The Environmental Protection Agency (EPA) issued a final rule determining that the St. Clair, Michigan area met the 2010 sulfur dioxide (SOâ‚‚) national ambient air quality standards by September 12, 2021. This decision is based on various data, including emissions and air quality reports. However, the area remains classified as nonattainment for these standards until specific criteria are met. This action, effective January 27, 2025, does not create new requirements or significantly impact small entities.
Simple Explanation
The EPA has decided that the air in St. Clair, Michigan now meets clean air rules for sulfur dioxide, a chemical that can make breathing hard, but they're still checking to see if everything is okay before saying so for sure. This doesn't change any rules for people or companies right now.
