Where it stands as of Tue, Jun 9
Resident complaints regarding odor and early-morning noise from the Brox Industries asphalt plant in Marlborough remain under state oversight, as Town Counsel confirmed Southborough lacks regulatory jurisdiction over the facility. Although Brox installed a closed-loop exhaust mitigation system and MassDEP determined emissions meet federal standards with no known direct health threat, Southborough neighbors continue to report persistent odors. Southborough health officials are tracking local reports and urging residents to submit detailed real-time logs directly to MassDEP to assist state regulators.
- Against Public comment A Stow Road resident reported persistent chemical odors and early-morning noise, requesting that Southborough and Marlborough jointly fund an independent air quality consultant to test for toxins.

Brox asphalt plant odor and mitigation follow-up
Health department staff and board members reported on a recent informational meeting with the Massachusetts Department of Environmental Protection, Marlborough Board of Health, Brox plant leadership, and local residents concerning persistent asphalt odor complaints. Brox recently installed a closed-loop system intended to cycle exhaust back into the burner, in addition to existing EcoSorb and mister systems, though Southborough residents continue to report odors. MassDEP reported that existing emissions testing meets federal standards and that current operations pose no known health hazard, but officials stressed that residents must submit detailed real-time logs to help identify operational patterns.
- Brox installed a closed-loop burner exhaust system before Memorial Day weekend to mitigate odor
- A similar mitigation system in Ipswich reportedly reduced resident complaints from 165 down to zero
- MassDEP confirmed Brox operates within state and EPA permit standards and poses no known direct health threat
- Residents are requested to log specific odor descriptors, intensity levels, durations, and symptoms directly to MassDEP
Outcome: Discussion only; health staff will continue sharing state data and tracking resident reports
