On September 23, the U.S. Chamber of Commerce President Thomas J. Donohue warned that if the United States failed to permit the proposed Keystone XL pipeline between Alberta and Texas, Canada would simply find an alternate export route for its oil sands crude. Donohue said that Canadian crude is currently 22%, and natural gas 95%, of US petroleum imports, and foregoing the opportunity to expand on that relationship would mean deteriorated national energy security. The 700,000 barrel per day proposed pipeline has already prompted 20-year contracts between US refiners and TransCanada Corp., which a pipeline veto would jeopardize.
