There is no overwhelming science on this one.
Here read for yourself, it’s been basically blocked since inception in about half of the states.

The U.S. Environmental Protection Agency and U.S. Army Corps of Engineers finalized a rule in June 2015 that significantly expanded the definition of “waters of the United States,” also known as “navigable waters,” under the Clean Water Act. EPA failed to listen to concerned farmers, ranchers and business owners around the country in crafting its new rule, vastly expanding EPA’s and the Corps’ regulatory authority beyond the limits approved by Congress and affirmed by the U.S. Supreme Court. The rule was challenged in court by dozens of state, municipal, industry and environmental organizations. It was quickly blocked by the 6th Circuit Court of Appeals based on its legal flaws and the harm it threatened to cause, and was never implemented nationwide.
The 6th Circuit never decided the merits of the 2015 rule, and in early 2018, the U.S. Supreme Court determined that review of the 2015 rule belonged with federal district courts, not with the courts of appeals. Although AFBF agreed with the Supreme Court’s decision, this meant that the 6th Circuit’s nationwide stay would be lifted as its stay was no longer in effect. Meanwhile, the agencies finalized an “Applicability Date Rule” delaying implementation of the 2015 rule until 2020 while the agencies continue to work to repeal and replace the illegal 2015 rule.
The U.S. District Court for the District of South Carolina struck down the Trump administration’s rule delaying implementation of the Obama WOTUS rule nationwide. While the court expressly applied its ruling nationwide, district courts in North Dakota and Georgia had previously blocked the Obama rule in 24 states. Later, the North Dakota court added Iowa to its list of states where the Obama rule is blocked, and a district court in Texas added the states of Texas, Louisiana and Mississippi.
The number of states where the WOTUS rule has been temporarily blocked by the courts has risen to 28, leaving the 2015 WOTUS rule in place in 22 states.[1] AFBF is deeply involved in the ongoing legal battles and is using all available means to block implementation of the illegal 2015 rule.
[1] The states where the 2015 WOTUS rule is currently in place are California, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, Tennessee, Vermont, Virginia and Washington. Four of these (OH, OK, MI and TN) have requested court injunctions but have not yet been granted relief.
Impact
The 2015 rule grants the federal government regulatory control over virtually any waters – and many land areas that only temporarily hold water – assuming a scope of authority Congress never authorized. It effectively eliminates any constraints the term “navigable” previously imposed on the agencies’ Clean Water Act jurisdiction, and few, if any, waters would fall outside of federal control.
The 2015 rule provides none of the clarity and certainty it promised. Instead, it creates confusion and risk by giving the agencies almost unlimited authority to regulate, at their discretion, any low spot where rainwater collects, including common farm ditches, ephemeral drainages, agricultural ponds and isolated wetlands found in and near farms and ranches across the nation, no matter how small or seemingly unconnected they may be to true “navigable waters.”
The 2015 rule defines terms such as “tributary” and “adjacent” in ways that make it impossible for farmers and ranchers to know whether the specific ditches, ephemeral drains or low areas on their land will be deemed “waters of the U.S.” But these definitions are broad enough to give regulators (and citizen plaintiffs) justification to assert that such areas are subject to Clean Water Act regulation and give the agencies sweeping new authority to regulate land use, which they may exercise at will, or at the whim of a citizen plaintiff.
AFBF Policy
Farm Bureau has significant concerns with the 2015 rule. It expands federal jurisdiction far beyond what was authorized by Congress, resulting in the imposition of burdensome requirements, widespread uncertainty and legal risk for farmers and ranchers.
AFBF strongly supports the agencies’ proposal to repeal the 2015 rule. AFBF also urges the agencies separately to develop a new rule that will provide a clear and reasonable definition of “waters of the U.S.” within the limits set by Congress.
