The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision from South Carolina's Department of Health and Environmental Control. This revision updates the state's participation in the Cross-State Air Pollution Rule (CSAPR) emissions trading programs for nitrogen oxides (NOX) and sulfur dioxide (SO2). These programs are designed to help reduce air pollution that affects other states. The EPA believes the proposed changes align with federal requirements and do not impose new obligations beyond what state law already specifies.
Simple Explanation
The EPA wants to say yes to South Carolina's plan to update how they trade pollution credits for certain gases that can travel to other states. These updates help keep the air cleaner, and the plan follows all the rules without adding new ones.
