Border Security: Key Unresolved Issues Justify Reevaluation of Border Surveillance Technology Program

A letter report issued by the Government Accountability Office with an abstract that begins "In September 2004, the Department of Homeland Security (DHS) established America's Shield Initiative (ASI)--a program that included a system of sensors, cameras, and databases formerly known as the Integrated Surveillance Intelligence System (ISIS)--to detect, characterize, and deter illegal breaches to the northern and southern U.S. borders. The goals of the ASI program were to address ISIS capability limitations and support the department's antiterrorism mission. In April 2005, department officials told GAO that ISIS was subsumed within ASI. By congressional mandate, GAO reviewed the program to determine (1) the operational needs that ASI was intended to address and DHS's plans for ASI, (2) the steps that DHS had taken to ensure that ASI was aligned with the department's enterprise architecture, and (3) the actions that DHS had taken to establish the capability to effectively manage ASI. In written comments, DHS agreed with a draft of this report, stating that it was factually correct in virtually all aspects. DHS also commented that it has ceased work on ASI and redirected resources to its Secure Border Initiative. It also described program management corrective actions that it plans to implement."

Food Safety: Experiences of Seven Countries in Consolidating Their Food Safety Systems (open access)

Food Safety: Experiences of Seven Countries in Consolidating Their Food Safety Systems

A letter report issued by the Government Accountability Office with an abstract that begins "The safety and quality of the U.S. food supply are governed by a complex system that is administered by 15 agencies. The U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA), within the Department of Health and Human Services (HHS), have primary responsibility for food safety. Many legislative proposals have been made to consolidate the U.S. food safety system, but to date no other action has been taken. Several countries have taken steps to streamline and consolidate their food safety systems. In 1999, we reported on the initial experiences of four of these countries--Canada, Denmark, Ireland, and the United Kingdom. Since then, additional countries, including Germany, the Netherlands, and New Zealand, have undertaken consolidations. This report describes the approaches and challenges these countries faced in consolidating food safety functions, including the benefits and costs cited by government officials and other stakeholders. In commenting on a draft of this report, HHS and USDA said that the countries' consolidation experiences have limited applicability to the U.S. food safety system because the countries are much smaller than the United States. The two agencies believe that they …

Disaster Cost Estimates: FEMA Can Improve Its Learning from Past Experience and Management of Disaster-Related Resources (open access)

Disaster Cost Estimates: FEMA Can Improve Its Learning from Past Experience and Management of Disaster-Related Resources

A letter report issued by the Government Accountability Office with an abstract that begins "Public Law No. 110-28 directed GAO to review how the Federal Emergency Management Agency (FEMA) develops its disaster cost estimates. Accordingly, GAO addressed the following questions: (1) What is FEMA's process for developing and refining its cost estimates for any given disaster? (2) From 2000 through 2006, how close have cost estimates been to the actual costs for noncatastrophic (i.e., federal costs under $500 million) natural disasters? (3) What steps has FEMA taken to learn from past experience and improve its management of disaster-related resources and what other opportunities exist? To accomplish this, GAO reviewed relevant FEMA documents and interviewed key officials. GAO also obtained and analyzed disaster cost data and determined that they were sufficiently reliable for the purposes of this review."

Debt Collection Improvement Act of 1996: HHS's Centers for Medicare & Medicaid Services Faces Challenges to Fully Implement Certain Key Provisions (open access)

Debt Collection Improvement Act of 1996: HHS's Centers for Medicare & Medicaid Services Faces Challenges to Fully Implement Certain Key Provisions

A letter report issued by the General Accounting Office with an abstract that begins "The Debt Collection Improvement Act (DCIA) of 1996 requires that agencies refer eligible debts delinquent more than 180 days that they have been unable to collect to the Department of the Treasury for payment and offset and to Treasury or a Treasury-designated debt collection center for cross-servicing. The Centers for Medicare and Medicaid Services (CMS) made progress in referring eligible delinquent debts for collection during fiscal year 2001. Much of the referral volume was late in the year, however, and substantial unreferred balances remained at the end of the fiscal year. Inadequate procedures and controls hampered prompt identification and referral of both eligible non-Medicare Secondary Payer (MSP) and MSP debts. The delayed referral of non-MSP debts resulted from problems with the CMS debt-referral system and insufficient CMS monitoring of contractor referrals. The low level of MSP debt referrals resulted primarily from limited contractor efforts and insufficient CMS monitoring of contractor performance. Although GAO did not test whether selected CMS debts had been reasonably excluded from referral and reached no overall conclusion about the appropriateness of CMS exclusions, GAO found that CMS did not report reliable Medicare …

Maritime Security: Public Safety Consequences of a Terrorist Attack on a Tanker Carrying Liquefied Natural Gas Need Clarification

A letter report issued by the Government Accountability Office with an abstract that begins "The United States imports natural gas by pipeline from Canada and by tanker as liquefied natural gas (LNG) from overseas. LNG--a supercooled form of natural gas--currently accounts for about 3 percent of total U.S. natural gas supply, with an expected increase to about 17 percent by 2030, according to the Department of Energy (DOE). With this projected increase, many more LNG import terminals have been proposed. However, concerns have been raised about whether LNG tankers could become terrorist targets, causing the LNG cargo to spill and catch on fire, and potentially explode. DOE has recently funded a study to consider these effects; completion is expected in 2008. GAO was asked to (1) describe the results of recent studies on the consequences of an LNG spill and (2) identify the areas of agreement and disagreement among experts concerning the consequences of a terrorist attack on an LNG tanker. To address these objectives, GAO, among other things, convened an expert panel to discuss the consequences of an attack on an LNG tanker."

Medicare Advantage: Increased Spending Relative to Medicare Fee-for-Service May Not Always Reduce Beneficiary Out-of-Pocket Costs

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, the federal government spent about $59 billion on Medicare Advantage (MA) plans, an alternative to the original Medicare fee-for-service (FFS) program. Although health plans were originally envisioned in the 1980s as a potential source of Medicare savings, such plans have generally increased program spending. Payments to MA plans have been estimated to be 12 percent greater than what Medicare would have spent in 2006 had MA beneficiaries been enrolled in Medicare FFS. Some policymakers are concerned about the cost of the MA program and its contribution to overall spending on the Medicare program, which already faces serious long-term financial challenges. MA plans receive a per member per month (PMPM) payment to provide services covered under Medicare FFS. Almost all MA plans receive an additional Medicare payment, known as a rebate. Plans use rebates and sometimes additional beneficiary premiums to fund benefits not covered under Medicare FFS, reduce premiums, or reduce beneficiary cost sharing. This report examines for 2007 (1) MA plans' projected rebate allocations; (2) additional benefits MA plans commonly covered and their costs; (3) MA plans' projected cost sharing; and (4) MA plans' …

Limitations in DOD's Evaluation Plan for EEO Complaint Pilot Program Hinder Determination of Pilot Results (open access)

Limitations in DOD's Evaluation Plan for EEO Complaint Pilot Program Hinder Determination of Pilot Results

Correspondence issued by the Government Accountability Office with an abstract that begins "In August 2004, pursuant to Section 1111 of the fiscal year 2001 Department of Defense authorization act, the Secretary of Defense authorized components of the United States Air Force (USAF), the Defense Logistics Agency (DLA), and the Defense Commissary Agency (DeCA) to implement an equal employment opportunity (EEO) complaint pilot program to reengineer the EEO complaint process to, among other things, reduce complaint processing time and reinforce management accountability. The program was exempt from the procedural requirements of 29 C.F.R. Part 1614 and other regulations, directives, or regulatory restrictions prescribed by the Equal Employment Opportunity Commission (EEOC). As required by the legislation, in May 2006, GAO reported on the implementation of the pilot programs and found that two of the three pilot initiatives operated consistent with existing EEOC requirements, with a specific emphasis on alternative dispute resolution (ADR). USAF's pilot operated outside of EEOC regulations, as authorized under the legislation. We identified limitations in the Department of Defense's (DOD) evaluation plan for the pilot program that, if not addressed, would limit the likelihood that the evaluation would yield sound results. For example, the plan did not have well-defined …

Biological Research Laboratories: Issues Associated with the Expansion of Laboratories Funded by the National Institute of Allergy and Infectious Diseases

Correspondence issued by the Government Accountability Office with an abstract that begins "The fall 2001 anthrax attacks revealed gaps in the nation's preparedness for public health emergencies resulting from bioterrorism. Among the tools needed for responding to such emergencies are vaccines to prevent the spread of disease; tests for rapid diagnosis; and therapeutics, including drugs, for treatment. Because the pathogens that could be used in bioterrorist attacks carry the risk of significant morbidity or are potentially lethal, biological research aimed at providing the tools needed to combat these agents is required to be conducted in facilities known as biocontainment laboratories. These facilities are to be designed, constructed, and operated in a manner to prevent accidental release of infectious or hazardous agents within the laboratory and to protect laboratory workers and the environment external to the laboratory, including the community, from exposure to these research materials. The National Institute of Allergy and Infectious Diseases (NIAID) is the primary institute at the Department of Health and Human Services' (HHS) National Institutes of Health (NIH) that is responsible for research on pathogens that could be used in a bioterrorist attack and for research on emerging infectious disease pathogens.

Agricultural Conservation: State Advisory Committees' Views on How USDA Programs Could Better Address Environmental Concerns

A letter report issued by the General Accounting Office with an abstract that begins "Private landowners own more than two-thirds of the continental United States' 1.9 billion acres. Recognizing the critical role that private landowners play in managing soil, water, and wildlife habitat, Congress directed the U.S. Department of Agriculture (USDA) to improve stewardship practices on these lands. USDA currently has more than 70 million acres of privately-owned land enrolled in programs that offer landowners financial incentives to implement conservation practices to protect or improve soil and water quality and wildlife habitat. USDA's conservation efforts address specific environmental concerns, target funding toward state and local environmental priority areas, and promote partnerships with state or local entities to leverage limited funding. State technical committee members indicated that although USDA's conservation programs are generally effective, some targeted programs are more effective than others. Committee members cited several elements of the current programs that hinder achievement of environmental objectives and indicated a preference for more flexibility in new or existing programs. More than two-thirds of members considered program provisions that prohibit landowners from receiving compensation for maintaining previously implemented landowner-financed conservation practices to be a hindrance. Members would like to be able to …

Drinking Water: Revisions to EPA's Cost Analysis for the Radon Rule Would Improve Its Credibility and Usefulness

A letter report issued by the General Accounting Office with an abstract that begins "The Safe Drinking Water Act requires the Environmental Protection Agency (EPA) to set a drinking water standard for radon. In a proposed rule issued in November 1999, EPA presented a unique and complex drinking water regulation for radon. GAO found that EPA's analysis of the costs to implement the proposed radon rule has several strengths. EPA's estimates of the typical costs for water systems to buy and install radon removal technologies--a key determinant of total national costs--are reasonable for estimating national compliance costs. Moreover, EPA used recommendations from an expert panel to estimate the costs to install and maintain radon removal equipment. EPA also developed a range of annual cost estimates, rather than a single estimate, to account for uncertainty about the extent to which the less costly alternative standard will be adopted by states. EPA's analysis of the national annual costs to comply with its proposed radon drinking water rule has several limitations that, if corrected, would likely increase EPA's best estimate of these costs. EPA made two errors in estimating the various costs associated with programs to reduce radon levels in indoor air under …

Contract Management: Excess Payments and Underpayments Continue to Be a Problem at DOD

A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the amount of excess payments and underpayments made by the Department of Defense (DOD) to its contractors during fiscal year 1999. The Defense Finance and Accounting Service (DFAS)--Columbus Center, Ohio reports that contractors repaid $670 million in fiscal year 1999 and closer to a billion dollars--$901 million--in fiscal year 2000. The higher amount for fiscal year 2000 reflects the inclusion of repayments made through offsets of other payments ($269 million) in addition to the amount repaid by check ($632 million). Although small in relation to total contract payments, these amounts represent a sizable amount of cash in the hands of contractors beyond what is intended to finance and pay for the goods and services DOD is purchasing. The 39 large contractors covered by GAO's review returned excess payments totaling $351 million in fiscal year 1999. Seventy-seven percent of these excess payments stemmed from contract administration actions and 18 percent stemmed from billing or payment errors. Large contractors reported resolving $41 million in underpayments during fiscal year 1999. Contractors attributed most underpayments to payment errors made by DFAS--Columbus."

Information Resources Management: Comprehensive Strategic Plan Needed to Address Mounting Challenges (open access)

Information Resources Management: Comprehensive Strategic Plan Needed to Address Mounting Challenges

A letter report issued by the General Accounting Office with an abstract that begins "Congress passed the Paperwork Reduction Act (PRA) to establish a single, overarching policy framework for the management of government information resources. The act established information resources management (IRM) as an approach governing the collection, dissemination, security, privacy, and management of information. The act also created the Office of Information and Regulatory Affairs (OIRA) to provide leadership, policy direction, and oversight of governmentwide IRM. It further required OIRA to develop and maintain a governmentwide strategic IRM plan and charged that office with responsibilities for general IRM policy and information technology. Although OIRA designated the Chief Information Officers Council's strategic plan for fiscal years 2001-2002 as the governmentwide strategic IRM plan required by the PRA, this does not constitute an effective and comprehensive strategic vision. OIRA has issued policy and implementing guidance, conducted oversight activities, and taken various steps in each of the functional areas. GAO found that the documents cited by OMB during it's review did not, separately or collectively, meet the requirements for a governmentwide strategic IRM plan established by PRA."

A letter report issued by the Government Accountability Office with an abstract that begins "America's port infrastructure is vital to U.S. foreign trade and a bulwark for national security. One way the federal government funds port-related programs is to levy user fees. GAO was asked to examine (1) what is known about the way selected fees assessed on air and sea port users are set, collected, used, and reviewed and (2) the effects of these attributes on program operations. GAO examined the Harbor Maintenance Fee (HMF), the Merchandise Processing Fee (MPF), and the Customs, Immigration, and Agricultural Quarantine Inspection (AQI) user fees assessed on air and cruise passengers and commercial vessels using criteria that have often been used to assess user fees and taxes--equity, efficiency, revenue adequacy, and administrative burden."

The Third Image of the Large-Separation Lensed Quasar SDSS J1029+2623 (open access)

The Third Image of the Large-Separation Lensed Quasar SDSS J1029+2623

We identify a third image in the unique quasar lens SDSS J1029+2623, the second known quasar lens produced by a massive cluster of galaxies. The spectrum of the third image shows similar emission and absorption features, but has a redder continuum than the other two images which can be explained by differential extinction or microlensing. We also identify several lensed arcs. Our observations suggest a complicated structure of the lens cluster at z {approx} 0.6. We argue that the three lensed images are produced by a naked cusp on the basis of successful mass models, the distribution of cluster member galaxies, and the shapes and locations of the lensed arcs. Lensing by a naked cusp is quite rare among galaxy-scale lenses but is predicted to be common among large-separation lensed quasars. Thus the discovery can be viewed as support for an important theoretical prediction of the standard cold dark matter model.

Sum Frequency Generation Vibrational Spectroscopy of Pyridine Hydrogenation on Platinum Nanoparticles (open access)

Sum Frequency Generation Vibrational Spectroscopy of Pyridine Hydrogenation on Platinum Nanoparticles

Pyridine hydrogenation in the presence of a surface monolayer consisting of cubic Pt nanoparticles stabilized by tetradecyltrimethylammonium bromide (TTAB) was investigated by sum frequency generation (SFG) vibrational spectroscopy using total internal reflection (TIR) geometry. TIR-SFG spectra analysis revealed that a pyridinium cation (C{sub 5}H{sub 5}NH{sup +}) forms during pyridine hydrogenation on the Pt nanoparticle surface, and the NH group in the C{sub 5}H{sub 5}NH{sup +} cation becomes more hydrogen bound with the increase of the temperature. In addition, the surface coverage of the cation decreases with the increase of the temperature. An important contribution of this study is the in situ identification of reaction intermediates adsorbed on the Pt nanoparticle monolayer during pyridine hydrogenation.

FILL STEM MANUFACTURING CHANGES AND PINCH WELD QUALIFICATIONS (open access)

FILL STEM MANUFACTURING CHANGES AND PINCH WELD QUALIFICATIONS

In March of 2007 a document was issued, see attachment I, that defined the test protocol and required welding for the Kansas City Plant to change cutting oils from the recently approved 50:50 oil to an oil with similar characteristics but with different chemistry, additives, and possibly a different vendor due to plans by the current vendor to stop preparing the oils that are used in the KCP 50:50 mix. The KCP manufactured stems with the existing 50:50 oil blend in late FY07 and SRNL welded the stems and evaluated them in agreement with the test plan. This report provides all the data from these set-up and test welds. Set-up welds were shot and low and high voltages (currents) to ensure the window limits were applicable and then additional welds were made to validate the window. The purpose of this report is to ensure that the agreed upon path forward is still applicable.
