Appendix B

Timeline of Relevant Standards and Regulations

TABLE B-1 Relevant Industry Consensus Standards and Regulations Related to the Installation of Valves onto Pipelines

Year Responsible Body or Agency Title Comment
1958 ASMEa Gas Transmission and Distribution Piping Systems–B31.8 Sections 805 and 848 establish the concepts of class location and the spacing of sectionalizing block valves.
1966 ASME Liquid Petroleum Transportation Piping Systems–B31.4 Section 434.15.2 establishes general requirements for the installation of sectionalizing block valves at major river crossings and other locations depending on terrain.
1969 U.S. DOTb Transportation of Hazardous Liquids by Pipeline–Title 49 Part 195 Incorporates the 1966 ASME standards into regulations, including the block valve installation requirements. (See above: ASME B31.4, including Section 434.15.2.)
1970 U.S. DOT Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety Standards–Title 49 Part 192 Incorporates the 1958 ASME standards into regulations, including the concepts of class location and block valve spacing. (See above: ASME B31.8, including Sections 805 and 848.)

Since 2022, automatic or remote-control shutoff valves have been required on new hazardous liquid and gas transmission pipelines located in or near populated and environmentally sensitive areas. They are intended to enable faster shutdowns of ruptured pipe segments. However, the requirement for “rupture mitigation valves” does not apply to pipelines installed prior to 2022. This report examines the regulatory requirements that apply and recommends options for making sounder decisions about when to install these valves.

TRB Special Report 349: Ensuring Timely Pipeline Shutdowns in Emergencies: When to Install Rupture Mitigation Valves from the Transportation Research Board of the National Academy of Sciences, Engineering, and Medicine is the product of an expert committee convened to assess regulatory standards and criteria for deciding when the valves should be installed on pipelines. This review, which was mandated by Congress, issues a series of recommendations designed with pipeline safety in mind.
