The Trump administration is proposing easing more Obama-era protections on contaminants from coal-fired power plants. Environmental Protection Agency administrator Andrew Wheeler signed a proposal Monday overhauling a 2015 rule on release of contaminated wastewater from power plants. The EPA says the change will save $175 million annually in compliance costs.
