Particulate Matter (PM) Air Quality Standards
Based on the Environmental Protection Agency's (EPA's) reconsideration of the air quality criteria and the national ambient air quality standards (NAAQS) for particulate matter (PM), the EPA is revising the primary annual PM2.5 standard by lowering the level from 12.0 µg/m3 to 9.0 µg/m3. The Agency is retaining the current primary 24-hour PM2.5 standard and the primary 24-hour PM10 standard. The Agency also is not changing the secondary 24-hour PM2.5 standard, secondary annual PM2.5 standard, and secondary 24-hour PM10.

84 percent of PM2.5 is from so-called “non-point” sources, meaning the contaminants are more challenging to control. Smoke from wildfires and common dust (including that arising from roads, construction, and agricultural activity) comprise 43% and 16% of all PM2.5 emissions, respectively. Only 16% of PM
emissions come from “point” sources, such as power plants and industrial sources.9 Further, the ambient levels of PM in many counties are affected by emissions originating outside the county itself since.
Emissions from non-point sources like wildfires are particularly susceptible to being transported extremely
long distances by the prevailing winds. Even PM originating in other countries, such as China, can help
drive a county into nonattainment status.10
* Due to winds, counties in highly forested states, like California, can be significantly impacted by
wildfire PM, such as smoke, from upwind counties.11 However, while a particular county may not be
responsible for such smoke, it would still suffer the economic consequences were it to be deemed to be in nonattainment as a result.
* In the summer of 2023, Canada suffered from 900 wildfires. For weeks, the smoke from these fires was transported to the United States, affecting at least 32 states.12 This foreign contribution of PM could well affect a given county’s attainment status.
With burdensome regulatory disincentives, counties, and states lose out on manufacturing, construction, and other job-creating opportunities. If the unreasonable PM2.5 standards proposed by
the Biden administration are ultimately finalized, it seems inevitable that more companies will look to offshore their projects.
