Seneca Sawmill Company
Cleaner Air Oregon ProfileSeneca Sawmill Company
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 DEQ Cleaner Air Oregon website.
