May 2014 National Training Workshop on CWA §303(d) Listing & TMDLs

Purpose of the Training Workshop

To provide an opportunity for state, tribal, and territorial participants from Clean Water Act Section 303(d) programs—along with their federal counterparts—to learn about and discuss ways of implementing the Prioritization Goal of the new Long-Term Vision for Assessment, Restoration, and Protection under the Clean Water Act Section 303(d) Program.

 

Clean Water Act Jurisdiction

The U.S. Supreme Court issued the latest in a series of rulings defining the scope of the federal Clean Water Act in 2023, in Sackett v. United States. Prior rulings also affected the reach of the Act, including SWANCC v. U.S. Army Corps of Engineers (2001) and Rapanos v. United States (2006), created great uncertainty for landowners, environmental advocates, and regulators about whether many types of wetlands, small and intermittent streams, and other waters are subject to federal jurisdiction.

The Environmental Law Institute works throughout the Chesapeake Bay region to promote new tools that support smart growth and reinvestment across the Bay states. Although the Institute has focused extensively on Pennsylvania and Maryland, we have also engaged in Chesapeake Bay-wide research on smart growth.
