Testimony issued by the Government Accountability Office with an abstract that begins "In preparing for the 2020 Census, the U.S. Census Bureau (Bureau) has launched several initiatives aimed at organizational transformation, some of which show particular promise. For example, the Bureau is attempting to develop Bureau-wide, or "enterprise," standards, guidance, or tools in areas such as risk management and information technology (IT) investment management to reduce duplicative efforts across the Bureau. Although the Bureau has made progress in these and other areas, if the Bureau is to transform itself to better control costs and deliver an accurate national headcount in 2020, several areas will require continued oversight: cost estimation, integrated long-term planning, and stakeholder involvement. For example, while the Bureau has made progress with long-term planning by implementing some elements of GAO's recommendation that it develop a road map for 2020 planning, it still needs to pull together remaining planning elements, such as milestones for decisions and estimates of cost, into its roadmap."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Nuclear Security Administration's (NNSA) Los Alamos National Laboratory's (LANL) April 2012 study (1) identified general options for meeting the plutonium research needs of NNSA--a separately organized agency within the Department of Energy (DOE)--during the several-year gap created by the deferral of the Chemistry and Metallurgy Research Replacement (CMRR) nuclear facility and (2) included limited information on costs and health risks. The study noted that the level of plutonium research necessary to support the nuclear weapons life extension programs is affected by the planned schedule of the life extension programs, the number of pits that will be needed under the programs, and the number of pits that will need to be manufactured versus re-used, all of which have uncertainties. According to the April 2012 study, one option for meeting NNSA's plutonium research needs is to relocate analytical chemistry and materials characterization capabilities among facilities at LANL, which will require upgrades costing roughly $480 million to $820 million. A second option is to move capabilities to existing facilities at other sites. The study concluded that no single site could provide all the capabilities that might be …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration's (PHMSA) incident data cannot be used to reliably identify risks from incidents involving collisions with and spills from tank trucks' bottom lines ("wetlines") because the incidents are not specifically identified in PHMSA's database and the data contain inaccuracies. PHMSA requires carriers to report hazardous material incidents, but the reporting form does not specifically capture wetline incidents. PHMSA officials identify wetline incidents through a resource-intensive process of reviewing carrier-reported incident narratives and other information. However, GAO found that the narratives do not always clearly indicate whether an incident is wetline related and that information about the consequences of incidents, including fatalities, is not always accurate. PHMSA has made efforts to improve its data, such as adding quality checks, but this has not affected how wetline incidents are reported, and inaccuracies remain."

Testimony issued by the Government Accountability Office with an abstract that begins "GAO's work has shown that the Department of Homeland Security (DHS), through its component agencies, particularly the Coast Guard and U.S. Customs and Border Protection (CBP), have made substantial progress in implementing various programs that, collectively, have improved maritime security. In general, GAO's work on maritime security programs falls under four areas: (1) security planning, (2) port facility and vessel security, (3) maritime domain awareness and information sharing, and (4) international supply chain security. DHS has, among other things, developed various maritime security programs and strategies and has implemented and exercised security plans. For example, the Coast Guard has developed Area Maritime Security Plans around the country to identify and coordinate Coast Guard procedures related to prevention, protection, and security response at domestic ports. In addition, to enhance the security of U.S. ports, the Coast Guard has implemented programs to conduct annual inspections of port facilities. To enhance the security of vessels, both CBP and the Coast Guard receive and screen advance information on commercial vessels and their crews before they arrive at U.S. ports and prepare risk assessments based on this information. Further, DHS and its component …

A letter report issued by the Government Accountability Office with an abstract that begins "Using several methods of varying precision, mobile industry companies collect location data and use or share that data to provide users with location-based services, offer improved services, and increase revenue through targeted advertising. Location-based services provide consumers access to applications such as real-time navigation aids, access to free or reduced-cost mobile applications, and faster response from emergency services, among other potential benefits. However, the collection and sharing of location data also pose privacy risks. Specifically, privacy advocates said that consumers: (1) are generally unaware of how their location data are shared with and used by third parties; (2) could be subject to increased surveillance when location data are shared with law enforcement; and (3) could be at higher risk of identity theft or threats to personal safety when companies retain location data for long periods or share data with third parties that do not adequately protect them."

Testimony issued by the Government Accountability Office with an abstract that begins "The termination of the six defined benefit plans that were sponsored by the Delphi Corporation (Delphi) and the provision of benefit protections to some Delphi employees, but not others, culminated from a complex series of events involving Delphi, the General Motors Corporation (GM), various unions, the U.S. Department of the Treasury (Treasury), and the Pension Benefit Guaranty Corporation (PBGC). When Delphi spun off from GM in 1999, three unions secured an agreement that GM would provide a retirement benefit supplement (referred to as "top-ups") for their members should their pension plans be frozen or terminated and they were to suffer a resulting loss in pension benefits. These three unions were: (1) the International Union, United Automobile, Aerospace, and Agricultural Implement Workers of America (UAW); (2) the International Union of Electronic, Electrical, Salaried, Machine and Furniture Workers, AFL-CIO (IUE); and (3) the United Steelworkers of America (USWA). No other Delphi employees had a similar agreement to receive a top-up, including salaried workers and hourly workers belonging to other unions. Over the course of events that unfolded over the next decade, the agreements with these three unions ultimately were preserved …

Testimony issued by the Government Accountability Office with an abstract that begins "The November 2011 memorandum that discussed the management of the Chemical Facility Anti-Terrorism Standards (CFATS) program was prepared based primarily on the observations of the former Director of the Department of Homeland Security’s (DHS) Infrastructure Security Compliance Division (ISCD), a division of the Office of Infrastructure Protection (IP) within the National Protection and Programs Directorate (NPPD). The memorandum was intended to highlight various challenges that have hindered ISCD efforts to implement the CFATS program. According to the former Director, the challenges facing ISCD included not having a fully developed direction and plan for implementing the program, hiring staff without establishing need, and inconsistent ISCD leadership—factors that the Director believed place the CFATS program at risk. These challenges centered on three main areas: (1) human capital issues, including problems hiring, training, and managing ISCD staff; (2) mission issues, including problems reviewing facility plans to mitigate security vulnerabilities; and (3) administrative issues, including concerns about NPPD and IP not supporting ISCD’s management and administrative functions."

Testimony issued by the Government Accountability Office with an abstract that begins "The Transportation Security Administration (TSA) has taken actions to validate the science underlying its behavior-based passenger screening program, the Screening of Passengers by Observation Techniques, or SPOT, program, but more work remains. GAO reported in May 2010 that (1) TSA deployed SPOT before first determining whether there was a scientifically valid basis for using behavior and appearance indicators to reliably identify passengers who may pose a risk; and (2) it is unknown if the SPOT program has ever resulted in the arrest of anyone who is a terrorist, or who was planning to engage in terrorist related activity, although there is other evidence that terrorists have transited through SPOT airports. GAO recommended in May 2010 that the Department of Homeland Security (DHS) convene an independent panel of experts to review the methodology of the ongoing validation study on the SPOT program to determine whether it is sufficiently comprehensive to validate the program. DHS concurred and subsequently revised its validation study to include an independent expert review. DHS's study, completed in April 2011, found that SPOT was more effective than random screening to varying degrees; however, DHS noted limitations …

Testimony issued by the Government Accountability Office with an abstract that begins "As GAO reported in September 2012, nine selected states had made varying degrees of progress in modernizing the information technology (IT) systems supporting their unemployment insurance (UI) programs. Specifically, the states' modernization efforts were at various stages--three were in early phases of defining business needs and requirements, two were in the process of building systems based on identified requirements, two were in a "mixed" phase of having a system that was partly operational and partly in development, and two had systems that were completely operational. The enhancements provided by these systems included supporting web-based technologies with more modern databases and replacing outdated programming languages, among others."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Oceanic and Atmospheric Administration (NOAA) has made noteworthy progress on the Joint Polar Satellite System (JPSS) program by delivering data from its first satellite--the Suomi National Polar-orbiting Partnership (S-NPP)--to weather forecasters, completing significant instrument development for the next satellite (called JPSS-1), and reducing the program's life cycle cost estimate from $12.9 billion to $11.3 billion by refocusing on weather products. However, key challenges remain. Specifically, S-NPP has not yet achieved full operational capability because the program is behind schedule in validating the readiness of satellite products. Also, the program does not track whether key users are using its products or if the products meet the users' needs. In addition, issues with the JPSS ground system schedules have delayed the delivery of key system capabilities. Until the program addresses these challenges, it may continue to experience delays in delivering actionable S-NPP data to system users and in meeting JPSS-1 development schedules."

A letter report issued by the Government Accountability Office with an abstract that begins "These new organizations--the Financial Stability Oversight Council (FSOC) and Office of Financial Research (OFR)--face challenges in achieving their missions. Key FSOC missions--to identify risks and respond to emerging threats to financial stability--are inherently challenging, in part, because risks to financial stability do not develop in precisely the same way in successive crises. Collaboration among FSOC members can also be challenging at times, as almost all of them represent independent agencies that retained existing authorities. OFR faces the challenge of trying to establish and build a world-class research organization while meeting shorter-term goals and responsibilities."

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Department of Agriculture's (USDA) Farm Service Agency (FSA) and the Small Business Administration (SBA) have 10 disaster assistance programs that small agricultural producers and businesses that support agriculture can use to recover from natural disasters. These programs serve largely different populations but leave few gaps in the disaster assistance available to most small agricultural producers. Aquaculture and nursery producers could be eligible for six of these programs, but their participation is limited by awareness and eligibility issues."

This report discusses, in broad terms, disaster-related tax policy. Challenges associated with using the tax code to deliver federal financial assistance following natural disasters are also discussed.

Detecting and predicting maneuvering satellites is an important problem for Space Situational Awareness. The spatial envelope of all possible locations within reach of such a maneuvering satellite is known as the Reachable Volume (RV). As soon as custody of a satellite is lost, calculating the RV and its subsequent time evolution is a critical component in the rapid recovery of the satellite. In this paper, we present a Monte Carlo approach to computing the RV for a given object. Essentially, our approach samples all possible trajectories by randomizing thrust-vectors, thrust magnitudes and time of burn. At any given instance, the distribution of the 'point-cloud' of the virtual particles defines the RV. For short orbital time-scales, the temporal evolution of the point-cloud can result in complex, multi-reentrant manifolds. Visualization plays an important role in gaining insight and understanding into this complex and evolving manifold. In the second part of this paper, we focus on how to effectively visualize the large number of virtual trajectories and the computed RV. We present a real-time out-of-core rendering technique for visualizing the large number of virtual trajectories. We also examine different techniques for visualizing the computed volume of probability density distribution, including volume slicing, convex …

This attachment expands on the general description of the Nevada National Security Site (NNSS) presented in the Introduction to the Nevada National Security Site Environmental Report 2012 (National Security Technologies, LLC [NSTec], 2013). Included are subsections that summarize the site’s geological, hydrological, climatological, and ecological setting and the cultural resources of the NNSS. The subsections are meant to aid the reader in understanding the complex physical and biological environment of the NNSS. An adequate knowledge of the site’s environment is necessary to assess the environmental impacts of new projects, design and implement environmental monitoring activities for current site operations, and assess the impacts of site operations on the public residing in the vicinity of the NNSS. The NNSS environment contributes to several key features of the site that afford protection to the inhabitants of adjacent areas from potential exposure to radioactivity or other contaminants resulting from NNSS operations. These key features include the general remote location of the NNSS, restricted access, extended wind transport times, the great depths to slow-moving groundwater, little or no surface water, and low population density. This attachment complements the annual summary of monitoring program activities and dose assessments presented in the main body of this …
