The Air Pollution Control Division is reviewing all available toxic air contaminant annual emission data reported from facilities across Colorado. The division is analyzing this data for gaps. The division will summarize this analysis in a report for the Air Quality Control Commission. This report is required before the division  proposes any changes to toxic air contaminant reporting requirements created under a 2022 state law: Public Protections from Toxic Air Contaminants.

Background 

On June 2, 2022, Public Protections from Toxic Air Contaminants (HB22-1244) was signed into law. This law requires rulemaking actions by the Air Quality Control Commission to:

  1. Receive a report from the division to identify gaps in toxic air contaminant reporting.
  2. Based on this analysis, consider changes to the toxic air contaminant reporting requirements, beginning with calendar year 2025 emissions.

The law requires the division to conduct public outreach on this gap analysis report. In particular, the law requires the division to conduct outreach to disproportionately impacted communities and workers at stationary sources.

The law also requires that a formal written public comment period before the division sends this report to the Air Quality Control Commission.

Additional information regarding toxic air contaminant reporting in Colorado is available on the toxic air contaminants reporting website.
