Public protections from toxic air contaminants

On June 2, 2022, Public Protections from Toxic Air Contaminants (House Bill 22-1244) was signed into law. This law creates a new program in CDPHE to regulate toxic air contaminants.

Key elements of the law include:

• Creation of an air toxics monitoring program.
• A requirement for certain sources of air pollution to submit annual toxic air contaminant emission reports.
• A requirement for the Air Pollution Control Division to conduct a needs assessment for administration of an air toxics permitting program.

The law also directs the Air Quality Control Commission to:

• Evaluate gaps in air toxics reporting.
• Consider revisions to an air toxics reporting program.
• Identify priority air toxics.
  • For each priority air toxic:
    • Establish health-based standards for General Assembly Approval.
    • Develop emission control regulations.

HB22-1244 required the Air Pollution Control Division to post an initial list of covered toxic air contaminants by October 1, 2022.  The latest list of Toxic Air Contaminants is available online:
