Is the air in your county polluted?
Air quality continues to be a focus this summer as ferocious wildfires burn in the West, prompting air quality alerts across Oregon and parts of California, Nevada, Colorado, Idaho and Washington. It comes a little over a month after the U.S. Supreme Court further curtailed the federal government’s power to regulate certain air and water pollution types.In June, SCOTUS paused the U.S. Environmental Protection Agency’s “Good Neighbor” initiative, which would have restricted smokestack emissions from power plants and other industrial sources that burden downwind areas with smog-causing pollution.The 6-3 conservative majority has decreased the agency’s authority to fight all kinds of pollution, including a landmark ruling in 2022 preventing the EPA from regulating carbon dioxide emissions from power plants contributing to global warming.More significantly, the court also struck down the Chevron Doctrine, a 40-year-old ruling that required judges to defer to federal agency interpretations of ambiguous laws. Judges will now be able to interpret the laws themselves, altering the balance of power between the branches of government. This all comes as record-breaking fires scorch the western states, including mega-fires in Oregon and California. As of Tuesday, there were around 89 large active wildfires nationwide, including 31 in Oregon and 10 in California and Idaho, according to the National Interagency Fire Center. The active fires cover more than 2 million acres.The Durkee Fire in Oregon’s Blue Mountain region is the country’s largest current wildfire and the fifth largest in state history. Since lighting ignited the fire about two weeks ago, it has burned around 300,000 acres and is more than 50% contained. The state’s dozens of other large wildfires are close to collectively surpassing the massive and destructive 2020 wildfire season, which burned around 1.2 million acres and thousands of homes.California’s Park Fire has burned close to 400,000 acres but was allegedly started on purpose, according to local law enforcement. That fire is around 20% contained. While current air quality data is available for all counties in the U.S., it doesn’t appear in formal reports until the following year. The EPA’s most recently available data shows that regions affected by wildfire smoke often have the worst air quality, although temporary. It also shows places affected by more present forms of pollution, like pesticides and diesel emissions from heavy traffic. It includes pollution types regulated under the Clean Air Act: ground-level ozone, particle pollution (PM10 and PM2.5), carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2).

Landmark SCOTUS decisions and wildfires have raised air quality concerns
