    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.
