REPORTING · 29th November 2011
Below are statements in response to the report issued Nov. 29, 2011 by the environmental activist organizations: Natural Resources Defense Council, the Pembina Institute, and Living Oceans Society. All statements below are attributable to Paul Stanway, spokesman for Enbridge Northern Gateway.
• A Nov. 28 2011 statement from Alberta Innovates, stated that the group recently completed “an independent and fact-based analysis” to address concerns surrounding pipelines carrying diluted bitumen. Corrosion specialist Dr. Jenny Been performed an indepth review of “corrosivisity” of dilbit in pipelines in comparison to conventional or non-oilsands crude oil.
• Alberta Innovates stated: “Based on chemical and physical characteristics of dilbit, Dr. Been concludes that the characteristics of dilbit are not unique and are comparable to conventional crude oils during pipeline flow. Analysis of historic data shows that the internal corrosion related pipeline failure rate of dilbit is statistically comparable to the conventional oil in the US.”
• Enbridge has been transporting crude from oil sands production since 1979 – our Athabasca System (which went into service in April 1999) was the first liquids pipeline directly linking both the Athabasca and Cold Lake Oil Sands deposits with the pipeline transportation hub at Hardisty. A complete metal loss inspection of this line in 2009 revealed no increased risk or incidence of internal corrosion.
• We currently transport more than 80 unique commodity types that range in sulphur content, viscosity, etc.
• Crude oil viscosity, sulphur content, and total acid number have not been associated with increased risk or incidence of internal corrosion on the Enbridge system.
• The Alberta regulator, the Energy Resources & Conservation Board (ERCB), has many years of experience in regulating pipeline transportation of products from the Alberta oil sands and with regulating all pipelines associated with oil and gas production in Alberta.
• The ERCB, based on their comprehensive statistics on pipeline performance since 1975, states: “there is no indication that the types of pipelines transporting blended crude bitumen, crude oil or synthetic crude oil have an increased risk of internal corrosion issues. Further, it is our expectation that the Alberta frequency of crude oil pipeline failure would not be worse than the failure frequency exhibited by hazardous liquids pipelines in the USA if data was adjusted to equalize reporting requirements and the selection of the sample group.”
• There are no established links between our 6B failure to internal corrosion to crude oil settling in fresh water. Neither the NTSB nor PHMSA have suggested internal corrosion was cause of Marshall. The Marshall leak remains under investigation by both agencies – no findings have been released to date.
• Both Canada and the United States have comprehensive regulations that require pipeline operators to assure products transported adhere to quality specifications and the pipeline is designed, inspected and maintained to prevent internal corrosion.
well now im a believer

great findings, but youre still having spills, poop painted green is still poop, say what you want, im sorry doesnt fix a thing, no pipeline- no spill, my kindergarten teacher called it.....basic math
