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 final delivery of the Deep Soil Mixing (DSM) equipment. On site excavation work continued inside the Temporary Containment Building (TCB) for loading and offsite disposal. From December 22, 2011 thru January 2, 2012 the project will be shut down due to the holidays. Work will resume on January 3, 2012. Work activities for that week will consist of continued soil excavation and completion of the DSM rig set up and testing.

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.
