Excavation in Temporary Containment Building

National Grid’s contractor (Entact LLC) started mobilizing for the In-Situ Solidification remediation phase for the Hempstead former Manufactured Gas Plant site on October 3, 2011. The latest site activities have included the delivery and set up/assembly of the Deep Soil Mixing (DSM) mounting pads and associated mixing towers and equipment. On site excavation work started inside the Temporary

Containment Building (TCB) for loading and offsite disposal. Over the next two weeks, work will continue on the set up and assembly of the DSM rig, batch plant and other associated equipment. Excavation work will continue with increased trucking quantity for offsite disposal.

A Fact Sheet summarizing the project and potential impacts to the community was previously sent to the community to summarize the work. The Fact Sheet and the finalized Remedial Action Work Plan can also be found in the Key Documents/Major Reports section of this website. A link to the Fact Sheet can be found below.

As work proceeds, the web site will be updated periodically to ensure the community is informed of the project progress and schedule.
