The Emissions Inventory includes the amount of each toxic air contaminant emitted from each individual emissions-producing activity.
- Categorically Insignificant Activities (Form ED601): 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.
