The BLM is conducting a Time-Critical Removal Action at the Venture Mine Site near Leadville, CO. The administrative record for this action is available on this website, as well as at the Lake County Public Library located at 1115 Harrison Ave, Leadville, CO 80461. The Administrative Record contains information that explains why the BLM is conducing this removal action at the Venture Mine Site. For additional information, please contact Melissa Smeins the BLM at 719.269.8523.
This removal action will mitigate threats posed by acid mine drainage (AMD) generated by surface water traveling over mine waste and tailings located on public land that is under the jurisdiction, custody and control of the U.S. Bureau of Land Management (BLM) and a small portion of private property located five miles west of Leadville, Colorado. The Site encompasses approximately 7 acres of uplands and stream shorelines. The majority of the Site is on public land; however, approximately one acre or 14% of the Venture Mine shaft and waste rock piles are on private lands.
This removal action will be conducted by the BLM pursuant to its lead agency authority for work on Federal land, which includes the Site and the consolidation repository. CDRMS will be conducting the contractor bidding process for the work and will implement the cleanup activities with the selected contractor, with respective oversight from the BLM. CMC NRM will be helping with the work by utilizing its heavy equipment program to install run-on/runoff diversion ditches and stream restoration work after waste pile removal has occurred.
