Frequently Asked Questions
What are PCBs?
PCBs, or polychlorinated biphenyls, are a class of chemicals consisting of 209 individual compounds. PCBs were widely used as a fire preventive and insulator in the manufacture of transformers and capacitors because of their ability to withstand exceptionally high temperatures.

How did the PCBs get in the Hudson?
Beginning in the 1940s, GE used PCBs as an insulating fluid in electrical capacitors manufactured at plants along the river in Hudson Falls and Fort Edward, N.Y. GE discontinued its use of PCBs in 1977. When they were used, PCBs were discharged to the river in the plants' waste streams, a common practice then. GE held the proper government permit to discharge PCBs to the river at all times required.
Most of the material that was discharged to the Upper Hudson, including PCBs, accumulated behind a dam in Fort Edward, south of GE's Fort Edward plant. In 1973, the owner of the dam demolished it and the material that had built up behind it washed downstream, settling in river sediments.
In 1983, at the behest of New York State, EPA evaluated river conditions. After a careful examination of the river's conditions and a review of existing remedial technologies, EPA rejected dredging in 1984. EPA began a re-evaluation of its decision in 1989, leading to its selection of dredging for the river in 2002.
What has GE done to clean up the company's manufacturing facilities on the Hudson River?
GE has been working with the New York State Department of Environmental Conservation and the Environmental Protection Agency for more than 30 years to clean up PCBs at its Hudson Falls and Fort Edward facilities. For more information, click here.
Where is the processing, treatment and transportation facility located?
The facility is on a parcel in Fort Edward, NY, that sits between the New York State Champlain Canal and a main line of the Canadian Pacific Railway. The wharf of the facility is about a mile north of Lock 7 on the Canal. For more information on the facility, click here.
Was local labor used on the project?
More than 210 local contractors, sub-contractors, vendors and suppliers were engaged to provide services or materials to assist on the dredging project. For a list of businesses, click here.
