Air Toxics Emissions Reporting

Air Toxics Emissions Reporting Overview

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 will be due July 1, 2024.  

The 2023 Air Toxics Emissions Inventory reporting window will be open April 1, 2024 to July 1, 2024. DEQ will post additional reporting details, forms, instructional documents, and tools to this page as they become available in advance of the reporting window. Refer to the 2020 ATEI Emissions Inventory Reporting Form below for a preview of the 2023 reporting format.

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.

Notice of Intent to Construct

Some unpermitted and permitted facilities which are required to submit a Notice to Construct AQ104 form must also submit an AQ104B Toxics Reporting form if proposed construction will increase toxics emissions in any way.
