4. Earthquakes & Oil Pipes
Pipeline damages from earthquakes can result in compression or
wrinkling, joint weld cracking or separation, bending or shear from
localized wrinkling and tension. Joints made with oxy-acetelyne welds
break 100 times more than those with electric arc welded joints .

5. An earthquake occurs in the Western Quebec Seismic Zone
every five days on average.

6. Western Quebec Zone earthquakes include:
1732, an earthquake estimated at 5.8 on the Richter scale
shook Montreal, causing significant damage.
1935, the area of Temiscaming was shaken by an earthquake of
magnitude 6.2.
1944, an earthquake of magnitude 5.6, located between
Cornwall, Ontario and Massena, N.Y., caused damage
evaluated 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 4.3
occurred near Ste-Agathe-des-Monts, Quebec.

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. Spingomonas and Pseudomonas
naturally 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. Example of a PE tape issue;
Kalamazoo Michigan Enbridge Oil Spill, 2010
The National Transportation Safety Board (NTSB) determines
that the probable cause of the pipeline rupture was corrosion
fatigue cracks that grew and coalesced from crack and
corrosion defects under dis-bonded polyethylene tape coating,
producing a substantial crude oil release that went undetected
by the control centre for over 17 hours.
12. Questions:
Is there any data to either prove or disprove the roll that
Spingomonas and Pseudomonas may play in regards to
“tenting” issues regarding PE tape which can result in tears
leading to corrosion issues?
Is it reasonable to predict the lifespan of the oil pipes or PE tape
in the absence of this data?
