A letter report issued by the General Accounting Office with an abstract that begins "Political appointees in the federal government sometimes seek appointments to career positions, which do not end with an administration. Although merit system principles require that selections be determined solely on the basis of merit after fair and open competition, questions have been raised about whether some individuals have received political favoritism or an unfair advantage, even the appearance of which could adversely compromise the integrity of the system. The 45 agencies GAO surveyed reported that 100 employees converted from political appointments and 11 converted from congressional staff positions from October 1998 through April 2001. All the conversions took place at 21 agencies. Ninety-five of the 111 conversions were to positions at the GS-12 level and above. GAO found that the 21 agencies used appropriate appointment authorities, such as civil service certificates from the competitive selection process, and generally followed merit system procedures. In 17 instances, however, the appointments could give the appearance that individuals had received political favoritism or preferences."

A chapter report issued by the General Accounting Office with an abstract that begins "The 2001 outbreak of foot and mouth disease (FMD) in the United Kingdom decisively illustrated the devastation that this highly contagious animal disease can cause to a nation's economy. By the time the disease was eradicated, the United Kingdom had slaughtered more than 4 million animals and sustained losses of $5 billion in the food and agricultural sectors, as well as comparable losses to its tourism industry. Before 2001, the United Kingdom had been FMD-free for almost 34 years. Following the outbreak, the country was generally barred from participating in the international trade of live animals and animal products that could transmit the virus. The United States has adequate processes for obtaining information on foreign FMD outbreaks and providing the Department of Agriculture (USDA) and others with this information, but it lacks adequate processes for sharing this information with the Customs Service. The United States receives information on FMD outbreaks from USDA officials stationed abroad, international agricultural and animal health organizations, and foreign governments. These officials collect a wide array of agricultural and animal health information about the countries and regions in which they are stationed, …

A briefing report issued by the General Accounting Office with an abstract that begins "Congress responded to the attacks of September 11, 2001, with dramatic funding increases to combat terrorism. Even before these attacks, Congress was concerned about increased funding in this area, and based on findings from a 1997 GAO report, mandated that the Office of Management and Budget (OMB) report annually on funding to combat terrorism. In this review, GAO was asked to analyze such funding trends, describe difficulties in coordinating combating terrorism budgets, assess data reported to Congress, and describe the executive branch's efforts to maximize the effective use of combating terrorism funds. The review relied on OMB's definition of "combating terrorism" to include both homeland security and overseas combating terrorism missions."

A letter report issued by the General Accounting Office with an abstract that begins "As the baby boomers age, spending on long-term care for the elderly could quadruple by 2050. The growing demand for long-term care will put pressure on federal and state budgets because long-term care relies heavily on public financing, particularly Medicaid. Nursing home care traditionally has accounted for most Medicaid long-term care expenditures, but the high costs of such care and the preference of many individuals to stay in their own homes has led states to expand their Medicaid programs to provide coverage for home- and community-based long-term care. GAO found that a Medicaid-eligible elderly individual with the same disabling conditions, care needs, and availability of informal family support could find significant differences in the type and intensity of home and community-based services that would be offered for his or her care. These differences were due in part to the very nature of long-term care needs--which can involve physical or cognitive disabling conditions--and the lack of a consensus as to what services are needed to compensate for these disabilities and what balance should exist between publicly available and family-provided services. The differences in care plans were also …

A letter report issued by the General Accounting Office with an abstract that begins "Before 1850, an estimated 16 million salmon and steelhead returned to the Columbia River Basin annually to spawn. Over the past 25 years, the number of salmon and steelhead returning to the Columbia River Basin has averaged only 660,000 per year although annual population levels have varied widely. Factors such as over-harvesting, construction and operation of dams, degradation of spawning habitat, increased human population, and unfavorable weather and ocean conditions have contributed to the long-term decline. The population decline has resulted in the listing of 12 salmon and steelhead populations in the basin as threatened or endangered under the Endangered Species Act. Once a species is listed as threatened or endangered, the act requires that efforts be taken to allow its recovery. Eleven federal agencies are involved with salmon and steelhead recovery efforts in the Columbia River Basin. The National Marine Fisheries Service (NMFS), as the lead agency, is responsible for preparing a recovery plan and consulting with the other federal agencies on their planned actions. The 11 federal agencies estimate expenditures of $1.8 billion from fiscal year 1982 through fiscal year 1996 and $1.5 billion …

A letter report issued by the General Accounting Office with an abstract that begins "Day laborers generally are individuals who work and get paid on a daily or short-term basis. To find work, they often congregate on street corners and wait for employers to drive by and offer them work. Day laborers may also be employed by temporary staffing agencies that assign them work on a daily basis with client employers. Day laborers have an informal relationship with the labor market, often working for different employers each day, being paid in cash, and lacking key benefits, such as health or unemployment insurance. However, day laborers may be eligible for wage and safety protections provided by the Fair Labor Standards Act (FLSA) and the Occupational Safety and Health (OSH) Act. The U.S. Department of Labor administers both acts. Its Wage and Hour Division (WHD) is responsible for ensuring that all covered workers receive at least the federal minimum hourly wage and overtime pay. The Occupational Safety and Health Administration (OSHA) is required to ensure that employers provide safe and healthy workplaces to help their workers avoid injury or death. Coverage under both laws does not depend on a worker's immigration status. …

A letter report issued by the General Accounting Office with an abstract that begins "The Office of Pipeline Safety (OPS) is implementing a new approach to overseeing the safety of a 2.2-million-mile network of pipelines in the United States that transports potentially dangerous materials, including hazardous liquids, such as oil and natural gas. OPS has to complete several important steps to implement its integrity management approach within an ambitious, self-imposed schedule. The agency began applying this new regulatory approach to hazardous liquid pipelines in 2000 by issuing final rules requiring operators of these pipelines to develop integrity management programs. While implementing its integrity management approach, OPS must also perform ongoing oversight duties, such as inspecting the construction of new pipelines and investigating pipeline incidents. In addition to meeting its ambitious schedule, OPS faces a number of other challenges in implementing this new regulatory approach. These challenges include (1) enforcing the integrity management requirements consistently and effectively, (2) ensuring that natural gas transmission pipeline operators use assessment methods appropriately, (3) establishing an inspection interval for natural gas transmission pipelines, (4) measuring and reporting on the effectiveness of the approach, and (5) developing and implementing an approach for overseeing pipeline security. OPS's …

A letter report issued by the General Accounting Office with an abstract that begins "This report examines the acquisition of the Composite Health Care System (CHCS) II. It is one in a series of reports reviewing the Department of Defense's use of best practices in acquiring information technology systems. CHCS II is expected to cost about $1 billion to deliver full capability to almost 1,100 health facilities worldwide by 2008. GAO's objectives were to determine (1) what progress has been made against project commitments, (2) whether the system has been economically justified, and (3) whether effective technical and management controls are in place."

A letter report issued by the General Accounting Office with an abstract that begins "In examining the efforts of the Departments of Education, Housing and Urban Development, and Transportation to ensure that recipients corrected single audit report findings, GAO found that each agency had procedures for obtaining and distributing the audit reports to appropriate officials for action. However, they often did not issue the required written management decisions or have documentary evidence of their evaluations of and conclusions on recipients' actions to correct the audit findings. In addition, program managers did not summarize and communicate information on single audit results and recipient actions to correct audit findings to agency management."

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) downsized its acquisition workforce by half in the past decade. It now faces serious imbalances in the skills and experience of its remaining workforce and the potential loss of highly specialized knowledge if many of its acquisition specialists retire. DOD created the Acquisition 2005 Task Force to study its civilian acquisition workforce and develop a strategy to replenish personnel losses. In response to a legislative mandate, DOD reported on its plans to implement the task force's recommendations as required by the National Defense Authorization Act for Fiscal Year 2002. DOD's report shows that it has made progress in reshaping its acquisition workforce. For example, DOD is working to remove barriers to its strategic planning initiative; continuing to test various human capital innovations; and has begun making significant changes to its acquisition workforce-training program. DOD's report provides information on implementation of the task force's recommendations and their status. However, for many initiatives, DOD did not clearly describe the actions taken or when they occurred, nor did it identify all planned actions and schedules for completing the initiatives."

A letter report issued by the General Accounting Office with an abstract that begins "To increase child support collections, Congress has considered proposals to improve the ability of private firms to gather information to help locate noncustodial parents and enforce the payment of child support. At the end of fiscal year 2000, the Office of Child Support Enforcement (OCSE) indicated that $89 billion in child support was owed but unpaid--a 96-percent increase since the end of fiscal year 1996. GAO believes that this amount is understated. Thousands of private and public sector entities can collect child support. Both private firms and state agencies reported collections from about 60 percent of their cases. Twenty-two of the 24 private firms GAO reviewed reported that they relied on private information vendors--commercial firms that sell information such as addresses, telephone numbers, and social security numbers--as their primary information source, whereas about one-third of state agencies reported using this source. State agencies relied heavily on state and federal automated databases to locate noncustodial parents and their assets. Additionally, private firms and the state agencies reported calling noncustodial parents to collect child support. However, only the private firms called third parties, such as relatives and neighbors …

A letter report issued by the General Accounting Office with an abstract that begins "The Federal Courts Administration Act of 1992 requires GAO to review certain aspects of the Judicial Survivors' Annuities System (JSAS), one of several survivor benefit plans applicable to federal employees. JSAS provides annuities to surviving spouses and dependent children of deceased Supreme Court Justices, judges of the United States, and other participating judicial officials. For the 3 years covered by GAO's review, the judges' contributions represented more than 50 percent of the JSAS normal costs for fiscal year 1999, but less than 50 percent for fiscal years 2000 and 2001. To cover 50 percent of JSAS estimated future normal costs, the judges' contributions would need to increase by 0.1 percentage point above the 2.2 percent of salaries paid by retired judges. However, increasing required contributions could reduce the judges' rate of participation even though increasing participation was one of the main reasons for enhancing JSAS benefits and reducing judges' contributions in 1992."

A letter report issued by the General Accounting Office with an abstract that begins "This report discusses the budgetary implications of selected program reforms discussed in GAO work but not yet implemented or enacted. To help congressional budget and appropriations committees identify ways to reduce federal spending or increase revenues, this year's report contains more than 100 examples of budget options organized by budget function. Where possible, budgetary savings estimates provided by the Congressional Budget Office or the Joint Committee on Taxation are presented."

A letter report issued by the General Accounting Office with an abstract that begins "Dioxins--chemical compounds that share structural and biological characteristics--have been linked to human illnesses, including cancer. Often the byproducts of combustion and industrial processes, complex mixtures of dioxins enter the food chain and human diet through emissions into the air. The Environmental Protection Agency (EPA) and the World Health Organization (WHO) noted the potential human health risks of dioxins in the 1970s when animal studies showed them to be among the most potent cancer-causing chemicals. EPA derived its estimates of human dietary exposure to dioxins in the United States from (1) chemically analyzed samples of 10 food types, (2) toxicity estimates of levels of individual dioxins in these foods, and (3) estimates of the quantities of these foods consumed by Americans. To develop more reliable national estimates of dietary exposure, EPA incorporated into its analysis some food studies that were nationally representative. Although both EPA and the WHO have assessed the human health risks of dioxins during the last decade, some of their objectives and processes have differed. Nonetheless, the analytical methods used and the conclusions reached have much in common. A major difference in the assessments …

The goal of the radiation modeling effort was to develop and implement a radiation algorithm that is fast and accurate for the underhood environment. As part of this CRADA, a net-radiation model was chosen to simulate radiative heat transfer in an underhood of a car. The assumptions (diffuse-gray and uniform radiative properties in each element) reduce the problem tremendously and all the view factors for radiation thermal calculations can be calculated once and for all at the beginning of the simulation. The cost for online integration of heat exchanges due to radiation is found to be less than 15% of the baseline CHAD code and thus very manageable. The off-line view factor calculation is constructed to be very modular and has been completely integrated to read CHAD grid files and the output from this code can be read into the latest version of CHAD. Further integration has to be performed to accomplish the same with STAR-CD. The main outcome of this effort is to obtain a highly scalable and portable simulation capability to model view factors for underhood environment (for e.g. a view factor calculation which took 14 hours on a single processor only took 14 minutes on 64 processors). …

The Ashtabula Environmental Management Project (AEMP) at Department of Energy-Ohio (DOE-OH) requested technical assistance from the EM-50 Lead Lab to aid in defining new cost and time effective approaches in the following problem areas: soils, concrete, and groundwater/Corrective Action Management Unit (CAMU) at RMIES in Ashtabula, Ohio. Attachment 1 provides the site request for assistance. The technical assistance team assembled for this request is provided in Attachment 2. These individuals reviewed key site information prior to convening with DOE and contractor personnel (RMIES and Earthline) for a three-and-a-half-day meeting to better understand baseline technologies, limitations, and site-specific issues. After listening to presentations about the nature and extent of known contamination, the team broke out into several groups to brainstorm ideas and develop viable solutions. This executive summary details unresolved issues requiring management attention as well as recommendations to address soils, concrete, and groundwater/CAMU. It also provides a summary of additional technical assistance that could be provided to the site. More details are presented in the body of this report.

For more than half a century, since nuclear science helped us win World War II and ring in the Atomic Age, scientists have known that !he Nation would need a secure, permanent facility in which to dispose of radioactive wastes. Twenty years ago, when Congress adopted the Nuclear Waste Policy Act of 1982 (NWPA or ''the Act''), it recognized the overwhelming consensus in the scientific community that the best option for such a facility would be a deep underground repository. Fifteen years ago, Congress directed the Secretary of Energy to investigate and recommend to the President whether such a repository could be located safely at Yucca Mountain, Nevada. Since then, our country has spent billions of dollars and millions of hours of research endeavoring to answer this question. I have carefully reviewed the product of this study. In my judgment, it constitutes sound science and shows that a safe repository can be sited there. I also believe that compelling national interests counsel in favor of proceeding with this project. Accordingly, consistent with my responsibilities under the NWPA, today I am recommending that Yucca Mountain be developed as the site for an underground repository for spent fuel and other radioactive wastes. …

Anode-supported cells comprising Ni + yttria-stabilized zirconia (YSZ) anode, thin ({approx}10 {micro}m) YSZ electrolyte, and composite cathodes containing a mixture of La{sub 0.8}Sr{sub 0.2}MnO{sub (3-{delta})} (LSM) and La{sub 0.9}Sr{sub 0.1}Ga{sub 0.8}Mg{sub 0.2}O{sub (3-{lambda})} (LSGM) were fabricated. The relative proportions of LSGM and LSM were varied between 30 wt.% LSGM + 70 wt.% LSM and 70 wt.% LSGM + 30 wt.% LSM, while the firing temperature was varied between 1000 and 1200 C. The cathode interlayer composition had a profound effect on cathode performance at 800 C with overpotentials ranging between 60 and 425 mV at 1.0 A/cm{sup 2} and exhibiting a minimum for 50 wt.% LSGM + 50 wt.% LSM. The cathodic overpotential decreased with increasing firing temperature of the composite interlayer in the range 1000 {le} T {le} 1150 C, and then increased dramatically for the interlayer fired at 1200 C. The cell with the optimized cathode interlayer of 50 wt.% LSM + 50 wt.% LSGM fired at 1150 C exhibited an area specific cell resistance of 0.18 {Omega}cm{sup 2} and a maximum power density of 1.4 W/cm{sup 2} at 800 C. Chemical analysis revealed that LSGM reacts with YSZ above 1000 C to form the pyrochlore phase, La{sub …

Because of the possibility of an enriched uranium spill in transit, a program has been initiated to develop safer methods of shipment. This report compares uranium on resin with conversion to unpurified UO3, and provides information needed to judge the relative merits of the processes to produce these two solid forms.

In this work, solvent recovery from aqueous CSSX process raffinate effluent was tested using the process diluent (Isopar{reg_sign}L). A model was developed to obtain stage efficiency for the diluent contact stages. The model was used to fit experimental data from a 19.8-hr solvent recovery test. Diluent-in-aqueous entrainment was measured during the test. Vacuum distillation was used to concentrate the solvent components, BOBCalixC6 and modifier, in the diluent used in solvent recovery. Using the results, a feasibility study was performed to compare the annual cost of lost solvent under each of four solvent recovery options. These options were decanter tank, centrifuge, two-stage diluent contact using centrifugal contactor, and no solvent recovery action.
