Lay of the Land
There are no surprises in the President’s proposal to vastly narrow the definition of wetlands and other waters protected by the federal Clean Water Act. Within a month of taking office in 2017, the President issued an executive order directing EPA and the Corps of Engineers to begin that process.
Nor are there any surprises in the new definition itself. As expected, EPA and the Corps of Engineers propose to replace the Obama-era definition – which was based upon the Supreme Court’s Rapanos decision – with a much narrower definition proposed by late Justice Antonin Scalia.
Under the new rule, the Clean Water Act’s protections will extend only to truly navigable rivers and their tributaries, as well as wetlands abutting those rivers or having a direct hydrologic connection. The Clean Water Act will no longer protect millions of acres of wetlands found in different habitat types around the Country, including most of the vernal pools and other seasonal wetlands found throughout California’s rangelands and foothills.
