The United States Postal Service (USPS) has the world's largest civilian fleet, with many of its delivery vehicles reaching the end of their expected 24-year operational lives. USPS is subject to legislative requirements governing the federal fleet, including a requirement in the Energy Policy Act of 1992, which provides that 75 percent of USPS's vehicle acquisitions be alternative fuel vehicles, capable of operating on a fuel other than gasoline. USPS is also facing serious cost pressures in maintaining a national network of processing and retail operations. Asked to review USPS's delivery fleet, GAO (1) profiled the fleet; (2) assessed USPS's response to alternative fuel vehicle requirements and described its experiences with these vehicles; (3) identified USPS's approach for addressing its delivery fleet needs, including trade-offs; and (4) determined options to fund a major acquisition of delivery vehicles. GAO analyzed USPS data; visited USPS facilities in three locations; and interviewed officials from USPS, the Department of Energy, and other organizations, including fleet operators and manufacturers.

USPS's delivery fleet is largely composed of custom-built, right-hand-drive vehicles designed to last for 24 years, including about 141,000 gasoline-powered vehicles 16 to 23 years old and 21,000 flex-fuel vehicles capable of running on gasoline or 85-percent ethanol (E85) that are about 10 years old. The fleet also includes 22,000 left-hand-drive minivans, many of which are also capable of running on E85, and 3,490 delivery vehicles capable of running on other alternative fuels. Delivery vehicles are driven an average of about 17 miles per day and cost about $1 billion to maintain and fuel in fiscal year 2010. USPS met the 75 percent acquisition requirement for alternative fuel vehicles by purchasing about 40,000 flex-fuel vehicles and minivans that can operate on E85 or gasoline. However, USPS does not always use E85 in these vehicles because E85 is not readily available and can cost more to use due to less fuel efficiency, according to USPS officials. USPS has a variety of limited experiences with other alternative fuel vehicles, such as compressed natural gas and plug-in electric vehicles, most of which have higher life-cycle costs than gasoline vehicles. USPS's approach for addressing its delivery fleet needs is to maintain its current fleet until it determines how to address its longer term needs. USPS has incurred small increases in direct maintenance costs over the last 5 years, which were about $2,600 per vehicle in fiscal year 2010. However, it is increasingly incurring costs for unscheduled maintenance because of breakdowns, which can disrupt operations and increase costs. In fiscal year 2010, at least 31 percent of USPS's vehicle maintenance costs were for unscheduled maintenance, 11 percentage points over USPS's 20 percent goal. USPS's financial challenges pose a significant barrier to a major delivery vehicle replacement or refurbishment, estimated to cost $5.8 billion and (in 2005) $3.5 billion, respectively. USPS and other federal and nonfederal officials see little potential to finance a fleet replacement through grants or partnerships. GAO has reported that Congress and USPS need to reach agreement on a package of actions to move USPS toward financial viability. Depending on the specific actions adopted, USPS's follow-up, and the results, such an agreement could enhance its ability to invest in new delivery vehicles. USPS should develop a strategy for addressing its delivery fleet needs that considers the effects of likely operational changes, legislative fleet requirements, and other factors. USPS agreed with GAO's recommendation.

    Recommendation for Executive Action

    Recommendation: Given USPS's need to ensure that its delivery fleet remains operationally viable and maintain its legal mandate to purchase alternative fuel vehicles and use alternative fuel in them, the Postmaster General should develop a strategy and timeline for addressing USPS's delivery fleet needs. This effort should address: (1) the effects of USPS's planned operational changes and continuing changes in customers' use of the mail on future delivery fleet requirements; (2) the range of strategic options available (including continuing to maintain, not replace, its fleet), as well as the costs and time frames for these options; (3) an analysis of any safety consequences associated with extending the vehicles' operational lives; and (4) alternative ways to comply with federal fleet requirements, including an analysis of how USPS can best meet these requirements, given its budget constraints.

    Agency Affected: United States Postal Service

    Status: Open

    Comments: USPS has not been able to purchase new minivans to replace its vehicles with the highest maintenance costs, as it had planned, due to budget constraints over the past few years. USPS is currently aiming for a major purchase in 2017 and is working to develop a plan for that purchase by 2015. To do so, USPS has been assessing its projected needs based on changes in mail volume and the mix of types of mail and conducting market research on vehicle types that could meet its needs. USPS has also been researching alternative fuel vehicle designs and their potential use.
