On June 22, 2009, two transit trains in Washington, DC, collided, resulting in nine deaths and dozens of injuries. It was the worst crash in the history of the Washington Metropolitan Area Transit Authority's rail transit system. This crash has raised questions about the safety of rail transit and the government's role in ensuring that safety. Nationwide, rail transit is considered one of the safest modes of transportation. This report discusses the State Safety Oversight Program, which went into effect in 1997 and mandates that states are responsible for the safety of the rail transit systems within their borders. This report also explores several issues that Federal Transit Administration (FTA) representatives have discussed in regards to improving the Safety Oversight Program.

This report discusses the economic impacts of existing activities and gives a preliminary feasibility assessment for new fairgrounds and expo center. The economic and fiscal impacts generated by fairs, rodeos, horse shows, and cattle shows nationwide are significant. Impacts estimated in the millions of dollars are not uncommon for regional and state events. It is against this backdrop that the University of North Texas Center for Economic Development and Research has been asked to estimate the economic and fiscal impacts of the North Texas State Fair & Rodeo, as well as examine the potential market for and economic and fiscal impacts of building a new exposition center in Denton County. Later in this report, we will also examine the experiences of ten exposition centers across Texas and the U.S. that illustrate the types of events, and the associated costs, that would likely attend construction and operation of such a center in Denton County.

This report provides an overview of Lebanese politics, recent events in Lebanon, and current issues in U.S.-Lebanon relations and will be updated to reflect major developments.

With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the ongoing process whereby seawater becomes acidified (i.e., ocean acidification) as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase.

This report begins with a look at the motivating factors underlying the resurgent interest in nuclear power, the nuclear power industry's current state of affairs, and the interdependence of the various stages of the nuclear fuel cycle. A number of proposals have been offered that are aimed at limiting direct participation in the global nuclear fuel industry by assuring access to nuclear fuel supplies.

This report offers an introduction and overview of legislation regarding greenhouse gases. It also discusses combined efficiency and renewable electricity standard, geologic sequestration of carbon dioxide, vehicles and fuels, smart grid, energy efficiency, and major cap-and-trade provisions.

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Justice (DOJ) estimates that the United States has about a million gang members. While state and local agencies have primary responsibility for combating gang crime, the federal government has key roles to enforce laws and help fund programs to provide alternatives to gang membership for at-risk youth. GAO was asked to examine federal efforts to combat gang crime. This report addresses (1) the roles of DOJ and the Department of Homeland Security (DHS) in combating gang crime and the extent to which DOJ and DHS agencies coordinate their efforts with each other and state and local agencies; (2) the extent to which DOJ and DHS measure their gang enforcement efforts; and (3) how federal grant funding is used to administer or support activities to reduce gang-related crime. GAO reviewed federal agencies' plans, resources, and measures and interviewed federal, state, and local officials in 15 localities with federally led anti-gang task forces representing varying population sizes and locations."

A letter report issued by the Government Accountability Office with an abstract that begins "From fiscal years 2000 through 2008, the number of persons employed by federal agencies who perform various law enforcement functions and receive either special pay or enhanced retirement benefits, in the form of a faster-accruing pension, has increased by 55 percent. In addition, as of September 2008, approximately 51,000 personnel were employed in law enforcement-related occupations that could seek enhanced retirement benefits in the future. GAO was asked to conduct a review of the retirement benefits provided to law enforcement personnel. This report addresses (1) the processes used to grant enhanced retirement benefits to federal law enforcement personnel, (2) the rationales and potential costs for extending benefits to additional occupations, and (3) the extent to which federal agencies used human capital tools to retain law enforcement and other related personnel. GAO reviewed relevant laws, regulations, and other documentation, such as agency reports describing the processes used to grant enhanced benefits, and interviewed officials from the Office of Personnel Management (OPM), Department of Homeland Security (DHS), Department of Justice (DOJ), and the Internal Revenue Service (IRS) because these entities employed approximately 84 percent of all law enforcement …

A letter report issued by the Government Accountability Office with an abstract that begins "Biosafety laboratories are primarily regulated by either the Department of Health and Human Services (HHS) or the U.S. Department of Agriculture (USDA), depending on whether the substances they handle pose a threat to the health of humans or plants, animals, and related products, respectively. Currently, all operational biosafety level 4 (BSL-4) labs are overseen by HHS's Centers for Disease Control and Prevention (CDC). BSL-4 labs handle the world's most dangerous agents and toxins that cause incurable and deadly diseases. In September 2008, GAO reported that two of the five operational BSL-4 labs had less than a third of the key perimeter security controls GAO assessed and recommended that CDC implement specific perimeter controls for all BSL-4 labs. GAO was asked to (1) provide an update on what action, if any, CDC took to address the 2008 recommendation; (2) determine whether perimeter security controls at the two deficient BSL-4 labs had improved since the 2008 report; and (3) provide other observations about the BSL-4 labs it assessed. To meet these objectives, GAO reviewed CDC's statement to Congress as well as other agency and HHS documentation on actions …

A letter report issued by the Government Accountability Office with an abstract that begins "Foot-and-mouth disease (FMD) is the most highly infectious animal disease known: nearly 100 percent of exposed animals become infected with it. Although the United States has not had an outbreak of FMD since 1929, a single outbreak of FMD virus as a result of an accidental or intentional release from a laboratory on the U.S. mainland could have significant consequences for U.S. agriculture. The traditional approach to the disease, once infection is confirmed, is to depopulate infected and potentially infected livestock herds to eradicate the disease. The value of U.S. livestock sales was $140 billion in 2007; about 10 percent of this figure, or approximately $13 billion, was accounted for by export markets. The Plum Island Animal Disease Center (PIADC), on a federally owned island off the northern tip of Long Island, New York, is the only facility in the United States that studies the live FMD virus. The U.S. Department of Agriculture (USDA) was responsible for the PIADC from its opening in the 1950s until June 2003, when USDA transferred responsibility for it to the U.S. Department of Homeland Security (DHS), as required by the …

A letter report issued by the Government Accountability Office with an abstract that begins "After the Small Business Administration (SBA) was widely criticized for its performance following the 2005 Gulf Coast hurricanes, the agency took steps to reform the Disaster Loan Program and Congress enacted the Small Business Disaster Response and Loan Improvements Act of 2008 (Act). GAO was asked to determine (1) the extent to which SBA addressed the Act's requirements, and (2) how SBA's response to major disasters in 2008 aligned with key components of its June 2007 Disaster Recovery Plan (DRP). GAO reviewed the Act, as well as SBA information on requirements addressed and steps taken, including the DRP, various reports to Congress, and policy memoranda. GAO also conducted site visits to areas affected by major 2008 disasters, reviewed SBA's customer satisfaction survey, and obtained the opinions of relevant stakeholders."

A letter report issued by the Government Accountability Office with an abstract that begins "As part of its more than $24 billion Deepwater program to replace aging vessels and aircraft with new or upgraded assets, the Coast Guard is preparing the National Security Cutter (NSC) for service. GAO previously reported on Deepwater assets' deployment delays and the Coast Guard's management of the Deepwater program. GAO was legislatively directed to continue its oversight of the Deepwater program. As a result, this report addresses: (1) the operational effects, if any, of delays in the delivery of the NSC and its support assets of unmanned aircraft and small boats; (2) Coast Guard plans for mitigating any operational effects and any associated costs of these plans; and (3) the extent to which the Coast Guard has plans, to include cost estimates, for phasing in logistics support of the NSC while phasing out support for the High Endurance Cutter (HEC) it is replacing. GAO's work is based on analyses of the (1) operational capabilities and maintenance plans of the NSC and its support assets and (2) data on the HECs' condition; comparison of an NSC and HEC; and, interviews with Coast Guard officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Emergency Economic Stabilization Act directed GAO to study the role of leverage in the current financial crisis and federal oversight of leverage. GAO's objectives were to review (1) how leveraging and deleveraging by financial institutions may have contributed to the crisis, (2) regulations adopted by federal financial regulators to limit leverage and how regulators oversee compliance with the regulations, and (3) any limitations the current crisis has revealed in regulatory approaches used to restrict leverage and regulatory proposals to address them. To meet these objectives, GAO built on its existing body of work, reviewed relevant laws and regulations and academic and other studies, and interviewed regulators and market participants."

A letter report issued by the Government Accountability Office with an abstract that begins "The Deepwater Program includes efforts to build or modernize ships and aircraft and to procure other capabilities. In 2002, the Coast Guard contracted with Integrated Coast Guard Systems (ICGS) to manage the acquisition as systems integrator. After a series of project failures, the Coast Guard announced in April 2007 that it would take over the lead role, with future work on individual assets bid competitively, and a program baseline of $24.2 billion was set. In June 2008, GAO reported on the Coast Guard's progress and made several recommendations, which the Coast Guard and the Department of Homeland Security (DHS) have addressed. In response to a Senate report accompanying the DHS Appropriations Bill, 2009, GAO addressed (1) efforts to manage Deepwater, (2) changes in cost and schedule of the assets, and (3) efforts to build an acquisition workforce. GAO reviewed Coast Guard and DHS documents and interviewed officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2008, about 31 million children participated in the National School Lunch Program and more than 10 million children participated in the School Breakfast Program each school day. The U.S. Department of Agriculture's (USDA) Food and Nutrition Service (FNS) spent $11.7 billion on the school meal programs in that year. The majority of school meals are provided for free or at a reduced price to low-income students. Some states and school districts have chosen to implement programs that eliminate the reduced-price fee (known as ERP programs) and instead provide free meals to students eligible for the reduced fee. GAO was asked to provide information on (1) what is known about the states and districts that have eliminated the reduced-price fee for school meals, (2) the experiences of states and districts that have ERP programs with respect to participation, errors, and costs, and (3) the factors that may help or hinder the establishment or continuation of ERP programs. To obtain this information, GAO interviewed FNS officials, interviewed officials from state- and district-level programs, and conducted a Web-based survey of the 35 districts identified as having …

A letter report issued by the Government Accountability Office with an abstract that begins "Currently in Iraq, there are thousands of private security contractor (PSC) personnel supporting DOD and State, many of whom are foreign nationals. Congressional concerns about the selection, training, equipping, and conduct of personnel performing private security functions in Iraq are reflected in a provision in the fiscal year 2008 National Defense Authorization Act (NDAA) that directs DOD to develop guidance on PSCs. This report examines the extent (1) that DOD and State have developed and implemented policies and procedures to ensure that the backgrounds of PSC employees have been screened and (2) that DOD has developed guidance to implement the provisions of the NDAA and (3) that DOD and State have addressed measures on other issues related to PSC employees in Iraq. To address these objectives, GAO reviewed DOD and State guidance, policies, and contract oversight documentation and interviewed agency and private security industry officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2005-2006, students with disabilities comprised 9 percent of the student population in the United States, and English language learners comprised about 10 percent. Many of these students spend a majority of their time in the general classroom setting in elementary and secondary schools. Most teachers are initially trained through teacher preparation programs at institutions of higher education. GAO was asked to examine (1) the extent to which teacher preparation programs require preparation for general classroom teachers to instruct these student subgroups; (2) the role selected states play in preparing general classroom teachers to instruct these student subgroups; and (3) funding and other assistance provided by the U.S. Department of Education (Education) to help general classroom teachers instruct these student subgroups. To address these issues, GAO conducted a nationally representative survey of teacher preparation programs and interviewed officials from state and local educational agencies in four states and Education."

A letter report issued by the Government Accountability Office with an abstract that begins "Reverse mortgages--a type of loan against home equity available to seniors--are growing in popularity. A large majority of reverse mortgages are insured by the Department of Housing and Urban Development (HUD) under its Home Equity Conversion Mortgage (HECM) program. The Housing and Economic Recovery Act of 2008 (HERA) made several modifications to the HECM program, including changes in how origination fees are calculated and an increase in the loan limit. The Act directed GAO to examine (1) how these changes have affected lenders' plans to offer reverse mortgages, (2) how the changes will affect borrowers, and (3) actions HUD has taken to evaluate the financial performance of the HECM program. To address these objectives, GAO surveyed a representative sample of HECM lenders, analyzed loan-level HECM data, and reviewed HUD estimates and analysis of HECM program costs."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Defense Authorization Act for Fiscal Year 2008 required the Department of Defense (DOD) and the Department of Veterans Affairs (VA) to accelerate their exchange of health information and to develop systems or capabilities that allow for interoperability (generally, the ability of systems to exchange data) by September 30, 2009. It also required compliance with federal standards and the establishment of a joint interagency program office to function as a single point of accountability for the effort. Further, the act directed GAO to semiannually report on the progress made in achieving these requirements. For this third report, GAO evaluated (1) the departments' progress and plans toward sharing fully interoperable electronic health information that comply with federal standards and (2) whether the interagency program office is positioned to function as a single point of accountability. To do so, GAO analyzed agency documentation on project status and conducted interviews with agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2008, GAO reported that, with the exception of the period following Hurricanes Katrina and Rita, refinery outages in the United States did not show discernible trends in reduced production capacity, frequency, and location from 2002 through 2007. Some outages are planned to perform routine maintenance or upgrades, while unplanned outages occur as a result of equipment failure or other unforeseen problems. GAO was asked to (1) evaluate the effect of refinery outages on wholesale gasoline prices and (2) identify gaps in federal data needed for this and similar analyses. GAO selected refinery outages from 2002 through September 2008 that were at least among the largest 60 percent in terms of lost production capacity in their market region and lasted at least 3 days. GAO developed an econometric model and tested a variety of assumptions using public and private data."

A letter report issued by the Government Accountability Office with an abstract that begins "H.R. 3915 (2007), a bill introduced, but not enacted by the 110th Congress, was intended to reform mortgage lending practices to prevent a recurrence of problems in the mortgage market, particularly in the nonprime market segment. The bill would have set minimum standards for all mortgages (e.g., reasonable ability to repay) and created a "safe harbor" for loans that met certain requirements. Securitizers of safe harbor loans would be exempt from liability provisions, while securitizers of non-safe harbor loans would be subject to limited liability for loans that violated the bill's minimum standards. In response to a congressional request, this report discusses (1) the proportions of recent nonprime loans that likely would have met and not met the bill's safe harbor requirements and factors influencing the performance of these loans, and (2) relevant research and the views of mortgage industry stakeholders concerning the potential impact of key provisions of the bill on the availability of mortgage credit. To do this work, GAO analyzed a proprietary database of securitized nonprime loans, reviewed studies of state and local anti-predatory lending laws, and met with financial regulatory agencies and …

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Postal Service (USPS) is facing significant financial problems as mail volume is declining, 4.5 percent in fiscal year 2008 and 11 percent projected for fiscal year 2009. USPS lost $2.8 billion in fiscal year 2008 and projects a $6.4 billion loss in fiscal year 2009 (possibly more if it cannot cut an ambitious $5.9 billion in costs). As one way to cut costs, USPS is trying to improve the efficiency of mail delivery, which generates close to one-third of USPS's $78 billion in expenses. Recognizing the sizeable impact of delivery on USPS's finances and operations, you requested a GAO review. This report addresses (1) how USPS monitors delivery efficiency; (2) characteristics of delivery units that affect their efficiency; and (3) the status and results of USPS's actions to improve delivery efficiency, in particular USPS's Flats Sequencing System (FSS). To address these objectives, GAO interviewed stakeholders and USPS officials, reviewed delivery documentation, conducted fieldwork, and analyzed delivery data."
