On May 7, President Donald Trump issued Executive Order No. 13921, Promoting American Seafood Competitiveness and Economic Growth, stating that it is U.S. policy to “facilitate aquaculture projects through regulatory transparency and long-term strategic planning.” To further this policy, the Order directs the U.S. Army Corps of Engineers to create a nationwide permit for aquaculture operations, and tasks the National Oceanic and Atmospheric Administration with a variety of planning- and permit-related responsibilities.

In County of Maui v. Hawaii Wildlife Fund, the U.S. Supreme Court held, 6-3, that the Clean Water Act requires a national pollutant discharge elimination system permit “when there is the functional equivalent of a direct discharge.” The Court also decided Atlantic Richfield Co. v. Christian, holding, 7-2, that landowners adjacent to a Superfund site were potentially responsible parties under the Comprehensive Environmental Response, Compensation, and Liability Act.
