North Carolina changes how it measures sulfur pollution from power plants

North Carolina has changed its rules for measuring sulfur dioxide emissions from power plants and other burning sources. The state will now use a different method to check if these sources are meeting air quality limits.

For years, environmental regulators have used specific methods to measure pollution. Changing these methods can make it easier or harder for companies to meet emission limits, even if the actual amount of pollution doesn't change. This shift means North Carolina's environmental agency will now assess compliance differently, which could affect how much sulfur dioxide is actually released into the air.
