The EPA is confirming that the St. Louis area, which spans Missouri and Illinois, has met federal air quality standards for ozone pollution. This means the region no longer needs to follow strict pollution-reduction requirements that were previously in place. This matters to residents and businesses in the St. Louis area because it reduces regulatory burdens, though it also means there may be less active monitoring to ensure air quality stays clean going forward.
