Testimony issued by the Government Accountability Office with an abstract that begins "The opportunity for employment is one of the most important magnets attracting illegal immigrants to the United States. The Immigration Reform and Control Act (IRCA) of 1986 established an employment eligibility verification process and a sanctions program for fining employers for noncompliance. Few modifications have been made to the verification process and sanctions program since 1986, and immigration experts state that a more reliable verification process and a strengthened worksite enforcement capacity are needed to help deter illegal immigration. This testimony is based on GAO's August 2005 report on the employment verification process and worksite enforcement efforts. In this testimony, GAO provides observations on (1) the current employment verification process and (2) U.S. Immigration and Customs Enforcement's (ICE) priorities and resources for the worksite enforcement program and the challenges it faces in implementing that program."

Testimony issued by the Government Accountability Office with an abstract that begins "Scientific evidence links exposure to particulate matter--a widespread form of air pollution--to serious health problems, including asthma and premature death. Under the Clean Air Act, the Environmental Protection Agency (EPA) periodically reviews the appropriate air quality level at which to set national standards to protect the public against the health effects of six pollutants, including particulate matter. EPA proposed revisions to the particulate matter standards in January 2006 and issued a regulatory impact analysis of the revisions' expected costs and benefits. The estimated benefits of air pollution regulations have been controversial in the past, and a 2002 National Academies report to EPA made recommendations aimed at improving the estimates for particulate matter and other air pollution regulations. This testimony is based on GAO's July 2006 report Particulate Matter: EPA Has Started to Address the National Academies' Recommendations on Estimating Health Benefits, but More Progress Is Needed (GAO-06-780). GAO determined whether and how EPA applied the National Academies' recommendations in its estimates of the health benefits expected from the January 2006 proposed revisions to the particulate matter standards."

Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. rail transit system is a vital component of the nation's transportation infrastructure, carrying millions of people daily. Unlike most transportation modes, safety and security oversight of rail transit is the responsibility of state-designated oversight agencies following Federal Transit Administration (FTA) requirements. In addition, in 2001, Congress passed the Aviation and Transportation Security Act, giving the Transportation Security Administration (TSA) authority for security over all transportation modes, including rail transit. This testimony is based on ongoing work for this subcommittee's committee--the House Committee on Transportation and Infrastructure. I describe (1) how the State Safety Oversight program is designed; (2) what is known about the impact of the program on rail safety and security; and (3) challenges facing the program. I also provide information about oversight of transit systems that cross state boundaries. To address these issues, we reviewed program documents and interviewed stakeholders including officials from FTA, TSA, the National Transportation Safety Board, and the American Public Transportation Association. We also surveyed state oversight and transit agencies covered by FTA's program, interviewing 24 of the 25 oversight agencies and 37 of 42 transit agencies across the country."

Testimony issued by the Government Accountability Office with an abstract that begins "The Nuclear Regulatory Commission (NRC) has the responsibility to provide oversight to ensure that the nation's 103 commercial nuclear power plants are operated safely. While the safety of these plants has always been important, since radioactive release could harm the public and the environment, NRC's oversight has become even more critical as the Congress and the nation consider the potential resurgence of nuclear power in helping to meet the nation's growing energy needs. Prior to 2000, NRC was criticized for having a safety oversight process that was not always focused on the most important safety issues and in some cases, was overly subjective. To address these and other concerns, NRC implemented a new oversight process--the Reactor Oversight Process (ROP). NRC continues to modify the ROP to incorporate feedback from stakeholders and in response to other external events. This testimony summarizes information on (1) how NRC oversees nuclear power plants, (2) the results of the ROP over the past several years, and (3) the aspects of the ROP that need improvement and the status of NRC's efforts to improve them. This testimony discusses preliminary results of GAO's work. GAO …

Testimony issued by the Government Accountability Office with an abstract that begins "In the wake of the 2005 hurricanes in the Gulf Region, GAO and the Department of Homeland Security Office of Inspector General (DHS OIG) initiated a number of audits and investigations addressing the federal government's response to those events. Department of Homeland Security (DHS) cardholders made thousands of transactions related to hurricane rescue and relief operations. GAO, working with DHS OIG, interviewed DHS personnel and reviewed purchase card policies and procedures to assess the control environment. GAO and DHS OIG conducted statistical tests from a random sample of transactions and performed data mining on all DHS purchase card transactions for a 5-month period beginning in June 2005. GAO and DHS OIG looked at all transactions in this period because the database did not distinguish hurricane related from routine purchases. GAO and DHS OIG used the testing results to determine the extent of control weaknesses and identify instances of fraud, waste, and abuse. This testimony addresses whether (1) DHS's control environment and management of purchase card usage were effective; (2) DHS's key internal control activities operated effectively and provided reasonable assurance that purchase cards were used appropriately; and (3) …

Correspondence issued by the Government Accountability Office with an abstract that begins "The Air Force plans to construct 233 military housing units on Spangdahlem Air Base, Germany at a cost of $131.3 million spread over fiscal years 2006-2008, and to fund 270 build-to-lease units nearby at an annual cost of $32,888 per unit over 20 years. The Military Quality of Life and Veterans Affairs Appropriations Act for fiscal year 2006 directed the Secretary of the Air Force to submit to the Committees on Appropriations of both Houses of Congress a report containing a housing plan for Spangdahlem. The House Conference Report accompanying H.R. 2528 stipulated that the report must include a complete cost-benefit analysis of available housing options to include build-to-lease housing, and that none of the funds appropriated for family housing at Spangdahlem--nearly $45.4 million--may be obligated until the Secretary of the Air Force certified to the Appropriations Committees that the report had been completed and received the Committees' response or a 30-day period has elapsed after the Committees receive such report. In response to the mandate, the Air Force issued a report in January 2006 that compared its proposed plan with four other housing options that included a …

Correspondence issued by the Government Accountability Office with an abstract that begins "In fiscal year 2005, prime vendor sales accounted for approximately $9 billion of the Defense Logistics Agency's (DLA) total sales and service of $32 billion. Under the prime vendor concept, the Department of Defense (DOD) relies on a distributor of a commercial product line, who provides that product line and incidental services to customers in an assigned region or area of responsibility. Products or services are to be delivered within a specified period of time after order placement. Since 1991, we have identified the use of prime vendors as a best commercial practice for inventory management. Nonetheless, media reports in October 2005, and a hearing before the House Armed Services Committee on November 9, 2005, raised concerns about the use of the prime vendor concept and the prices that DLA was paying for items acquired through a prime vendor. The use of prime vendor contracts is governed by the Federal Acquisition Regulation (FAR) and the Defense Federal Acquisition Regulation Supplement. DLA manages the program and the Director of DLA reports to the Under Secretary of Defense for Acquisition, Technology and Logistics through the Deputy Under Secretary of Defense …
