Connecticut must now enforce stricter air quality rules for ozone pollution

The US environmental regulators are approving Connecticut's plan to update its air quality rules. This means more industrial sources in the state will now have to meet stricter pollution limits for ozone, because the definition of a "severe non-attainment area" changed.

For years, some industrial facilities in Connecticut were not subject to the strictest air pollution rules. This change means they now are. It forces these facilities to either reduce their ozone-forming emissions or face penalties, which could lead to cleaner air in the region.
