Testimony issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) contains EPA's scientific position on the potential human health effects of exposure to more than 540 chemicals. Toxicity assessments in the IRIS database constitute the first two critical steps of the risk assessment process, which in turn, provides the foundation for risk management decisions. Thus, IRIS is a critical component of EPA's capacity to support scientifically sound environmental decisions, policies, and regulations. This testimony discusses (1) highlights of GAO's March 2008 report, Chemical Assessments: Low Productivity and New Interagency Review Process Limit the Usefulness and Credibility of EPA's Integrated Risk Information System, and (2) key aspects of EPA's revised IRIS assessment process, released on April 10, 2008. For the March 2008 report, GAO reviewed and analyzed EPA data and interviewed officials at relevant agencies, including the Office of Management and Budget (OMB). For this testimony, GAO supplemented the prior audit work with a review of EPA's revised IRIS assessment process announced on April 10, 2008."

A letter report issued by the Government Accountability Office with an abstract that begins "Department of Defense (DOD) officials who serve in senior and acquisition positions and then leave for jobs with defense contractors are subject to the restrictions of post-government employment laws, in order to protect against conflicts of interest. Congress required GAO to report on employment of such officials by contractors who received more than $500 million in DOD's 2005 contract awards. In response, this report (1) provides information on how many former DOD employees worked for contractors in 2006 and estimates how many worked on contracts that were related to their former agencies or to their direct responsibilities and (2) identifies the practices used to monitor restrictions and information challenges in monitoring post-DOD employment. To do this work, GAO matched data from DOD for all employees who left DOD over a 6 year period with data from the Internal Revenue Service (IRS) and from 52 contractors; conducted surveys; and interviewed DOD and contractor officials."

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) was created from a disparate group of agencies with multiple missions, values, and cultures into a cabinet department whose goals are to, among other things, protect U.S. borders and infrastructure, improve intelligence and information sharing, and prevent and respond to potential terrorist attacks. GAO designated the implementation and transformation of DHS as a high-risk area in 2003, and it remains so. While DHS has made progress, it continues to face challenges in transforming into an effective, integrated organization. In response to a request to provide information on diversity in DHS and steps DHS is taking to create and manage a diverse workforce, GAO is providing demographic data related to the federal government as a whole and DHS's workforce. GAO obtained these data from the Office of Personnel Management's (OPM) Central Personnel Data File (CPDF). GAO used its past work on leading diversity management practices (GAO-05-90) and reviewed data from DHS on its diversity management practices."

A letter report issued by the Government Accountability Office with an abstract that begins "Securing the control systems that regulate the nation's critical infrastructures is vital to ensuring our economic security and public health and safety. The Tennessee Valley Authority (TVA), a federal corporation and the nation's largest public power company, generates and distributes power in an area of about 80,000 square miles in the southeastern United States. GAO was asked to determine whether TVA has implemented appropriate information security practices to protect its control systems. To do this, GAO examined the security practices in place at several TVA facilities; analyzed the agency's information security policies, plans, and procedures against federal law and guidance; and interviewed agency officials who are responsible for overseeing TVA's control systems and their security."

Testimony issued by the Government Accountability Office with an abstract that begins "The control systems that regulate the nation's critical infrastructures face risks of cyber threats, system vulnerabilities, and potential attacks. Securing these systems is therefore vital to ensuring national security, economic well-being, and public health and safety. While most critical infrastructures are privately owned, the Tennessee Valley Authority (TVA), a federal corporation and the nation's largest public power company, provides power and other services to a large swath of the American Southeast. GAO was asked to testify on its public report being released today on the security controls in place over TVA's critical infrastructure control systems. In doing this work, GAO examined the security practices in place at TVA facilities; analyzed the agency's information security policies, plans, and procedures in light of federal law and guidance; and interviewed agency officials responsible for overseeing TVA's control systems and their security."

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of the Interior's (Interior) U.S. Fish and Wildlife Service (Service) is generally required to use the best available scientific information when making key decisions under the Endangered Species Act (ESA). Controversy has surrounded whether former Deputy Assistant Secretary Julie MacDonald may have inappropriately influenced ESA decisions by basing decisions on political factors rather than scientific data. Interior directed the Service to review ESA decisions to determine which decisions may have been unduly influenced. ESA actions include, among others, 90-day petition findings, 12-month listing or delisting findings, and recovery planning. The Service distributed informal guidance in May 2005 on the processing of 90-day petitions. Recovery plans generally must include recovery criteria that, when met, would result in the species being delisted. GAO examined three separate issues: (1) what types of decisions, if any, were excluded from the Service's review of decisions that may have been inappropriately influenced; (2) to what extent the Service's May 2005 informal guidance affected 90-day petition findings; and (3) to what extent the Service has, before delisting species, met recovery criteria. GAO interviewed Service staff, surveyed Service biologists, and reviewed delisting rules and …
