The US District Court for the Middle District of Louisiana ordered the $750 million Bayou Bridge pipeline to halt construction within the Atchafalaya Basin when it concluded that the US Army Corps of Engineers’ environmental analysis likely violated the National Environmental Policy Act and the Clean Water Act due to the following deficiencies: the Corps did not provide sufficient explanation for how the proposed off-site mitigation would compensate for the loss of wetlands impacted by construction; and the Corps failed to sufficiently consider and address historical impacts to wetlands from past pipeline projects in the cumulative effects analysis. On appeal, however, the US Court of Appeals for the Fifth Circuit overturned the lower court.
