A measure has been signed by the president to rescind a major Obama administration water regulation and direct an end to the government's defense of the rule. The Waters of the United States rule expanded the number of waterways that are federally protected under the Clean Water Act. The rule has faced intense opposition from farmers, energy companies and Republicans in Congress, including Michigan congressman John Moolenaar.

“By withdrawing this and then promising to work towards a rule based on sound science and common sense, this really assures farmers and landowners that we're going to have a new process where permits will [be] required and best practices will be followed,” he says.

Withdrawal of the act will likely face court challenges from some state attorneys general and environmental groups.
