EPA is working closely with the Town of Montville, Connecticut and the Connecticut Department of Environmental Protection (CTDEP) to supervise the removal of electrical transformers containing polychlorinated biphenyls (PCBs) from the Wisniewski Superfund Site on Route 163 in Montville. The trustees of the Site are undertaking the removal under EPA oversight and have approved to remove all eight transformers and two associated capacitors from the property to a licensed off-site disposal facility.

EPA investigations of the property in November 2007 and January 2008 concluded that some of the transformers contained oil contaminated with PCBs. Testing of the soils in the surrounding area of the transformers did not reveal any PCB contamination above CTDEP’s most stringent residential cleanup criteria. Temporary spill containment will be constructed prior to the removal as a protective measure.

The cleanup is expected to begin within the next several weeks and be finished by the end of the summer. As part of the removal, some additional testing of the transformers will be performed, followed by the removal of the equipment to an EPA-approved treatment and removal facility.
