COLORADO DEPAR'T'MENT OF PUBLIC HEALTH AND ENVIItONMENT <br />WATER QUAI.TfY CONTROL DIVISION <br />Water Quality Proteetiom Section <br />Memonmdmm <br />~~ To: File <br /> From: Jon Kubic ~~ <br />w~ <br />Date: Se <br />tember 28 <br />1999 <br /> p <br />, <br />~ Subject: Inactivation Request <br />~ H-G Coal Company Hayden Gulch Mine <br /> CDPS No. COG-SSOOl8 <br />~~ Routt County <br /> <br />-i The permittee has requested inactivation. <br /> The Colorado Division of Minerals and Geology (CDMG) has recently granted release of Phase II and <br />{ Phase III bond. As a condition of this approval, the CDMG has authorized leaving the two sedimentation <br /> ponds that are the sources of the remaining discharge points under this permit for ux at livestock and <br /> wildlife watering ponds. As such, the potential for point source discharges from thex ponds will remain, <br /> however, the sources will no longer be a regulated industrial activity but anon-regulated agricultural <br />1 activity. <br />~ Additionally, during my June 1998 site visit, I observed that there arc at least three spoils springs that <br /> remain. None of these contribute significant flow and they usually do not reach either of the ponds. <br /> Because they do not impact surface water, the CDMG has jurisdiction. They have determined that these <br />_ spoils springs are not of significant concern. Thera is no basis for the Division w disagree. <br />~ <br /> On the basis of the information detailed in this letter, I recotmmend inactivation. I also recommend that <br /> the District Engineer not be requested to perform a site visit Thera would be no benefit from such a <br />1 visit. <br />.~ <br />~~ <br />-t~ <br />~~ <br />
