Last month a Montana federal judge shook up the infrastructure industry when he vacated a widely used U.S. Army Corps of Engineers permit. This month the judge amended his order to rein in its reach. Now Nationwide Permit 12, or NWP 12, can be used for installation of non-pipeline projects such as cable, electric, and internet. But the judge left in place an injunction against using the permit for building oil and gas pipelines. SDPB's Victoria Wicks has this report.
