Dakota Access Pipeline (2016-2017)
The U.S. Army Corps of Engineers granted the Dakota Access Pipeline a series of categorical exclusions for river crossings. The Standing Rock Sioux Tribe sued, and in June 2017 a federal judge ordered the Corps to conduct a full environmental impact statement.
The pipeline was largely built before the ruling, but the court forced a fuller review of the river crossing.
The case established that categorical exclusions are vulnerable when a project's scope, location or public stakes change.
Same mechanism: a federal agency's fast-track exclusion gave way to a fuller review after public pressure. Bridgeport residents cite this precedent as they push for an even more detailed assessment.
