Environmental and health groups are crying foul over proposed changes in Massachusetts regulations concerning wood boilers.
Critics of the proposed new regulations claim it will significantly undermine landmark steps Massachusetts took in 2012 that effectively eliminated biomass fuels from the state’s clean energy portfolio.
Rules adopted under then- Energy Secretary Rick Sullivan followed a study that challenged claims that burning wood is clean energy.
" Its based on the science and the Manomet study," he said.
Proponents of the changes in regulations say it will not worsen pollution.
A public hearing is scheduled Monday in Holyoke.
