This is completely wrong. Chevron is about the Clean Air Act, which required Chevron (the oil company) to get a permit for every pollution “source.” The Reagan EPA interpreted the word “source” in the statute to mean an entire plant, not an individual pollution source (like a smokestack). It was sued by the Natural Resources Defense Council, who argued that the law requires Chevron to get a permit for every pollution source.
The D.C. Circuit, in an opinion by Ruth Bader Ginsberg, sided with NRDC. But the Supreme Court reversed, ruling in favor of the EPA (and Chevron). The Supreme Court said that the court had to defer to the EPAs interpretation of the word “source,” even if the court thought that wasn’t the best interpretation of the law.
