MTBE – Methyl Tert-butyl Ether (MTBE) is present in concentrations that are over 100 times higher than the state-wide health standard. (Evergreen note: the comment addresses concentrations of MTBE in groundwater).

That is correct.  There are multiple compounds that have been detected in groundwater above statewide health standards (SHSs) at the facility as reported in Remedial Investigation Reports (RIRs).  Methyl Tert-butyl Ether (MTBE), as well as other compounds, that are present above the SHS in groundwater will be evaluated in relation to remedial action in future Act 2 submittals, including Risk Assessment and Cleanup Plans. Some of the interim groundwater remedial systems currently address groundwater with impacts above the SHS, including MTBE, along Site boundaries. These systems along with other remedial measures will be evaluated in future Act 2 submittals.
