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.

June 2019

National Grid is preparing to begin field work for the remediation of the former Citizens Works Manufactured Gas Plant (MGP) Site. Remedial activities are expected to begin this summer and take about 20 months to complete. The work will be conducted under the oversight of the NYS Department of Environmental Conservation.

The remedial design for the site was approved by NYSDEC in 2018. Following approval, National Grid has procured contractor and environmental consulting services to perform field construction activities. In addition, earlier this Spring National Grid began working with off-site private property owners to conduct pre-construction surveys of adjacent properties in anticipation of the start of work. NYSDEC held a Public Availability Session on June 13th at PS 372 to review the remediation plan and schedule for the Citizen’s remediation project.

Progress of Work

National Grid will provide routine updates to the website as the construction team mobilizes to the site and the work progresses.
