This presentation by Richard B. Kuprewicz, President of Accufacts, Inc., focuses on key issues affecting gas transmission pipeline safety. It highlights the need for improved Gas Transmission Integrity Management (IM) regulations and the responsibilities of operators. Kuprewicz criticizes current IM practices and emphasizes the importance of transparency, effective assessment methods, and proper record-keeping. The presentation calls for regulatory improvements to enhance public confidence in pipeline safety, discussing the implications of current practices and potential reforms needed to ensure the integrity of America's pipelines.

Presentation to NARUCFebruary 14, 2011 Accufcats Final Pipeline Safety: Keeping America’s Pipelines Safe and Secure By Richard B. Kuprewicz, President, Accufacts Inc.
Today’s Presentation • Focus Today on Gas Transmission Pipelines • Too early to judge DIMP (distribution regs) effectiveness • Based on Information Readily Available and In the Public Domain • Long Record of Providing Neutral Perspective • Audience can either listen or “spin” Accufcats Final
On the Regulatory Front • Something Terribly Wrong with Current Gas Transmission Integrity Management (“IM”) Applications • IM Regs very clear “It’s the gas pipeline operator’s responsibility!” • Operator must integrate, demonstrate, and back up IM decisions/program • “Oops, Whoops, We didn’t know” or “Can’t find the records” not a defense • PHMSA Advisory Bulletin ADB 11-01 • Suggests a problem with more than one operator • Fully support bulletin and PHMSA on this important matter • Gas Transmission IM Regulatory Improvements Needed • Industry has had almost ten years to get right, • or get wrong! Accufcats Final
Critical Gas Transmission IM Issues • Assessment Methods (Inspections) Used, Need to Be Public • All assessment methods have strengths and weaknesses • Some “internal inspections” can be really dumb, others really smart • Depends on the risk and the pipeline • No past history of a “proper pressure” (hydrotest) can be very bad. • Forget the “pressure reversal” boogeyman diversion • Pressure testing with gas in wrong area can be very bad • The NTSB Urgent Recommendations and hydrotesting got it right • Direct assessment has very limited applications • Use of “other technologies” places burden on the operator to demonstrate • Very rare for operator to rely on just one assessment method • IM Regulations specifically warn against use of one method • Pressure Spiking At-Risk Pipe!! • Tends to fail as rupture on a gas transmission pipeline • Apparent perversion of IM intent Accufcats Final
Gas Transmission IM & Transparency • How MAOP is determined and confidence? • Can’t quickly find these critical records! • Is the “safety factor” real? • Need to eliminate over pressure reporting waiver in 191.23(b)(4) • For steel transmission pipelines • Age is not the relevant issue • Vintage, however, can determine various risks • More missing records??? • Need public reporting of assessment methods, findings, and conditions • Report conditions/repairs in both HCAS and Non-HCAs • By risks found, time to repair condition, by state • Risk Management must have proper reporting to regulator and to public – or forget this approach Accufcats Final
Important Regulatory Observations • Remote or Automatic Closure Valves • Public discussion on applying to “exotic” pipelines warranted • > 24 inch transmission pipelines • Population and valve spacing very important • Laws of rupture science will provide proper guidance • Forget C-fer correlation for “exotics” • Rate Setting Function Needs to be Separated from Pipeline Safety Organizations • Inherent conflict of interest • Costs of “safety” overstated • Cost of “failures” understated • Self Regulated = Oxymoron • At Stake – Public Confidence and Credibility in This Important Infrastructure • Cannot support recent bills for PHMSA reauthorization • Technically flawed and illusionary safeties • Need to address the real gas transmission regulatory gaps Accufcats Final
