This CRS report focuses on pipeline safety and security. "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. [...] 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."
