The Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) is seeking comments on a request it plans to make to the Office of Management and Budget to gather information on excess flow values (EFVs). The agency said it wants to collect data on operators’ experiences, practices, benefits and costs associated with the use of ETVs. An EFV is a device designed to limit the impact of a potential leak or explosion by restricting the flow of natural gas if a line is broken or damaged. The information to be collected is necessary to conduct a cost-bnefit analysis of requiring an expansion of the use of EFVs, the PHMSA said. Comments should be submitted by July 16 to or by mail to the Docket Management Facility; DOT, 1200 New Jersey Ave. SE., West Building, Room W12-140, Washington, DC 20590-0001.
