Gas used for cooking, lighting, heating and commercial purposes was manufactured at the Sag Harbor Manufactured Gas Plant 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 that were released on the site are responsible for contamination which is now being addressed through a Remedial Action Plan and Remedial Design approved by and being conducted under the oversight of the New York State Department of Environmental Conservation by National Grid. The site is owned by National Grid, which is responsible for the investigation and remediation of the site because one of the companies that operated the site was a predecessor of National Grid. Other companies were also responsible at various times for operating the MGP.

This website provides information on the Sag Harbor former MGP Site, the remediation project 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.

Periodically, National Grid will provide activity updates for the neighbors of the Sag Harbor Former MGP Site.  This update will describe work that has been done since the completion of the Remedial Action Work.  This update 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.

Update, Summer 2010

During the summer of 2010, National Grid will be conducting quarterly groundwater sampling per the quarterly groundwater monitoring program.  This sampling event will take place in late June/early July.

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.
