Air Toxics Emissions Reporting

The Oregon Department of Environmental Quality is requiring permitted facilities to submit a periodic state-wide Air Toxics Emissions Inventory for the 2023 operating year, reflecting operations from Jan. 1 through Dec. 31, 2023 [OAR 340-245-0040(2)]. Emissions inventories for Air Quality-permitted sources holding a Title V or ACDP Standard or Simple permit are due July 1, 2024.  

The 2023 Air Toxics Emissions Inventory reporting window is open April 1, 2024 to July 1, 2024. Reporting details, forms, instructional documents, and tools are available below. Refer to the Air Toxics Reporting Background page to learn more about this history of this reporting event and available data.

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

Sign up here and select 'Air Toxics Emissions Inventory' to receive GovDelivery email announcements regarding website updates, reporting dates, availability of forms and additional reporting instructions. 

Contact your DEQ permitting office to confirm that your facility's contact information is up to date.

Facilities located in Lane County should communicate directly with Lane Regional Air Protection Agency staff with questions regarding submitted reports.
