Citizens former Manufactured
Gas Plant Site

Gas used for cooking, lighting, heating and commercial purposes was manufactured at the Citizens Manufactured Gas Plant from the 1860’s to the early 1960’s. The plant was built by the Citizens Gas Company, and sold to Brooklyn Union, a predecessor of National Grid, in 1895. It used coal and petroleum products to create a flammable gas which was piped to users in the surrounding neighborhoods. The production and storage facilities were decommissioned and demolished in the early 1960’s, and Brooklyn Union sold the site in 1969, after which it had no control of anything that happened on the property. The by-products of gas production and storage that resulted from site operations will be addressed through a Remedial Plan being implemented by National Grid with oversight of the New York State Department of Environmental Conservation (NYSDEC).  Most of the site is owned by the City of New York, with the balance owned by private companies. National Grid is responsible for the investigation and remediation of the site because it was operated by a predecessor company at the time the contamination occurred. 

This website provides information on the Citizens former MGP Site, the remediation projects and opportunities for public participation. National Grid is committed to the protection and enhancement of the environment, always seeking ways to minimize the environmental impacts of our past, present and future activities. We hope this website, a part of our public participation and outreach efforts, is helpful and informative.

Current Site Status

In March 2016, National Grid and its contractors completed additional pilot testing work at the former Citizens Manufactured Gas Plant (MGP) Site under direction of the New York State Department of Environmental Conservation. The work involved testing sheet pile driving on various locations on the site. The NYSDEC-approved Supplemental Design Investigation (see Key Documents tab) was completed and the remedial design for the site was completed and approved by NYSDEC in early 2018.

National Grid remains committed to keeping the community informed of our activities at the former Citizens MGP site and we appreciate your patience and cooperation.
