TransCanada repeatedly claims that state of the art technology and highly trained staff will keep Energy East from leaking and that any leaks that do happen will be shut down “immediately.” They don’t like to talk about » the nine catastrophic pipeline failures on their Canadian gas lines since 1991. It is one of these Cracking, equipment or component pipelines, up to 40 years old, that TransCanada failure, and material, manufacturing or intends to convert to pump tar sands oil through. construction causes have been the most Using this old pipeline instead of building a new common reasons for pipeline2 spills of one saves TransCanada several billion dollars » more than 1,500 litres. and puts communities at even greater risk.

Energy East: When the pipeline spills... 1 What would a spill from Energy East TransCanada plans to convert a pipeline look like? system with an explosive history According to information provided at On January 25, 2014, a TransCanada-owned TransCanada’s Energy East open houses, natural gas pipeline ruptured in Otterburne, TransCanada is aiming. to be able to shut Manitoba, sending balls of flame 300 metres in down their pumping within 10 minutes of the the air. The rupture created a crater 10 feet deep, discovery of a leak Bearing in mind the total and left 4,000 natural gas customers in the cold capacity of 1.1 million barrelsmore thanof crude one permillion day, for several days. The4 cause of the rupture is still litresEnergy could East spillwould in 10transport minutes 2,024 litres of oil under investigation. In February, TransCanada per second. This means made headlines again when one of its natural . A huge amount gas pipelines ruptured5 near Rocky Mountain of oil remaining in the pipeline between valves House, Alberta. could also leak. For example, at the Nipigon River The explosion near Otterburne happened in a morecrossing than of the 10 current million natural litres gas pipeline there is 11.8 km between valve stations. This means pipeline that is part of TransCanada’s Mainline of additional oil System. This is the same system6 from which could leak after the pumping has stopped. TransCanada is seeking to convert a pipeline to NLcarry crude oil for Energy East.

In the case of the Brookdale, Manitoba Days before the now infamous Enbridge pipeline rupture, a detection system did trigger a signal, spill in Kalamazoo, Michigan of more than 3.8 but failed to register the extent of the rupture million litres of eightdiluted minutes bitumen, the pipeline’s17 hours for more than 10 minutes, by which time operator publicly stated it would remotely members19 of the public were already raising the detect a spill in . It was alarm. The other ruptures were discovered before Enbridge confirmed the massive spill by staff, nearby residents and an OPP officer. that has now cost $1 billion to clean up. It took anywhere between 10 minutes to 2.5 hours from the time of the rupture to when the In fact, the general public is far more likely to gas supply was shut off.
