Correspondence issued by the Government Accountability Office with an abstract that begins "The Emergency Economic Stabilization Act of 2008 (EESA) requires that we annually audit the financial statements of the Troubled Asset Relief Program (TARP) which is implemented by the Office of Financial Stability (OFS). On December 9, 2009, we issued our audit report including (1) an unqualified opinion on OFS's financial statements for TARP as of and for the period ended September 30, 2009, and (2) an opinion that OFS maintained effective internal control over financial reporting as of September 30, 2009. We also reported that our tests of OFS's compliance with selected provisions of laws and regulations for the period ended September 30, 2009, disclosed no instances of noncompliance. Our December 9, 2009, audit report concluded that although certain internal controls could be improved, OFS maintained, in all material respects, effective internal control over financial reporting as of September 30, 2009, that provided reasonable assurance that misstatements, losses, or noncompliance material in relation to the financial statements would be prevented or detected and corrected on a timely basis. Our audit report also identified two significant deficiencies in OFS's internal control over financial reporting. This report presents (1) more …

Troubled Asset Relief Program: Treasury's Framework for Deciding to Extend TARP Was Sufficient, but Could be Strengthened for Future Decisions

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of the Treasury's (Treasury) authority to purchase, commit to purchase, or commit to guarantee troubled assets was set to expire on December 31, 2009. This important authority has allowed Treasury to undertake a number of programs to help stabilize the financial system. In December 2009, the Secretary of the Treasury extended the authority to October 3, 2010. In our October 2009 report on the Troubled Asset Relief Program (TARP), GAO suggested as part of a framework for decision making that Treasury should coordinate with relevant federal agencies, communicate with Congress and the public, and link the decisions related to the next phase of the TARP program to quantitative analysis. This report discusses (1) the process Treasury used to decide to extend TARP and the extent of coordination with relevant agencies and (2) the analytical framework and quantitative indicators Treasury used to decide to extend TARP. To meet the report objectives, GAO reviewed key documents related to the decision to extend TARP, interviewed agency officials and analyzed financial data."

Independent Oversight of Recovery Act Funding for Mississippi's Weatherization Assistance Program

Correspondence issued by the Government Accountability Office with an abstract that begins "The American Recovery and Reinvestment Act of 2009 (Recovery Act) assigns GAO a range of responsibilities to help promote accountability and transparency. One of the act's recurring requirements includes having GAO conduct bimonthly reviews of selected states' and localities' use of funds made available under the act. GAO's review of the use of Recovery Act funding in Mississippi this year included the Weatherization Assistance Program. The Weatherization Assistance Program, administered by the Office of Energy Efficiency and Renewable Energy within the U.S. Department of Energy (DOE), enables low-income families to reduce their utility bills by making long-term energy-efficiency improvements to their homes by, for example, installing insulation, sealing leaks, and modernizing heating equipment, air circulation fans, and air-conditioning equipment. As part of our overall review of the weatherization program in Mississippi, we visited community action agencies responsible for weatherization activities located in Columbia, D'Lo, McComb, and Meridian. In our review of client files, and other data provided by the Division of Community Services (DCS) personnel and one community action agency, we found several problems at the community action agency, which we shared with DCS.

Highway Trust Fund: Nearly All States Received More Funding Than They Contributed in Highway Taxes Since 2005

A letter report issued by the Government Accountability Office with an abstract that begins "Federal funding for highways is provided to the states mostly through a series of grant programs known as the Federal-Aid Highway Program, administered by the Department of Transportation's (DOT) Federal Highway Administration (FHWA). In 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) authorized $197.5 billion for the Federal-Aid Highway Program for fiscal years 2005 through 2009. The program operates on a "user pay" system, wherein users contribute to the Highway Trust Fund through fuel taxes and other fees. The distribution of funding among the states has been a contentious issue. States that receive less than their highway users contribute are known as "donor" states and states that receive more than their highway users contribute are known as "donee" states. GAO was asked to examine for the SAFETEA-LU period (1) how contributions to the Highway Trust Fund compared with the funding states received, (2) what provisions were used to address rate-of-return issues across states, and (3) what additional factors affect the relationship between contributions to the Highway Trust Fund and the funding states receive.

Hurricane Katrina: CMS and HRSA Assistance to Sustain Primary Care Gains in the Greater New Orleans Area

Correspondence issued by the Government Accountability Office with an abstract that begins "More than 4 years after Hurricane Katrina made landfall, the greater New Orleans area continues to face challenges restoring health care services disrupted by the storm and flooding that followed. In July 2007, the U.S. Department of Health and Human Services (HHS) awarded the $100-million Primary Care Access and Stabilization Grant (PCASG) to the Louisiana Department of Health and Hospitals (LDHH). The PCASG was intended to restore and expand access to primary care services in the greater New Orleans area without regard to a patient's ability to pay. The PCASG was designed to provide a temporary funding source--from July 23, 2007, through September 30, 2010. Despite the various types of assistance offered, concerns remain about whether the primary care gains made will be sustainable after the PCASG funding ends. Given the federal investment in providing and sustaining health care in the greater New Orleans area, Congreess asked GAO to describe what steps CMS and the Health Resources and Services Administration (HRSA) have taken to help the PCASG-funded organizations--LDHH, LPHI, and the PCASG-funded providers--sustain the primary care gains made in the greater New Orleans area."

Contracting Strategies: Better Data and Management Needed to Leverage Value of Interagency and Enterprisewide Contracts

Testimony issued by the Government Accountability Office with an abstract that begins "Agencies can use several different types of contracts to leverage the government's buying power for goods and services. These include interagency contracts--where one agency uses another's contract for its own needs--such as the General Services Administration (GSA) and the Department of Veterans Affairs multiple award schedule (MAS) contracts, multiagency contracts (MAC) for a wide range of goods and services, and governmentwide acquisition contracts (GWAC) for information technology. Agencies spent at least $60 billion in fiscal year 2008 through these contracts and similar single-agency enterprisewide contracts. GAO was asked to testify on the management and oversight of interagency contracts, and how the government can ensure that interagency contracting is efficient and transparent. GAO's testimony is based on its recent report, Contracting Strategies: Data and Oversight Problems Hamper Opportunities to Leverage Value of Interagency and Enterprisewide Contracts (GAO-10-367, April 2010). In that report, GAO made recommendations to the Office of Management and Budget (OMB) to strengthen policy, improve data, and better coordinate agencies' awards of MACs and enterprisewide contracts, and to GSA to improve MAS program pricing and management. Both agencies concurred with GAO's recommendations."

Aviation Security: Progress Made but Actions Needed to Address Challenges in Meeting the Air Cargo Screening Mandate

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses air cargo screening. In 2008, about 7.3 billion pounds of cargo was transported on U.S. passenger flights--approximately 58 percent of which was transported domestically (domestic cargo) and 42 percent of which was transported on flights arriving in the United States from a foreign location (inbound cargo). The 2009 Christmas Day plot to detonate an explosive device during an international flight bound for Detroit provided a vivid reminder that terrorists continue to view passenger aircraft as attractive targets. According to the Transportation Security Administration (TSA), the security threat posed by terrorists introducing explosive devices in air cargo shipments is significant, and the risk and likelihood of such an attack directed at passenger aircraft is high. To help enhance the security of air cargo, the Implementing Recommendations of the 9/11 Commission Act of 2007 (9/11 Commission Act) mandated the Department of Homeland Security (DHS) to establish a system to physically screen 50 percent of cargo on passenger aircraft--including the domestic and inbound flights of foreign and U.S. passenger operations--by February 2009, and 100 percent of such cargo by August 2010.

The Lake Charles CCS Project (open access)

The Lake Charles CCS Project

The Lake Charles CCS Project is a large-scale industrial carbon capture and sequestration (CCS) project which will demonstrate advanced technologies that capture and sequester carbon dioxide (CO{sub 2}) emissions from industrial sources into underground formations. Specifically the Lake Charles CCS Project will accelerate commercialization of large-scale CO{sub 2} storage from industrial sources by leveraging synergy between a proposed petroleum coke to chemicals plant (the LCC Gasification Project) and the largest integrated anthropogenic CO{sub 2} capture, transport, and monitored sequestration program in the U.S. Gulf Coast Region. The Lake Charles CCS Project will promote the expansion of EOR in Texas and Louisiana and supply greater energy security by expanding domestic energy supplies. The capture, compression, pipeline, injection, and monitoring infrastructure will continue to sequester CO{sub 2} for many years after the completion of the term of the DOE agreement. The objectives of this project are expected to be fulfilled by working through two distinct phases. The overall objective of Phase 1 was to develop a fully definitive project basis for a competitive Renewal Application process to proceed into Phase 2 - Design, Construction and Operations. Phase 1 includes the studies attached hereto that will establish: the engineering design basis for the …

Catalyzed Nano-Framework Stablized High Density Reversible Hydrogen Storage Systems (open access)

Catalyzed Nano-Framework Stablized High Density Reversible Hydrogen Storage Systems

A wide range of high capacity on-board rechargeable material candidates have exhibited non-ideal behavior related to irreversible hydrogen discharge / recharge behavior, and kinetic instability or retardation. This project addresses these issues by incorporating solvated and other forms of complex metal hydrides, with an emphasis on borohydrides, into nano-scale frameworks of low density, high surface area skeleton materials to stabilize, catalyze, and control desorption product formation associated with such complex metal hydrides. A variety of framework chemistries and hydride / framework combinations were investigated to make a relatively broad assessment of the method'™s potential. In this project, the hydride / framework interactions were tuned to decrease desorption temperatures for highly stable compounds or increase desorption temperatures for unstable high capacity compounds, and to influence desorption product formation for improved reversibility. First principle modeling was used to explore heterogeneous catalysis of hydride reversibility by modeling H{sub 2} dissociation, hydrogen migration, and rehydrogenation. Atomic modeling also demonstrated enhanced NaTi(BH{sub 4}){sub 4} stabilization at nano-framework surfaces modified with multi-functional agents. Amine multi-functional agents were found to have more balanced interactions with nano-framework and hydride clusters than other functional groups investigated. Experimentation demonstrated that incorporation of Ca(BH{sub 4}){sub 2} and Mg(BH{sub 4}){sub 2} in …

Carbon Mineralization by Aqueous Precipitation for Beneficial Use of CO2 from Flue Gas

Calera's innovative Mineralization via Aqueous Precipitation (MAP) technology for the capture and conversion of CO{sub 2} to useful materials for use in the built environment was further developed and proven in the Phase 1 Department of Energy Grant. The process was scaled to 300 gallon batch reactors and subsequently to Pilot Plant scale for the continuous production of product with the production of reactive calcium carbonate material that was evaluated as a supplementary cementitious material (SCM). The Calera SCM{trademark} was evaluated as a 20% replacement for ordinary portland cement and demonstrated to meet the industry specification ASTM 1157 which is a standard performance specification for hydraulic cement. The performance of the 20% replacement material was comparable to the 100% ordinary portland cement control in terms of compressive strength and workability as measured by a variety of ASTM standard tests. In addition to the performance metrics, detailed characterization of the Calera SCM was performed using advanced analytical techniques to better understand the material interaction with the phases of ordinary portland cement. X-ray synchrotron diffraction studies at the Advanced Photon Source in Argonne National Lab confirmed the presence of an amorphous phase(s) in addition to the crystalline calcium carbonate phases in the …
