Council hears options as PFAS and DEP phasing complicate sludge disposal; landfill expansion debated

Speaker 3 briefed the council on the project's draft environmental review and said comments from the Department of Environmental Protection require phasing of the site work, a step that could force repeated review and create financial risk if later permits are withheld. Speaker 3 told the meeting that phasing is problematic because the site's topography means much of the earthwork needs to be done up-front and phasing could be "fiscally undoable."

Sludge disposal pressures: Speaker 2 described a statewide challenge: municipalities are running out of places to ship sludge, some states are reducing or refusing shipments, and PFAS contamination is driving costs and limiting options. Speaker 2 warned that hauling costs are "completely variable" and that Massachusetts has not adopted a comprehensive long-term disposal plan.

Options on the table: staff said the city could expand the landfill (buying roughly 20 years of capacity, in the speakers' view) or haul sludge farther away; another potential option is the Fitchburg anaerobic digestion plant if it becomes operational. Speaker 3 summarized DEP guidance and local analysis by saying, "reports from DEP even state that currently, landfilling is the best option." Councilors expressed concern that expansion would be a temporary solution and that spending on expansion could later prove wasteful if technology or regional capacity changes.

Next steps: staff plan to continue evaluating options, track Fitchburg plant developments, and present financial feasibility analyses before asking the council to decide on landfill expansion or alternative disposal strategies.
