The Environmental Protection Agency (EPA) has issued a final rule establishing deadlines for states to submit revisions to their air quality plans when a region is reclassified as having worse ozone pollution. This rule specifies the requirements for new deadlines when areas are reclassified under the Clean Air Act, aiming to ensure consistent and timely submission of needed plans to improve air quality. The rule also simplifies the process by removing some past obligations that no longer apply once an area has been reclassified. These changes help to ensure that areas meet national air quality standards effectively.
Simple Explanation
The EPA made new rules so that states have to work faster to clean the air when it's too polluted. They also made things a bit easier by taking away old rules that aren't needed anymore.
