Established in 1936, the Interstate Environmental
Commission is a tri-state water and air pollution control agency for New
York, New Jersey, and Connecticut.
The mission of the IEC is to protect and enhance environmental quality
through cooperation, regulation, and communication between government
officials and citizens in the tri-state region.
The Interstate Environmental Commission is the oldest regulatory and
enforcement agency in the region, and clearly, year in and year out, the
Commission’s track record of accomplishments benefitting New York, New
Jersey, and Connecticut speaks for itself.
