177Violations

A high-priority violation is the most serious class of Clean Air Act non-compliance an agency records against a source; a federally reportable violation is the next step down in severity. Every violation below was recorded against a source in Colorado during 2023; one facility can appear more than once, because this is a record of what happened rather than a list of places.
