Environmental Justice: EPA Needs to Take Additional Actions to Help Ensure Effective Implementation (open access)

Environmental Justice: EPA Needs to Take Additional Actions to Help Ensure Effective Implementation

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) is responsible for promoting environmental justice--that is, the fair treatment and meaningful involvement of all people in developing, implementing, and enforcing environmental laws, regulations, and policies. In January 2010, the EPA Administrator cited environmental justice as a top priority for the agency. GAO was asked to examine (1) how EPA is implementing its environmental justice efforts, and (2) the extent that EPA has followed leading federal strategic planning practices in establishing a framework for these efforts. To conduct this work, GAO reviewed EPA strategy documents and interviewed agency officials and key stakeholders."

Suspension and Debarment: Some Agency Programs Need Greater Attention, and Governmentwide Oversight Could Be Improved (open access)

Suspension and Debarment: Some Agency Programs Need Greater Attention, and Governmentwide Oversight Could Be Improved

A publication issued by the Government Accountability Office with an abstract that begins "This testimony discusses the Federal government's use of suspensions and debarments. In 2010, spending on contracted goods and services was more than $535 billion. To protect the government's interests, federal agencies are required to award contracts only to responsible sources--those that are determined to be reliable, dependable, and capable of performing required work. One way to do so is through the use of suspensions and debarments, which are actions taken to exclude firms or individuals from receiving contracts or assistance based on various types of misconduct. The Federal Acquisition Regulation (FAR) prescribes overall policies and procedures governing the suspension and debarment of contractors by agencies and directs agencies to establish appropriate procedures to implement them. This flexibility enables each agency to establish a suspension and debarment program suitable to its mission and structure. Even though the FAR specifies numerous causes for suspensions and debarments, including fraud, theft, bribery, tax evasion, or lack of business integrity, the existence of one of these does not necessarily require that the party be suspended or debarred. Agencies are to establish procedures for prompt reporting, investigation, and referral to the agency suspension …

Business Systems Modernization: Internal Revenue Service's Fiscal Year 2011 Expenditure Plan (open access)

Business Systems Modernization: Internal Revenue Service's Fiscal Year 2011 Expenditure Plan

A publication issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) Business Systems Modernization (BSM) program is a multi-billion dollar, high-risk, highly complex effort that involves the development and delivery of a number of modernized systems that are intended to replace the agency's aging business and tax processing systems. As required, IRS submitted its fiscal year 2011 expenditure plan in May 2011 to the House and Senate appropriations committees, requesting approximately $352 million from the BSM account. In response to a mandate, GAO's objectives in reviewing the expenditure plan were to (1) determine whether it satisfies the applicable statutory conditions, (2) determine IRS's progress in implementing prior expenditure plan review recommendations, and (3) provide additional observations about the plan and the BSM program. To accomplish the objectives, GAO analyzed the plan, reviewed related documentation, and interviewed IRS officials."

EPA Health Risk Assessments: Oversight and Sustained Management Key to Overcoming Challenges (open access)

EPA Health Risk Assessments: Oversight and Sustained Management Key to Overcoming Challenges

A publication issued by the Government Accountability Office with an abstract that begins "This testimony discusses our prior work on the Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) program and database. IRIS is one of the most significant tools that EPA has developed to support its mission to protect people and the environment from harmful chemical exposures. The IRIS database contains EPA's scientific position on the potential human health effects that may result from exposure to more than 550 chemicals in the environment and is a critical component of EPA's capacity to support its mission. IRIS assessments provide the scientific input to risk management decisions, such as whether EPA should establish air and water quality standards to protect the public from exposure to toxic chemicals or set cleanup standards for hazardous waste sites. Consequently, IRIS assessments are a critical component of EPA's capacity to support scientifically sound decisions, policies, and regulations. EPA created IRIS in 1985 to help the agency develop consensus opinions within the agency about the health effects from chronic exposure to chemicals. Over time, the importance of the program has increased as EPA program offices, state and local environmental programs, and some international regulatory bodies …

DOD and VA Health Care: Action Needed to Strengthen Integration across Care Coordination and Case Management Programs

A publication issued by the Government Accountability Office with an abstract that begins "In a May 2011 testimony before this subcommittee (GAO-11-572T), based on a March 2011 report (GAO-11-250), GAO highlighted challenges for the Federal Recovery Coordination Program (FRCP), developed by the Departments of Defense (DOD) and Veterans Affairs (VA) to assist some of the most severely wounded, ill, and injured servicemembers, veterans, and their families. Specifically, GAO reported on challenges in FRCP enrollment, staffing needs, caseloads, and placement locations. GAO also cited challenges faced by the FRCP when coordinating with other VA and DOD programs, including DOD's Recovery Coordination Program (RCP), which can result in duplication of effort and enrollee confusion. In this statement, GAO examines the status of DOD and VA's efforts to (1) implement GAO's March 2011 recommendations and (2) identify and analyze potential options to functionally integrate the FRCP and RCP. This statement is based on GAO's March 2011 report and updated information obtained in September 2011."

ESG-CET Final Progress Title (open access)

ESG-CET Final Progress Title

Drawing to a close after five years of funding from DOE's ASCR and BER program offices, the SciDAC-2 project called the Earth System Grid (ESG) Center for Enabling Technologies has successfully established a new capability for serving data from distributed centers. The system enables users to access, analyze, and visualize data using a globally federated collection of networks, computers and software. The ESG software - now known as the Earth System Grid Federation (ESGF) - has attracted a broad developer base and has been widely adopted so that it is now being utilized in serving the most comprehensive multi-model climate data sets in the world. The system is used to support international climate model intercomparison activities as well as high profile U.S. DOE, NOAA, NASA, and NSF projects. It currently provides more than 25,000 users access to more than half a petabyte of climate data (from models and from observations) and has enabled over a 1,000 scientific publications.

Electron beam loss assumptions for ELI-NPMEGa-ray radioprotection analysis (open access)

Electron beam loss assumptions for ELI-NPMEGa-ray radioprotection analysis

The ELI-NP project is now working on the design of their conventional facility. Dr. Gheorghe Cata-Danil recently requested that I provide them with information on the location and amount of electron-beam loss in the MEGa-ray source they have proposed for ELI-NP. This memo is intended to document that information, for transmission to ELI-NP. The ELI-NP MEGa-ray source, as presently proposed, consists of two x-band accelerator sections separated by a large chicane, as show in figure 1. The basic parameters of the machine that are pertinent for specifying the radiation source terms are shown in table 1. These are the parameters of the intentionall-produced photobeam. In addition to the photobeam, the electron gun and accelerator will produce 'dark current' that originates throughout the RF structures (that is, distributed along the accelerator axis) and therefore has a distribution of energy below the energy of the photobeam. Because it is emitted from surfaces inside the RF structures, much of it is not transported through the accelerator and is lost in the accelerator RF structures. A large fraction of the total dark current is produced in the photogun and lost at the entrance of the 1st accelerator RF structure. Important sources of radiation during …

DETERMINATION OF HLW GLASS MELT RATE USING X-RAY COMPUTED TOMOGRAPHY (open access)

DETERMINATION OF HLW GLASS MELT RATE USING X-RAY COMPUTED TOMOGRAPHY

The purpose of the high-level waste (HLW) glass melt rate study is two-fold: (1) to gain a better understanding of the impact of feed chemistry on melt rate through bench-scale testing, and (2) to develop a predictive tool for melt rate in support of the on-going frit development efforts for the Defense Waste Processing Facility (DWPF). In particular, the focus is on predicting relative melt rates, not the absolute melt rates, of various HLW glass formulations solely based on feed chemistry, i.e., the chemistry of both waste and glass-forming frit for DWPF. Critical to the successful melt rate modeling is the accurate determination of the melting rates of various HLW glass formulations. The baseline procedure being used at the Savannah River National Laboratory (SRNL) is to; (1) heat a 4 inch-diameter stainless steel beaker containing a mixture of dried sludge and frit in a furnace for a preset period of time, (2) section the cooled beaker along its diameter, and (3) measure the average glass height across the sectioned face using a ruler. As illustrated in Figure 1-1, the glass height is measured for each of the 16 horizontal segments up to the red lines where relatively large-sized bubbles begin …

US Renewable Futures in the GCAM (open access)

US Renewable Futures in the GCAM

This project examines renewable energy deployment in the United States using a version of the GCAM integrated assessment model with detailed a representation of renewables, the GCAM-RE. Electricity generation was modeled in four generation segments and 12-subregions. This level of regional and sectoral detail allows a more explicit representation of renewable energy generation. Wind, solar thermal power, and central solar PV plants are implemented in explicit resource classes with new intermittency parameterizations appropriate for each technology. A scenario analysis examines a range of assumptions for technology characteristics, climate policy, and long-distance transmission. We find that renewable generation levels grow over the century in all scenarios. As expected, renewable generation increases with lower renewable technology costs, more stringent climate policy, and if alternative low-carbon technology are not available. The availability of long distance transmission lowers policy costs and changes the renewable generation mix.

Direct observation of two-step crystallization in nanoparticle superlattice formation (open access)

Direct observation of two-step crystallization in nanoparticle superlattice formation

Direct imaging of nanoparticle solutions by liquid phase transmission electron microscopy has enabled unique in-situ studies of nanoparticle motion and growth. In the present work, we report on real-time formation of two-dimensional nanoparticle arrays in the very low diffusive limit, where nanoparticles are mainly driven by capillary forces and solvent fluctuations. We find that superlattice formation appears to be segregated into multiple regimes. Initially, the solvent front drags the nanoparticles, condensing them into an amorphous agglomerate. Subsequently, the nanoparticle crystallization into an array is driven by local fluctuations. Following the crystallization event, superlattice growth can also occur via the addition of individual nanoparticles drawn from outlying regions by different solvent fronts. The dragging mechanism is consistent with simulations based on a coarse-grained lattice gas model at the same limit.
