Canada’s Pipe Dream Threatens the Salish Sea

Canada continues to push forward on its Trans Mountain Pipeline expansion despit overwhelming opposition and damning evidence — as well as serious economic headwinds — against it.

Coauthored with Janet Alderton, whose brief bio appears below.

Despite overwhelming opposition from British Columbia, Washington state, and tribes, counties and cities on both sides of the border, plus strong evidence that the Trans Mountain Pipeline Expansion Project will inevitably harm the endangered Southern Resident Killer Whale population, the Canadian National Energy Board has recommended that the project should proceed. This is a deeply flawed decision.

Of paramount concern to Washington citizens are the adverse impacts on the struggling orcas, whose population in the wild is now down to 75 members — close to the lowest level in decades. If this project is completed as planned, an additional 590,000 barrels of Canadian crude oil could be shipped daily from the Westridge Terminal in Burnaby, BC; that would result in a seven-fold increase in tanker traffic to more than 800 transits per year through the orcas’ critical habitat in Haro Strait, the Strait of Juan de Fuca, and adjacent Salish Sea waters.

The additional underwater noise from hundreds more tankers annually will be difficult if not impossible to mitigate. This inevitably greater racket will further obscure their favorite Chinook salmon prey, which the orcas track and find using echolocation. And the tugboats necessarily accompanying these huge, lumbering tankers for safety reasons would ironically generate even more underwater noise.

Spill off Tsawwassen would coat Whatcom County waters and beaches.
A major spill off Roberts Point would coat Whatcom County waters and shores, according to a computer simulation.

If a major oil spill were to occur in the Salish Sea from one of these tankers, the impact on the orcas would be devastating, likely wiping out the entire species. The purported “clean up” of conventional floating oils is a widespread industry myth, as their recovery level is 20 percent at best. After the volatile components evaporate, the remaining heavier oils can remain in the marine environment for decades — as shown by the residues that still linger in Alaska’s Prince William Sound 30 years after the Exxon Valdez spill.

But not only could such a large spill in Haro Strait coat nearby shores and tidelands with sticky, smelly ooze. If the tanker carried diluted bitumen from tar-sands deposits in Alberta, a sizable portion of it could also separate and sink to the sea floor under conditions of high winds and waves — smothering benthic species there, including the Pacific sand lance that are a principal prey of Chinook salmon.

So why does the Canadian government want to push forward with this ill-considered project in the face of overwhelming opposition and damning evidence? It’s because the Trans Mountain pipeline is the only option it has left to get added Alberta tar-sands crude oil to tidewaters, where it could be shipped overseas and supposedly earn higher profits. After two other such pipelines had been cancelled, the federal government bought the existing Trans Mountain pipeline [2] for CA$4.5 billion (US$3.7 billion) to keep the third option alive. And it will cost Canada at least another CA$7.4 billion to nearly triple its capacity.

But the likely government decision to expand this pipeline is based on deeply flawed economic analysis. The demand for high-sulfur tar-sands crude is projected to drop when the International Maritime Organization’s global pollution standards become more stringent less than a year from now. All large commercial vessels must significantly reduce their sulfur-dioxide emissions by January 1. Most will do that by switching to low-sulfur fuels rather than the high-sulfur bunker fuels that have been commonly used on ocean-going vessels. And because Alberta tar-sands crudes have among the highest sulfur contents in the world, which makes refining them costly, the market for them is likely to plummet.

Moreover, Canada’s fervent hope that Asian markets for its heavy crudes will materialize is a pipe dream. According to a recent Greenpeace analysis, 92 percent of the current shipments from Burnaby go to US refineries, mostly in California and Washington, able to handle heavy, sulfur-laden crudes. That number is unlikely to change much should the expansion go through.

The Aframax-size tankers that can load crude oil in Burnaby and pass under Vancouver’s Lions Gate Bridge are too small to compete in international markets with the gigantic supertankers now plying the oceans. And Asian refineries have been reluctant to invest the billions required for the additional infrastructure needed to refine high-sulfur crude oil economically when lower-sulfur crudes are available.

The 92 percent of shipments to US refineries do not include the more than 150,000 barrels of Canadian crude oil that currently enter our state daily via the Puget Sound Pipeline System, a spur of the Trans Mountain Pipeline that supplies Whatcom and Skagit County refineries. These refineries will have to face the same diminishing markets for high-sulfur fuels — and resolve what can be done with all the sulfurous byproducts that will soon begin piling up.

In all likelihood, the added Trans Mountain pipeline capacity would be for nought. And Canadian citizens will be left holding the bag, wondering how they ever got snookered into wasting billions on such an economic dinosaur.

Janet Alderton is president of the Friends of the San Juans, a nonprofit organization working to protect the San Juan Islands for people and nature, including oil spill prevention throughout the Salish Sea. She is serving her second term on Washington state’s Citizen’s Committee for Pipeline Safety, a group convened by Governor Chris Gregoire after two boys were killed in the 1999 Bellingham pipeline explosion.

Here we have another, well-written diatribe regarding the dearth of Orca in the local waters and the threats (real or imagined) to their continued residency.

I read the article and no mention was made of the continued, century-old dumping of human waste (i.e. black water and sludge) into those same waters.

Why can we not focus on the real, clear and present dangers presented to the wildlife now and then think about the other proposed dangers?

Nice article but I believe it to be misplaced effort.

According to a recent, authoritative NOAA report, noise pollution from passing vessels is one of the three major factors adversely impacting the orcas and limiting their population growth — the other two being, yes, toxic pollutants in Salish Sea waters and the dearth of the orcas’ favorite prey, Chinook salmon. We’ve examined the first in some detail and feel qualified to write about it, as well as on marine transport of tar-sands crude oils and on the politics and economics of exporting them. Other writers could address the valid issue of toxic pollutants.

Whatcom County residents should also be aware of the large amounts of sulfur that are entering the county via Puget Sound Pipeline system. These amounts will grow dramatically if the Trans Mountain expansion project goes forward, including upgrades to the Puget Sound Pipeline — which is now owned by the Canadian federal government.
