U.S. Chamber files amicus brief supporting certiorari

December 09, 2015

In its brief, the U.S. Chamber urged the Supreme Court to review a Third Circuit decision affirming EPA’s “total maximum daily load” (“TMDL”) regulation for the Chesapeake Bay. Unlike previous TMDLs established by states, which fix a daily cap on the specific water body, this TMDL establishes pollutant limits for point and nonpoint sources across the 64,000 square mile Bay watershed, sets deadlines for states to implement control measures for those sources, and demands “reasonable assurances” from states that the deadlines will be met, backed by federal sanctions.

The brief, filed jointly with the National Association of Manufacturers and National Federation of Independent Business, argues that the TMDL will adversely affect National Pollutant Discharge Elimination System (“NPDES”) permits and facility operations, and that the TMDL’s offset requirements further paralyze economic growth.

Catherine E. Stetson and James T. Banks of Hogan Lovells served as co-counsel for the amici with the U.S. Chamber.
