The Department of Energy's first Quadrennial Energy Review (QER), released in 2015, also highlighted pipeline safety as a growing concern for the nation's energy infrastructure. The federal pipeline safety program resides primarily within the Department of Transportation's (DOT's) Pipeline and Hazardous Materials Safety Administration (PHMSA), although its inspection and enforcement activities rely heavily upon partnerships with the states. Pipeline Network

The U.S. energy pipeline network is composed of approximately 3 million miles of pipeline transporting natural gas, oil, and hazardous liquids ( Table 1 ). The National Transportation Safety Board (NTSB) investigates transportation accidents—including pipeline accidents—and issues associated safety recommendations. For FY2019, PHMSA's estimated budget authority is approximately $164 million—more than double the agency's budget authority in FY2008 (not adjusted for inflation). The Trump Administration's requested budget authority for PHMSA is approximately $151 million for FY2020, roughly 8% less than the FY2019 budget authority, with proposed reductions primarily in contract programs, research and development, and grants to states. The NTSB issued eight recommendations to the Secretary of Transportation and PHMSA, including
auditing the business practices of PHMSA's onshore pipeline facility response plan programs, including reviews of response plans and drill programs, to correct deficiencies, allocating sufficient resources to ensure that PHMSA's facility response plan program meets all of the requirements of the Oil Pollution Act of 1990, clarifying and strengthening federal regulation related to the identification and repair of pipeline crack defects, issuing advisory bulletins to all hazardous liquid and natural gas pipeline operators describing the circumstances of the accident in Marshall, asking them to take appropriate action to eliminate similar deficiencies, to identify deficiencies in facility response plans, and to update these plans as necessary, developing requirements for team training of control center staff involved in pipeline operations similar to those used in other transportation modes, strengthening operator qualification requirements, and harmonizing onshore oil pipeline response planning requirements with those of the U.S. Coast Guard and the U.S. Environmental Protection Agency for oil and petroleum products facilities to ensure that operators have adequate resources for worst-case discharges. Nonetheless, pipeline safety and security are intertwined in some respects—and PHMSA is involved in both. Overdue PHMSA Statutory Mandates

Congress has used reauthorizations to impose on PHMSA various mandates regarding standards, studies, and other elements of pipeline safety regulation—usually in response to major pipeline accidents. The Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 ( P.L. 112-90 ) and the PIPES Act of 2016 ( P.L. 114-183 ) together included 61 such mandates. As of March 5, 2019, according to PHMSA, the agency had completed 34 of 42 mandates under P.L. 112-90 and 16 of 19 mandates under P.L. 114-183 . State Pipeline Safety Program Oversight

In the wake of several major safety incidents involving facilities under the jurisdiction of state pipeline safety regulators, some state programs have come under scrutiny regarding their overall effectiveness. Likewise, Congress has ongoing concern about the safety of older transmission pipelines—a key factor in San Bruno—and in the replacement of leaky and deteriorating cast iron pipe in natural gas distribution systems—a key factor in Merrimack Valley. The Merrimack Valley incident may refocus attention on PHMSA's regulation of pipe replacement (currently voluntary), pipeline modernization projects and work packages, older pipeline records, safety management systems, and other issues related to aging pipelines. PHMSA and Pipeline Security

Ongoing physical and cyber threats against the nation's pipelines since passage of the PIPES Act have heightened concerns about the security risks to these pipelines. While PHMSA reports cooperation with TSA in pipeline security under the terms of the pipeline security annex and subsequent collaboration, questions remain regarding exactly what this cooperation entails and the ongoing roles of the two agencies. In addition to the specific issues highlighted in this report, Congress may assess how the various elements of U.S. pipeline safety activity fit together in the nation's overall strategy to protect the public and the environment. Pipeline safety necessarily involves various groups: federal and state agencies, pipeline associations, large and small pipeline operators, and local communities. Reviewing how these groups work together to achieve common goals could be an overarching concern for Congress.
The U.S. energy pipeline network is composed of approximately 3 million miles of pipeline transporting natural gas, oil, and other hazardous liquids. Recent incidents in California, Pennsylvania, Massachusetts, and other states have drawn criticism from stakeholders and have raised concerns in Congress about pipeline safety. The Department of Energy's (DOE's) 2015 Quadrennial Energy Review also highlighted pipeline safety as an issue for the nation's energy infrastructure. Recent incident statistics suggest there is opportunity for safety improvement.
The federal pipeline safety program is administered by the Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA), which relies heavily on state partnerships for inspection and enforcement of its regulations. PHMSA's pipeline safety program is authorized through FY2019. For FY2019, PHMSA's estimated budget authority is approximately $164 million—more than double the agency's budget authority in FY2008 (not adjusted for inflation). Much of PHMSA's funding is for inspectors. However, due to private sector competition, the agency faces persistent challenges recruiting and retaining the staff for which it is funded. The Trump Administration's requested budget authority for PHMSA is approximately $151 million for FY2020, roughly 8% less than the FY2019 amount. The request would only slightly reduce PHMSA staffing but proposes cuts in state grants that could impact staffing at state pipeline safety agencies. In the wake of major incidents involving facilities under state jurisdiction, some state programs have come under scrutiny regarding their effectiveness and oversight by PHMSA.
Congress has used past reauthorizations to impose various mandates on PHMSA regarding standards, studies, and other elements of pipeline safety regulation. The Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (P.L. 112-90) and the PIPES Act of 2016 (P.L. 114-183) together included 61 such mandates. As of March 5, 2019, according to PHMSA, the agency had completed 34 of 42 mandates under P.L. 112-90 and 16 of 19 mandates under P.L. 114-183. PHMSA also has not satisfied a number of safety recommendations from the National Transportation Safety Board (NTSB). Some in Congress are concerned that major mandates and NTSB recommendations remain unfulfilled.
The NTSB highlighted aging pipelines as a particular concern in its 2019-2020 Most Wanted List of Transportation Safety Improvements. Likewise, Congress has ongoing interest in the safety of older transmission pipelines and in the replacement of leaky and deteriorating cast iron pipe in natural gas distribution systems. Recent accidents involving older pipelines and related infrastructure may refocus attention on PHMSA's regulation of pipe replacement (currently voluntary), pipeline modernization projects and work packages, older pipeline records, safety management systems, and other issues related to aging pipelines.
Ongoing physical and cyber threats against the nation's pipelines since passage of the PIPES Act have heightened concerns about pipeline security risks. Although the Transportation Security Administration (TSA) has the primary statutory authority over pipeline security, pipeline safety and security are intertwined—and PHMSA is involved in both. Under the terms of a 2006 agreement, PHMSA and TSA are directed to work together "to delineate clear lines of authority … in the area of transportation security." While PHMSA reports ongoing cooperation with TSA, questions remain about what this cooperation entails and the ongoing roles of the two agencies.
In addition to these specific issues, Congress may assess how the various elements of U.S. pipeline safety and security fit together in the nation's overall approach to protect the public and the environment. This approach involves federal and state agencies, pipeline associations, large and small pipeline operators, and local communities. Reviewing how these various groups work together to achieve common goals could be an overarching consideration for Congress.
