NTSB 101
May 15, 2015 Mayor's Council on Pipeline Safety
– Independent federal agency, investigate transportation mishaps, all modes
– Determine probable cause(s) and make recommendations to prevent recurrences
– Primary product: Safety recommendations• Favorable response > 80%
– SINGLE FOCUS IS SAFETY
– Independence• Political: Findings and recommendations based upon
evidence rather than politics• Functional: No “dog in the fight”

The Problem
May 15, 2015 Mayor's Council on Pipeline Safety
– More than 2.1 Million Miles of Gas Distribution Pipelines
– Almost 300K Miles of Gas Transmission Pipelines
– Two Aspects to the Problem• Most important: Prevention• If that fails: Emergency response
![Page 5: Pipeline Safety: How the Mayor’s Council On Pipeline Safety Can Help Presentation to: Mayor’s Council on Pipeline Safety Conference Name: Christopher A.](https://reader035.fdocuments.net/reader035/viewer/2022070404/56649f395503460f94c557ea/html5/thumbnails/5.jpg)

Prevention
May 15, 2015 Mayor's Council on Pipeline Safety
– Essential: Robust Integrity Management Program regarding• Installation• Inspection• Maintenance
– Prevention Depends More Heavily on Operators/Utilities• Regulator resources increasingly limited,
hence more risk-based• Regulators looking more at process than at
pipelines
![Page 6: Pipeline Safety: How the Mayor’s Council On Pipeline Safety Can Help Presentation to: Mayor’s Council on Pipeline Safety Conference Name: Christopher A.](https://reader035.fdocuments.net/reader035/viewer/2022070404/56649f395503460f94c557ea/html5/thumbnails/6.jpg)

Additional Prevention Challenge
May 15, 2015 Mayor's Council on Pipeline Safety
– Third-Party Damage• Major cause of pipeline damage• Depends on creating robust public
awareness
![Page 7: Pipeline Safety: How the Mayor’s Council On Pipeline Safety Can Help Presentation to: Mayor’s Council on Pipeline Safety Conference Name: Christopher A.](https://reader035.fdocuments.net/reader035/viewer/2022070404/56649f395503460f94c557ea/html5/thumbnails/7.jpg)

Emergency Response
May 15, 2015 Mayor's Council on Pipeline Safety
– Ability to Stop the Release• Automatic or remote shut-off valves• Excess flow valves
– Emergency Responders• Knowledge re pipeline• Ability to respond• Availability of nearby resources
![Page 8: Pipeline Safety: How the Mayor’s Council On Pipeline Safety Can Help Presentation to: Mayor’s Council on Pipeline Safety Conference Name: Christopher A.](https://reader035.fdocuments.net/reader035/viewer/2022070404/56649f395503460f94c557ea/html5/thumbnails/8.jpg)

Example: San Bruno
May 15, 2015 Mayor's Council on Pipeline Safety
– Faulty Installation
– Inadequate Inspection
– Inadequate Maintenance
– Shut-Off Valves Manual
– Emergency Responders Unaware
– Good News: Subsequent Progress is Encouraging

Multiple Examples: Allentown, PA
May 15, 2015 Mayor's Council on Pipeline Safety
– Allentown contains many miles of small diameter (8 inches or less) cast-iron gas and water mains installed in the late 1800’s and early 1900’s that have probably been weakened by corrosion
– 1925-1976: Two gas pipeline explosions, 10 fatalities, 24 injuries, 2 buildings destroyed
– 1976-1992: Two explosions, three fatalities, 23 injuries, 6 buildings destroyed
![Page 10: Pipeline Safety: How the Mayor’s Council On Pipeline Safety Can Help Presentation to: Mayor’s Council on Pipeline Safety Conference Name: Christopher A.](https://reader035.fdocuments.net/reader035/viewer/2022070404/56649f395503460f94c557ea/html5/thumbnails/10.jpg)

Allentown, PA (con’t)
May 15, 2015 Mayor's Council on Pipeline Safety
– 1994: Natural gas distribution pipeline explosion• Probable cause: Failure to ensure compliance with
excavation requirements through project oversight• Contributing to severity: Absence of excess flow
valve; absence of a gas detector
– 2012: Explosion of 12-inch cast iron gas main with a circumferential crack• Five fatalities, 8 homes destroyed
– 2015: Leak 3 blocks from the 2011 explosion• People smelled gas and called in the leak• 25-30 residents were evacuated

Progress
May 15, 2015 Mayor's Council on Pipeline Safety
Kudos to Mayor Pawlowski -- and others --for keeping the pressure on
Accidents: A mix of causes, including but not limited to older infrastructure
Before 2011: Utility replaced 9.3 mi. of cast iron pipe per year
2013: Utility replaced 63 miles
But utility replacement schedule is 2027 for all cast iron pipes, 2043 for bare steel

Other Examples
May 15, 2015 Mayor's Council on Pipeline Safety
– Palm City, FL, 2009• Probable cause: Cracking under a disbonded
polyethylene coating that remained undetected by the integrity management program
– Sissonville, WV, 2012– Probable cause: External corrosion due to
deteriorated coating and ineffective cathodic protection, and the failure to detect the corrosion because the pipeline was not inspected after 1988
– Explosion and Fire in New York City, 2014• Currently under investigation• Public docket now open• Probable cause meeting, June 2015

Integrity Management Programs
May 15, 2015 Mayor's Council on Pipeline Safety
– 2004: PHMSA required Integrity Management Programs to manage risk in gas transmission pipelines in High Consequence Areas (HCAs)
– Implementing Integrity Management Programs, however, is not trivial
– 2015 NTSB Safety Study: No evidence that IM programs reduced incidence of events; Recommendations included:• Increased coordination among state inspectors, and
between state inspectors and PHMSA• Improved training and guidance• Increased use of in-line inspection• More and better data collection/integration

How the Mayor’s Council Can Help
May 15, 2015 Mayor's Council on Pipeline Safety
– Keep the pressure on
– Public awareness• Call before digging• Report leaks
– Know what pipelines run through your city
– Emergency responder relationship with operator/utility
– Advocacy

Conclusions
May 15, 2015 Mayor's Council on Pipeline Safety
– Efforts to identify and mitigate risks must be• More systematic• More effective at every level
– Needed:• Better inline assessment tools• Better federal/state coordination• Better federal oversight• BETTER DATA!
