Quick context to catch up fast.
The committee reviewed a proposed 2026–2027 permit change that would combine excavation levels closer to Swampscott Road and allow up to 10 80-foot blasts in the fall. Members also agreed that air-quality and dust testing should follow clearly stated permit requirements and occur during the permit period.

Your feedback helps us prioritize what to improve next.
The proposed excavation changes could affect noise and nearby residents during blasting, but the committee did not make a final permit decision. The committee will review comments, past heavy-metal test results, and testing requirements before providing recommendations to the Select Board. Future discussions will also consider seismograph placement and whether an air-quality sensor could be located on Amrize property.
