Clean Air and Building Infrastructure Improvement Act

HR 4214 requires the Environmental Protection Agency (EPA) to publish final implementing regulations and guidance for new or revised national air quality standards at the same time as the standards themselves. This affects developers seeking preconstruction permits for facilities like factories or power plants, as the new standards cannot be applied to permit reviews until the EPA provides this guidance. The bill also includes a specific provision delaying the application of the 2024 PM2.5 air quality standard to certain permit applications if they meet timing conditions related to the EPA's final designation of affected areas. It does not change the air quality standards or pollution limits themselves, but ensures permit applicants receive clear guidance alongside new rules. The bill focuses on procedural timing for EPA rulemaking to streamline the permitting process.
