Combating Nuclear Terrorism: Preliminary Observations on Preparedness to Recover from Possible Attacks Using Radiological or Nuclear Materials (open access)

Combating Nuclear Terrorism: Preliminary Observations on Preparedness to Recover from Possible Attacks Using Radiological or Nuclear Materials

Testimony issued by the Government Accountability Office with an abstract that begins "A terrorist's use of a radiological dispersal device (RDD) or improvised nuclear device (IND) to release radioactive materials into the environment could have devastating consequences. The timely cleanup of contaminated areas, however, could speed the restoration of normal operations, thus reducing the adverse consequences from an incident. This testimony examines (1) the extent to which federal agencies are planning to fulfill their responsibilities to assist cities and their states in cleaning up areas contaminated with radioactive materials from RDD and IND incidents; (2) what is known about the federal government's capability to effectively cleanup areas contaminated with radioactive materials from RDD and IND incidents, and (3) suggestions from government emergency management officials on ways to improve federal preparedness to provide assistance to recover from RDD and IND incidents. We also discuss recovery activities in the United Kingdom. This testimony is based on our ongoing review of recovery preparedness issues for which we examined applicable federal laws and guidance; interviewed officials from the Department of Homeland Security (DHS), Federal Emergency Management Agency (FEMA), Department of Energy (DOE), and Environmental Protection Agency (EPA); and surveyed emergency management officials from 13 …

Human Capital: Improved Tracking and Additional Actions Needed to Ensure the Timely and Accurate Delivery of Compensation and Medical Benefits to Deployed Civilians (open access)

Human Capital: Improved Tracking and Additional Actions Needed to Ensure the Timely and Accurate Delivery of Compensation and Medical Benefits to Deployed Civilians

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) and other executive agencies increasingly deploy civilians in support of contingency operations in Iraq and Afghanistan. Prior GAO reports show that the use of deployed civilians has raised questions about the potential for differences in policies on compensation and medical benefits. When these civilians are deployed and serve side by side, differences in compensation or medical benefits may become more apparent and could adversely impact morale. This statement is based on GAO's June 2009 congressionally requested report, which compared agency policies and identified any issues in policy or implementation regarding (1) compensation, (2) medical benefits, and (3) identification and tracking of deployed civilians. GAO reviewed laws, agency policies and guidance; interviewed responsible officials at the Office of Personnel Management (OPM) and the six selected agencies, including DOD and State; reviewed workers' compensation claims filed by deployed civilians with the Department of Labor from January 1, 2006 through April 30, 2008; and conducted a survey of deployed civilians. GAO made ten recommendations for agencies to take actions such as reviewing compensation laws and policies, establishing medical screening requirements, and creating mechanisms to assist and …

Federal Oil And Gas Management: Opportunities Exist to Improve Oversight (open access)

Federal Oil And Gas Management: Opportunities Exist to Improve Oversight

Testimony issued by the Government Accountability Office with an abstract that begins "In fiscal year 2008, the Department of the Interior collected over $22 billion in royalties and other fees related to oil and gas. Within Interior, the Bureau of Land Management (BLM) manages onshore federal oil and gas leases, and the Minerals Management Service's (MMS) Offshore Energy and Minerals Management (OEMM) manages offshore leases. A federal lease gives the lessee rights to explore for and develop the lease's oil and gas resources. MMS is responsible for collecting royalties for oil and gas produced from both onshore and offshore leases. GAO has reviewed federal oil and gas management and revenue collection and found many material weaknesses. This testimony is based primarily on key findings from past GAO reports and some preliminary findings from ongoing work. These findings focus on Interior's: (1) policies for oil and gas leasing, (2) oversight of oil and gas production, (3) royalty regime and policies to boost oil and gas development, (4) oil and gas information technology (IT) systems, and (5) royalty-in-kind program. GAO's past reports provided recommendations that Interior officials report that they are working to implement."

Homeland Security: Despite Progress, DHS Continues to Be Challenged in Managing Its Multi-Billion Dollar Annual Investment in Large-Scale Information Technology Systems

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) invested more than $6 billion in 2009 on large-scale, information technology (IT) systems to help it achieve mission outcomes and transform departmentwide operations. For DHS to effectively leverage these systems as mission enablers and transformation tools, it needs to employ a number of institutional acquisition and IT management controls and capabilities, such as using an operational and technological blueprint to guide and constrain system investments (enterprise architecture) and following institutional policies, practices, and structures for acquiring and investing in these systems. Other institutional controls and capabilities include employing rigorous and disciplined system life cycle management processes and having capable acquisition and IT management workforces. As GAO has reported, it is critical for the department to implement these controls and capabilities on each of its system acquisition programs. GAO has issued a series of reports on DHS institutional controls for acquiring and managing IT systems, and its implementation of these controls on large-scale systems. GAO was asked to testify on how far the department has come on both of these fronts, including its implementation of GAO's recommendations. To do this, GAO drew from …

Financial Regulation: Recent Crisis Reaffirms the Need to Overhaul the U.S. Regulatory System

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses issues relating to efforts to reform the regulatory structure of the financial system. In the midst of the worst economic crisis affecting financial markets globally in more than 75 years, federal officials have taken unprecedented steps to stem the unraveling of the financial services sector. While these actions aimed to provide relief in the short term, the severity of the crisis has shown clearly that in the long term, the current U.S. financial regulatory system was in need of significant reform. Our January 2009 report presented a framework for evaluating proposals to modernize the U.S. financial regulatory system, and work we have conducted since that report further underscores the urgent need for changes in the system. Given the importance of the U.S. financial sector to the domestic and international economies, in January 2009, we also added modernization of its outdated regulatory system as a new area to our list of high-risk areas of government operations because of the fragmented and outdated regulatory structure. We noted that modernizing the U.S. financial regulatory system will be a critical step to ensuring that the challenges of the 21st …

Personnel Security Clearances: Progress Has Been Made to Reduce Delays but Further Actions Are Needed to Enhance Quality and Sustain Reform Efforts

Testimony issued by the Government Accountability Office with an abstract that begins "Due to concerns about long standing delays in the security clearance process, Congress mandated reforms in the Intelligence Reform and Terrorism Prevention Act of 2004 (IRTPA), which requires, among other things, that the executive branch report annually to Congress. Since 2005, the Department of Defense's (DOD) clearance program has been on GAO's high-risk list due to delays and incomplete documentation. The Office of Personnel Management (OPM) conducts much of the government's clearance investigations. In 2007, the Director of National Intelligence and DOD established a Joint Reform Team to coordinate governmentwide improvement efforts for the process. The Office of Management and Budget (OMB) oversees these efforts. Based on two recent GAO reports, this statement addresses (1) progress in reducing delays at DOD, (2) opportunities for improving executive branch reports to Congress and (3) the extent to which joint reform efforts reflect key factors for reform. GAO independently analyzed DOD clearances granted in fiscal year 2008, assessed the executive branch's 2006-2009 reports to Congress, and compared three joint reform reports to key transformation practices. GAO previously recommended that OMB improve the transparency in executive branch reporting and establish a strategic …

Government Performance: Strategies for Building a Results-Oriented and Collaborative Culture in the Federal Government

Testimony issued by the Government Accountability Office with an abstract that begins "Since 1997, periodic GAO surveys indicate that overall, federal managers have more performance information available, but have not made greater use of this information for decision making. To understand the barriers and opportunities for more widespread use, GAO was asked to (1) examine key management practices in an agency in which managers' reported use of performance information has improved; (2) look at agencies with relatively low use of performance information and the factors that contribute to this condition; and (3) review the role the President and Congress can play in promoting a results-oriented and collaborative culture in the federal government. This testimony is primarily based on GAO's report, Results-Oriented Management: Strengthening Key Practices at FEMA and Interior Could Promote Greater Use of Performance Information, which is being released today. In this report, GAO made recommendations to the Departments of Homeland Security (DHS) and the Interior for improvements to key management practices to promote greater use of performance information at FEMA, the National Park Service, Bureau of Reclamation, as well as at Interior. Both DHS and Interior generally agreed with these recommendations. The testimony also draws from GAO's extensive …

High-Containment Laboratories: National Strategy for Oversight Is Needed (open access)

High-Containment Laboratories: National Strategy for Oversight Is Needed

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses our report on a national strategy for high-containment laboratories that deal with dangerous--pathogens also known as biosafety level-3 (BSL-3) laboratories and biosafety level-4 (BSL-4) laboratories--in the United States, which was released yesterday. The number of high-containment laboratories that work with dangerous biological pathogens have proliferated in recent years. In 2007, we reported on several issues associated with the proliferation of high-containment laboratories in the United States, including risks posed by biosafety incidents that have occurred in the past. The Federal Bureau of Investigation's allegation in August 2008 that a scientist at the U.S. Army Medical Research Institute of Infectious Diseases was the sole perpetrator of the 2001 anthrax attacks raised additional concerns about the possibility of insider misuse of high-containment laboratory facilities, material, and technology. The public is concerned about these laboratories because the deliberate or accidental release of biological agents can have disastrous consequences by exposing workers and the public to dangerous pathogens. Highly publicized laboratory errors and controversies about where high-containment laboratories should be located have raised questions about whether the governing framework, oversight, and standards for biosafety and biosecurity measures are adequate. …

Medicaid: Fraud and Abuse Related to Controlled Substances Identified in Selected States

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses (1) continuing indications of fraud and abuse related to controlled substances paid for by Medicaid; (2) specific case study examples of fraudulent, improper, or abusive controlled substance activity; and (3) the effectiveness of internal controls that the federal government and selected states have in place to prevent and detect fraud and abuse related to controlled substances. To identify whether there are continuing indications of fraud and abuse related to controlled substances paid for by Medicaid, we obtained and analyzed Medicaid claims paid in fiscal years 2006 and 2007 from five states: California, Illinois, New York, North Carolina, and Texas. To identify indications of fraud and abuse related to controlled substances paid for by Medicaid, we obtained and analyzed Medicaid prescription claims data for these five states from the Centers for Medicare & Medicaid Services (CMS). To identify other potential fraud and improper payments, we compared the beneficiary and prescriber shown on the Medicaid claims to the Death Master Files (DMF) from the Social Security Administration (SSA) to identify deceased beneficiaries and prescribers. To identify claims that were improperly processed and paid by the Medicaid program …

Military Readiness: DOD Needs to Strengthen Management and Oversight of the Defense Readiness Reporting System

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) reports data about the operational readiness of its forces. In 1999, Congress directed DOD to create a comprehensive readiness system with timely, objective, and accurate data. In response, DOD started to develop the Defense Readiness Reporting System (DRRS). After 7 years, DOD has incrementally fielded some capabilities, and, through fiscal year 2008, reported obligating about $96.5 million. GAO was asked to review the program including the extent that DOD has (1) effectively managed and overseen DRRS acquisition and deployment and (2) implemented features of DRRS consistent with legislative requirements and DOD guidance. GAO compared DRRS acquisition disciplines, such as requirements development, test management, and DRRS oversight activities, to DOD and related guidance, and reviewed the system's current and intended capabilities relative to legislative requirements and DOD guidance. We did not evaluate DOD's overall ability to assess force readiness or the extent that readiness data reflects capabilities, vulnerabilities, or performance issues."

Uncertainty and Sensitivity of Contaminant Travel Times from the Upgradient Nevada Test Site to the Yucca Mountain Area (open access)

Uncertainty and Sensitivity of Contaminant Travel Times from the Upgradient Nevada Test Site to the Yucca Mountain Area

Yucca Mountain (YM), Nevada, has been proposed by the U.S. Department of Energy as the nation’s first permanent geologic repository for spent nuclear fuel and highlevel radioactive waste. In this study, the potential for groundwater advective pathways from underground nuclear testing areas on the Nevada Test Site (NTS) to intercept the subsurface of the proposed land withdrawal area for the repository is investigated. The timeframe for advective travel and its uncertainty for possible radionuclide movement along these flow pathways is estimated as a result of effective-porosity value uncertainty for the hydrogeologic units (HGUs) along the flow paths. Furthermore, sensitivity analysis is conducted to determine the most influential HGUs on the advective radionuclide travel times from the NTS to the YM area. Groundwater pathways are obtained using the particle tracking package MODPATH and flow results from the Death Valley regional groundwater flow system (DVRFS) model developed by the U.S. Geological Survey (USGS). Effectiveporosity values for HGUs along these pathways are one of several parameters that determine possible radionuclide travel times between the NTS and proposed YM withdrawal areas. Values and uncertainties of HGU porosities are quantified through evaluation of existing site effective-porosity data and expert professional judgment and are incorporated in …
