More air pollution is coming from the smokestacks of coal-fired plants in Pennsylvania than in almost any other state in the nation, says a new report from the Natural Resources Defense Council. 
 
The non-profit environmental group puts Pennsylvania in third place on its Toxic 10 list.  The report says plants here emitted more than 31 million pounds of chemicals in 2010, accounting for 78 percent of all the air pollution in the state.  N-R-D-C clean air director, John Walke, says the good news is, Pennsylvania's emissions were down 24 percent from 2009.  He says that's better than a nationwide 19 percent decrease during the same time, attributed to two major factors.
 

 
The report says Pennsylvania's Keystone Generating Station and the Homer City Station are among the top ten power plant polluters in the country. The numbers used in the report come from the EPA's Toxic Release Inventory, which is a national database of toxic emissions provided by industrial sources.
