The Environmental Protection Agency (EPA) has proposed a new rule regarding California's Regional Haze State Implementation Plan (SIP) for the second implementation period. The EPA plans to partially approve and partially disapprove the SIP submitted by California. While the plan addresses some standards, such as monitoring and emission inventories, it falls short in areas like setting proper long-term strategies and progress goals related to visibility improvement. This proposed rule opens a discussion about the elements of the SIP that meet federal requirements and those that need further improvement.
Simple Explanation
The EPA is looking at California's plan to make the air clearer and cleaner, and they think some parts are good but others need more work to make sure we can see far and clear in special places. They're asking people to talk about what works and what doesn't in the plan.
