Iowa League of Cities v. EPA

 

us-coa-8thThe League sought direct appellate review of two letters sent by the EPA to Senator Charles Grassley, arguing that these letters effectively set forth new regulatory requirements with respect to water treatment processes at municipally owned sewer systems. The League argued that the EPA lacked statutory authority to impose these regulations and violated the Administrative Procedures Act (APA), 5 U.S.C. 500 et seq., by implementing them without first proceeding through the notice and comment procedures for agency rulemaking. The court concluded that the case was ripe for judicial review and the League had standing to assert its claims; the court vacated both the mixing zone rule in the June 2011 letter and the blending rule in the September 2011 letter as procedurally invalid; and the court vacated the blending rule as an excess of statutory authority insofar as it would impose the effluent limitations of the secondary treatment regulations internally, rather than at the point of discharge into navigable waters. The court remanded to the EPA for further consideration.
