The LIMB (limestone injection multi-stage burner) process offers special potential for reducing NO/sub x/ and SO/sub x/ by at least 50 percent in coal combustion. This is to be accomplished by adding limestone with fuel and/or air in a low NO/sub x/ burner. This program has been directed to defining the chemistry and kinetics necessary to optimize sulfur capture in LIMB combustion. More specifically, this program has attempted to clarify the role of calcium sulfide in LIMB chemistry. When limestone is added in a staged burner, there is a strong possibility that under certain circumstances CaS is produced in the reducing (fuel-rich) zone of the burner. Since CaS is more stable than CaSO/sub 4/, this affords the opportunity to (1) operate the burner at a higher temperature, 2200 to 2500 F, (2) pass the CaS rapidly through the high temperature zone (before dissociation), and (3) complete the combustion in a lean (air-rich) region where the sulfur is finally retained in CaSO/sub 4/. For these reasons this program has concentrated on the high temperature chemistry and kinetics of CaS. To achieve the program objective, the program was divided into three tasks. These involved (1) a study of CaS formation, (2) a …

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Motor Carrier Safety Administration (FMCSA) is responsible for improving commercial vehicle safety and uses education and outreach as part of its efforts. The House report accompanying the fiscal year 2005 Department of Transportation (DOT) appropriations bill asked GAO to report on FMCSA's education and outreach programs to the House and Senate Committees on Appropriations. GAO (1) describes FMCSA's education and outreach programs and how they relate to FMCSA's goals (2) identifies the extent to which FMCSA has evaluated its education and outreach programs and (3) describes the extent to which FMCSA's education and outreach programs are effective."

A letter report issued by the Government Accountability Office with an abstract that begins "Medicare Advantage (MA) organizations' actual medical expenses, nonmedical expenses (such as marketing, sales, and administration) and profits as a percentage of total revenue were, on average, similar to projected values for plans available to all beneficiaries in 2011, the most recent year for which data were available at the time of the request for this work. MA organizations' actual medical expenses, nonmedical expenses, and profits were 86.3 percent, 9.1 percent, and 4.5 percent of total revenue, respectively. As a percentage of revenue, all three categories were within 0.3 percentage points of what MA organizations had projected. In addition, MA organizations received, on average, $9,893 in total revenue per beneficiary, slightly higher than the projected amount of $9,635."

A letter report issued by the Government Accountability Office with an abstract that begins "Agency officials told us that enhanced use leases (EUL) help them utilize their underutilized property better; commonly cited benefits include enhanced mission activities, cash rent revenue, and value received through in-kind consideration. However, some agencies we reviewed do not include all costs associated with their EULs when they assess the performance of their EUL programs. Guidance from the Office of Management and Budget (OMB) does not specify what costs agencies should include in their EUL evaluations, resulting in variance among agencies. For example, the Department of Veterans Affairs (VA) and the Department of State do not consistently attribute EUL-related costs of consultant staff who administer the leases, and VA does not attribute various administrative costs that offset EUL benefits. Without fully accounting for all EUL costs, agencies may overstate the net benefits of their EUL programs."

A letter report issued by the General Accounting Office with an abstract that begins "Surveys suggest that as many as two-thirds of American households have donated money to charitable organizations to aid in the response to the September 11 disasters. To provide the public with information on the role of charitable aid in assisting those affected by the attacks, GAO was asked to report on the amount of donations charities raised and distributed, the accountability measures in place to prevent fraud by organizations and individuals, and lessons learned about how to best distribute charitable aid in similar situations."

A letter report issued by the Government Accountability Office with an abstract that begins "To develop a national benchmark for retail pharmacy acquisition costs of Medicaid covered outpatient prescription drugs--known as the National Average Drug Acquisition Cost (NADAC)--the Centers for Medicare & Medicaid Services (CMS) within the Department of Health and Human Services (HHS) surveys each month randomly selected retail community pharmacies for invoice data on their actual drug acquisition costs. CMS then calculates an average acquisition cost for each drug based on invoice data received from about 500 to 600 pharmacies. CMS officials expressed confidence in their current process, but noted that some limitations may exist. For example, CMS officials stated the extent to which NADACs reflect rebates and discounts is limited because most occur off-invoice or are not tied to a specific drug purchase. CMS has developed and published more than 5,000 NADACs, which CMS has estimated apply to more than 90 percent of the drug claims reimbursed by Medicaid."

A letter report issued by the Government Accountability Office with an abstract that begins "The livestock industry, which contributes over $100 billion annually to the national economy, is vulnerable to foreign animal diseases that, if introduced in the United States, could cause severe economic losses. To protect against such losses, critical research and diagnostic activities are conducted at the Plum Island Animal Disease Center in New York. The Department of Agriculture (USDA) was responsible for Plum Island until June 2003, when provisions of the Homeland Security Act of 2002 transferred the facility to the Department of Homeland Security (DHS). Under an interagency agreement, USDA continues to work on foreign animal diseases at the island. GAO examined (1) DHS and USDA coordination of research and diagnostic activities, (2) changes in research and diagnostic priorities since the transfer, and (3) long-term objectives of joint activities at Plum Island."

A letter report issued by the Government Accountability Office with an abstract that begins "The Ryan White Comprehensive AIDS Resources Emergency Act of 1990 (CARE Act) makes federal funds available to assist those infected and affected by HIV/AIDS. Through the CARE Act, the Health Resources and Services Administration (HRSA), part of the Department of Health and Human Services (HHS), awards grants (known as Part D grants) to provide services to women, infants, children, and youth with HIV/AIDS and their families. These grantees incur administrative expenses and indirect costs, such as rent and utilities. The Ryan White HIV/AIDS Treatment and Modernization Act of 2006 (RWTMA), which took effect in fiscal year 2007, capped at 10 percent the amount that Part D grantees could spend on administrative expenses. According to HRSA, there is no cap on indirect costs, but grantees must have an indirect cost rate to use funds for indirect costs. RWTMA directed GAO to examine Part D spending. In this report GAO describes (1) the services that Part D grantees provide and what effect, if any, the administrative expense cap has had on those services and on grantee programs; (2) how Part D grantees report on administrative expenses, indirect costs, …

A letter report issued by the Government Accountability Office with an abstract that begins "The Transportation Security Administration (TSA) has inconsistently overseen and enforced its rail security incident reporting requirement because it does not have guidance and its oversight mechanisms are limited, leading to considerable variation in the types and number of incidents reported. Though some variation is expected in the number and type of incidents reported because of differences in rail agency size, location, and ridership, local TSA inspection officials have provided rail agencies with inconsistent interpretations of the reporting requirement. For example, local TSA officials instructed one rail agency to report all incidents related to individuals struck by trains. However, local TSA officials responsible for another rail agency said these incidents would not need to be reported as they are most often suicides with no nexus to terrorism. Providing guidance to local TSA inspection officials and rail agencies on the types of incidents that are to be reported could improve consistency across different TSA field offices. GAO also found inconsistency in TSA compliance inspections and enforcement actions because TSA has not utilized limited headquarters-level mechanisms as intended for ensuring consistency in these activities. TSA's rail security inspection policies …

A letter report issued by the Government Accountability Office with an abstract that begins "In 2001, the Department of Defense (DOD) identified performance based logistics (PBL) as the preferred weapon system support strategy. Within DOD, PBL is the purchase of performance outcomes, such as system availability, rather than the purchase of individual elements of logistics support--such as parts, repairs, and engineering support. Although PBL initially arose from efforts to reduce support costs, questions have arisen about whether PBL has reduced support costs as originally intended. GAO was asked to evaluate the extent to which DOD has used business case analyses to guide decisions related to PBL arrangements and the impact PBL arrangements have had on weapon system support costs. In conducting the review, GAO analyzed the implementation of PBL arrangements for 29 weapon system programs. GAO also looked at the use and characteristics of performance-based contracting in the United Kingdom's Ministry of Defence."

A letter report issued by the Government Accountability Office with an abstract that begins "Law enforcement officers (LEOs) within the federal government play a key role in maintaining the safety and security of federal property, employees, and the general public. In this report, we describe the number of LEOs that federal civilian law enforcement components employed as of June 30, 2006; the federal job series classifications the components used to employ LEOs; and the sources of their primary legal authorities. To identify federal components that employ LEOs, we consulted, among other sources, the Federal Citizen Information Center's Cabinet Agencies and Independent Agencies and Commissions Directory; a list of organizations included in the Federal Law Enforcement Training Center (FLETC) 2004-2005 List of Agencies Trained at FLETC; and federal agencies listed in Federal Law Enforcement Officers, 2002, published by the Department of Justice's Bureau of Justice Statistics (BJS). We identified 104 federal civilian law enforcement components and administered two Web-based surveys to each--one survey on the primary authorities and the other survey on the job series classifications. We defined an LEO as an individual authorized to perform any of four specific functions: (1) conduct criminal investigations, (2) execute search warrants, (3) make …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy (DOE) faces significant technical challenges in successfully constructing and operating the Waste Treatment and Immobilization Plant (WTP) project that is to treat millions of gallons of highly radioactive liquid waste resulting from the production of nuclear weapons. DOE and Bechtel National, Inc. identified hundreds of technical challenges that vary in significance and potential negative impact and have resolved many of them. Remaining challenges include (1) developing a viable technology to keep the waste mixed uniformly in WTP mix tanks to both avoid explosions and so that it can be properly prepared for further processing; (2) ensuring that the erosion and corrosion of components, such as tanks and piping systems, is effectively mitigated; (3) preventing the buildup of flammable hydrogen gas in tanks, vessels, and piping systems; and (4) understanding better the waste that will be processed at the WTP. Until these and other technical challenges are resolved, DOE will continue to be uncertain whether the WTP can be completed on schedule and whether it will operate safely and effectively."

A letter report issued by the Government Accountability Office with an abstract that begins "Collectively, the Department of Defense (DOD) gives its contractors the opportunity to earn billions of dollars through monetary incentives--known as award fees and incentive fees. These fees are intended to motivate excellent contractor performance in areas deemed critical to an acquisition program's success, with award fees being appropriate when contracting and program officials cannot devise objective incentive fee targets related to cost, technical performance, or schedule. GAO was asked to determine whether award and incentive fees have been used effectively as a tool for achieving DOD's desired acquisition outcomes. To do this, GAO selected a probability sample of 93 contracts from the study population of 597 DOD award- and incentive-fee contracts that were active and had at least one contract action valued at $10 million or more from fiscal year 1999 through 2003."

A letter report issued by the Government Accountability Office with an abstract that begins "U.S. source income flows to recipients offshore through foreign financial institutions and U.S. withholding agents. The Internal Revenue Service (IRS) established the Qualified Intermediary (QI) program to improve tax withholding and reporting on such income. QIs are foreign financial institutions that contract with IRS to withhold and report U.S. tax. GAO was asked to (1) describe program features, (2) assess whether weaknesses exist in the U.S. withholding system for U.S. source income, and (3) identify any weaknesses in QI external reviews and IRS's use of program data. GAO interviewed agency officials and private practitioners and reviewed the latest IRS data on U.S. source income flowing offshore."

A letter report issued by the Government Accountability Office with an abstract that begins "Of the 71 nonmajor projects that the Department of Energy's (DOE) Office of Environmental Management (EM) and National Nuclear Security Administration (NNSA) completed or had under way from fiscal years 2008 to 2012, 21 met or are expected to meet their performance targets for scope, cost, and completion date. These projects included a $22 million EM project to expand an existing waste disposal facility at the Oak Ridge Reservation in Tennessee and a $199 million NNSA project to equip a radiological laboratory and office building at the Los Alamos National Laboratory in New Mexico. Another 23 projects did not meet or were not expected to meet one or more of their three performance targets for scope, cost, and completion date. Among these, 13 projects met or are expected to meet two targets, including a $548 million NNSA project to shut down a nuclear reactor in Russia for nonproliferation purposes; 8 projects met or are expected to meet one target; 1 project did not meet any of its targets; and 1 project was cancelled. Of the remaining 27 projects, many had insufficiently documented performance targets for scope, …

A letter report issued by the General Accounting Office with an abstract that begins "The Sarbanes-Oxley Act of 2002 created, among other things, the Public Company Accounting Oversight Board (PCAOB) to oversee audits of public companies. A divided Securities and Exchange Commission (SEC) appointed the first PCAOB on October 25, 2002. Amid allegations that the SEC Chairman withheld relevant information from the other Commissioners concerning the suitability of the newly appointed PCAOB chairman, GAO was asked to examine SEC's selection process; determine whether the SEC Chairman withheld information from other Commissioners; determine what vetting of candidates took place; and identify what actions led to breakdowns in the process."

A letter report issued by the General Accounting Office with an abstract that begins "Amid heightened awareness that many patients with cancer and other chronic diseases suffer from undertreated pain, the Food and Drug Administration (FDA) approved Purdue Pharma's controlled-release pain reliever OxyContin in 1995. Sales grew rapidly, and by 2001 OxyContin had become the most prescribed brandname narcotic medication for treating moderate-to-severe pain. In early 2000, reports began to surface about abuse and diversion for illicit use of OxyContin, which contains the opioid oxycodone. GAO was asked to examine concerns about these issues. Specifically, GAO reviewed (1) how OxyContin was marketed and promoted, (2) what factors contributed to the abuse and diversion of OxyContin, and (3) what actions have been taken to address OxyContin abuse and diversion."

A letter report issued by the General Accounting Office with an abstract that begins "The Chairman and Ranking Minority Member, Senate Committee on Veterans' Affairs, asked GAO to assist the Committee in its oversight of the Veterans Benefits Administration's (VBA) efforts to improve compensation and pension claims processing. As part of this effort, GAO assessed (1) whether VBA's key timeliness measure clearly reflects its performance and (2) whether it has adequate data to measure the timeliness of its newly created specialized claims processing teams."
