Re: Review Board IR #2.07 – Barging Data for Great Slave Lake

On September 21st, 2012 the Review Board sent an information request to Transport Canada requesting data on barging-related events on Great Slave Lake. In its response, Transport Canada indicated that it did not collect such data. Transport Canada directed the Board to the two agencies that do collect this type of information: the Canadian Coast Guard (pleasure craft), and the Transportation Safety Board of Canada (commercial vessels).

Subsequently, Board staff contacted those agencies likely involved in the oversight of marine activities on Great Slave Lake, including:

Canadian Coast Guard; Transportation Safety Board of Canada; and Environment and Natural Resources, GNWT.

The Canadian Coast Guard (CCG) manages the Marine Pollution Incident Reporting system (online since 2000). The data provided by the CCG to the Review Board includes incidents occurring on Great Slave Lake from 2000 until present (Appendix A).

The Transportation Safety Board of Canada (TSB) is an independent agency that advances transportation safety by investigation of occurrences of marine transportation and other modes of transportation. The TSB provided the Review Board with information of reportable incidents from 1975 until present for Great Slave Lake (Appendix B).

Environment and Natural Resources is a division of the Government of the Northwest Territories that administers the Hazardous Materials Spills Data Base which is a repository of reportable spills within the NWT. ENR supplied the Review Board with a list of all marine spills in the NWT from 1971 until present (Appendix C, D).

Terms of Reference Section 3.5 Accidents and malfunctions 2. Describe and predict the potential impacts to the local water quality of Great Slave Lake from concentrate spillage at both barge loading/unloading sites, both in the short term and over the life of the mine. 4. Describe consequences of accidents, malfunctions, or “impacts of the environment on the development” that may affect water quality and quantity and the ability of the water management system to function. For both sites the following scenarios, at a minimum, will be considered: h. potential impacts to water from tailings spills or leaks; i. potential impact to any valued components from any spill of any product. 6. Conduct a best-practice risk assessment for the project, exploring the potential for events listed in points 1 through 5. Discuss systems, components, hazards and associated failure modes. The developer will assess likelihood and severity of each risk identified from the points 1-5. 7. Describe the impacts of any other potential accidents or malfunctions not listed here.

Preamble Several potential barge accident or malfunction scenarios other than sinkings could have negative impacts on water quality or other valued components. To assess the likelihood of such scenarios, a review of the past record of barge incidents is warranted.

Request Please provide statistical information on past barge incidents in Great Slave Lake or other representative areas, including but not necessarily limited to cargo spills, fuel spills, collisions, groundings, and hull leaks.

Transport Canada’s Response: Transport Canada does not collect statistical information or maintain a database on the number of incidents in marine waters. The Canadian Coast Guard and the Transportation Safety Board amass data on past incidences related to marine shipping.

The Canadian Coast Guard’s Regional Marine Information Centers manage and collect information regarding past environmental incidents in arctic marine waters. The Regional Marine Information Centers are the collector and disseminator of marine pollutant spills reports, or land/air based spills that affect the coast.

Detailed statistical information on past fuel spill incidents in arctic marine waters can be provided by the Canadian Coast Guard. Please contact the following for more information:
