at the <br />Lorencito Mine is the cause of cracks in your home more than five years after blasting has <br />ceased. <br />Please call me if you have any questions. <br />Sincerely, <br />Kent Gorham <br />Environmental Protection Specialist II <br />CC: Sandy Brown <br />Office of Office of <br />Mined Land Reclamation Denver Grand Junction Durango Active and Inactive Mines <br />
