Why GAO Did this Study

The federal government has increasingly focused on linking affordable housing to transit oriented developments—compact, walkable, mixed-use neighborhoods located near transit—through the Department of Housing and Urban Development’s (HUD) housing programs and the Department of Transportation’s (DOT) Federal Transit Administration’s (FTA) transit programs. GAO was asked to review (1) what is known about how transit-oriented developments affect the availability of affordable housing; (2) how local, state, and federal agencies have worked to ensure that affordable housing is available in transit-oriented developments; and (3) the extent to which HUD and FTA have worked together to ensure that transportation and affordable housing objectives are integrated in transit-oriented developments. To address these issues, GAO reviewed relevant literature, conducted site visits, and interviewed agency officials.

What GAO Found

Characteristics of transit-oriented developments can increase nearby land and housing values, however determining transit-oriented development’s effects on the availability of affordable housing in these developments are complicated by a lack of direct research and data. Specifically, the presence of transit stations, retail, and other desirable amenities such as schools and parks generally increases land and housing values nearby. However, the extent to which land and housing values increase—or in the rare case, decrease—near a transit station depends on a number of characteristics, some of which are commonly found in transit-oriented developments. According to transit and housing stakeholders GAO spoke with, higher land and housing values have the potential to limit the availability of affordable housing near transit, but other factors—such as transit routing decisions and local commitment to affordable housing—can also affect availability.

Few local, state, and federal programs are targeted to assisting local housing and transit providers develop affordable housing in transit-oriented developments. The few targeted programs that exist primarily focus on financial incentives that state and local agencies provide to developers if affordable housing is included in residential developments in transit-oriented developments. However, GAO found that housing developers who develop affordable housing in transit-oriented developments generally rely on local and state programs and policies that have incentives for developing affordable housing in any location. HUD and FTA programs allow local and state agencies to promote affordable housing near transit, but rarely provide direct incentives to target affordable housing in transit-oriented developments.

Since 2005, HUD and FTA, and more recently DOT, have collaborated on three interagency efforts to promote affordable housing in transit-oriented developments including (1) an interagency agreement, (2) a HUD-FTA action plan, and (3) a new DOT-HUD partnership. While these interagency efforts have produced numerous strategies, local housing and transit officials told GAO that these strategies had little impact, in part, because they have yet to be implemented. However, the agencies have not yet developed a comprehensive, integrated plan to implement all efforts, and without such a plan, the agencies risk losing momentum. GAO has previously identified key practices that could enhance and sustain collaboration among federal agencies; when compared to these practices, GAO found that HUD, FTA, and DOT have taken some actions consistent with some of these practices—such as defining a common outcome. However, weaknesses in agency housing data and analytical transportation planning methods will limit these agencies’ ability to effectively monitor, evaluate, and report results—another key collaboration practice. GAO found that other collaboration practices, such as establishing compatible policies and procedures, could be taken to strengthen collaboration. Finally, without a more formalized approach to collaboration, including establishment of memorandum of agreements, these agencies may not effectively leverage their unique strengths.

What GAO Recommends

GAO is recommending that DOT and HUD develop a plan for implementing interagency efforts to promote affordable housing in transit-oriented developments, ensure they collect sufficient data to assess the results of these efforts, and formalize key collaboration practices. DOT and HUD agreed to consider the report’s recommendations.

Why GAO Did This Study

The New Starts program is an important source of new capital investment in mass transportation. To be eligible for federal funding, a project must advance through the different project development phases of the New Starts program, including alternatives analysis, preliminary engineering, and final design. The Federal Transit Administration (FTA) evaluates projects as a condition for advancement into each project development phase of the program. FTA has acted recently to streamline the process. This report discusses:

1. The time it has generally taken for projects to move through the New Starts process and what Congress and FTA have done to expedite the process and
2. Options that exist to expedite the process.

In response to a legislative mandate, GAO reviewed statutes, FTA guidance and regulations, and project data. GAO also interviewed Department of Transportation (DOT) officials, projects sponsors, and industry stakeholders.

What GAO Recommends

GAO recommends that DOT consider options to expedite project development and continue to improve its data collection efforts. DOT agreed with the first recommendation but not the second, which GAO revised to better reflect FTA’s efforts to date and the ongoing need for complete and reliable data to help strengthen the program.

What GAO Found

Insufficient data are available to describe the time it has taken for all projects to move through the New Starts process. Nevertheless, 9 of 40 projects that have received full funding grant agreements since 1997, and had complete data available, had milestone dates that ranged from about 4 to 14 years to complete the project development phases. However, the data from these 9 projects are not generalizeable to the 40 New Starts projects.

FTA has not historically retained all milestone data for every project, such as the dates that project sponsors apply to enter preliminary engineering and FTA’s subsequent approval. Although not required by its records retention policy, FTA has retained milestone data from some projects longer than 2 years. However, GAO was unable to obtain complete and reliable project milestone data from FTA.

FTA officials acknowledged that, while not historically perfect, the agency has retained sufficient milestone data to help manage the New Starts program. Nevertheless, recognizing the importance of having complete milestone data, FTA has taken several steps in recent years to more consistently collect and retain such data. In addition, GAO found that project sponsors do not consistently retain milestone data for projects that have completed the New Starts process.

Congress and FTA have taken action to expedite projects through the New Starts process. For example, legislative action created the Public-Private Partnership Pilot Program (Penta-P) to study the benefits of using public-private partnerships for certain new fixed-guideway capital projects, such as accelerating project delivery. In addition, FTA has implemented administrative changes to expedite the New Starts process. For example, FTA has developed and offered training workshops for project sponsors and has introduced project delivery tools. These tools include checklists for project sponsors to improve their understanding of the requirements of each phase of the New Starts process.

Project sponsors and industry stakeholders GAO interviewed identified options to help expedite project development within the New Starts program. These options include tailoring the New Starts evaluation process to risks posed by the projects, using letters of intent more frequently, and applying policy and guidance changes only to future projects. Each option has advantages and disadvantages to consider.

In addition, FTA must also strike the appropriate balance between expediting project delivery and maintaining the accountability of the program. For example, by signaling early federal support of projects, letters of intent could help project sponsors use potentially less costly and time-consuming alternative project delivery methods, such as design-build. However, such early support poses some risk.

It is possible that with more frequent use of letters of intent, FTA’s commitment authority could be depleted earlier than expected, which could affect the anticipated funding stream for future projects. Furthermore, some options, like combining one or more statutorily required project development phases, would require legislative action.

Why GAO Did this Study

In 1995, the Department of Defense (DOD) began an effort to implement a standard departmentwide travel system—the Defense Travel System (DTS). GAO has made numerous recommendations aimed at improving DOD management, oversight, and implementation of DTS.

GAO was asked to:

• Assess the actions DOD has taken to implement GAO’s prior recommendations;
• Determine the actions DOD has taken to standardize and streamline its travel rules and processes;
• Determine if DOD has identified its legacy travel systems, their operating costs, and which of these systems will be eliminated; and
• Report on DOD’s costs to process travel vouchers manually and electronically.

To address these objectives, GAO (1) obtained and analyzed relevant travel policies and procedures, and documents related to the operation of DTS and (2) interviewed appropriate DOD and contractor personnel.

What GAO Found

While the department has made progress in improving the efficiency of its travel operations by implementing DTS and revising its processes and policies, unresolved operational issues continue to exist. DOD has taken sufficient action to satisfactorily address 6 of the 14 recommendations GAO made in 2006 pertaining to unused airline tickets, restricted airfares, testing of system interfaces, and streamlining of certain travel processes. More effort is needed to address the remaining 8 related to requirements management and system testing, utilization, premium-class travel, and developing an automated approach to reduce the need for hard-copy receipts to substantiate travel expenses. For example, in the area of requirements management and testing, GAO’s analysis found that the display of flight information by DTS is complicated and confusing. This problem continues because DOD has yet to establish DTS flight display requirements that minimize the number of screens DOD travelers must view in selecting a flight.

The 1995 DOD Travel Reengineering Report made 22 recommendations to streamline DOD’s travel rules and processes. GAO found that DOD had satisfactorily addressed all 22 recommendations. For example, DOD has mandated the use of commercial travel offices (CTO), established a single entity within DOD—the Defense Travel Management Office—to contract with CTOs for travel services, and has begun modifying CTO contracts as they become subject to renewal to standardize the level of services provided.

According to DOD officials, except for locations where DTS has not yet been deployed, DTS is used by the military services and all 44 defense agencies and joint commands to process temporary duty (TDY) travel vouchers. The department uses two legacy systems to process:

• TDY travel vouchers at locations where DTS is not yet deployed and
• Civilian and military permanent duty travel vouchers since DTS currently lacks the functionality to process these vouchers.

DOD provided us with fiscal year 2008 expenditure data for one system and budget data for the other system. The expenditure/budget data provided by DOD were comparable to the amounts budgeted for these systems for fiscal year 2008. According to DOD officials, these legacy systems will not be eliminated because they provide the capability to process military and civilian permanent duty travel vouchers. Although DTS is expected to provide the capability to process military permanent duty travel vouchers in fiscal year 2010, DOD has not yet decided if civilian permanent duty travel voucher processing will be added to DTS.

DOD cost data indicate that it is about 15 times more expensive to process a travel voucher manually—$36.52 manually versus $2.47 electronically. DOD officials acknowledged that the department continues to lack the data needed to ascertain the complete universe of travel vouchers that should be processed through DTS.

What GAO Recommends

Because GAO has existing recommendations regarding the actions needed to address the weaknesses discussed in this report, GAO reiterates 8 of its 14 prior recommendations. DOD commented that it has taken sufficient action to address 12 of the 14 recommendations, including 6 of the 8 GAO is reiterating, and described actions under way or planned to address the other 2. GAO disagrees. GAO received technical comments, which were incorporated as appropriate.

Background

In 2008, GAO reported that 1,088 oil industry mergers occurred between 2000 and 2007. Given the potential for price effects, GAO recommended that the Federal Trade Commission (FTC), the agency with the authority to maintain petroleum industry competition, undertake more regular retrospective reviews of past petroleum industry mergers, and FTC said it would consider this recommendation. GAO was asked to conduct such a review of its own to determine how mergers and market concentration—a measure of the number and market shares of firms in a market—affected wholesale gasoline prices since 2000.

GAO examined the effects of mergers and market concentration using an economic model that ruled out the effects of many other factors. GAO consulted with a number of experts and used both public and private data in developing the model. GAO tested the model under a variety of assumptions to address some of its limitations. GAO also interviewed petroleum market participants.

Study Findings

Image Courtesy: GAO

GAO examined seven mergers that occurred since 2000—ranging in value and geography and for which there was available gasoline pricing data (see table)—and found three that were associated with statistically significant increases or decreases in wholesale gasoline prices. Specifically, GAO found that the mergers of Valero Energy with Ultramar Diamond Shamrock and Valero Energy with Premcor, which both involved the acquisition of refineries, were associated with estimated average price increases of about 1 cent per gallon each. In addition, GAO found that the merger of Phillips Petroleum with Conoco, which primarily involved the acquisition of oil exploration and production assets, was associated with an estimated average decrease in wholesale gasoline prices across cities affected by the merger of nearly 2 cents per gallon. This analysis provides an indicator of the impact that petroleum industry mergers can have on wholesale gasoline prices. Additional analysis would be needed to explain the price effects that GAO estimated.

GAO used two separate measures of market concentration, one which measured the number of sellers at wholesale gasoline terminals and another which measured the market share of refiners supplying gasoline to those sellers, and found that less concentrated markets were statistically significantly associated with lower gasoline prices. For example, for wholesale terminals with more sellers—i.e., terminals that were less concentrated—GAO estimated that prices were about 8 cents per gallon lower at terminals with 14 sellers than at terminals that had only 9 sellers. This result is consistent with the idea that markets with more sellers are likely to be more competitive, resulting in lower prices. Using the second measure of concentration, GAO similarly found a statistically significant association between prices and the level of refinery concentration, with less concentrated groups of refineries associated with lower prices.

GAO Recommendation

This study reinforces the need to review past petroleum industry mergers, and GAO continues to recommend that FTC conduct such reviews more regularly and develop risk-based guidelines to determine when to conduct them. FTC reviewed a draft of this report and supports GAO’s recommendation to conduct more reviews of past petroleum industry mergers.

Aircraft emit greenhouse gases and other emissions, contributing to increasing concentrations of such gases in the atmosphere. Many scientists and the Intergovernmental Panel on Climate Change (IPCC)–a United Nations organization that assesses scientific, technical, and economic information on climate change–believe these gases may negatively affect the earth’s climate. Given forecasts of growth in aviation emissions, some governments are taking steps to reduce emissions.

In response to a congressional request, GAO reviewed:

(1) estimates of aviation’s current and future contribution to greenhouse gas and other emissions that may affect climate change;

(2) existing and potential technological and operational improvements that can reduce aircraft emissions; and

(3) policy options for governments to help address commercial aircraft emissions.

GAO conducted a literature review; interviewed representatives of government agencies, industry and environmental organizations, airlines, and manufacturers, and interviewed and surveyed 18 experts in economics and aviation on improvements for reducing emissions from aircraft. GAO is not making recommendations. Relevant agencies provided technical comments which we incorporated as appropriate and EPA said emissions standards can have a positive benefit to cost ratio and be an important part of policy options to control emissions.

According to IPCC, aviation currently accounts for about 2 percent of human-generated global carbon dioxide emissions, the most significant greenhouse gas–and about 3 percent of the potential warming effect of global emissions that can affect the earth’s climate, including carbon dioxide. IPCC’s medium-range estimate forecasts that by 2050 the global aviation industry, including aircraft emissions, will emit about 3 percent of global carbon dioxide emissions and about 5 percent of the potential warming effect of all global human-generated emissions. Gross domestic product growth is the primary driver in IPCC’s forecasts. IPCC also made other assumptions about future aircraft fuel efficiency, improvements in air traffic management, and airport and runway capacity. IPCC’s 2050 forecasts for aviation’s contribution to global emissions assumed that emissions from other sectors will continue to grow.

If other sectors make progress in reducing emissions and aviation emissions continue to grow, aviation’s relative contribution may be greater than IPCC estimated; on the other hand, if other sectors do not make progress, aviation’s relative contribution may be smaller than estimated. While airlines currently rely on a range of improvements, such as fuel-efficient engines, to reduce emissions, some of which may have limited potential to generate future reductions, experts we surveyed expect a number of additional technological, operational, and alternative fuel improvements to help reduce aircraft emissions in the future. However, according to experts we interviewed, some technologies, such as advanced airframes, have potential, but may be years away from being available, and developing and adopting them is likely to be costly.

In addition, according to some experts we interviewed, incentives for industry to research and adopt low-emissions technologies will be dependent to some extent on the level and stability of fuel prices. Finally, given expected growth of commercial aviation as forecasted by IPCC, even if many of these improvements are adopted, it appears unlikely they would greatly reduce emissions by 2050. A number of policy options to address aircraft emissions are available to governments and can be part of broader policies to address emissions from many sources including aircraft. Market-based measures can establish a price for emissions and provide incentives to airlines and consumers to reduce emissions. These measures can be preferable to other options because they would generally be more economically efficient. Such measures include a cap-and-trade program, in which government places a limit on emissions from regulated sources, provides them with allowances for emissions, and establishes a market for them to trade emissions allowances with one another, and a tax on emissions. Governments can establish emissions standards for aircraft or engines. In addition, government could increase government research and development to encourage development of low-emissions improvements.

The U.S. transportation sector relies almost exclusively on oil; as a result, it causes about a third of the nation’s greenhouse gas emissions. Advanced technology vehicles powered by alternative fuels, such as electricity and ethanol, are one way to reduce oil consumption. The federal government set a goal for federal agencies to use plug-in hybrid electric vehicles–vehicles that run on both gasoline and batteries charged by connecting a plug into an electric power source–as they become available at a reasonable cost. This goal is on top of other requirements agencies must meet for conserving energy.

In response to a request, GAO examined the:

(1) potential benefits of plug-ins,

(2) factors affecting the availability of plug-ins, and

(3) challenges to incorporating plug-ins into the federal fleet. GAO reviewed literature on plug-ins, federal legislation, and agency policies and interviewed federal officials, experts, and industry stakeholders, including auto and battery manufacturers.

Increasing the use of plug-ins could result in environmental and other benefits, but realizing these benefits depends on several factors. Because plug-ins are powered at least in part by electricity, they could significantly reduce oil consumption and associated greenhouse gas emissions. For plug-ins to realize their full potential, electricity would need to be generated from lower-emission fuels such as nuclear and renewable energy rather than the fossil fuels–coal and natural gas–used most often to generate electricity today. However, new nuclear plants and renewable energy sources can be controversial and expensive. In addition, research suggests that for plug-ins to be cost-effective relative to gasoline vehicles the price of batteries must come down significantly and gasoline prices must be high relative to electricity.

Auto manufacturers plan to introduce a range of plug-in models over the next 6 years, but several factors could delay widespread availability and affect the extent to which consumers are willing to purchase plug-ins. For example, limited battery manufacturing, relatively low gasoline prices, and declining vehicle sales could delay availability and discourage consumers. Other factors may emerge over the longer term if the use of plug-ins increases, including managing the impact on the electrical grid (the network linking the generation, transmission, and distribution of electricity) and increasing consumer access to public charging infrastructure needed to charge the vehicles.

The federal government has supported plug-in-related research and initiated new programs to encourage manufacturing. Experts also identified options for providing additional federal support. To incorporate plug-ins into the federal fleet, agencies will face challenges related to cost, availability, planning, and federal requirements. Plug-ins are expected to have high upfront costs when they are first introduced. However, they could become comparable to gasoline vehicles over the life of ownership if certain factors change, such as a decrease in the cost of batteries and an increase in gasoline prices.

Agencies vary in the extent to which they use life-cycle costing when evaluating which vehicle to purchase. Agencies also may find that plug-ins are not available to them, especially when the vehicles are initially introduced because the number available to the government may be limited. In addition, agencies have not made plans to incorporate plug-ins due to uncertainties about vehicle cost, performance, and infrastructure needs.

Finally, agencies must meet a number of requirements covering energy use and vehicle acquisition–such as acquiring alternative fuel vehicles and reducing facility energy and petroleum consumption–but these sometimes conflict with one another. For example, plugging vehicles into federal facilities could reduce petroleum consumption but increase facility energy use. The federal government has not yet provided information to agencies on how to set priorities for these requirements or leverage different types of vehicles to do so. Without such information, agencies face challenges in making decisions about acquiring plug-ins that will meet the requirements, as well as maximize plug-ins’ potential benefits and minimize costs.

The recommendations are listed below:

• To enable agencies to more effectively meet congressional requirements, the Secretary of Energy should, in consultation with Environmental Protection Agency (EPA), General Services Administration (GSA), Office of Management and Budget (OMB), and organizations representing federal fleet customers such as Interagency Committee for Alternative Fuels and Low-Emission Vehicles (INTERFUEL), Federal Fleet Policy Council (FEDFLEET), and the Motor Vehicle Executive Council, propose legislative changes that would resolve the conflicts and set priorities for the multiple requirements and goals with respect to reducing petroleum consumption, reducing emissions, managing costs, and acquiring advanced technology vehicles.
• The Secretary of Energy should begin to develop guidance for when agencies consider acquiring plug-in vehicles, as well as guidance specifying the elements that agencies should include in their plans for acquiring the mix of vehicles that will best enable them to meet their requirements and goals. Such guidance might include assessing the need for installing charging infrastructure and identifying areas where improvements may be necessary, mapping current driving patterns, and determining the energy sources used to generate electricity in an area.
• The Secretary of Energy should continue ongoing efforts to develop guidance for agencies on how electricity used to charge plug-ins should be measured and accounted for in meeting energy-reduction goals related to federal facilities and alternative fuel consumption. In doing so, the Secretary should determine whether changes to existing legislation will be needed to ensure there is no conflict between using electricity to charge vehicles and requirements to reduce the energy intensity of federal facilities, and advise Congress accordingly.
• The Administrator of GSA should consider providing information to agencies regarding total cost of ownership or life-cycle cost for vehicles in the same class. For plug-in vehicles that are newly offered, the Administrator should provide guidance for how agencies should address uncertainties about the vehicles’ future performance in estimating the life-cycle costs of plug-ins, so agencies can make better-informed, consistent, and cost-effective decisions in acquiring vehicles.
• Once plug-in hybrids and all-electrics become available to the federal government but are still in the early phases of commercialization, the Administrator of GSA should explore the possibility of arranging pass-through leases of plug-in vehicles directly from vehicle manufacturers or dealers–as is being done with DOD’s acquisition of neighborhood electric vehicles–if doing so proves to be a cost-effective means of reducing some of the risk agencies face associated with acquiring new technology.
