The Clean Water Act in the Supreme Court: Recent Developments By Timothy S. Bishop*, Mayer, Brown, Rowe & Maw LLP The Supreme Court has in recent Terms waded into two jurisdictional issues under Clean Water Act Sections 402 and 404: the scope of the federal government’s “geographic” jurisdiction over water and, with regard to jurisdiction over “activities,” the meaning of the key statutory term “addition.” 1.

simply because migratory birds land on them and those birds have some connection to interstate commerce through hunting and bird watching. In so holding, the Court, 5-4, adopted the view that the constitutional grounding of the CWA is Congress’s Commerce Clause power over commercial navigation, not the alternative “instrumentalities of commerce” or “substantial connection with commerce” strands of the commerce power. Properly understood, SWANCC means that because CWA jurisdiction rests on Congress’s power over navigation, isolated, intra-state, non-navigable waters may not be regulated by the federal government at all under the statute. In that regard, the Court’s decision in SWANCC is consistent with its renewed insistence, since Lopez and Morrison, that the Commerce Clause has teeth and that the limits of that power are to be rigorously policed by the courts using close analysis of the relevant commerce connection.2 Since SWANCC many state and local governments have moved to fill the jurisdictional gap over isolated waters, exercising power that Congress intended in the CWA to reserve to the state and local governments best placed to understand the needs of local environments and economies.3 Not content, however, with the federalist allocation
