Protocol Item D.12

D.12 SCCDA Assessment, Examination and Threat Remediation

Verify that covered segments (for which conditions for SCC are identified) are assessed, examined, and the threat remediated. [§192.929(b)(2)]

Verify that, if conditions for SCC are present, that the operator conducts an assessment using one of the methods specified in ASME B31.8S-2004, Appendix A3.

Verify that the operator's plan specifies an acceptable inspection, examination, and evaluation plan using either the Bell Hole Examination and Evaluation Method (that complies with all requirements of ASME B31.8S-2004, Appendix A3.4 (a)) or Hydrostatic Testing (that complies with all requirements of ASME B31.8S-2004, Appendix A3.4 (b)).
1. Verify, that the operator's plan requires that for pipelines which have experienced an in-service leak or rupture attributable to SCC, that the particular segment(s) be subjected to a hydrostatic pressure test (that complies with ASME B31.8S-2004, Appendix A3.4 (b)) within 12 months of the failure, using a documented hydrostatic retest program developed specifically for the affected segment(s), as required by ASME B31.8S-2004, Appendix A3.4.

Verify that assessment results are used to determine reassessment intervals in accordance with §192.939(a)(3); (see Protocol F). [§192.939(a)(3)]
