A federal judge has dismissed a challenge from the Oregon Cattlemen’s Association to the Trump Administration’s Navigable Waters Protection Rule, leaving the rule in effect in that state.

A federal judge has declined to block implementation of the Trump administration's Navigable Waters Protection Rule, which will allow it to go into effect Monday as scheduled, replacing the Obama-era "waters of the U.S." rule.

Seventeen states and two cities are suing the Trump administration over its Navigable Waters Protection Rule, joining a host of environmental groups that have already filed lawsuits challenging the new definition of "waters of the U.S."

The lawsuits have begun over the government’s latest attempt to define “waters of the U.S.,” with New Mexico ranchers and Chesapeake Bay conservationists challenging the recently published rule.

The Trump administration has released a replacement for the former “waters of the U.S.” rule that significantly reduces federal jurisdiction over streams and wetlands, triggering what almost certainly will be a series of protracted legal battles over the scope of the Clean Water Act.
