    5. 5. MAOP Verification PHMSA GuidanceApril 22, 1998 - PHMSA 1998 Guidance Document –Determination of Maximum Allowable Operating Pressure inNatural Gas Pipelines September 9, 2010 – San Bruno Pipeline RuptureJanuary 10, 2011 - PHMSA Advisory Bulletin (ADB-11-01) -Establishing Maximum Allowable Operating Pressure UsingRecord Evidence (source of “Traceable, Verifiable andComplete” and “ensure company records accurately reflectthe pipelines physical and operational characteristics”) Best Practices of an MAOP Verification Program- SLIDE 5
    6. 6. MAOP Verification PHMSA GuidanceMay 7, 2012 - PHMSA Advisory Bulletin (ADB-12-06) –Verification of Records Establishing MAOP and MOPTraceable = clearly linked to original informationVerifiable = confirmed by other complementary, butseparate, documentation.Complete = finalized as evidenced by signature, date orother appropriate markingOperators to submit data via the 2013 Annual ReportPHMSA intends to act on NTSB recommendation to eliminatethe Grandfather Clause Best Practices of an MAOP Verification Program- SLIDE 6

    8. 8. Best Practices of an MAOP Verification Program- SLIDE 8
    9. 9. MAOP Project - SCOPE OptionsScope of Effort Benefit ConcernsOnly Class 3 and Class 4 Limited Scope may result Ongoing evaluationlocations and Class 1 and in faster completion of required for class locationClass 2 high consequence evaluation changes and new HCAs.areas.All Transmission No ongoing evaluation of Completion may take class locations and new longer. HCAs required. More verified knowledge of system.New Construction Evaluate whether existing processes are adequate. Eliminate future MAOP verification re-work!!!!Non-MAOP data Efficiency, only 1 review of May impact schedule records Best Practices of an MAOP Verification Program- SLIDE 9

    11. 11. MAOP Criteria• Design Criteria – Pipe• Design Criteria – Standard Fittings (e.g. elbows, tees)• Design Criteria – valves, flanges, fittings• Pressure Test – constructed prior to November 1970• Pressure Test – constructed after November 1970• Historic Operating Pressure – 5 yrs. preceding July 1, 1970• Maximum Safe Pressure• Subpart K Uprates• §192.611 provisions for change in class location and confirmation of MAOP• State Specific Requirements?????? Best Practices of an MAOP Verification Program- SLIDE 11

    14. 14. Illustration of Key Data required to support MAOP • Current Class Location • Component nominal outside • Current Pipeline MAOP diameter • • Component ASA/ASME/ANSI Date of Operation Rating • Converted under 192.14? • Component Max Working • Pipe Grade Pressure • Pipe Nominal Outside • Road crossing or encroachment Diameter with no casing? • Pipe Wall Thickness • Railroad crossing or • encroachment with no casing? Pipe Longitudinal Joint Type • Supported by bridge? • Component Type (e.g. Valve, • Compressor Station, Regulating Flange, Elbow) Station, or Metering Station? • Component Grade • Component wall thickness Best Practices of an MAOP Verification Program- SLIDE 14
    15. 15. Illustration of Key Data required to support MAOP • Minimum Actual Test Pressure • Recording Chart or Record of • Pressure Test Date Pressure Readings? • Operator Name at • Highest Elevation Construction • Lowest Elevation • Name of Operators employee • Recorder Elevation responsible for making • Leaks and Failures & pressure test Disposition noted • Name of any Test Company • Date that Historic Operating used Pressure was recorded • Test Medium Used • Historic Operating Pressure • Test Duration • Uprate Test Date • Uprate Test Pressure Best Practices of an MAOP Verification Program- SLIDE 15

    19. 19. Identification of Valid and “Verified” Record Sources? Best Source – Consider Verified if confirmed by other 1 complementary record. Illustrative example Acceptable Source – Consider Verified if confirmed by only 2 other complementary record. May be used as a complementary record. May only be used as a complementary record. 3 4 May not be used Practices of an MAOP Verification Program- SLIDE 19 Best

    23. 23. Scanning Records• ADB-12-06 requires traceable records linked to original info• The benefit of scanning applicable records is to avoid future loss and establish easier traceability.• Scanned Images should reside on a server that is backed up for data loss prevention and security.• Establish protocols for moving, scanning and returning records; this is yet another opportunity to loose key records!• Avoid confusion, only scan the targeted records you need.• Consider pre-sorting records Best Practices of an MAOP Verification Program- SLIDE 23
    24. 24. Scanning Records• Establish metadata system to capture key aspects of every image (e.g. Pipeline #, Project Number, Document Type, Date, Unique ID #, etc.)• Establish rules for color vs. black and white, two-sided originals, scan resolution, format type, continuity of stapled documents, etc.• Index each image in a logical manner; consider linking data to the associated image in some manner.• Consider following same protocol for new construction records.
