El Puente v. United States Army Corps of Engineers, No. 23-5189 (D.C. Cir. 2024)
Annotate this Case
The U.S. Army Corps of Engineers planned to dredge San Juan Harbor to facilitate the movement of large ships. The Corps published an Environmental Assessment, concluding that the project would not significantly impact the environment. The National Marine Fisheries Service also determined that the project was not likely to adversely affect certain threatened and endangered species, including seven types of coral. Three environmental groups sued the agencies, asserting that they had failed to adequately consider the project’s environmental toll. The district court granted summary judgment in favor of the defendant agencies.
The United States Court of Appeals for the District of Columbia Circuit affirmed the district court's decision. The court found that the Corps and the Service did not act arbitrarily or capriciously in carrying out their responsibilities to evaluate environmental concerns. The court rejected the plaintiffs' arguments that the Corps failed to adequately consider the breadth of the project’s impacts, erred in analyzing how the project would affect minority and low-income communities, and failed to use the best available science in assessing the project’s detrimental effect on corals. The court also found that the Corps's decision not to translate all materials into Spanish and not to extend the comment period for the Environmental Assessment when Hurricanes Irma and Maria struck Puerto Rico was not arbitrary or capricious.
