Ohio county no longer has too much sulfur dioxide in the air
What happened
The US environmental regulators propose to declare the Muskingum River area in Ohio has met federal air quality standards for sulfur dioxide. This means the area will no longer be subject to special pollution reduction requirements.
Why it matters
For years, the Muskingum River area has been designated as a 'nonattainment' zone, meaning its air quality was worse than federal standards. This proposal signals that local pollution controls, likely on industrial sources, have worked. It removes a regulatory burden from the region.
The signal
Watch for the final rule from the US environmental regulators, which would confirm the redesignation and lift the special pollution controls.
