Air toxics: emissions reporting

Thousands of facilities in Colorado are required to report air toxics emissions to a variety of state and federal programs. Reported emissions provide facility-specific information that can be evaluated – along with monitoring data and community exposures – to assess areas that may have higher health risks. This information helps public health agencies prioritize strategies to reduce air toxics in these areas.

On June 2, 2022, HB22-1244 (Public Protections From Toxic Air Contaminants) was signed into law. HB22-1244 requires larger stationary air pollution sources, specifically sources required to obtain an operating permit and synthetic minor sources, to report their first facility-wide emissions of toxic air pollutants by June 30, 2024. 

CDPHE will consult with stakeholders to develop a report to analyze the initial air toxics reporting requirements and identify any gaps in reporting. The department will present this report to the Air Quality Control Commission by October 1, 2024. The commission may revise air toxics reporting requirements by April 2025 for subsequent reports after assessing any gaps identified in the initial reporting years.
