The Nez Perce Tribe in Idaho is challenging an oil company's plans to transport oversized loads through Montana. Exxon Mobil wants to move the massive equipment along Highway 12 into Canada.

But the route could be cutting across part of the historic Nez Perce Trail. The tribe wants to be consulted.

Imperial/Exxon Oil contracted with Missoula Electric Cooperative to bury overhead powerlines on the route. M-E-C asked Lolo National Forest for its approval.

Lolo Forest signed the decision. But it has now rescinded it to consult with the Nez Perce. Co-op general manager Mark Hayden says crews will move ahead with other work.

Hayden says, " most of our modifications have been completed that we have permits for along Highway 12." He says now we will shift our attention to Highway 200 to complete those crossings for which we have permits."

Exxon Mobil wants to start transporting the equipment by fall. Weather is always a factor in Montana.

Department of Transportation chief operations officer Dwane Kailey says, it has the potential to effect the start date or the potential for Imperial Oil to move their loads.

The D-O-T has not issued final permits for the wide loads. It is currently reviewing comments from the public.
