This Comment examines the legal framework for state protection of nonfederal waters and its implications for cooperative federalism. After a brief overview and legal background, it identifies some recent state actions that attempt to fill gaps in coverage created by changes in federal interpretations of the Clean Water Act. It then summarizes the current scope of state regulation of waters in every state, in order to discern the likely impact of changes at the federal level on the status of waters in the states.

Salmon require cool temperatures to migrate and reproduce. The Clean Water Act (CWA) requires states to develop and implement water quality standards sufficient to produce fishable waters. Nearly a half-century after its 1972 enactment, the modern federal statute’s goal of fishable waters has yet to be achieved in the case of salmon streams.

Nearly nine million tons of plastic waste flow into our oceans each year, arriving in many ways—ranging from polluted rivers and waterways to the wastewater from our washing machines. Once in the ocean, this pervasive plastic pollution is nearly impossible to clean up. If there is anything positive to say about such a broad and complex challenge, it is that there are multiple ways to tackle the problem. Legal and policy solutions are increasingly moving away from the piecemeal, product-by-product approach of single-use plastic bans and toward mor

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.

Section 401 certification and permit conditioning under the Clean Water Act is one of the most significant tools for states to influence federally permitted activities involving discharges into navigable waters. However, states are required to set conditions within one year or they forgo their ability to do so. In practice, the one-year review is difficult for states to meet and led to a common practice known as “withdraw and resubmit” in which states could reset the clock. But in Hoopa Valley Tribe v. Federal Energy Regulatory Comm’n, the D.C.
