Let the People Speak: Notice-and-Comment Rulemaking (Lessons From the Controversial New Source Review Proposal of the Clean Air Act)
Sections 165 and 173 of the CAA specifically note that any change in pollution levels from an existing source triggers NSR and accompanying technological upgrades. Nothing in the rulemaking's proposed definition based on cost of changes or maintenance address this clear language of Congress. --Victor B. Flatt, A.L.
