South River Watershed Alliance, et al. v. DeKalb County, Georgia, No. 20-13651 (11th Cir. 2023)
Annotate this Case
The United States Environmental Protection Agency (“EPA”) and Georgia Department of Natural Resources (“GDNR”) sued DeKalb County for violating the Clean Water Act (“CWA”). To resolve this suit, the parties agreed to a consent decree in 2011. Eight years later, South River Watershed Alliance, Inc. (“South River”) and J.E. sued DeKalb County for failing to follow the decree and violating the CWA. The CWA authorizes citizen suits for enforcement purposes, but such suits are not allowed when an “administrator or State has commenced and is diligently prosecuting a civil or criminal action . . . to require compliance with the standard, limitation, or order.” Thus, this case turned on whether the 2011 consent decree—along with the ongoing efforts of the EPA and GDNR to require compliance—constitutes diligent prosecution. The district court determined that South River’s suit was barred by the diligent prosecution bar. On appeal, South River argued for the opposite result and requests injunctive relief to ensure DeKalb County’s compliance.
The Eleventh Circuit affirmed. The court explained that South River wants the current consent decree discarded in favor of a more muscular alternative. The fact that South River disagrees with the prosecution strategy undertaken by the EPA and GDNR, however, is not enough to prove that the EPA and GDNR have failed to diligently prosecute DeKalb County’s CWA violations. To the contrary, the record shows that the EPA and GDNR have been diligent, which means that South River’s suit is barred under 33 U.S.C. Section 1365(b)(1)(B).
