The Bay Shore MGP began operations in the late 1880s. The plant was operated by Mutual Gas and Light Company, The Suffolk Gas and Electric Light Company and later the Long Island Lighting Company (LILCO) in 1918. LILCO operated the plant from 1918 to approximately 1973 when most of the facilities were demolished. In 1998, KeySpan acquired the former MGP property through a merger of LILCO and Brooklyn Union Gas Company. KeySpan, the immediate predecessor to National Grid, entered into an Order on Consent with the New York State Department of Environmental Conservation (NYSDEC) to conduct a Remedial Investigation and remediation of the site in 1999. In 2007, National Grid acquired KeySpan and is the present owner of the former Manufactured Gas Plant site.

Following completion of the initial phase of the Remedial Investigation (RI), four Operable Units (OUs 1-4) were designated, each of which have unique and separate issues. This permitted the remedial process for OUs 2, 3, and 4 to proceed at an independent pace while the complexities of the main site area (OU-1) were addressed under the RAP process. OU-1 constitutes the main site area. OU-2 is the groundwater plume downgradient of OU-1. OU-3 includes the Brightwaters Yard and associated groundwater plume. OU-4 includes an area east of OU-1 where former process waters were discharged into an industrial cesspool.

This website provides information on the Bay Shore/Brightwaters 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. If you need additional information or have suggestions to make our website better, please contact the individuals listed under Contacts.

During the first two phases of the remediation of the main site (Operable Unit 1) National Grid provided a weekly update on construction activities and progress as well as an outlook on future work. Those update reports are available in the Weekly Reports Archive in the Key Documents section of this website. There is no active work on the main site pending the design of the next elements of that Remedial Action Plan. National Grid will post the Bi-Weekly Updates produced by the New York State Department of Environmental Conservation on this page. NYSDEC Updates will also be posted in the Archive.
