One New York power plant's air pollution controls are officially good enough
What happened
US environmental regulators approved a change to New York's air quality plan for one power plant. This means the Athens Generating Plant's nitrogen oxide emissions controls meet federal standards.
Why it matters
This is a routine administrative approval. It means one power plant in New York can continue operating its current pollution controls without further federal challenge on this specific issue. It does not change how air quality standards are set or enforced for other facilities.
The signal
Watch for any future actions that might change the definition of 'reasonably available control technology' for other power plants, as this document does not.
