In a lawsuit that could have a broader impact than just halting the pipeline, the Sierra Club has brought a lawsuit against the US Army Corps of Engineers’ issuance of a NWP 12 permit to the Keystone Gulf Coast Project. The NWP 12 permit authorizes construction, maintenance and repair of linear utility lines in waters of the US along the entire permitted route of the pipeline. The lawsuit is challenging the project permit and is a facial challenge to the Corps’ authority to issue the NWP 12, which, if successful, would cancel the Corps’ ability to issue the NWP 12 and force operators to apply for individual permits for each impacted water of the US. The case is Sierra Club, Inc. v. Bostick, 5:12-cv-00742, filed in the West District Court for Oklahoma. Click here for the Complaint.
