The Trump administration will on Thursday repeal one of the Obama era's most sweeping environmental rules — a set of pollution protections for small streams and wetlands that had riled up opposition from coal miners, home developers, farmers and oil and gas drillers.
The action creates instant doubts about the legal status of myriad seasonal or isolated wetlands and thousands of miles of waterways, including vast swaths of the arid West. And it clears the way for the Environmental Protection Agency to finish a follow-up regulation in the coming months that could leave most of the nation's wetlands without any federal safeguards.
EPA Administrator Andrew Wheeler is poised to sign off on the repeal at the D.C. headquarters of the National Association of Manufacturers, one of the industry groups that had opposed the Obama administration's Waters of the U.S. rule.
