EPA proposes stricter limits on coal plant water pollution
The Biden administration on Wednesday proposed tighter limits on wastewater pollution from coal-burning power plants that has contaminated streams, lakes and underground aquifers across the nation. Under the Clean Water Act, the Environmental Protection Agency sets pollution standards to limit wastewater discharge from the power industry and other businesses. The Trump administration rolled back pollution standards so utilities could use cheaper technologies and take longer to comply with guidelines for cleaning coal ash and toxic heavy metals such as mercury, arsenic and selenium from plant wastewater before dumping it into waterways. The Biden administration’s proposal for stricter standards at coal-burning plants also encourages the plants to retire or switch to other fuels such as natural gas by 2028.
