MISSOULA, MT. – Lolo National Forest Supervisor Carolyn Upton has signed the final Decision Notice (DN) on the Yellowstone Pipe Out-of-Service Abandonment project which is located on the Plains/Thompson Falls and Missoula Ranger Districts in Missoula and Sanders Counties.

The selected action in the final decision is a blend of alternatives 2 and 3 as evaluated in the Environmental Assessment (EA). The selected action includes the removal of approximately 2,958 feet of buried pipeline along with two over-river crossings along the Clark Fork River on National Forest System lands and includes the stabilization and abandonment of approximately 5,865 feet of the buried pipe at 4 separate locations. Annual monitoring of these sections of buried pipe would continue.

With a final decision signed, pipeline officials may begin implementation of the project immediately.
