Enbridge line 9 earthquake risks

  1. 1. Enbridge Line 9 Risks By Louisette Lanteigne 700 Star Flower Ave. Waterloo Ont. N2V 2L2butterflybluelu@rogers.com
  2. 2. Seisemic Risks & Pipeline Welds
  3. 3. Seismic Risks of Eastern Canadahttp://www.earthquakescanada.nrcan.gc.ca/zones/eastcan-eng.php
  4. 4. Earthquakes & Oil PipesPipeline damages from earthquakes can result in compression orwrinkling, joint weld cracking or separation, bending or shear fromlocalized wrinkling and tension. Joints made with oxy-acetelyne weldsbreak 100 times more than those with electric arc welded joints .

  5. 5. An earthquake occurs in the Western Quebec Seismic Zone every five days on average. http://www.earthquakescanada.nrcan.gc.ca/zones/eastcan-eng.php
  6. 6. Western Quebec Zone earthquakes include:1732, an earthquake estimated at 5.8 on the Richter scaleshook Montreal, causing significant damage.1935, the area of Temiscaming was shaken by an earthquake ofmagnitude 6.2.1944, an earthquake of magnitude 5.6, located betweenCornwall, Ontario and Massena, N.Y., caused damageevaluated at two million dollars of the time.1990, an earthquake of magnitude 5 took place near Mont-Laurier, Quebec.1996 and 1997, two earthquakes of magnitude 4.4 and 4.3occurred near Ste-Agathe-des-Monts, Quebec.
  7. 7. A REVIEW OF NBCC 2005 SEISMIC HAZARD RESULTS FOR CANADA - THE INTERFACE TO THE GROUND AND PROGNOSIS FOR URBAN RISK MITIGATION John Adams and Stephen Halchuk Geological Survey of Canada, Natural Resources Canada,
  8. 8. Problems with Polyethylene “PE” tape
  9. 9. Spingomonas and Pseudomonas Eat Plastic In May 2008, 16 year old Canadian boy named Daniel Burd from Waterloo Collegiate Institute found and isolated two naturally occurring bacterium, Spingomonas and Pseudomonas, that literally eats plastic. He stored Spingomonas and Pseudomonas at 37 degree Celsius with plastic and in six weeks time, 43% of the plastic was consumed.
  10. 10. Spingomonas and Pseudomonasnaturally occurs in Canadian soil and water. Enbridge pipelines travel across farmlands and waterways. These areas are suitable for Spingomonas and Pseudomonas because the bacterias thrives off nitrates in these locations. Warmer weather and longer growing seasons associated with climate change may serve to increase the presence of these bacterium in the natural environment.
  11. 11. Example of a PE tape issue; Kalamazoo Michigan Enbridge Oil Spill, 2010The National Transportation Safety Board (NTSB) determinesthat the probable cause of the pipeline rupture was corrosionfatigue cracks that grew and coalesced from crack andcorrosion defects under dis-bonded polyethylene tape coating,producing a substantial crude oil release that went undetectedby the control centre for over 17 hours.
  12. 12. Questions:Is there any data to either prove or disprove the roll thatSpingomonas and Pseudomonas may play in regards to“tenting” issues regarding PE tape which can result in tearsleading to corrosion issues?Is it reasonable to predict the lifespan of the oil pipes or PE tapein the absence of this data?
