Correspondence issued by the Government Accountability Office with an abstract that begins "In October 2007, we reported on how the Environmental Protection Agency (EPA) and other federal agencies had assessed and addressed risks at sites that were thought to have received asbestos-contaminated ore from a mine located in Libby, Montana, and the overall results of these efforts. As we noted at that time, EPA has identified hundreds of sites nationwide that are thought to have received millions of tons of the contaminated ore between 1923 and the early 1990s. This report provides information that will be helpful in understanding the site descriptions in the database, which is provided in a separate report, entitled Hazardous Materials: EPA's Assessment of Sites That May Have Received Asbestos- Contaminated Ore from Libby, Montana (GAO-09-7SP)."

Testimony issued by the Government Accountability Office with an abstract that begins "Pervasive and sustained computerbased (cyber) attacks against federal and private-sector infrastructures pose a potentially devastating impact to systems and operations and the critical infrastructures that they support. To address these threats, President Bush issued a 2003 national strategy and related policy directives aimed at improving cybersecurity nationwide. Congress and the Executive Branch, including the new administration, have subsequently taken actions to examine the adequacy of the strategy and identify areas for improvement. Nevertheless, GAO has identified this area as high risk and has reported on needed improvements in implementing the national cybersecurity strategy. In this testimony, you asked GAO to summarize (1) key reports and recommendations on the national cybersecurity strategy and (2) the views of experts on how to strengthen the strategy. In doing so, GAO relied on its previous reports related to the strategy and conducted panel discussions with key cybersecurity experts to solicit their views on areas for improvement."

Testimony issued by the Government Accountability Office with an abstract that begins "A safe, efficient, and convenient transportation system is integral to the health of our economy and quality of life. Our nation's vast transportation system of airways, railways, roads, transit systems, and waterways has served this need, yet is under considerable pressure due to increasing congestion and costs to maintain and improve the system. Calls for increased investment come at a time when traditional funding for transportation projects is increasingly strained. The authorizing legislation supporting transportation programs will soon expire. The Department of Transportation (DOT) implements national transportation policy and administers most federal transportation programs. DOT received funds for transportation infrastructure projects through the American Recovery and Reinvestment Act of 2009 to aid in economic recovery. DOT also requested $72.5 billion to carry out its activities for fiscal year 2010. This statement presents GAO's views on major challenges facing DOT and Congress as they work to administer recovery funds and reauthorize surface transportation and aviation programs. It is based on work GAO has completed over the last several years. GAO has made recommendations to DOT to improve transportation programs; the agency has generally agreed with these recommendations.
