§ 120.1 - Purpose and scope.
This part contains the definition of “waters of the United States” for purposes of the Clean Water Act, 33 U.S.C. 1251 et seq. and its implementing regulations. EPA regulations implementing the Clean Water Act use the term “navigable waters,” which is defined at section 502(7) of the Clean Water Act as “the waters of the United States, including the territorial seas,” or the term “waters of the United States.” In light of the statutory definition, the definition in this section establishes the scope of the terms “waters of the United States” and “navigable waters” in EPA's regulations.
