CLEAN AIR ACT OVERVIEW
PSD & NSR require permits for “construction” of major source of air pollution. “Construction” includes “modification.” “Modification” includes: “Any physical change in, or change in the method of
- peration of, a stationary source which increases the amount
- f any air pollutant emitted by such source or which results
in the emission of any air pollutant not previously emitted.”

Pre-1977 sources exempt from PSD/NSR permitting until “modification” occurs. EPA regulations exclude “routine maintenance, repair and replacement” from “modification.” Midwestern power plant operators claimed all changes to pre-1977 plants were “routine maintenance, repair and replacement.” The result: emissions from these plants generated
- zone, which was transported from the midwest
to non-attainment states in the northeast.

States (including Rhode Island) and others sued under the Clean Air Act. Operator data showed that the plants’ changes were likely “modifications” requiring permits. The result: a settlement worth over $4.6 billion, a significant reduction in emissions from the plants, and ozone improvement in the northeast. Data were key to identifying the path to compliance with the Clean Air Act.
