The Trump administration is expected to announce today its final repeal of the Obama administration’s Waters of the United States rule, which cemented pollution protections for small streams and wetlands after two muddled Supreme Court decisions. The rollback is just the first step in a two-step process that aims to restrict the reach of the Clean Water Act. Today’s step overturns the Obama-era regulation, putting back in place the rules that were on the books prior to 2015. A replacement rule is expected by the end of the year. (Politico)
