BISMARCK, N.D. (AP) — A federal judge in North Dakota is giving attorneys until Tuesday night to file briefs arguing the scope of his injunction blocking a new Obama administration water rule.

U.S. District Judge Ralph Erickson last week issued a temporary injunction requested by North Dakota and 12 other states to stop the U.S. Environmental Protection Agency and the Army Corps of Engineers from regulating some small waterways under the Clean Water Act.

The EPA says the injunction applied only to the 13 states that filed the lawsuit. Attorneys for the 13 states say the judge’s ruling has “nationwide scope.”

The states say the regulation is an overreach by the federal government. The federal agencies say the rule clarifies the law and actually makes it easier for the states to manage some waterways.
