TC (the client) proposes a two phase approach to research and analyze the supply chains for petroleum products in Canada with respect to safety, and to identify additional DGs by-products and associated products, and transportation activity.Phase1–Provide DGs related information on oil extraction activities up to the point where the DGs reach a refinery or pipeline, including crude oil. Phase 2 - Provide information on transportation, processing and distribution activities from the refinery to the point where the products are sold to major geographic market. The objective of the proposed study is a complete analysis of the supply chains relative to safety of the crude oil and petroleum products, by-products and waste products in Canada. This supply chain encompasses the extraction and upgrading of crude oil products, the transport to and subsequent refining at refineries until the aforementioned products reach the primary distribution center. A general emphasis is being placed on petroleum fuels and liquid petroleum gasses (LPG), (hereafter referred to as petroleum products), however non-fuel petroleum products will also be captured so long as they are still DGs in accordance with Schedule 1 of the Transport of Dangerous Goods Regulations (hereafter referred to as the “Regulations” or “TDG Regulations”).Motivation:Transport Canada (TC), based on risks, develops safety standards and regulations, provides oversight and gives expert advice (through the Canadian Transport Emergency Centre — CANUTEC) on DGs accidents to promote public safety in the transportation of DGs by all modes of transport in Canada. The Transport Dangerous Goods (TDG) Directorate is the focal point for the national program to promote public safety during the transportation of DGs. The TDG Directorate serves as the major source of regulatory development, information and guidance on DGs transport for the public, industry and government employees.TC expects that the related data, analysis, and conclusions of this study will support the TDG Directorate’s mandate, provide insight into emerging trends in the refining sector, and by extension, a deeper understanding of how oil and petroleum products move from various activity centers across Canada. This knowledge is required by the TDG Directorate in order to continue fulfilling its delegated activities under SO 3 of the aligned program architecture.
