NTSB Safety Recommendations P-09-1 through -3

************************************************************

The National Transportation Safety Board makes the following

recommendations to the Pipeline and Hazardous Materials

Safety Administration:

Conduct a comprehensive study to identify actions that can

be implemented by pipeline operators to eliminate

catastrophic longitudinal seam failures in electric

resistance welded pipe (ERW); at a minimum, the study should

include assessments of the effectiveness and effects of in-

line inspection tools, hydrostatic pressure tests, and spike

pressure tests; pipe material strength characteristics and

failure mechanisms; the effects of aging on ERW pipelines;

operational factors; and data collection and predictive

analysis. (P-09-1)

Based on the results of the study requested in Safety

Recommendation P-09-1, implement the actions needed. (P-09-

2)

Initiate a program to evaluate pipeline operators' public

education programs, including pipeline operators' self-

evaluations of the effectiveness of their public education

programs. Provide the National Transportation Safety Board

with a timeline for implementation and completion of this

evaluation. (P-09-3)
