Box 467 <br />Golden, CO 80402 <br />RE: Request for Inactivation <br />Coors Energy Company - Keenesburg Mine <br />CDPS No. COG850038 <br />Weld County <br />Dear Mr. Neserke: <br />OQ CO <br />NeE <br />~ e <br />r <br />~ r876 ~ <br />Colorado Department <br />of Public Health <br />and Enviromnent <br />This letter responds to your Mazch l 1, 1997, letter in which you seek inactivation of CDPS permit coverage <br />for the Keenesburg Mine. <br />Mining has ceased at this facility and reclamation/revegetation is occursing. We understand that there is tittle <br />runoff at this site due to the porous nature of the soil and that runoff that does occur rarely reaches the <br />sedimentation pond. Additionally, you have stated that Coors Energy will be certain that discharge to surface <br />waters of the state does not occur by pumping to another holding pond on site if this ever becomes necessary. <br />We have corresponded with the Colorado Division of Minerals and Geology (CDMG) specialist and he <br />concurs that it is extremely unlikely that dischazge could occur from this site. On this basis, we will allow <br />the permit certification number COG-850038 for this facility to expire on June 30, 1997. <br />Please be aware that if conditions at the site change in the future to alter the need for a CDPS permit, the <br />Division may take appropriate action. <br />Please feel free to contact me at (303) 692-3605 if you have questions. <br />Sincerely, <br />fon C.
