Arkansas Shown Face of Tar Sands Oil Spills

From: Dave Lincoln, our Brown Field's Expert

This horror story is about the 80,000 gallon plus oil spill in Mayflower AR from the Exxon/Mobil Pegasus pipeline break. This spill only hints at the pollution potential from an inevitable breach of the proposed KXL pipeline which would carry Canadian Tar Sands oil to the Gulf Coast.
  1. For the most part, news camera crews have been kept out of the area so most of the images have come from residents.
  2. Note that none of the cleanup crews or volunteers have masks. Years from now they may be told that breathing the PAHs  have made them chronically ill. The mixture often includes benzene, a known human carcinogen.
  3. Bitumen extracted from tar sands has the consistency of peanut butter and must be diluted to flow through pipelines. The diluted bitumen (dilbit) from the Canadian Tar Sands is extremely corrosive and toxic.  A National Energy Board study assumed a standard dilbit containing 33% condensate (resulting in product with "21.5 °API and sulphur content of 3.3 percent") but the actual formulation varies by heavy oil characteristics and availability of dilutants.
  4. Residents near the spill who have not been evacuated have been told nothing about the long tern health risks to their families from breathing the polluted air.
  5. Residents are completely unaware that it may never be completely safe for them to return to their homes. They should immediately demand permanent relocation before people realize the true value of their contaminated homes and foundations.
  6. The proposed Keystone XL pipeline might be capable of transporting 1. 3 million gallons per hour. This is more than 50 times worse than the Pegasus pipeline in Arkansas.
