Restoring the Rule of Law, Federalism, and Economic Growth by Reviewing the "Waters of the United States" Rule

Executive Order 2017-04353
Signed on March 1, 2017
45th Presidency

What it means

Directs EPA and Army Corps of Engineers to review and potentially revise the "Waters of the United States" rule that defines which waterways are federally protected. Officials must consider a narrower interpretation that aligns with Justice Scalia's opinion in a 2006 Supreme Court case.

Expected impact

  • Potential narrowing of waterways that receive federal protection, favoring a more limited definition of "navigable waters"
  • Possible reduced regulatory burden for farmers, developers, and industries that operate near waterways
  • Greater state and local control over water protection decisions
  • Environmental groups likely to oppose changes as weakening water protections
  • Economic benefits for certain industries through reduced compliance costs
