How often must periodic integrity assessments be performed on pipeline segments that can affect an HCA after the baseline assessment is completed?
Assessments must be performed at intervals determined by the operator based on segment-specific risk factors. Scheduled intervals must be no longer than 5 years (195.452 (j)(3)) unless an operator has sound technical justification for a longer interval and notifies PHMSA Pipeline Safety of its intent to use the longer interval. Whatever interval is selected must be technically defendable.
