One of the Supreme Court’s recurring environmental law topics is the scope of Clean Water Act (CWA) jurisdiction. Various aspects of CWA jurisdiction and implementation have been addressed over the years by the Court, including the meaning of “navigable waters” in U.S. v. Riverside Bayview Homes, Inc.

U.S. (2006), and judicial review of agency actions related to the applicability of the CWA dredge and fill permit program in Sackett v. EPA (2012) and U.S. Army Corps of Eng’rs v. Hawkes Co. (2016). Most recently, the Supreme Court heard oral argument on November 6 in County of Maui v. Hawai’i Wildlife Fund, et al., a case that addresses the applicability of the CWA’s prohibition on “point source” discharges to “navigable waters” to releases from point sources to groundwater.
