Gas used for cooking, lighting, heating and commercial purposes was manufactured at the Sag Harbor Manufactured beginning as early as the 1860’s and continued to the late 1920’s, after which the facility was used exclusively for gas storage and gas distribution. The by-products of gas production and storage that spilled, leaked, or were disposed on the site are responsible for contamination which has been addressed through a Remedial Action Plan, Remedial Design and Remedial Construction approved and conducted with the oversight of the New York State Department of Environmental Conservation by National Grid. The site is owned by National Grid, which was responsible for the investigation and remediation of the site because it was operated by a predecessor company at the time the contamination occurred.

This website provides information on the Sag Harbor former MGP Site, its history, the remedial investigation and the remediation projects. 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.

National Grid will provide activity updates as developments warrant for the neighbors of the Sag Harbor Former MGP Site. The updates will describe work that has been done since the completion of the Remedial Action Work. Updates will include upcoming work, and information about any work that may impact normal community activities. The Archive section of this website will include all of the past Weekly Updates and the periodic submissions.

National Grid conducts quarterly groundwater sampling per the quarterly groundwater monitoring program in the Record of Decision. The reports are placed on the website (Major Reports) and in the Document Repository. National Grid will also be submitting a Draft Construction Completion Report and finalizing a Site Management Plan for the former Sag Harbor MGP Site. The Site Management Plan, once finalized and approved by the NYSDEC and NYSDOH, will be implemented on National Grid property and the adjoining areas and residences.
