National Grid in Troy, NY is responsible for the investigation and remediation of the former Manufactured Gas Plant (MGP) site located at Hempstead Intersection Street. The plant, which operated from the early 1900s to the mid-1950s, produced gas for cooking, lighting, heating, and commercial purposes using coal and petroleum products. National Grid is committed to minimizing the environmental impacts of their activities and is implementing an approved Remedial Action Plan under the oversight of the New York State Department of Environmental Conservation.
In 2023, National Grid completed the major remedial construction work for the site, and the Final Engineering Report for the remediation work was approved by the NYSDEC in April 2017. Ongoing Operations, Maintenance, and Monitoring (OM&M) activities include routine maintenance of groundwater oxygenation treatment systems and monitoring wells, with one treatment system shut down due to groundwater plume reduction. National Grid submits reports of these activities to NYSDEC for review and can be found in the Key Documents section of their website.
