Your request was made in <br />anticipation of the Division's recent proposed decisioa to approve Bond Releax Application No. 3' <br />(SL•3) for the Hayden Gulch Mine. " <br />The Division believes that water monitoring az Hayden Gulch Mine is no longer necessary as indicated <br />by the impacu to surface water and ground wazer that are listed on pages l3 and 14 of the Division's <br />findings document prepared for SL-3, dated May 23, 1999. Also, on page i S of that findings <br />document, the Division found that the permittee, H-G Coal Company had successfully completed all <br />surface coal mining reclamation operations in accordance with the approved reclamation plan. Those <br />operations included the mine's water monitoring plan. Based on the completion of the water <br />monitoring program, and the lack of a technical basis for further monitoring, the Division approves <br />cessation of further water monitoring az the site. I discussed this approval with David Berry, Coal <br />Program Supervisor, on June 23, 1999 and he expressed his support. <br />Cessation of water monitoring will be consisunt with the intentions of the remaining mining and <br />reclamation permit. When the proposed bond release becomes final, the Hayden Gulch Mine mining <br />and reclamation permit area will be reduced to 6.8 acres comprised of three shrub enclosures and a <br />slump area. The purpose of maintaining bond liability on this 6.8-acre remnant of the original 1276- <br />acrc permit area is to ensure successful rcvegetation sad for demonsvating ground stability. <br />If you have questions or are in need of additional information, please contact me. <br />Sincerely, <br />T•y~ ,~.U.1~...G>,t.4 <br />Tom Kaldenbach <br />Environmental Protection Specialist <br />ce: David Berry, CDMG <br />STATE OF COLORADO <br />
