The Environmental Protection Agency (EPA) has approved changes to Colorado's State Implementation Plan (SIP) regulations, which were submitted after the EPA identified issues in the state’s handling of extra emissions during startup, shutdown, and malfunction events. These changes remove certain provisions from the SIP, making them state-only, and align with federal requirements under the Clean Air Act. While the action aims to improve air quality, it does not require an environmental justice analysis. The rule takes effect on January 27, 2025.
Simple Explanation
The EPA is saying that Colorado fixed some air pollution rules to make sure they match national rules better, and starting January 2025, everyone has to follow these new rules. They didn't check how this change affects people who don't have a lot of money or belong to minority groups, but they believe it will help make the air cleaner.
