Good Neighbor Provision

New Hampshire politicians from both sides of the aisle are praising a decision from the US Supreme Court upholding the right of EPA to regulate air pollution that crosses state borders.

The so-called “good neighbor” provision could mean Appalachian and Rust-Belt states will have to clean up their coal plants. The Northeast has already scrubbed the emissions from its power plants, but still endures low air-quality days in part because of emissions blowing in on the Jetstream from western states.
