【 摘 要 】

A letter report issued by the Government Accountability Office with an abstract that begins "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 locations, and limited or no information on pipeline integrity as among the highest risks for federally unregulated pipelines. Without data on these risk factors, pipeline safety officials are unable to assess and manage safety risks associated with these pipelines. Furthermore, changes in pipeline operational environments cited in response to GAO’s survey and by industry officials could also increase safety risks for federally unregulated gathering pipelines. Specifically, land-use changes are resulting in development encroaching on existing pipelines and the increased extraction of oil and natural gas from shale deposits is resulting in the development of new gathering pipelines, some of which are larger in diameter and operate at higher pressure than older pipelines. PHMSA is considering collecting data on federally unregulated gathering pipelines, but the agency’s plans are preliminary, and the extent to which PHMSA will collect data sufficient to evaluate the potential safety risks associated with these pipelines is uncertain."
