Important public comment period for the Lower Neponset River Superfund Site begins June 13, 2025
BOSTON (June 13, 2025) – Today, Environmental Protection Agency (EPA) announced the start of a public comment period for the Engineering Evaluation/Cost Analysis (EE/CA) for the Lower Neponset River Superfund Site. This draft report evaluates cleanup alternatives and presents EPA's recommended cleanup plan to address the harmful contamination of Polychlorinated Biphenyls (PCBs) and other hazardous substances from the first mile of the Site.
"This is a milestone moment for the removal of PCBs from the Lower Neponset River and an optimal opportunity for community input," said EPA New England Regional Administrator Mark Sanborn. "The foundation of success at Superfund Sites is facilitating community participation during the decision-making process."
This covers the area of the Neponset River from its confluence with the Mother Brook near the Dana Avenue Bridge to the Tileston and Hollingsworth Dam – a highly populated area.
EPA invites public comment on the alternatives evaluated in the EE/CA and EPA's recommended cleanup plan. EPA will hold a 30-day public comment period, from June 13, 2025, to July 13, 2025.
To review the draft EE/CA report and provide written comment, go to: https://www.regulations.gov/docket/EPA-R01-SFUND-2025-0083. Written comments may also be provided via email or by mail. All public comments on the EE/CA must be postmarked by 11:59PM on July 13, 2025, and should include the Docket ID No. EPA-R01-SFUND-2025-0083.
In addition, a virtual public hearing will be held July 9, 2025, at 6:30 p.m., during which EPA will accept oral public comments. A link to register for the Zoom public hearing, can be found at: https://www.epa.gov/neponsetriver.
Before making a final decision regarding cleanup, EPA will review and consider all public input received during this comment period. EPA will respond to all significant public comments in a responsiveness summary, which will be issued with EPA's cleanup decision.
