Correspondence issued by the Government Accountability Office with an abstract that begins "The alleged August 2006 terrorist plot to detonate liquid explosives onboard multiple commercial aircraft bound for the United States from the United Kingdom has highlighted both the continued importance of securing the civil aviation system and the potential that improvised explosive devices (IED) may be smuggled onboard passenger aircraft. The Transportation Security Administration (TSA) has primary responsibility for ensuring the security of civil aviation, which includes the safety of passengers and flight crew. One measure TSA uses to protect the aviation system is prohibiting individuals from carrying items that it determines to be a threat to the aircraft and its passengers into an airport sterile area or onboard an aircraft either in their carry-on bag or on their person. To implement this measure, TSA maintains a prohibited items list that informs both the Transportation Security Officers (TSO) who conduct passenger screening and the traveling public of items that will not be allowed into an airport sterile area or onboard an aircraft. In December 2005, TSA revised its prohibited items list to allow passengers to carry: (1) metal scissors with pointed tips and a blade 4 inches or less …

Testimony issued by the Government Accountability Office with an abstract that begins "Congress established two key programs to help support air service to small communities--the Essential Air Service (EAS) providing about $100 million in subsidies per year and the Small Community Air Service Development Program (SCASDP) that provides about $20 million per year in grants. As part of its reauthorization of the Federal Aviation Administration (FAA), the Congress is examining the status and outcomes of these programs. This testimony discusses (1) the history and challenges of the EAS program, (2) the implementation and outcomes of the SCASDP and (3) options for reforming EAS and SCASDP. The testimony is based on previous GAO reports, interviews with Department of Transportation officials and industry representatives as well as program updates."

Testimony issued by the Government Accountability Office with an abstract that begins "In testimony before this committee and the House Committee on Appropriations, Subcommittee on Homeland Security in February 2007, GAO stated that the Department of Homeland Security (DHS) has not made its management or operational decisions transparent enough to allow Congress to be sure that the Department is effectively, efficiently, and economically using its billions of dollars of annual funding. GAO also noted that its work for Congress to assess DHS's operations has, at times, been significantly hampered by long delays in obtaining access to program documents. Following the aforementioned testimonies, GAO was asked to testify about its access issues. This testimony provides information on (1) the scope of GAO's work, (2) GAO protocols for accessing agency information, (3) DHS processes for working with GAO, (4) access issues GAO has encountered, and (5) steps GAO has taken to address these issues."

Testimony issued by the Government Accountability Office with an abstract that begins "Perchlorate has been used for decades by the Department of Defense, the National Aeronautics and Space Administration, and the defense industry in manufacturing, testing, and firing missiles and rockets. Other uses include fireworks, fertilizers, and explosives. Perchlorate is readily dissolved and transported in water and has been found in groundwater, surface water, and soil across the country. Perchlorate emerged as a contaminant of concern because health studies have shown that it can affect the thyroid gland, which helps regulate the body's metabolism, and may cause developmental impairment in fetuses of pregnant women. In 2005, EPA set a reference dose of 24.5 parts per billion (ppb)--the exposure level not expected to cause adverse effect in humans. Today's testimony updates GAO's May 2005 report, Perchlorate: A System to Track Sampling and Cleanup Results is Needed, GAO-05-462. It summarizes GAO's (1) compilation of the extent of perchlorate contamination in the U.S. and (2) review of peer-reviewed studies about perchlorate's health risks. GAO's 2005 report recommended that EPA work to track and monitor perchlorate detections and cleanup efforts. In December 2006, EPA reiterated its disagreement with this recommendation. GAO continues to believe …
