The overall objective of the Full-Scale Low-NOx Cell (LNC) Burner Retrofit project is to demonstrate the cost-effective reduction of NOx generated by a large, base-loaded (70% capacity factor or greater), coal-fired utility boiler. Specific objectives include: at least 50% NOx reduction over standard two-nozzle cell burners, without degradation of boiler performance or life; acquire and evaluate emission and boiler performance data before and after the retrofit to determine NOx reduction and impact on overall boiler performance; and demonstrate that the LNC burner retrofits are the most cost-effective alternative to emerging, or commercially- available NOx control technology for units equipped with cell burners. The focus of this demonstration is to determine maximum NOx reduction capabilities without adversely impacting plant performance, operation and maintenance.

A letter report issued by the Government Accountability Office with an abstract that begins "The Energy Policy Act of 2005 (Act) contains provisions that address a variety of challenges that face the geothermal industry, including the high risk and uncertainty of developing geothermal power plants, lack of sufficient transmission capacity, and delays in federal leasing. Among the provisions are means to simplify federal royalties on geothermal resources while overall collecting the same level of royalty revenue. The Act also changes how these royalties are to be shared with local governments (disbursements). This report describes: (1) the current extent of and potential for geothermal development; (2) challenges faced by developers of geothermal resources; (3) federal, state, and local government actions to address these challenges; and (4) how provisions of the Act are likely to affect federal geothermal royalty disbursement and collections."

A letter report issued by the Government Accountability Office with an abstract that begins "Through its Section 232 program, the Department of Housing and Urban Development's (HUD) Federal Housing Administration (FHA) insures approximately $12.5 billion in mortgages for residential care facilities. In response to a requirement in the 2005 Consolidated Appropriations Conference Report and a congressional request, GAO examined (1) HUD's management of the program, including loan underwriting and monitoring; (2) the extent to which HUD's oversight of insured facilities is coordinated with the states' oversight of quality of care; (3) the financial risks the program poses to HUD's General Insurance/Special Risk Insurance (GI/SRI) Fund; and (4) how HUD estimates the annual credit subsidy cost for the program."

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service (IRS) and foreign tax administrators face similar issues regardless of the particular provisions of their laws. These issues include, for example, helping taxpayers prepare and file returns, and assuring tax compliance. Understanding how other tax administrators have used certain practices to address common issues can provide insights to help inform deliberations about tax reform and about possible administrative changes in the U.S. existing system to improve compliance, better serve taxpayers, reduce burdens, and increase efficiencies. GAO was asked to describe (1) how foreign tax administrators have approached issues that are similar to those in the U.S. tax system and (2) whether and how the IRS identifies and adopts tax administration practices used elsewhere. To do this, GAO reviewed documents and interviewed six foreign tax administrators. In some cases, GAO also interviewed tax experts, tax practitioners, taxpayers, and trade-group representatives who were selected based on their expertise or involvement in developing or using the foreign systems. GAO also examined documents and met with IRS officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Advanced SEAL Delivery System (ASDS) is a hybrid combatant submersible providing clandestine delivery and extraction of Navy SEALs and equipment in high-threat environments. The first ASDS has had significant performance issues and has cost, to date, over $885 million. In May 2006, Congress requested that GAO review ASDS. This report examines (1) how the Navy managed ASDS risks through its contracts and (2) the status of major technical issues and program restructuring."

A letter report issued by the General Accounting Office with an abstract that begins "Congress is considering legislation to authorize IRS to contract with private collection agencies (PCA) and to pay them out of the tax revenue that they collect. Some have expressed concerns that this proposal might be unsuccessful, inefficient, or result in taxpayers being mistreated or having their private tax information compromised. This report discusses (1) the critical success factors for contracting with PCAs for tax debt collection; (2) IRS's actions to address these factors in developing the PCA program and actions left to be done; and (3) whether IRS, if it receives the authority to use PCAs, plans to do a study that will help policy makers judge whether PCAs are the best use of funds to meet IRS's collection objectives."

A letter report issued by the Government Accountability Office with an abstract that begins "Due to concerns about domestic violence in the military and its adverse effect on mission readiness, Congress required the Department of Defense (DOD) to establish a task force to assess the services' response to domestic violence and recommend improvements. The task force issued three reports containing 194 recommendations. The Fiscal Year 2004 National Defense Authorization Act required GAO to review DOD's progress in implementing the recommendations. This report discusses (1) DOD's ability to report on domestic violence incidents and disciplinary actions, (2) the resources DOD has provided to implement the recommendations, and (3) DOD's specific actions to ensure victim confidentiality and the education of commanding officers, senior enlisted personnel, and chaplains. GAO also examined whether DOD has established an oversight framework to monitor implementation."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2002, Congress enacted the Jobs for Veterans Act (JVA), which modified two Department of Labor (Labor) programs that specifically target veteran job seekers: the Disabled Veterans' Outreach Program (DVOP) and the Local Veterans' Employment Representative (LVER) program. However, questions have been raised about the adequacy of performance information on services to veterans by these and other employment programs. In this report, GAO examined (1) the extent to which DVOP and LVER performance information reflects services and outcomes for veterans; (2) the extent to which performance information on veterans paints a clear picture of their use of one-stop services; and (3) what Labor is doing to improve the quality of performance data and better understand program impact and outcomes for veterans."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) wants to create a networked force where soldiers and systems are able to operate together seamlessly. To help facilitate this transformation, DOD began the Transformational Satellite Communications System (TSAT) program in January 2004. We reported in 2003 that TSAT was about to begin without sufficiently mature technology. In this report, at your request, we followed up with an assessment of (1) how the TSAT program is progressing, and (2) whether the program is using an acquisition approach that will provide the knowledge needed to enter product development."

A letter report issued by the General Accounting Office with an abstract that begins "Clean Water Act regulations generally prohibit boats from discharging untreated sewage but allow the discharge of treated sewage using certified marine sanitation devices. The act allows states to designate "no-discharge zones"--areas in which vessels are prohibited from discharging any sewage--if the Environmental Protection Agency (EPA) finds that adequate facilities exist in such zones for the removal and treatment of sewage from vessels. In some cases, such as for drinking water intake zones, EPA makes the designation. As requested, this report assesses (1) EPA's process for determining the adequacy of facilities to remove and treat sewage in proposed no-discharge zones; (2) the extent to which EPA and the states ensure that adequate facilities remain available after designation; (3) the extent to which the Coast Guard and the states enforce discharge prohibitions; and (4) various effects of no-discharge zones, as identified by EPA, states, and localities."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) relies on a network of DOD and non-DOD infrastructure assets in the United States and abroad so critical that its unavailability could hinder DOD's ability to project, support, and sustain its forces and operations worldwide. DOD established the Defense Critical Infrastructure Program (DCIP) to identify and assure the availability of mission-critical infrastructure. GAO was asked to evaluate the extent to which DOD has (1) developed a comprehensive management plan to implement DCIP and (2) identified, prioritized, and assessed its critical infrastructure. GAO analyzed relevant DCIP documents and guidance and met with officials from more than 30 DOD organizations that have DCIP responsibilities, and with Department of Homeland Security (DHS) officials involved in protecting critical infrastructure."

A letter report issued by the General Accounting Office with an abstract that begins "Success in the war against terrorism requires the United States to effectively research, develop, and deploy technologies to detect and respond to the use of nuclear, biological, and chemical weapons. The Homeland Security Act of 2002 gave the Department of Homeland Security (DHS) the ability to use laboratories owned by the Department of Energy (DOE) to conduct research and development (R&D) of these advanced technologies. GAO was asked to determine (1) whether DHS has completed a strategic R&D plan and coordinated its efforts with other federal agencies, (2) how DHS plans to use DOE's laboratories to carry out its R&D, and (3) what controls DHS is establishing to monitor projects at DOE's laboratories."

A letter report issued by the General Accounting Office with an abstract that begins "Twenty-four states and the District of Columbia have restructured electricity markets by shifting from service provided through a regulated monopoly to service provided through open competition among the local utilities and their competitors. The restructuring was intended to boost competition and expand consumer choice, increase efficiency, and lower prices. Of the three states GAO studied, Texas had the greatest need for additional electric power, and it added the most new capacity from 1995 through 2001. In contrast, California added 25 percent of the forecasted need for capacity over this period. Although Pennsylvania added less than half of its forecasted need for capacity, the state continues to be a net exporter of electricity to nearby states. The three states have similar processes for approving applications to build and operate new power plants. In all three states, state and local agencies must review the applications to ensure that the developer complies with environmental, land use, and other requirements before issuing the permits necessary to build and operate a power plant. California also has a state energy commission that reviews each power plant application to determine whether the benefits …

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO reviewed the Internal Revenue Service's (IRS) second Information Technology Investment Account (ITIA) expenditure plan, focusing on: (1) the progress IRS has made in meeting the commitments in its first expenditure plan; (2) whether the plan satisfies the conditions specified in the Department of the Treasury's fiscal year 1998 and 1999 appropriations acts; (3) whether the plan is consistent with GAO's open recommendations on IRS' systems modernization; and (4) whether GAO have any other observations about IRS' systems modernization efforts."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1995, GAO has designated the Department of Defense's (DOD) multibillion dollar business systems modernization program as high risk, and it continues to do so today. To assist in addressing DOD's modernization challenges, the Ronald W. Reagan National Defense Authorization Act for Fiscal Year 2005 (the act) requires the department to, among other things, report specific information about business system investments, including (1) milestones and actual performance against specified measures and any revisions and (2) actions taken to certify that a modernization investment involving more than $1 million meets defined conditions before obligating funds. The act also directs GAO to review each report. As agreed, GAO focused on the fiscal year 2010 report's compliance with, among other things, these provisions of the act. To do so, GAO compared DOD's report to the act's reporting requirements, interviewed DOD officials, analyzed relevant documentation, and leveraged prior GAO reports."

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) National Research Program (NRP) has helped test or develop practices that have been used in operational examinations of individual tax returns, according to IRS officials. These practices include, for example, helping test IRS's remote learning system and helping IRS adopt new examination support software."

A letter report issued by the Government Accountability Office with an abstract that begins "Alien smuggling along the southwest border is a threat to the security of the United States and Mexico. Within the Department of Homeland Security (DHS), the Office of Investigations (OI)--part of U.S. Immigration and Customs Enforcement (ICE)--is the primary federal agency responsible for investigating alien smuggling along the southwest border. As requested, this report addresses, for the southwest border, (1) OI's efforts to counter alien smuggling since 2005, and opportunities, if any, for ICE to use its resources more effectively; (2) the progress DHS has made in seizing alien smugglers' assets since fiscal year 2005 and any promising techniques that could be applied to seize smugglers' assets; and (3) the extent to which ICE has objectives related to alien smuggling and measures to assess progress. GAO interviewed officials in all four OI offices along the southwest border and analyzed data on OI's cases and seizures, from fiscal years 2005 through 2009."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the impact of operations other than war (OOTW) on the military services, focusing on the: (1) impact of OOTW on the warfighting capability of each of the services, including the time to recover warfighting skills; (2) extent to which reporting systems fully capture the impacts; (3) available information on the effect of OOTW on morale and retention; (4) ability of U.S. forces to respond to a major theater war while engaged in OOTW; (5) Department of Defense (DOD) efforts to alleviate any adverse impacts; and (6) funding provided by Congress for OOTW."

A chapter report issued by the General Accounting Office with an abstract that begins "This report discusses the Drug Enforcement Administration's (DEA) Mobile Enforcement Team Program. GAO found that since the program was established in 1995, DEA has enhanced its management of the program and provided for greater headquarters oversight and monitoring. In implementing the program and carrying out deployments, the field division METs generally complied with some of the pertinent requirements and guidelines that GAO reviewed. However, some DEA headquarters files did not contain adequate documentation, GAO could not determine whether the METs consistently and adequately assessed the requesting local law enforcement agencies' abilities to address, on their own, the drug and related violence problems for which DEA's program assistance was requested. DEA expects the program to focus on specific, targeted gangs in the areas in which the METs are deployed and that deployments will generally continue until the targeted individuals are arrested and the targeted drug gangs have been disrupted or dismantled. Consistent with the nature and objectives of the program, investigators focused primarily on street-level drug dealers and were mostly local and regional in scope. DEA collects data on various performance measures to assess the results of …
