Does PHMSA Pipeline Safety expect operators to apply different relative risk ranking systems for lines in HCAs?
An operator must have a process that considers all factors that affect the likelihood and consequences of pipeline failure and produces a relative risk ranking of pipeline segments that can affect HCAs. This same process can also be applied to other pipeline segments outside of HCAs. However, when conducting integrity management inspections, PHMSA Pipeline Safety expects to review a relative risk ranking of all segments that can affect HCAs as part of the Baseline Assessment Plan review.
