Pipeline Safety:Collecting Data and Sharing Information on Federally Unregulated Gathering Pipelines Could Help Enhance Safety
GAO-12-388: Published: Mar 22, 2012. Publicly Released: Mar 22, 2012.
While the safety risks of onshore gathering pipelines that are not regulated by PHMSA are generally considered to be lower than for other types of pipelines, PHMSA does not collect comprehensive data to identify the safety risks of unregulated gathering pipelines. In response to a GAO survey, state pipeline safety agencies cited construction quality, maintenance practices, unknown or uncertain loc...
Safety Effects of Less Prescriptive Requirements for Low-Stress Natural Gas Transmission Pipelines Are Uncertain
GAO-12-389R: Published: Feb 16, 2012. Publicly Released: Feb 16, 2012.
Applying PHMSAs new distribution integrity management requirements to low-stress transmission pipelines would result in less prescriptive safety requirements for these pipelines. Overall, requirements for distribution pipelines are less prescriptive than requirements for transmission pipelines in part because the former operate at lower pressure and pose lower risks in general than the latte...
Undeclared Hazardous Materials: New DOT Efforts May Provide Additional Information on Undeclared Shipments
GAO-06-471: Published: Mar 29, 2006. Publicly Released: Mar 29, 2006.
More than 3 billion tons of regulated hazardous materials (hazmat)--including explosive, poisonous, corrosive, flammable, and radioactive materials--are transported in the United States each year. When these materials are properly packaged, labeled, and stowed, they can be transported safely, but when they are not, they can pose significant threats to transportation workers, emergency responders,...
