National Transportation Safety Board (NTSB) released a study on integrity management of gas transmission pipelines in high consequence
areas. The agency reports integrity management involves the process by which
pipeline operators and inspectors find and address problems before they result
in incidents. The study includes recommendations on various improvements, which
include a broadened use of in-line inspection, the inspection method that
detects the most potential problem areas per mile of pipeline.
In addition, the
agency recommends closer state-to-state and federal-state cooperation among
inspectors, and calls for expanded and improved resources and guidance at the
federal level, including improvements to the National Pipeline Mapping System
and better integration of geographic information system technology.
