Background

- Receive a report from the division to identify gaps in toxic air contaminant reporting.
- Based on this analysis, consider changes to the toxic air contaminant reporting requirements, beginning with calendar year 2025 emissions.
Additional information regarding toxic air contaminant reporting in Colorado is available on the toxic air contaminants reporting website.
