Missouri removes old sulfur dioxide rules, keeps current pollution limits

Missouri updated its state air quality plan by replacing an old sulfur dioxide rule with a newer version. This change removes outdated requirements but does not make pollution limits stricter for power plants.

This document is a bureaucratic cleanup. It ensures that Missouri's air quality rules are consistent and up-to-date without changing how much sulfur dioxide power plants can emit. It means the state's environmental regulators are maintaining the status quo, not tightening or loosening pollution controls.
