What kinds of information must be integrated in performing a continual evaluation of pipeline integrity?
An operator must consider all information relevant to determining risk associated with pipeline operation in HCAs. This means information regarding the likelihood that a pipeline leak or failure will occur, as well as information regarding the consequences to an HCA. At a minimum, an operator must gather and evaluate the set of data specified in appendix A to ASME/ANSI B31.8S. A list of some of the more important information that should be considered in an integrated manner is provided below. • Results of previous integrity assessments • Information related to determining the potential for, and preventing, damage due to excavation, including damage prevention activities, and development or planned development along the pipeline • Corrosion control information (e.g., Years with adequate Cathodic protection, years with questionable Cathodic protection, close interval survey results) • Information about the pipe design and construction (e.g., seam type, coating type and condition, wall th
