【 摘 要 】

A letter report issued by the Government Accountability Office with an abstract that begins "The Pipeline Safety Improvement Act of 2002 established a risk-based program for gas transmission pipelines--the integrity management program. The program requires operators of natural and other gas transmission pipelines to identify "high consequence areas" where pipeline incidents would most severely affect public safety, such as those occurring in highly populated or frequented areas. Operators must assess pipelines in these areas for safety risks and repair or replace any defective segments. Operators must also submit data on performance measures to the Pipeline and Hazardous Materials Safety Administration (PHMSA). The 2002 act also directed GAO to assess this program's effects on public safety. Accordingly, we examined (1) the effect on public safety of the integrity management program and (2) PHMSA and state pipeline agencies' plans to oversee operators' implementation of program requirements. To fulfill these objectives, GAO interviewed 51 gas pipeline operators and surveyed all state pipeline agencies."
