Air Toxics Emissions Reporting

​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 by Sept. 1, 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.


Who Should Report
​All Oregon faclities with Title V, Standard or Simple ACDP air permits 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. ​

When to Report
​​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.   

Timeline:

  • April, 2021 - Sources receive formal notification of reporting requirement
  • May, 2021 - Reporting form and Emissions Inventory Tools 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

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

What to Report

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 emission factors for toxic air contaminants by EU, associated reference information

  • Annual material usage and 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 is also 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. 

Additional information about these resources can be found on the Air Toxics Reporting FAQ page.

How to Report

​​For this request, facilities must report their emissions using the DEQ 2020 Air Toxics Emissions Inventory (ATEI) reporting form. To complete the ATEI reporting form, first assemble the items listed above in 'What to Report', then carefully read the ATEI Form Instructions tab on the reporting form. Instructions are also embedded in the form worksheets as comments. Worksheets are color-coded by emissions estimation method. Salmon orange indicates Activity and Emission Factor-derived emission estimation methods; and sage green indicates Material Balance-derived emission estimation methods. Additional information about the ATEI reporting form is available on the Air Toxics Reporting FAQ page.

DEQ has created emission factor search tools to streamline emission factor gathering for common types of equipment. Use of these tools is optional, and operators should determine if the compiled EFs best capture their facility operations, or if other equipment-specific or site-specific EFs are available. The tools are easy to use and designed to be copy/pasted directly into the 2020 ATEI reporting form. Follow the instructions on the first tab of each EF Search Tool for more information.

DEQ has created a Material Balance Quick Guide to help facilities locate SDS information and complete the ATEI reporting form with material specific information. The guide also describes how to account for control devices and material transfer or retention efficiencies.

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. Facilities wishing to prevent disclosure of certain aspects of their reported information may submit a disclosure exemption request and communicate directly with DEQ regarding submission procedures via email directly to a DEQ staff. Please review the Exempt from Disclosure question on the FAQ page for instruction.  

DEQ Sources

Submit the reporting forms using the Air Quality Document Upload Application. On July 1, 2020, facility representatives received an auto-generated PIN in an email from DEQ to upload their form to the website. Facilities will receive a proof-of-submission email confirmation when the upload is complete. A printable overview is available in the 2020 ATEI Submission Procedure Quick Guide.

LRAPA Sources

Facilities located in Lane County will use the same 2020 ATEI reporting form and DEQ tools, however these facilities should communicate directly with LRAPA staff with questions and regarding submission procedures. Visit the LRAPA ACDP Forms page for more information.
