"Regulators are severely underestimating the health harms from the pollution that power plants dump into waterways, an environmental group said Wednesday.

In advance of an expected September rule to crack down on heavy metal pollutants from power plants, the Sierra Club released a report urging the Environmental Protection Agency (EPA) to look again at the numbers it has put out.

The group argues that with more expensive harms, the EPA’s rule could have a better cost-benefit analysis than previously estimated."
