The Environmental Protection Agency (EPA) is set to establish more stringent standards on water pollution from coal-fired power plants. The EPA on July 26 announced it would reinstate Obama-era regulations that were rolled back by the Trump administration.
An EPA official on Monday said the new rule would impact about 100 coal-fired plants. The agency said it would begin the rule-making process to reduce pollution, including toxic metals such as mercury, arsenic and selenium, though changes could take a few years to go into effect—meaning the current standards, which include dozens of environmental regulations that were weakened by the Trump EPA—will remain in place.
