On 12 December, the US Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) issued an advisory bulletin to owners and operators of gas 呦乐园 to provide guidance on how to identify and periodically confirm high consequence pipeline areas.
The advisory also recommends operators add a buffer zone to an area of potential impact to help ensure proper high consequence area identification.
The identification guidelines rely on pipeline-specific information relating to the location, size, and operating characteristics of a line, as well as the identification of structures, specified sites and their intended usage along the pipeline route.
