This proposal is the second step in a comprehensive, two-step process intended to review and revise the definition of ‘‘waters of the United States’’ consistent with the Executive Order signed on February 28, 2017, ‘‘Restoring the Rule of Law, Federalism, and Economic Growth by Reviewing the ‘Waters of the United States’ Rule.’’ This proposed rule is intended to increase CWA program predictability and consistency by increasing clarity as to the scope of ‘‘waters of the United States’’ federally regulated under the Act.
