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, persistent 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 ...

The investigation showed that all types of biodiesel and the biodiesel in the blends covered by this investigation, despite possible differences in terms of raw material used for the production, or variances in the production process, have the same or very similar basic physical, chemical and technical characteristics and are used for the same purposes. The possible variations in the product concerned do not alter its basic definition, its characteristics or the perception of that various parties have of it.

Given that no significant quantities of the chemical are expected to reach humans and the environment during the production and use of a closed-system site-limited intermediate, a Party, upon notification to the Secretariat, may allow the production and use of quantities of a chemical listed in this Annex as a closed-system site-limited intermediate that is chemically transformed in the manufacture of other chemicals that, taking into consideration the criteria in paragraph 1 of Annex D, do not exhibit the ...[+++]characteristics of persistent organic pollutants.

3. Member States and the Commission shall, within the assessment and authorisation schemes for existing and new chemicals and pesticides under the relevant Community legislation, take into consideration the criteria set out in paragraph 1 of Annex D to the Convention and take appropriate measures to control existing chemicals and pesticides and prevent the production, placing on the market and use of new chemicals and pesticides, which exhibit characteristics of persistent organic pollutants.
