Pipeline Safety: Department of Transportation Needs to Complete Regulatory, Data, and Guidance Efforts
GAO-15-843T: Published: Sep 29, 2015. Publicly Released: Sep 29, 2015.
The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has begun but not completed efforts to improve pipeline safety in response to GAO's prior recommendations:Gathering pipelines : In 2012, GAO found that while gathering pipelines that are not regulated by PHMSA were generally considered to present less safety risk than other pipelines, PHMSA did...
Gas Pipeline Safety: Guidance and More Information Needed before Using Risk-Based Reassessment Intervals
GAO-13-577: Published: Jun 27, 2013. Publicly Released: Jun 27, 2013.
Baseline assessment and reassessment data collected by the Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) since 2004 show that pipeline operators are making repairs in highly populated or frequented areas ("high consequence areas"). For example, from 2004 to 2009, operators made 1,080 immediate repairs. While operators can use assessment data to...
Pipeline Permitting: Interstate and Intrastate Natural Gas Permitting Processes Include Multiple Steps, and Time Frames Vary
GAO-13-221: Published: Feb 15, 2013. Publicly Released: Feb 15, 2013.
Both the interstate and intrastate natural gas pipeline permitting processes are complex and can involve multiple federal, state, and local agencies, as well as public interest groups and citizens, and include multiple steps. The interstate process involves a voluntary pre-filing phase, an application phase, and a post-authorization phase with multiple steps that stakeholders reported to be consis...
Pipeline Safety: Better Data and Guidance Could Improve Operators' Responses to Incidents
GAO-13-284T: Published: Jan 28, 2013. Publicly Released: Jan 28, 2013.
Numerous variables--some of which are under operators' control--influence the ability of transmission pipeline operators to respond to incidents. For example, the location of response personnel and the use of manual or automated valves can affect the amount of time it takes for operators to respond to incidents. However, because the advantages and disadvantages of installing an automated valve are...
Safety Effects of Less Prescriptive Requirements for Low-Stress Natural Gas Transmission Pipelines Are Uncertain
GAO-12-389R: Published: Feb 16, 2012. Publicly Released: Feb 16, 2012.
Applying PHMSAs new distribution integrity management requirements to low-stress transmission pipelines would result in less prescriptive safety requirements for these pipelines. Overall, requirements for distribution pipelines are less prescriptive than requirements for transmission pipelines in part because the former operate at lower pressure and pose lower risks in general than the latte...
Gas Pipeline Safety: Views on Proposed Legislation to Reauthorize Pipeline Safety Provisions
GAO-06-1027T: Published: Aug 4, 2006. Publicly Released: Aug 4, 2006.
The Pipeline Safety Improvement Act of 2002 established a risk-based program for gas transmission pipelines--termed integrity management--which requires pipeline operators to identify areas where the consequences of a pipeline incident would be the greatest, such as highly populated areas. Operators must assess pipelines in these areas for safety threats (such as corrosion), repair or replace defe...
Trans-Alaska Pipeline: Actions to Improve Safety Are Under Way
RCED-95-162: Published: Aug 1, 1995. Publicly Released: Aug 8, 1995.
Pursuant to a congressional request, GAO provided information on the progress made in correcting deficiencies in the operation and management of the Trans-Alaska Pipeline System (TAPS), focusing on: (1) whether the planned corrective actions will address deficiencies in the pipeline's electrical systems, quality, and preventive maintenance; (2) whether regulators are taking action to improve overs...
Oil Reserve: Some Concerns Remain About SPR Drawdown and Distribution
RCED-91-16: Published: Nov 28, 1990. Publicly Released: Jan 18, 1991.
Pursuant to a congressional request, GAO examined the Department of Energy's (DOE) Strategic Petroleum Reserve (SPR) drawdown plans, focusing on: (1) DOE capability for withdrawing and distributing SPR oil; (2) SPR compliance with pipeline safety requirements; and (3) the status of DOE actions to correct problems previously identified by GAO.GAO found that: (1) DOE estimated that it could withdraw...
Energy Management: Extent of Crude Oil Contamination Is Uncertain
RCED-90-114BR: Published: Mar 8, 1990. Publicly Released: Apr 13, 1990.
Pursuant to a congressional request, GAO reviewed allegations of crude oil contamination, focusing on: (1) the extent and types of contamination; (2) how environmental legislation has affected the contamination issue; and (3) corrective actions that the government and the oil industry have taken concerning crude oil contamination.GAO found that: (1) oil industry officials identified 40 cases of cr...
