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.
For additional information and history of the program, visit the Cleaner Air Oregon website.

 Risk Assessment is highlighted

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. ​​

Aug. 26, 2019: Facility called in to CAO program.

Nov. 25, 2019: Facility submitted Emissions Inventory

Jan. 23, 2020: DEQ sent comment letter requesting supporting information

Feb. 19, 2020: Facility submitted the following documents in response to DEQ's comment letter:

March 9, 2020: DEQ approves Emissions Inventory

April 12, 2022: DEQ sent letter regarding revised reporting requirements for exempt TEUs

The Modeling Protocol provides information on how the facility plans to accurately model the concentrations of Toxic Air Contaminants (TACs) that community members may be exposed to based on the TAC emissions data from the approved Emissions Inventory. A Risk Assessment Work Plan is required for more complex Risk Assessments (Level 3 or Level 4) and provides more detailed information about locations where people live or normally congregate around the facility and how risk to these community members will be evaluated.​​

  • Approved Risk Assessment Work Plan​

The Risk Assessment provides the summary of findings on potential risks to the surrounding community from emissions of Toxic Air Contaminants from this facility. The assessment indicates the exposure location(s) in the community with the highest potential Cancer and Noncancer health risk, and DEQ uses this information to regulate TAC emissions from the facility. In some cases, the risk may be very low, and no further action may be required, or the risk may exceed health-based standards where DEQ can require risk reductions. In most cases, permit conditions will be developed and included in a facility's air quality permit to regulate TAC emissions based on the results of the risk assessment.

About the Facility

Collins Pine Company (Collins) is a sawmill located in Lakeview, Oregon. Lumber products were manufactured at this location in the mid-1970s under two separate operating permits. In 1989, the permits were combined under one the original Standard Air Contaminant Discharge Permit. Collins produces lumber products by debarking green logs and drying them in kilns. Dried logs are then trimmed, sorted, stacked, and packaged for distribution. Wood waste is combusted in two hogged fuel boilers to create steam for four lumber drying kilns. Emissions from the sawmill and planing mills are controlled by cyclones. Emissions from the two hogged fuel boilers are uncontrolled.
