Respondent is currently performing supplemental investigations at the Ringwood Mines/Landfill Site pursuant to an Administrative Order on Consent and Settlement Agreement for Investigative Work, CERCLA 02-2005-2013, entered into by the Respondent and EPA in September 2005. Certain work remains to be completed which the Respondent was required to do pursuant to the 2005 AOC. That work, including payment to EPA of all unreimbursed EPA response costs, shall now be performed pursuant to Administrative Settlement Agreement and Order on Consent for Remedial Investigation/Feasibility Study.
The AOC requires the preparation and performance of an RI/FS for four areas of concern at the Site: the Peters Mine Pit Area, the Cannon Mine Pit Area, the OÂConnor Disposal Area and the Site-related groundwater contamination.
