Gov. Terry Branstad intervened in a case pending in the U.S. District Court of North Dakota Southwestern Division against the EPA and U.S. Army Corps of Engineers and their overreaching Waters of the U.S. rule. Gov. Branstad joins in support of 13 other states: North Dakota, Alaska, Arizona, Arkansas, Colorado, Idaho, Missouri, Montana, Nebraska, Nevada, South Dakota, Wyoming and New Mexico.

Nationwide, governors or attorney generals from over 31 states have taken action to ensure innovative state-based water quality initiatives, like the Nutrient Reduction Strategy, are not bogged down in Federal bureaucratic red tape.

"The WOTUS rule is a federal overreach that imposes significant barriers and impairs Iowa's ability to advance innovative, water quality practices that would actually advance our common goal of water quality," Branstad said. "I ran for Governor in 2010 to return predictability and stability to Iowa and this federal rule increases, rather than decreases uncertainty for Iowa farmers and small businesses."

In October 2014, Gov. Branstad, Lt. Gov. Reynolds, Sec. Bill Northey and various state leaders commented on the proposed WOTUS rule and stated that the Federal government's rule seems to be more concerned with Federal control over local water bodies than actually improving water quality.

"The rule is an overreach by the federal government that hurts Iowa farmers and small businesses." Reynolds said. "I applaud the work Senators Grassley and Ernst, and other member of the Iowa congressional delegation and hope this rule is withdrawn so Iowa can continue to improve water quality through the collaborative and innovative Nutrient Reduction Strategy," said Reynolds.

Iowa's Secretary of Agriculture Bill Northey said, "The misguided WOTUS rulemaking process has created uncertainty and has threatened to impede our efforts to get conservation and water quality practices on the ground. Joining this lawsuit is the right thing to do and I hope that ultimately the courts will overturn the rule."
