    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 in the final phase of major construction.

    The last major remedial measures are a soil excavation in OU-4 and the installation of two additional oxygen injection lines in OU-2. All other aspects of the overall project have moved into the operation, maintenance and monitoring phase.

    Current Operable Unit 4 Remedial Progress for February 2012

    We have completed the majority of remedial construction activities at the site. The TOI/LIRR parking lot is completely restored and is open to the public. 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 December 2011, we completed asbestos abatement of the former structures at 1627 Union Boulevard (Phase III). Subsequently, National Grid’s Demolition Contractor, Gramercy, demolished the structures and foundations. All building debris has been removed from the site and the building foundations have been backfilled.

    In January 2012, Posillico, National Grid’s Remediation Contractor, completed electrical work and footing installation for light poles on the south side of Oak Street.
