Air Toxics Reporting Background


On April 6, 2016, Governor Kate Brown launched the Cleaner Air Oregon program to protect Oregon communities through a health risk-based approach to protecting public health, and on Nov. 15, 2018 the Environmental Quality Commission adopted the Cleaner Air Oregon rules [OAR 340-245].

Under CAO, DEQ may require that Air Quality permitted and unpermitted facilities submit an updated toxic air contaminant emissions inventory once every three years, with the intention that the reporting year generally corresponds to EPA's National Emissions Inventory reporting years (2020, 2023, 2026, etc.) [OAR-340-245-0040(2).] DEQ uses these emissions inventories to:

  • Establish and maintain long term trends in air toxics emissions across geographical areas and industrial sectors.
  • Estimate Oregon's Hazardous Air Pollutants (HAPs) for the EPA's National Emissions Inventory (NEI) and the National Air Toxics Assessment (NATA).
  • Improve our understanding of air toxics emissions in communities across the state.
  • Evaluate the effectiveness of various air toxics programs and policies. 

2016 Air Toxics Emissions Inventory

The reported 2016 air toxics information has already served several functions in helping protect Oregonians and informing national understanding of toxic air contaminant sources and activities, including:

  • Use as a screening tool for the Cleaner Air Oregon Prioritization process
  • To help identify emissions of specific air toxics and areas of concern
  • To inform risk-based updates to ACDP General and Basic permit categories
  • To estimate Oregon's Hazardous Air Pollutants (HAPs) for the EPA's 2017 National Emissions Inventory and the Toxics Release Inventory

The 2016 emissions inventory for the 340 Title V and ACDP Simple and Standard facilities.
