2020 Air Toxics Emissions Reporting Overview

The Oregon Department of Environmental Quality requires facilities to submit toxic air contaminant emissions inventories for the operating year from January 1 through December 31 2020 [OAR 340-245-0040(2)]. Over the course of the 2020 calendar year, facilities should closely monitor and record their operating activity and material usage in preparation for reporting to DEQ in the first quarter of 2021. Facilities in Lane County will report directly to the Lane Regional Air Protection Agency. Additional reporting information will be added to this page as it becomes available.

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

All facilities operating in Oregon with a current Air Quality permit will be required to report to DEQ their 2020 operations and activities related to toxic air contaminant emissions. This includes:

  • Air Contaminant Discharge Program permit types Basic, General*, Simple and Standard
  • Title V program

Find a reporting overview in the 2020 Air Toxics Reporting Quick Guide.

*Gasoline dispensing stations (ACDP General Permits GP-022 and GP-023) and dry cleaners (ACDP General Permit GP-006) are exempt from this reporting requirement; additional General Permit categories may be added to this exemption prior to formal Notice to Report in fall 2020. Area Source Registration permit-holders are also exempt.

​Facilities must report their toxic air contaminant emissions inventory for calendar year 2020 to DEQ by April 1st, 2021. Additional information, including online submission instructions will be available at the end of 2020.   

Anticipated timeline (schedule subject to change):
  • Fall, 2020 - Reporting forms and instructions will be available to download. The final list of exempt permit categories will be available.
  • December, 2020 - Sources will receive formal notification of reporting requirement, pursuant to OAR 340-245-0040(2)(b). 
  • April 1, 2021 - Sources will electronically submit their completed reporting form to DEQ via an online submission portal.

DEQ is requesting estimated actual emissions data for the 2020 operating year, or any operational portion of 2020. Capacity and potential emissions are not included in this request.​

ACDP General and Basic permittees will only be required to submit production and/ or material balance information. DEQ will then estimate emissions for those facilities. These facilities must provide the following information, as applicable:

  • Identification of toxics emissions units (EUs)
  • Annual production activities and fuel usages
  • Annual material usage, waste shipped offsite
  • Material information found on Safety Data Sheets
  • Identification of control devices and associated efficiencies by EU 
Category-specific reporting information for these facilities is available in the ACDP Basic and General Reporting Matrix. Additional General Permit categories may be added to this exemption prior to formal Notice to Report in fall 2020.

ACDP Simple and Standard and Title V permittees will have more specific reporting requirements. These sources will be required to provide the following information, as applicable:
  • Identification of toxics emissions units
  • 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
  • Material information found on Safety Data Sheets
  • Identification of control devices and efficiencies by EU
A printable reporting overview is available in the 2020 Toxic Air Contaminant Reporting Quick Guide.

Oregon's 600+ toxic air contaminants, including EPA's 187 hazardous air pollutants (HAPs) can be found in Table 2 of the Cleaner Air Oregon rule. This information will also be provided in the reporting form.

Operation and activities that may be omitted can be found in the list of Categorically Insignificant Activities to Exclude.

Additional information, including emission factor resources, can be found on the Air Toxics Reporting FAQ page.

A comprehensive Toxic Air Contaminant Emissions Inventory Recommended Procedures document is currently in development.

DEQ will provide standardized, Excel-based (.xlsx) reporting forms for facilities in the two reporting groups. Forms will be available for download in fall 2020 and examples will be available at that time. The use of the reporting form(s) is mandatory; alternative forms will not be accepted.

Not all facilities will have the same reporting requirements. Most General and Basic permit holders will have reduced reporting requirements and a simplified form will be provided. Refer to the ACDP Basic and General Reporting Matrix for category-specific reporting elements that may be requested.

Title V and ACDP Standard and Simple permit holders will have additional reporting requirements that include estimating their toxic air contaminant emissions. The reporting format for these facilities will resemble the AQ405CAO form, however, final details are still in development.

Facilities wishing to protect disclosure of certain aspects of their reported information may submit a public records disclosure exemption request at the time of submission. Please refer to OAR 340-214-0130 2(b) and 3(a-d) for more information.
