| Date TMDL Approved by USEPA: |
An alternative enforceable program, which is the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), is in place that will address metals and other acid mine drainage associated with the exceedance of water quality standards for this water segment. In May 2000, the USEPA placed the Leviathan mine on the CERCLA National Priorities List (NPL), thus making Leviathan mine a Superfund site. The cleanup process at Leviathan mine is required to meet all environmental requirements, or ARARs (applicable or relevant and appropriate requirements) during its operation. The Leviathan mine is in the Remedial Investigation/Feasibility Study stage of the CERCLA process. A Record of Decision is expected in 2010. |
