2020 Air Toxics Emissions Reporting Overview

The Oregon Department of Environmental Quality requires permitted facilities to submit toxic air contaminant emissions inventories for the calendar 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 third quarter of 2021. Facilities in Lane County will report directly to the Lane Regional Air Protection Agency. Refer to 'Who Should Report', below, for updated information. Additional reporting details will be added 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 ACDP, 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. 

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

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

DEQ will provide a standardized, Excel-based (.xlsx) reporting form for facilities. The form will be available for download in spring 2021, and examples will also be available at that time. The reporting format 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.
