Gas used for cooking, lighting, heating and commercial purposes was manufactured at the Hempstead Intersection Street Manufactured Gas Plant from early 1900’s to mid 1950’s. This plant used coal and petroleum products to create a flammable gas which was piped into the surrounding communities. The production and storage facilities were decommissioned and demolished in the early 1950’s. The by-products of gas production and storage that resulted from site operations are now being addressed through Interim Remedial measures and a Remedial Action Plan approved and being implemented by National Grid under the oversight of the New York State Department of Environmental Conservation. The site is owned by National Grid, which is responsible for the investigation and remediation of the site because it was operated by a predecessor company at the time the contamination occurred.
This website provides information on Hempstead Intersection Street former MGP Site, the remediation projects and opportunities for public participation. National Grid is committed to the protection and enhancement of the environment, always seeking ways to minimize the environmental impacts of our past, present and future activities. We hope this website, a part of our public participation and outreach efforts, is helpful and informative.

The latest site activities include continued pre-clearing of piping and debris prior to In-Situ Solidification (ISS) activities. The # 2 batch plant and the second drill rig assembly have been completed and the #2 drill rig will be shake-down tested prior to using it for full scale ISS production. The temporary containment structure was relocated to the next position for soil excavation and off-site disposal.
A Spring 2012 Project Update Fact Sheet was mailed out to the Community to provide a project schedule update and a summary of the ongoing remediation work. This 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. The work is being performed in accordance with the Community Air Monitoring Plan that was reviewed by the New York State Department of Environmental Conservation, New York State Department of Health and the Nassau County Department of Health. There is an on-site NYSDEC representative monitoring the project activities.
As work proceeds, the web site will be updated periodically to ensure the community is informed of the project progress and schedule.
