PHMSA Releases a Final Rule Expanding the Required Use of Excess Flow Valves
October 14, 2016
On October 14, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published its Final Rule entitled “Expanding the Use of Excess Flow Valves in Gas Distribution Systems to Applications Other Than Single-Family Residences” (EFV Final Rule) in the Federal Register. The agency had previously issued a pre-publication version of this rule on October 7. See Babst Calland’s Pipeline Safety Alert. In response to statutory changes and a National Transportation Safety Board recommendation, PHMSA is expanding the existing requirement that operators install an excess flow valve (EFV) on certain natural gas distribution pipelines to include additional types of new or replaced service lines. The agency is also requiring curb valves or other manual shut-off valves on new or replaced service lines with meter capacities above 1,000 standard cubic feet per hour and requiring operators to notify customers of their right to request the installation of an EFV on certain types of service lines. The EFV Final Rule will become effective on April 14, 2017.
