8 JUNE 2018 W W W.MATERIALSPERFORMANCE.COM CORROSION MANAGEMENT FOR PIPELINE INTEGRIT Y SUPPLEMENT TO MP PHMSA Promotes Hazmat Accident Investigation Team Pilot Program As part of its continuing ef forts to improve safety, the U.S. Department of Transportation's (DOT) Pipeline and Haz- ardous Materials Safety Administration (PHMSA) (Washington, DC, USA) is pro- moting its hazardous materials Accident Investigation Team (AIT) pilot program to hazmat and emergency first responder stakeholders. The one-year AIT pilot program was launch ed in O ctober 2017 by PHMSA's O f f i c e of Ha z a rd o u s Ma t e r i a l s S a fe ty (O H MS ) Fi el d O p eration s D iv i si on to develop a comprehensive investigative pro- cess for significant hazmat accidents and incidents, and is fundamentally different from traditional PHMSA hazardous materi- als regulation enforcement efforts. The AIT is charged with uncovering and analyzing the series of events that lead to severe acci- dents, and this investigative process will identify contributing and root causes so past mistakes can be used to help forecast and mitigate future hazmat accidents. Th e O H MS pl ay s a criti cal ro l e in PHMSA's mission—to protect people and the environment by advancing the safe transportation of energy and hazardous materials—by ensuring compliance with federal hazardous materials regulations. The underlying causes of severe hazardous mat erial s accidents, howe ver, can't b e addressed by compliance and enforcement efforts alone. The AIT will examine and provide recommendations on the feasibility and viability of a robust, long-term OHMS accident investigation program. Objectives are to improve accuracy and relevance of PHMSA data collection efforts through root cause analysis; identify emerging risks and recommend agency action (i.e., outreach, engagement, rulemaking, etc.); enhance risk analysis through innovative, data- driven tracking of emerging trends and near misses; and share accident data rec- ommendations and lessons learned with internal and external stakeholders, includ- ing D OT modal partners (other surface transportation administrations across the DOT, such as the Federal Highway Adminis- trati on , Fe d eral Mo tor C a r r i er S afe ty Administration, Federal Railroad Adminis- tration, Federal Transit Administration, Maritime Administration, and the National Highway Traffic Safety Administration). Numerous benefits are anticipated , such as advancing the quality of investiga- tions by strengthening full-time investiga- tor expertise through comprehensive root cause analysis training; determining robust standardized processes to improve data collection, analysis, and validation ; and strengthening stakeholder outreach efforts and partnerships with DOT modal partners and external stakeholders.

A section of pipe separated into four pieces, including this 21.7-ft (6.6-m) section, when Columbia Gas Transmission Pipeline 1278 failed near Milford, Pennsylvania, USA, on November 5, 2008. The pipeline failure resulted in a rupture that involved three lengths of pipe in a wetland area. The failure was caused by near-neutral-pH stress corrosion cracking identified by an investigative consultant.
