On June 24, 2021 the Air Toxics Act (HB21-1189) relating to additional Public Health Protections in Relation to the Emission of Air Toxics was signed into law. This bill creates a new program in CDPHE to regulate toxic air contaminants at four covered facilities, along with a community monitoring program, prioritizing disproportionately impacted (DI) communities, to better protect public health.
Key elements of the bill include a required fenceline monitoring program at each of the following four covered facilities:
- Suncor Refinery, Commerce City
- Phillips 66 Pipeline Terminal, Commerce City
- Sinclair Pipeline Terminal, Henderson
- Collins Aerospace (Goodrich Carbon Product), Pueblo

Community Monitoring
The community monitoring program includes a new state-of-the-art mobile platform called the Colorado Air Toxics (CAT) mobile laboratory, operated by CDPHE. The covered air toxics (hydrogen cyanide, hydrogen sulfide, and benzene) will be measured in communities within a three-mile radius of the covered facilities.
In addition, several ground-based monitoring sites within the sampling regions of the covered facilities will expand the program's monitoring capabilities for the surrounding communities.
