Stormwater Permit Annual Report, Coal Basin Reclamation Construction Projects <br />2005 <br />Permittee: Colorado Division of Minerals and Geology <br />Facility Name: Coal Basin Mine Reclamation Construction <br />Mailing Address: 1313 Sherman Street Room 215, Denver Co. 80203 <br />Permit Cert. No.: COR-040204 <br />A. The Stormwater permit was issued on November 6, 1998 to the Colorado Division of <br />Minerals and Geology. The permit was renewed on September 21, 2001. The permit was issued <br />for the purpose of completing reclamation operations at a portion of the now inactive Coal Basin <br />Mine. The operating permit for the Coal Basin Mine was revoked by the Colorado Mined Land <br />Reclamation Board in 1992. Minerals and Geology is accomplishing reclamation of the site with <br />proceeds received via the bankruptcy plan filed by the former permittee. Minerals and Geology <br />is required by statute to accomplish reclamation of this site. Minerals and Geology will apply for <br />permit release in 2006. <br />The majority of reclamation construction within the Stormwater permit area was accomplished in <br />1999. No reclamation maintenance work was necessary within the permit area in 2005. <br />Monitoring of past reclamation construction occurred during the summer and fall of 2005. <br />The Best Management Practices implemented during the 1999 construction season appeaz to <br />have been successful in containing sediment generated from the reclaimed area. Reclamation <br />completed, Best Management Practices installed at each construction area, maintenance <br />accomplished and vegetative cover established is summarized below. <br />A portion of the mine property was recently sold. Some of the areas covered in this permit are <br />located on this property. The new owners have begun to develop the property as a recreational <br />site, thus the land use for this portion of the former mine site is changing. Minerals and Geology <br />has completed its reclamation obligations in this area, and has ended its reclamation related work <br />on private property. <br />Old Refuse Pile Project Area <br />Huntsman Project <br />The Huntsman Project Area was inspected following snow melt. Silt fence and dozer hummocks <br />were the primary Best Management Practices employed in this area. The dozer hummocks were <br />very effective in disrupting runoff patterns, and at containing sediment generated from the <br />Project Area. Due to the effectiveness of the vegetative cover at controlling erosion, the silt <br />fence was removed from this area. The vegetative cover at the Huntsman Project Area was <br />
