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.)

Year Responsible Body or Agency Title Comment
2000 U.S. DOT Pipeline Integrity Management in High Consequence Areas (Hazardous Liquid Operators with more than 500 Miles of Pipeline) Final Rule 49 CFRc 195.452 requires an operator to take measures to prevent and mitigate the consequences of a pipeline failure that could affect a high consequence area.
2003 U.S. DOT Pipeline Integrity Management in High Consequence Areas (Gas Transmission Pipelines) Final Rule 49 CFR 192.935 requires operators to take additional measures beyond those required by Part 192 to prevent and mitigate the consequences of a pipeline failure in a high consequence area.
2022 U.S. DOT Pipeline and Hazardous Materials Safety Administration’s rupture mitigation valve rules for newly constructed and entirely replaced segments of pipelines See Chapter 3 for a more detailed discussion of the rule.
