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.

National Grid’s contractor, Creamer Environmental, has completed remedial actions at the Citizens former Manufactured Gas Plant (MGP) Site to address MGP Site related impacts in accordance with the NY State DEC approved design. National Grid will continue to conduct recovery of NAPL from wells and groundwater monitoring. The cleanup activities were performed with oversight by the New York State Department of Environmental Conservation (NYSDEC).
- The key elements of the completed remediation work include excavation of MGP Site impacted soils and installation of bulkheads using heavy construction equipment.
- Preparation for these key remediation elements requires sheet pile installation to support excavations on site, as well as construction of bulkheads along the Gowanus Canal.
- Installation of monitoring and recovery wells.
- Established measures to reduce potential noise, vibration, and dust from the work including pre-drilling before sheet pile driving and installation of a noise mitigation wall were implemented.
- Air, noise, and vibration monitoring were conducted each day to ensure that the work was conducted in accordance with the requirements of NYSDEC, NYSDOH and NYC.
- Recovering NAPL from wells and groundwater monitoring.
Recently completed activities:
- Final grading and restoration of the Parcel I supplemental excavation.
- Transporting impacted materials off-site for disposal.
- Demobilizing equipment and supplies.
