Cleaner Air Oregon 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 DEQ's communications and deliverables from the facility.
- The graphic below shows where a facility is in the Cleaner Air Oregon Process.

About the facility
The Stimson Lumber Company presently houses a saw mill, a planer mill and a wet process hardboard mill. The sawmill and planer mill produce 6' to 10' premium studs for retail markets out of Douglas-fir and Hemlock logs. Most of the logs are supplied from the 472 acre-forest land adjacent to the mill, although Stimson owns half a million acres of forest land throughout the Pacific Northwest. The hardboard plant utilizes the Douglas-fir sawdust and wood chips from the saw mill and presses it into a high density panel used for retail and industrial uses. The finished lumber and hardboard can be shipped to market via trucks or rail (specifically by Portland & Western Railroad, which connects to Union Pacific Railroad). The mill offers loading for center beam cars, maxi trucks, flatbed trucks and vans.
