Rule Section: §192.917(e)(3)

Manufacturing and construction defects.

Rule Hierarchy:

• 192.917  How does an operator identify potential threats to pipeline integrity and use the threat identification in its integrity program?
  • 192.917(e)  Actions to address particular threats.
    • 192.917(e)(3) Manufacturing and construction defects.

Rule Language:

If an operator identifies the threat of manufacturing and construction defects (including seam defects) in the covered segment, an operator must analyze the covered segment to determine the risk of failure from these defects. The analysis must consider the results of prior assessments on the covered segment. An operator may consider manufacturing and construction related defects to be stable defects if the operating pressure on the covered segment has not increased over the maximum operating pressure experienced during the five years preceding identification of the high consequence area. If any of the following changes occur in the covered segment, an operator must prioritize the covered segment as a high risk segment for the baseline assessment or a subsequent reassessment.
(i) Operating pressure increases above the maximum operating pressure experienced during the preceding five years;
(ii) MAOP increases; or
(iii) The stresses leading to cyclic fatigue increase.
