HCA Definition – Latest Proposal

The DOT has proposed revisions to the Gas Pipeline High Consequence Area (HCA) definition, to take into consideration the directional flow of gas along a pipeline route in the event of a major pipeline rupture (think Carlsbad, NM). The HCA definition has evolved significantly since the “official” HCA definition was published on August 6, 2002. The DOT’s latest thoughts are in a document which can be downloaded from RCP’s website here through the Pipeline Integrity Management Gateway. Industry is anxiously awaiting the final version of the HCA definition so that HCA surveys can begin, which are fundamental to gas pipeline integrity management program development.
