Annual reports
In 2024, Colorado adopted Senate Bill 24-229: Ozone Mitigation Measures. Certain parts of the law apply to the CDPHE Air Pollution Control Division. The law requires the division to publish Air Quality Enforcement Reports. The first report, the Air Quality Enforcement Benchmark Report, covers five federal fiscal years from Oct. 1, 2018 through Sept. 30, 2023. Starting in 2025, the division will publish an annual summary of air quality enforcement for the previous federal fiscal year.
- Air Quality Enforcement Benchmark Report: October 2018-September 2023.
- Spanish Air Quality Enforcement Benchmark Report: October 2018-September 2023.
Quarterly reporting
To provide communities with easy access to enforcement documents, the division publishes finalized enforcement settlements every quarter.
