air pollution

Eight Missouri counties received an “F” grade in The American Lung Association’s recent“State of the Air” report card. The latest report was released Wednesday – grades U.S. counties and cities on air quality. 

Out of the 17 counties with enough data available to issue a score, only Boone County received an “A” grade. And here’s the list of the counties that failed: Clay, Clinton, Jasper, Jefferson, Perry, St. Charles, St. Louis, and St. Louis city. Researchers used air quality data between 2009 and 2011 for the grading.

Government and civic leaders in southeast Missouri believe reducing ozone levels is largely out of their control because the pollutions drifts in from hundreds of miles away.

A committee of the Southeast Missouri Regional Planning and Economic Development Commission met Friday in Perryville to review data from the Environmental Protection Agency. The committee is fighting to keep the region from being designated a "nonattainment area," with pollution readings that routinely exceed EPA standards.

A federal appeals court has overturned a federal rule that would have reduced air pollution from power plants and kept it from drifting across state lines.

In a 2-to-1 decision, the panel of judges said the Environmental Protection Agency exceeded its regulatory authority when it approved the Cross-State Air Pollution rule last summer.

Sierra Club Missouri Chapter Director John Hickey says the rule would have reduced emissions of soot, sulfur dioxide, and other pollutants that drift from state to state.

A new report released today puts both Missouri and Illinois among the top 20 states with the most toxic air pollution from power plants.

The Natural Resources Defense Council report ranked Missouri 15th and Illinois 16th nationwide, based on 2010 data from the Environmental Protection Agency, the most recent data available.
