The Environmental Protection Agency (EPA) has made an administrative update to how materials are organized in the Wisconsin State Implementation Plan (SIP) for air quality. This update involves a new format for incorporating materials by reference, ensuring that all state air quality regulations are correctly organized and can be easily accessed and enforced. This change is considered administrative, meaning it doesn't introduce new laws but makes existing laws easier to understand and apply. The revised format is effective from April 22, 2025, and is designed to help both the EPA and the public identify relevant air quality regulations in Wisconsin.
Simple Explanation
The EPA has made it easier for people and themselves to find and understand the rules about clean air in Wisconsin by changing how the information is organized, a bit like rearranging a messy toy box so everything is easier to find and use. This change doesn't create any new rules, it just makes the old ones clearer and starts from April 22, 2025.
