This audit protocol is intended to evaluate gas integrity management program in United States in order to ensure that operations are in compliance with the relevant transportation laws of the United States. General topics to be evaluated through this checklist include:

  • External Corrosion Direct Assessment (ECDA);
  • Internal Corrosion Direct Assessment;
  • In-Line Inspection (Smart Pigs);
  • Other Technology;
  • Integrity Assessment Via Pressure Test;
  • Repair Criteria;
  • Repair Methods and Practices;
  • Stress Corrosion Cracking;
  • Construction Welding Procedures;
  • Construction Weld Inspection;
  • Construction;
  • Pressure Testing;
  • Training and Qualification;
  • High Consequence Areas;
  • Preventive and Mitigative Measures;
  • ROW Markers, Patrols, Leakage Survey and Monitoring;
  • Coatings;
  • Specific Requirements;
  • Training of Personnel; and
  • OQ Protocol 9.

Where appropriate, a citation of the specific law or regulation, and the article of that law or regulation from which the question is derived, is provided in a separate column. This Protocol was developed from the Transportation of Natural and other Gas by Pipeline : 49CFR-192.
