"One of Trump’s first acts was to scrawl his name on an executive order that authorized coal companies to dump waste in rivers and streams. This not only promises to turn hundreds of miles of waterways into sludge, it also makes it easier for mines to practice mountaintop removal mining, simultaneously destroying a 400-million-year-old landscape and resulting in fewer jobs for miners. Not bad for one sloppy stroke of the pen. But Donald Trump is nothing if not competitive, and now he has Scott Pruitt on his side. Together, there’s nothing they can’t make worse. The Trump administration has hit the pause button on an Obama-era regulation aimed at limiting the dumping of toxic metals such as arsenic and mercury by the nation’s power plants into public waterways."
