Federal regulations require natural gas transmission pipeline operators identify high consequence areas for integrity management. Once identified, the pipeline must be periodically assessed and mediated if faults are found. Assessments cost money and the main question an operator has is “Do I really need to assess this section of pipe?” The answer lies in the validity of the HCA. This paper will discuss several methods to discover and validate high consequence areas and associated identified sites.
