Grants Management: EPA Needs to Strengthen Efforts to Provide the Public with Complete and Accurate Information on Grant Opportunities

Correspondence issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) has faced persistent challenges for many years in managing its grants, which constitute over one-half of the agency's budget, or about $4 billion annually. Among other things, EPA has been criticized for not always promoting competition in awarding grants, including not completely and accurately announcing grant opportunities to the public and potential applicants. One avenue EPA uses to inform the public about grant opportunities is the Catalog of Federal Domestic Assistance (CFDA), the federal government's listing of available grants and other federal funding opportunities. EPA's Office of Grants and Debarment (OGD), among other things, develops grants policy and guidance and compiles grant information for the CFDA. OGD has taken several steps to address criticism regarding the lack of complete and accurate information in the CFDA. In this context the Chairman, Senate Committee on Environment and Public Works, asked us to determine whether EPA is providing complete and accurate information on grant opportunities to the public in the CFDA."

Nuclear Weapons: NNSA Needs to Refine and More Effectively Manage Its New Approach for Assessing and Certifying Nuclear Weapons

A letter report issued by the Government Accountability Office with an abstract that begins "In 1992, the United States began a unilateral moratorium on the testing of nuclear weapons. To compensate for the lack of testing, the Department of Energy's National Nuclear Security Administration (NNSA) developed the Stockpile Stewardship Program to assess and certify the safety and reliability of the nation's nuclear stockpile without nuclear testing. In 2001, NNSA's weapons laboratories began developing what is intended to be a common framework for a new methodology for assessing and certifying the safety and reliability of the nuclear stockpile without nuclear testing. GAO was asked to evaluate (1) the new methodology NNSA is developing and (2) NNSA's management of the implementation of this new methodology."

Social Security: Long-Term Challenges Warrant Early Action

Testimony issued by the Government Accountability Office with an abstract that begins "Social Security is the foundation of the nation's retirement income system, helping to protect the vast majority of American workers and their families from poverty in old age. However, it is much more than a retirement program and also provides millions of Americans with disability insurance and survivors' benefits. Over the long term, as the baby boom generation retires and as Americans continue to live longer and have fewer children, Social Security's financing shortfall presents a major program solvency and sustainability challenge that is growing as time passes. The Chairman and Ranking Member of the Senate Special Committee on Aging asked GAO to discuss the future of the Social Security program. This testimony will address the nature of Social Security's long-term financing problem and why it is preferable for Congress to take action sooner rather than later, as well as the broader context in which reform proposals should be considered."

Applying Agreed-Upon Procedures: House Interparliamentary Groups

Correspondence issued by the Government Accountability Office with an abstract that begins "GAO agreed to assist Congress in evaluating the extent to which the Schedules of Receipts, Disbursements, and Fund Balance for five Interparliamentary Groups appropriately reflect the actual cash receipts and disbursements and related fund balances for the years ended December 31, 2002, and 2001. These five groups were the Mexico-United States Interparliamentary Group, Canada-United States Interparliamentary Group, Transatlantic Legislators' Dialogue, United States Group of the NATO Parliamentary Assembly, and British-American Parliamentary Group. Congress asked us to (1) compare recorded receipts to appropriation requests, bank statements, and other supporting documentation; (2) compare recorded disbursements to vouchers, canceled checks, and other supporting documentation; and (3) recalculate and compare fund balance with amounts recorded in the general journal and Schedule of Receipts, Disbursements, and Fund Balance for 2002 and 2001. We were not engaged to perform, and did not perform, an examination, the objective of which would have been to express an opinion on the amounts reported on the schedules. Accordingly, we do not express such an opinion. Had we performed additional procedures, other matters might have come to our attention that we would have reported them."

Novel imaging techniques, integrated with mineralogical, geochemical and microbiological characterizations to determine the biogeochemical controls on technetium mobility in FRC sediments

The objective of this research program was to take a highly multidisciplinary approach to define the biogeochemical factors that control technetium (Tc) mobility in FRC sediments. The aim was to use batch and column studies to probe the biogeochemical conditions that control the mobility of Tc at the FRC. Background sediment samples from Area 2 (pH 6.5, low nitrate, low {sup 99}Tc) and Area 3 (pH 3.5, high nitrate, relatively high {sup 99}Tc) of the FRC were selected (http://www.esd.ornl.gov/nabirfrc). For the batch experiments, sediments were mixed with simulated groundwater, modeled on chemical constituents of FRC waters and supplemented with {sup 99}Tc(VII), both with and without added electron donor (acetate). The solubility of the Tc was monitored, alongside other biogeochemical markers (nitrate, nitrite, Fe(II), sulfate, acetate, pH, Eh) as the 'microcosms' aged. At key points, the microbial communities were also profiled using both cultivation-dependent and molecular techniques, and results correlated with the geochemical conditions in the sediments. The mineral phases present in the sediments were also characterized, and the solid phase associations of the Tc determined using sequential extraction and synchrotron techniques. In addition to the batch sediment experiments, where discrete microbial communities with the potential to reduce and precipitate {sup …

Haloarchaeal Protein Translocation via the Twin Arginine Translocation Pathway

Protein transport across hydrophobic membranes that partition cellular compartments is essential in all cells. The twin arginine translocation (Tat) pathway transports proteins across the prokaryotic cytoplasmic membranes. Distinct from the universally conserved Sec pathway, which secretes unfolded proteins, the Tat machinery is unique in that it secretes proteins in a folded conformation, making it an attractive pathway for the transport and secretion of heterologously expressed proteins that are Sec-incompatible. During the past 7 years, the DOE-supported project has focused on the characterization of the diversity of bacterial and archaeal Tat substrates as well as on the characterization of the Tat pathway of a model archaeon, Haloferax volcanii, a member of the haloarchaea. We have demonstrated that H. volcanii uses this pathway to transport most of its secretome.

U.S. Department of Energy Consequence Management Under the National Response Framework

Under the Nuclear/Radiological Incident Annex of the National Response Framework, the U.S. Department of Energy (DOE) has specific responsibilities as a coordinating agency and for leading interagency response elements in the Federal Radiological Monitoring and Assessment Center (FRMAC). Emergency response planning focuses on rapidly providing response elements in stages after being notified of a nuclear/radiological incident. The use of Home Teams during the field team deployment period and recent advances in collecting and transmitting data from the field directly to assessment assets has greatly improved incident assessment times for public protection decisions. The DOE’s Remote Sensing Laboratory (RSL) based in Las Vegas, Nevada, has successfully deployed technical and logistical support for this mission at national exercises such as Top Officials Exercise IV (TOPOFF IV). In a unique response situation, DOE will provide advance contingency support to NASA during the scheduled launch in the fall of 2009 of the Mars Science Laboratory (MSL). The MSL rover will carry a radioisotope power system that generates electricity from the heat of plutonium’s radioactive decay. DOE assets and contingency planning will provide a pre-incident response posture for rapid early plume phase assessment in the highly unlikely launch anomaly.

Plant Mounds as Concentration and Stabilization Agents for Actinide Soil Contaminants in Nevada

Plant mounds or blow-sand mounds are accumulations of soil particles and plant debris around the base of shrubs and are common features in deserts in the southwestern United States. An important factor in their formation is that shrubs create surface roughness that causes wind-suspended particles to be deposited and resist further suspension. Shrub mounds occur in some plant communities on the Nevada Test Site, the Nevada Test and Training Range (NTTR), and Tonopah Test Range (TTR), including areas of surface soil contamination from past nuclear testing. In the 1970s as part of early studies to understand properties of actinides in the environment, the Nevada Applied Ecology Group (NAEG) examined the accumulation of isotopes of Pu, 241Am, and U in plant mounds at safety experiment and storage-transportation test sites of nuclear devices. Although aerial concentrations of these contaminants were highest in the intershrub or desert pavement areas, the concentration in mounds were higher than in equal volumes of intershrub or desert pavement soil. The NAEG studies found the ratio of contaminant concentration of actinides in soil to be greater (1.6 to 2.0) in shrub mounds than in the surrounding areas of desert pavement. At Project 57 on the NTTR, 17 percent …

Science and Technology of Future Light Sources: A White Paper

Many of the important challenges facing humanity, including developing alternative sources of energy and improving health, are being addressed by advances that demand the improved understanding and control of matter. While the visualization, exploration, and manipulation of macroscopic matter have long been technological goals, scientific developments in the twentieth century have focused attention on understanding matter on the atomic scale through the underlying framework of quantum mechanics. Of special interest is matter that consists of natural or artificial nanoscale building blocks defined either by atomic structural arrangements or by electron or spin formations created by collective correlation effects (Figure 1.1). The essence of the challenge to the scientific community has been expressed in five grand challenges for directing matter and energy recently formulated by the Basic Energy Sciences Advisory Committee [1]. These challenges focus on increasing our understanding of, and ultimately control of, matter at the level of atoms, electrons. and spins, as illustrated in Figure 1.1, and serve the entire range of science from advanced materials to life sciences. Meeting these challenges will require new tools that extend our reach into regions of higher spatial, temporal, and energy resolution. X-rays with energies above 10 keV offer capabilities extending beyond …

U.S. Department of Energy Consequence Management Under the National Response Framework

Dramatic advances in data management have been made as a result of the Paperless FRMAC initiative, sponsored by the DOE’s Office of Emergency Response (NA-42). The FRMAC (Federal Radiological Monitoring and Assessment Center) is the hub for all radiological monitoring and the production of data products that interpret those measurements in terms of protective action guidelines. As such, very large amounts of data must be quickly assimilated from numerous sources and then widely distributed as graphical interpretations as fast as possible. Paperless FRMAC is a broad initiative to move that data faster, farther and better through telemetry, automation, and networking. This discussion reviews for the first time the status of the now two-year-old Paperless FRMAC initiative. Key features of Paperless FRMAC include multipath telemetry of measurements from DOE field teams, 24/7 Internet presence, early data entry by first responders, support for distance collaborations, and data exchange with the EPA’s SCRIBE database. The heart of the enterprise is the RAMS database, which provides seamless interfacing with GIS, LIMS, and TurboFRMAC for calculations. Paperless FRMAC is presented to users via two Internet websites. The first, FRMAC Portal website, is restricted to the emergency responders for data input, analysis, and product development. The …
