In a regulatory move that came as no surprise, the Trump administration formally delayed implementation of the Waters of the United States rule (WOTUS), which would have increased the waters under federal jurisdiction.
The administration is still planning to propose a new rule that would permanently replace WOTUS. Timing for proposal of the new rule is unknown.
The official delay also triggered a flurry of lawsuits from state attorneys general and environmental groups challenging its legality.
The delay will give regulators at the U.S. Environmental Protection Agency an additional two years to draft and propose a new rule. This provides an opportunity to weigh in with agency officials about impacts to groundwater and concerns groundwater professionals had with the original rule proposed.
