The Environmental Protection Agency is proposing to approve a set of updates to South Carolina’s air quality rules. These changes were submitted by the state in 2007, 2011, 2014, 2020, and 2025.

Why it matters: This is primarily an administrative housekeeping action. It allows South Carolina to continue managing its own air quality permits for smaller facilities without needing federal oversight for every individual project. For most people, this does not change daily life or air quality standards, but it ensures the state’s regulatory framework remains current and compliant with the Clean Air Act.

Who it affects

  • South Carolina Department of Health and Environment

The U.S. Environmental Protection Agency published this proposed rule in the Federal Register; readers should consult the official document for the specific technical details of the regulatory changes.
