Radioactive Sources: Opportunities Exist for Federal Agencies to Strengthen Transportation Security
GAO-17-58: Published: Feb 7, 2017. Publicly Released: Mar 9, 2017.
Since September 11, 2001, the three federal agencies responsible for securing risk-significant radioactive sources (those considered most dangerous) during ground transport have taken steps to strengthen the security of these sources. The Nuclear Regulatory Commission (NRC) requires source licensees to ensure that motor carriers transporting these sources have security measures, such as 24-hour mo...
Hazardous Materials Rail Shipments: A Review of Emergency Response Information in Selected Train Documents
GAO-17-130: Published: Dec 2, 2016. Publicly Released: Dec 2, 2016.
To help emergency responders safely handle rail accidents involving hazardous materials, selected railroads transporting hazardous materials typically carry two sources of information: the Department of Transportation's (DOT) Emergency Response Guidebook ( ERG ) and information in the trains' documents. Federal Hazardous Material Regulations require railroads and other hazardous material transpo...
Commercial Space: FAA Should Examine How to Appropriately Regulate Space Support Vehicles
GAO-17-100: Published: Nov 25, 2016. Publicly Released: Nov 25, 2016.
Company officials GAO interviewed identified potential uses for “space support vehicles”—which include a variety of aircraft from high-performance jets to balloons and the aircraft portion of a hybrid launch systems (a vehicle that contains elements of both an aircraft and a rocket-powered launch vehicle)—but the size of the market for these uses is unclear. Company officials said they pla...
Hazardous Materials Rail Shipments: Emergency Responders Receive Support, but DOT Could Improve Oversight of Information Sharing
GAO-17-91: Published: Nov 17, 2016. Publicly Released: Nov 17, 2016.
Emergency planners from most of the 25 selected counties in 17 states that GAO surveyed reported that training for responders and information about rail shipments of hazardous materials affect preparedness. Emergency planners from almost all of the selected counties reported that a majority of the emergency response personnel, such as fire fighters, who arrive first at an accident receive basic tr...
Independent Auditor's Report on Applying Agreed-Upon Procedures: Fiscal Year 2016 Excise Tax Distributions to the Airport and Airway Trust Fund and the Highway Trust Fund
GAO-17-157R: Published: Nov 9, 2016. Publicly Released: Nov 9, 2016.
GAO performed the procedures contained in the enclosures to this report, which it agreed to perform solely to assist the Department of Transportation’s Inspector General in ascertaining whether the net excise tax revenue distributed to the Airport and Airway Trust Fund (AATF) and the Highway Trust Fund (HTF) for the fiscal year ended September 30, 2016, is supported by underlying records. The en...
West Coast Ports: Better Supply Chain Information Could Improve DOT's Freight Efforts
GAO-17-23: Published: Oct 31, 2016. Publicly Released: Oct 31, 2016.
Some infrastructure and operations at major West Coast ports are strained in the face of recent changes in global shipping, but port stakeholders are attempting to address these constraints. For example, as the shipping industry deploys larger vessels capable of delivering more cargo, some port terminals lack big enough cranes, or other infrastructure, needed to handle these vessels. All major Wes...
Train Braking: DOT's Rulemaking on Electronically Controlled Pneumatic Brakes Could Benefit from Additional Data and Transparency
GAO-17-122: Published: Oct 12, 2016. Publicly Released: Oct 12, 2016.
DOT based estimates of the business benefits of electronically controlled pneumatic (ECP) brakes on limited data, in part, because railroads that have used ECP brakes to date have shared limited data on their use. ECP brakes provide an electronic brake signal instantaneously throughout the train, allowing train cars to brake faster than with conventional air brakes. In supporting the May 2015 rule...
Highway Bridges: Linking Funding to Conditions May Help Demonstrate Impact of Federal Investment
GAO-16-779: Published: Sep 14, 2016. Publicly Released: Sep 14, 2016.
Bridge conditions have generally improved nationwide from 2006 to 2015, based on GAO analysis of federal bridge data. For example, the percentage of structurally deficient bridge deck area (the surface area that carries vehicles) decreased from 9 percent to 7 percent nationwide during this period. The number of structurally deficient bridges also decreased from 13 percent to 10 percent nationwide...
Federal Real Property: Public-Private Partnerships Have a Limited Role in Disposal and Management of Unneeded Property
GAO-16-776R: Published: Aug 30, 2016. Publicly Released: Aug 30, 2016.
Federal and state agencies have used public-private partnerships to dispose of unneeded property to a limited extent. General Services Administration (GSA) officials stated that public-private partnerships are explored on a case-by-case basis along with other options for disposing of a federal property and that partnerships are considered for fewer than 10 cases each year. While partnerships can t...
Hazardous Materials Transportation: Better Guidance and Planning Could Enhance DOT's Explosives Classification Oversight
GAO-16-715: Published: Jul 28, 2016. Publicly Released: Jul 28, 2016.
The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration's (PHMSA) oversight of the labs that issue classification recommendations for new explosives is limited by a lack of guidance, and stakeholders have mixed views on PHMSA's oversight. To receive a classification for a new explosive, manufacturers must have an approved test lab examine the explosive and s...
