Baseline Assessment Plan Protocol Review Integrity Management Workshop July 23-34, 2002
Program Element Requirement • §452 (f) An operator must include, at minimum, each of the following elements in its written integrity management program: • (2) A baseline assessment plan meeting the requirements of paragraph (c) of this section.
Objectives • Verify Baseline Assessment Plan Completion • Verify Assessment Method Selection • Verify Assessment Schedule • Verify Risk Basis • Verify Implementation, including Compliance Deadlines
Baseline Assessment Plan • Initial Issuance • Documentation • Review Method/Process • Compliance Deadline (March 31, 2002)
Baseline Assessment Plan • Completeness • All Segments Included • All Segments Risk Ranked • All Segments Scheduled • Assessment Method for All Segments
Baseline Assessment Plan • Updates and Revision Control • Documentation of Revisions • Including Reasons for Changes • Change Plan Prior to Implementation • Incorporate All Needed Changes • Additions, Deletions or Reductions in Segment Size • Additional HCAs • Changes Based on Risk Analysis
Baseline Assessment Plan • Assessment Methods • Address Integrity Threats • Corrosion • Outside Force Damage • Cracks (If Applicable)
Baseline Assessment Plan • Assessment Methods • Utilize Risk Analysis/Information Analysis • Consideration of All Risk Factors • Select Best Tool(s) or Hydrostatic Test to Address Risks
Baseline Assessment Plan • ILI Inspection (Specific Tool Identification) • Tool Types • Geometry Tools • Metal Loss Tools • Crack Tools • Tool Capabilities • Defect Identification • Defect Characterization • Tool Technology • MFL (Low Resolution – High Resolution – Transverse) • UT (Compression Wave – Shear Wave)
Baseline Assessment Plan • Low-Frequency ERW or Lap Welded Pipe • Susceptible to Seam Failures • All Pre-1970 Pipe Considered Susceptible • Justifications to Contrary will be Reviewed • Technical Basis Held to High Standards • LF-ERW or LW Pipe Assessments • Hydrostatic Test • Transverse MFL Tool
Baseline Assessment Plan • Hydrostatic Pressure Test • Comply with Subpart E • Spike Test May be Included In Addition
Baseline Assessment Plan • Use of “Other” Technology • Other Technologies • (e.g., Direct Assessment) • Notification • 90-Day Prior to Use
Baseline Assessment Plan • Assessment Schedule • Each Segment Scheduled • Risk Basis Documented • Progress Deadline • 50% of Mileage by 9/30/04 (Large Operators) • Emphasis on Highest Risk Segments • Completion Deadline • 100% of Mileage by 3/31/08 (Large Operators) • Progress To Date
Baseline Assessment Plan • Prior Assessments • January 1, 1996 (Large Operators) • February 15, 1997 (Small Operators) • Meet Current Requirements • Equivalent Understanding of P/L Integrity • Addressed Integrity Risks • Remediation Complied with Current Criteria • 180 Day Discovery Begins Upon Declaration of the Prior Assessment as a Baseline Assessment (NLT 3/31/02 Lg Oper )
Information Collection • Assessment Status (Scheduled vs. Actual) • Expressed as Mileage Completed and as Percentage of Total Mileage • Breakdown by State • Breakdown by Type of Inspection/Tool Type • ILI Tool Type (Hi-Res MFL, Lo-Res MFL, Comp. UT, Shear UT, TFI, Geometry, Other ILI) • Hydrostatic Pressure Test • Other Technology
Baseline Assessment Plan • Expectations • Operators are Expected to Take a Technically Sound Approach to Assess and Understand the Integrity of All Segments that Could Affect HCAs • Address Integrity Risk Factors • Appropriate Assessment Methods/Tools • Assure Plan Implementation • Schedule Compliance
