# SUPPLEMENTARY INFORMATION:

The proposed Settlement Agreement is for the performance of a removal action by the Settling Party and the payment of certain response costs incurred by the United States. This Settlement supersedes and replaces in its entirety, and, as of the Effective Date, terminates the Unilateral Administrative Order for Removal Action, docket number CERCLA-08-2011-0005 (UAO) that EPA issued to the Settling Party on March 17, 2011, under which Respondent has implemented certain response actions, including addressing settling ponds and constructing a pilot water treatment system to treat acid mine drainage coming from the St. Louis Tunnel. The purpose of this Settlement is to provide for: Settling Party's payment of certain past response costs, as well as design, construction, operation, and monitoring of a full-scale water treatment system to remove hazardous substances from the St. Louis Tunnel discharge, hydraulic control measures for the collapsed St. Louis Tunnel adit, and solids management facilities; and EPA's oversight of the implementation of such Work at the Site. The Settling Party consents to and will not contest the authority of the United States to enter into the Agreement or to implement or enforce its terms. The Settling Party recognizes that the Agreement has been negotiated in good faith and that the Agreement is entered into without the admission or adjudication of any issue of fact or law.

Division Director, Superfund and Emergency Management Division, Environmental Protection Agency, Region VIII.
