Report of the Committee on Criteria for Installing Automatic and Remote-Controlled Shutoff Valves on Existing Gas and Hazardous Liquid Transmission Pipelines of which I was chair.

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.
