    1992-12-31

    The Environmental Protection Agency (EPA) has assessed the potential lung-cancer risk to the general population due to radon based on the Agency`s general principles of risk assessment. This same approach has been used to assess the impact on public health of other carcinogenic environmental pollutants. This paper briefly describes the application of EPA`s approach to radon and includes a description of the method used by the Agency to estimate that approximately 22,000 lung-cancer deaths per year may be related to radon exposure. Also presented are the weight of evidence for classifying radon as a known human carcinogen and the uncertainties associated with estimating risks from radon exposure. These combined factors reflect the extent of the underlying support and the context for EPA`s estimates of lung-cancer deaths.

    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.

    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. The impact of EPA`s Dioxin Reassessment on waste-to-energy risk assessments

    1997-12-31

    Since the mid-1980s, the US Environmental Protection Agency (EPA) has been attempting to develop a comprehensive mathematical model to be used for regulatory risk assessment. One expression of this model was published by EPA in a 1994 draft Dioxin Reassessment document. The Dioxin Reassessment includes algorithms for performing site-specific risk assessments of combustion sources that differ from those considered to be state-of-the-art in the late 1980s. This paper presents the results of a study that was performed to investigate the impact of EPA`s Dioxin Reassessment on potential human health risks associated with a modern waste-to-energy (WTE) facility. The study evaluated risks associated with a WTE facility equipped with modern air pollution controls using EPA`s methods published in the Dioxin Reassessment and using methods that prevailed prior to the Reassessment`s publication. Although the facility complies with the maximum achievable control technology (MACT) rule for municipal solid waste combustors, the analysis showed that the methodologies presented in the 1994 Dioxin Reassessment produce risks that are up to several orders of magnitude higher than those predicted using earlier state-of-the-art techniques. The most significant risk factors were found to be: (1) the method used to predict wet deposition fluxes including the location of the wet deposition maximum impact point; (2) the surface water model construction and parameterization, and (3) the requirement to include pathways not currently present but rather only based on future land use.

  6. Asbestos worker protection. Environmental Protection Agency (EPA). Final rule.

    PubMed

    2000-11-15

    In this Final Rule, EPA is amending both the Asbestos Worker Protection Rule (WPR) and the Asbestos-in-Schools Rule. The WPR amendment protects State and local government employees from the health risks of exposure to asbestos to the same extent as private sector workers by adopting for these employees the Asbestos Standards of the Occupational Safety and Health Administration (OSHA). The WPR's coverage is extended to State and local government employees who are performing construction work, custodial work, and automotive brake and clutch repair work. This final rule cross-references the OSHA Asbestos Standards for Construction and for General Industry, so that future amendments to these OSHA standards are directly and equally effective for employees covered by the WPR. EPA also amends the Asbestos-in-Schools Rule to provide coverage under the WPR for employees of public local education agencies who perform operations, maintenance, and repair activities. EPA is issuing this final rule under section 6 of the Toxic Substances Control Act (TSCA).

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

    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.

  9. 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.

  10. EPA`s Risk Management Program: Strategies to comply at DOD facilities

    SciTech Connect

    Narayanan, R.

    1997-12-31

    Requirements related to the prevention of accidental chemical releases were first introduced under section 112(r) of the Clean Air Act Amendments of 1990 (CAAA`90). As a result of the CAA requirements, the Environmental Protection Agency (EPA) promulgated the Risk Management Program rule in June of 1996. The rule affects facilities that handle greater than threshold quantity of any regulated substance. The EPA`s list of regulated substances include, but are not limited to, chlorine, propane, ammonia, acrolein, and butane along with a host of other chemicals. Activities at DOD and certain federal facilities that could be subject to the Risk Management Program are ammonia refrigeration units, water and waste water treatment facilities (that use chlorine) and propane storage. If affected, each of these activities will be required to identify and analyze worst-case scenarios and evaluate their impacts offsite. Further, some facilities will also be required to implement a full accident prevention program and an emergency response program. DOD facilities will need to prepare now to meet the risk management program rule requirements. This paper discusses processes typically found at DOD facilities and presents strategies to meet complex program requirements. In addition, potential steps involved in the analyses of release scenarios are illustrated using an hypothetical example

    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.

  18. Science, policy, and trends of metals risk assessment at EPA: how understanding metals bioavailability has changed metals risk assessment at US EPA.

    PubMed

    Reiley, Mary C

    2007-08-30

    The US Environmental Protection Agency (EPA) and the Office of Water have made significant changes in the approaches taken to assessing metals in the aquatic environment. Over the last 20 years, the Office of Water has progressed through a variety of metals assessment tools from total recoverable metal to the biotic ligand model. These changes were initially driven by the recognition that the total metals criteria were out of date and that emerging science would make it possible to address bioavailability more thoroughly. More recent drivers are expectations that the agency ensure the criteria are protective of endangered species and that the agency can bring the best available science to conducting total maximum daily loads (TMDLs) for waters not meeting uses because of metal contamination. Changes have included: moving from total recoverable metals concentration to dissolved metals and the development of dissolved metal to total metal translator guidance, the development of water effect ratios (WERs) guidance, and most recently incorporation of the biotic ligand model (BLM) into criteria derivation for aquatic life protection (USEPA, 2007a. Aquatic Life Ambient Freshwater Quality Criteria-Copper 2007 Revision. EPA-822-R-07-001. http://www.epa.gov/waterscience/criteria/copper/index.htm.). On March 8, 2007, the agency published its Framework for Metals Risk Assessment (USEPA, 2007b. Framework for Metals Risk Assessment. EPA 120/R-07/001. http://www.epa.gov/osa/metalsframework.) discussing the state of the science for the persistent bioaccumulative, and toxic nature of metals and the considerations of this science that will impact many programs. This paper provides a brief insight to these agency activities.

    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)

    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.

    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

    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.

  20. EPA (Environmental Protection Agency) initiates wetlands research in the Pacific Northwest

    Kentula, M.E.

    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.

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

    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.

    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.

  6. 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.

  7. Analysis of 70 Environmental Protection Agency priority pharmaceuticals in water by EPA Method 1694.

    Ferrer, Imma; Zweigenbaum, Jerry A; Thurman, E Michael

    2010-09-01

    The U.S. Environmental Protection Agency (EPA) Method 1694 for the determination of pharmaceuticals in water recently brought a new challenge for treatment utilities, where pharmaceuticals have been reported in the drinking water of 41-million Americans. This proposed methodology, designed to address this important issue, consists of solid-phase extraction (SPE) followed by liquid chromatography-mass spectrometry (LC/MS-MS) using triple quadrupole. Under the guidelines of Method 1694, a multi-residue method was developed, validated, and applied to wastewater, surface water and drinking water samples for the analysis of 70 pharmaceuticals. Four distinct chromatographic gradients and LC conditions were used according to the polarity and extraction of the different pharmaceuticals. Positive and negative ion electrospray were used with two MRM transitions (a quantifier and a qualifier ion for each compound), which adds extra confirmation not included in the original Method 1694. Finally, we verify, for the first time, EPA Method 1694 on water samples collected in several locations in Colorado, where positive identifications for several pharmaceuticals were found. This study is a valuable indicator of the potential of LC/MS-MS for routine quantitative multi-residue analysis of pharmaceuticals in drinking water and wastewater samples and will make monitoring studies much easier to develop for water utilities across the US, who are currently seeking guidance on analytical methods for pharmaceuticals in their water supplies.

    The Environmental Protection Agency (EPA) program to develop proposed generally applicable environmental standards for land disposal of low-level radioactive waste (LLW) and certain naturally occurring and accelerator-produced radioactive wastes has been completed. The elements of the proposed standards for LLW under 40CFR193 of the Code of Federal Regulations include the following: 1. exposure limits for predisposal management and storage operations; 2. criteria for other regulatory agencies to follow in specifying wastes that are below regulatory concern (BRC); 3. postdisposal exposure limits; 4. groundwater protection requirements; and 5. qualitative implementation requirements. This paper focuses on the development of EPA's BRC criteria applicable to the disposal of LLW.

  9. United States Government Accountability Office report on nanotechnology: nanomaterials are widely used in commerce, but EPA faces challenges in regulating risk.

    2010-01-01

    Nanotechnology involves the ability to control matter at the scale of a nanometer--one billionth of a meter. The world market for products that contain nanomaterials is expected to reach $2.6 trillion by 2015. In this context, the United States Government Accountability Office (GAO): (1) identified examples of current and potential uses of nanomaterials, (2) determined what is known about the potential human health and environmental risks from nanomaterials, (3) assessed actions the Environmental Protection Agency (EPA) has taken to better understand and regulate the risks posed by nanomaterials as well as its authorities to do so, and (4) identified approaches that other selected national authorities and U.S. states have taken to address the potential risks associated with nanomaterials. The GAO analyzed selected laws and regulations, reviewed information on the EPA's Nanoscale Materials Stewardship Program, and consulted with EPA officials and legal experts to obtain their perspectives on the EPA's authorities to regulate nanomaterials.

    EPA will issue an RFP to initiate the SITE-005 solicitation for demonstration of technologies under the Superfund Innovative Technology Evaluation (SITE) Program. This portion of the SITE program offers a mechanism for conducting a joint technology demonstration between EPA and the private sector. The goal of the demonstration program is to provide an opportunity for developers to demonstrate the performance of their technologies on actual hazardous wastes at Superfund sites, and to provide accurate and reliable data on that performance. Technologies selected must be of commercial scale and provide solutions to problems encountered at Superfund Sites. Primary emphasis in the RFP is on technologies that address: treatment of mixed, low level radioactive wastes in soils and groundwater; treatment of soils and sludges contaminated with organics and/or inorganics, materials handling as a preliminary step to treatment or further processing, treatment trains designed to handle specific wastes, are in situ technologies, especially those processes providing alternatives to conventional groundwater pump and treat techniques.

    The purpose of this report is two-fold. First, the risk assessment methodology for both RESRAD and the EPA’s tools is reviewed. 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.

  15. Perspective on the use of LNT for radiation protection and risk assessment by the U.S. Environmental Protection Agency.

    PubMed

    Puskin, Jerome S

    2009-08-21

    The U.S. Environmental Protection Agency (EPA) bases its risk assessments, regulatory limits, and nonregulatory guidelines for population exposures to low level ionizing radiation on the linear no-threshold (LNT) hypothesis, which assumes that the risk of cancer due to a low dose exposure is proportional to dose, with no threshold. The use of LNT for radiation protection purposes has been repeatedly endorsed by authoritative scientific advisory bodies, including the National Academy of Sciences' BEIR Committees, whose recommendations form a primary basis of EPA's risk assessment methodology. Although recent radiobiological findings indicate novel damage and repair processes at low doses, LNT is supported by data from both epidemiology and radiobiology. Given the current state of the science, the consensus positions of key scientific and governmental bodies, as well as the conservatism and calculational convenience of the LNT assumption, it is unlikely that EPA will modify this approach in the near future.

    1988-09-01

    Region 10, U.S. EPA, has conducted chemical and biological monitoring during low-flow conditions from 1972 to 1986 along the South Fork Coeur d'Alene River in northern Idaho, a stream with a long history of severe metals pollution from mining activities. During 1986, metals analysis of sediments and tissues from the lower Coeur d'Alene River and Coeur d'Alene Lake was also conducted. Due chiefly to effluent controls at the Bunker Hill Complex Superfund site, concentrations of zinc, cadmium, and lead were reduced since the 1970's. Although levels of zinc and cadmium remain well above national criteria for protection of cold water biota, recovery of aquatic life has been substantial, with the lower mainstream now supporting a successful sports fishery. Sediments in the lower Coeur d'Alene system remain heavily contaminated with toxic metals, although high levels in edible fish tissues were not found. Allowable permit limits (as of 1986) for metals (primarily cadmium) have the potential of increasing in-stream metals concentrations. Water quality-based permits are particularly important for aquatic life protection of the South Fork upstream of Mullan and the mainstream downstream of the S.F. confluence.

  6. 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.

    2008-11-15

    The toxicity value database of the United States Environmental Protection Agency's (EPA) National Homeland Security Research Center has been in development since 2004. The toxicity value database includes a compilation of agent property, toxicity, dose-response, and health effects data for 96 agents: 84 chemical and radiological agents and 12 biotoxins. The database is populated with multiple toxicity benchmark values and agent property information from secondary sources, with web links to the secondary sources, where available. A selected set of primary literature citations and associated dose-response data are also included. The toxicity value database offers a powerful means to quickly and efficiently gather pertinent toxicity and dose-response data for a number of agents that are of concern to the nation's security. This database, in conjunction with other tools, will play an important role in understanding human health risks, and will provide a means for risk assessors and managers to make quick and informed decisions on the potential health risks and determine appropriate responses (e.g., cleanup) to agent release. A final, stand alone MS ACESSS working version of the toxicity value database was completed in November, 2007.

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

    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.

    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.

    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.

  18. U.S. Environmental Protection Agency radiogenic risk projections: uncertainty analysis.

    PubMed

    Pawel, David J

    2013-01-01

    The U.S. Environmental Protection Agency (EPA) has updated its estimates of cancer risks due to low doses of ionizing radiation for the U.S. population, as well as their scientific basis. For the most part, these estimates were calculated using models recommended in the recent National Academy of Sciences' (BEIR VII) report on health effects from low levels of ionizing radiation. The new risk assessment includes uncertainty bounds associated with the projections for gender and cancer site-specific lifetime attributable risks. For most cancer sites, these uncertainty bounds were calculated using probability distributions for BEIR VII model parameter values, derived from a novel Bayesian analysis of cancer incidence data from the atomic bomb survivor lifespan study (LSS) cohort and subjective distributions for other relevant sources of uncertainty. This approach allowed for quantification of uncertainties associated with: 1) the effect of sampling variability on inferences drawn from the LSS cohort about the linear dose response and its dependence on temporal factors such as age-at-exposure, 2) differences in the radiogenic risks in the Japanese LSS cohort versus the U.S. population, 3) dosimetry errors, and 4) several other non-sampling sources. Some of the uncertainty associated with how risk depends on dose and dose rate was also quantified. For uniform whole-body exposures of low-dose gamma radiation to the entire population, EPA's cancer incidence risk coefficients and corresponding 90% uncertainty intervals (Gy) are 9.55 × 10 (4.3 × 10 to 1.8 × 10) for males and 1.35 × 10 (6.5 × 10 to 2.5 × 10) for females, where the numbers in parentheses represent an estimated 90% uncertainty interval. For many individual cancer sites, risk coefficients differ from corresponding uncertainty bounds by factors of about three to five, although uncertainties are larger for cancers of the stomach, prostate, liver, and uterus. Uncertainty intervals for many, but not all

    An easy-to-use indoor-air-quality (IAQ) model is described. It is multi-compartmented and based on a well-mixed mixing model. Sources and sinks are allowed in each compartment. A menu-driven fill-in-the-form user interface controls program flow and is used to obtain data from the user. On-screen graphical output is provided. The model estimates the effects of heating, ventilation, and air conditioning (HVAC), air cleaning, room-to-room air movement, and natural ventilation on pollutant concentrations. Experiments conducted in the EPA test house using moth crystal cakes for model verification are described. The agreement between small chamber emission factors, model predictions, and test house data is very good. Predicted weight loss of the moth crystal cakes was within 5% of the measured weight loss. Predicted room concentrations of p-dichlorobenzene are within 20% of the measured values. Future directions for model development and experimental studies are discussed.

    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.

  9. US EPA (Environmental Protection Agency) perspective on AOC (assimilable organic carbon) research as related to coliform colonization and compliance problems

    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.

    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.

  17. Bottom-Up Risk Regulation? How Nanotechnology Risk Knowledge Gaps Challenge Federal and State Environmental Agencies

    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.

  20. Dietary reference intakes for DHA and EPA.

    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.

    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.

  2. Summary of the EPA (Environmental Protection Agency) workshop on carcinogenesis bioassay via the dermal route. Final technical report

    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.

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

    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.

    1992-08-01

    The United States Environmental Protection Agency (EPA) is developing national regulations to control for disinfectants and disinfection by-products (D/DBPs) in public drinking water supplies. EPA intends to propose regulations that will apply to all public water systems using disinfection and serving non-transient populations -- approximately 220 million people. This regulation would be unlike the current maximum contaminant level (MCL) for total trihalomethanes (TTHMs) which only pertains to systems serving more than 10,000 people. A fundamental goal in setting any new regulation is to be able to conclude with confidence that the resultant changes in treatment would lead to a significant overall decrease in risk to public health. This paper will describe the analysis that EPA is undertaking in pursuit of meeting this goal.

    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

    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

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

    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

    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.

    The U.S. Environmental Protection Agency (EPA) began a "reassessment" of the risks posed by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD or dioxin) and related chemicals in 1991 and issued an interim report in 1994. In 1995, the Science Advisory Board (SAB) reviewed this document and requested revisions. After considerable additional work, EPA issued its final draft report in September 2000. A new EPA SAB reviewed this draft and issued its recommendations in June 2001. This group of scientists offered suggestions to EPA on the following topics, which are discussed in some detail in this article: classification as a "known" human carcinogen, how to estimate the carcinogenic potency, the possible significance of the noncancer hazard, the proper dose metric for cancer and noncancer effects, the uncertainties inherent in the toxicity equivalency factor approach, use of the margin of exposure approach, adequacy of the exposure assessment, body burden calculations, risks to breast feeding children, nonmonotonic responses (U- or J-shaped dose-response curves, or hormetic effect), the possible significance of naturally occurring dioxin-like chemicals, and risks to special populations. The basis for the recommendations, as generally presented in the SAB report, is described here. A discussion of some of the recently published work within the regulatory and scientific communities that has been issued since the SAB report is also presented.

    The evaluation of the POWERFuel Extender System was conducted upon the application of the manufacturer. The device is claimed to improve fuel economy and driveability and to reduce exhaust emissions and required engine maintenance. The device is classified by EPA as a vapor-air bleed device. EPA fully considered all of the information submitted by the applicant. The evaluation of the POWERFuel Extender System was based on that information and on EPA's experience with other similar devices. Although, in theory, the introduction of alcohol and water could have a favorable effect on an engine's cleaniness, power and maintenance requirements and could even allow some vehicles to use lower octane fuel, data were not submitted to substantiate that the POWERFuel Extender System could cause these benefits.

    Abstract Studies have documented cumulative health effects of chemical and nonchemical exposures, particularly chronic environmental and social stressors. Environmental justice groups have advocated for community participation in research that assesses how these interactions contribute to health disparities experienced by low-income and communities of color. In 2009, the U.S. Environmental Protection Agency issued a request for research applications (RFA), “Understanding the Role of Nonchemical Stressors and Developing Analytic Methods for Cumulative Risk Assessments.” Seven research projects were funded to help address this knowledge gap. Each engaged with communities in different ways. We describe the community engagement approaches of the seven research projects, which ranged from outreach through shared leadership/participatory. We then assess the experiences of these programs with respect to the community engagement goals of the RFA. We present insights from these community engagement efforts, including how the grants helped to build or enhance the capacity of community organizations in addition to contributing to the research projects. Our analysis of project proposals, annual grantee reports, and participant observation of these seven projects suggests guidelines for the development of future funding mechanisms and for conducting community-engaged research on cumulative risk involving environmental and social stressors including: 1) providing for flexibility in the mode of community engagement; 2) addressing conflict between research timing and engagement needs, 3) developing approaches for communicating about the uniquely sensitive issues of nonchemical stressors and social risks; and 4) encouraging the evaluation of community engagement efforts.

  19. Strategy for environmental health research at EPA

    Reiter, L.W.; Sexton, K.

    1990-12-01

    Major environmental legislation has given the U.S. Environmental Protection Agency (EPA) the regulatory tools it needs to protect our environment and public health. Environmental protection, however, requires more than legislative vehicles; appropriate regulatory decisions based on those laws must be founded on scientific data concerning the scope and magnitude of health risks associated with the environmental hazards to which the public is exposed. To address the broad range of environmental contaminants covered under various legislative statutes, HERL research must assist EPA in evaluating the health risks for diverse environmental agents. While the chemical and physical composition of these pollutants differs significantly, the evaluation of their health effects must address a common set of issues: exposure, or the extent to which humans are exposed to pollutants in the environment; dose, or the relationship between the exposure and the dose of the pollutant received at the site(s) of toxic action within the body; and effect, or the health impact from the pollutant dose. These fundamental issues form the risk assessment paradigm that underlies the research needs of all EPA regulatory program areas, and therefore they are central to the entire HERL program.

    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.

    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.

  19. Food, risk and place: agency and negotiations of young people with food allergy.

    PubMed

    Stjerna, Marie-Louise

    2015-02-01

    Potentially life-threatening food allergies are increasing among children in the Western world. Informed by childhood studies, this article explores young people's management of food allergy risk and highlights their agency in relation to food, eating and place. Drawing on individual interviews with 10 young people who took part in a larger multi-method study of young people's experiences of food allergies, the findings demonstrate that the management of health risks means, to some extent, trying to control the uncontrollable. A reaction can occur at any time and to experience a severe reaction entails a temporarily loss of control. The strategies the young people develop to avoid allergic reactions can be understood both as responses to this uncertainty and as manifestations of their agency. Their risk experiences vary with place; at school and in other public places they face social as well as health risks. What we see is not agency as a voluntary choice but that young people with food allergies experience tensions between their own competence to manage different types of risks and their dependence on others to adjust to their needs. Thus, the relational aspects of young people's agency come to the fore.

  20. Congress moves to set priorities for EPA research spending

    SciTech Connect

    Hanson, D.

    1993-05-31

    Research and development spending at the Environmental Protection Agency is slated to rise more than 5% in President Bill Clinton's fiscal 1994 budget. Congress is stepping in, however, and may have something to say not only about how much money is spent, but also how it is spent. For the first time in a decade, formal authorization of EPA's Office of Research and Development (ORD) is moving through Congress. The ORD authorization was approved May 20 in the House Science Committee's Subcommittee on Technology, Environment and Aviation. Introduced by subcommittee chairman Rep. Tim Valentine (D.-N.C.), the authorization bill (H.R. 1994) would provide $475 million in funding for fiscal 1994. This equals the amount proposed by Clinton, $536 million, if about $60 million earmarked for Superfund-related research is removed. The Valentine bill would set out programmatic guidelines for EPA research, requiring fundamental research in ecology, health, and risk reduction. It would also require the agency's Science Advisory Board to review these programs and submit progress reports to Congress every two years. Another part of the bill would require EPA to consolidate agency efforts to identify, compare, and assess risk to public health and the environment posed by pollution.

    SciTech Connect

    Hautman, N.

    1988-01-01

    This report attempts to determine the extent of nonpoint source pollution in Region V. The report analyzes and summarizes the nonpoint source and clean lakes reports required under the Clean Water Act amendments of 1987. The reports share common elements such as a focus on agricultural sources and the use of hard data as well as professional judgment. However, they differ in overall design, definitions of key elements, level of analysis, thoroughness, and effectiveness. The summary considers the reports from two aspects: structure and the extent to which they comply with Sec. 319 and U.S. EPA reports as they are constructed. Information in the 305 (b) reports adds to the scope of each state's nonpoint source program and is referred to here. Following the summary is a discussion, accompanied by appropriate tables, of the nonpoint source pollution extent.

    NASA Astrophysics Data System (ADS)

    Showstack, Randy

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

  17. Falls risk assessment begins with hello: lessons learned from the use of one home health agency's fall risk tool.

    PubMed

    Flemming, Patricia J; Ramsay, Katherine

    2012-10-01

    Identifying older adults at risk for falls is a challenge all home healthcare agencies (HHAs) face. The process of assessing for falls risk begins with the initial home visit. One HHA affiliated with an academic medical center describes its experience in development and use of a Falls Risk Assessment (FRA) tool over a 10-year period. The FRA tool has been modified since initial development to clarify elements of the tool based on research and to reflect changes in the Outcome and Assessment Information Set (OASIS) document. The primary purpose of this article is to share a validated falls risk assessment tool to facilitate identification of fall-related risk factors in the homebound population. A secondary purpose is to share lessons learned by the HHA during the 10 years using the FRA.

  5. 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.

  12. 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

    Warner, B.J.; Cheng, S.C.; Friedman, C.S.; Mitrosky, S.; Snyder, A.D.

    1984-03-01

    The experimental design and the results of an interlaboratory study of U.S. Environmental Protection Agency (USEPA) method 501.1 to detect trihalomethanes in drinking water are described herein. In the method, trihalomethanes are extracted by an inert gas which is bubbled through the aqueous sample. The vapors are then trapped on a short column containing a suitable sorbent. The trapped compounds are subsequently thermally desorbed onto the head of a gas chromatographic column. An electrolytic conductivity detector is used to measure the compounds. The six concentrations of spiking solutions contained chloroform, bromodichloromethane, chlorodibromomethane and bromoform. The two waters used in the study were distilled and drinking water, both supplied by the individual laboratories. Statistical analyses and conclusions in this report are based on analytical data obtained by twenty collaborating laboratories. This report was submitted in partial fulfillment of contract 68-03-2856 by Monsanto Research Corporation under the sponsorship of the U.S. Environmental Protection Agency. The report covers a period from September 1979 to December 1982.

  15. Cyanotoxins in inland lakes of the United States: Occurrence and potential recreational health risks in the EPA National Lakes Assessment 2007

    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.

    PubMed

    Ragsdale, Kathleen; Anders, Jessica T; Philippakos, Effie

    2007-01-01

    Sexual risk variability among brothel-based sex workers has been shown to be influenced by fear of HIV transmission, and by culture-bound gender norms as well as economic need, yet the effect of sexual agency on impoverished Latina sex workers' risk behavior with their clients remains poorly characterized. We investigated perceived health beliefs regarding susceptibility to/severity of HIV/AIDS, and sexual agency regarding barriers to condom use, benefits of unprotected sex, and risk-reduction behavior with clients among a sample of 33 brothel workers in Belize. Although 77% of participants felt at risk for HIV, only 30% always use condoms and 43% did not refuse unprotected sex with clients. Participants' narrative explanations for unprotected sex emphasized that clients'preferences often overrode brothel workers fear of HIV, and that the health benefits of using condoms with clients were often weighed against the social benefits of unprotected sex. Implications for brothel-based condom promotion programs and further research are discussed.

  5. A critical review of the U.S. EPA's risk assessment for the land application of sewage sludge.

    PubMed

    Mathney, Jennifer M J

    2011-01-01

    Sewage sludge is a complex mixture of inorganic and organic materials and pathogens generated by the treatment of domestic sewage. Section 40 of the Code of Federal Regulations Part 503 regulates the land application of sewage sludge based on pathogen content and sets standards for nine inorganic chemicals. It is believed that the Part 503 standards are protective of human health and the environment and that sewage sludge applied to land poses little risk. A critical inspection of the pertinent literature, however, reveals that the standards were based on outdated methods, outdated data, inaccurate data, and flawed assumptions, leading to underestimation of risk. The standards are not sufficiently protective, and even if changes were made, sewage sludge is so complex that it is very unlikely it could be monitored to ensure the protection of human health and the environment. For these reasons, the practice of land application of sewage sludge must be discontinued. PMID:21411425

  15. Risk communication: Dioxin and municipal waste combustion

    SciTech Connect

    Pirages, S.W.

    1996-12-31

    September 1994, the Environmental Protection Agency (EPA) released its long awaited dioxin reassessment report. The findings expressed in this report have increased public concern about dioxin emissions from municipal waste combustion (MWC). This concern can jeopardize continued implementation of this solid waste management option. To meet today`s environmental challenge, MWC owners/operators must develop an effective communication strategy for addressing public concerns about perceived health and environmental threats associated with dioxin emissions. The focus will depend upon the concerns of specific communities: a public health concern, apprehension about personal risks, or public indignation with corporate activities. Differences in the basis of concern must be addressed if a communication strategy is to have some impact on community actions. Public reactions to the results presented in EPA`s dioxin reassessment report likely will be a concern about personal risks associated with dioxin/furan emissions. A communication strategy should provide information about the several problems associated with EPA`s findings. Criticisms expressed by the scientific community and the EPA Science Advisory Board (SAB) can be presented as evidence that the EPA conclusions lack scientific credibility. Communities need to understand the assumption used by EPA in its exposure assessment and the exaggerated exposure conditions represented by EPA`s findings about dioxin emissions.

  16. FDA-EPA Public Health Guidance on Fish Consumption: A Case Study on Informal Interagency Cooperation in "Shared Regulatory Space".

    PubMed

    Holden, Mark

    2015-01-01

    This article is a case study on how administrative agencies interact with each other in cases of shared regulatory jurisdiction. The theoretical literature on the topic of overlapping jurisdiction both (1) makes predictions about how agencies are expected to behave when they share jurisdiction, and (2) in recent iterations argues that overlapping jurisdiction can confer unique policymaking benefits. Through the lens of that theoretical literature, this article examines the relations between the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) regarding the public health risks posed by mercury in fish. It concludes that the FDA-EPA case study (1) corroborates the extant theoretical accounts of how agencies behave in cases of overlapping jurisdiction, (2) supports the conclusion of the recent scholarship that overlapping jurisdiction can confer unique policy benefits, and (3) reveals a few wrinkles not given adequate treatment in the extant literature.

  18. NASA's Agency-wide Strategy for Environmental Regulatory Risk Analysis and Communication

    Duda, Kristen; Scroggins. Sharon

    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

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

    SciTech Connect

    Macedonia, J.; Vollaro, R.; Culligan, K.; Sheppard, M.

    1997-12-31

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

    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.

    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

  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).

  12. 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.

  13. 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

  14. 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.

  15. 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

  18. 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.

    2014-01-01

    In the European Medicines Agency (EMA), the involvement of patients has been increasingly recognized as valuable and necessary. Specifically in scientific committees, patients through patient representatives are actively involved in deliberations and decision making processes. These scientific committees are meant to ensure that licensed medicines have a positive benefit–risk ratio in favour of the patients and users. To investigate what the contributions are of patient representatives in benefit–risk assessment, we interviewed 15 scientific committee members, 10 of whom are/were EU-state regulatory representatives and five are/were patient representatives. We asked the participants questions related to the benefit–risk assessment tasks of their committees, the connection between patient representatives and the patient perspective, and the contribution of patient representatives in the various benefit–risk assessments tasks. We found that the contribution of patient representatives benefit–risk assessment may be a variable of the benefits and the risks involved in the drug such that the necessity of their contribution is strongly felt when both benefits and risks are high, when benefits are almost equal or are equal to risks and when both benefits and risks are low. In terms of the various benefit–risk tasks, patient representatives contribute to benefit–risk analysis by providing criteria that help define the benefit–risk picture. In benefit–risk evaluation, patient representatives aid in providing a specific basis for the values and weights given to specific benefits and risks and in decision making, they provide what may be a crucial patient perspective in terms of the acceptability of risks. Hence, patient representatives provide a specific expertise in these scientific committees. PMID:24995713

  9. 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.

    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.

  13. Effects of residential mobility on individual versus population risk of radon-related lung cancer

    SciTech Connect

    Warner, K.E.; Courant, P.N.; Mendez, D.

    1995-12-01

    The U.S. Environmental Protection Agency (EPA) does not consider the effects of normal patterns of residential mobility in estimating individual radon-related lung cancer risks. As a consequence, the EPA`s population risk estimates may have little hearing on individual risks, and remediation of high-radon homes may have only small health benefits for the individuals who remediate their homes. Through a simulation analysis, we examine the effects of residential mobility on radon exposure and lung cancer risk. Given normal mobility, only 7% of eventual radon-related mortality among current 30 year olds will occur in the 5% currently living in homes above 4 pCi/l (the EPA`s action level for remediation), in contrast with an estimate of 31% of deaths when mobility is ignored. Above 10 pCi/l, the no-mobility assumption implies 10.3% of deaths, compared to only 0.4% when mobility is taken into account. We conclude that knowledge of one`s current radon exposure is not necessarily a useful guide to one`s risk, especially for residents of the high-radon homes targeted for remediation by the EPA. The risk of such individuals is likely to be substantially lower than that implied in the EPA`S risk charts. If people currently living in high-radon homes remediate their houses, the majority of the resulting health benefits will accrue to future occupants of their homes. 25 refs., 1 fig., 3 tabs.

    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

  16. EPA`s integrated nitrogen oxides strategy

    SciTech Connect

    1997-12-31

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

  19. 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.

    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.

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

    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.

    The U.S. Environmental Protection Agency (EPA) is developing a radiation site cleanup regulation for the protection of the public from radionuclide contamination at sites that are to be cleaned up and released for public use. The regulation will apply to sites under the control of Federal agencies, and to sites licensed by the Nuclear Regulatory Commission (NRC) or NRC Agreement States. The agency is therefore conducting a comprehensive technical analysis aimed at developing information that will be used to support the rule. This presentation describes the regulation and the approach developed to determine how radiological health impacts and volumes of soil requiring remediation vary as functions of the possible cleanup dose or risk level.

  11. A discussion of the U.S. EPA methodology for determining Water Quality Standards (WQS).

    PubMed

    Burmaster, D E; von Stackelberg, K E

    1992-06-01

    Based on material published by the U.S. Environmental Protection Agency (U.S. EPA) in the Federal Register for 19 November 1991, many state environmental agencies have proposed and/or adopted revisions to their State Water Quality Standards (WQS) for organic and inorganic chemicals in fresh and marine waters (see, for example, State of Connecticut, Department of Environmental Protection, Bureau of Water Management, (1992), memorandum to Interested Parties concerning the Water Quality Standards Hearing Report). Generally, many states simply republish the U.S. EPA's proposed Water Quality Criteria (WQC) as the State's proposed WQS. Many of the state WQS and federal WQC values--especially those for organic compounds regulated as human or animal carcinogens--are much more stringent than the values now in effect because the U.S. EPA's new methodology (i) for estimating exposure point concentrations, exposure doses, carcinogenic potency, and incremental lifetime cancer risk and (ii) for setting the target acceptable risk combine a series of conservative assumptions into an equally conservative set of results. In the Federal Register proposal, the U.S. EPA failed to honor its standard risk assessment methodology in that (i) it failed to perform a quantitative or even qualitative uncertainty analysis and (ii) it failed to analyze the overall degree of conservatism in the results. The U.S. EPA suggested that the analysis is suitably conservative for the average exposed adult, but it failed to consider various phenomena that make the proposed WQC far more conservative than acknowledged or intended. To focus on a central problem of manageable size, this article dissects the method by which the U.S. EPA calculates proposed WQC for organic chemicals regulated as human or animal carcinogens. Because the results for most such chemicals are driven by the pathway for the human ingestion of fish which have bioconcentrated the chemicals from the water column (as opposed to the

  15. 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.

    SciTech Connect

    1998-04-01

    Ecological risk assessment evaluates the likelihood that adverse ecological effects may occur or are occurring as a result of exposure to one or more stressors. Ecological risk assessment provides a critical element for environmental decision making by giving risk managers an approach for considering available scientific information along with the other factors they need to consider (e.g., social, legal, political, or economic) in selecting a course of action. The primary audience for this document is risk assessors and risk managers at EPA, although these Guidelines also may be useful to others outside the Agency.

  18. Examining women's agency in managing intimate partner violence and the related risk of homelessness: The role of harm minimisation.

    PubMed

    Meyer, Silke

    2016-01-01

    Intimate partner violence (IPV) has a detrimental impact on women and children's emotional, physical and social well-being and has been identified as one of the most common contributors to women's experiences of housing instabilities and homelessness. Women affected by IPV often experience a great level of uncertainty around housing solutions when trying to leave an abusive partner. This study explores women's responses to IPV and the related risk of homelessness through women's narratives (n = 22) in Queensland, Australia. Of particular interest are women's decisions and actions to minimise the impact of IPV as well as homelessness on their and their children's safety and well-being. Findings reveal that women's agency in relation to harm minimisation can take various forms, including the decision to stay with, leave or return to an abusive partner. The data offer insights into women's strategic attempts to manage IPV and the related risk of homeless while trying to minimise the harm associated with one and the other. Implications for understanding women's agency in managing IPV and the related risk of homelessness and providing adequate support mechanisms to improve women and children's social, emotional and physical well-being are discussed.

    Governments that procure pharmaceutical products from an Essential Medicine List (EML) bear special responsibility for the quality of these products. In this article we examine the possibility of developing a pharmaceutical product quality risk assessment scheme for use by government procurement officials. We use the Chinese EML as a basis, and US recall data is examined as it is publically available.This is justified as the article is only concerned with inherent product quality risks. After establishing a link between Chinese essential medicines and those available in the US, we examine US recall data to separate product specific recalls. We conclude that, in addition to existing manufacturing based risks, there are two other product specific risks that stand out from all others, degradation and dissolution failure. Methodology for relative product risk for degradation is needed to be developed and further work is required to better understand dissolution failures which largely occur with modified-release solid oral products. We conclude that a product specific quality risk profile would be enhanced by including a risk assessment for degradation for all products, and in the case of solid oral products, dissolution.

    Ryan, J.V.; Srivastava, R.K.

    1989-10-01

    This report summarizes the proceedings of an EPA/Institut Francais du Petrole (IFP) cosponsored workshop addressing direct nitrous oxide (N2O) emission from fossil-fuel combustion. The third in a series, it was held at the IFP in Rueil-Malmaison, France, on June 1-2, 1988. Increasing atmospheric N2O concentrations have been linked to depletion of stratospheric ozone (O3) and to global-climate warming. The combustion of fossil fuels has been identified as a potential major anthropogenic source of N2O. The workshop had two goals: (1) to exchange information among various international research and industrial groups that are involved in N2O chemistry, modeling, and measurement; and (2) to develop a network for coordinating future related efforts.

  4. Court date for EPA acid rain rule

    SciTech Connect

    Lobsenz, G.

    1994-03-04

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

The agenda for the last weeks of the Bush Administration includes completing work on proposed rules on reformulated gasoline, accelerated phaseout of ozone-depleting substances, field tests of biotechnology-derived pesticides, and safer alternatives to currently used pesticides. In a mid-November memo, EPA administrator William K. Reilly told his staff, We have 71 days left until the inauguration. Let's use them as vigorously and productively as possible. In focusing the agenda, he says, we should close on those policies and Institutional reforms that are near completion, and take actions required to meet statutory and judicial deadlines and to prepare the agency to respond to challenges it will face all too soon. Those areas include a pending decision by the Supreme Court on whether to hear an appeal of a lower court's ruling against EPA's de minimis interpretation of the Delaney clause barring cancer-causing pesticide residues from processed foods. If the lower court's decision is upheld, EPA will be required to change its residue tolerances. Other targets include a rule on Resource Conservation and Recovery Act corrective action management units and a list of acceptable and unacceptable substitutes for chlorofluorocarbons and halons.

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

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

    SciTech Connect

    Veil, J.

    1995-05-01

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

  17. EPA proposes new rules for injection wells

    NASA Astrophysics Data System (ADS)

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

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

    SciTech Connect

    Lucinda Minton Langworthy

    2006-06-15

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

  5. Electrostatic Plasma Accelerator (EPA)

    NASA Technical Reports Server (NTRS)

    Brophy, John R.; Aston, Graeme

    1995-01-01

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

    1993-07-15

    EPA prepared the report in response to the Congressional mandate in Public Law 102-389 (the Chafee-Lautenberg Amendment to EPA's Appropriation Bill, enacted October 6, 1992) which directs the Administrator of the US Environmental Protection Agency (EPA) to report to Congress on EPA's findings regarding the risks of human exposure to radon, the costs for controlling or mitigating that exposure, and the risks posed by treating water to remove radon. The Chafee-Lautenberg Amendment called for an explicit multimedia comparison of the risks from radon in indoor air and drinking water. Congress placed the requirement on the Agency because of the concern voiced in the United States over the costs to be incurred by public water systems in the control of radon in drinking water while a larger threat from indoor air was not being addressed except through voluntary measures. Amendments to the Safe Drinking Water Act in 1986 called for the regulation of radon in drinking water.

    Lim, Seong-Rin; Lam, Carl W; Schoenung, Julie M

    2011-09-01

    Life Cycle Impact Assessment (LCIA) and Risk Assessment (RA) employ different approaches to evaluate toxic impact potential for their own general applications. LCIA is often used to evaluate toxicity potentials for corporate environmental management and RA is often used to evaluate a risk score for environmental policy in government. This study evaluates the cancer, non-cancer, and ecotoxicity potentials and risk scores of chemicals and industry sectors in the United States on the basis of the LCIA- and RA-based tools developed by U.S. EPA, and compares the priority screening of toxic chemicals and industry sectors identified with each method to examine whether the LCIA- and RA-based results lead to the same prioritization schemes. The Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) is applied as an LCIA-based screening approach with a focus on air and water emissions, and the Risk-Screening Environmental Indicator (RSEI) is applied in equivalent fashion as an RA-based screening approach. The U.S. Toxic Release Inventory is used as the dataset for this analysis, because of its general applicability to a comprehensive list of chemical substances and industry sectors. Overall, the TRACI and RSEI results do not agree with each other in part due to the unavailability of characterization factors and toxic scores for select substances, but primarily because of their different evaluation approaches. Therefore, TRACI and RSEI should be used together both to support a more comprehensive and robust approach to screening of chemicals for environmental management and policy and to highlight substances that are found to be of concern from both perspectives.

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

    SciTech Connect

    Bleiler, J.A.

    1996-09-01

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

  12. Aflatoxin control--how a regulatory agency managed risk from an unavoidable natural toxicant in food and feed.

    PubMed

    Park, D L; Stoloff, L

    1989-04-01

    The control by the Food and Drug Administration (FDA) of aflatoxin, a relatively recently discovered, unavoidable natural contaminant produced by specific molds that invade a number of basic food and feedstuffs, provides an example of the varying forces that affect risk assessment and management by a regulatory Agency. This is the story of how the FDA responded to the initial discovery of a potential carcinogenic hazard to humans in a domestic commodity, to the developing information concerning the nature of the hazard, to the economic and political pressures that are created by the impact of natural forces on regulatory controls, and to the restraints of laws within which the Agency must work. This story covers four periods: the years of discovery and action decisions on the basis of meager knowledge and the fear of cancer; the years of tinkering on paper with the regulatory process, the years of digestion of the accumulating knowledge, and the application of that knowledge to actions forced by natural events; and an audit of the current status of knowledge about the hazard from aflatoxin, and proposals for regulatory control based on that knowledge.

  14. Exposure factors resources: contrasting EPA's Exposure Factors Handbook with international sources.

    PubMed

    Phillips, Linda J; Moya, Jacqueline

    2014-01-01

    Efforts to compile and standardize human exposure factors have resulted in the development of a variety of resources available to the scientific community. For example, the US Environmental Protection Agency (EPA) developed the Exposure Factors Handbook and Child-specific Exposure Factors Handbook to promote consistency among its various exposure-assessment activities. The US EPA handbooks are compilations of human exposure factors data, including anthropometric and sociocultural data (e.g., body weights, skin-surface areas, and life expectancy), behavioral data (e.g., non-dietary ingestion rates, activity/time use patterns, and consumer product use), factors that may be influenced by the physiological needs of the body, metabolic activity, and health and weight status (e.g., water and food intake, and inhalation rates), and other factors (e.g., building characteristics). Other countries have engaged in similar efforts to compile and standardize exposure factors for use in exposure and risk assessments. For example, the ExpoFacts database contains data for 30 European Union countries. Australia, Canada, Japan, Korea, and Taiwan have developed, or are developing, documents that provide exposure factors data relevant to their populations. The purpose of this paper is to provide an overview of some of the available exposure factors resources; to explore some of the similarities and differences between the US EPA Exposure Factors Handbook and selected other international resources, and to highlight data gaps and present some considerations for promoting consistency among these resources.

  18. Congress ends session with a whimper, but EPA is roaring

    SciTech Connect

    Begley, R.

    1994-10-19

    The end of session for Congress (October 1994) marked a disturbing end for environmental concerns which did not see Congressional action. EPA`s agenda of worker protection, chemical monitoring and criminal enforcement will most likely resurface. Legislation that died included Superfund reform, Clean Water Act and Product liability. However, NAFTA got passed, as did a hazardous materials transportation reauthorization and risk assessment in an agricultural bill.

  19. Role of LEPCs in risk management and risk communication

    SciTech Connect

    Mannan, M.

    1995-12-31

    Under Section 112(r) of Title III of the Clean Air Act Amendments, the US Environmental Protection Agency (EPA) is required to develop regulations that would require development and implementation of risk management programs at facilities that manufacture, process, use, store, or otherwise handle regulated substances in quantities that exceed specified threshold quantities. On January 31, 1994, EPA published the final rule establishing the List of Regulated Substances and Thresholds for Accidental Release Prevention. The proposed rule will require covered facilities to develop and implement a risk management program. The proposed rule will also require facilities to communicate various information to the local emergency planning committee (LEPC). This information may be provided in the form of consultation and communication during the development of various elements of the risk management program and/or by providing access to the risk management plan (RMP). These requirements not only place an additional regulatory burden on facilities but also create the need for the LEPCs to start planning for strategies to deal with significant amount of technical information in a meaningful and effective manner. This paper presents a summary of EPA`s proposed rule, the role of LEPCs in the implementation of many aspects of the rule, and a description of the potential contents of an RMP. Covered facilities as well as the LEPCs may gain a significant advantage by engaging in early dialogue and proactive education to determine mutual needs.

  18. Accidental release prevention: Recent EPA actions

    SciTech Connect

    Mester, Z.C.

    1995-05-01

    Industry should expect a resurgence in EPA accidental release prevention mandates. Among recent federal rulemakings, a list of substances and their thresholds for accidental releases were addressed in a final rule March 1994. Risk management of accidental releases was addressed in a related, proposed rule. The rules will affect an estimated 118,000 facilities nationwide. The Clean Air Act Amendments (CAAA) of 1990 are the driving force. CAAA Title 3 Section 112 (r) requires EPA to formulate and implement requirements for accidental release prevention. Section 112 (r) provisions can be viewed as the culmination of federal legislative efforts to prevent accidental releases and protect the public. Federal interest was fanned by a number of serious accidents in the US and worldwide in the past 20 years.
