CPM represents a group of non-profits in litigation against the Environmental Protection Agency over the Trump Administration’s determination that the Cargill Salt Ponds located in Redwood City were not “waters of the United States” under the Clean Water Act, and therefore not entitled to any federal protection or restriction. The suit was filed under the Administrative Procedures Act, alleging the government’s determination was arbitrary, capricious, and contrary to law. The case is currently pending in the Northern District of California.
