EPA's Cross-State Pollution Rule Upheld by Supreme Court

The Supreme Court has given the Environmental Protection Agency an important victory in its effort to reduce power plant pollution that contributes to unhealthy air in neighboring states.

The court's 6-2 decision Tuesday means that a rule adopted by EPA in 2011 to limit emissions from plants in more than two-dozen Midwestern and Southern states can take effect.  The pollution drifts into the air above states along the Atlantic Coast and the EPA has struggled to devise a way to control it.
