A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Aviation Administration (FAA) performs critical functions that contribute to ensuring safe, orderly, and efficient air travel in the national airspace system. To that end, it operates and relies extensively on an array of interconnected automated information systems and networks that comprise the nation's air traffic control systems. These systems provide information to air traffic controllers and aircraft flight crews to help ensure the safe and expeditious movement of aircraft. Interruptions of service by these systems could have a significant adverse impact on air traffic nationwide. Effective information security controls are essential for ensuring that the nation's air traffic control systems are adequately protected from inadvertent or deliberate misuse, disruption, or destruction. Accordingly, GAO was asked to evaluate the extent to which FAA has implemented information security controls for these systems."

Correspondence issued by the General Accounting Office with an abstract that begins "Earlier this year, GAO initiated a governmentwide review of the implementation of the Federal Civil Penalties Inflation Adjustment Act of 1990. The Inflation Adjustment Act requires each federal agency to issue a regulation adjusting its covered maximum and minimum civil monetary penalties for inflation by October 23, 1996, and requires them to make necessary adjustments at least once every 4 years thereafter. During the review, the Department of Education's Office of the General Counsel indicated that at least eight of the agency's civil penalties are covered by that act, but the agency had not yet adjusted any of them for inflation."

A letter report issued by the Government Accountability Office with an abstract that begins "NASA's Constellation program is developing the Ares I Crew Launch Vehicle and the Orion Crew Exploration Vehicle as the agency's first major efforts in a plan to return to the moon and eventually send humans to Mars. GAO has issued a number of reports and testimonies on various aspects of this program, and made several recommendations. GAO was asked to assess NASA's progress in implementing GAO's recommendations for the Ares I and Orion projects, and identify risks the program faces. GAO analyzed NASA plans and schedules, risk mitigation information, and contract performance data relative to knowledge-based acquisition practices identified in prior GAO reports, and interviewed government officials and contractors."

A letter report issued by the Government Accountability Office with an abstract that begins "Since its creation, the National Aeronautics and Space Administration (NASA) has operated passenger aircraft services. These operations have been questioned in several prior audit reports. GAO was asked to perform a series of audits of NASA's controls to prevent fraud, waste, and abuse of taxpayer dollars. In this audit, GAO assessed (1) the relative cost of NASA passenger aircraft services in comparison with commercial costs, (2) whether NASA aircraft services were retained and operated in accordance with governmentwide guidance, and (3) the effectiveness of NASA's oversight and management of this program."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2005, Americans will pay about $2.1 trillion in combined federal taxes, including income, payroll, and excise taxes, or about 16.8 percent of Gross Domestic Product (GDP). However, the amount of taxes paid does not reflect the total cost to taxpayers of the federal tax system. In addition to taxes paid, taxpayers also bear compliance costs and efficiency costs. Understanding the magnitude of these additional costs is important because every dollar spent on compliance and lost due to inefficiency represents a dollar that society could have spent for other purposes. In response to a congressional request for information on the magnitude of the compliance and efficiency costs of the current federal tax system, this study describes the nature of these costs, presents the difficulties associated with estimating them, and summarizes existing estimates of their magnitude. GAO did not make independent estimates of compliance or efficiency costs nor did we replicate any of the studies. GAO is not making any recommendations in this report."

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 …
