Pipeline Safety, Regulatory Certainty, and Job Creation Act
• Drafted by Congress and signed into law by the President on January 3, 2012
• Reauthorization of Pipeline Safety Program– Stronger enforcement tools
– Increases civil penalties

Girth Welds with Low Tensile Strain Capacity
• Recent incidents:– Vintage girth welds
– Pre-existing hydrogen-assisted WM/HAZ cracks
– Evidence of little or no plastic deformation
• Codes have no requirement for girth weld tensile strain capacity

U.S. Department of TransportationPipeline and Hazardous Materials Safety Administration
High Axial Tensile Strain
• Recent incidents:– Ground movement
– Slopes with wet clay soils
– Rising water table & pipe buoyancy
• Pipeline operators should evaluate and mitigate this risk. Methods may include:– Preventing pipeline movement
– Monitoring pipeline movement
– Removing/reinforcing girth welds with low strain capacity
