2020 Air Toxics Emissions Reporting Overview

The Oregon Department of Environmental Quality requires permitted facilities to submit air toxics emissions inventories (ATEI) for the calendar-operating year from Jan. 1 through Dec. 31, 2020 [OAR 340-245-0040(2)]. DEQ recognizes that emissions reported for 2020 may not be representative of 'normal' year operations for some facilities; however, because the data is used for the National Emissions Inventory, it is important to capture this fluctuation despite any anomalous activities. Over the course of the 2020 calendar year, facilities should have monitored and recorded their operating activity and material usage in preparation for reporting to DEQ in the third quarter of 2021. Facilities in Lane County will report directly to the Lane Regional Air Protection Agency. Refer to the 'Who Should Report' section below for updated information. DEQ will post additional reporting details, forms, instructional documents, and tools to this page as they become available.

The 2020 Air Toxics Reporting Quick Guide provides a printable overview of updated reporting requirements. Additional information is available on the Air Toxics Emissions Reporting Frequently Asked Questions page.


All Title V, Standard and Simple ACDP permitted facilities operating in Oregon are required to report to DEQ (or LRAPA) their 2020 operations and activities related to toxic air contaminant emissions. Find a reporting overview in the 2020 Air Toxics Reporting Quick Guide.

For 2020, all General ACDP, Basic ACDP, and Area Source Registration permit-holders are excused from this air toxics reporting requirement.  Refer to the Air Toxics Emissions Reporting FAQ for more information. ​

Title V, Standard and Simple ACDP permitted facilities must report their toxic air contaminant emissions inventory for calendar year 2020 to DEQ (or LRAPA) by Sep. 1, 2021. Additional information, including online submission instructions, will be available in the Spring of 2021.   

Anticipated timeline:

  • April, 2021 - Sources receive formal notification of reporting requirement
  • May, 2021 - Reporting form, Emissions Inventory Tools, and Recommended Procedures document are available to download
  • June, 2021 - AQ Document Upload Application launches for facilities to submit completed ATEI reporting forms
  • Sep. 1, 2021 - Deadline for sources to electronically submit their completed ATEI form to DEQ

Title V, Standard and Simple ACDP permittees are required to estimate their air toxics emissions for 2020. This includes the following information, as applicable:

  • Identification of toxics emissions units (EUs)
  • Annual production activities and fuel usages by EU
  • Identification of Toxic Air Contaminants by EU
  • Identification of emission factors by EU, associated reference information
  • Annual material usage, waste shipped offsite of air-toxics containing materials
  • Material information found on Safety Data Sheets
  • Identification of control devices and control efficiencies by EU
To the extent possible, facility and emission unit information should appear the same as on the source's Permit or the most recent Permit modification. A printable reporting overview is available in the updated 2020 Toxic Air Contaminant Reporting Quick Guide.

A list of Oregon's 600+ toxic air contaminants, including EPA's 187 hazardous air pollutants (HAPs), can be found on the Toxic Air Contaminant Reporting List (OAR 340-245-8020 Table 2). This information will also be provided in the reporting form.

Operations and activities that may be omitted can be found in the list of Categorically Insignificant Activities to Exclude [OAR 340-200-0020(23)]. Refer to the FAQ page for more information. 

A comprehensive Air Toxics Emissions Inventory Recommended Procedures document is in development, along with Emission Factor Search Tools, and a Material Balance Calculator Tool. Additional information about these resources can be found on the Air Toxics Reporting FAQ page.

DEQ will provide a standardized, Excel-based (.xlsx) 2020 Air Toxics Emissions Inventory (ATEI) reporting form for facilities. The form will be available to download in May 2021. Additional information about the ATEI reporting form is available on the Air Toxics Reporting FAQ page.

Some information in the emissions inventory can be considered confidential business information if it meets the criteria outlined in Oregon Administrative Rule OAR 340-214-0130. Please review the Exempt from Disclosure question on the FAQ page.
