Commitment to Continued Progress
The comprehensive cleanup program at the Bay Shore former MGP site and its related gas operations support facility in Brightwaters is yielding excellent results. Today, the program is primarily in the Operations, Maintenance and Monitoring phase, with most major construction completed.
Current site status - September 2024
On September 16, National Grid began an Interim Remedial Measure (IRM) on Operable Unit 4 (OU-4), 22 Oak Street, following building demolition on the property. The work is expected to be completed Winter 2024.
The IRM cleanup activities include:
- Excavation of MGP-impacted soil to approximately 15 ft below grade.
- Excavating selected areas where deeper contamination is found to 18-19 ft below grade.
- Off-site disposal of MGP-impacted soils and use of clean material for use as backfill.
- Implementation of a Health and Safety Plan and Community Air Monitoring Plan (CAMP) during all ground intrusive activities.
Hotline Number
National Grid is committed to keeping the community informed of any activities at the site. We will continue to post updates on this project website. Please note that the National Grid Hotline for the Bay Shore former MGP site is (631) 348-6250.
BTEX, PAH and Sitewide Progress Videos
We have completed the majority of remedial construction activities at the site. We would like to express our appreciation to all of our neighbors in the TOI for their cooperation and patience during this important project. In 2015, National Grid upgraded the 87 Community Road oxygen injection line to include injection wells in the Long Island Railroad right-of-way and expanded the OU-1 South oxygen injection line across N. Clinton Avenue. The work is intended to target remaining downgradient groundwater impacts. As a result of groundwater concentration reductions, two of six oxygen injection systems in OU-2 were deactivated in March 2015 and removed in May 2017.

NYSDEC Report
During active construction, NYSDEC produced and distributed periodic reports posted on its and National Grid’s websites for the project and e-mailed to residents, with highlights of recent remedial activities and notifications about upcoming work that could affect normal community activities. These reports were suspended at the conclusion of active construction and can be found in the Documents and Resources section of this website.
NYSDEC Fact Sheet
The NYSDEC produced and distributed Fact Sheets at the significant milestones in the project, including when remedial investigation reports were completed, remedial action plans approved and when major construction activities were about to begin. Recently, Fact Sheets have been produced to update the community on overall site status and on-going work in the operable units.
