Review of Integrity Assessment Results Protocols Office of

Review of Integrity Assessment Results Protocols Office of Pipeline Safety Integrity Management Workshop July 23 -24, 2002

Required Program Elements § 452 (f) An operator must include, at minimum, each of the following elements in its written integrity management program: • (3) An analysis that integrates all available information about the integrity of the entire pipeline and the consequences of failure • (4) Criteria for remedial actions to address integrity issues raised by the assessment methods and information analysis Office of Pipeline Safety • (8) A process for the review of integrity assessment results and information analysis (by a person qualified to review the results and information)

Objectives • Verify adequacy of operator’s process, and its implementation, to review integrity assessment results • Verify the integration of assessment results with other information related to pipeline integrity Office of Pipeline Safety • Verify coordination and consistency of excavation & remediation plans with assessment conclusions

Clarity & Completeness of Process Documentation • Consistency of Implementation Procedures • Assessment & Review Process Records • Qualification of Reviewers • Assurance of Program Quality Office of Pipeline Safety • Intra/Inter-Organizational Communications • Active Search for Process Refinements & Improvements

Clarity & Completeness of Requirements on Assessment Process • Assessor Experience and Capabilities • Assessment Tools & Accuracy • Reporting Requirements & Report Timing • Notification of Potential Threats to Integrity Office of Pipeline Safety • Format & Content of Report • Operator Management of Exceptions to Requirements

Operator Review & Validation of ILI Results • Results Evaluation Due within 180 Days • Notification of Operator if Above not Possible • Requirement to Reduce Pressure if Immediate Repair Condition Present • Number of Calibration/Validation Digs • Verification of Accuracy & Position • Excavation Dig Data Requirements Office of Pipeline Safety • Verification of Location/Dimensions of Feature • Analysis of Defect Severity

Operator Review & Validation of Pressure-Test Results • Practices Used in Pressure. Testing • Documentation of Metallurgical Examinations of Failures • Actions Taken if Pressure Reversals Experienced Office of Pipeline Safety

Integration of Assessment Results with Other Integrity. Related Information • Include Results from Previous Assessments • Include Results from Other Monitoring Programs • Include Historic Failure, Maintenance, and Repair Information • Risk-Factor Data (Condition of Pipeline & Environment) • Identify Major Integrity Issues, Locations & Implications Office of Pipeline Safety • Evaluate Trends in Pipe Condition • Action Required if Immediate Repair Condition

Categorize Defects & Prepare Excavation Plan • Categorization of Anomalies Consistent with Rule Requirements • Repair or Temporary Reduction in Pressure for “Potential Threats to Pipeline Integrity” • Development, Implementation & Tracking of Excavation Plan Office of Pipeline Safety • Incorporation of Results from Data Integration in Excavation Plan

Program Quality & Potential Improvements • Look for Clear & Consistent Implementing Procedures • Periodic Review of Procedures • Requirement for Verification Checks Office of Pipeline Safety • Organization Polling to Ensure Value-Added Information is Identified, Received and Incorporated

Documentation of Results Review & Dissemination of Information • Development of Records from Review Process • Distribution of Review Results • Include Feedback to Assessor • Orchestrated to Promote the Continuous Improvement of Processes Office of Pipeline Safety

Expectations • Knowledgeable involvement of Operator in establishing assessment requirements • Significant involvement of Operator in evaluating and accepting assessment results • Thoughtful integration of assessment results with other risk factor data, with visible impacts on the excavation & remediation Plans Office of Pipeline Safety • Effective communication and use of assessment results across Operator’s organization
