On May 31, 2023, the Eleventh Circuit in South River Watershed Alliance, Inc. et al. v. DeKalb County, Georgia affirmed dismissal of an environmental group’s citizen suit challenging a Clean Water Act (CWA) consent decree between DeKalb County and government regulators on “diligent prosecution” grounds. The CWA precludes citizen suits if the government is “diligently prosecuting” an action to require compliance with the same standard, limitation, or order for which the citizen suit alleges a violation. The Eleventh Circuit’s opinion may provide guidance to defendants seeking to resolve government enforcement actions and obtain protection from future citizen suits.

On July 20, 2022, in Naturaland Trust v. Dakota Finance, LLC, No. 21-1517, a split Fourth Circuit panel held that a state agency’s notice of violation did not “commence an action” within the meaning of 33 U.S.C. § 1319(g)(6)(A)(ii). That provision states that a Clean Water Act violation “shall not be the subject of” a citizen suit for civil penalties if a state “has commenced and is diligently prosecuting” an action with respect to the violation “under a State law comparable to” the Clean Water Act. The court also held that this provision is not jurisdictional.

Last week, in Residents of Gordon Plaza, Inc. v. Cantrell, the Fifth Circuit denied a petition for rehearing en banc of a recent decision affirming the dismissal of a Resource Conservation and Recovery Act (RCRA) citizen suit. The key issue in the underlying appeal, 25 F.4th 288 (5th Cir. 2022), was whether certain maintenance activities qualify as a “removal” action under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The court affirmed that the maintenance activities do indeed constitute a “removal action.” Therefore, the suit was barred under 42 U.S.C. § 6972(b)(2)(B)(iv), which precludes RCRA citizen suits where a “responsible party is diligently conducting a removal action” pursuant to a CERCLA consent decree with EPA.
