The Emissions Inventory provides information on all the Toxic Air Contaminant emissions from a facility, and includes information on a facility’s operations and activities, as well as fuel and material usage rates. This is often the longest step in the CAO risk assessment process as DEQ needs to verify that all activities have been accounted for, and that the most representative emissions data available are used. In some cases, DEQ will require a facility to perform source testing at this stage if insufficient data is available to estimate emissions.
For an introduction to emissions inventories and why they matter, please see EPA's Fact Sheet. 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.
