The Research and Special Programs Administration (RSPA) of the Department of Transportation (DOT) is responsible for the safety of about 267,000 miles of interstate natural gas transmission pipelines. Each year several hundred pipeline incidents (i.e., ruptures and leakages) occur, often resulting in deaths and damage to property or the environment. Since most natural gas pipelines were constructed in the 1950s and 1960s, the risk of damaging incidents in these aging pipelines will only increase. To improve the safety of natural gas and hazardous liquid transmission pipelines, the Congress passed the Pipeline Safety Reauthorization Act of 1988 (P.L. 100-561, approved Oct. 31, 1988) directing DOT to (1) prepare a feasibility study on requiring the use of an instrumented internal inspection device called a 'smart pig' to inspect transmission pipelines and (2) establish regulations requiring that new or replacement pipeline facilities, to the extent practicable, be capable of accommodating smart pigs. As of mid-September 1992, the Congress was also considering new legislation that would require pipelines to be inspected with smart pigs under certain circumstances. The report focuses on the use, capabilities, and limitations of smart pig inspections; federal regulations and guidelines for smart pig inspections; and the status of RSPA's efforts to comply with P.L. 100-561.
