Question No. 419 Ms. Kirsty Duncan: With respect to the risk of corrosion and spills and other safety concerns arising from the transport of bitumen in pipelines, and to government action to address these risks: (a) how does diluted bitumen compare with West Texas Intermediate (WTI) in terms of (i) abrasive material content, (ii) acid concentration, (iii) sulphur content, (iv) viscosity; (b) to what extent is diluted bitumen more likely than WTI to cause corrosion or erosion in the pipelines through which they respectively flow; (c) what is the composition of diluted bitumen in Canada; (d) what are all of the volatile chemicals, persi ...[+++]stent organic pollutants or carcinogenic substances present in diluted bitumen in Canada; (e) in the process of diluting bitumen in Canada, what are the (i) natural gas condensates used, (ii) other petroleum products used; (f) what is the process by which diluted bitumen corrodes pipelines, with specific reference to (i) abrasion, (ii) friction, (iii) high pressure, (iv) settling of sediment, (v) velocity, (vi) sulphur-reducing bacteria, (vii) other significant factors; (g) for all proposed or existing National Energy Board (NEB)-regulated pipelines, what is (i) the amount of hard sediment passing through the pipeline annually, (ii) the average pressure, (iii) the average temperature; (h) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to determine whether diluted bitumen can flow safely through pipelines; (i) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to determine whether or not conventional crude should be distinguished from diluted bitumen when setting minimum standards for pipelines; (j) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to design safety and spill responses and spill liability management capabilities that are appropriate specifically to diluted bitumen; (k) how does a diluted bitumen sp ...

‘transmission’ means the transport of natural gas through a network, which mainly contains high-pressure pipelines, other than an upstream pipeline network and other than the part of high-pressure pipelines primarily used in the context of local distribution of natural gas, with a view to its delivery to customers, but not including supply.

Gas has to be extracted from gas fields (gas production), transported over long distances through large high-pressure pipelines (gas transmission) and (except in the case of the largest customers) transported to final customers over smaller medium- and low-pressure pipelines (gas distribution).

Gas has to be extracted from gas fields (gas production), transported over long distances through large high-pressure pipelines (gas transmission) and transported to final customers (except very large customers) over smaller medium- and low-pressure pipelines (gas distribution), as well as stored (gas storage).

Having been at the board for nearly 35 years, I remember the incident in 1985 at the farm north of Oshawa, Ontario, where a high-pressure natural gas pipeline was accidentally ruptured by the blade of a 30-tonne plow.
