EPA finalizes update to Cross-State Air Pollution Rule

Working to further prevent smog-forming pollution, the Environmental Protection Agency (EPA) recently finalized an update of the Cross-State Air Pollution Rule (CSAPR), which aims to limit air pollution that crosses state lines.
 
The update, which will improve air quality in the eastern United States, calls for 22 states to reduce their emissions of nitrogen oxide (NOx), which are a particular concern in the summer and significantly contribute to air quality issues in downwind states.
 
“Today’s update builds on the decades of success under the Clean Air Act that has led to significant cuts in nitrogen oxide emissions from upwind states that affect their downwind neighbors,” EPA Office of Air and Radiation Acting Assistant Administrator Janet McCabe said. “The common-sense actions that power plants can take to quickly and affordably reduce this harmful pollution will help protect the health and lives of millions of Americans, restore visibility at our nation’s most treasured parks, and ensure that air quality continues to improve in the eastern United States.”
 
Through the update and other changes sweeping the power sector, the EPA expects the NOx emissions will reduce by 80,000 tons, or 20 percent in 2017 from 2015 levels. The agency anticipates up to $880 million in financial benefits from the new rule.
