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.
- Transportation of materials off-site for disposal and recycling
- Installation and backfilling of Parcel 3 bulkhead tie back system
- Backfilling second phase of Parcel 1 soil remediation area
- Installation of Parcel 3 hydraulic relief system
Recently completed activities:
- Excavation of second phase of Parcel 1 soil remediation area
- Installation of Parcel 3 bulkhead closure sheet
Upcoming work activities:
- Installation of Parcel 2 hydraulic relief system
Community Air Monitoring Plan Summary
Continued community air monitoring. For the period 10/15/20 through 10/21/20 there were no levels above the 15-minute Action Limit for Total Volatile Organic Compounds (TVOC). On 10/21/20, there was one 15-minute level above the Action Limit for Particulate Matter (PM-10) [smoke from welding adjacent to gas shaft] within the eastern Site boundary along the Gowanus canal. The welding activity was limited and was stopped when the Action Level alert was received. Welding operations were reconfigured prior to resuming activities. Additionally, no dust was observed leaving the Site during this period. No additional levels above the 15-minute Action Limit for PM-10 occurred during the reporting period.
Backfilling second phase of Parcel 1 soil remediation area.
Installation of Parcel 3 hydraulic relief piping.
