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, is implementing 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. Mobilization began on July 10, 2019 and the remedial activities are expected to be completed by the middle of 2021. The cleanup activities are being performed with oversight by the New York State Department of Environmental Conservation (NYSDEC). Community air monitoring and vibration monitoring are being conducted during this project.
- The key elements of the 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.
- There are established measures to reduce potential noise, vibration, and dust from the work including pre-drilling before sheet pile driving, installation of a noise mitigation wall, and the use of temporary enclosed fabric structures with air handling systems to control air emissions from the excavation work within the fabric structure.
- Air, noise, and vibration monitoring are conducted each day to ensure that the work is conducted in accordance with the requirements of NYSDEC, NYSDOH and NYC.
- Excavation of fourth phase of Parcel 1 soil remediation area
- Transportation of materials off-site for disposal and recycling
Recently completed activities:
- Relocation of temporary membrane structure to fourth phase of Parcel 1 soil remediation area
- Backfilling of third phase of Parcel 1 soil remediation area
Upcoming work activities:
- Installation of support of excavation bracing for fourth phase of Parcel 1 soil remediation area
