This map shows the air emissions reported by major industrial, commercial, and institutional facilities that have an Air Operating Permit (AOP). Each major facility is represented by an icon that, when clicked, shows the annual tons of pollutants (Carbon Monoxide, Volatile Organic Compounds, Nitrogen Oxides, Ammonia, Coarse Particles, Fine Particles, and Sulfur Dioxide) and greenhouse gases (Carbon Dioxide, Methane, Nitrous Oxide, and Fluorocarbons) emitted into the air. All air pollutant values are from the 2016 Comprehensive Emissions Inventory. All greenhouse gas (GHG) values are from the 2016 GHG Reporting Data. Note that GHG data uses metric tons while AOP data uses US short tons.

The Air Operating Permit (AOP) Regulation Program requires a permit for a facility if it has the potential to annually emit more than 100 US tons per year of any regulated air pollutant. The GHG Reporting Program requires reports from facilities that emit more than 10,000 metric tons (11,023 US tons) per year of CO2-equivalent GHGs. Note that not all AOP sources are required to report GHGs. See the About Tab for links to more information.

Certain large facilities and transportation fuel suppliers are required to report their greenhouse gas (GHG) emissions to Ecology beginning with the 2012 emissions year. Owners or operators of the following are required to report:
• Facilities that emit at least 10,000 metric tons of carbon dioxide equivalent (CO2e) of greenhouse gases per year in Washington.
• Suppliers of liquid motor vehicle fuel, special fuel, or aircraft fuel that supply products equivalent to at least 10,000 metric tons of carbon dioxide per year in Washington.

Sources are grouped by sectors. Most sectors focus on each facility’s onsite emissions. The transportation fuel supplier sector describes emissions associated with the complete combustion or oxidation of fuels supplied by transportation fuel suppliers under the Washington Department of Licensing Fuel Tax Program.

This dataset does not include all of Washington’s emissions. See the Washington State Greenhouse Gas Emissions Inventory (https://ecology.wa.gov/Research-Data/Scientific-reports/Statewide-greenhouse-gas-inventory) for statewide emissions totals.

Emissions are in units of metric tons of carbon dioxide equivalents using AR4 global warming potentials as specified in WAC 173-441.

WDFW Juvenile Salmon Density Data

Routine freshwater monitoring data collected by the The WA State Department of Ecology's River and Stream Monitoring Program are summarized by a technique called the "Water Quality Index" (WQI). The WQI ranges from 1 (poor quality) to 100 (good quality). The WQI summary does not include non-standard elements like metals. For temperature, pH, oxygen, and fecal coliform bacteria, the WQI is based on criteria in Washington’s Water Quality Standards, WAC 173-201A.
For nutrient and sediment measures where standards are not specific, results are based on expected conditions in a given region. Multiple constituents are combined and results aggregated over time to produce a single score for each station and each year.
