Box 825 Cheyenne, WY 82003 RE: Alma Placer; DMG File # M-1985=029; Storm water Permitt Ingm'ry Deaz Mr. Willits: COLORADO DIVISION O F M1N SRALS GEOLOGY RE CLANATION•NINING EAFETY•r CIENCE Bill Owens Governor Russell George Executive Director Ronald W. Gttany Division Director Natural Resource Trustee Per you request for information concerning storm water permits for the Alma Placer, the following information should address your questions. First, DMG is not the issuing authority for storm water permits in the state of Colorado. This is handled through the Colorado Department of Public Health and Envirorlment. As you know, our office issues reclamation permits and as part of that process, we notify other permitting agencies when we receive applications. In addition, all applicants aze required to inform us of other permitting agencies that have been notified in conjunction with their permit application to our office. During the permitting process we did not receive comment from CDPHE concerning the need for Reclamation Resources to obtain a storm water permit, however, even if we had been notified of such action, our pem3it issuance is not dependent upon receiving approval from every other permitting agency that may have an interest in regulating a given mining project. In order to obtain the fmal word on this matter, you should contact CDPHE. With that said, it is my understanding that storm water permits are not required if it can be demonstrated that a site can contain and treat storm water run-off from a100 yeaz-24 hour event. In the case of the Alma Placer, all storm water as well as process water run- off is directed into and captured by a series of infiltration ponds that treats the run-off and eventually infiltrates into the surrounding alluvium. This series of ponds are large enough to capture and treat runoff from a 100 yeaz-24 hour precipitation event at this time. To our knowledge, storm water and process water have never been released from a surface dischazge point at this site. Appazently, as a result of the site to capture and treat all runoff and process water, a storm water permit was not required. If you have any other questions, please contact me at (303) 866-4926.
