CLEAN AIR ACT OVERVIEW National Ambient Air Quality Standards (NAAQS) State Implementation Plans (SIPs) New Source Performance Standards (NSPS) Prevention of Significant Deterioration (PSD) Non-attainment New Source Review (NSR) 2
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 operation of, a stationary source which increases the amount of any air pollutant emitted by such source or which results in the emission of any air pollutant not previously emitted.” 3
AMERICAN ELECTRIC POWER 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 ozone, which was transported from the midwest to non-attainment states in the northeast. 4
AMERICAN ELECTRIC POWER 5
AMERICAN ELECTRIC POWER 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. 6
