The Environmental Protection Agency (EPA) has issued a final rule that both approves and disapproves parts of Wyoming's revised Regional Haze Plan from 2022. This plan was meant to tackle air pollution affecting visibility in national parks and other protected areas. The EPA approved parts of the plan related to visibility conditions and monitoring strategies, but disapproved other parts, including long-term strategies and progress goals, because Wyoming did not adequately justify their choices and failed to include necessary emissions control measures. This rule will take effect on January 2, 2025.
Simple Explanation
The EPA looked at Wyoming's plan to clear up dirty air that makes it hard to see in beautiful places like parks. They liked some ideas but didn't like others because Wyoming didn't explain them well or include all the needed steps to clean the air.
