EPA proposes changes to Cross-State Air Pollution Rule

The Environmental Protection Agency (EPA) recently proposed revisions to its Cross-State Air Pollution Rule (CSAPR) as it impacts the 2008 ozone air quality standards.

The aim is to lessen the impact of oxides of nitrogen (NOx) emissions on downwind states in the Eastern U.S.

The rule, which is outlined in the Clean Air Act’s “good neighbor” provision, requires states to address air pollution that is carried across their borders into other states where it affects their ability to achieve air quality standards.

The EPA’s proposed updates would reduce NOx emissions from 23 eastern states that cause problems for downwind states. Under the good neighbor provision, the EPA can create a federal implementation plan (FIP), which the proposed revisions include, for states that do not create adequate plans of their own.

“This update will help protect the health and lives of millions of Americans by reducing exposure to ozone pollution, which is linked to serious public health effects including reduced lung function, asthma, emergency room visits and hospital admissions, and early death from respiratory and cardiovascular causes,” EPA Administrator Gina McCarthy said. “The proposed updates support states’ obligation to address air pollution that is carried across state lines.”
