Hazardous Waste Cleanup: Bettis Atomic Power Laboratory in West Mifflin, Pennsylvania

Cleanup Status

Effective October 8, 2010, the remedy for the Bettis facility that was described in the October 1997 Final Decision and Response to Comments is complete. On September 8, 2010, EPA submitted a supplemental Statement of Basis that proposed the substitution of an institutional control in lieu of the only incomplete remedial component from the 1997 Final Decision and Response to Comments (FDRTC) (collection/treatment of Inactive Waste Site seepage). This new institutional control became effective October 8, 2010 and includes monitoring an off-site property for the absence or presence of water supply wells.
