State of South Carolina v. United States Army Corps of Engineers, No. 21-1085 (4th Cir. 2023)
Annotate this Case
In passing the Water Infrastructure Improvements for the Nation Act (“WIIN Act”), Congress directed the U.S. Army Corps of Engineers to design a fish-passage structure for the New Savannah Bluff Lock and Dam. The Corps settled on a design that would lower the pool of water by about three feet. The State of South Carolina and several of its agencies responded by suing the Corps and various federal officials. Their complaint alleged that the Corps’ design violated the WIIN Act, the National Environmental Policy Act, the Administrative Procedure Act, state law, a previous settlement agreement, and certain easements. The district court held that the Corps’ plan didn’t “maintain the pool” since it would lower it from its height on the date of the Act’s enactment. Corps argued that this reading ignores the clause “for water supply and recreational activities” and that a lowered pool that still fulfills these functions would comply with the Act.
The Fourth Circuit vacated the district court’s judgment for Plaintiffs on their WIIN Act claim and the resulting permanent injunction against the Corps. The court left it to the district court to decide whether the Corps’ chosen design can maintain the pool’s then-extant water-supply and recreational purposes. The court explained that it agreed with the Corps that pinning the required pool height to the “arbitrary and unknowable-to-Congress date that the President signed the legislation” leads to “absurd results.” Plaintiffs suggest that the statute only obligates the Corps to maintain the pool at its “normal operating range.” But neither the statute nor the district court’s order makes clear this permissible “range.”
