The U.S. Environmental Protection Agency (EPA) has rejected an effort to loosen water quality protection rules in Iowa, saying proposed changes to "antidegradation standards" sought by the Iowa Department of Natural Resources (IDNR) violate federal rules.

In a letter to the IDNR January 19, the EPA's Region 7 Administrator Mark Hague wrote the state was "seeking to establish a one-size-fits-all rule that only projects costs less than 115 percent of base costs optimize 'the balance between water quality benefits and project costs.' "
