VA Health Care: Preliminary Findings on the Department of Veterans Affairs Health Care Budget Formulation for Fiscal Years 2005 and 2006

Correspondence issued by the Government Accountability Office with an abstract that begins "This report documents the information we provided to Congress in a briefing on February 2, 2006, in response to a request concerning the Department of Veterans Affairs (VA) internal budget formulation process. This includes information that VA develops for its budget submission to the Office of Management and Budget (OMB), but it does not include information on subsequent interactions that occur between VA and OMB. We will do additional work to incorporate information from OMB and complete our analysis in a report to be issued at a later date. Congress requested information on VA's budget formulation process because of its interest in ensuring that VA's budget forecasts are accurate and based on valid patient estimates. In response to the request for information on VA's internal budget formulation process, this report provides the following for fiscal years 2005 and 2006: (1) a description of VA's process for developing its budget submission to OMB for its medical programs, and the role of VA's actuarial model; (2) a description of the medical program activities cited by VA as needing additional funding, and how VA identified these activities; and (3) key factors …

Surface Transportation: Preliminary Observations on Efforts to Restructure Current Program (open access)

Surface Transportation: Preliminary Observations on Efforts to Restructure Current Program

Testimony issued by the Government Accountability Office with an abstract that begins "The nation has reached a critical juncture with its current surface transportation policies and programs. Demand has outpaced the capacity of the system, resulting in increased congestion. In addition, without significant changes in funding mechanisms, revenue sources, or planned spending, the Highway Trust Fund--the major source of federal highway and transit funding--is projected to incur significant deficits in the years ahead. Furthermore, the nation is on a fiscally unsustainable path. Recognizing many of these challenges and the importance of the transportation system to the nation, Congress established The National Surface Transportation Policy and Revenue Study Commission (Commission) to examine current and future needs of the system and recommend needed changes to the surface transportation program, among other things. The Commission issued its report in January 2008. This testimony discusses 1) principles to assess proposals for restructuring the surface transportation program and 2) GAO's preliminary observations on the Commission's recommendations. This statement is based on GAO's ongoing work for the Ranking Member of this Committee, the Chairman of the House Transportation and Infrastructure Committee, Senator DeMint, as well as a body of work GAO has completed over the past …

Immigration Benefits: Internal Controls for Adjudicating Humanitarian Parole Cases Are Generally Effective, but Some Can Be Strengthened (open access)

Immigration Benefits: Internal Controls for Adjudicating Humanitarian Parole Cases Are Generally Effective, but Some Can Be Strengthened

A letter report issued by the Government Accountability Office with an abstract that begins "The Immigration and Nationality Act requires that most visitors and immigrants to the United States obtain a visa. Aliens unable to obtain a visa, and with a compelling humanitarian need, may apply to the Department of Homeland Security (DHS) to be granted humanitarian parole. This permits an alien to enter the United States on a temporary basis. Parole responsibility rests with DHS's Humanitarian Assistance Branch (HAB), which was transferred to the U.S. Citizenship and Immigration Services (USCIS) in August 2007. In response to congressional requesters, GAO examined (1) the characteristics of those who applied for humanitarian parole since October 1, 2001, and (2) internal controls HAB designed to adjudicate applications along with the extent to which HAB adhered to them. To conduct this work, GAO analyzed HAB documents and data, such as its protocols and database of all parole applications since October 1, 2001; interviewed HAB officials about adjudication processes; and interviewed attorneys who had helped individuals file for parole."

The Department of Defense's Civilian Human Capital Strategic Plan Does Not Meet Most Statutory Requirements (open access)

The Department of Defense's Civilian Human Capital Strategic Plan Does Not Meet Most Statutory Requirements

Correspondence issued by the Government Accountability Office with an abstract that begins "The achievement of the Department of Defense's (DOD) mission is dependent in large part on the skills and expertise of its civilian workforce--which consists of almost 700,000 personnel, who develop policy, provide intelligence, manage finances, and acquire and maintain weapon systems. With more than 50 percent of its civilian personnel becoming eligible to retire in the next few years, DOD may find it difficult to fill certain mission-critical jobs with qualified personnel. Strategic workforce planning, an integral part of human capital management, helps ensure that an organization has staff with the necessary skills and competencies to accomplish its strategic goals. We have previously reported that it is critical that DOD engage in effective strategic workforce planning to ensure that its human capital reforms have maximum effectiveness and value. In 2007, we reported that strategic human capital management remained a high-risk area because the federal government now faces one of the most significant transformations to the civil service in half a century, as momentum grows toward making governmentwide changes to agency pay, classification, and performance management systems. In January 2006, the National Defense Authorization Act for Fiscal Year 20065 …

GSA Global Supply's Direct Vendor Delivery Proposal Addresses Declining Office Product Sales, but Annual Reviews May Be Needed to Monitor Impact on Small Business Participation

Correspondence issued by the Government Accountability Office with an abstract that begins "In fiscal year 2007, the General Services Administration (GSA) purchased $853 million in supplies from businesses--large and small--for its Global Supply system for subsequent resale to federal agencies. Of this amount, $194 million was for office products sold through the Global Supply Stock Program (Stock Program). The Stock Program allows federal customers to purchase thousands of products, ranging from office supplies to firefighting equipment, from two GSA distribution centers. In an effort to reduce delivery times and cut costs, GSA has worked for several years to develop a new business model for the Stock Program. In November 2008, GSA issued a solicitation for proposals that would remove one-third, or about 550, of its office supply products from the Stock Program and require businesses to ship these office products directly to GSA customers. Under the proposed Direct Vendor Delivery (DVD) Program, blanket purchase agreements (BPA) would be put in place between GSA and vendors, with the aim of allowing customers to receive additional price discounts, save time, and reduce paperwork. Small businesses and others have raised concerns about the impact of the proposed shift to DVD on small businesses' …

Foster Care: State Practices for Assessing Health Needs, Facilitating Service Delivery, and Monitoring Children's Care (open access)

Foster Care: State Practices for Assessing Health Needs, Facilitating Service Delivery, and Monitoring Children's Care

A letter report issued by the Government Accountability Office with an abstract that begins "Providing health care services for foster children, who often have significant health care needs, can be challenging. The Administration for Children and Families (ACF) oversees foster care, but state child welfare agencies are responsible for ensuring that these children receive health care services, which are often financed by Medicaid. In light of concerns about the health care needs of foster children, GAO was asked to study states' efforts to improve foster children's receipt of health services. This report has four objectives. It describes specific actions that some states have taken to (1) identify health care needs, (2) ensure delivery of appropriate health services, and (3) document and monitor the health care of children in foster care. It also describes the related technical assistance ACF offers to states. To address these objectives, GAO selected 10 states and interviewed state officials and reviewed related documentation regarding the nature and results of the states' practices. To describe ACF's technical assistance, GAO interviewed officials and reviewed documents from ACF, states, and relevant technical assistance centers."

Highway Trust Fund: Improved Solvency Mechanisms and Communication Needed to Help Avoid Shortfalls in the Highway Account (open access)

Highway Trust Fund: Improved Solvency Mechanisms and Communication Needed to Help Avoid Shortfalls in the Highway Account

A letter report issued by the Government Accountability Office with an abstract that begins "The Highway Account within the Highway Trust Fund is the primary mechanism for funding federal highway programs. The account-- administered by the Federal Highway Administration (FHWA) within the Department of Transportation (DOT)--channels about $33 billion in highway user excise taxes annually to states for highway projects. Although DOT and others projected that the account could run out of funds in fiscal year 2009, the balance fell more rapidly than expected and a shortfall became imminent in August 2008. In September, Congress passed legislation to provide $8 billion to replenish the account, but DOT officials anticipate the account could reach a critical stage again in fiscal year 2009. This report (1) describes the events that led to the decline in the account balance, including how DOT responded, and (2) identifies potential improvements in mechanisms to manage account solvency. This report also includes information on strategies GAO has reported on in the past that could be used to better align account outlays and revenues. To conduct this work, GAO analyzed information in legal and budget documents, reviewed account estimates, and interviewed agency officials and stakeholders."

Long-Term Budget Issues: Moving From Balancing the Budget to Balancing Fiscal Risk

Testimony issued by the General Accounting Office with an abstract that begins "In this statement, the Comptroller General discusses the fiscal policy challenges facing Congress and the nation. The focus of tax administration and budgeting are shifting because of current and projected budget surpluses. The Comptroller General speaks of the need for fiscal responsibility when using surplus projections to design tax and spending policies. These projections are based on a set of assumptions that may or may not hold. They are not a precise prediction of a future and should be used as a reference point when making policy decisions. Although the projected surpluses can provide an opportunity to respond to pent-up demands for additional spending or tax cuts, Congress must balance those demands with the nation's long-term economic health."

Environmental Information: EPA Actions Could Reduce the Availability of Environmental Information to the Public

Testimony issued by the Government Accountability Office with an abstract that begins "U.S. industry uses billions of pounds of chemicals to produce the nation's goods and services. Releases of these chemicals during use or disposal can harm human health and the environment. The Emergency Planning and Community Right-to-Know Act of 1986 requires facilities that manufacture, process, or otherwise use more than specified amounts of nearly 650 toxic chemicals to report their releases to water, air, and land. The Environmental Protection Agency (EPA) makes this data available to the public in the Toxics Release Inventory (TRI). Since 1995, facilities may submit a brief certification statement (Form A), in lieu of the detailed Form R report, if their releases of specific chemicals do not exceed 500 pounds a year. In January 2007, EPA finalized a proposal to increase that threshold to 2,000 pounds, quadrupling what facilities can release before they must disclose their releases and other waste management practices. Today's testimony addresses (1) EPA's development of the proposal to change the TRI Form A threshold from 500 to 2,000 pounds and (2) the impact these changes may have on data available to the public. It also provides an update to our 2005 …

Preliminary Results from the UCLA/SLAC Ultra-High Gradient CerenkovWakefield Accelerator Experiment (open access)

Preliminary Results from the UCLA/SLAC Ultra-High Gradient CerenkovWakefield Accelerator Experiment

The first phase of an experiment to study the performance of dielectric Cerenkov wakefield accelerating structures at extremely high gradients in the GV/m range has been completed. This experiment takes advantage of the unique SLAC FFTB electron beam and its demonstrated ultra-short pulse lengths and high currents (e.g., {sigma}{sub z} = 20 {micro}m at Q = 3 nC). The FFTB electron beam has been successfully focused down and sent through varying lengths of fused silica capillary tubing with two different sizes: ID = 200 {micro}m/OD = 325 {micro}m and ID = 100 {micro}m/OD = 325 {micro}m. The pulse length of the electron beam was varied in the range 20 {micro}m < {sigma}{sub z} < 100 {micro}m which produced a range of electric fields between 2 and 20 GV/m at the inner surface of the dielectric tubes. We observed a sharp increase in optical emissions from the capillaries in the middle part of this surface field range which we believe indicates the transition between sustainable field levels and breakdown. If this initial interpretation is correct, the surfaced fields that were sustained equate to on axis accelerating field of several GV/m. In future experiments we plan to collect and measure coherent Cerenkov …

Geological Sequestration of CO2 by Hydrous Carbonate Formation with Reclaimed Slag (open access)

Geological Sequestration of CO2 by Hydrous Carbonate Formation with Reclaimed Slag

The concept of this project is to develop a process that improves the kinetics of the hydrous carbonate formation reaction enabling steelmakers to directly remove CO2 from their furnace exhaust gas. It is proposed to bring the furnace exhaust stream containing CO2 in contact with reclaimed steelmaking slag in a reactor that has an environment near the unit activity of water resulting in the production of carbonates. The CO2 emissions from the plant would be reduced by the amount sequestered in the formation of carbonates. The main raw materials for the process are furnace exhaust gases and specially prepared slag.

Habitat Evaluation Procedures (HEP) Report : Malheur River Wildlife Mitigation, 2000-2002 Technical Report. (open access)

Habitat Evaluation Procedures (HEP) Report : Malheur River Wildlife Mitigation, 2000-2002 Technical Report.

The development of hydropower systems within the Columbia and Snake River basins has affected a tremendous amount of fish and wildlife species. The dams have played a major role in the rapid extinction of anadromous runs of salmon and steelhead as well as other native salmonids. Inundation of these dams and the construction of reservoirs for irrigation have also severely impacted wildlife species. In some cases, fluctuating water levels caused by dam and reservoir operations have created barren vegetation zones that expose wildlife to predation and a reduction in recruitment. In association with hydropower activities, secondary impacts have also challenged and highly impacted a majority of wildlife species. The construction of roads, facilities, urban development, channelization, and diversions of streams and rivers often have negative long-term effects on fish, wildlife, and vegetation. In response to these concerns, the United States Congress passed the Pacific Electric Power Planning Conservation Act (Act) in 1980. The Act authorized four states (Idaho, Montana, Oregon and Washington) and 13 Indian Tribes (including the Burns Paiute Tribe) to create the Northwest Power Planning Council (Council). The role of the Council is to prepare a program in conjunction with several participants that protects, mitigates and enhances affected …
