(Helena, MT) — Efforts to put in a pipeline and other items in southwestern Montana are being put on hold. A federal judge okayed a preliminary injunction yesterday that will delay work in the Red Lakes Wilderness Area scheduled to begin later this month. The plans to add a pipeline, among other modifications, were aimed at helping the Arctic grayling species, but the judge believes the work would actually violate the Wilderness Act. The Gallatin Wildlife Association, Wilderness Watch and other organizations brought the challenge forward. The injunction is only temporary until a final decision is made.
