Air Toxics Emissions Reporting

Air Toxics Emissions Reporting Overview

In March 2023, the Oregon Department of Environmental Quality announced the requirement to report a 2023 Air Toxics Emissions Inventory to Air Quality-permitted sources holding a Title V or ACDP Standard or Simple permit. The 2023 Air Toxics Emissions Inventory will be due in the second quarter (Q2) of 2024.  

Individual, facility-wide emissions reports for the 2016 and 2020 Air Toxics Inventories are now available through the DEQ AQ Permits Online webpage. The available Air Toxics Emissions reports have been reviewed by DEQ and, in many cases, facilities were contacted to clarify content or provide more information. If DEQ requires revisions from a facility, an updated report will be re-posted.

The available reports provide a snapshot of estimated facility emissions for the reporting years 2016 and 2020. Emissions from routine processes are combined with those resulting from material usage to estimate facility-wide emissions. The wide variation in emissions across all facilities reflects the differences in size and complexity of sources, equipment and fuel type, control device usage and efficiency, as well as available supporting data.

Note that this periodic, state-wide Air Toxics Emissions Inventory is a separate reporting requirement than an Emissions Inventory submitted as part of the Cleaner Air Oregon risk assessment process.

Visit the 'For Facilities' section of the Cleaner Air Oregon website for more information about conducting a risk assessment.
