NJNG has been actively conducting improvements at three former manufactured gas plant (MGP) properties located in Atlantic Highlands, Long Branch and Toms River, New Jersey. These efforts, under the direction of the New Jersey Department of Environmental Protection (NJDEP), are restoring the former plant properties to productive future use.

There are approximately 3,000 former MGPs nationwide and about 80 in New Jersey. NJNG currently has responsibility for remediation at three MGP sites. NJNG's improvements address, among other things, coal tar residues; a by-product of manufacturing gas from coal and coke that is present in the areas of the former plants.

Potential impacts from MGPs in the state were not subject to environmental regulation until the early 1980s when the state directed utilities of its plan to assess the properties. According to testing conducted on NJNG's behalf, potential risks from contact with coal tar residues at NJNG's MGP properties are within acceptable state and federal health-based risk levels.

NJNG works closely with the NJDEP to ensure compliance with all environmental regulations. When conducting improvements, the safety of the residents and surrounding communities are NJNG's primary consideration. NJNG looks forward to successful completion of these projects for the benefit of our neighbors and communities we serve.
