Supreme Court Will Hear Challenge To EPA's 'Good Neighbor' Pollution Rule

"The U.S. Supreme Court will hear arguments Wednesday in an important environmental case that centers on the obligation to be a "good neighbor."

Lawyers representing three states, companies and industry groups will ask the justices to block a federal rule that's intended to limit ozone air pollution. Experts said it's only the third time in more than 50 years that the court has scheduled arguments on an emergency application like this one.

At the heart of the dispute is the part of the Clean Air Act known as the "good neighbor" provision. It's designed to help protect people from severe health problems they face because of pollution that floats downwind from neighboring states."
