350 Irving Street Framingham Remediation Project

MEPA Filing Updates

EEA 16576 350 Irving Street Remediation, Framingham

On behalf of NSTAR Electric Company d/b/a Eversource Energy, Epsilon Associates, Inc. is pleased to submit the enclosed Draft Environmental Impact Report (“DEIR”) for the proposed #350 Irving Street Remediation Project in Framingham, MA (the “Project”). The Project proposes to remediate contaminated soil, sediment, and groundwater associated with the operation of a former Manufactured Gas Plant (“MGP”) facility.

The project site is located within an Environmental Justice population. The project meets the threshold for filing an Environmental Impact Report (EIR) at 301 CMR 11.03(3)(a)(1), alteration of one or more acres of BVW. The project requires a 401 Water Quality Certificate and potentially a Chapter 91 dredge permit from the Massachusetts Department of Environmental Protection (MassDEP) and an 8(M) Permit from the Massachusetts Water Resources Authority (MWRA).

The enclosed DEIR builds upon the Environmental Notification Form (“ENF”) that was filed with MEPA in June of last year and provides additional details on the measures that Eversource will undertake to remediate the identified contaminants in accordance with the provisions of the Massachusetts Contingency Plan regulations (310 CMR 40.0000) and other applicable regulations.

The DEIR was noticed in the Environmental Monitor on the MEPA Website on March 8, 2023 and that comments will be due by April 7, 2023.

Why Are We Doing This Project?

The property at 350 Irving Street in Framingham, Massachusetts, was occupied by a former Manufactured Gas Plant (MGP) that operated from 1889 until 1967, producing gas from coal and oil for distribution to homes and businesses in Framingham and surrounding towns.

Portions of the property were impacted by these historical activities, and this project will help clean up those byproducts left behind.

Following implementation, the proposed remediation project will result in substantial environmental benefits and will also make a meaningful and lasting difference to the adjacent property owners and the community in general.

Where Is This Work Being Done?

What Work Is Being Done?

Future remediation will include containment and removal of soil and groundwater contaminants as well as removal of stream sediment within Beaver Brook. A comprehensive Wetland Restoration and Buffer Zone Enhancement Plan will be put into place, and upgrades to the existing stormwater management system will bring these systems up to current MassDEP standards.
