Air Toxics Health Risk Assessment Status

DEQ notified Owens-Brockway Glass Container on March 4, 2019, that it was required to submit an air toxics emissions inventory and perform a health risk assessment as part of DEQ’s Cleaner Air Oregon program. Owens-Brockway notified DEQ on April 30, 2019 of its intent to source test, extending their source test report, emissions inventory, modeling protocol, and risk assessment work plan due date to Aug. 1, 2019. Owens-Brockway submitted its source test report on July 31, 2019 and submitted its emissions inventory, modeling protocol, and risk assessment work plan on Aug. 1, 2019. These submittals are currently under DEQ review.

Emissions Inventory

For an introduction to emissions inventories and why they matter, please see EPA’s Fact Sheet. DEQ is currently finalizing a fact sheet specific to our Cleaner Air Oregon program. A facility-specific emissions inventory timeline and associated documents are linked below.

  • Emissions inventory: An Emissions Inventory is a list of each toxic air contaminant regulated under the Cleaner Air Oregon rules that a facility emits in a given year. The Emissions Inventory includes the amount of each toxic air contaminant emitted from each individual emissions-producing activity.
  • Emissions Inventory Supporting Documentation, Including Categorically Insignificant Activities: Categorically Insignificant Activities are activities that are likely to have insignificant emissions that are not part of a facility’s primary production process. Categorically Insignificant Activities are defined in OAR 340-200-0020.
