Nearly half a million miles of oil and natural gas transmission pipeline criss-cross the United States. While an efficient and fundamentally safe means of transport, many pipelines carry hazardous materials with the potential to cause public injury and environmental damage. The nation's pipeline networks are also widespread, running alternately through remote and densely populated regions; consequently, these systems are vulnerable to accidents and terrorist attack. This book explores how the various elements of U.S. pipeline safety and security activity fit together in the nation's overall strategy to protect transportation infrastructure.

Nearly half a million miles of oil and gas transmission pipeline crisscross the United States. While an efficient and fundamentally safe means of transport, many pipelines carry hazardous materials with the potential to cause public injury and environmental damage. The nation's pipeline networks are also widespread, running alternately through remote and densely populated regions; consequently, these systems are vulnerable to accidents and terrorist attack. The 109th Congress passed the Pipeline Safety Improvement Act of 2006 (P.L. 109-468) to improve pipeline safety and security practices, and to reauthorize the federal Office of Pipeline Safety. The 110th Congress is overseeing the implementation of the act and examining ongoing policy issues related to the nation's pipeline network. The Surface Transportation and Rail Security Act of 2007 (S. 184) would require federal plans for critical pipeline security and incident recovery, and would mandate pipeline security inspections and enforcement. The Office of Pipeline Safety (OPS), within the Department of Transportation (DOT), is the lead federal regulator of pipeline safety. The OPS uses a variety of strategies to promote compliance with its safety regulations, including inspections, investigation of safety incidents, and maintaining a dialogue with pipeline operators. The agency clarifies its regulatory expectations through a range of communications and relies upon a range of enforcement actions to ensure that pipeline operators correct safety violations and take preventive measures to preclude future problems. The Transportation Security Administration (TSA), within the Department of Homeland Security (DHS), is the lead federal agency for security in all modes of transportation -- including pipelines. The agency oversees industry's identification and protection of pipelines by developing security standards; implementing measures to mitigate security risk; building stakeholder relations; and monitoring compliance with security standards, requirements, and regulation. While the OPS and TSA have distinct missions, pipeline safety and security are intertwined. Federal activities in pipeline safety and security are evolving. Although pipeline impacts on the environment remain a concern of some public interest groups, both federal government and industry representatives suggest that federal pipeline programs have been on the right track. As oversight of the federal role in pipeline safety and security continues, Congress may focus on the effectiveness of state pipeline damage prevention programs, the promulgation of low-stress pipeline regulations, federal pipeline safety enforcement, and the relationship between DHS and the DOT with respect to pipeline security, among other provisions in federal pipeline safety regulation. In addition to these specific issues, Congress may wish to assess how the various elements of U.S. pipeline safety and security activity fit together in the nation's overall strategy to protect transportation infrastructure. This report will be updated as events warrant.

This report covers ways in which the 112th Congress can introduce relevant legislation to safeguard pipelines that transport natural gas, oil, and other hazardous liquids across the United States. While an efficient and fundamentally safe means of transport, many pipelines carry materials with the potential to cause public injury and environmental damage; the networks are also widespread and vulnerable to accidents and terrorist attack.

This report discusses congressional interest in securing the nation's pipelines. Nearly half a million miles of oil and natural gas transmission pipeline crisscross the United States. While an efficient and fundamentally safe means of transport, many pipelines carry hazardous materials with the potential to cause public injury and environmental damage.

The Office of Pipeline Safety (OPS) is implementing a new approach to overseeing the safety of a 2.2-million-mile network of pipelines in the United States that transports potentially dangerous materials, including hazardous liquids, such as oil and natural gas. OPS has to complete several important steps to implement its integrity management approach within an ambitious, self-imposed schedule. The agency began applying this new regulatory approach to hazardous liquid pipelines in 2000 by issuing final rules requiring operators of these pipelines to develop integrity management programs. While implementing its integrity management approach, OPS must also perform ongoing oversight duties, such as inspecting the construction of new pipelines and investigating pipeline incidents. In addition to meeting its ambitious schedule, OPS faces a number of other challenges in implementing this new regulatory approach. These challenges include (1) enforcing the integrity management requirements consistently and effectively, (2) ensuring that natural gas transmission pipeline operators use assessment methods appropriately, (3) establishing an inspection interval for natural gas transmission pipelines, (4) measuring and reporting on the effectiveness of the approach, and (5) developing and implementing an approach for overseeing pipeline security. OPS's efforts to identify the resources and expertise needed to implement its integrity management approach are hampered by the lack of an up-to-date assessment of current and future staffing and training needs and an examination of the workforce's deployment across the organization--essential elements of a "workforce plan."
