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.

The Emissions Inventory provides information on all the Toxic Air Contaminant emissions from a facility, and includes information on a facility's operations and activities, as well as fuel and material usage rates. This is often the longest step in the CAO risk assessment process as DEQ needs to verify that all activities have been accounted for, and that the most representative emissions data available are used. In some cases, DEQ will require a facility to perform source testing at this stage if insufficient data is available to estimate emissions. For an introduction to emissions inventories and why they matter, please see EPA's fact sheet​

About the Facility

Hampton Lumber Mills, Inc., dba Tillamook Lumber Company operates a saw mill at 3111 East 3rd Street in Tillamook, Oregon. Logs are brought into the log yard by truck and are mostly hemlock. The logs are debarked and sawed to specifications for the lumber product. Most of the lumber is dried in the drying kilns prior to shipment. The kilns are heated by steam supplied by a hog fueled boiler. Wood residue generated from wood working operations includes sawdust, wood chips, wood shavings and bark. Part of the wood residue (i.e., bark, some shavings, and some sawdust) is used as fuel for the hogged fuel boiler. The remainder (e.g., wood shavings and chips) is transported for market. Some lumber may be anti-stained coated or painted with the company logo and have end-seal applied prior to shipment.
