Transmission and Distribution of Gas. Stress Corrosion Cracking Direct Assessment (SCCDA) is a process to assess a covered pipe segment for the presence of SCC primarily by systematically gathering and analyzing excavation data for pipe having similar operational characteristics and residing in a similar physical environment.

## Document text

Stress Corrosion Cracking Direct Assessment (SCCDA) is a process to assess a covered pipe segment for the presence of SCC primarily by systematically gathering and analyzing excavation data for pipe having similar operational characteristics and residing in a similar physical environment.

An operator using direct assessment as an integrity assessment method to address stress corrosion cracking in a covered pipeline segment must have a plan that provides, at minimum, for:

(1) Data gathering and integration. An operator's plan must provide for a systematic process to collect and evaluate data for all covered segments to identify whether the conditions for SCC are present and to prioritize the covered segments for assessment. This process must include gathering and evaluating data related to SCC at all sites an operator excavates during the conduct of its pipeline operations where the criteria in ASME/ANSI B31.8S (as described in section 10.3 of this Title), Appendix A3.3 indicate the potential for SCC. This data includes at minimum, the data specified in ASME/ANSI B31.8S, Appendix A3.

(2) Assessment method. The plan must provide that if conditions for SCC are identified in a covered segment, an operator must assess the covered segment using an integrity assessment method specified in ASME/ANSI B31.8S, Appendix A3, and remediate the threat in accordance with ASME/ANSI B31.8S, Appendix A3, section A3.4.

  "applicabilityCaveat": "Applicability depends on the part and section, Commission jurisdiction, commodity and facility type, intrastate or interstate status, operator and activity, exemptions, waivers, federal preemption, Commission orders, and incorporated law. DPS inspects portions of interstate systems for PHMSA, but PHMSA retains federal enforcement authority. DPS states that all jurisdictional Part 256 gas-holder and Part 257 LPG-plant facilities have been decommissioned even though those regulations remain unrepealed.",
  "incorporationCaveat": "These parts incorporate or rely on federal pipeline regulations, federal and New York statutes, Commission rules and orders, and privately authored technical standards. Part 10 supplies incorporation details. References metadata preserves explicit citations but does not reproduce external material, determine licensing rights, or decide whether a particular incorporation is static or dynamic.",
  "publicationCaveat": "The New York Department of Public Service identifies these eleven Title 16 NYCRR parts as its state pipeline-safety regulations and links to the public DOS/Westlaw NYCRR reading copy. That site labels the online text unofficial and directs users needing evidentiary accuracy to the Official NYCRR maintained by the Department of State Division of Administrative Rules. Each section's 'Current through' date is the most recent official NYCRR supplement covering that section, not a uniform corpus-wide amendment date.",
  "rights": "New York government-edict text is preserved with DPS, Department of State, and publisher attribution. The public reading site's presentation and enhancements, agency marks, forms, annotations, and incorporated federal or privately authored standards require separate rights review; this connector does not claim rights in those materials.",
