Connecticut adds a new chemical to its list of hazardous air pollutants

Connecticut is updating its air pollution rules to include a new chemical, 1-bromopropane, on its list of hazardous air pollutants. This means facilities in Connecticut that emit this chemical will now face stricter permitting and control requirements.

The US environmental regulators added 1-bromopropane to the federal list of hazardous air pollutants in 2020. States must then update their own rules to match. This change means Connecticut facilities that use or produce this chemical will now have to invest in new equipment or processes to reduce their emissions, or face penalties. It also means the state can now enforce limits on a chemical it previously could not.
