About the Metropolitan former Manufactured Gas Plant Site

Gas used for cooking, lighting, heating and commercial purposes was manufactured and distributed at the Metropolitan Manufactured Gas Plant. A predecessor to the Brooklyn Union Gas Company began operating the Metropolitan site as an MGP in 1871. By 1904 the Brooklyn Union Gas company was operating the site.  The medium-sized facility produced gas until the 1930’s, at which time it was decommissioned and the site became used for storage. By the late 1940’s portions of the site had been subdivided and various parcels sold, and the remainder of the site was sold in the 1950’s.

The 7.8 acre site has multiple parcels and owners, with the largest parcel having been developed as a Pathmark supermarket.  The eastern portion of the site was investigated under a Voluntary Clean-Up agreement by its then owner, the U.S. Postal Service, and subsequently developed into a Lowe’s store. All of the site is developed, either with buildings or paved parking lots.   National Grid has no liability with regard to the eastern portion of the site, but does for its western and southern portions. National Grid is responsible for the investigation and remediation of these portions of the site because it was operated by a predecessor company (Brooklyn Union) during the time MGP-related contamination occurred.

Current Site Status

In March 2017, National Grid and its contractor conducted supplemental field work at the former Metropolitan MGP site.  The work took place inside the Hamilton Plaza Shopping Center in the location of the former Pathmark Supermarket.

The purpose of the field work was to determine if any contamination exists underground at the site and, if so, evaluate its distribution. Previous field work has found there is no contamination related to the former MGP operations at the ground surface. The New York State Department of Environmental Conservation (DEC) has stated that people at the site are not expected to come in contact with contaminants associated with the former MGP.

During the work period of about six weeks, National Grid’s the contractor took samples from 15 soil borings. The work was completed as part of an approved Supplemental Remedial Investigation under the direction of the DEC.  A report of the results is expected in approximately 4 months and will be posted to this website.

National Grid is committed to keeping the community informed of our activities during this work.  We will continue to post updates online. Any questions can be posed by calling National Grid’s Hotline for the former Metropolitan MGP Site at (718) 982-7349.

Remedial Investigation field work commenced in late-March at the former Metropolitan Works MGP as part of the New York State Department of Environmental Conservation (NYSDEC)-approved Remedial Investigation Work Plan (RIWP).  The work includes the installation of soil borings, monitoring wells, test pit excavations, and indoor air and sub-slab soil vapor points to gather information required to determine the nature and extent of impacts at the former Metropolitan Works MGP.
