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. Each row is one violation recorded during 2021 at a Colorado source whose primary industry code is NAICS 2123. A facility filing more than one industry code is counted under the first one on its record.
