U.S. to Place Limits on Power Plant Water Pollution

WASHINGTON—For the first time in nearly 30 years, the Environmental Protection Agency plans to limit the quantity of toxic metals that coal-fired power plants release into U.S. waterways.

The agency said Tuesday that equipment required to reduce pollution in the air has increased harmful contaminants in water discharged by power plants, particularly heavy metals such as selenium, cadmium, mercury and lead. Current regulations do nothing to control metals and are not enough to protect water quality and wildlife, the agency said.

The EPA said the new rules will be unveiled in 2012.

In a preliminary study released last year, the EPA found that only a fraction of U.S. power plants were using readily available technologies to remove pollutants before they are released into waterways. The water pollution comes from scrubbers that strip gases of acid-raining causing sulfur dioxide and coal ash storage ponds where power plants store the leftovers of burning coal.

A spill at a coal ash pond in the state of Tennessee late last year, which flooded hundreds of acres (hectares) of land, damaged homes and killed fish in nearby rivers, helped raise awareness about the toxic contents of coal combustion waste and has put increasing pressure on the government to take action.

The announcement comes a day after three environmental groups threatened to sue the EPA for failing to update its regulations, first put in place in 1982. Federal law requires the agency to review regulations annually and revise them if necessary, which the advocates say the agency failed to do.

"EPA should have limited these discharges decades ago as the law requires," said Eric Schaeffer, the executive director of the Environmental Integrity Project, which along with the Sierra Club and Defenders of Wildlife, informed the EPA Monday of its plans to file a lawsuit.

Representatives of those groups said Tuesday they had not yet decided whether they would pursue the litigation.
