High court’s decision seen as blow to Clean Water Act

The Supreme Court on May 25 sharply limited the federal government’s authority to police water pollution into certain wetlands, the second decision in as many years in which a conservative majority narrowed the reach of environmental regulations. The outcome could threaten efforts to control flooding on the Mississippi River and protect the Chesapeake Bay, among many projects, wrote Justice Brett Kavanaugh, breaking with the other five conservatives. Environmental advocates said the decision would strip protections from tens of millions of acres of wetlands.
