Correspondence issued by the General Accounting Office with an abstract that begins "Medicare is highly vulnerable to fraud, waste, and abuse. The enforcement of program payment rules, however, has raised concerns that these safeguards may have imposed too great a burden on health care providers. The proposed Medicare Education and Regulatory Fairness Act would seek to address some of these concerns by providing expedited procedures for provider appeals, new options for providers to use in repaying Medicare overpayments, protections for providers who voluntarily return overpayments or ask for a review of their claims, and new requirements for provider education. This report reviews how this proposed legislation would affect Medicare policies and procedures in (1) provider education and participation, (2) medical reviews, audits, and appeals, (3) recovery of overpayments, and (4) related legal issues."

A letter report issued by the Government Accountability Office with an abstract that begins "Hurricane Katrina illustrated that effective preparation and response to a catastrophe requires a joint effort between federal, state, and local government. The Department of Homeland Security (DHS), through the Federal Emergency Management Agency (FEMA), is responsible for heading the joint effort. In January 2008, DHS released the National Response Framework (NRF), a revision of the 2004 National Response Plan (2004 Plan), the national preparation plan for all hazards. In response to the explanatory statement to the Consolidated Appropriations Act of 2008 and as discussed with congressional committees, this report evaluates the extent to which (1) DHS collaborated with non-federal stakeholders in revising and updating the 2004 Plan into the 2008 NRF and (2) FEMA has developed policies and procedures for managing future NRF revisions. To accomplish these objectives, GAO reviewed DHS and FEMA documents related to the revision process, analyzed the relevant statutes, and interviewed federal and non-federal officials who held key positions in the revision process."

A letter report issued by the Government Accountability Office with an abstract that begins "A highly pathogenic strain of avian influenza (AI) has spread to nearly 60 countries over the past few years, killing millions of birds and more than 170 humans. Controlling the virus in poultry is key to reducing the risk of a human pandemic. The Department of Agriculture (USDA) is responsible for planning for AI outbreaks in poultry, with states' assistance. The Department of Homeland Security (DHS) is responsible for coordinating the federal response for certain emergencies and developing policy documents that serve as a basis for national emergency planning. GAO described the steps USDA is taking to prepare for highly pathogenic AI and identified key challenges. GAO reviewed response plans, statutes, and regulations; visited poultry operations; interviewed federal, state, and industry officials in five states that experienced outbreaks; and reviewed 19 state plans."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Housing and Urban Development (HUD) provided over $6.7 billion in fiscal year 2008 to housing agencies to operate, modernize, and develop about 1.2 million public housing units. It is important that HUD exercise sufficient oversight of housing agencies to help ensure that public housing funds are being used as intended and properly managed. In this report, GAO examines HUD's oversight processes for detecting housing agencies at risk of inappropriate use and mismanagement of public housing funds. GAO analyzed HUD financial data on about 3,300 housing agencies, compared HUD's oversight policies with program and agency objectives, and interviewed agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Motor Carrier Safety Administration (FMCSA) has the primary federal responsibility for reducing crashes involving large trucks and buses that operate in interstate commerce. FMCSA decides which motor carriers to review for compliance with its safety regulations primarily by using an automated, data-driven analysis model called SafeStat. SafeStat uses data on crashes and other data to assign carriers priorities for compliance reviews. GAO assessed (1) the extent to which changes to the SafeStat model could improve its ability to identify carriers that pose high crash risks and (2) how the quality of the data used affects SafeStat's performance. To carry out its work, GAO analyzed how SafeStat identified high-risk carriers in 2004 and compared these results with crash data through 2005."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, the Federal Protective Service (FPS) transferred from the General Services Administration (GSA) to the Department of Homeland Security (DHS). FPS provides physical security and law enforcement services to about 9,000 GSA facilities. To accomplish its mission of protecting GSA facilities, FPS currently has an annual budget of about $1 billion, 1,100 employees, and 15,000 contract guards located throughout the country. Recently, FPS has faced several challenges protecting GSA facilities and federal employees. This report provides information and analysis on (1) FPS's operational challenges and actions it has taken to address them, (2) funding challenges FPS faces and actions it has taken to address them, and (3) how FPS measures the effectiveness of its efforts to protect GSA facilities. To address these objectives, we conducted site visits at 7 of FPS's 11 regions and interviewed FPS, GSA, tenant agencies, and local law enforcement officials."

Other written product issued by the General Accounting Office with an abstract that begins "The Core Financial System Requirements document is intended to assist agencies when reviewing new core financial systems and when improving or evaluating existing core financial systems. It provides the baseline functionality in order to support agency missions and comply with laws and regulations. The final issuance of this document will augment existing federal financial management system functional requirements used in assessing compliance with the Federal Financial Management Improvement Act."

A letter report issued by the General Accounting Office with an abstract that begins "The U.S. government owns about 3,500 properties overseas at more than 220 locations, including embassy and consular office buildings, housing, and land. The Department of State is responsible for acquiring, managing, and disposing of these properties. In 1996, GAO reported that the State Department did not have an effective process for identifying and selling unneeded overseas real estate, and that decisions concerning the sale of some properties had been delayed for years because of parochial conflicts among the parties involved. The State Department has taken steps to implement a more systematic process for identifying unneeded properties by (1) requesting posts to annually identify excess, underutilized, and obsolete property and (2) requesting its own staff and Inspector General officials to place greater emphasis on identifying such property when they visit posts. The State Department has significantly increased its sales of unneeded properties in the last 5 years. From 1997 through 2001, it sold 104 overseas properties for over $404 million, almost triple the proceeds compared with the previous 5 year period. However, the department still has a large number of unneeded properties that have not yet been …

Testimony issued by the General Accounting Office with an abstract that begins "The Department of Labor's Unemployment Insurance (UI) program is a federal-state partnership designed to partially replace lost earnings of individuals who become unemployed through no fault of their own and to stabilize the economy in times of economic downturn. The health of each state's UI program depends, in part, on their ability to control benefit payments by accurately determining eligibility for UI benefits in a timely manner. Labor's Office of Inspector General (OIG) and others have identified numerous aspects of the UI program that may be vulnerable to overpayments and fraud. Of the $30 billion in UI benefits paid in calendar year 2001, Labor estimates that this includes $2.4 billion in overpayments, including $560 million attributable to fraud or abuse. Labor's analysis also suggests that the states could have detected or recovered $1.3 billion of the total overpayments given their current policies and procedures. The management and operational practices at both the state and federal level contribute to overpayments in the UI program. At the state level, many states place a higher priority on quickly processing and paying UI claims than on taking the necessary steps to adequately …

Testimony issued by the General Accounting Office with an abstract that begins "Over the years, EPA has had persistent problems in managing its grants. Grants constituted one-half of the agency's annual budget, or about $4.2 billion in fiscal year 2002. EPA uses grants to implement its programs to protect human health and the environment and awards them to over 3,300 recipients, including state and local governments, tribes, universities, and nonprofit organizations. EPA's ability to efficiently and effectively accomplish its mission largely depends on how well it manages its grant resources and builds in accountability. Since 1996, GAO and EPA's Office of Inspector General have repeatedly reported on EPA's problems in managing its grants. Because these problems have persisted, in January 2003, GAO cited grants management as a major management challenge for EPA. GAO is currently reviewing EPA's efforts to improve grants management at the request of the Chairman of the House Committee on Transportation and Infrastructure and Representative Anne Northup. For this testimony GAO is reporting on results of its previously issued reports and on the grants problems EPA faces, past actions to address these problems, and recently issued EPA policies and a 5-year grants management plan to address its …

A letter report issued by the General Accounting Office with an abstract that begins "Senior Department of Defense (DOD) and military service officials have testified that they face increasing difficulties in carrying out realistic training at military installations. There are eight "encroachment" issues that affect or have the potential to affect military training and readiness. The eight encroachment issues are: endangered species habitat on military installations, unexploded ordnance and munitions constituents, competition for radio frequency spectrum, protected marine resources, competition for airspace, air pollution, noise pollution, and urban growth around military installations. Whenever possible, the services work around these issues by modifying the timing, tempo, and location of training, as well as the equipment used. However, these workarounds are becoming increasingly difficult and costly and they compromise the realism essential to effective training. Over time, the military services report they have increasingly lost training range capabilities because of encroachment. Each of the four installations and two major commands GAO visited reported having lost some capabilities in terms of the time training ranges were available or the types of training that could be conducted. Higher-than-average population growth around installations makes further encroachment losses likely. Despite the loss of some capabilities, service …

Testimony issued by the Government Accountability Office with an abstract that begins "The Homeland Security Act was enacted in November 2002, creating the Department of Homeland Security (DHS) to improve homeland security following the September 11, 2001, terrorist attacks on the United States. The act centralized the leadership of many homeland security activities under a single federal department and, accordingly, DHS has the dominant role in implementing this national strategy. This testimony discusses the status of DHS's actions in fulfilling its responsibilities to (1) establish policies to define roles and responsibilities for national emergency preparedness efforts and prepare for the transition between presidential administrations, and (2) develop operational plans and performance metrics to implement these roles and responsibilities and coordinate federal resources for disaster planning and response. This testimony is based on prior GAO work performed from September 2006 to June 2008 focusing on DHS's efforts to address problems identified in the many post-Katrina reviews."

Testimony issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) contains EPA's scientific position on the potential human health effects of exposure to more than 540 chemicals. Toxicity assessments in the IRIS database constitute the first two critical steps of the risk assessment process, which in turn provides the foundation for risk management decisions. Thus, IRIS is a critical component of EPA's capacity to support scientifically sound environmental decisions, policies, and regulations. GAO's 2008 report on the IRIS program identified significant concerns that, coupled with the importance of the program, caused GAO to add EPA's processes for assessing and controlling toxic chemicals as a high-risk area in its January 2009 biennial status report on governmentwide high-risk areas requiring increased attention by executive agencies and Congress. This testimony discusses (1) the findings from GAO's March 2008 report Chemical Assessments: Low Productivity and New Interagency Review Process Limit the Usefulness and Credibility of EPA's Integrated Risk Information System and related testimonies and (2) GAO's preliminary evaluation of the revised IRIS assessment process EPA issued on May 21, 2009. For this testimony, GAO supplemented its prior audit work with a preliminary …

A letter report issued by the General Accounting Office with an abstract that begins "The Personal Responsibility and Work Opportunity Reconciliation Act (PRWPRA) of 1996 changed the nation's cash assistance program for needy families with children. The former program, Aid to Families with Dependent Children (AFDC), was replaced with the Temporary Assistance for Needy Families (TANF) block grant, which provides states with $16.5 billion each year through 2002 to serve this population. TANF's goals include ending the dependence of needy families on government benefits by promoting job preparation, work, and marriage; preventing and reducing the incidence of nonmarital pregnancies; and encouraging two-parent families. PRWORA expanded the scope of services that could potentially be contracted out, such as determining eligibility for TANF, which had traditionally been done by government employees. Moreover, with the large drop in TANF caseloads nationally, a greater share of federal TANF block grant funds and state funds is now devoted to various support services that are typically contracted out. Although PRWORA expanded the flexibility of states to design and administer TANF programs, its also limited the ability of the Department of Health and Human Services (HHS) to regulate states' TANF programs. Contracting with nongovernmental entities to provide …

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses Social Security Administration (SSA) improvements in the claims process for its two disability programs, Disability Insurance (DI) and Supplemental Security Income (SSI). Managing its disability caseloads with fair, consistent, and timely eligibility decisions in the face of resource constraints has become one of SSA's most pressing management challenges. SSA has spent more than $39 million over the past 7 years to test and implement initiatives designed to improve the timeliness, accuracy, and consistency of its disability decisions and to make the process more efficient and understandable for claimants. These have included efforts to improve the initial claims process as well as handling appeals of denied claims. The results to date have been disappointing. SSA's two tests to improve the initial claims process produced some benefits; however, both initiatives as tested would have significantly raised costs, and one would have lengthened the wait for final decisions for many claimants. As a result, SSA is considering additional changes to one of these initiatives and has shelved the other. One initiative to change the process for handling appealed claims in SSA's hearing offices has resulted in even slower …

Testimony issued by the General Accounting Office with an abstract that begins "As new technologies that depend on the radio spectrum continue to be developed and used more widely, managing the spectrum can grow increasingly challenging. The current legal framework for domestic spectrum management evolved as a compromise over the questions of who should determine the distribution of the spectrum among competing users and what standard should be applied in making this determination. Although initially, all responsibility for spectrum management was placed in the executive branch, this responsibility has been divided between the executive branch for managing federal use and an independent commission for managing non-federal use since 1927 . The current shared U.S. spectrum management system has processes for allocating spectrum, but these processes have occasionally resulted in lengthy negotiations between the Federal Communications Commission and the National Telecommunications and Information Administration (NTIA) over allocation issues. The United States also faces challenges in effectively preparing for World Radiocommunication Conferences. NTIA has several activities to encourage efficient spectrum use by federal agencies, but it lacks the assurance that these activities are effective. NTIA is required to promote efficiency in the federal spectrum it manages, which included more than 270,000 federal …

Testimony issued by the Government Accountability Office with an abstract that begins "On April 3, 2008, the Secretary of Commerce announced significant changes to how the Census Bureau (Bureau) would conduct nonresponse follow-up, its largest field operation, in which census workers interview households that do not return initial census forms for the 2010 decennial census, and to its Field Data Collection Automation (FDCA) contract. The Bureau has since issued a redesigned plan to conduct a paper-based follow-up operation, an integrated 2010 Census project schedule, and is working on revising the FDCA contract. These are major changes late in the decennial census cycle. This testimony discusses (1) the Bureau's plans for conducting a paper-based nonresponse follow-up operation, (2) management of the FDCA contract and its latest cost estimates, and (3) the status of the Bureau's integrated 2010 project schedule. This testimony is based on past work, recent interviews with Bureau officials, and a review of redesign documents."

The paper describes work to enable improved energy performance of existing and new retail stores belonging to a national chain and thereby also identify measures and tools that would improve the performance of 'big box' stores generally. A detailed energy simulation model of a standard store design was developed and used to: (1) demonstrate the benefits of benchmarking the energy performance of retail stores of relatively standard design using baselines derived from simulation, (2) identify cost-effective improvements in the efficiency of components to be incorporated in the next design cycle, and (3) use simulation to identify potential control strategy improvements that could be adopted in all stores, improving operational efficiency. The core enabling task of the project was to develop an energy model of the current standard design using the EnergyPlus simulation program. For the purpose of verification of the model against actual utility bills, the model was reconfigured to represent twelve existing stores (seven relatively new stores and five older stores) in different US climates and simulations were performed using weather data obtained from the National Weather Service. The results of this exercise, which showed generally good agreement between predicted and measured total energy use, suggest that dynamic benchmarking …

Under the auspices of the U.S. Department of Energy (USDOE), researchers from the Lawrence Livermore National Laboratory (LLNL) have recently implemented a series of initiatives to address long-term radiological surveillance needs at former nuclear test sites in the Republic of the Marshall Islands (RMI). The aim of this radiological surveillance monitoring program (RSMP) is to provide timely radiation protection for individuals in the Marshall Islands with respect to two of the most important internally deposited fallout radionuclides-cesium-137 ({sup 137}Cs) and long-lived isotopes 239 and 240 of plutonium ({sup 239+240}Pu) (Robison et al., 1997 and references therein). Therefore, whole-body counting for {sup 137}Cs and a sensitive bioassay for the presence of {sup 239+240}Pu excreted in urine were adopted as the two most applicable in vivo analytical methods to assess radiation doses for individuals in the RMI from internally deposited fallout radionuclides (see Hamilton et al., 2006a-c; Bell et al., 2002). Through 2005, the USDOE has established three permanent whole-body counting facilities in the Marshall Islands: the Enewetak Radiological Laboratory on Enewetak Atoll, the Utrok Whole-Body Counting Facility on Majuro Atoll, and the Rongelap Whole-Body Counting Facility on Rongelap Atoll. These whole-body counting facilities are operated and maintained by trained Marshallese technicians. …

The 100-C-9:1 main process sewer pipeline, also known as the twin box culvert, was a dual reinforced process sewer that collected process effluent from the 183-C and 190-C water treatment facilities, discharging at the 132-C-2 Outfall. For remedial action purposes, the 100-C-9:1 waste site was subdivided into northern and southern sections. The 100-C-9:1 subsite has been remediated to achieve the remedial action objectives specified in the Remaining Sites ROD. The results of verification sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.
