The interconnected nature of the pipeline infrastructure in North America and the growing demand for energy in the US are clear drivers for cross border coordination and collaboration between PHMSA and the Canadian National Energy Board (NEB). The regulatory agencies recognize this dependency and the need for continued safe operation and expansion of the pipeline infrastructure. To achieve these goals, much is dependent on the adequacy and effectiveness of safety and specification consensus standards covering a wide range of pipeline transportation activities. In addition, pipeline regulations in the US and Canada rely largely on the partial or complete incorporation of these industry standards by reference.

In separate appendices, this study compares the major US consensus standards (ASME B31.8, American Standard Code for Pressure Piping, Section 8, Gas Transmission and Distribution Piping Systems, ASME B31.4, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, and API 1104, Welding of Pipeline and Related Facilities) with Canadian Standards Association (CSA) Standard Z662, Oil and Gas Pipeline Systems. The report is considered to be dynamic in nature and may be expected to include other comparison appendices in the future.
