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, p ...[+++]ersistent 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 ...

(Return tabled) Question No. 214 Ms. Libby Davies: With regard to the impacts of oil sands development on the health of downstream surrounding First Nations and Métis communities in Fort McKay, Fort Chipewyan, Fort McMurray, Fort Resolution, Fort Fitzgerald, Fort Smith, Fort Simpson and Fort Good Hope: (a) what analysis has Health Canada conducted concerning what would have been, had there been no development of oil sand projects, the expected rates over the past decade in surrounding communities of (i) all forms of cancer, (ii) biliary tract cancer, including cholangiocarcinoma, (iii) colon cancer, (iv) lung cancer, (v) soft tissue sarcoma, (vi) leukemia, (vii) lymphomas; (b) what studies has Health Canada completed concerning the observe ...[+++]d rates over the past decade in surrounding communities of (i) all forms of cancer, (ii) biliary tract cancer, including cholangiocarcinoma, (iii) colon cancer, (iv) lung cancer, (v) soft tissue sarcoma, (vi) leukemia, (vii) lymphomas; (c) what studies has Health Canada completed concerning whether over the past decade oil sands development has been exposing, via the land, water, air or wildlife, surrounding communities to toxic substances, including (i) lead, (ii) mercury, (iii) volatile components of petroleum, (iv) polycyclic aromatic hydrocarbons, (v) dioxin-like compounds, (vi) arsenic; (d) what analysis has Health Canada conducted concerning the underlying cause, such as increased detection, chance, lifestyle risk factors or exposure to environmental contaminants, of any discrepancy between the expected and observed rates over the past decade in surrounding communities of (i) all forms of cancer, (ii) biliary tract cancer, including cholangiocarcinoma, (iii) colon cancer, (iv) lung cancer, (v) soft tissue sarcoma, (vi) leukemia, (vii) lymphomas; (e) does Health Canada plan to work with other federal departments, the Government of Alberta, and surrounding First Nations and Métis communities to complete a comprehensive stud ...

Arsenic acid and its salts with the exception of those specified elsewhere in this Annex

The tailings contain chemicals harmful to humans and aquatic organisms, including naphthenic acids, polycyclic aromatic hydrocarbons, heavy metals, and arsenic.

You already identified some a moment ago, Mr. Cooper, and I can read them to you from a list provided by Health Canada: arsenic, chloral hydrate, chlorate, chlorite, chlorine dioxide, cyanobacterial toxins, microcystins, cyanogen chloride, haloacetic acids, methyl tertiary-butyl ether, MCPA pesticide, natural protozoa, trihalomethanes, turbidity, and viruses.

Neutralize the arsenous liquor with 15 ml of sulphuric acid diluted to 10 % (w/w) and add saturated bromine water (AR quality) until the yellow colour of free bromine becomes stable (theoretically, 7 ml).
