At this writing, the first huge steel module to leave the port of Lewiston by truck en route — on a test run — to the Alberta tar sands is stuck at Lolo Pass, immobilized by a Montana court restraining order. The module, which with the trucks hauling it weighs roughly half a million pounds, left Lewiston on April 11 in the dead of night. Its journey may pave the way for 206 other modules that Canada's largest oil company, Imperial Oil, which is 70 percent owned by Exxon Mobil, wants to ship up the Columbia, through Idaho and into Montana on two-lane Highway 12, and then on to Alberta.
Or it may not.
Missoula County, the National Wildlife Federation, the Montana Environmental Information Center, and the Montana Chapter of the Sierra Club have gotten the Montana restraining order. They argue that the Montana Transportation Department, which has given permission for the modules to travel through the state, should have to file a state environmental impact statement before it modifies Highway 12 for the megaloads and turns it into an industrial corridor.
On the Idaho side of the border, Idaho Rivers United (IRU) has filed a suit in federal court. This suit alleges that by not acting to prevent the module shipments along the Wild and Scenic River corridor through which the state of Idaho has an easement for Highway 12, the Forest Service has violated the Wild and Scenic Rivers Act and other laws.
Given all these obstacles, Imperial/ExxonMobil, which had the modules fabricated in Korea, has started cutting the ones already barged to Lewiston in half, so that they can fit under bridges and be trucked along freeways to Canada, bypassing Highway 12. Meanwhile, the company is reportedly looking at other ways to get future modules from Korea to Alberta, possibly through the Panama Canal and then all the way around to the port of Churchill, on Hudson's Bay.
All this is a classic story of outsized, western-style engineering. Here are the basics of the saga, which has a lot of potential impact on the Puget Sound region, as we shall see. The Alberta tar sands (or oil sands or whatever you call them) represent the largest known reserve of petroleum outside Saudi Arabia. Canada sendsto the United States more oil than any other foreign country. The Alberta tar sands yield half of Canada's oil production.
Tar sands are mixtures of viscous, petroleum-bearing bitumen with clay and gravel. The mixture is stripmined from the ground, then dumped into big cells where hot water or steam separates the bitumen from the other constituents. The water slurry is then agitated, and bitumen is skimmed from the surface. After the substance is purified further, it can be refined into oil. The 207 modules that need to find a way to Alberta will be the cells in which bitumen is separated from sand and clay.
Opponents object to the stripmining, which is eating into Alberta's boreal forest, and to the massive infusions of water and energy needed to extract the sands and turn the goo into something you can use in your car. The process puts a lot of carbon dioxide into the air. Burning the finished product puts in a lot more. (The National Wildlife Federation, one of the plaintiffs in the Montana suit, is waging a related campaign against tar sands oil.)
Last I noticed, Americans haven't stopped driving, and dirty or not, the tar sands represent a whole lot of petroleum right at our door. Work has started on a controversial Keystone XL pipeline network that would run from Alberta, through the Midwest, to refineries on the Texas Gulf. That would bring even more petroleum extracted from Alberta sands to U.S. gas pumps.
Earlier this year, The Washington Post editorialized that "[o]il sands crude is nasty, and the sooner the world stops burning it, the better. But," the paper continued, "that's actually not much of a reason to kill the pipeline." The New York Times disagreed, arguing that moving ahead with the pipeline "would be a huge error."
If the trade in tar sands oil goes global, it will have implications for Puget Sound. The Post also noted that "Chinese firms are already buying stakes in Canadian oil sands production, and projects are planned or under way to increase exports from Alberta to Asia." And how would those exports get to Asia? Craig Welch reported recently in The Seattle Times that one company's plans for shipping tar sands oil to Asia "would quadruple tanker traffic through Vancouver, B.C., and dramatically increase the amount of oil traveling through the Strait of Juan de Fuca."
Opposition in Idaho and Montana tends to focus on what may happen along Highway 12. The highway follows the Middle Fork Clearwater and Lochsa rivers along a Wild and Scenic River corridor through the Clearwater National Forest almost all the way to the border. People who visit the area to hike, fish, hunt, and just look at the trees spend millions of dollars there. Opponents argue not only that the shipments will transform this scenic area into an industrial corridor but also that by transforming it, the shipments would undercut one of the area's few economic advantages. The shipments of the massive machinery would certainly tie up traffic, inconveniencing locals and periodically preventing emergency vehicles from getting through. In the first stages of the test run, the module now stuck at Lolo Pass clipped an electrical wire, cutting off power to hundreds of people.
The IRU suit alleges that the Imperial/ExxonMobil shipments through Idaho would be just the first of many; four other companies have expressed an interest in the same route. It says that the Forest Service has erred by saying it has no jurisdiction over the loads because it has already granted an easement to the Idaho Transportation Department (ITD). The terms of the easement, the Wild and Scenic Rivers Act, and the National Forest Management Act not not only permit but require it to act, the plaintiffs say. Besides, they argue, the module megaloads exceed the terms of the easement. "An easement is usually for a normal and customary use," says IRU conservation director Kevin Lewis. The shipment of megaloads represents "an absolute change" in use.
The Idaho Transportation Department has issued permits for the megaloads to move, but opponents objected, and the ITD held an administrative hearing. At the hearing, the ITD argued that the loads couldn't be cut down. Imperial/ExxonMobil had made the same argument.
