EPA: Power plants main global warming culprits

WASHINGTON — The most detailed data yet on emissions of heat-trapping gases show that U.S. power plants are responsible for the bulk of the pollution blamed for global warming.

Power plants released 72 percent of the greenhouse gases reported to the Environmental Protection Agency for 2010, according to information released Wednesday that was the first catalog of global warming pollution by facility. The data include more than 6,700 of the largest industrial sources of greenhouse gases, or about 80 percent of total U.S. emissions.

According to an Associated Press analysis of the data, 20 mostly coal-fired power plants in 15 states account for the top-releasing facilities.

Gina McCarthy, the top air official at the EPA, said the database marked "a major milestone" in the agency's work to address climate change. She said it would help industry, states and the federal government identify ways to reduce greenhouse gases.

The Obama administration plans to regulate emissions of heat-trapping gases under existing law.

The largest greenhouse gas polluter in the nation in 2010, according to the EPA's data, was the Scherer power plant in Juliette, Ga., owned by Southern Company. That coal-fired power plant reported releasing nearly 23 million metric tons of carbon dioxide, the chief greenhouse gas, in 2010.

Two other power plants owned by Southern were the second- and third-largest polluters nationally: the Bowen plant in Cartersville, Ga., and the James H. Miller Jr. power plant in Quinton, Ala.

American Electric Power, another large coal-fired power producer, has three power plants in the top 20. They are in Rockport, Ind., Cheshire, Ohio, and St. Albans, W. Va.

The other states with high-polluting power plants are Texas, Michigan, Missouri, Montana, Pennsylvania, Arizona, Wyoming, North Carolina, Kansas and Kentucky.

Refineries were the second-largest source of greenhouse gas emissions, with 5.7 percent of the reported total. The top states in greenhouse gas emissions from power plants and from refineries were Texas, Pennsylvania, Florida, Ohio, and Indiana.
