Pipeline Security

The United States depends on avast network of pipelines to transport energy. GAO was asked to review the Transportation Security Administration's (TSA) efforts to help ensure pipeline security. This report addresses the extent to which TSA's Pipeline Security Division (PSD) has (1) assessed risk and prioritized efforts to help strengthen pipeline security, (2) implemented agency guidance and requirements of the Implementing Recommendations of the 9/11 Commission Act of 2007 (9/11 Commission Act) regarding pipeline security, and (3) measured its performance in strengthening pipeline security. GAO reviewed PSD's risk assessment process and performance measures and observed 14 PSD reviews and inspections scheduled during the period of GAO's review. Although these observations are not generalizable, they provided GAO an understanding of how PSD conducts reviews and inspections. GAO recommends that TSA, among other things, establish time frames for improving risk model data, document its method for scheduling reviews, develop a plan for transmitting recommendations to operators, follow up on its recommendations, include performance measures linked to objectives in its pipeline strategy, and develop more outcome measures. DHS concurred with the recommendations and discussed planned actions, but not all will fully address the recommendations, as discussed in the report.
