Emissions Inventory

The ORCAA Annual Emission Inventory is a collaborative effort between ORCAA and the industrial or commercial businesses (sources) in its jurisdiction. ORCAA’s jurisdiction includes Clallam, Jefferson, Grays Harbor, Mason, Pacific, and Thurston counties in the state of Washington. ORCAA collects emissions-related data from the larger sources on an annual basis.

The reports above give the actual amounts of pollutants emitted from these large sources during the calendar year. The report does not include emissions from mobile sources (transportation), outdoor burning, small point sources, or small area sources (e.g. dry cleaners, gas stations, autobody shops). Pollutants are emitted through emission stacks or as fugitive emissions where no stack exists. Emissions of criteria pollutants are listed in tons per year. Emissions of toxic air pollutants are listed in pounds per year. Each report within a document is sorted by city and business name.

All Emissions Inventory documents are formatted as PDF's .
