The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by South Carolina to update its Cross-State Air Pollution Rule (CSAPR) emissions trading programs. This revision incorporates recent changes made by the EPA to federal regulations concerning the trading programs for nitrogen oxides and sulfur dioxide emissions from large electric generating units. The approval ensures that South Carolina's program remains consistent with federal requirements and the Clean Air Act's provisions. The rule will take effect on April 7, 2025, and will not impose additional requirements beyond those established by state law.
Simple Explanation
The EPA is saying "yes" to a plan from South Carolina that helps big power plants that make electricity control some of the smoke and gases they release so that less pollution goes into the air. This plan makes sure the state is following the same pollution rules as everyone else, just like when everyone follows the same rules in a game.
