Additional support (cash acrd irz-kind) is being provided by: <br />• Collegiate Peaks Chapter Trout Unlimited, <br />• Trout Unlimited Abandoned Mineland Restoration Program <br />• Trout Unlimited Embrace-A-Stream Program <br />• Colorado Mountain College -Natural Resources Management Program <br />• Colorado Division of Reclamation Miiung and Safety <br />• Bureau of Land Management, <br />• Colorado School of Mines <br />• U. S. Environmental Protection Agency <br />Description of New Location and Plan: The newly proposed plan is to install a sulfate <br />reducing bioreactor on the Little Frying Pan River at the Tiger Mine Complex. The only suitable <br />location for the bioreactor currently has a large mine waste dump sitting on top of it. Prior to the <br />treatment system construction, the BLM will remove large waste rock piles that sit in the stream <br />and clear a site for our project. Before that can be done, exploratory drilling of the pile and a <br />potential repository site must be completed. Additionally, Colorado Mountain College has <br />applied for Non Point Source Section 319 money to address nm-on and run-off controls at the <br />site, as well as install limestone channels to help raise the pH of the water that will enter the <br />treatment system. The landowner is fully on board with this project and will help out when and <br />where he can. Trout Unlimited is beginning the initial efforts of working out an Admiiustrative <br />Order on Consent with the EPA that will shield the organization and its partners from CERCLA <br />liability. We expect to break ground on the treatment system in May of 2010. <br />Final Technical Memo: Colorado Mountain College's Natural Resource Management <br />Program's Director, Kato Dee, prepared the following technical memo. 111 it is a detailed <br />description of how the Colorado Watershed Protection Fund grant was utilized for a bench scale <br />test. The resulting data and analysis is also included. <br />
