Cleaner Air Oregon ProfileHexion, Inc.
Cleaner Air Oregon (CAO) is a health-based permitting program that regulates emissions of toxic air contaminants from facilities based on risk to nearby communities. CAO requires facilities to report toxic air contaminant emissions, assess potential health risks to people nearby and reduce toxic air contaminant risk if it exceeds legal limits.
As part of the Cleaner Air Oregon process, each facility has a dedicated web page to provide communities access to facility information and updates on where it is involved in the process.
- Each step of the CAO risk assessment process has a section that includes LRAPA’s communications and deliverables from the facility.
- A color-coded graphic shows where a facility is in the Cleaner Air Oregon Process.
- For additional information and history of the program, visit the DEQÂ Cleaner Air Oregon website.

Modeling Protocol & Risk Assessment
This section will be updated when the facility submits a modeling protocol and risk assessment work plan for approval and then completes a risk assessment. The risk assessment calculates the risk posed to the community by the facility’s air emissions.
Risk Assessment Report
This section will be updated when the facility submits a risk assessment report presenting the results of modeling and calculating health risks from the facility. The risk assessment report undergoes public review.
Risk Reduction Plan
If modeling shows elevated risks, this section will be updated when the facility submits a plan to install pollution controls or take other actions to reduce risks below Cleaner Air Oregon benchmarks. The risk reduction plan undergoes public review.
CAO Progress Completed
This section will be updated when the facility completes all Cleaner Air Oregon requirements, including required emissions reductions and permitting actions. The facility’s updated permit will ensure ongoing compliance.
