About the Hempstead Intersection Street former Manufactured Gas Plant Site

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.
