HR 4214

The Clean Air and Building Infrastructure Improvement Act requires the Environmental Protection Agency (EPA) to provide clear guidance and regulations alongside any new or revised national air quality standards. Specifically, it mandates that the EPA publish detailed information to assist states, permitting authorities, and applicants in understanding and complying with these standards, particularly regarding preconstruction permits. The bill also establishes a process where a new air quality standard won’t apply to a preconstruction permit application until the EPA provides implementing guidance, and it includes provisions related to particulate matter standards and emission control technologies.
