The US Supreme Court blocked for the foreseeable future a Biden administration rule that would mean stringent new emissions requirements on power plants and pipelines in parts of the country to stem ozone pollution that wanders into downwind states.

The justices, voting 5-4, put the Environmental Protection Agency’s “good neighbor” rule on hold while courts consider challenges pressed by upwind states, industry groups and companies led by Kinder Morgan Inc. A dissenting opinion said the majority ignored EPA’s authority in protecting air quality standards.
