U.S. Army's Procurements of Battle Effects Simulators

Correspondence issued by the General Accounting Office with an abstract that begins "The Army uses battle effects simulators on training ranges to help prepare its soldiers for realistic combat conditions. The simulators fire pyrotechnic cartridges that simulate the sound, smoke, and flash of shells being fired from or striking targets, such as armored vehicles. Concerns have been raised about the safety of the simulators now being used by the Army and the possibility that U.S. companies may be excluded from full and open competition for new simulators. The Army's existing battle effects simulators have experienced more than 120 documented malfunctions, many of which caused serious injuries, such as third-degree burns, loss of appendages, and lacerations. The Army has tried to make the devices safer and has suspended their use many times. It is also assessing the safety and the effectiveness of a new system from a foreign source. However, it does not plan to assess a U.S. system due to funding limitations. The Army could rely on the Marine Corps' planned type classification of a U.S. produced device to certify another qualified source for future competition."

Follow-up to the May 8, 2001, Hearing Regarding the IRS Restructuring Act's Goals and IRS Funding

Correspondence issued by the General Accounting Office with an abstract that begins "This report discusses (1) whether the goals of the Internal Revenue Service (IRS) Restructuring Act's goals are realistic and (2) disagreements between the IRS Oversight Board, the Treasury Inspector General for Tax Administration (TIGTA), and GAO on the act's funding issues. GAO found that the act's goals of meeting taxpayers' needs while ensuring compliance with the tax laws require a massive modernization of IRS. These changes involve major management challenges and will require considerable time to implement. Although IRS officials believe that they have complied with the act's requirements, they are still learning how to effectively manage in the new environment. GAO believes that it is premature to consider significant changes to the act. Differences exist among the Oversight Board, TIGTA, and GAO with respect to specific IRS funding issues."

Electronic Commerce: Small Business Participation in Selected On-line Procurement Programs

A letter report issued by the General Accounting Office with an abstract that begins "The federal government has been pursuing electronic initiatives to strengthen its buying processes, reduce costs, and create a competitive "virtual" marketplace. Small businesses, however, may have difficulty participating in federal on-line procurement programs. Furthermore, the government's business outreach and education programs related to electronic commerce may not be adequately coordinated. For the three federal on-line procurement programs GAO reviewed, the dollar share of awards to small businesses exceeded the overall small business share of total federal contract dollars awarded in fiscal years 2000 and 1999. Although small businesses successfully participated in these three programs, they still face obstacles in conducting electronic procurements with the government. The federal government is taking steps to address some of these obstacles, such as implementing a single point of entry on the Internet for vendors to access information on available government business opportunities greater than $25,000. Each of the four business assistance programs GAO examined had taken steps to educate its clients on electronic commerce as part of its operations. However, GAO could not fully determine the extent of these activities because they are conducted by hundreds of local and regional …

Environmental Protection: Grants Awarded for Continuing Environmental Programs and Projects

Correspondence issued by the General Accounting Office with an abstract that begins "This report reviews the Environmental Protection Agency's (EPA) administration of grants for environmental programs and projects. GAO focuses on the (1) total dollar amounts by type of grants awarded, (2) type of entities receiving these grants, (3) EPA offices awarding grants, and (4) congressional and other concerns raised by EPA grant activities. GAO found that EPA awarded about $16.7 billion in grants for fiscal years 1996 through 2000. States were the major recipients of continuing environmental program funds, while nonprofit organizations were the major recipients of project grants. EPA's Office of Water awarded half of all continuing environmental program grants, while the Offices of Solid Waste and Emergency Response, Research and Development, and Water awarded most project grants. Congressional committees and EPA's Inspector General conducted several inquiries into EPA's management of grants."

California Electricity Market: Outlook for Summer 2001

Correspondence issued by the General Accounting Office with an abstract that begins "As the electricity industry restructures, California and the west have witnessed extraordinarily high wholesale prices and sharp limitations on the availability of electricity. In California, high prices have led to financial problems for the state's utilities, power outages, and rate increases. In other Western states, the high prices have also led to rate increases for consumers. This report assesses the outlook for California's electricity supplies this summer. Because of a lack of timely direct access to key information and limitation in other data, GAO was unable to assess likely conditions in California. To make an independent, reliable assessment, GAO would need access to data underlying key supply and demand factors, such as power plant outages and electricity supplies that could be imported into California. Furthermore, forecasts of California's electricity market show stark differences in the expected conditions this summer."

Nuclear Regulatory Commission: Status of Achieving Key Outcomes and Addressing Major Management Challenges

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the Nuclear Regulatory Commission's (NRC) fiscal year 2000 performance report and fiscal year 2002 performance plan required by the Government Performance and Results Act of 1993 to assess its progress in achieving selected key outcomes that are important mission areas for the agency. NRC reports mixed progress in achieving the three outcomes GAO reviewed. To measure performance for the three outcomes, NRC established the same four goals: one relates to safety and three relate to such nonsafety issues as public confidence, regulatory burden, and organizational enhancements. Although NRC's strategies for the safety-related performance goal outcomes seem clear and reasonable, GAO could not assess NRC's performance for the three nonsafety performance goals because NRC only recently developed and reported strategies for them in its fiscal year 2002 performance plan. Because NRC has had little experience in applying the strategies and measures for the three nonsafety goals, it may need to revise them after it completes various planned evaluations during the next three years."

Tobacco Settlement: States' Use of Master Settlement Agreement Payments

A letter report issued by the General Accounting Office with an abstract that begins "The attorneys general of 46 states signed a settlement agreement in 1998 with the nation's largest tobacco companies. The agreement requires the tobacco companies to make annual payments to the states in perpetuity as reimbursement for past tobacco-related costs. Florida, Minnesota, Mississippi, and Texas reached earlier individual settlements with the tobacco companies. States are free to use the money for any purpose. This report examines (1) the amount of payments received by the states and the states' decision-making processes on the allocation of payments in fiscal years 2000 and 2001 and (2) the types of programs that states funded with their payments in those two fiscal years. As of April 2001, GAO found that 45 of the 46 states received nearly $13.5 billion of the $206 billion estimated to be paid by the tobacco companies during the first 25 years of the agreement. Many states established dedicated funds to receive at least part of the payments. Other states passed legislation to ensure that payments are used to supplement existing state funds, enacted laws governing the future use of the payments, established voter approved initiatives to decide …

Energy Markets: Results of Studies Assessing High Electricity Prices in California

A letter report issued by the General Accounting Office with an abstract that begins "Wholesale electricity prices in California rose sharply in May 2000 and have remained high. In addition, there were disruptions in service--blackouts--this winter and spring. The California Independent System Operator, the state agency in charge of balancing electricity supply with demand, expects high prices and service disruptions to continue and perhaps worsen this summer. In response to concerns about high prices and generator outages in California, the Federal Energy Regulatory Commission (FERC) undertook a study, released in February 2001, to determine whether outages were being used to withhold power and drive up prices of electricity in California. Other studies of the electricity market in California have been conducted by economists and industry experts. One study, conducted by three economists from Stanford University, the University of California at Berkeley, and the University of California Energy Institute examined whether market prices of electricity in California in 1998 and 1999 were higher than competitive levels. A second, similar study by two economists--one from the Massachusetts Institute of Technology and one from a private consulting firm--examined the California market during 2000. This report reviews the FERC study, as well as the …

Water Quality: Better Data and Evaluation of Urban Runoff Programs Needed to Assess Effectiveness

A letter report issued by the General Accounting Office with an abstract that begins "The Environmental Protection Agency (EPA) considers the contaminants in storm water runoff as a significant threat to water quality across the nation. Prompted by Congress, EPA has responded with various initiatives, including the National Pollutant Discharge Elimination System Storm Water Program, which requires more than 1,000 local governments to undertake storm water management programs. Those municipalities in Phase I of the program have been trying to reduce pollutants in storm water runoff for several years, and it is time to begin evaluating their efforts. EPA however, has not established measurable goals for this program, nor has it attempted to evaluate the program's effectiveness in reducing storm water pollution or to determine its cost. EPA attributes its inaction to inconsistent data reporting from municipalities, insufficient staff resources, and other competing priorities within the Office of Wastewater Management. Although municipalities report monitoring and cost data to EPA or state regulatory agencies annually, these agencies have not reviewed this information to determine whether it can be useful in determining the program's overall effectiveness or cost. GAO found that the reported cost information will be difficult to analyze unless EPA …

Bureau of Land Management: Improper Charges Made to Mining Law Administration Program

Testimony issued by the General Accounting Office with an abstract that begins "Accurate cost information is crucial for proper program management. Such information is especially important for the Bureau of Land Management's (BLM) Mining Law Administration Program (MLAP) because this program partially funded through mining fees that Congress has earmarked only for mining law administration operations. Some labor costs and several contracts and services were improperly charged to MLAP, causing other subactivities to benefit from funds intended for MLAP operations. Therefore, fewer funds have been available for actual MLAP operations. Although BLM has tried to make correcting adjustments for some of these improper charges, it has not established specific guidance or procedures to prevent improper charging of MLAP funds from recurring. Until additional procedures for MLAP are developed and effectively implemented, Congress and program managers can only place limited reliance on the accuracy of MLAP cost information."

HUD Inspector General: Actions Needed to Strengthen Management and Oversight of Operation Safe Home

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the Department of Housing and Urban Development's (HUD) efforts to combat violent crime and drug trafficking in public housing through Operation Safe Home. GAO found that Operation Safe Home lacks the necessary information systems and management controls to ensure that HUD's Office of Inspector General (OIG) can readily monitor the obligation and expenditure of funds and track the numbers of arrests and convictions. As a result, the OIG cannot reliably allocate program resources or accurately estimate its funding needs. Furthermore, in the absence of complete, consistent, or accurate information, the OIG cannot Congress with reliable and supportable information on Operation Safe Home's accomplishments. The OIG recognizes the need for more effective management controls within Operation Safe Home and has begun to address the problem. These actions, once implemented, should help the OIG to allocate resources more effectively, better estimate future funding needs, and more accurately measure and report the program's accomplishments. However, GAO remains concerned about OIG's long-term involvement in Operation Safe Home. The OIG cannot independently and impartially audit or investigate Operation Safe Home, and may not be perceived as impartial when …

Information Security: Safeguarding of Data in Excessed Department of Energy Computers

A letter report issued by the General Accounting Office with an abstract that begins "The computer systems that support the Department of Energy's (DOE) civilian research and development programs house enormous amounts of data. Although unclassified, some of the information in these systems is nevertheless sensitive and must be protected from inappropriate access or disclosure. For this reason, DOE property management regulations require the agency to clear the hard drives of all computers before they are transferred into the excess category for reuse or disposal. GAO found that DOE lacks standardized instructions, verification procedures, and training for agency and contract employees on how to properly clear excessed computers. DOE also does not ensure that procedures used to remove all software, information, and data from systems are effective. As a result, some of the excessed computers GAO inspected at DOE headquarters had information still stored on the hard drives."

VA Drug Formulary: Better Oversight Is Required, but Veterans Are Getting Needed Drugs

A letter report issued by the General Accounting Office with an abstract that begins "During the last three years, the Department of Veterans Affairs (VA) has made significant progress in establishing its national drug formulary, which has generally met with the prescriber acceptance. Most veterans are receiving the drugs the need and rarely register complaints about prescription drugs. However, VA has not been sufficient to ensure that the Veterans Integrated Service Networks (VISN) and medical centers comply with formulary policies and that the flexibility given to them does not compromise VA's goal of formulary standardization. Contrary to VA formulary policy, some facilities omitted national formulary drugs or modified the closest drug classes. Although a limited number of drugs to supplement the national formulary is permitted, formulary differences among facilities are likely to become more pronounced, as more drugs are added by VISNs, decreasing formulary standardization. VA recognizes the trade-off between local flexibility and standardization, but it lacks criteria for determining the appropriateness of adding drugs to supplement the national formulary and therefore may not be able to determine whether the decrease in standardization is acceptable."

Kosovo Air Operations: Combat Aircraft Basing Plans Are Needed in Advance of Future Conflicts

A letter report issued by the General Accounting Office with an abstract that begins "Following the failure of peace talks and escalating violence against ethnic Albanians in Kosovo, the United States provided military support to the North Atlantic Treaty Organization (NATO) combat operations against Yugoslavia in March 1999. This report reviews how well the United States was prepared for basing its combat aircraft during this operation, called Operation Allied Force. Specifically, GAO determines (1) whether plans were in place to determine where and how to deploy combat aircraft for an operation like Allied Force, (2) how combat aircraft basing decisions were coordinated among the services and allied nations, and (3) whether the United States had the necessary international agreements in place to enable it to quickly execute plans for such an operation. GAO found that the United States had no specific and detailed advanced plans that could be used to determine where and how to deploy its combat aircraft during Operation Allied Force because it was a combination of peacetime and combat operations. Overall plans for operations in defense of NATO members did not apply to this conflict. Although part of the U.S. European Command's mission is to plan for …

Business Systems Modernization: Results of Review of IRS' March 2001 Expenditure Plan

A letter report issued by the General Accounting Office with an abstract that begins "The Internal Revenue Service (IRS) submitted its fourth expenditure plan to Congress in March 2001. In the plan, IRS requested $128 million from its systems modernization appropriations account. This report (1) determines whether the plan satisfied the conditions specified in the acts, (2) determines IRS' progress in implementing modernization management controls and capabilities, and (3) provides other observations about the plan and IRS' Business Systems Modernization program. GAO found that IRS' March 2001 expenditure plan satisfies the conditions specified in the appropriations acts. IRS continues to make important progress in implementing modernization management controls and capabilities but has yet to implement a sufficiently defined version of the enterprise architecture to guide and constrain projects or employ rigorous configuration management practices. Acquiring modernized systems before having the requisite management capacity in place increases the risk of cost, schedule, and performance shortfalls."

Debt Collection: Defense Finance and Accounting Service Needs to Improve Collection Efforts

A letter report issued by the General Accounting Office with an abstract that begins "Improper payments are a long-standing problem throughout the government. The Department of Defense (DOD) has been overpaying contractors by hundreds of millions of dollars each year. For fiscal years 1994 through 1999, DOD contractors returned nearly $1.2 billion that the Defense Finance and Accounting Service (DFAS) had mistakenly paid them as a result of errors, such as paying the same invoice twice or misreading invoice amounts. Sometimes, however, the contractors do not promptly respond to government demands that the overpayments be returned. The Debt Management Office was created at the DFAS Columbus Center to deal with contractors that are unresponsive to the government's demands that overpayments be returned. GAO found that the Debt Management Office at DFAS Columbus is not effectively and proactively pursuing collections of debts assigned to it. Specifically, the Office is not (1) taking appropriate action to establish the validity of the debts that it receives for collection, (2) promptly issuing letters demanding payment, (3) actively communicating with contractors or resolving issues related to the debts, and (4) effectively using the Department of the Treasury's centralized debt collection programs to maximize collections and …

Human Capital: Major Human Capital Challenges at the Departments of Defense and State

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the human capital issues facing the Department of Defense (DOD) and the Department of State. The issues confronting the two agencies do not fundamentally differ from those facing other federal agencies. In the wake of extensive downsizing during the last decade, agency workforces are experiencing significant imbalances in terms of shape, skills, and retirement eligibility, with the likelihood of a huge ware of retirements during the next few years and a resulting decline in the ability to accomplish agency missions. Although both DOD and State have begun to address their human capital issues, GAO identified several areas in which additional efforts are needed. DOD and State must step up their efforts to identify current and future workforce needs, assess where they are relative to those needs, and develop strategies for addressing any related gaps. Such efforts should address workforce shape, skills, knowledge, and succession planning."

Information Security: Code Red, Code Red II, and SirCam Attacks Highlight Need for Proactive Measures

Testimony issued by the General Accounting Office with an abstract that begins "Organizations and individuals have recently had to contend with particularly vexing computer attacks. The most notable is Code Red, but potentially more damaging are Code Red II and SirCam. Together, these attacks have infected millions of computer users, shut down websites, slowed Internet service, and disrupted businesses and government operations. They have already caused billions of dollars of damage, and their full effects have yet to be completely assessed. Code Red and Code Red II are both "worms," which are attacks that propagate themselves through networks without any user intervention or interaction. Both take advantage of a flaw in a component of versions 4.0 and 5.0 of Microsoft's Internet Information Services Web server software. SirCam is a malicious computer virus that spreads primarily through E-mail. Once activated on an infected computer, the virus searches through a select folder and mails user files acting as a "Trojan horse" to E-mail addresses in the user's address book. In addition to spreading, the virus can delete a victim's hard drive or fill the remaining free space on the hard drive, making it impossible to save files or print. On July 19, …

Information Security: Challenges to Improving DOD's Incident Response Capabilities

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the department of Defense's (DOD) implementation of computer incident response capabilities and identifies challenges to improving these. GAO found that during the last several years, DOD has taken several steps to build incident response capabilities and enhance computer defensive capabilities across the Department, including the creation of computer emergency response teams and incident response capabilities within each of the military services as well as the Defense Information Systems Agency and the Defense Logistics Agency. DOD also created the Joint Task Force-Computer Network Defense (JTF-CND) to coordinate and direct the full range of activities within the Department associated with incident response. GAO identified the following six areas in which DOD faces challenges in improving its incident response capabilities: (1) coordinating resource planning and prioritization activities; (2) integrating critical data from intrusion detection systems, sensors, and other devices to better monitor cyber events and attacks; (3) establishing departmentwide process to periodically review systems and networks for security weaknesses; (4) increasing individual unit compliance with departmentwide vulnerability alerts; (5) improving DOD's system for coordinating component-level incident response actions; and (6) developing departmentwide performance measures to assess …
