    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.

  2. An examination of the Environmental Protection Agency risk assessment principles and practices: a brief commentary on section 4.1.3 of the EPA March 2004 Staff Paper.

    2006-01-01

    The US Environmental Protection Agency (EPA) recently issued a Staff Paper that articulates current risk assessment practices. In section 4.1.3, EPA states, "... effects that appear to be adaptive, non-adverse, or beneficial may not be mentioned." This statement may be perceived as precluding risk assessments based on non-default risk models, including the hormetic--or biphasic--dose-response model. This commentary examines several potential interpretations of this statement and the anticipated impact of ignoring hormesis, if present, in light of necessary conservatism for protecting human and environmental health, and the potential for employing alternative risk assessment approaches.

    1997-12-01

    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

  5. EPA`s program for risk assessment guidelines: Quantification issues

    SciTech Connect

    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.

  7. Statutory complexity disguises agency capture in Citizens Coal Council v. EPA

    SciTech Connect

    Mullen, R.

    2007-07-01

    In Citizens Coal Council v. EPA, an en banc panel for the Sixth Circuit Court of Appeals considered a challenge to EPA regulations promulgated pursuant to the Clean Water Act (CWA). The EPA promulgated the regulations in an attempt to incentivize coal companies to remine once abandoned mine sites. Petitioners, two nonprofit environmental organizations, claimed that the regulations violated the Clean Water Act and Administrative Procedure Act by allowing coal companies to remine without adhering to any enforceable pollution limitations. The EPA countered that more remining would improve water quality at abandoned sites. The Sixth Circuit rejected Petitioners' claims, finding that the EPA's regulations were reasonably consistent with the CWA's goal of restoring the integrity of the nation's waters. In so holding, the court struggled to understand the meaning of the CWA's complex procedural and technical language, and allowed the EPA to justify the rule based on the CWA's broad statement of purpose. Such superficial judicial review sets a dangerous precedent in environmental law, because it exacerbates the risk of agency capture. A captured agency promulgates regulations that benefit-industry, not the environment. Without the judiciary acting as a meaningful check against agency capture, the public loses a valuable tool in the fight against major-industrial polluters like the domestic coal industry. Citizens Coal Council therefore stands as a cautionary tale, a warning sign that the judiciary may be unable to identify agency capture where the regulations at issue are promulgated pursuant to a complex statute like the Clean Water Act.

    2011-07-15

    The U.S. Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) Program develops assessments of health effects that may result from chronic exposure to chemicals in the environment. The IRIS database contains more than 540 assessments. When supported by available data, IRIS assessments provide quantitative analyses of carcinogenic effects. Since publication of EPA's 2005 Guidelines for Carcinogen Risk Assessment, IRIS cancer assessments have implemented new approaches recommended in these guidelines and expanded the use of complex scientific methods to perform quantitative dose-response assessments. Two case studies of the application of the mode of action framework from the 2005 Cancer Guidelines are presented in this paper. The first is a case study of 1,2,3-trichloropropane, as an example of a chemical with a mutagenic mode of carcinogenic action thus warranting the application of age-dependent adjustment factors for early-life exposure; the second is a case study of ethylene glycol monobutyl ether, as an example of a chemical with a carcinogenic action consistent with a nonlinear extrapolation approach. The use of physiologically based pharmacokinetic (PBPK) modeling to quantify interindividual variability and account for human parameter uncertainty as part of a quantitative cancer assessment is illustrated using a case study involving probabilistic PBPK modeling for dichloromethane. We also discuss statistical issues in assessing trends and model fit for tumor dose-response data, analysis of the combined risk from multiple types of tumors, and application of life-table methods for using human data to derive cancer risk estimates. These issues reflect the complexity and challenges faced in assessing the carcinogenic risks from exposure to environmental chemicals, and provide a view of the current trends in IRIS carcinogenicity risk assessment.

    The U.S. Environmental Protection Agency (EPA) Superfund program's six Preliminary Remediation Goal (PRG) and Dose Compliance Concentration (DCC) internet based calculators for risk and dose assessment at Superfund sites are being revised to reflect better science, revisions to existing exposure scenarios and new scenarios, and changes to match up more closely with the EPA chemical regional screening level calculator. A revised version of the 1999 guidance document that provides an overview for the Superfund risk assessment process at radioactively contaminated sites, 'Radiation Risk Assessment At CERCLA Sites: Q and A', is being completed that will reflect Superfund recommended guidance and other technical documents issued over the past 13 years. EPA is also issuing a series of fact sheets in the document 'Superfund Radiation Risk Assessment: A Community Tool-kit'. This presentation would go over those changes that are expected to be finished by this spring. (authors)

    SciTech Connect

    Stackelberg, K. von; Burmaster, D.E. )

    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.

  15. U.S. EPA Superfund Program's Policy for Risk and Dose Assessment

    SciTech Connect

    Walker, Stuart

    2008-01-15

    The Environmental Protection Agency (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI) has primary responsibility for implementing the long-term (non-emergency) portion of a key U.S. law regulating cleanup: the Comprehensive Environmental Response, Compensation and Liability Act, CERCLA, nicknamed 'Superfund'. The purpose of the Superfund program is to protect human health and the environment over the long term from releases or potential releases of hazardous substances from abandoned or uncontrolled hazardous waste sites. The focus of this paper is on risk and dose assessment policies and tools for addressing radioactively contaminated sites by the Superfund program. EPA has almost completed two risk assessment tools that are particularly relevant to decommissioning activities conducted under CERCLA authority. These are the: 1. Building Preliminary Remediation Goals for Radionuclides (BPRG) electronic calculator, and 2. Radionuclide Outdoor Surfaces Preliminary Remediation Goals (SPRG) electronic calculator. EPA developed the BPRG calculator to help standardize the evaluation and cleanup of radiologically contaminated buildings at which risk is being assessed for occupancy. BPRGs are radionuclide concentrations in dust, air and building materials that correspond to a specified level of human cancer risk. The intent of SPRG calculator is to address hard outside surfaces such as building slabs, outside building walls, sidewalks and roads. SPRGs are radionuclide concentrations in dust and hard outside surface materials. EPA is also developing the 'Radionuclide Ecological Benchmark' calculator. This calculator provides biota concentration guides (BCGs), also known as ecological screening benchmarks, for use in ecological risk assessments at CERCLA sites. This calculator is intended to develop ecological benchmarks as part of the EPA guidance 'Ecological Risk Assessment Guidance for Superfund: Process for Designing and Conducting Ecological Risk

  2. A review and critique of U.S. EPA's risk assessments for asbestos.

    PubMed

    Moolgavkar, Suresh H; Anderson, Elizabeth L; Chang, Ellen T; Lau, Edmund C; Turnham, Paul; Hoel, David G

    2014-07-01

    U.S. Environmental Protection Agency (EPA) recently conducted a risk assessment for exposure to Libby amphibole asbestos that is precedent-setting for two reasons. First, the Agency has not previously conducted a risk assessment for a specific type of asbestos fiber. Second, the risk assessment includes not only an inhalation unit risk (IUR) for the cancer endpoints, but also a reference concentration (RfC) for nonmalignant disease. In this paper, we review the procedures used by the Agency for both cancer and nonmalignant disease and discuss the strengths and limitations of these procedures. The estimate of the RfC uses the benchmark dose method applied to pleural plaques in a small subcohort of vermiculite workers in Marysville, Ohio. We show that these data are too sparse to inform the exposure-response relationship in the low-exposure region critical for estimation of an RfC, and that different models with very different exposure-response shapes fit the data equally well. Furthermore, pleural plaques do not represent a disease condition and do not appear to meet the EPA's definition of an adverse condition. The estimation of the IUR for cancer is based on a subcohort of Libby miners, discarding the vast majority of lung cancers and mesotheliomas in the entire cohort and ignoring important time-related factors in exposure and risk, including effect modification by age. We propose that an IUR based on an endpoint that combines lung cancer, mesothelioma, and nonmalignant respiratory disease (NMRD) in this cohort would protect against both malignant and nonmalignant disease. However, the IUR should be based on the entire cohort of Libby miners, and the analysis should properly account for temporal factors. We illustrate our discussion with our own independent analyses of the data used by the Agency. PMID:24806876

    1987-01-01

    In January 1986 the U.S. Environmental Protection Agency (EPA) adopted a Wetlands Research Plan (Zedler and Kentula 1986). The plan describes the research necessary to assist the Agency in implementing its responsibilities for protecting wetlands, including Section 404 of the Clean Water Act. Three research needs were identified and an emphasis on freshwater systems was recommended. Research will be implemented to: (1) assess the water quality functions of wetlands; (2) develop methods to predict the cumulative impact(s) associated with wetland loss; and (3) improve the formulation and evaluation of wetland creation/ restoration projects required as mitigation for unavoidable impacts.

  5. U.S. EPA Authority to Use Cumulative Risk Assessments in Environmental Decision-Making

    PubMed Central

    Alves, Sarah; Tilghman, Joan; Rosenbaum, Arlene; Payne-Sturges, Devon C.

    2012-01-01

    Conventionally, in its decision-making, the U.S. EPA has evaluated the effects and risks associated with a single pollutant in a single exposure medium. In reality, people are exposed to mixtures of pollutants or to the same pollutant through a variety of media, including the air, water, and food. It is now more recognized than before that environmental exposure to pollutants occurs via multiple exposure routes and pathways, including inhalation, ingestion, and dermal absorption. Moreover, chemical, biologic, radiologic, physical, and psychologic stressors are all acknowledged as affecting human health. Although many EPA offices attempt to consider cumulative risk assessment and cumulative effects in various ways, there is no Agency-wide policy for considering these risks and the effects of exposure to these risks when making environmental decisions. This article examines how U.S. courts might assess EPA’s general authority and discretion to use cumulative risk assessment as the basis for developing data in support of environmental decision-making, and how courts might assess the validity of a cumulative risk assessment methodology itself.

    1990-12-31

    The Environmental Protection Agency of the State of Illinois (Illinois EPA) has programs in water, air, and land pollution and water supplies paralleling those of the US Environmental Protection Agency (EPA). The organization is part of a tripartite arrangement in which the Pollution Control Board is the judicial arm, the Department of Energy and Natural Resources is the research arm, and the Illinois EPA is the enforcement arm. Other state agencies are also concerned with various aspects of the environment and may do risk assessments for chemicals. Although there are various risk assessment activities, both formal and informal, in our agency and in others, this paper will discuss only recent initiatives in water quality criteria.

  12. A comparison of radiological risk assessment models: Risk assessment models used by the BEIR V Committee, UNSCEAR, ICRP, and EPA (for NESHAP)

    SciTech Connect

    Wahl, L.E.

    1994-03-01

    Radiological risk assessments and resulting risk estimates have been developed by numerous national and international organizations, including the National Research Council`s fifth Committee on the Biological Effects of Ionizing Radiations (BEIR V), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and the International Commission on Radiological Protection (ICRP). A fourth organization, the Environmental Protection Agency (EPA), has also performed a risk assessment as a basis for the National Emission Standards for Hazardous Air Pollutants (NESHAP). This paper compares the EPA`s model of risk assessment with the models used by the BEIR V Committee, UNSCEAR, and ICRP. Comparison is made of the values chosen by each organization for several model parameters: populations used in studies and population transfer coefficients, dose-response curves and dose-rate effects, risk projection methods, and risk estimates. This comparison suggests that the EPA has based its risk assessment on outdated information and that the organization should consider adopting the method used by the BEIR V Committee, UNSCEAR, or ICRP.

    Crumpler, E.P.; Rubin, A.B.; Bostian, H.E.

    1988-11-01

    This report describes a potential regulatory approach that the U.S. EPA could use for controlling sewage-sludge incinerators. The approach utilizes a most-exposed individual risk assessment to ensure that sludge-incineration air emissions will not cause an unacceptable health risk. An incinerator facility can demonstrate compliance using a three-tiered system which proceeds from a simple worst case calculation to a more resource intensive site-specific demonstration. A key part of the tiering system is development of an accurate and reliable emissions data base for U.S. sludge incinerators that can be used to develop reasonable worst case emission-control factors. The results of testing to date are discussed in the paper.

  19. Use of genetic toxicology data in U.S. EPA risk assessment: the mercury study report as an example.

    PubMed Central

    Schoeny, R

    1996-01-01

    Assessment of human health risks of environmental agents has often been limited to consideration of the potential for the agent to cause cancer or general systemic toxicity after long-term exposure. The U.S. Environmental Protection Agency (U.S. EPA) is increasingly moving toward the development of integrated assessments, which consider all potential health end points including developmental toxicity, neurotoxicity, immunotoxicity, reproductive effects, and germ cell mutagenicity. The U.S. EPA has a responsibility to assess risks to nonhuman species or ecosystems when appropriate data are available. An example of a recent integrated human health and ecological risk assessment can be found in the U.S. EPA Mercury Study Report to Congress. This report covers the following topics in separate volumes: an inventory of anthropogenic mercury emissions in the United States; an exposure assessment using measured and predicted values and including indirect dietary exposure; an evaluation of human health risks; an assessment of ecologic risk wherein water criteria are presented for several wildlife species; an overall integrated characterization of human and nonhuman risk; and a discussion of risk management considerations. In the evaluation of human health risk, genetic toxicology data were considered for three forms of mercury: elemental, inorganic (divalent), and methylmercury. These data were used in judgments of two types of potential health effects (carcinogenicity and germ cell mutagenicity). In assessment of potential carcinogenicity of inorganic and methylmercury, genetic toxicity data were key. Data for clastogenicity in the absence of mutagenicity supported the characterization of inorganic and methylmercury as materials that produce carcinogenic effects only at high, toxic doses. The evidence for clastogenicity, coupled with information on metabolism and distribution, resulted in a judgment of a moderate degree of concern (or weight of evidence) that inorganic

This includes a review of the EPA’s justification for 2 using a dose-to-risk conversion factor to reduce the dose-based protective ARAR from 15 to 12 mrem/yr. Second, the models and parameters used in RESRAD and the EPA PRG and DCC Calculators are compared in detail, and the results are summarized and discussed. Although there are suites of software tools in the RESRAD family of codes and the EPA Calculators, the scope of this report is limited to the RESRAD (onsite) code for soil contamination and the EPA’s PRG and DCC Calculators also for soil contamination.

    The U.S. Environmental Protection Agency (U.S. EPA) has advocated the establishment of general and scientific guidelines for the evaluation of toxicological data and their use in deriving benchmark values to protect exposed populations from adverse health effects. The Agency's reference dose (RfD) methodology for deriving benchmark values for noncancer toxicity originally addressed risk assessment of oral exposures. This paper presents a brief background on the development of the inhalation reference dose (RfDi) methodology, including concepts and issues related to addressing the dynamics of the respiratory system as the portal of entry. Different dosimetric adjustments are described that were incorporated into the methodology to account for the nature of the inhaled agent (particle or gas) and the site of the observed toxic effects (respiratory or extra-respiratory). Impacts of these adjustments on the extrapolation of toxicity data of inhaled agents for human health risk assessment and future research directions are also discussed.

  13. 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

    The field of toxicology is on the cusp of a major transformation in how the safety and hazard of chemicals are evaluated for potential effects on human health and the environment. Brought on by the recognition of the limitations of the current paradigm in terms of cost, time, and throughput, combined with the ever increasing power of modern biological tools to probe mechanisms of chemical-biological interactions at finer and finer resolutions, 21st century toxicology is rapidly taking shape. A key element of the new approach is a focus on the molecular and cellular pathways that are the targets of chemical interactions. By understanding toxicity in this manner, we begin to learn how chemicals cause toxicity, as opposed to merely what diseases or health effects they might cause. This deeper understanding leads to increasing confidence in identifying which populations might be at risk, significant susceptibility factors, and key influences on the shape of the dose-response curve. The U. S. Environmental Protection Agency (EPA) initiated the ToxCast, or "toxicity forecaster", program 5 years ago to gain understanding of the strengths and limitations of the new approach by starting to test relatively large numbers (hundreds) of chemicals against an equally large number of biological assays. Using computational approaches, the EPA is building decision support tools based on ToxCast in vitro screening results to help prioritize chemicals for further investigation, as well as developing predictive models for a number of health outcomes. This perspective provides a summary of the initial, proof of concept, Phase I of ToxCast that has laid the groundwork for the next phases and future directions of the program. PMID:22519603

  16. Assessment of potential risk levels associated with U.S. Environmental Protection Agency reference values.

    PubMed Central

    Castorina, Rosemary; Woodruff, Tracey J

    2003-01-01

    The U.S. Environmental Protection Agency (U.S. EPA) generally uses reference doses (RfDs) or reference concentrations (RfCs) to assess risks from exposure to toxic substances for noncancer health end points. RfDs and RfCs are supposed to represent lifetime inhalation or ingestion exposure with minimal appreciable risk, but they do not include information about the estimated risk from exposures equal to the RfD/RfC. We used results from benchmark dose modeling approaches recently adopted for use in developing RfDs/RfCs to estimate the risk levels associated with exposures at the RfD/RfC. We searched the U.S. EPA Integrated Risk Information System (IRIS) database and identified 11 chemicals with oral RfDs and 12 chemicals with inhalation RfCs that used benchmark dose modeling. For assessments with sufficient model information, we found that 16 of 21 (76%) of the dose-response models were linear or supralinear. We estimated the risk from exposures at the established RfDs and RfCs for these chemicals using a linear dose-response curve to characterize risk below the observed data. Risk estimates ranged from 1 in 10,000 to 5 in 1,000 for exposures at the RfDs, and from 1 in 10,000 to 3 in 1,000 for exposures at the RfCs. Risk estimates for exposures at the RfD/RfC values derived from sublinear dose-response curves ranged from 3 in 1,000,000,000 to 8 in 10,000. Twenty-four percent of reference values corresponded to estimated risk levels greater than 1 in 1,000; 10 of 14 assessments had points of departure greater than the no-observed-adverse-effect levels. For policy development regarding management of cancer risks, the U.S. EPA often uses 1 in 1,000,000 as a de minimis risk level. Although noncancer outcomes may in some instances be reversible and considered less severe than cancer, our findings call into question the assumption that established RfD and RfC values represent negligibly small risk levels.

    This report estimates risks to workers and the public associated with treatment processes and their associated waste products that would be mandated under proposed regulations of radium, radon, and uranium in drinking water. Three scenarios were examined: (1) all wastes flushed to the sanitary sewer; (2) all wastes disposed on land; (3) similar to (2) but radon removal by granulated activated carbon rather than packed tower aeration. Risks considered included accidental injury and cancer. Worker risks for both scenarios I and II were estimated to be 0.025 and 0.01 deaths per year of operation for radium-226 and radium-228, respectively. Worker risks for uranium were estimated to be 0.13 deaths/year of operation for scenario I and 0.5 deaths/year of operation for scenario II. Worker risks for radon removal were estimated to be 1.7 deaths/year of operation for scenario I and 2.2 deaths/year of operation for scenario II. Risks to the public for scenarios I and II for radium-226 were 4 {times} 10{sup {minus}4} and for radium-228 were 9 {times} 10{sup {minus}5} deaths/year of operation. Risks to the public for scenarios I and II for uranium were 7.3 {times} 10{sup {minus}2} and 2 {times} 10{sup {minus}4}, respectively. Risks to the public for scenario I and II for radon were 24 deaths/year of operation and for scenario III were nil. Public risks were quantified only for people exposed during a year of operation. For example, effects of public exposures in future years via groundwater contamination associated with landfill of treatment waste were not considered.

  2. The use and acceptance of Other Scientifically Relevant Information (OSRI) in the U.S. Environmental Protection Agency (EPA) Endocrine Disruptor Screening Program.

    PubMed

    Bishop, Patricia L; Willett, Catherine E

    2014-02-01

    The U.S. Environmental Protection Agency (EPA) Endocrine Disruptor Screening Program (EDSP) currently relies on an initial screening battery (Tier 1) consisting of five in vitro and six in vivo assays to evaluate a chemical's potential to interact with the endocrine system. Chemical companies may request test waivers based on Other Scientifically Relevant Information (OSRI) that is functionally equivalent to data gathered in the screening battery or that provides information on a potential endocrine effect. Respondents for 47 of the first 67 chemicals evaluated in the EDSP submitted OSRI in lieu of some or all Tier 1 tests, seeking 412 waivers, of which EPA granted only 93. For 20 of the 47 chemicals, EPA denied all OSRI and required the entire Tier 1 battery. Often, the OSRI accepted was either identical to data generated by the Tier 1 assay or indicated a positive result. Although identified as potential sources of OSRI in EPA guidance, Part 158 guideline studies for pesticide registration were seldom accepted by EPA. The 93 waivers reduced animal use by at least 3325 animals. We estimate 27,731 animals were used in the actual Tier 1 tests, with additional animals being used in preparation for testing. Even with EPA's shift toward applying 21st-century toxicology tools to screening of endocrine disruptors in the future, acceptance of OSRI will remain a primary means for avoiding duplicative testing and reducing use of animals in the EDSP. Therefore, it is essential that EPA develop a consistent and transparent basis for accepting OSRI. PMID:24151143

  12. The differential effects of EPA and DHA on cardiovascular risk factors.

    PubMed

    Cottin, S C; Sanders, T A; Hall, W L

    2011-05-01

    Compelling evidence exists for the cardioprotective benefits resulting from consumption of fatty acids from fish oils, EPA (20:5n-3) and DHA (22:6n-3). EPA and DHA alter membrane fluidity, interact with transcription factors such as PPAR and sterol regulatory element binding protein, and are substrates for enzymes including cyclooxygenase, lipoxygenase and cytochrome P450. As a result, fish oils may improve cardiovascular health by altering lipid metabolism, inducing haemodynamic changes, decreasing arrhythmias, modulating platelet function, improving endothelial function and inhibiting inflammatory pathways. The independent effects of EPA and DHA are poorly understood. While both EPA and DHA decrease TAG levels, only DHA appears to increase HDL and LDL particle size. Evidence to date suggests that DHA is more efficient in decreasing blood pressure, heart rate and platelet aggregation compared to EPA. Fish oil consumption appears to improve arterial compliance and endothelial function; it is not yet clear as to whether differences exist between EPA and DHA in their vascular effects. In contrast, the beneficial effect of fish oils on inflammation and insulin sensitivity observed in vitro and in animal studies has not been confirmed in human subjects. Further investigation to clarify the relative effects of consuming EPA and DHA at a range of doses would enable elaboration of current understanding regarding cardioprotective effects of consuming oily fish and algal sources of long chain n-3 PUFA, and provide clearer evidence for the clinical therapeutic potential of consuming either EPA or DHA-rich oils.

    1996-02-01

    This Record of Decision (ROD) documents the U.S. Environmental Protection Agency`s (EPA`s) selection of the remedial action for the Anchor Chemical Superfund Site (the `Site`). EPA, in consultation with the State of New York, has determined that the Achor Chemical Superfund Site does not pose a significant threat to human health or the environment and, therefore, further remediation is not appropriate. This determination is based on the findings of the Remedial Investigation and the baseline Risk Assessment. The risks posed by the Site are within EPA`s acceptable risk range and therefore do not pose a threat to human health or the environment.

  5. Agency, reflexivity and risk: cosmopolitan, neurotic or prudential citizen?

    PubMed

    Walklate, Sandra; Mythen, Gabriel

    2010-03-01

    The purpose of this paper is to critically examine the turn to risk within sociology and to survey the relationship between structure and agency as conceived by popular strands of risk theorizing. To this end, we appraise the risk society, culture of fear and governmentality perspectives and we consider the different imaginings of the citizen constructed by each of these approaches. The paper goes on to explore what each of these visions of citizenship implies for understandings of the structure/agency dynamic as it pertains to the question of reflexivity. In order to transcend uni-dimensional notions of citizenship and to reinvigorate sociological debates about risk, we call for conceptual analyses that are contextually rooted. Exampling the importance of knowledge contests around contemporary security threats and warnings of the deleterious effects of pre-emptive modes of regulation that derive from the 'risk turn' within social science, we argue for a more nuanced embrace of reflexivity within risk theorising in order to facilitate a more dynamic critique of the images of citizenship that such theorizing promotes.

    PubMed

    Jarabek, A M; Menache, M G; Overton, J H; Dourson, M L; Miller, F J

    1990-10-01

    The U.S. Environmental Protection Agency (U.S. EPA) has advocated the establishment of general and scientific guidelines for the evaluation of toxicological data and their use in deriving benchmark values to protect exposed populations from adverse health effects. The Agency's reference dose (RfD) methodology for deriving benchmark values for noncancer toxicity originally addressed risk assessment of oral exposures. This paper presents a brief background on the development of the inhalation reference dose (RfDi) methodology, including concepts and issues related to addressing the dynamics of the respiratory system as the portal of entry. Different dosimetric adjustments are described that were incorporated into the methodology to account for the nature of the inhaled agent (particle or gas) and the site of the observed toxic effects (respiratory or extrarespiratory). Impacts of these adjustments on the extrapolation of toxicity data of inhaled agents for human health risk assessment and future research directions are also discussed. PMID:1670284

    Make a full investigation of the policy implications and appropriate uses of risk assessment and risk management in regulatory programs under various Federal laws to prevent cancer and other chronic health effects which may result from exposure to hazardous substances. This is the primary mission of the Risk Assessment and Management Commission (Risk Commission). The Clean Air Act Amendments of 1990 (CAAA), created the Risk Commission reflecting Congress' concern over agency use of risk assessment and risk management techniques and methodologies to implement federal laws protective of human health. The Risk Commission is to consider: methods for measuring and describing risks of chronic health effects from hazardous substances; methods to reflect uncertainties associated with estimation techniques, and whether it is possible or desirable to develop a consistent risk assessment methodology or a consistent standard of acceptable risk for various federal programs.

    2008-09-01

    Nanotechnologies have been called the "Next Industrial Revolution." At the same time, scientists are raising concerns about the potential health and environmental risks related to the nano-sized materials used in nanotechnologies. Analyses suggest that current U.S. federal regulatory structures are not likely to adequately address these risks in a proactive manner. Given these trends, the premise of this paper is that state and local-level agencies will likely deal with many "end-of-pipe" issues as nanomaterials enter environmental media without prior toxicity testing, federal standards, or emissions controls. In this paper we (1) briefly describe potential environmental risks and benefits related to emerging nanotechnologies; (2) outline the capacities of the Toxic Substances Control Act, the Clean Air Act, the Clean Water Act, and the Resources Conservation and Recovery Act to address potential nanotechnology risks, and how risk data gaps challenge these regulations; (3) outline some of the key data gaps that challenge state-level regulatory capacities to address nanotechnologies' potential risks, using Wisconsin as a case study; and (4) discuss advantages and disadvantages of state versus federal approaches to nanotechnology risk regulation. In summary, we suggest some ways government agencies can be better prepared to address nanotechnology risk knowledge gaps and risk management. PMID:18543023

    SciTech Connect

    Reasoner, D.J.; Rice, E.W.

    1989-01-01

    The biological stability of treated drinking water has become a major concern for water utilities. The U.S. E.P.A. is concerned from the perspective of coliform MCL compliance and remediation of coliform biofilm problems. The levels of readily assimilable nutrients present in treated water are affected by water treatment processes, but of greatest concern are those processes, such as ozonation, that cause increases in the levels of assimilable organic carbon (AOC) and therefore contribute to biological instability of the water. Thus, the combined use of ozonation (pre-oxidant) and a lower disinfectant residual as an approach to reducing disinfectant byproducts may result in increased bacterial growth, including coliforms, in the distribution system. Information is needed on: the AOC flux level that stimulate coliform growth in biofilm: the specific nutrients and concentrations that can stimulate growth of both coliforms and HPC; treatment strategies to reduce AOC levels and strategies to effectively control biofilm formation where AOC levels cannot be reduced.

  18. Overview of ozone human exposure and health risk analyses used in the U.S. EPA's review of the ozone air quality standard.

    SciTech Connect

    Whitfield, R. G.

    1999-03-04

    This paper presents an overview of the ozone human exposure and health risk analyses developed under sponsorship of the U.S. Environmental Protection Agency (EPA). These analyses are being used in the current review of the national ambient air quality standards (NAAQS) for ozone. The analyses consist of three principal steps: (1) estimating short-term ozone exposure for particular populations (exposure model); (2) estimating population response to exposures or concentrations (exposure-response or concentration-response models); and (3) integrating concentrations or exposure with concentration-response or exposure-response models to produce overall risk estimates (risk model). The exposure model, called the probabilistic NAAQS exposure model for ozone (pNEM/03), incorporates the following factors: hourly ambient ozone concentrations; spatial distribution of concentrations; ventilation state of individuals at time of exposure; and movement of people through various microenvironments (e.g., outdoors, indoors, inside a vehicle) of varying air quality. Exposure estimates are represented by probability distributions. Exposure-response relationships have been developed for several respiratory symptom and lung function health effects, based on the results of controlled human exposure studies. These relationships also are probabilistic and reflect uncertainties associated with sample size and variability of response among subjects. The analyses also provide estimates of excess hospital admissions in the New York City area based on results from an epidemiology study. Overall risk results for selected health endpoints and recently analyzed air quality scenarios associated with alternative 8-hour NAAQS and the current 1-hour standard for outdoor children are used to illustrate application of the methodology.

  19. Dietary reference intakes for DHA and EPA.

    PubMed

    Kris-Etherton, Penny M; Grieger, Jessica A; Etherton, Terry D

    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.

    1987-04-29

    Traditionally, the oral route has been the most common route of administration in bioassays which tested the potential carcinogenicity of chemicals. Regulatory agencies, however, prefer to have test chemicals applied by the same route as expected human exposure, whenever possible. Since human exposure to industrial chemicals is frequently via the dermal route, this has become a route of choice for animal testing of certain chemicals. However, protocol design for dermal bioassays presents many unique problems which must be addressed before guidelines for bioassays by the dermal route can be formulated. Furthermore, it may be feasible to develop a limited dermal protocol to screen certain classes of chemicals such as acrylates/methacrylates. Recognizing the need for this workshop, it was designed in two distinct parts; to address the problems inherent in the development of a generic protocol for dermal bioassays and, a specific limited dermal bioassay protocol for acrylates/methacrylates.

    Computational toxicology combines data from high-throughput test methods, chemical structure analyses and other biological domains (e.g., genes, proteins, cells, tissues) with the goals of predicting and understanding the underlying mechanistic causes of chemical toxicity and for predicting toxicity of new chemicals and products. A key feature of such approaches is their reliance on knowledge extracted from large collections of data and data sets in computable formats. The U.S. Environmental Protection Agency (EPA) has developed a large data resource called ACToR (Aggregated Computational Toxicology Resource) to support these data-intensive efforts. ACToR comprises four main repositories: core ACToR (chemical identifiers and structures, and summary data on hazard, exposure, use, and other domains), ToxRefDB (Toxicity Reference Database, a compilation of detailed in vivo toxicity data from guideline studies), ExpoCastDB (detailed human exposure data from observational studies of selected chemicals), and ToxCastDB (data from high-throughput screening programs, including links to underlying biological information related to genes and pathways). The EPA DSSTox (Distributed Structure-Searchable Toxicity) program provides expert-reviewed chemical structures and associated information for these and other high-interest public inventories. Overall, the ACToR system contains information on about 400,000 chemicals from 1100 different sources. The entire system is built using open source tools and is freely available to download. This review describes the organization of the data repository and provides selected examples of use cases. PMID:22408426

  8. EPA Hearing Sparks Controversy

    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.

    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

    Human beings are frequently exposed to pathogens and heavy metals through ingestion of contaminated drinking water throughout the world particularly in developing countries. The present study aimed to assess the quality of water used for drinking purposes in Malakand Agency, Pakistan. Water samples were collected from different sources (dug wells, bore wells, tube wells, springs, and hand pumps) and analyzed for different physico-chemical parameters and bacterial pathogens (fecal coliform bacteria) using standard methods, while heavy metals were analyzed using atomic absorption spectrophotometry (AAS-PEA-700). In the study area, 70 % of water sources were contaminated with F. coliform representing high bacterial contamination. The heavy metals, such as Cd (29 and 8 %), Ni (16 and 78 %), and Cr (7 %), exceeded their respective safe limits of WHO (2006) and Pak-EPA (2008), respectively, in water sources, while Pb (9 %) only exceeded from WHO safe limit. The risk assessment tools such as daily intake of metals (DIMs) and health risk indexes (HRIs) were used for health risk estimation and were observed in the order of Ni > Cr > Mn > Pb > Cd and Cd > Ni > Pb > Mn > Cr, respectively. The HRI values of heavy metals for both children and adults were <1, showing lack of potential health risk to the local inhabitants of the study area. PMID:27075311

    Cardiovascular (CV) risk may remain despite statin treatment, and there is a need to address this risk with add-on therapy. The lipid effects of two different prescription omega-3 fatty acid therapies are described in a 55-year-old statin- and niacin-treated female with severe dyslipidemia and high CV risk. The patient was initially treated with omega-3-acid ethyl esters (eicosapentaenoic acid [EPA] and docosahexaenoic acid) 4 g/day. Due to persistently elevated low-density lipoprotein cholesterol (LDL-C), she was switched to icosapent ethyl (high-purity EPA ethyl ester) 4 g/day. Approximately 28 months after switching to icosapent ethyl, her LDL-C decreased by 69% to 52 mg/dL, triglycerides decreased by 35% to 119 mg/dL, non-high-density lipoprotein cholesterol (non-HDL-C) decreased by 63% to 76 mg/dL, total cholesterol decreased by 44% to 137 mg/dL, and HDL-C increased by 45% to 61 mg/dL. Total and small dense LDL particle concentrations decreased by 60 and 59%, respectively. Treatment was well tolerated, with improvements maintained over two years. PMID:27478390

    Single point estimates of human health hazard/toxicity values such as a reference dose (RfD) are generally used in chemical hazard and risk assessment programs for assessing potential risks associated with site- or use-specific exposures. The resulting point estimates are often used by risk managers for regulatory decision-making, including standard setting, determination of emission controls, and mitigation of exposures to chemical substances. Risk managers, as well as stakeholders (interested and affected parties), often have limited information regarding assumptions and uncertainty factors in numerical estimates of both hazards and risks. Further, the use of different approaches for addressing uncertainty, which vary in transparency, can lead to a lack of confidence in the scientific underpinning of regulatory decision-making. The overarching goal of this paper, which was developed from an invited participant workshop, is to offer five approaches for presenting toxicity values in a transparent manner in order to improve the understanding, consideration, and informed use of uncertainty by risk assessors, risk managers, and stakeholders. The five approaches for improving the presentation and communication of uncertainty are described using U.S. Environmental Protection Agency's (EPA's) Integrated Risk Information System (IRIS) as a case study. These approaches will ensure transparency in the documentation, development, and use of toxicity values at EPA, the Agency for Toxic Substances and Disease Registry (ATSDR), and other similar assessment programs in the public and private sector. Further empirical testing will help to inform the approaches that will work best for specific audiences and situations. PMID:26827183

    This document announces the conclusions of the EPA evaluation of the 'Super-Mag Fuel Extender' device under provisions of Section 511 of the Motor Vehicle Information and Cost Savings Act. On December 10, 1980, the EPA received a written request from the Metropolitan Denver District Attorney's Office of Consumer Fraud and Economic Crime to test at least one 'cow magnet' type of fuel economy device. Following a survey of devices being marketed, the Metropolitan Denver District Attorney's Office selected the 'Super-Mag' device as typical of its category and on April 13, 1981 provided EPA with units for testing. The EPA evaluation of the device using three vehicles showed neither fuel economy nor exhaust emissions were affected by the installation of the 'Super-Mag' device. In addition, any differences between baseline test results and results from tests with the device installed were within the range of normal test variability.

  6. The tobacco industry's political efforts to derail the EPA report on ETS.

    PubMed

    Muggli, Monique E; Hurt, Richard D; Repace, James

    2004-02-01

    Previously secret tobacco industry documents detailed a multifaceted approach of political strategies aimed to derail the 1993 Environmental Protection Agency (EPA) risk assessment on environmental tobacco smoke (ETS). These pervasive strategies included the following: (1) lobbying the first Bush Administration to approve an executive order that would impose new risk assessment standards for federal agencies, thus delaying the release of the EPA report; (2) having the first Bush Administration transfer jurisdiction over ETS from the EPA to Occupational Safety and Health Administration (OSHA), thus obviating the need for the release of the EPA report; and (3) applying enormous political pressure directly by alleging improper procedure and policy at EPA. Although some of the attempted strategies failed, the political pressure from Congressman Thomas Bliley (R-VA) was a success. This is the first report showing how a single member of Congress in conjunction with his staff, tobacco industry attorneys, and executives worked very aggressively to do the tobacco industry's bidding. These tactics successfully delayed the EPA risk assessment and placed a cloud over its validity that was not fully vindicated until December 2002 when the U.S. 4th Circuit Court of Appeals overturned the tobacco industry's suit against the EPA. The documents show that the industry will expend whatever effort is necessary to protect itself from public health policy that would adversely affect consumption of cigarettes and, therefore, profit.

    1983-05-01

    This report announces the conclusions of the EPA evaluation of the Optimizer device under the provisions of section 511 of the Motor Vehicle Information and Cost Savings Act. The evaluation of the Optimizer was conducted upon the application of the manufacturer. The basic device is a combustion catalyst consisting of an electric fuel heater containing a bed of platinum deposited on an inert substrate. The remainder of the system includes a heater relay, a condenser to cool the fuel to operating temperature, and the associated plumbing. According to the applicant, the device introduces a very small amount of platinum into the fuel. This enhances the combustion process and allows ignition timing to be advanced. The device, coupled with the ignition timing adjustments, is claimed to improve fuel economy, increase performance, and reduce engine maintenance while keeping emissions low. EPA fully considered all of the information submitted by the applicant. The evaluation of the Optimizer device was based on that information and EPA's engineering judgement. The overall conclusion is that, for most vehicles, the device and the prescribed ignition timing adjustments of the engine will cause a small improvement in fuel economy and a large increase in NOx (oxides of nitrogen) emissions.

    1982-02-25

    On May 19, 1980, EPA promulgated regulations applicable to owners and operators of hazardous waste treatment, storage, and disposal facilities which prohibited the landfill disposal of most containerized liquid waste or waste containing free liquid on and after November 19, 1981. Further on June 29, 1981, EPA amended its hazardous waste management regulations so as to extend the compliance date of the restriction on the landfill disposal of containerized liquid ignitable wastes to coincide with the compliance data of the general restriction on landfill disposal of liquids. The Agency is today extending the compliance date on both these requirements until May 26, 1982, and, in a separate action, is proposing amendments to these restrictions. This extension of compliance dates is provided for the sole purpose of allowing time to complete the rulemaking action on today's proposed amendments. The Agency is also today exempting from the requirements of the hazardous waste management regulations, the acts of adding absorbent material to hazardous waste in containers and adding hazardous waste to absorbent material in a container, at the time waste is first placed in the container, in order to reduce the free liquids in a container.

    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.

    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.

    Waldman, D.J.; Gladden, J.R.; Endicott, D.L.; Cull, B.A.

    1989-01-01

    The emissions of a lean-burn natural-gas-fueled 3406 spark-ignited engine were determined on the EPA transient emission cycle for heavy-duty vehicle engines. The engine was rated at 350 hp at 1800 rpm. The engine was a minimally modified generator-set engine developed under the same GRI contract and was not optimized for truck applications or transient emissions. Transient emissions in g/hp-hr were 4.1 NOx, 9.2 total hydrocarbons, 0.84 non-methane hydrocarbons, 3.2 CO, 0.42 aldehydes, and 0.60 particulates. Steady-state emissions were also measured. The results indicate lean-burn spark-ignited engine technology is a promising approach to meeting 1994 EPA truck-engine-emission standards. NOx and CO standards can be readily met. Hydrocarbon emissions exceed the standard in the engine as presently configured but are believed to be controllable by improved air/fuel ratio control, combustion-system modification and/or an oxidation catalyst. The particulates were primarily from the lubricating oil and should be controllable with piston ring and valve-seal improvements and/or an oxidation catalyst.

    The document announces the conclusions of the EPA evaluation of the POLARION-X device under the provisions of Section 511 of the Motor Vehicle Information and Cost Savings Act. The second evaluation of the POLARION-X device was conducted upon receiving an application for evaluation from the marketer of the device. The device is a fuel magnet. It is claimed to reduce emissions, to improve fuel economy and performance, to provide more complete combustion, to eliminate engine carbon buildup and dieseling, and to reduce the octane requirements of the engine. EPA fully considered all of the previous correspondence and analyses that were incorporated in the prior evaluation. In addition, the intervening correspondence about the device and test fuel are also considered to apply to the application. The net result is that, except for the test data, the previous submission and the analyses of it are essentially unchanged. Based on engineering judgment and the results of test data, it is concluded that the POLARION-X device will not improve emissions or fuel economy.

The Dynamix device is claimed to permit an unmodified conventional engine to operate efficiently on a blend of gasoline and hydrous ethyl alcohol. The ratio of gasoline to alcohol is selected by the operator. The device consists of an alcohol fuel storage and handling system, an alcohol/gasoline fuel proportioning valve, and an alcohol/heated air induction system. The Dynamix meters vaporized alcohol and hot air directly into the intake manifold of a vehicle. The flow of gasoline is controlled by the flow of alcohol.

    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.

  19. Building-related symptoms among U.S. office workers and risks factors for moisture and contamination: Preliminary analyses of U.S. EPA BASE Data

    SciTech Connect

    Mendell, Mark J.; Cozen, Myrna

    2002-09-01

    The authors assessed relationships between health symptoms in office workers and risk factors related to moisture and contamination, using data collected from a representative sample of U.S. office buildings in the U.S. EPA BASE study. Methods: Analyses assessed associations between three types of weekly, workrelated symptoms-lower respiratory, mucous membrane, and neurologic-and risk factors for moisture or contamination in these office buildings. Multivariate logistic regression models were used to estimate the strength of associations for these risk factors as odds ratios (ORs) adjusted for personal-level potential confounding variables related to demographics, health, job, and workspace. A number of risk factors were associated (e.g., 95% confidence limits excluded 1.0) significantly with small to moderate increases in one or more symptom outcomes. Significantly elevated ORs for mucous membrane symptoms were associated with the following risk factors: presence of humidification system in good condition versus none (OR = 1.4); air handler inspection annually versus daily (OR = 1.6); current water damage in the building (OR = 1.2); and less than daily vacuuming in study space (OR = 1.2). Significantly elevated ORs for lower respiratory symptoms were associated with: air handler inspection annually versus daily (OR = 2.0); air handler inspection less than daily but at least semi-annually (OR=1.6); less than daily cleaning of offices (1.7); and less than daily vacuuming of the study space (OR = 1.4). Only two statistically significant risk factors for neurologic symptoms were identified: presence of any humidification system versus none (OR = 1.3); and less than daily vacuuming of the study space (OR = 1.3). Dirty cooling coils, dirty or poorly draining drain pans, and standing water near outdoor air intakes, evaluated by inspection, were not identified as risk factors in these analyses, despite predictions based on previous findings elsewhere, except that very

  20. 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.

    Loftin, Keith A.; Graham, Jennifer; Elizabeth Hilborn; Sarah Lehmann; Meyer, Michael T.; Dietze, Julie E.; Griffith, Christopher

    2016-01-01

    A large nation-wide survey of cyanotoxins (1161 lakes) in the United States (U.S.) was conducted during the EPA National Lakes Assessment 2007. Cyanotoxin data were compared with cyanobacteria abundance- and chlorophyll-based World Health Organization (WHO) thresholds and mouse toxicity data to evaluate potential recreational risks. Cylindrospermopsins, microcystins, and saxitoxins were detected (ELISA) in 4.0, 32, and 7.7% of samples with mean concentrations of 0.56, 3.0, and 0.061 mg/L, respectively (detections only). Co-occurrence of the three cyanotoxin classes was rare (0.32%) when at least one toxin was detected. Cyanobacteria were present and dominant in 98 and 76% of samples, respectively. Potential anatoxin-, cylindrospermopsin-, microcystin-, and saxitoxin-producing cyanobacteria occurred in 81, 67, 95, and 79% of samples, respectively. Anatoxin-a and nodularin-R were detected (LC/MS/MS) in 15 and 3.7% samples (n = 27). The WHO moderate and high risk thresholds for microcystins, cyanobacteria abundance, and total chlorophyll were exceeded in 1.1, 27, and 44% of samples, respectively. Complete agreement by all three WHO microcystin metrics occurred in 27% of samples. This suggests that WHO microcystin metrics based on total chlorophyll and cyanobacterial abundance can overestimate microcystin risk when compared to WHO microcystin thresholds. The lack of parity among the WHO thresholds was expected since chlorophyll is common amongst all phytoplankton and not all cyanobacteria produce microcystins.

  17. 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.

  18. EPA requirements and programs

    NASA Technical Reports Server (NTRS)

    Koutsandreas, J. D.

    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.

Also, volatile organic compounds and sulfur emissions could be cut in half, with particulate matter cut by 37%.

  3. Putting the first audience first: conducting useful evaluation for a risk-related government agency.

    PubMed

    Balch, G I; Sutton, S M

    1995-04-01

    The risk communication practitioner in a government agency has two essential, interdependent tasks. One is to help develop and monitor effective communication programs with various external public audiences. The other task is to do the same thing for the senior government managers whose support is a prerequisite to addressing the first audience. Hence, the second audience--the manager--is really the first. This paper addresses ways in which communication practitioners can satisfy this crucial audience. A profile of these managers suggests that they would find it highly beneficial to have more control over the public problems they encounter, especially in view of the growing pressures to do more with less and demonstrate "customer satisfaction." They would rather avoid crises than manage them. And they would rather have their bosses praise their successes than challenge their budgets or punish their perceived difficulties or failures. Communication practitioners who can help them attain such benefits will find their efforts in great demand. They would be helpful team members who provide timely insights that can make and show agency success. We offer ten ways for communication practitioners to be more useful which focus their current strengths on satisfying senior managers' needs by becoming more valuable members of the program team. By becoming more useful to the senior manager they serve both the agency and its publics. PMID:7597254

    Over the next few months, the US Environmental Protection Agency (EPA) will be finalizing its proposal to revise the National Ambient Air Quality Standards (NAAQS) for fine and coarse particulate matter (PM). Since issuing the proposal in December 2005, the agency has sought comments from all interested parties, and will base its final decision on the record that was established through the comment period, which ended on April 17. In this issue articles present perspectives from some of the many non-EPA stakeholders who have played an important role in this review process. This article summarizes EPA's proposal, as well as the extensive process EPA goes through when setting air quality standards. 1 fig., 2 tabs.

    2008-01-01

    NASA's mission is to pioneer the future in space exploration, scientific discovery, and aeronautics research. To help enable existing and future programs to pursue this mission, NASA has established the Principal Center for Regulatory Risk Analysis and Communication (RRAC PC) to proactively identify, analyze, and communicate environmental regulatory risks to the NASA community. The RRAC PC is chartered to evaluate the risks posed to NASA Programs and facilities by environmentally related drivers. The RRAC PC focuses on emerging environmental regulations, as well as risks related to operational changes that can trigger existing environmental requirements. Changing regulations have the potential to directly affect program activities. For example, regulatory changes can restrict certain activities or operations by mandating changes in how operations may be done or limiting where or how certain operations can take place. Regulatory changes also can directly affect the ability to use certain materials by mandating a production phase-out or restricting usage aPi'iications of certain materials. Such changes can result in NASA undertaking material replacement efforts. Even if a regulation does not directly affect NASA operations, U.S. and international regulations can pose program risks indirectly through requirements levied on manufacturers and vendors of components and materials. For example, manufacturers can change their formulations to comply with new regulatory requirements. Such changes can require time-consuming and costly requalification certification for use in human spaceflight programs. The RRAC PC has implemented several strategies for proactively managing regulatory change to minimize potential adverse impacts to NASA Programs and facilities. This presentation highlights the lessons learned through establishing the RRAC PC, the process by which the RRAC PC monitors and distributes information about emerging regulatory requirements, and the cross-Agency

    1999-08-01

    The US EPA integrated Exposure Uptake Biokinetic (IEUBK 0.99d) lead exposure for children was validated, updated, and applied to predict mean blood lead levels based on lead uptake from multiple sources and provide assessment of risk. Surveys were carried out around houses in a polluted area (Heves, Hungary) in 1995. The collected data from that area have shown very high levels of lead in soil. In some cases the level of lead in soil has reached more than 1000 times the allowable limit value used (100 mg/kg) in Hungary. Moreover, the concentration of lead in air was measured and the concentration of lead in air varied from 0.05-1.83 micrograms/m3. The environmental data within the community were used to predict the children blood lead levels and to compare the observed estimates with the other predicted ones. The age of the investigated group of children varied from 0-60 months. The estimated blood lead levels have illustrated variation according to age, sex, and the specific site. It can be concluded from this study that the model can be used on a wide range to give us an excellent picture for site cleanup, to decision makers, and finally to use the environmental data to predict blood lead level for the community or population. Results of several validation exercises utilizing the IEUBK model comparing predicted and measured blood lead levels with international guidelines and the percent of risk of exceeding a specific blood lead level (i.e., 10 micrograms/dl) are presented in this paper.

    1995-12-31

    Under the requirements of the Federal Facility Compliance Act (FFCA), the Department of Energy (DOE) is directed to develop treatment plans for their stockpile of wastes generated at their various sites. As a result, DOE is facing the monumental problem associated with the treatment and ultimate disposal of their mixed (radioactive and hazardous) waste. Meanwhile, the Environmental Protection Agency (EPA) issued a final {open_quotes}Hazardous Waste Combustion Strategy{close_quotes} in November 1994. Under the Combustion Strategy, EPA permit writers have been given the authority to use the Omnibus Provision of the Resource Conservation and Recovery Act (RCRA) to impose more stringent emission limits for waste combustors prior to the development of new regulations. EPA and DOE established a multi-year Interagency Agreement (IAG) in 1991. The main objective of the IAG (and of the second IAG that was added in 1993) is to conduct a research program on thermal technologies for treating mixed waste and to establish permit procedures for these technologies particularly under the new requirements of the above-mentioned EPA Combustion Strategy. The objective of this Paper is to summarize the results of the EPA/DOE joint efforts on mixed waste treatment since the establishment of the original Interagency Agreement. Specifically, this Paper will discuss six activities that have been underway; namely: (1) National Technical Workgroup (NTW) on Mixed Waste Treatment, (2) State-of-the-Art Assessment of APC (Air Pollution Control) and Monitoring Technologies for the Rocky Flats Fluidized Bed Unit, (3) Initial Study of Permit {open_quotes}Roadmap{close_quotes} Development for Mixed Waste Treatment, (4) Risk Assessment Approach for a Mixed Waste Thermal Treatment Facility, (5) Development and Application of Technology Selection Criteria for Mixed Waste Thermal Treatment, and (6) Performance Testing of Mixed Waste Incineration: In-Situ Chlorine Capture in a Fluidized Bed Unit.

    The EPA reports discussed below have recently been made available through the National Technical Information Service (NTIS) or EPA`s Office Research and Development (ORD). Studies were conducted recently to determine the suitability of incineration as a treatment technology for contaminated soils and sludges from three separate Superfund sites. All of the testing was performed at EPA`s incineration research facility in Jefferson, Arkansas. The test system consists of a rotary kiln incinerator, fired afterburner, wet flue gas scrubber (a venturi section in series with a packed column), and various other air pollution control equipment. EPA`s project summaries of the three reports, including results from the pilot-scale incineration tests, are summarized below. 1 fig., 2 tabs.

    quantified: the soil factors (soil sealing, erodibility and runoff), the rate of land cover over three years for each season and for 77 land use classes, the topographic factor (slope and drainage area) and the climate hazard (seasonal amount and rainfall erosivity). These modifications of the original MESALES model allow to better represent erosion risk for arable and bare land. We validated model results by stakeholder consultations and meetings over all the study area. The model has finally been modified taking into account validation results. Results are provided with a spatial resolution of 1 km, and then integrated into 2121 catchments. An erosion risk map for each season and an annual erosion risk map are produced. These new maps allow to organize in hierarchy 2121 catchments into three erosion risk classes. In the annual erosion risk map, 347 catchments have the highest erosion risk, which corresponds to 16 % of total Brittany-Loire basin area. Water management agency now uses these maps to identify priority areas and to plan specific preservation practices.

    In the report, the Science Advisory Board offers a new assessment of environmental problems, based on the comparative risks posed by these problems. The Board further calls for innovative, integrated policies to effectively and efficiently reduce the most serious risks. With its emphasis on preventing pollution before it becomes a problem, on market incentives, on educating, on cooperation among EPA, other agencies, and other sectors of society, reducing risk is already guiding much of what the authors do here at EPA. The advisory committees give sound advice and provides fresh, independent perspectives on business matters at EPA. The five new advisory committees for the year are: The Acid Rain Advisory Committee; The Clean Air Act Advisory Committee; The Environmental Financial Advisory Board; The Lead Acid Battery Recycling Negotiated Rulemaking Advisory Committee; and The Reformulated Gasoline Rule and Oxygenated Gasoline -- Marketable Oxygen Credit Program Guidelines and Labeling Regulations Negotiated Rulemaking Advisory Committee.

  11. Evaluating public participation in environmental decision-making: EPA's superfund community involvement program.

    PubMed

    Charnley, Susan; Engelbert, Bruce

    2005-11-01

    This article discusses an 8-year, ongoing project that evaluates the Environmental Protection Agency's Superfund community involvement program. The project originated as a response to the Government Performance and Results Act, which requires federal agencies to articulate program goals, and evaluate and report their progress in meeting those goals. The evaluation project assesses how effective the Superfund community involvement program is in promoting public participation in decisions about how to clean up hazardous wastes at Superfund sites. We do three things in the article: (1) share our experience with evaluating an Agency public participation program, including lessons learned about methods of evaluation; (2) report evaluation results; and (3) address a number of issues pertaining to the evaluation of public participation in environmental decision-making. Our goal is to encourage more environmental managers to incorporate evaluation into their public participation programs as a tool for improving them. We found that written mail surveys were an effective and economical tool for obtaining feedback on EPA's community involvement program at Superfund sites. The evaluation focused on four criteria: citizen satisfaction with EPA information about the Superfund site, citizen understanding of environmental and human health risks associated with the site, citizen satisfaction with opportunities provided by EPA for community input, and citizen satisfaction with EPA's response to community input. While the evaluation results were mixed, in general, community members who were most informed about and involved in the cleanup process at Superfund sites generally were also the most satisfied with the community involvement process, and the job that EPA was doing cleaning up the site. We conclude that systematic evaluation provides meaningful and useful information that agencies can use to improve their public participation programs. However, there need to be

    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.

    The hypothesis has been put forward that humans and wildlife species adverse suffered adverse health effects after exposure to endocrine-disrupting chemicals. Reported adverse effects include declines in populations, increases in cancers, and reduced reproductive function. The U.S. Environmental Protection Agency sponsored a workshop in April 1995 to bring together interested parties in an effort to identify research gaps related to this hypothesis and to establish priorities for future research activities. Approximately 90 invited participants were organized into work groups developed around the principal reported health effects-carcinogenesis, reproductive toxicity, neurotoxicity, and immunotoxicity-as well as along the risk assessment paradigm-hazard identification, dose-response assessment, exposure assessment, and risk characterization. Attention focused on both ecological and human health effects. In general, group felt that the hypothesis warranted a concerted research effort to evaluate its validity and that research should focus primarily on effects on development of reproductive capability, on improved exposure assessment, and on the effects of mixtures. This report summarizes the discussions of the work groups and details the recommendations for additional research. PMID:8880000

    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.

  7. Risk Factors in Heating, Ventilating, and Air-Conditioning Systemsfor Occupant Symptoms in U.S. Office Buildings: the EPA BASE Study

    SciTech Connect

    Mendell, M.J.; Lei-Gomez, Q.; Mirer, A.; Seppanen, O.; Brunner, G.

    2006-10-01

    Nonspecific building-related symptoms among occupants of modern office buildings worldwide are common and may be associated with important reductions in work performance, but their etiology remains uncertain. Characteristics of heating, ventilating, and air-conditioning (HVAC) systems in office buildings that increase risk of indoor contaminants or reduce effectiveness of ventilation may cause adverse exposures and subsequent increase in these symptoms among occupants. We analyzed data collected by the U.S. EPA from a representative sample of 100 large U.S. office buildings--the Building Assessment and Survey Evaluation (BASE) study--using multivariate logistic regression models with generalized estimating equations adjusted for potential personal and building confounders. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between seven building-related symptom outcomes and selected HVAC system characteristics. Among factors of HVAC design or configuration: Outdoor air intakes less than 60 m above the ground were associated with approximately doubled odds of most symptoms assessed. Sealed (non-operable) windows were associated with increases in skin and eye symptoms (ORs= 1.9, 1.3, respectively). Outdoor air intake without an intake fan was associated with an increase in eye symptoms (OR=1.7). Local cooling coils were associated with increased headache (OR=1.5). Among factors of HVAC condition, maintenance, or operation: the presence of humidification systems in good condition was associated with an increase in headache (OR=1.4), whereas the presence of humidification systems in poor condition was associated with increases in fatigue/difficulty concentrating, as well as upper respiratory symptoms (ORs=1.8, 1.5). No regularly scheduled inspections for HVAC components was associated with increased eye symptoms, cough and upper respiratory symptoms (ORs=2.2, 1.6, 1.5). Less frequent cleaning of cooling coils or drip pans was associated

  11. Defining the scope of lender liability after Kelley v. EPA: Who will have safe harbor?

    SciTech Connect

    1995-08-01

    In 1980, Congress enacted CERCLA in order to clean up toxic waste sites and identify broad classes of people who would be financially responsible for the clean-up efforts. One of these broad classes of responsible parties includes owners or operators of hazardous waste sites. This category created enormous potential for liability risk for lenders who hold title to contaminated property as collateral. Congress created a {open_quotes}safe harbor{close_quotes} exemption from liability within the definition of owners and operators in order to protect lenders who held title merely as protection of a security interest. Conflicting interpretations have caused a great deal of confusion for lending institutions. In response to fears of unlimited liability expressed by lending institutions and in consideration of the federal government`s increasing role as a secured creditor, the Environmental Protection Agency (EPA) issued a regulation in 1992 that attempted to define clearly the scope of a lender`s liability under CERCLA. This rule provided the lending community with a precise standard by which to guide their actions in order to avoid incurring liability. In Kelley v. EPA, the EPA`s regulation that attempted to clarify issues of lender liability under CERCLA was struck down by the United States Court of Appeals for the D.C. Circuit. The court held that Congress had not granted the EPA authority to promulgate regulations that would define the scope of lender liability in private party litigation. It further determined that federal courts should evaluate claims in private cost recovery actions independent of the EPA`s {open_quotes}institutional view{close_quotes}. This note postulates that the Kelley decision to invalidate the rule once again exposes lenders to unlimited liability under CERCLA by leaving them to make decisions based on an ambiguous statutory provision that has been interpreted both broadly and narrowly in the past.

  12. The Occurrence of 16 EPA PAHs in Food – A Review

    PubMed Central

    Zelinkova, Zuzana; Wenzl, Thomas

    2015-01-01

    Occurrence and toxicity of polycyclic aromatic hydrocarbons (PAHs) have been extensively studied in countries all over the world. PAHs generally occur in complex mixtures which may consist of hundreds of compounds. The U.S. Environmental Protection Agency (EPA) proposed in the 1970 to monitor a set of 16 PAHs which are frequently found in environmental samples. This article reviews the suitability of the 16 EPA PAHs for the assessment of potential health threats to humans stemming from the exposure to PAHs by food ingestion. It presents details on analysis methods, the occurrence of PAHs in food, regulatory aspects, and related risk management approaches. In addition, consideration is given to newer evaluations of the toxicity of PAHs and the requirements for risk assessment and management stemming from them. PMID:26681897

  2. Coordinating activities between NOAA and other agencies.

    PubMed

    Fritz, A T; Buchman, M F

    1997-11-01

    The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) mandate protection of public health, welfare, and the environment at Superfund hazardous waste sites. The NCP requires lead response agenciesto integrate baseline risk assessments into the remedial process that "assess threats to the environment." EPA policy statements direct regional offices to perform thorough, consistent ecological risk assessments, and stress the importance of coordination and technical consultation with the natural resource trustees. As a Federal natural trustee, the National Oceanic and Atmospheric Administration's (NOAA) role and responsibilities within the CERCLA process also are defined and mandated by Federal law. NOAA is responsible for identifying sites in the coastal zone that may affect natural resources, evaluating injury to trust resources, and providing technical advice on assessments and remedial and restoration alternatives. Statutes require lead cleanup agencies and trustee agencies to notify and coordinate with each other during CERCLA response. Over the past ten years, NOAA has gained valuable experience and technical expertise in environmental assessments and in evaluating contaminated aquatic environments. NOAA fulfills its responsibilities through an effective network of Coastal Resource Coordinators (CRCs) who can rapidly respond to local technical requirements and priorities, and coordinate effectively with technical and trustee representatives. In addition to CRCs, an interdisciplinary support group provides technical expertise in the scientific disciplines required to respond to the needs of regional activities. NOAA provides CRCs to coastal EPA regional offices for technical support, and to act as liaisons with Federal and state natural resource trustee agencies.

  5. Risk assessment and risk management at the Canadian Food Inspection Agency (CFIA): a perspective on the monitoring of foods for chemical residues.

    PubMed

    Bietlot, Henri P; Kolakowski, Beata

    2012-08-01

    The Canadian Food Inspection Agency (CFIA) uses 'Ranked Risk Assessment' (RRA) to prioritize chemical hazards for inclusion in monitoring programmes or method development projects based on their relative risk. The relative risk is calculated for a chemical by scoring toxicity and exposure in the 'risk model scoring system' of the Risk Priority Compound List (RPCL). The relative ranking and the risk management options are maintained and updated in the RPCL. The ranking may be refined by the data generated by the sampling and testing programs. The two principal sampling and testing programmes are the National Chemical Residue Monitoring Program (NCRMP) and the Food Safety Action Plan (FSAP). The NCRMP sampling plans focus on the analysis of federally registered products (dairy, eggs, honey, meat and poultry, fresh and processed fruit and vegetable commodities, and maple syrup) for residues of veterinary drugs, pesticides, environmental contaminants, mycotoxins, and metals. The NCRMP is complemented by the Food Safety Action Plan (FSAP) targeted surveys. These surveys focus on emerging chemical hazards associated with specific foods or geographical regions for which applicable maximum residue limits (MRLs) are not set. The data from the NCRMP and FSAP also influence the risk management (follow-up) options. Follow-up actions vary according to the magnitude of the health risk, all with the objective of preventing any repeat occurrence to minimize consumer exposure to a product representing a potential risk to human health.

  6. 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.

  7. EPA Remote Sensing Information Gateway

    NASA Astrophysics Data System (ADS)

    Paulsen, H. K.; Szykman, J. J.; Plessel, T.; Freeman, M.; Dimmick, F.

    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. This is much faster than the usual method of transferring large files via FTP and greatly reduces network traffic. The RSIG applet then visualizes the transferred data on a latitude-longitude map, automatically locating the data in the correct

  5. Electrostatic Plasma Accelerator (EPA)

    NASA Technical Reports Server (NTRS)

    Brophy, John R.; Aston, Graeme

    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.

  6. Study of Risk Assessment Programs at Federal Agencies and Commercial Industry Related to the Conduct or Regulation of High Hazard Operations

    SciTech Connect

    Bari, R.; Rosenbloom, S.; O'Brien, J.

    2011-03-13

    In the Department of Energy (DOE) Implementation Plan (IP) for Defense Nuclear Facilities Safety Board's Recommendation 2009-1, the DOE committed to studying the use of quantitative risk assessment methodologies at government agencies and industry. This study consisted of document reviews and interviews of senior management and risk assessment staff at six organizations. Data were collected and analyzed on risk assessment applications, risk assessment tools, and controls and infrastructure supporting the correct usage of risk assessment and risk management tools. The study found that the agencies were in different degrees of maturity in the use of risk assessment to support the analysis of high hazard operations and to support decisions related to these operations. Agencies did not share a simple, 'one size fits all' approach to tools, controls, and infrastructure needs. The agencies recognized that flexibility was warranted to allow use of risk assessment tools in a manner that is commensurate with the complexity of the application. The study also found that, even with the lack of some data, agencies application of the risk analysis structured approach could provide useful insights such as potential system vulnerabilities. This study, in combination with a companion study of risk assessment programs in the DOE Offices involved in high hazard operations, is being used to determine the nature and type of controls and infrastructure needed to support risk assessments at the DOE.

    RESRAD-CHEM is a computer code developed at Argonne National Laboratory for the U.S. Department of Energy to evaluate chemically contaminated sites. The code is designed to predict human health risks from multipathway exposure to hazardous chemicals and to derive cleanup criteria for chemically contaminated soils. The method used in RESRAD-CHEM is based on the pathway analysis method in the RESRAD code and follows the U.S. Environmental Protection Agency`s (EPA`s) guidance on chemical risk assessment. RESRAD-CHEM can be used to evaluate a chemically contaminated site and, in conjunction with the use of the RESRAD code, a mixed waste site.

  13. 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.

    A significant challenge in toxicology is the 'too many chemicals' problem. Human beings and environmental species are exposed to tens of thousands of chemicals, only a small percentage of which have been tested thoroughly using standard in vivo test methods. This study reviews several approaches that are being developed to deal with this problem by the U.S. Environmental Protection Agency, under the umbrella of the ToxCast programme (http://epa.gov/ncct/toxcast/). The overall approach is broken into seven tasks: (i) identifying biological pathways that, when perturbed, can lead to toxicity; (ii) developing high-throughput in vitro assays to test chemical perturbations of these pathways; (iii) identifying the universe of chemicals with likely human or ecological exposure; (iv) testing as many of these chemicals as possible in the relevant in vitro assays; (v) developing hazard models that take the results of these tests and identify chemicals as being potential toxicants; (vi) generating toxicokinetics data on these chemicals to predict the doses at which these hazard pathways would be activated; and (vii) developing exposure models to identify chemicals for which these hazardous dose levels could be achieved. This overall strategy is described and briefly illustrated with recent examples from the ToxCast programme. PMID:24684691

  20. Genetically at-risk status and individual agency. A qualitative study on asymptomatic women living with genetic risk of breast/ovarian cancer.

    PubMed

    Caiata-Zufferey, Maria

    2015-05-01

    For the last 20 years, genetic tests have allowed unaffected women to determine whether they are predisposed to developing breast/ovarian cancer due to BRCA1/2 gene mutations. In the event of adverse results, women receive a specific label associated with a set of medical recommendations: the genetically at-risk status. This qualitative study adopted a life-course perspective to understand the impact of this status on women's agency. Following a grounded theory design, retrospective biographical interviews were conducted in Switzerland between 2011 and 2013 with 32 unaffected women at risk of developing genetic breast/ovarian cancer and aware of their predisposition for at least three years. The results show that the genetically at-risk status conveys an invitation to transform health into a project, i.e., into a set of planned activities realized in collaboration with the medical system in order to reduce the risk of developing cancer. This health project shapes women's agency in three ways: it enhances, constrains and questions it, thus creating a sense of disorientation about what is considered rational and appropriate in terms of genetic risk management. Based on these findings, the paper concludes by stressing the paradoxes of the genetically at-risk status and the limits of the medical system in managing women designated with it. The paper also suggests that because of the disorientation intrinsic to their situation, genetically at-risk women have to reflexively construct their own health project from a range of available options in ways that are coherent and viable for themselves and their significant others. This process of reflexive construction may be called legitimation. PMID:25813728

    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
