Cross State Air Pollution Rule

National Parks Service

The U.S. Supreme Court will consider reinstating a federal regulation intended to reduce power plant pollution that contributes to unhealthy air in neighboring states.

The American Lung Association released its State of the Air 2013 report on Wednesday. Compiled with 2011 data, the report finds more than 131.8 million people in the U.S. live in counties with unhealthy levels of ozone or particle pollution.

Ozone and particle pollution grades have improved in upstate counties monitored. Seiler says that although the grades given are better than in previous years, they are not grades that any student would want to brag about, with a few exceptions.

Environmental, conservation and health groups in the region are calling for an appeal of a court decision this week that overturned the Cross-State Air Pollution Rule.
