Here's a statement from the Nez Perce Tribe, whose reservation includes 70 miles of the route that proposed mega-loads of oil equipment would travel along Highway 12 in north-central Idaho, in response to news that ISP patrols to accompany ExxonMobil's proposed mega-loads were approved by the state back in 2009. The tribe opposes the loads:

“The Nez Perce Tribe has significant treaty-reserved and cultural resource and safety concerns with Highway 12 being turned into an industrial corridor.  These concerns have been formally communicated to the United States Forest Service and Federal Highway Administration leadership and we are awaiting their response.  The Nez Perce Tribe was not contacted about the nature and impact of these projects until recently.  At that point, it was becoming quite apparent that the contact was not in the nature of a consultation about proposed projects but rather an informational session about what would be occurring.”
