Leadville Mine Drainage Tunnel Act of 2011 - Amends the Reclamation Projects Authorization and Adjustment Act of 1992 to expand requirements for the operation and maintenance of the Leadville Mine Drainage Tunnel, Colorado, to require the Secretary of the Interior to take any action necessary to maintain the structural integrity of the Tunnel to maintain public safety and to prevent an uncontrolled release of water from the tunnel portal. Makes the Secretary responsible for the operation and maintenance of the water treatment plant, including authorized sludge disposal. Authorizes the Secretary to offer to enter into one or more contracts with any appropriate individual or entity for the conduct of any required service.
Includes within the Tunnel any surface water diverted into it and water collected by the dewatering relief well installed in June 2008. Authorizes the Secretary: (1) to enter into an agreement with any other entity or government agency to provide funding for an increase in any operation, maintenance, replacement, capital improvement, or expansion cost that is necessary to improve or expand the Treatment Plant; and (2) upon entering into an agreement, to make any necessary capital improvement to or expansion of the water treatment plant.
Requires the Administrator of the Environmental Protection Agency (EPA) to consult with the Secretary regarding each feature of the proposed new or amended Record of Decision for operable unit 6 of the California Gulch National Priorities List Site that may require any alteration to, or otherwise affect the operation and maintenance of, the Tunnel or the water treatment plant. Authorizes the Secretary to implement any improvement to the Tunnel or expansion of the plant as a result of a new or amended Record of Decision for operable unit 6 only upon entering into an agreement with the EPA Administrator or other entity or agency to provide funding for the improvement or expansion.
