  5. EPA Hearing Sparks Controversy

    NASA Astrophysics Data System (ADS)

    Zielinski, Sarah

    2006-03-01

    The U.S. Environmental Protection Agency (EPA) is not investing enough money in the science needed for the agency to make sound environmental policy decisions, according to several witnesses who testified before a U.S. House of Representatives subcommittee on 16 March. The House Science Subcommittee on Environment, Technology, and Standards brought together George Gray, EPA associate administrator for research and development, and three other witnesses to discuss the proposed cuts to EPA's Office of Research and Development (ORD), the agency's primary research arm. The Bush Administration has proposed cutting the ORD budget by six percent in Fiscal Year 2007, to $557 million. This would continue a trend of decreases for ORD, whose budget would decline by 14 percent from FY2004 to FY2007 if the cuts are approved by the U.S. Congress.

  14. A new proof of tractability for ORD-horn relations

    SciTech Connect

    Ligozat, G.

    1996-12-31

    This paper gives an elementary proof of the tractability of a sub-class of temporal relations in Allen`s algebra and related temporal calculi, the class of pre-convex relations. In Allen`s case, this subclass coincides with the class of ORD-Horn relations. Nebel and Burckert defined ORD-Horn relations and proved that path-consistency is a sufficient condition for consistency of a network for this sub-class. We prove a stronger result: for each path-consistent network in the sub-class, we give an effective method for constructing a feasible scenario without backtrack.

  10. The identity of the enigmatic "Black Shrew" (Sorex niger Ord, 1815)

    USGS Publications Warehouse

    Woodman, Neal

    2013-01-01

    The scientific name Sorex niger Ord, 1815 (Mammalia, Soricidae) was originally applied to a North American species that George Ord called the “Black Shrew.” The origin of the name “Black Shrew,” however, was obscure, and Samuel Rhoads subsequently wrote that the species represented by this name could not be determined. The names Sorex niger Ord and Black Shrew have since been mostly forgotten. Two of Ord's contemporaries, however, noted that Ord's use of these names probably alluded to Benjamin Smith Barton's Black Shrew, whose discovery near Philadelphia was announced by Barton in 1806. Examination of two unpublished illustrations of the Black Shrew made by Barton indicates that the animal depicted is Blarina brevicauda (Say, 1822). Had the connection between Ord's and Barton's names been made more clearly, one of the most common mammals in eastern North America would bear a different scientific name today. This connection also would have affected the validity of Sorex niger Horsfield, 1851. While Sorex niger Ord remains a nomen nudum, the animal it referenced can now be identified.

  11. EPA risk management update

    SciTech Connect

    Mentzer, W.P.

    1995-09-01

    The US Environmental Protection Agency (EPA) Clean Air Act (CAA) was passed in 1970 with amendments added in 1970 and 1990. The 1990 amendments require the EPA to develop regulations to prevent or mitigate chemical accidents that could affect the public and the environment. The regulation is the EPA`s Risk Management Programs (RMP) for Chemical Accidental Release Prevention and was published as proposed rule 40 CFR 68. The RMP is similar to OSHA`s Process Safety Management standard which became effective on May 26, 1992. The EPA`s Risk Management Program deals with 77 toxic chemicals, 63 flammable gases and liquids and certain explosives used at 122,000 work sites. The key elements of the RMP include: registration; hazard assessment; prevention program; emergency response; risk management plan; auditing; and enforcement. The Sierra Club sued the EPA to obtain a court-ordered deadline for promulgation of the final RMP rule. The Oct. 1994 court-approved settlement permitted the EPA to issue a supplemental rulemaking notice and set March 29, 1996, as the deadline for the final RMP rule. The supplemental rulemaking notice, issued by the EPA on March 2, 1995, presents preferred approaches to several key issues in the RMP. The presentation will cover the evolution of the EPA-CAAA-RMP, the requirements of the RMP and the significant changes resulting from the supplemental rulemaking.

  18. EPA`s clean air power initiative

    SciTech Connect

    Critchfield, L.R.

    1997-12-31

    The Clean Air Power Initiative (CAPI) is a multi-stakeholder project intended to improve air pollution control efforts involving the power generating industry. This paper documents the progress made in the first year of the initiative, which included a number of meetings with interested stakeholders and development and analysis of alternative approaches for more efficient and effective pollution control. The project`s goal is to develop an integrated regulatory strategy or three major pollutants emitted from electric power generators; namely, sulfur dioxide, nitrogen oxides, and, potentially, mercury. Major reductions in these pollutants are expected to be needed to reduce the detrimental health effects of ground-level ozone, fine particles, and hazardous air pollutants and reduce the environmental effects of acidification, eutrophication, ecosystem, crop, and materials damage, and regional haze. The Clean Air Power Initiative has considered, where feasible, new approaches to pollution control that recognize the long-range transport of many air pollutants and the economic benefits of emissions trading. The project was initiated by EPA`s Assistant Administrator for Air and Radiation in 1995. As individual companies develop and implement strategies to participate in more competitive power markets, they could benefit from greater certainty in being able to plan for and reduce costs of future environmental regulations. The EPA is interested in reinventing its regulatory approach to reduce the number, administrative complexity, and cost of its requirements while improving the likelihood of achieving environmental results.

    1989-01-01

    The Electrostatic Plasma Accelerator (EPA) is a thruster concept which promises specific impulse levels between low power arcjets and those of the ion engine while retaining the relative simplicity of the arcjet. The EPA thruster produces thrust through the electrostatic acceleration of a moderately dense plasma. No accelerating electrodes are used and the specific impulse is a direct function of the applied discharge voltage and the propellant atomic mass. The goal of the present program is to demonstrate feasibility of the EPA thruster concept through experimental and theoretical investigations of the EPA acceleration mechanism and discharge chamber performance. Experimental investigations will include operating the test bed ion (TBI) engine as an EPA thruster and parametrically varying the thruster geometry and operating conditions to quantify the electrostatic plasma acceleration effect. The theoretical investigations will include the development of a discharge chamber model which describes the relationships between the engine size, plasma properties, and overall performance. For the EPA thruster to be a viable propulsion concept, overall thruster efficiencies approaching 30% with specific impulses approaching 1000 s must be achieved.

  4. EPA`s integrated nitrogen oxides strategy

    SciTech Connect

    Grano, D.H.

    1997-12-31

    Nitrogen oxides (NO{sub x}) are highly reactive and play a major role in the formation of various gases and particles in the atmosphere which lead to harmful effects on human health and welfare. This paper briefly describes the multiple impacts on human health and welfare that result from emissions of NO{sub x} and describes EPA`s strategy to integrate NO{sub x} reductions from various mobile and stationary sources in a balanced manner to achieve environmental benefits. Based on modeling information, it is clear that substantial reductions in NO{sub x} emissions over large geographic areas are needed if many densely populated areas of the nation are to attain the national ambient air quality standard for ozone. In addition to attainment of the health standard for ozone, the reduction of NO{sub x} emissions will also likely improve the nation`s environment by reducing adverse impacts of acid deposition, eutrophication of waterbodies, global warming, nitrogen dioxide, particulate matter, stratospheric ozone depletion, toxics, and visibility.

    SciTech Connect

    Cavallaro, A.

    2006-11-15

    The US Environmental Protection Agency (EPA) announced its adjustments to the national air quality standards in late September after a mandatory five-year review process. The National Ambient Air Quality Standards (NAAQS) address fine and coarse particle pollution, also known as particulate matter (PM). The final action changes the 24-hour allowance for fine particulates, such as those emitted from coal-fired generation stacks, from 65 micrograms of particles per cubic meter of air to 35 {mu}g/m{sup 3}. EPA said this measure protects people from short-term exposure to fine particles. The annual standard will remain the same at 15 {mu}g/m{sup 3}. Carl Weilert of Burns and McDonnell gave some comments on implications of the standards in an interview with Power Engineering. 1 ref.

    NASA Technical Reports Server (NTRS)

    Brophy, John R.; Aston, Graeme

    1995-01-01

    The application of electric propulsion to communications satellites, however, has been limited to the use of hydrazine thrusters with electric heaters for thrust and specific impulse augmentation. These electrothermal thrusters operate at specific impulse levels of approximately 300 s with heater powers of about 500 W. Low power arcjets (1-3 kW) are currently being investigated as a way to increase specific impulse levels to approximately 500 s. Ion propulsion systems can easily produce specific impulses of 3000 s or greater, but have yet to be applied to communications satellites. The reasons most often given for not using ion propulsion systems are their high level of overall complexity, low thrust with long burn times, and the difficulty of integrating the propulsion system into existing commercial spacecraft busses. The Electrostatic Plasma Accelerator (EPA) is a thruster concept which promises specific impulse levels between low power arcjets and those of the ion engine while retaining the relative simplicity of the arcjet. The EPA thruster produces thrust through the electrostatic acceleration of a moderately dense plasma. No accelerating electrodes are used and the specific impulse is a direct function of the applied discharge voltage and the propellant atomic mass.

    1975-01-01

    The proposed ERTS-DCS system is designed to allow EPA the capability to evaluate, through demonstrable hardware, the effectiveness of automated data collection techniques. The total effectiveness of any system is dependent upon many factors which include equipment cost, installation, maintainability, logistic support, growth potential, flexibility and failure rate. This can best be accomplished by installing the system at an operational environmental control agency (CAMP station) to insure that valid data is being obtained and processed. Consequently, it is imperative that the equipment interface must not compromise the validity of the sensor data nor should the experimental system effect the present operations of the CAMP station. Since both the system which is presently in use and the automatic system would be in operation in parallel, conformation and comparison are readily obtained.

    Haines, Seth S.; Burton, Bethany L.; Hunter, Lewis E.

    2007-01-01

    At the former Fort Ord in Monterey County, California, contamination threatens an aquifer that provides drinking water for local communities. Assessment and remediation require accurate hydrological modeling, which in turn require a thorough understanding of aquifer stratigraphy. In order to help guide remediation efforts at the site, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, has undertaken seismic reflection surveys, testing compressional (P) and horizontally polarized shear (SH) waves. Sledgehammer-source SH data show reflections from interfaces up to approximately 60 m deep, which correspond with the major boundaries between aquifers and aquitards. In contrast, P-wave data show only the reflection from the water table at approximately 30 m depth. We collected SH data along two transects and processed these data to produce reflection images. The interpreted SH-wave images agree with available well information, constrain the geology for ground-water models, and provide guidance for future geophysical studies. These favorable results demonstrate the effectiveness of SH reflection methods for imaging unconsolidated aquifer layers at the former Fort Ord and at other sites with similar geologic conditions.

  13. ord1, an oxidoreductase gene responsible for conversion of O-methylsterigmatocystin to aflatoxin in Aspergillus flavus.

    Prieto, R; Woloshuk, C P

    1997-01-01

    Among the enzymatic steps in the aflatoxin biosynthetic pathway, the conversion of O-methylsterigmatocystin to aflatoxin has been proposed to be catalyzed by an oxidoreductase. Transformants of Aspergillus flavus 649WAF2 containing a 3.3-kb genomic DNA fragment and the aflatoxin biosynthesis regulatory gene aflR converted exogenously supplied O-methylsterigmatocystin to aflatoxin B1. A gene, ord1, corresponding to a transcript of about 2 kb was identified within the 3.3-kb DNA fragment. The promoter region presented a putative AFLR binding site and a TATA sequence. The nucleotide sequence of the gene revealed an open reading frame encoding a protein of 528 amino acids with a deduced molecular mass of 60.2 kDa. The gene contained six introns and seven exons. Heterologous expression of the ord1 open reading frame under the transcriptional control of the Saccharomyces cerevisiae galactose-inducible gal1 promoter results in the ability to convert O-methylsterigmatocystin to aflatoxin B1. The data indicate that ord1 is sufficient to accomplish the last step of the aflatoxin biosynthetic pathway. A search of various databases for similarity indicated that ord1 encodes a cytochrome P-450-type monooxygenase, and the gene has been assigned to a new P-450 gene family named CYP64. PMID:9143099

  14. Ord's kangaroo rats living in floodplain habitats: Factors contributing to habitat attraction

    USGS Publications Warehouse

    Miller, M.S.; Wilson, K.R.; Andersen, D.C.

    2003-01-01

    High densities of an aridland granivore, Ord's kangaroo rat (Dipodomys ordii), have been documented in floodplain habitats along the Yampa River in northwestern Colorado. Despite a high probability of inundation and attendant high mortality during the spring flood period, the habitat is consistently recolonized. To understand factors that potentially make riparian habitats attractive to D. ordii, we compared density and spatial pattern of seeds, density of a competitor (western harvester ant, Pogonomyrmex occidentalis), and digging energetics within floodplain habitats and between floodplain and adjacent upland habitats. Seed density within the floodplain was greatest in the topographically high (rarely flooded) floodplain and lowest immediately after a spring flood in the topographically low (frequently flooded) floodplain. Seed densities in adjacent upland habitat that never floods were higher than the lowest floodplain habitat. In the low floodplain prior to flooding, seeds had a clumped spatial pattern, which D. ordii is adept at exploiting; after spring flooding, a more random pattern resulted. Populations of the western harvester ant were low in the floodplain relative to the upland. Digging by D. ordii was energetically less expensive in floodplain areas than in upland areas. Despite the potential for mortality due to annual spring flooding, the combination of less competition from harvester ants and lower energetic costs of digging might promote the use of floodplain habitat by D. ordii.

  20. Dispersal and Germination Patterns of Monterey Spineflower at Fort Ord Natural Reserve.

    NASA Astrophysics Data System (ADS)

    Chaudhry, Z.

    2014-12-01

    Some species are rare because they are restricted to certain habitats and/or have small population sizes. Monterey spineflower, a federally listed threatened annual plant, is found in open sandy regions of the California coast, in chaparral vegetation around the Monterey Bay. A model based on previous research suggests that the Monterey spineflower population at Fort Ord Natural Reserve should be rapidly increasing, but it is not. This suggests that the model may be using data that overestimates the percentage of spineflower seeds that successfully germinate. I tested three hypotheses to determine the cause of the difference in population sizes between the predicted model and the field results. First, I predicted that the spineflower seeds are blown by the wind into shrubs such as manzanita, and are unable to germinate due to the lack of a suitable environment. I tested this in two ways. A field experiment showed that seeds are easily blow by wind. Next, I took soil cores and found spineflower seeds within the manzanita shrubs. Secondly, I predicted that the germination rate used by the model (90%) was too high. However, my germination experiments did not support this hypothesis because 91% of new seeds successfully germinated. Lastly, I predicted that the newer seeds are more viable than older seeds and therefore have a higher chance of successfully germinating. After germinating seeds in a controlled environment I observed that the seeds from 2014 had a higher number of successfully germinated seeds compared to the number of successfully germinated seeds from 1995 (91% vs 33%). I conclude that the loss of seeds due to wind decreases germination expectancies and older seeds are less viable than new seeds. Therefore, Monterey spineflower is a rare plant because environmental barriers hinder seeds from dispersing to a suitable habitat and successfully germinating while seeds lose viability as they age.

    2009-12-01

    The Remote Sensing Information Gateway was developed by the U.S. Environmental Protection Agency (EPA) to assist researchers in easily obtaining and combining a variety of environmental datasets related to air quality research. Current datasets available include, but are not limited to surface PM2.5 and O3 data, satellite derived aerosol optical depth , and 3-dimensional output from U.S. EPA's Models 3/Community Multi-scale Air Quality (CMAQ) modeling system. The presentation will include a demonstration that illustrates several scenarios of how researchers use the tool to help them visualize and obtain data for their work; with a particular focus on episode analysis related to biomass burning impacts on air quality. The presentation will provide an overview on how RSIG works and how the code has been—and can be—adapted for other projects. One example is the Virtual Estuary, which focuses on automating the retrieval and pre-processing of a variety of data needed for estuarine research. RSIG’s source codes are freely available to researchers with permission from the EPA principal investigator, Dr. Jim Szykman. RSIG is available to the community and can be accessed online at http://www.epa.gov/rsig. Once the JAVA policy file is configured on your computer you can run the RSIG applet on your computer and connect to the RSIG server to visualize and retrieve available data sets. The applet allows the user to specify the temporal/spatial areas of interest, and the types of data to retrieve. The applet then communicates with RSIG subsetter codes located on the data owners’ remote servers; the subsetter codes assemble and transfer via ordinary Internet protocols only the specified data to the researcher’s computer.

    Dourson, M.L.

    1990-12-31

    The quantitative procedures associated with noncancer risk assessment include reference dose (RfD), benchmark dose, and severity modeling. The RfD, which is part of the EPA risk assessment guidelines, is an estimation of a level that is likely to be without any health risk to sensitive individuals. The RfD requires two major judgments: the first is choice of a critical effect(s) and its No Observed Adverse Effect Level (NOAEL); the second judgment is choice of an uncertainty factor. This paper discusses major assumptions and limitations of the RfD model.

    Lead is a cumulative poison that is especially hazardous to children. It affects the nervous and reproductive systems by causing neurological and physical development delays, as well as cognitive and behavioral changes. It can also cause hypertension in adults. Lead can be absorbed into the blood by ingestion or inhalation. The author discusses legislative efforts to control lead exposure to humans. They are: Title 10, which amends TSCA; and Title 4 -- Lead Exposure Reduction. The major tasks being performed by EPA to control the exposure of lead to man are included. Professional training is of major importance in this effort.

  11. Intercomparison of Groundwater Flow Monitoring Technologies at Site OU 1, Former Fort Ord, California

    This report presents an intercomparison of three groundwater flow monitoring technologies at a trichloroethylene (TCE) groundwater plume at Operational Unit 1 (OU 1) adjacent to the former Fritzsche Army Airfield at the former Fort Ord Army Base, located on Monterey Bay in northern Monterey County, California. Soil and groundwater at this site became contaminated by fuels and solvents that were burned on a portion of OU 1 called the Fire Drill Area (FDA) as part of firefighter training from 1962 and 1985. Cont Contamination is believed to be restricted to the unconfined A-aquifer, where water is reached at a depth of approximately 60 to 80 feet below the ground surface; the aquifer is from 15 to 20 feet in thickness, and is bounded below by a dense clay layer, the Salinas Valley Aquitard. Soil excavation and bioremediation were initiated at the site of fire training activities in the late 1980s. Since that time a pump-and-treat operation has been operated close to the original area of contamination, and this system has been largely successful at reducing groundwater contamination in this source area. However, a trichloroethylene (TCE) groundwater plume extends approximately 3000 ft (900 m) to the northwest away from the FDA. In this report, we have augmented flow monitoring equipment permanently installed in an earlier project (Oldenburg et al., 2002) with two additional flow monitoring devices that could be deployed in existing monitoring wells, in an effort to better understand their performance in a nearly ideal, homogeneous sand aquifer, that we expected would exhibit laminar groundwater flow owing to the site's relatively simple hydrogeology. The three flow monitoring tools were the Hydrotechnics{reg_sign} In In-Situ Permeable Flow Sensor (ISPFS), the RAS Integrated Subsurface Evaluation Hydrophysical Logging tool (HPL), and the Lawrence Livermore National Laboratory Scanning Colloidal Borescope Flow Meter (SCBFM). All three devices produce groundwater flow

    During field study of Ord's kangaroo rat (Dipodomys ordii) at Suffield National Wildlife Area, Alberta, Canada, a high prevalence of parasitism by botfly (Diptera: Oestridae) larvae was observed. Botflies have not previously been documented as parasites of kangaroo rats. Botfly parasitism could have a significant impact on the growth, survival, and reproduction of Ord's kangaroo rat, which is considered a vulnerable species in Canada. Therefore, it is important to investigate how botfly parasitism varies with season and with gender or age of host. In 1995, 525 individual kangaroo rats were caught by nightlighting and live trapping for a total of 952 capture records. Upon capture, each kangaroo rat was ear-tagged and thoroughly examined for parasites and wounds. Third-instar botfly (Cuterebra polita) larvae were observed in kangaroo rats between 16 June and 23 August. Prevalence was 34% based on 454 kangaroo rats sampled during that time, whereas the mean intensity was 2.3 larvae per infested host (n = 156, range = 1-11). In contrast to some other studies of botfly parasitism of rodents, there were no gender or age biases in either prevalence or intensity of infestation. The index of dispersion was 2.8, indicating that the parasites were aggregated in hosts. Botfly parasitism could be an important factor affecting northern populations of kangaroo rats; future investigations into the potential effects of botfly larvae on host fitness are warranted.

    Narratives of the experience of pulmonary tuberculosis (TB) are relatively rare in the Irish context. A scourge of the early twentieth century, TB was as much a social as a physically debilitating disease that rendered sufferers silent about their experience. Thus, the personal diaries and letters of Irish poet, Seán Ó Ríordáin, (1916-1977) are rare. This article presents translations of his personal papers in a historico-medical context to chronicle Ó Ríordáin's experience of a life marred by respiratory disease. Familiar to generations of schoolchildren are his imaginative poems, whose lively metre punctuated the Irish language curriculum from primary through to secondary schooling; for most they leave an indelible mark. Such buoyant poems however belie the reality of his existence, lived in the shadow of chronic illness, and punctuated with despair over his condition and anxiety about the periods of extended sick leave his illness necessitated. Although despair dominated his diaries and he routinely begged God, Mary, the Saints and the devil for death, they were also the locus where his creativity developed. In his diaries, caricatures of friends and sketches of everyday things nestle among the first lines of some of his most influential poems and quotes from distinguished philosophers and writers. Evocative and tragic, his diaries offer a unique prism to the experience of respiratory disease in Ireland. PMID:24002457

    The proposed Neurotoxicity Risk Assessment Guidelines (U.S. EPA, 1995c Fed. Reg. 60(192), 52032-52056) of the U.S. Environmental Protection Agency (EPA) were the subject of a workshop at the 1997 Meeting of the Society of Toxicology. The workshop considered the role of guidelines in the risk assessment process, the primary features, scientific basis, and implications of the guidelines for EPA program offices, as well as for industrial neurotoxicologists from the perspectives of both pesticides and toxic substances regulation. The U.S. National Academy of Sciences (NAS, 1983, Risk Assessment in the Federal Government: Managing the Process) established a framework for distinguishing risk management from risk assessment, the latter being the result of integrating hazard identification, hazard characterization, and exposure assessment data. The guidelines are intended to establish operating principles that will be used when examining data in a risk assessment context. The proposed neurotoxicity risk assessment guidelines provide a conceptual framework for deciding whether or not a chemically induced effect can be considered to be evidence of neurotoxicity. Topics in the proposed guidelines include structural and functional effects, dose-response and -duration considerations, and relationships between effects. Among the issues that must be considered are the multiplicity of chemical effects, the levels of biological organization in the nervous system, and the tests, measurements, and protocols used. Judgment of the adversity of an effect depends heavily on the amount and types of data available. The attribution of a chemically induced effect to an action on the nervous system depends on several factors such as the quality of the study, the nature of the outcome, dose-response and time-response relationships, and the possible involvement of nonneural factors. The guidelines will also serve as a reference for those conducting neurotoxicity testing, as well as establish a

    A Gram-negative, chemoheterotrophic, facultatively anaerobic coccus, designated IMCC1545(T), was isolated from the digestive tract of a marine clamworm, Periserrula leucophryna, inhabiting a tidal flat of the Yellow Sea. Cells of strain IMCC1545(T) are non-motile, dividing by binary fission. The predominant fatty acids are anteiso-C(15 : 0) and C(18 : 0). The respiratory quinone is menaquinone-7 and the DNA G+C content is 52.1 mol%. Phylogenetic analyses based on 16S rRNA gene sequences using three treeing algorithms revealed that the strain formed a novel genus-level lineage within the phylum 'Verrucomicrobia'. The most closely related named organisms to strain IMCC1545(T) are 'Fucophilus fucoidanolyticus' SI-1234 (86.5 % 16S rRNA gene sequence similarity), Alterococcus agarolyticus ADT3(T) (81.8 %) and Opitutus terrae PB90-1(T) (80.3 %), which belong to subdivision 4 of the 'Verrucomicrobia'. Subdivision 4 of the 'Verrucomicrobia' (here named Opitutae classis nov.) was divided into two clades, a clade containing strain IMCC1545(T) and a clade containing Opitutus terrae. From the taxonomic data obtained in this study, it is proposed that the new marine isolate be placed into a novel genus and species named Puniceicoccus vermicola gen. nov., sp. nov. (the type strain of Puniceicoccus vermicola is IMCC1545(T)=KCCM 42343(T)=NBRC 101964(T)) within Puniceicoccaceae fam. nov and Puniceicoccales ord. nov in the class Opitutae. The family Opitutaceae fam. nov. and order Opitutales ord. nov. are also formally proposed. PMID:17329779

    In a memorandum issued May 13, 1994, Assistant Administrator for Enforcement and Compliance Assurance Steven Herman announced EPA's plans to reassess its current policy regarding environmental auditing and self-evaluation by the regulated community. The memorandum provides encouraging news to industry, which has long asserted that EPA's current auditing policy frustrates, not fosters, critical self-evaluation. EPA states in the memorandum its intention to base its reevaluation of its environmental auditing policies on an empirical approach to ensure that any decision either to reinforce or change existing policies is informed by fact. By the end of this summer, EPA intends to take four actions it believes will be consistent with this general approach.

    2009-01-01

    Various organizations worldwide have made dietary recommendations for eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and fish intake that are primarily for coronary disease risk reduction and triglyceride (TG) lowering. Recommendations also have been made for DHA intake for pregnant women, infants, and vegetarians/vegans. A Dietary Reference Intake (DRI), specifically, an Adequate Intake (AI), has been set for alpha-linolenic acid (ALA) by the Institute of Medicine (IOM) of The National Academies. This amount is based on an intake that supports normal growth and neural development and results in no nutrient deficiency. Although there is no DRI for EPA and DHA, the National Academies have recommended that approximately 10% of the Acceptable Macronutrient Distribution Range (AMDR) for ALA can be consumed as EPA and/or DHA. This recommendation represents current mean intake for EPA and DHA in the United States ( approximately 100mg/day), which is much lower than what many groups worldwide are currently recommending. Global recommendations for long-chain omega-3 fatty acids underscore the pressing need to establish DRIs for DHA and EPA because DRIs are recognized as the "official" standard by which federal agencies issue dietary guidance or policy directives for the health and well-being of individuals in the United States and Canada. Because of the many health benefits of DHA and EPA, it is important and timely that the National Academies establish DRIs for the individual long-chain (20 carbons or greater) omega-3 fatty acids.

    2006-04-03

    The overall objective of this project is the continued development, installation, and testing of continuous water sampling and analysis technologies for application to on-site monitoring of groundwater treatment systems and remediation sites. In a previous project, an on-line analytical system (OLAS) for multistream water sampling was installed at the Fort Ord Operable Unit 2 Groundwater Treatment System, with the objective of developing a simplified analytical method for detection of Compounds of Concern at that plant, and continuous sampling of up to twelve locations in the treatment system, from raw influent waters to treated effluent. Earlier implementations of the water sampling and processing system (Analytical Sampling and Analysis Platform, A A+RT, Milpitas, CA) depended on off-line integrators that produced paper plots of chromatograms, and sent summary tables to a host computer for archiving. We developed a basic LabVIEW (National Instruments, Inc., Austin, TX) based gas chromatography control and data acquisition system that was the foundation for further development and integration with the ASAP system. Advantages of this integration include electronic archiving of all raw chromatographic data, and a flexible programming environment to support development of improved ASAP operation and automated reporting. The initial goals of integrating the preexisting LabVIEW chromatography control system with the ASAP, and demonstration of a simplified, site-specific analytical method were successfully achieved. However, although the principal objective of this system was assembly of an analytical system that would allow plant operators an up-to-the-minute view of the plant's performance, several obstacles remained. Data reduction with the base LabVIEW system was limited to peak detection and simple tabular output, patterned after commercial chromatography integrators, with compound retention times and peak areas.

    Aylward, Michael; Nixon, James; Gladding, Sophia

    2014-10-01

    Medical education is moving toward assessment of educational outcomes rather than educational processes. The American Board of Internal Medicine and American Board of Pediatrics milestones and the concept of entrustable professional activities (EPA)--skills essential to the practice of medicine that educators progressively entrust learners to perform--provide new approaches to assessing outcomes. Although some defined EPAs exist for internal medicine and pediatrics, the continued development and implementation of EPAs remains challenging. As residency programs are expected to begin reporting milestone-based performance, however, they will need examples of how to overcome these challenges. The authors describe a model for the development and implementation of an EPA using the resident handoff as an example. The model includes nine steps: selecting the EPA, determining where skills are practiced and assessed, addressing barriers to assessment, determining components of the EPA, determining needed assessment tools, developing new assessments if needed, determining criteria for advancement through entrustment levels, mapping milestones to the EPA, and faculty development. Following implementation, 78% of interns at the University of Minnesota Medical School were observed giving handoffs and provided feedback. The authors suggest that this model of EPA development--which includes engaging stakeholders, an iterative process to describing the behavioral characteristics of each domain at each level of entrustment, and the development of specific assessment tools that support both formative feedback and summative decisions about entrustment--can serve as a model for EPA development for other clinical skills and specialty areas.

Fuels and solvents were burned on a portion of OU 1 called the Fire Drill Area (FDA) during airport fire suppression training between 1962 and 1985. This activity resulted in soil and groundwater contamination in the unconfined A-aquifer. In the late 1980's, soil excavation and bioremediation were successful in remediating soil contamination at the site. Shortly thereafter, a groundwater pump, treat, and recharge system commenced operation. This system has been largely successful at remediating groundwater contamination at the head of the groundwater plume. However, a trichloroethylene (TCE) groundwater plume extends approximately 3000 ft (900 m) to the northwest away from the FDA. In the analyses presented here, we augment our prior work (Oldenburg et al., 2002) with new information including treatment-system totalizer data, recent water-level and chemistry data, and data collected from new wells to discern trends in contaminant migration and groundwater flow that may be useful for ongoing remediation efforts. Some conclusions from the prior study have been modified based on these new analyses, and these are pointed out clearly in this report.

    Recent studies have shown that EPA enriched PLs have beneficial effects on lipid metabolism. Our previous study has demonstrated that the anti-obesity and hypolipidemic effects of EPA-PL were superior to DHA-PL. In the present study, we comparatively evaluated the effects of EPA-enriched phosphatidylcholine (EPA-PC) and EPA-enriched phosphatidylserine (EPA-PS) on lipid metabolism in mice. Both 2% dietary EPA-PC and EPA-PS significantly improved serum and hepatic lipid levels in mice. The HDL-c level in mice on EPA-PC diet was significantly higher than the other two groups. The level of DHA in hepatic TG and PL were significantly increased in both EPA-PC and EPA-PS fed groups (98.3 and 117.8%, respectively; p < 0.05). Notably, the proportion of DHA in EPA-PS group was significantly higher than the EPA-PC group. EPA-PC and EPA-PS suppressed hepatic SREBP-1c mediated lipogenesis and activated PPARα mediated fatty acid β-oxidation in the liver. These data are the first to indicate that EPA-PS has beneficial effects on lipid metabolism. PMID:27321119

    1982-09-01

    As stated at the beginning of this paper conclusions reached thus far cannot be discussed in this paper. However, a great deal of information is available for examination.EPA displayed its ability to coordinate widely separated laboratories, both Federal and private, into a smooth working team in a very short period of time. A very comprehensive study plan was also developed and implemented quickly. EPA was fortunate to have already had GCA under contract when the emergency arose. In no small part the success of the field effort was due to the managerial and technical abilities of the GCA team.Within a period of 6 weeks a plan was developed, a prime contractor retained, subcontractors hired, and field activities begun. Within a period of 3 months in excess of 8600 field samples were collected and over 12,000 field and QC samples were analyzed. During this same period 2 major data systems were developed, debugged, and placed into operation.In short this EPA project was probably the most comprehensive multimedia field project ever attempted by EPA and certainly the data is being subjected to the most strenuous quality control measures ever imposed by this Agency. The entire program is presently under peer review and the results are being prepared for publication by EPA Headquarters. PMID:24264296

  12. EPA`s plan for part 75 continuous emissions monitoring rule revisions

    1997-12-31

    As a result of on-going internal and external assessment of the Acid Rain Program monitoring and reporting requirements, EPA, state environmental agencies, and utilities have identified areas of the Part 75 CEM regulations which would benefit from revision or clarification. Many of the suggested revisions will add increased flexibility to the utility industry in implementing and complying with the requirements of Part 75. Other revisions will clarify existing provisions in an effort to make the regulation more understandable. Still other revisions will provide increased quality assurance of the Acid Rain Program CEM data. The panel will present EPA`s current plans for a proposed rulemaking to incorporate the technical revisions to Part 75. The panel will briefly discuss EPA`s proposed revisions to some of the major issues and will respond to questions.

  13. EPA clarifies its environmental auditing policy

    1994-10-01

    EPA's audit policy is entitled ''Environmental Auditing Policy Statement.'' EPA's current policy is intended to encourage regulated entities to develop, implement and periodically upgrade environmental auditing programs. The policy outlines the elements EPA believes must be included in an audit program if it is to be effective. These include: Explicit top management support for environmental auditing and commitment to follow up on audit findings; An environmental auditing function independent of auditing activities; Adequate team staffing and auditor training; Explicit audit program objectives, scope, resources and frequency; A process that collects, analyzes, interprets and documents information sufficient to achieve audit objectives. A process that includes specific procedure to prepare promptly candid, clear and appropriate written reports on audit findings, corrective actions and schedules for implementation; and A process that includes quality assurance procedures.

  14. EPA looks to change—Not grow

    NASA Astrophysics Data System (ADS)

    Clinton asked for $7.4 billion for the Environmental Protection Agency in FY 1996—a $138 million (2% increase) over FY 1995. EPA's hallmark, according to the agency, is “not growth, but change,” with its strategic plan The New Generation of Environmental Protection as its signpost. Ecosystem protection, environmental justice, pollution prevention, strong science and data, partnerships, environmental accountability, and reinventing EPA management are its top priorities.Clinton's budget asks for $1.56 billion for the Superfund program, a $131.7 million increase over fiscal year 1995. The budget has $77.3 million, a $7.3 million increase, for the Leaking Underground Storage Tank (LUST) program. EPA's water infrastructure program would take a $404 million hit in FY 1996, down to $2.37 billion.

  15. Bill would bolster science at EPA

    NASA Astrophysics Data System (ADS)

    Showstack, Randy

    Since its establishment in 1970, the U.S. Environmental Protection Agency (EPA) has primarily served as a regulatory agency with a significant science component. However, the agency's scientific practices and performance at times have been criticized by the U.S. General Accounting Office, the National Academies of Science (NAS), Congress, and EPA's own science advisory board, as well as in a number of lawsuits.New legislation introduced by Rep. Vernon Ehlers (R-Mich.), chair of the House of Representatives' Science Subcommittee on Environment, Technology, and Standards, includes measures meant to improve the agency's science component. The legislation, H.R. 64, would require the president to appoint an EPA deputy administrator for science and technology This deputy administrator, who would rank higher than existing assistant administrators (AAs), would be responsible for the overall scientific and technical foundation of the agency's decisions, including ensuring that the agency's scientific endeavors use the best possible peer review and research planning practices.

    Scientific research is one of the most powerful tools we have for understanding and protecting our environment. It provides the foundation for what we know about our planet, how it has changed, and how it could be altered in the future. The National Center for Environmental Research (NCER) in the U.S. Environmental Protection Agency's (EPA) Office of Research and Development (ORD) supports high-quality, extramural research by the nation's leading scientists and engineers to strengthen the basis for decisions about local and national environmental issues. NCER works with academia, state and local governments, other federal agencies, and scientists in EPA to increase human knowledge of how to protect our health and natural resources through its three major programs: · Science to Achieve Results (STAR) Grants · Small Business Innovative Research (SBIR) · Science to Achieve Results (STAR) Fellowships STAR, NCER's primary program, funds research grants and graduate fellowships in environmental science and engineering. Developing the next generation of environmental scientists and engineers is one of NCER's most important objectives. Each year, NCER helps between 80 and 160 students achieve Master's or Ph.D. degrees in environmental science and engineering through its STAR and Greater Research Opportunities (GRO) fellowships. Some of these students have moved on to careers in government while others are now full-time professors and researchers. Still others are working for state environmental agencies or furthering their studies through postdoctoral positions at universities. Since the inception of the NCER program, STAR fellowships (along with grants and SBIR projects) have been awarded in every state in the country. With the help of STAR, current and future scientists and engineers have been able to explore ways to preserve and protect human health and our precious resources.

    A novel Gram-stain-positive, non-motile, moderately halophilic and alkalitolerant actinobacterium, designated EGI 80432T, was isolated from a saline-alkaline soil of Xinjiang province, north-west China. Cells were non-endospore-forming cocci with a diameter of 0.5-0.8 μm. Strain EGI 80432T grew in the presence of 0-9 % (w/v) NaCl (optimum at 3-5 %), and also grew within the pH range 6.0-10.0 (optimum at pH 8.0-9.0) on marine 2216E medium. The peptidoglycan type was A1γ. The whole-cell hydrolysates contained glucose, galactose, mannose and three unknown sugars as major sugars. The predominant menaquinone was MK-9(H4). The major fatty acids were C17 : 1ω8c, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), C18 : 1ω9c and iso-C15 : 0 The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, one unknown phosphoglycolipid, three unknown phospholipids and four unknown polar lipids. The genomic DNA G+C content was 75.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain EGI 80432T clustered within the radius of the class Nitriliruptoria. Levels of sequence similarity between strain EGI 80432T and its phylogenetic neighbours Nitriliruptor alkaliphilus ANL-iso2T and Euzebya tangerina F10T were 94.1 and 88.1 %, respectively. Based on morphological, physiological and chemotaxonomic characteristics and phylogenetic analysis, a novel species of a new genus, Egicoccus halophilus gen. nov., sp. nov., is proposed, within the new family and new order Egicoccaceae fam. nov. and Egicoccales ord. nov. in the class Nitriliruptoria. The type strain of Egicoccus halophilus is EGI 80432T ( = CGMCC 1.14988T = KCTC 33612T). PMID:26552810

    The conversion of O-methylsterigmatocystin (OMST) and dihydro-O-methylsterigmatocystin to aflatoxins B1, G1, B2, and G2 requires a cytochrome P-450 type of oxidoreductase activity. ordA, a gene adjacent to the omtA gene, was identified in the aflatoxin-biosynthetic pathway gene cluster by chromosomal walking in Aspergillus parasiticus. The ordA gene was a homolog of the Aspergillus flavus ord1 gene, which is involved in the conversion of OMST to aflatoxin B1. Complementation of A. parasiticus SRRC 2043, an OMST-accumulating strain, with the ordA gene restored the ability to produce aflatoxins B1, G1, B2, and G2. The ordA gene placed under the control of the GAL1 promoter converted exogenously supplied OMST to aflatoxin B1 in Saccharomyces cerevisiae. In contrast, the ordA gene homolog in A. parasiticus SRRC 2043, ordA1, was not able to carry out the same conversion in the yeast system. Sequence analysis revealed that the ordA1 gene had three point mutations which resulted in three amino acid changes (His-400-->Leu-400, Ala-143-->Ser-143, and Ile-528-->Tyr-528). Site-directed mutagenesis studies showed that the change of His-400 to Leu-400 resulted in a loss of the monooxygenase activity and that Ala-143 played a significant role in the catalytic conversion. In contrast, Ile-528 was not associated with the enzymatic activity. The involvement of the ordA gene in the synthesis of aflatoxins G1, and G2 in A. parasiticus suggests that enzymes required for the formation of aflatoxins G1 and G2 are not present in A. flavus. The results showed that in addition to the conserved heme-binding and redox reaction domains encoded by ordA, other seemingly domain-unrelated amino acid residues are critical for cytochrome P-450 catalytic activity. The ordA gene has been assigned to a new cytochrome P-450 gene family named CYP64 by The Cytochrome P450 Nomenclature Committee. PMID:9835571

  17. EPA proposes new rules for injection wells

    NASA Astrophysics Data System (ADS)

    The U.S. Environmental Protection Agency (EPA) has proposed rule changes to strengthen regulations protecting underground sources of drinking water from underground injection of hazardous wastes. The action is authorized by the Resource Conservation and Recovery Act (RCRA) and the Safe Drinking Water Act. The proposed rules were published in Federal Register August 27, 1987.“This proposal assures that hazardous wastes will either be properly treated or placed in an area where they can't contaminate underground sources of drinking water,” said Lawrence J. Jensen, EPA Assistant Administrator for Water. “The regulations would prohibit the migration of untreated hazardous waste out of the injection zone.”

    The paper discusses a workshop held as a step toward EPA's prioritizing potential areas of research for applying pollution prevention to indoor air quality (IAQ). The workshop involved technical experts in the fields of IAQ, pollution prevention, and selected industries. Workshop goals were to identify major IAQ issues and their pollution prevention opportunities, and to suggest research strategies for IAQ/pollution prevention. The paper summarizes the suggestions made by workshop participants and highlights opportunities for IAQ/pollution prevention research.

    1993-03-01

    Superfund conjures up images of hazardous waste sites, which EPA is spending billions of dollars to remediate. One of the law's most worrisome effects is that it drains enormous economic resources without returning commensurate benefits. In a Sept. 1, 1991, front page article in The New York Times, experts argued that most health dangers at Superfund sites could be eliminated for a fraction of the billions that will be spent cleaning up the 1,200 high-priority sites across the country. Even EPA has suggested that the Superfund program may receive disproportionate resources, compared with other public health programs, such as radon in houses, the diminishing ozone layer and occupational diseases. Public opinion polls over the last decade consistently have mirrored the public's vast fear of hazardous waste sites, a fear as great as that held for nuclear power plants. Fear notwithstanding, the high cost of chosen remedies at given sites may have less to do with public health goals than with the method EPA uses to translate them into acceptable contaminant concentrations in soil, groundwater and other environmental media.

    The United States Environmental Protection Agency's (US EPA) digital science "enterprise" plays a critical role in US EPA's efforts to achieve its mission to protect human health and the environment. This enterprise is an evolving cross-disciplinary research and development construct, with social and institutional dimensions. It has an active development community and produces a portfolio of digital science products including decision support tools, data repositories, Web interfaces, and more. Earth sciences and sustainable development organizations from around the world - including US government agencies - have achieved various levels of success in taking advantage of the rapidly-evolving digital age. Efficiency, transparency and ability to innovate are tied to an organization's digital maturity and related social characteristics. Concepts like participatory web, data and software interoperability, global technology transfer, ontological harmonization, big data, scaling, re-use and open science are no longer "new and emerging." They have emerged and - in some cases - are tied to US government directives. We assess maturity, describe future scenarios, discuss new initiatives and outline steps for better leveraging the information age to more effectively and efficiently achieve US EPA's mission. The views expressed herein are those of the authors and do not necessarily reflect the views or policies of the organizations for which they work and/or represent.

  1. After two decades, EPA`s hazardous waste regulations still rule

    SciTech Connect

    Wray, T.K.

    1996-11-01

    The Environmental Protection Agency (EPA) promulgated the first hazardous waste management regulations nearly 20 years ago under the Resource Conservation and Recovery Act. The rules were designed to ensure that hazardous wastes would be managed in an environmentally safe manner from cradle to grave--from the point of generation to final disposal. The regulations have undergone several revisions but still consist of four basic parts--waste identification, generator rules, transporter rules, and treatment, storage and disposal rules. This article focuses on rules for generators. EPA regulations define three classes of generators, based on waste volume and toxicity. All generators must obtain an EPA identification number, which requires completion and filing of form 8700-12 ``Notification of Hazardous Waste Activity.`` The alphanumeric identification numbers typically are issued by state environmental regulatory agencies.

  2. EPA's ''Lead leaching from submersible well pumps''

    1994-06-01

    An attempt is made to provide comprehensive answers to questions EPA anticipates those involved in the environmental health profession may encounter from public concern in response to national media coverage of drinking water submersible well pumps and lead leaching. In laboratory tests, several models of new, previously unused submersible pumps with brass and bronze components have been found to leach high levels of lead into the water that comes in contact with these pumps. The findings of these tests indicate cause for concern to users of such pumps and a need for further research. Questions concerning the extent of the problem, health effects, and solutions are addressed.

  3. EPA's GLP compliance review of chemistry laboratories.

    PubMed

    Hill, D F

    1993-01-01

    The Good Laboratory Practice (GLP) Standards regulations do not provide specific requirements for the operation of a specimen analysis laboratory, such as a testing facility that performs pesticide residue analysis in support of a tolerance study. Thus, some judgment must be applied by a regulated analytical laboratory to assure compliance with GLP Standards regulations that were designed primarily for testing facilities that apply test substances to test systems. This presentation will provide some insight as to EPA's compliance approach, as well as identifying problem areas encountered in past inspections of analytical laboratories. PMID:8156226

    2015-11-01

    A morphometric analysis of river network, basins and relief using geomorphic indices and geostatistical analyses of Digital Elevation Model (DEM) are useful tools for discussing the morphometric evolution of the basin area. In this study, three different indices including valley floor width to height ratio (Vf), stream gradient (SL), and stream sinuosity were applied to Afşin-Elbistan lignite basin to test the imprints of tectonic activity. Perturbations of these indices are usually indicative of differences in the resistance of outcropping lithological units to erosion and active faulting. To map the clusters of high and low indices values, the Kernel density estimation (K) and the Getis-Ord Gi∗ statistics were applied to the DEM-derived indices. The K method and Gi∗ statistic highlighting hot spots and cold spots of the SL index, the stream sinuosity and the Vf index values helped to identify the relative tectonic activity of the basin area. The results indicated that the estimation by the K and Gi∗ including three conceptualization of spatial relationships (CSR) for hot spots (percent volume contours 50 and 95 categorized as high and low respectively) yielded almost similar results in regions of high tectonic activity and low tectonic activity. According to the K and Getis-Ord Gi∗ statistics, the northern, northwestern and southern parts of the basin indicates a high tectonic activity. On the other hand, low elevation plain in the central part of the basin area shows a relatively low tectonic activity.

  5. Mixed welcome: Beware of some limitations in EPA`s audit policy

    SciTech Connect

    Hill, M.

    1996-03-01

    The US Environmental Protection Agency`s Final Policy on Environmental Audits became effective January 22. The policy provides guidance on penalty mitigation for voluntary disclosures of environmental violations, and replaces EPA`s March 30, 1995, Interim Policy. In the Final Policy, EPA gives three basic incentives for companies to conduct audits: full or partial waiver of penalties for violations discovered; no recommendations for criminal prosecution; and no routine requests for environmental audits. To achieve these benefits, however, the policy demands adherence to nine separate conditions. Moreover, EPA remains opposed to providing immunity or recognizing privilege--even when created by state statutes--with respect to environmental audits. The policy also provides no protections to individual managers or employees. Finally, the agency has retained broad discretion to deviate from the policy on a case-by-case basis; thus, the policy provides little certainty to industry. Although the policy is a welcome step in the right direction, companies should be aware of the many limitations in the policy as they consider implementing environmental audit or due-diligence systems.

  6. Repackaging, refilling, cross contamination - EPA perspective

    SciTech Connect

    Wingett, M.J.

    1994-12-31

    Section 3 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires all pesticide products to be registered by the Environmental Protection Agency (EPA) to ensure that their use will not pose an unreasonable risk to human health or the environment. Changes in formulation of a registered pesticide product and repackaging of a pesticide product into another container are examples of two activities which are considered {open_quotes}production{close_quotes} of a new pesticide product and which require separate registration as a new pesticide under FIFRA. Based upon the results of inspections and the experience of other EPA Regions and the states, it is apparent that there is a need for technical and compliance assistance concerning bulk pesticide repackaging. There is also a need to develop more data on the extent and risk of pesticide cross-contamination of bulk repackaged pesticides. There is also a need for members of the regulated community to evaluate their own operations and practices concerning bulk pesticide repackaging to ensure compliance with Agency regulations and policies.

  7. Court date for EPA acid rain rule

    SciTech Connect

    Lobsenz, G.

    1994-03-04

    In an acid rain rulemaking that appears headed straight for the courtroom, the Environmental Protection Agency this week announced new limits on emissions of nitrogen oxides from coal-fired power plants. The regulations, announced March 1, are expected to achieve a 1.8 million ton per year reduction in power plant NOx emissions, which are considered a major contributor to acid rain. The agency issued companion regulations last year to cut power plant discharges of sulfur dioxide, the other major acid rain pollutant. The NOx rulemaking elicited contradictory responses from utility industry officials. One point of contention involves the agency's definition of low-NOx burner technology, a key regulatory determination. If a utility installs EPA-defined low-NOx burner technology and still cannot meet the new NOx limits, it can apply for a less stringent [open quotes]alternative emission limit.[close quotes] The other issue likely to be raised by industry officials involves the January 1995 compliance deadline for utilities included in Phase I of the NOx program. While EPA will allow individual utilities to seek a deadline extension until April 1996 in the event of operational difficulties, the agency rejected the industry's request for an across-the-board extension.

    The stress of migration as well as social factors and changes related to the receiving society may lead to the manifestation of psychiatric disorders in vulnerable individuals after migration. The diversity of cultures, ethnicities, races and reasons for migration poses a challenge for those seeking to understand how illness is experienced by immigrants whose backgrounds differ significantly from their clinicians. Cultural competence represents good clinical practice and can be defined as such that a clinician regards each patient in the context of the patient's own culture as well as from the perspective of the clinician's cultural values and prejudices. The EPA Guidance on cultural competence training outlines some of the key issues related to cultural competence and how to deal with these. It points out that cultural competence represents a comprehensive response to the mental health care needs of immigrant patients and requires knowledge, skills and attitudes which can improve the effectiveness of psychiatric treatment. To reach these aims, both individual and organizational competence are needed, as well as teaching competence in terms of educational leadership. The WPA Guidance on Mental Health and Mental Health Care for Migrants and the EPA Guidance on Mental Health Care for Migrants list a series of recommendations for policy makers, service providers and clinicians; these are aimed at improving mental health care for immigrants. The authors of this paper would like to underline these recommendations and, focusing on cultural competency and training, believe that they will be of positive value. PMID:25725596

  9. State acid rain permitting programs: A report from EPA

    1995-12-31

    States and EPA are laying the groundwork for state acid rain permitting in Phase 2 of the Acid Rain Program. Early indications suggest a high degree of state compliance with the acid rain permitting requirements of the Acid Rain Program. Phase 2 acid rain permitting forms have been revised and are available on EPA`s Technology Transfer Network. EPA has developed a policy and rationale concerning submission of Phase 2 permit applications, as well as suggested state timing and methodology regarding adoption of 40 CFR Part 76, the NO{sub x} regulation.

  10. Computational toxicology as implemented by the U.S. EPA: providing high throughput decision support tools for screening and assessing chemical exposure, hazard and risk.

    PubMed

    Kavlock, Robert; Dix, David

    2010-02-01

    Computational toxicology is the application of mathematical and computer models to help assess chemical hazards and risks to human health and the environment. Supported by advances in informatics, high-throughput screening (HTS) technologies, and systems biology, the U.S. Environmental Protection Agency EPA is developing robust and flexible computational tools that can be applied to the thousands of chemicals in commerce, and contaminant mixtures found in air, water, and hazardous-waste sites. The Office of Research and Development (ORD) Computational Toxicology Research Program (CTRP) is composed of three main elements. The largest component is the National Center for Computational Toxicology (NCCT), which was established in 2005 to coordinate research on chemical screening and prioritization, informatics, and systems modeling. The second element consists of related activities in the National Health and Environmental Effects Research Laboratory (NHEERL) and the National Exposure Research Laboratory (NERL). The third and final component consists of academic centers working on various aspects of computational toxicology and funded by the U.S. EPA Science to Achieve Results (STAR) program. Together these elements form the key components in the implementation of both the initial strategy, A Framework for a Computational Toxicology Research Program (U.S. EPA, 2003), and the newly released The U.S. Environmental Protection Agency's Strategic Plan for Evaluating the Toxicity of Chemicals (U.S. EPA, 2009a). Key intramural projects of the CTRP include digitizing legacy toxicity testing information toxicity reference database (ToxRefDB), predicting toxicity (ToxCast) and exposure (ExpoCast), and creating virtual liver (v-Liver) and virtual embryo (v-Embryo) systems models. U.S. EPA-funded STAR centers are also providing bioinformatics, computational toxicology data and models, and developmental toxicity data and models. The models and underlying data are being made publicly

    Miller, C.A.; Lemieux, P.M.

    1998-12-31

    The abstract provides a brief description of the work at EPA`s to apply artificial intelligence (AI) methods to control certain combustion emissions. In recent years, studies have been conducted to evaluate fuzzy logic and artificial neural networks as means to improve the performance of combustion systems and instrumentation to monitor those systems. A mission of EPA`s is the application of new technologies to the problem of preventing and controlling air pollution from combustion sources. One area of interest is the use of AI methods to improve the performance of existing air pollution control technologies, in terms of both operating and economic efficiencies.

    At the request of the Subcommittee on Natural Resources, Agriculture Research and Environment and the Subcommittee on Civil Service, House of Representatives, GAO reviewed the operations of the Office of Inspector General, Environmental Protection Agency, under the leadership of former Inspector General Matthew Novick. GAO found that although most investigations appear to have been handled properly, in some cases all relevant matters were not followed up and consistently addressed. GAO also noted the need to use investigative resources more effectively and to provide more balanced audit coverage. Acting Inspector General Charles Dempsey recognized and made a concerted effort to correct many problems during his tenure. GAO recommends further actions to strengthen inspector general operations at EPA.

  13. Comparison of EPA's QMS to SEI's CMMI.

    2001-01-01

    EPA and other government organizations make decisions based on environmental measurements. How good are the data? How well are the data generators performing? What measurements apply to them? How can the data life cycle processes be improved so data generators can continually provide the best data? EPA's Quality Management System requirements go beyond evaluation of environmental data quality itself to examine systems associated with production, collection, processing (validation/verification), transfer, reduction, storage, and retrieval of data throughout a life cycle. This QMS specifies minimum quality requirements for particular environmental programs. But how can you measure and compare programs that go well beyond the minimum, towards optimal quality? This paper compares EPA's requirements for Quality Management Systems (R2) and Project Plans (R5) to the Software Engineering Institute Capability Maturity Model (CMMISM). The CMMISM model provides for growth (staged or continuous) and a comprehensive assessment that is not yet provided in EPA's R2 or R5. Properly implemented, the CMMISM model serves as a quality framework for integrating and aligning organizational processes and implementing a program of continual process improvements. It identifies process areas ("things to do"), and provides measures of performance ("how well things are done") against specific goals and practices. CMMISM uses a Systems Engineering Management approach, built on process models, that helps identify "how good" the system is. Goodness is defined as stages in a complete model for optimal operation. CMMISM provides two methods for evaluating the goodness of the project. The Staged model in CMMISM provides a Maturity Level that is a well-defined evolutionary plateau describing the manner in which a specified set of processes are performed. As the organization advances in maturity, these levels become more defined and processes are tailored for specific project needs. The other method

  14. EPA in disarray: muzzling the watchdog

    SciTech Connect

    Goldberg, P.

    1981-12-01

    The average American's exposure to toxic industrial chemicals could double in the next 10 years as the chemical industry expands and chemicals continue to collect and concentrate in the environment because the administration plans to throw away needed environmental regulations along with the unneeded and ill-advised ones. The plan favors short-term economic gains for industry over long-term health and safety considerations. Budget cutbacks are eliminating funds for inspectors and increasing the risks of illegal dumping which accounts for an estimated 80% of chemical wastes. The author feels that Environmental Protection Agency (EPA) Director Ann Gorsuch, who brings no knowledge of chemistry or administration to the job, will halt funding for dump cleanups and delay the implementation of pollution regulations despite polls which show the public wants them to proceed.

  11. Review of the cost-effectiveness of EPA`s offshore oil and gas effluent guidelines

    SciTech Connect

    Veil, J.A.

    1991-12-31

    The United States Environmental Protection Agency (EPA) published proposed Effluent Limitation Guidelines and New Source Performance Standards for the Offshore Subcategory of the Oil and Gas Extraction Point Source Category on March 13, 1991 (56 FR 10664). These guidelines include limitations for Best Practicable Technology (BPT), Best Conventional Technology (BPT), Best Available Technology (BAT), and New Source Performance Standards (NSPS) for produced water, drilling fluids, drill cuttings, well treatment fluids, deck drainage, produced sand, and sanitary and domestic waste. As a support document to these regulations, EPA published a Cost-Effectiveness (CE) Analysis (EPA, 1991). This report calculated the CE of several different BAT and NSPS treatment options for produced water and drilling fluids and drill cuttings. Separate calculations were made for restricted versus unrestricted drilling rights and for three different oil costs per barrel. Each treatment option has a different cost and will result in removal of different levels of pollutants. The report calculates the annualized cost for each option and the pound equivalents (PE) removed and expresses the CE as $/PE. While not officially required for decision-making, as long as the CE falls within some reasonable range, the selected treatment option is considered acceptable. This paper examines the premises and assumptions used in the CE analysis and recalculates the CE statistic using alternate assumptions.

  12. EPA`s White Paper won`t ease everyone`s Title V headaches

    SciTech Connect

    Merrill, J.W.

    1996-01-01

    The Environmental Protection Agency issued a White Paper for Streamlined Development of a Part 70 Permit Application. The paper was developed in response to industry`s and permitting authorities` concerns that the current permitting process is costly and burdensome. The paper comes on the heels of a recent congressional debate over EPA cutbacks and intervention in the air program. This policy statement appears to be an attempt to keep Congress at bay while appeasing industry in the wake of numerous lawsuits which were filed after the original Part 70 regulations were issued. The White Paper acknowledges the lack of clarity in the original Part 70 permit program, and attempts to limit the scope and responsibility that sources have in preparing a complete Title 5 application. Unfortunately for many sources, states already have initiated their Title 5 programs and, in many cases, already have requested application submittals. It is unlikely that these states will be able to revise state laws, regulations and applications in time for sources to take advantage of the change in EPA`s position.

  14. Analysis of EPA`s cost-effectiveness study for the coastal oil and gas effluent limitations guidelines

    SciTech Connect

    Veil, J.

    1995-05-01

    The US Environmental Protection Agency (EPA) conducted a cost-effectiveness (CE) analysis to estimate the incremental cost of complying with the proposed effluent limitation guidelines (ELGs) for the coastal oil and gas industry (EPA 1995a). EPA`s CE analysis calculates the pounds of each pollutant that would be removed if the chosen discharge option is selected. In 1993, EPA issued final ELGs for the offshore oil and gas industry and published an offshore CE analysis. The chemical characteristics of produced water from the offshore region are essentially the same as those of produced water from the coastal region. It was surprising, therefore, that EPA chose a much longer list of pollutants and generally stricter weighting factors for the coastal CE analysis. This report reviews the data, assumptions, and analyses used in EPA`s coastal CE analysis and identifies alternate data, assumptions, and analyses that could lead to significantly different cost-effectiveness conclusions. Two alternate lists of pollutants are proposed, along with recalculated weighting factors for several pollutants that contributed a large proportion of the total PEs removed--radium, benzo(a)pyrene, boron, and ammonia. By using different combinations of these variables, a range of revised estimates of CE is calculated.

  20. Developments in EPA`s air dispersion modeling for hazardous/toxic releases

    SciTech Connect

    Touma, J.S.

    1995-12-31

    Title 3 of the 1990 Clean Air Act Amendments (CAAA) lists many chemicals as hazardous air pollutants and requires establishing regulations to prevent their accidental release, and to minimize the consequence, if any such releases occur. With the large number of potential release scenarios that are associated with these chemicals, there is a need for a systematic approach for applying air dispersion models to estimate impact. Because some chemicals may form dense gas clouds upon release, and dispersion models that can simulate these releases are complex, EPA has paid attention to the development of modeling tools and guidance on the use of models that can address these types of releases.

    2010-01-01

    Objective We examined the efficacy and tolerability of ethyl-eicosapentaenoate (EPA-E) monotherapy for major depressive disorder (MDD) in a double-blind, randomized controlled pilot study. Methods 57 adults with DSM-IV MDD were randomized from 1/2003-6/2006 to receive 1 gram/day of EPA or placebo (PBO) for 8 weeks. Response criteria were based on the Hamilton-D-17 scale. Subjects' plasma lipid profiles were examined by gas chromatography. Results 35 subjects (63% female; mean age 45+/-13 yrs) were eligible for the intent to treat (ITT) analysis. In the ITT sample, mean HAM-D-17 scores decreased from 21.6+/-2.7 to 13.9+/-8.9 for the EPA group (n=16) and from 20.5+/-3.6 to 17.5+/-7.5 for the PBO group (n=19) (p=0.123); the effect size for EPA was 0.55. ITT response rates were 38% (6/16) for EPA, and 21% (4/19) for PBO (p=0.45). Among the 24 study completers, mean HAM-D-17 scores decreased from 21.3+/-3.0 to 11.1+/-8.1 for the EPA group and from 20.5+/-3.8 to 16.3+/-6.9 for the PBO group (p=0.087); the effect size for EPA was 0.73. Completer response rates were 45% (5/11) for EPA, and 23% (3/13) for PBO (p=0.39). Among EPA subjects, baseline n-6/n-3 ratio was associated with decrease in HAM-D-17 score (r= -0.686, p=0.030) and with treatment response (p=0.032); change in n-6/n-3 ratio was associated with change in HAM-D-17 score (r=0.784, p=0.032). Side effects, reported in 2 EPA subjects and 5 PBO subjects, were exclusively gastrointestinal, mild, and not associated with discontinuation. Conclusions EPA demonstrated an advantage over placebo that did not reach statistical significance, possibly due to the small sample and low completer rates, which were the major study limitations.

    Henriques, W.D.; Dixon, K.R.

    1994-12-31

    Using data from the Environmental Protection Agency`s Toxic Release Inventory 1988 (EPA TRI88), pollutant concentration estimates were modeled for a point source air release of 1,1,1-trichloroethane at the Savannah River Plant located in Aiken, South Carolina. Estimates were calculating using the EPA`s SCREEN model utilizing typical meteorological conditions to determine maximum impact of the plume under different mixing conditions for locations within 100 meters of the stack. Input data for the SCREEN model were then manipulated to simulate the impact of the release under urban conditions (for the purpose of assessing future landuse considerations) and under flare release options to determine if these parameters lessen or increase the probability of human or wildlife exposure to significant concentrations. The results were then compared to EPA reference concentrations (RfC) in order to assess the size of the buffer around the stack which may potentially have levels that exceed this level of safety.

  4. Magnetococcus marinus gen. nov., sp. nov., a marine, magnetotactic bacterium that represents a novel lineage (Magnetococcaceae fam. nov., Magnetococcales ord. nov.) at the base of the Alphaproteobacteria.

    2013-03-01

    Magnetotactic bacteria are a morphologically, metabolically and phylogenetically disparate array of bacteria united by the ability to biomineralize membrane-encased, single-magnetic-domain mineral crystals (magnetosomes) that cause the cell to orientate along the Earth's geomagnetic field. The most commonly observed type of magnetotactic bacteria is the ubiquitous magnetotactic cocci, which comprise their own phylogenetic group. Strain MC-1(T), a member of this group, was isolated from water collected from the oxic-anoxic interface of the Pettaquamscutt Estuary in Rhode Island, USA, and cultivated in axenic culture. Cells of strain MC-1(T) are roughly spherical, with two sheathed bundles of flagella at a single pole (bilophotrichous). Strain MC-1(T) uses polar magnetotaxis, and has a single chain of magnetite crystals per cell. Cells grow chemolithoautotrophically with thiosulfate or sulfide as the electron donors, and chemo-organoheterotrophically on acetate. During autotrophic growth, strain MC-1(T) relies on the reductive tricarboxylic acid cycle for CO2 fixation. The DNA G+C content is 54.2 mol%. The new genus and species Magnetococcus marinus gen. nov., sp. nov. are proposed to accommodate strain MC-1(T) ( = ATCC BAA-1437(T)  = JCM 17883(T)), which is nominated as the type strain of Magnetococcus marinus. A new order (Magnetococcales ord. nov.) and family (Magnetococcaceae fam. nov.) are proposed for the reception of Magnetococcus and related magnetotactic cocci, which are provisionally included in the Alphaproteobacteria as the most basal known lineage of this class.

    1995-03-01

    EPA`s control systems research is concentrated in three areas: electric motors, wind turbines, and combustion technologies. In general, these projects are concerned with pollution prevention through enhanced efficiency of operation and pollution control through lower emission levels. Pioneering effort has been achieved in the application of fuzzy-logic-based controls in these areas. Based on the results of these projects, fuzzy logic has emerged as an important tool in environmental technology for pollution elimination and control.

  6. The Clean Air Act`s enforcement ace: An overview of EPA`s credible evidence rule

    SciTech Connect

    Paul, P.J.

    1997-12-31

    The 1990 Clean Air Act ({open_quotes}CAA{close_quotes}) amendments included numerous provisions directing EPA to require owners or operators to conduct enhanced monitoring and to make compliance certifications. These provisions contained in both those Title V (Operating Permits) and Title VII (Enforcement) of those amendments. Section 503(b)(2) of the amended CAA requires at least annual certifications of compliance with permit requirements and prompt reporting of any deviations from such requirements. Section 114(a)(3) of the CAA requires EPA to promulgate rules on enhanced monitoring and compliance certifications. On October 23, 1993, EPA proposed its {open_quotes}enhanced monitoring{close_quotes} rule. The enhanced monitoring proposal also included the Conceptual approach of using {open_quotes}presumptively credible evidence{close_quotes} in enforcement actions. Further, this proposal also would have allowed the use of {open_quotes}credible evidence,{close_quotes} other than reference or compliance test data to establish noncompliance in an enforcement action. In approximately three weeks, EPA is scheduled to republish as a final rule, the credible evidence provisions of the original enhanced monitoring rule with apparently minor revisions. This paper briefly summarizes the history, status, and likely impact EPA`s {open_quotes}any credible evidence{close_quotes} ({open_quotes}ACE{close_quotes}) rule.

  7. U.S. EPA`s use of QSAR for new and existing chemical evaluations: Regulatory aspects

    SciTech Connect

    Zeeman, M.; Clements, R.G.; Nabholz, J.V.; Auer, C.M.

    1994-12-31

    As up front testing is not required, ecotoxicity or fate data are available for only about 5% of the 2,200 new chemicals/year submitted to EPA. The EPA`s Toxic Substances Control Act (TSCA) Inventory of existing chemicals currently lists about 72,000 chemicals. Most of existing chemicals also appear to have little or no ecotoxicity or fate data available. The EPA`s Office of Pollution Prevention and Toxics (OPPT) has developed and relies upon QSARs to estimate the ecotoxicity and fate of most of the new chemicals evaluated for ecological hazard and risk assessment. QSAR methods routinely result in ecotoxicity estimations of acute and sub/chronic toxicity to fish, aquatic invertebrates, and algae, and fate estimations of physical/chemical properties, degradation, and bioconcentration. GSAR methods were also used to screen the TSCA Inventory for the ecotoxicity of specific chemical classes of over 8,000 discrete chemicals. In the latter effort, seven major chemical classes made up almost 95% of these chemicals. From this QSAR analysis, about 10--20% or 15--18% of these chemicals, respectively, are expected to have high acute or high chronic toxicity to aquatic species. Estimates of ecotoxicity for > 8,000 discrete organics enhances prioritization of chemicals on the TSCA Inventory and helps focus EPA/OPPT regulatory efforts upon the potentially most toxic substances.

  8. EPA`s proposed metal sediment criteria: Good news for industry

    SciTech Connect

    Bleiler, J.A.

    1996-09-01

    A recent Environmental Protection Agency initiative may enable contaminated-site owners and other responsible parties to negotiate more realistic sediment cleanup actions with state and federal agencies. EPA in December 1994 issued Equilibrium Partitioning Approach to Predicting Metal Bioavailability in Sediments and the Derivation of Sediment Quality Criteria (SQC) for Metals, a report on metals contamination in sediments. This document marks the agency`s first national initiative to develop SQC for metals. Because it could reduce site remediation costs substantially, the new approach may be good news for industry. The initiative`s goal is to protect sediment-dwelling organisms from toxic levels of such metals as cadmium, lead, zinc, nickel and copper.

  18. EPA`s model open market trading rule - can it work?

    SciTech Connect

    Wrenn, C.M.

    1996-11-01

    The 1990 Amendments to the CAA established new deadlines for meeting the health standard for ozone and significant EPA, state industry effort has been made to reach the defined attainment goals. While great progress has been made towards acheiving a healthier air quality under the CAA, over 100 million people still live in areas that do not meet the ozone health standard. All of these areas have requirements for resonably available control technology (RACT) for major stationary sources of VOC and NO{sub x}. However, industry and mobile sources are still producing concentrations of ozone precursors (NO{sub x} & VOC) that cause or smog, a phenomenon which is especially severe during warm weather seasons. High ground-level ozone concentrations have been linked to health problems in adults and children and damage of synthetic materials, property, crops, forest and natural systems. Traditional {open_quotes}smog{close_quotes} reduction programs in the U.S. (e.g, RACT) have always focused on curtailing emissions from each and every stack. As a result, sources which are more difficult to control pay a disproportionaltely high cost to comply. Without the ability to pass on cost efficiencies between participants, the overall cost of compliance remains high, affecting productivity and possibly future expansion plans. The EPA has recognized the inefficiency involved in this strategy and, since the late 1970`s has developed policies which permit a variety of {open_quotes}emissions trading{close_quotes} approaches. The Open Market Trading Rule (OMTR) is one of these approaches.

    On June 6, 1996, EPA`s Acid Rain Program published an advance notice of proposed rulemaking (ANPRM) in the Federal Register seeking comment on: (1) whether to change the design of the annual sulfur dioxide (SO{sub 2}) allowance auctions; (2) whether to change the timing of the allowance auctions; (3) whether to change the requirement that the minimum price of offered allowances must be in whole dollars, and (4) whether EPA should propose the ability to submit allowance transfers electronically. EPA also published on that day a proposed and direct final rule on whether to eliminate the direct sale. This paper documents the issues addressed in the ANPRM, the comments EPA received, and EPA`s responses to those comments. EPA received comments from 14 separate commenters.

    Several closely-related, thermophilic, and cellulolytic bacterial strains, designated JKG1T, JKG2, JKG3, JKG4, and JKG5, were isolated from a cellulolytic enrichment (corn stover) incubated in the water column of Great Boiling Spring, NV. Strain JKG1T had cells of a diameter of 0.7 - 0.9 μm and length of ~2.0 μm that formed non-branched multicellular filaments reaching >300 μm. Spores were not formed and dense liquid cultures were red. The temperature range for growth was 45-65 °C, with an optimum of 55 °C. The pH range for growth was 5.6-9.0, with an optimum of 7.5. JKG1T grew as an aerobic heterotroph, utilizing glucose, sucrose, xylose, arabinose, cellobiose, carboxymethylcellulose, filter paper, microcrystalline cellulose, xylan, starch, casamino acids, tryptone, peptone, yeast extract, acetate, citrate, lactate, pyruvate, and glycerol as sole carbon sources, and was not observed to photosynthesize. The cells stained Gram-negative. Phylogenetic analysis using 16S rRNA gene sequences placed the new isolates in the class Chloroflexia, but distant from other cultivated members, with the highest sequence identity of 82.5% to Roseiflexus castenholzii. The major quinone was menaquinone-9; no ubiquinones were detected. The major cellular fatty acids (>5%) were C18:0, anteiso-C17:0, iso-C18:0, and iso-C17:0. C16:0, iso-C16:0, and C17:0. The peptidoglycan amino acids were alanine, ornithine, glutamic acid, serine, and asparagine. Whole-cell sugars included mannose, rhamnose, glucose, galactose, ribose, arabinose, and xylose. Morphological, phylogenetic, and chemotaxonomic results suggest that JKG1T is representative of a new lineage within the class Chloroflexia, which we propose to designate Kallotenue papyrolyticum gen. nov., sp. nov., Kallotenuaceae fam. nov., Kallotenuales ord. nov.

    A novel autotrophic bacterium, strain skN76T, was isolated from sediment of a lake in Japan. As sole electron donor to support chemolithoautotrophic growth, the strain oxidized thiosulfate, tetrathionate and elemental sulfur. For growth, the optimum temperature was 42–45 °C and the optimum pH was 6.8–8.2. The cells were Gram-stain-negative, catalase-positive and oxidase-positive. The strain exhibited changes in morphology depending on growth temperature. Cells grown at the optimum temperature were rod-shaped (0.9–3.0 μm long and 0.3–0.5 μm wide), whereas a filamentous form was observed when the strain was cultured at the lowest permissive growth temperatures. The G+C content of genomic DNA was 69 mol%. The major components in the fatty acid profile were C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the closest cultivated relative of strain skN76T was Acidiferrobacter thiooxydans m-1T, with sequence similarity of 93 %. On the basis of its phylogenetic and phenotypic properties, strain skN76T ( = DSM 100313T =  NBRC 110942T) is proposed as the type strain of a novel species of a novel genus, Sulfurifustis variabilis gen. nov., sp. nov. Novel taxa, Acidiferrobacteraceae fam. nov. and Acidiferrobacterales ord. nov., are also proposed to accommodate the genera Acidiferrobacter and Sulfurifustis gen. nov. PMID:26220671

    A novel obligately halophilic, facultatively alkaliphilic actinobacterium, designated EGI 80759T, was isolated from the rhizosphere of Tamarix hispida Willd, Karamay, Xinjiang province, north-west China. Cells of strain EGI 80759T were Gram-stain-positive, non-motile and non-endospore-forming rods. Strain EGI 80759T showed obligately halophilic growth with a tolerance to 8-25 % (w/v) NaCl (optimum growth at 10-12 %, w/v) and facultatively alkaliphilic growth within the pH range 7.0-11.0 (optimum growth at pH 9.0-10.0). Cell-wall hydrolysates of the isolate contained meso-diaminopimelic acid (peptidoglycan type A1γ), with glucose, glucosamine, ribose and mannose as the major sugars. The major fatty acids identified were 10-methyl-C17 : 0, C17 : 1ω8c and C17 : 0. The predominant menaquinone was MK-9(H4). The G+C content of the genomic DNA was 72.1 mol%. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain EGI 80759T clustered with members of the class Nitriliruptoria and showed highest 16S rRNA gene sequence similarities with Euzebya tangerina F10T (90.3 %) and Nitriliruptor alkaliphilus ANL-iso2T (88.1 %). On the basis of the data obtained from phenotypic and chemotaxonomic studies and the phylogenetic analysis, the isolate is proposed to be a representative of a novel genus and a novel species, Egibacter rhizosphaerae gen. nov., sp. nov., of a proposed novel family, Egibacteraceae fam. nov., and order, Egibacterales ord. nov., within the class Nitriliruptoria. The type strain of the type species, Egibacter rhizosphaerae, is EGI 80759T ( = CGMCC 1.14997T = KCTC 39588T). PMID:26510781

  4. Overview of the EPA quality system for environmental programs

    SciTech Connect

    Johnson, G.L.

    1993-12-31

    Formalized quality assurance program requirements for the U.S. Environmental Protection Agency (EPA) have been established for more than a decade. During this period, the environmental issues and concerns addressed by the EPA have changed. Many issues, such as ozone depletion and global climate warming, have become international concerns among the world environmental community. Other issues, such as hazardous waste cleanup and clean air, remain a focus of national environmental concerns. As the environmental issues of the 1980`s evolved, the traditional quality assurance (QA) program was transformed through the use of quality management principles into a Quality System to help managers meet the needs of the 1990`s and beyond.

    2012-01-17

    Environmental protection in the United States has reached a critical juncture. It has become clear that to address the complex and interrelated environmental challenges we face, we must augment our traditional approaches. The scientific community must build upon its deep understanding of risk assessment, risk management, and reductionism with tools, technologies, insights and approaches to pursue sustainability. The U.S. Environmental Protection Agency (EPA) has recognized this need for systemic change by implementing a new research paradigm called "The Path Forward." This paper outlines the principles of the Path Forward and the actions taken since 2010 to align EPA's research efforts with the goal of sustainability. PMID:22216884

  6. Are EPA's proposed revisions to the PM standards appropriate?

    2006-06-15

    In 1997 then-US Environmental Protection Agency (EPA) Administrator Carol Browner adopted new National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5). Browner recognized that 'there is uncertainty in the characterization of health effects attributable to exposure to ambient PM.' As a result, President Clinton promised to review the scientific basis for those standards prior to their implementation. Recently, before EPA has even promulgated rules concerning implementation of those standards, the agency proposed to revise those standards to make them significantly more stringent. Are the proposed revisions to the standards appropriate? The author argues. 41 refs.

    /protein sequences and the unique shared presence of large numbers of molecular signatures, members of clades A and B are indicated to be distinct from all other haloarchaea because of their uniquely shared evolutionary histories. Based upon these results, it is proposed that clades A and B be recognized as two new orders, Natrialbales ord. nov. and Haloferacales ord. nov., within the class Halobacteria, containing the novel families Natrialbaceae fam. nov. and Haloferacaceae fam. nov. Other members of the class Halobacteria that are not members of these two orders will remain part of the emended order Halobacteriales in an emended family Halobacteriaceae. PMID:25428416

  12. Evaluation of mercury speciation by EPA (Draft) Method 29

    SciTech Connect

    Laudal, D.L.; Heidt, M.K.; Nott, B.

    1995-11-01

    The 1990 Clean Air Act Amendments require that the U.S. Environmental protection Agency (EPA) assess the health risks associated with mercury emissions. Also, the law requires a separate assessment of health risks posed by the emission of 189 tract chemicals (including mercury) for electric utility steam-generating units. In order to conduct a meaningful assessment of health and environmental effects, we must have, among other things, a reliable and accurate method to measure mercury emissions. In addition, the rate of mercury deposition and the type of control strategies used may depend upon the type of mercury emitted (i.e., whether it is in the oxidized or elemental form). It has been speculated that EPA (Draft) Method 29 can speciate mercury by selective absorption; however, this claim has yet to be proven. The Electric Power Research Institute (EPRI) and the U.S. Department of Energy (DOE) have contracted with the Energy & Environmental Research Center (EERC) at University of North Dakota to evaluate EPA (Draft) Method 29 at the pilot-scale level. The objective of the work is to determine whether EPA (Draft) Method 29 can reliably quantify and speciate mercury in the flue gas from coal-fired boilers.
