The New Source Review (NSR) program of the Clean Air Act requires major stationary sources to go through an extensive, time-consuming, and expensive review and permitting process prior to construction. Among other requirements, such sources are required to install the best available control technologies (BACT) to reduce levels of specific regulated pollutants. The NSR program also applies to existing facilities if they are modified in ways that result in significantly increased emissions.

This lack of certainty has significant implications to how sources must evaluate compliance going forward.
