  4. Radon-contaminated drinking water from private wells: an environmental health assessment examining a rural Colorado mountain community's exposure.

    PubMed

    Cappello, Michael Anthony; Ferraro, Aimee; Mendelsohn, Aaron B; Prehn, Angela Witt

    2013-11-01

    In the study discussed in this article, 27 private drinking water wells located in a rural Colorado mountain community were sampled for radon contamination and compared against (a) the U.S. Environmental Protection Agency's (U.S. EPA's) proposed maximum contaminant level (MCL), (b) the U.S. EPA proposed alternate maximum contaminate level (AMCL), and (c) the average radon level measured in the local municipal drinking water system. The data from the authors' study found that 100% of the wells within the study population had radon levels in excess of the U.S. EPA MCL, 37% were in excess of the U.S. EPA AMCL, and 100% of wells had radon levels greater than that found in the local municipal drinking water system. Radon contamination in one well was found to be 715 times greater than the U.S. EPA MCL, 54 times greater than the U.S. EPA AMLC, and 36,983 times greater than that found in the local municipal drinking water system. According to the research data and the reviewed literature, the results indicate that this population has a unique and elevated contamination profile and suggest that radon-contaminated drinking water from private wells can present a significant public health concern.

    The omega-3 fatty acid eicosapentaenoic acid (EPA) has multiple actions potentially conferring cardiovascular benefit, including lowering serum triglyceride (TG) and non-high-density lipoprotein cholesterol (non-HDL-C) levels and potentially reducing key steps in atherogenesis. Dietary supplements are a common source of omega-3 fatty acids in the US, but virtually all contain docosahexaenoic acid (DHA) in addition to EPA, and lipid effects differ between DHA and EPA. Contrary to popular belief, no over-the-counter omega-3 products are available in the US, only prescription products and dietary supplements. Among the US prescription omega-3 products, only one contains EPA exclusively (Vascepa); another closely related prescription omega-3 product also contains highly purified EPA, but is approved only in Japan and is provided in different capsule sizes. These high-purity EPA products do not raise low-density lipoprotein cholesterol (LDL-C) levels, even in patients with TG levels >500 mg/dL, in contrast to the increase in LDL-C levels with prescription omega-3 products that also contain DHA. The Japanese prescription EPA product was shown to significantly reduce major coronary events in hypercholesterolemic patients when added to statin therapy in the Japan EPA Lipid Intervention Study (JELIS). The effects of Vascepa on cardiovascular outcomes are being investigated in statin-treated patients with high TG levels in the Reduction of Cardiovascular Events With EPA-Intervention Trial (REDUCE-IT).

    The US Environmental Protection Agency celebrated its 25th anniversary in December 1995. As it is when humans reach an important anniversary, EPA has now embarked on its next 25 years. It does so at a time when it is promoting the successes of the past decade and a half while at the same time is absorbing criticism and budget reductions in Congress. To look both back and ahead, the first US EPA administrator, William Ruckelshaus, now chairman of Browning-Ferris Industries, Inc. (BFI, Houston), was interviewed specifically about EPA`s solid waste programs and policies. Ruckelshaus was EPA administrator from 1970 tomore » 1973 and again from 1983 to 1984.

    EPA Pesticide Factsheets

    EPA announced the availability of the final report, Child-Specific Exposure Scenarios Examples. This report is intended to be a companion document to the Exposure Factors Handbook (U.S. EPA 2011). The example scenarios were compiled from questions and inquiries received from users of the Exposure Factors Handbook (EFH) on how to select data from the EFH to assess childhood exposures. The scenarios presented in this report promote the use of the standard set of age groups recommended by the U.S. EPA in the report entitled Guidance on Selecting Age Groups for Monitoring and Assessing Childhood Exposures to Environmental Contaminants (U.S. EPA 2005). The purpose of the Child-Specific Exposure Scenarios Examples Report is to outline scenarios for various child-specific exposure pathways and to demonstrate how data from the Exposure Factors Handbook (U.S. EPA, 2011) may be applied for estimating exposures. The handbook provides data on drinking water consumption, soil ingestion, mouthing behavior, inhalation rates, dermal factors including skin area and soil adherence factors, consumption of fruits and vegetables, fish, meats, dairy products, homegrown foods, human milk, activity patterns, body weight, and consumer products. The example scenarios presented here have been selected to best demonstrate the use of the various key data sets in the Child-Specific Exposure Factors Handbook (U.S. EPA, 2008a), and represent commonly encountered exposure pathways.

    2002-01-01

    In the early 1990s, the U.S. Environmental Protection Agency (U.S. EPA) started a grant program to assist communities redevelop brownfields, which are abandoned or underutilized sites that have real or perceived contamination. In addition to determining if the communities receiving the grants were the most distressed cities in the United States, we also evaluate the U.S. EPA program in terms of environmental justice at the macro scale. Using 1990 U.S. Census of Housing and Population data and a matched-cities methodology, we compared the brownfields pilot cities to other communities in the United States. We found that regardless of intent, the U.S. EPA program is environmentally just by disproportionately awarding grants to the most economically distressed cities. We also found that the cities that received funding in the early years of the program were more economically distressed than cities receiving the funding more recently. PMID:11929735

The series of presentations will highlight a collaborative effort between the U.S. Environmental Protection Agency (EPA) and the Agency for Science, Technology and Research (A*STAR) that is focused on developing and applying experimental and computational models for predicting chemical-induced liver and kidney toxicity, brain angiogenesis, and blood-brain-barrier formation. In addressing some of these challenges, the U.S. EPA and A*STAR collaboration will provide a glimpse of what chemical risk assessments could look like in the 21st century. Presentation on US EPA – A*STAR Partnership at international symposium on Accelerating the acceptance of next-generation sciences and their application to regulatory risk assessment in Singapore.

    Electric utilities operating nuclear power plants have found themselves in a regulatory Catch-22; extremely limited treatment and disposal capacity is available for their mixed wastes, yet EPA has interpreted RCRA in such a way that long-term storage of the wastes is prohibited. A group of utilities received no relief from this predicament when a court recently rejected their petition for review of EPA`s interpretation of the RCRA mixed-waste storage prohibition. The decision was rendered by the U.S. Court of Appeals for the District of Columbia Circuit on June 18, 1993 (Edison Electric Institute et al. v. U.S. EPA, Docket Number:more » 91-1586).« less

  8. Interpreting biomonitoring data for 2,4-dichlorophenoxyacetic acid: Update to Biomonitoring Equivalents and population biomonitoring data.

    PubMed

    Aylward, L L; Hays, S M

    2015-12-01

    Urinary biomonitoring data for 2,4-dichlorophenoxyacetic acid (2,4-D) reflect aggregate population exposures to trace 2,4-D residues in diet and the environment. These data can be interpreted in the context of current risk assessments by comparison to a Biomonitoring Equivalent (BE), which is an estimate of the average biomarker concentration consistent with an exposure guidance value such as the US EPA Reference Dose (RfD). BE values are updated here from previous published BE values to reflect a change in the US EPA RfD. The US EPA RfD has been updated to reflect a revised point of departure (POD) based on new information from additional toxicological studies and updated assessment of applicable uncertainty factors. In addition, new biomonitoring data from both the US National Health and Nutrition Examination Survey (NHANES) and the Canadian Health Measures Survey (CHMS) have been published. The updated US EPA chronic RfD of 0.21 mg/kg-d results in updated BE values of 10,500 and 7000 μg/L for adults and children, respectively. Comparison of the current population-representative data to these BE values shows that upper bound population biomarker concentrations are more than 5000-fold below BE values corresponding to the updated US EPA RfD. This biomonitoring-based risk assessment supports the conclusion that current use patterns in the US and Canada result in incidental exposures in the general population that can be considered negligible in the context of the current 2,4-D risk assessment.

    Over a decade ago, the electricity consumption associated with home electronics and other small appliances emerged onto the global energy policy landscape as one of the fastest growing residential end uses with the opportunity to deliver significant energy savings. As our knowledge of this end use matures, it is essential to step back and evaluate the degree to which energy efficiency programs have successfully realized energy savings and where savings opportunities have been missed.For the past fifteen years, we have quantified energy, utility bill, and carbon savings for US EPA?s ENERGY STAR voluntary product labeling program. In this paper, wemore » present a unique look into the US residential program savings claimed to date for EPA?s ENERGY STAR office equipment, consumer electronics, and other small household appliances as well as EPA?s projected program savings over the next five years. We present a top-level discussion identifying program areas where EPA?s ENERGY STAR efforts have succeeded and program areas where ENERGY STAR efforts did not successfully address underlying market factors, technology issues and/or consumer behavior. We end by presenting the magnitude of ?overlooked? savings.« less

    EPA Pesticide Factsheets

    A request for technical collaboration between the UNEP and the US EPA resulted in the establishment of a MCRADA. The purpose of this agreement was to evaluate an air quality monitoring system (referred to as the UNEP pod) developed by the UNEP for use in environmental situations where more sophisticated monitoring instrumentation was not available. The US EPA has conducted numerous evaluations of other similar sensor pods at its Research Triangle Park, NC research campus and has trained staff as well as established research designs for such efforts. Under the terms of the MCRADA, the US EPA would operate the pod using UNEP provided operating procedures in a manner consistent with its planned intent of deployment. The US EPA would collect air quality monitoring data from the pod involving select environmental measures over a period of approximately one month. Reference monitoring data collected from collocated federal regulatory monitors would be used to establish a comparison between the two systems and thus establishment of performance characteristics. In addition, the US EPA would provide feedback information to the UNEP as to observed ease of use features of the pod that would be beneficial in its future evolution and deployment. The UNEP recently developed a multipollutant sensor pod called the UNEP Air Quality Monitoring Unit, herein simply defined as the UNEP pod (http://aqicn.org/faq/2015-10-28/unep-air-quality-monitoring-station/).

    EPA Pesticide Factsheets

    In the U.S., a single comprehensive approach to all-hazards domestic incident management has been established by the Department of Homeland Security through the National Response Framework. This helps prevent, prepare for, respond to, and recover from terrorist attacks, major disasters, and other emergencies. A significant component of responding to and recovering from wide-area or isolated events, whether natural, accidental, or intentional, is the management of waste resulting from the incident itself or from activities cleaning up after the incident. To facilitate the proper management of incident-derived waste, EPA developed the Incident Waste Assessment and Tonnage Estimator (I-WASTE). I-WASTE was developed by the U.S. EPA’s Homeland Security Research Program in partnership with EPA program and regional offices, other U.S. government agencies, industry, and state and local emergency response programs.

    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.

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Morehouse, K.

    1995-12-01

    During the 15 years that the U.S. Environmental Protection Agency (EPA) has supported university-based research centers, there have been many changes in mission, operating style, funding level, eligibility, and selection process. Even the definition of the term {open_quotes}research center{close_quotes} is open to debate. Shifting national priorities, political realities, and funding uncertainties have powered the evolution of research centers in EPA, although the agency`s basic philosophy on the purpose and value of this approach to research remains essentially unchanged. Today, EPA manages 28 centers, through the Office of Exploratory Research. These centers are administered under three distinct programs. Each program hasmore » its own mission and goals which guide the way individual centers are selected and operated. This paper will describe: (1) EPA`s philosophy of reserach centers, (2) the complicated history of EPA research centers, (3) coordination and interaction among EPA centers and others, (4) opportunities for collaboration, and (5) plans for the future.« less

  4. History of EPI Suite™ and future perspectives on chemical property estimation in US Toxic Substances Control Act new chemical risk assessments.

    PubMed

    Card, Marcella L; Gomez-Alvarez, Vicente; Lee, Wen-Hsiung; Lynch, David G; Orentas, Nerija S; Lee, Mari Titcombe; Wong, Edmund M; Boethling, Robert S

    2017-03-22

    Chemical property estimation is a key component in many industrial, academic, and regulatory activities, including in the risk assessment associated with the approximately 1000 new chemical pre-manufacture notices the United States Environmental Protection Agency (US EPA) receives annually. The US EPA evaluates fate, exposure and toxicity under the 1976 Toxic Substances Control Act (amended by the 2016 Frank R. Lautenberg Chemical Safety for the 21 st Century Act), which does not require test data with new chemical applications. Though the submission of data is not required, the US EPA has, over the past 40 years, occasionally received chemical-specific data with pre-manufacture notices. The US EPA has been actively using this and publicly available data to develop and refine predictive computerized models, most of which are housed in EPI Suite™, to estimate chemical properties used in the risk assessment of new chemicals. The US EPA develops and uses models based on (quantitative) structure-activity relationships ([Q]SARs) to estimate critical parameters. As in any evolving field, (Q)SARs have experienced successes, suffered failures, and responded to emerging trends. Correlations of a chemical structure with its properties or biological activity were first demonstrated in the late 19 th century and today have been encapsulated in a myriad of quantitative and qualitative SARs. The development and proliferation of the personal computer in the late 20 th century gave rise to a quickly increasing number of property estimation models, and continually improved computing power and connectivity among researchers via the internet are enabling the development of increasingly complex models.

  1. Aquatic toxicity of petroleum products and dispersant agents ...

    EPA Pesticide Factsheets

    The U.S. EPA Office of Research and Development has developed baseline data on the ecotoxicity of selected petroleum products and several chemical dispersants as part of its oil spills research program. Two diluted bitumens (dilbits) from the Alberta Tar Sands were tested for acute and chronic toxicity to standard freshwater and marine organisms given their spill potential during shipment within the United States. Separately, two reference crude oils representing a range of characteristics, and their mixtures with four representative dispersants, were tested to evaluate acute and chronic toxicity to marine organisms in support of Subpart J of the U.S. National Contingency Plan. Water accommodated fractions (WAF) of oil were prepared using traditional slow-stir methods and toxicity tests generally followed U.S. EPA standard effluent testing guidelines. WAFs were characterized for petroleum hydrocarbons including alkyl PAH homologs. The results of these studies will assist the U.S. EPA to assess toxicity data for unconventional oils (dilbits), and establish baseline toxicity data for selected crude oils and dispersant in support of planning and response activities.

    2009-01-01

    Objective Thousands of chemicals are in common use, but only a portion of them have undergone significant toxicologic evaluation, leading to the need to prioritize the remainder for targeted testing. To address this issue, the U.S. Environmental Protection Agency (EPA) and other organizations are developing chemical screening and prioritization programs. As part of these efforts, it is important to catalog, from widely dispersed sources, the toxicology information that is available. The main objective of this analysis is to define a list of environmental chemicals that are candidates for the U.S. EPA screening and prioritization process, and to catalog the available toxicology information. Data sources We are developing ACToR (Aggregated Computational Toxicology Resource), which combines information for hundreds of thousands of chemicals from > 200 public sources, including the U.S. EPA, National Institutes of Health, Food and Drug Administration, corresponding agencies in Canada, Europe, and Japan, and academic sources. Data extraction ACToR contains chemical structure information; physical–chemical properties; in vitro assay data; tabular in vivo data; summary toxicology calls (e.g., a statement that a chemical is considered to be a human carcinogen); and links to online toxicology summaries. Here, we use data from ACToR to assess the toxicity data landscape for environmental chemicals. Data synthesis We show results for a set of 9,912 environmental chemicals being considered for analysis as part of the U.S. EPA ToxCast screening and prioritization program. These include high-and medium-production-volume chemicals, pesticide active and inert ingredients, and drinking water contaminants. Conclusions Approximately two-thirds of these chemicals have at least limited toxicity summaries available. About one-quarter have been assessed in at least one highly curated toxicology evaluation database such as the U.S. EPA Toxicology Reference Database, U.S. EPA Integrated Risk Information System, and the National Toxicology Program.

    Pursuant to the Clean Air Act, the U.S. Environmental Protection Agency (EPA) announced in 2009 its intent to issue rules for controlling emissions from Navajo Generating Station that could affect visibility at the Grand Canyon and at several other national parks and wilderness areas. The final rule will conform to what EPA determines is the best available retrofit technology (BART) for the control of haze-causing air pollutants, especially nitrogen oxides. While EPA is ultimately responsible for setting Navajo Generating Station's BART standards in its final rule, it will be the U.S. Department of the Interior's responsibility to manage compliance andmore » the related impacts.

Health impacts of wildfire smoke merit the attention and action of the US EPA and current research is supported in the ACE and SHC Research Programs. Wildland fire smoke research has taken on greater importance because the 1) contribution of wildland fire PM emissions relative to total US PM emissions is increasing, 2) the population health impacts are measurable and costly, 3) vulnerable and sensitive populations at-risk are increasing attendant to our aging U.S. population and the increasing area of the wildland-urban interface, and 4) health impacts of smoke could be minimized by identifying at-risk individuals and reducing their exposures. Examples are provided.

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

    PubMed

    Kavlock, Robert; Dix, David

    2010-02-01

    Computational toxicology is the application of mathematical and computer models to help assess chemical hazards and risks to human health and the environment. Supported by advances in informatics, high-throughput screening (HTS) technologies, and systems biology, the U.S. Environmental Protection Agency EPA is developing robust and flexible computational tools that can be applied to the thousands of chemicals in commerce, and contaminant mixtures found in air, water, and hazardous-waste sites. The Office of Research and Development (ORD) Computational Toxicology Research Program (CTRP) is composed of three main elements. The largest component is the National Center for Computational Toxicology (NCCT), which was established in 2005 to coordinate research on chemical screening and prioritization, informatics, and systems modeling. The second element consists of related activities in the National Health and Environmental Effects Research Laboratory (NHEERL) and the National Exposure Research Laboratory (NERL). The third and final component consists of academic centers working on various aspects of computational toxicology and funded by the U.S. EPA Science to Achieve Results (STAR) program. Together these elements form the key components in the implementation of both the initial strategy, A Framework for a Computational Toxicology Research Program (U.S. EPA, 2003), and the newly released The U.S. Environmental Protection Agency's Strategic Plan for Evaluating the Toxicity of Chemicals (U.S. EPA, 2009a). Key intramural projects of the CTRP include digitizing legacy toxicity testing information toxicity reference database (ToxRefDB), predicting toxicity (ToxCast) and exposure (ExpoCast), and creating virtual liver (v-Liver) and virtual embryo (v-Embryo) systems models. U.S. EPA-funded STAR centers are also providing bioinformatics, computational toxicology data and models, and developmental toxicity data and models. The models and underlying data are being made publicly available through the Aggregated Computational Toxicology Resource (ACToR), the Distributed Structure-Searchable Toxicity (DSSTox) Database Network, and other U.S. EPA websites. While initially focused on improving the hazard identification process, the CTRP is placing increasing emphasis on using high-throughput bioactivity profiling data in systems modeling to support quantitative risk assessments, and in developing complementary higher throughput exposure models. This integrated approach will enable analysis of life-stage susceptibility, and understanding of the exposures, pathways, and key events by which chemicals exert their toxicity in developing systems (e.g., endocrine-related pathways). The CTRP will be a critical component in next-generation risk assessments utilizing quantitative high-throughput data and providing a much higher capacity for assessing chemical toxicity than is currently available.

  12. An evaluation of freshwater mussel toxicity data in the derivation of water quality guidance and standards for copper

    2007-01-01

    The state of Oklahoma has designated several areas as freshwater mussel sanctuaries in an attempt to provide freshwater mussel species a degree of protection and to facilitate their reproduction. We evaluated the protection afforded freshwater mussels by the U.S. Environmental Protection Agency (U.S. EPA) hardness-based 1996 ambient copper water quality criteria, the 2007 U.S. EPA water quality criteria based on the biotic ligand model and the 2005 state of Oklahoma copper water quality standards. Both the criterion maximum concentration and criterion continuous concentration were evaluated. Published acute and chronic copper toxicity data that met American Society for Testing and Materials guidance for test acceptability were obtained for exposures conducted with glochidia or juvenile freshwater mussels. We tabulated toxicity data for glochidia and juveniles to calculate 20 species mean acute values for freshwater mussels. Generally, freshwater mussel species mean acute values were similar to those of the more sensitive species included in the U.S. EPA water quality derivation database. When added to the database of genus mean acute values used in deriving 1996 copper water quality criteria, 14 freshwater mussel genus mean acute values included 10 of the lowest 15 genus mean acute values, with three mussel species having the lowest values. Chronic exposure and sublethal effects freshwater mussel data available for four species and acute to chronic ratios were used to evaluate the criterion continuous concentration. On the basis of the freshwater mussel toxicity data used in this assessment, the hardness-based 1996 U.S. EPA water quality criteria, the 2005 Oklahoma water quality standards, and the 2007 U.S. EPA water quality criteria based on the biotic ligand model might need to be revised to afford protection to freshwater mussels. ?? 2007 SETAC.

    2009-09-24

    This report provides a top-level summary of national savings achieved by the Energy Star voluntary product labeling program. To best quantify and analyze savings for all products, we developed a bottom-up product-based model. Each Energy Star product type is characterized by product-specific inputs that result in a product savings estimate. Our results show that through 2007, U.S. EPA Energy Star labeled products saved 5.5 Quads of primary energy and avoided 100 MtC of emissions. Although Energy Star-labeled products encompass over forty product types, only five of those product types accounted for 65percent of all Energy Star carbon reductions achieved tomore » date, including (listed in order of savings magnitude)monitors, printers, residential light fixtures, televisions, and furnaces. The forecast shows that U.S. EPA?s program is expected to save 12.2 Quads of primary energy and avoid 215 MtC of emissions over the period of 2008?2015.« less

  15. Ten Years of Addressing Children’s Health through Regulatory Policy at the U.S. Environmental Protection Agency

    PubMed Central

    Payne-Sturges, Devon; Kemp, Debra

    2008-01-01

    Background Executive Order (EO) 13045, Protection of Children From Environmental Health Risks and Safety Risks, directs each federal agency to ensure that its policies, programs, activities, and standards address disproportionate environmental health and safety risks to children. Objectives We reviewed regulatory actions published by U.S. Environmental Protection Agency (EPA) in the Federal Register from April 1998 through December 2006 to evaluate applicability of EO 13045 to U.S. EPA actions and consideration of children’s health issues in U.S. EPA rulemakings. Discussion Although virtually all actions discussed EO 13045, fewer than two regulations per year, on average, were subject to the EO requirement to evaluate children’s environmental health risks. Nonetheless, U.S. EPA considered children’s environmental health in all actions addressing health or safety risks that may disproportionately affect children. Conclusion The EO does not apply to a broad enough set of regulatory actions to ensure protection of children’s health and safety risks, largely because of the small number of rules that are economically significant. However, given the large number of regulations that consider children’s health issues despite not being subject to the EO, other statutory requirements and agency policies reach a larger set of regulations to ensure protection of children’s environmental health.

    John Paul; Eddie Terrill

    2006-06-15

    Several aspects of the US EPA's recent proposal to revise the particulate matter (PM) standards deeply concern state and local air agencies and their representatives with the State and Territorial Air Pollution Program Administrators and the Association of Local Air Pollution Control Offices (STAPPA and ALAPCO). STAPPA and ALAPCO urge EPA to follow the recommendations of its appointed scientific experts and lower the annual average standard to 13 or 14 {mu}mg/m{sup 3} in addition to lowering the daily standard to 35 {mu}m/m{sup 3}. Unless EPA strengthens its proposal consistent with the recommendations of the Clean Air Scientific Advisory Committee (CASAC),more » STAPPA and ALAPCO are extremely concerned that we will continue to see significant increased premature mortality and adverse health effects throughout the country. For the reasons described in the article STAPPA and ALAPCO urge EPA to eliminate the exemptions for agriculture, mining and rural windblown dust. STAPPA and ALAPCO are troubled that EPA has ignored any commitment to funding the proposed coarse PM network scheduled for deployment in Fiscal Year (FY) 2008. EPA has estimated that the capital costs of this monitoring network could easily exceed US$ 14 million, with annual operating expenses of approximately US$ 13 million. State and local agencies will simply not be able to assume these significant costs. 33 refs.« less

  6. Comparison of US EPA and European emission standards for combustion and incineration technologies

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Licata, A.; Hartenstein, H.U.; Terracciano, L.

    1997-12-01

    There has been considerable debate, misunderstanding, and controversy when comparing emission standards used in Europe and the United States. One of the first questions you hear whenever U.S. EPA publishes a new emission standard is, {open_quotes}Is it as restrictive or is it the same as the German standard{close_quotes}. Although both systems of regulation call for the use of CEMS for compliance, there are substantial differences in how emission standards are structured in Europe and in the U.S. They include reference points, averaging times, sampling methods, and technology. Generally, the European standards tend to be more restrictive, due in part tomore » the fact that the facilities are of necessity sited in close proximity to residential areas. In Germany, for example, regulations in general are comprehensive and include both design standards and emission limits while U.S. EPA`s rules are source specific and, in most cases, limited to numerical emission standards. In some cases, comparisons can be made between emission standards and, in some cases, comparisons can only be made with restrictive caveats. The paper will present a comprehensive overview of the emission standards and how they are applied.« less

  7. Implementing the NPDES program: An update on the WET ...

    EPA Pesticide Factsheets

    The U.S. EPA has utilized the Clean Water Act - National Pollutant Discharge Elimination System permitting program to protect waters of the U.S for over 40 years. NPDES permit effluent limitations serve as the primary mechanism for controlling discharges of pollutants to receiving waters. When developing effluent limitations for an NPDES permit, a permit writer must consider limits based on both the technology available to control the pollutants (i.e., technology-based effluent limits) and limits that are protective of the water quality standards of the receiving water (i.e., water quality-based effluent limits). WET testing is one of the water quality-based effluent limitation mechanisms available to permit writers that is useful in determining how the additive, synergistic and compounding effects of toxic effluents effect streams. This presentation will provide an overview of the current EPA NPDES permit program direction for increasing the efficacy of NPDES permits program administered by the U.S. EPA and States. The training implementation plan is expected to provide permit writers with a clearer understanding of WET requirements as established via the U.S. EPA WET test manuals, NPDES permitting regulatory authorities, and the WET science which has been long established. not applicable

    2018-05-01

    The Health Physics Society (HPS) provided comment to the U.S. Environmental Protection Agency (EPA) on options to consider when developing an action plan for President Trump's Executive Order to evaluate regulations for repeal, replacement, or modification. The HPS recommended that the EPA reconsider their adherence to the linear no-threshold (LNT) model for radiation risk calculations and improve several documents by better addressing uncertainties in low-dose, low dose-rate (LDDR) radiation exposure environments. The authors point out that use of the LNT model near background levels cannot provide reliable risk projections, use of the LNT model and collective-dose calculations in some EPA documents is inconsistent with the recommendations of international organizations, and some EPA documents have not been exposed to the public comment rule-making process. To assist in establishing a better scientific basis for the risks of low dose rate and low dose radiation exposure, the EPA should continue to support the "Million Worker Study," led by the National Council on Radiation Protection and Measurement.

  15. Chemicals and children's environment: what we don't know about risks.

    PubMed

    Goldman, L R

    1998-06-01

    Although we know that certain types of childhood cancers are increasing, we do not know why. With few exceptions, we know little about the role of environmental carcinogens in childhood cancer. Generally, we have adequate information to screen chemicals for potential hazard for only certain categories of chemicals--drugs, food additives, and pesticides. The U.S. Environmental Protection Agency (U.S. EPA) is implementing the 1996 Food Quality Protection Act, which provides added protections against pesticide risks, especially for children. But the situation is quite different for many industrial chemicals. We lack even basic toxicity data for a majority of the U.S. EPA's list of approximately 3000 nonpolymeric high-production-volume industrial chemicals being produced in the United States each year that are found in consumer products and the workplace. We know even less about the remaining 70,000 chemicals on the U.S. EPA inventory. The U.S. EPA has initiatives underway to address the risks posed by some of these commercial chemicals, including efforts to reduce risks posed by indoor air pollutants and household products. These initiatives specifically address children's risks. We are supporting toxicity screening of high-volume industrial chemicals on a cooperative international basis through the Organisation for Economic Co-operation and Development. Until more information is available, it is difficult to assess the possible role of these chemicals in childhood cancer and to take steps to reduce exposure to children.

  9. Risk assessment for the daily intake of polycyclic aromatic hydrocarbons from the ingestion of cockle (Anadara granosa) and exposure to contaminated water and sediments along the west coast of Peninsular Malaysia.

    PubMed

    Mirsadeghi, Seiedeh Aghileh; Zakari, Mohamad Pauzi; Yap, Chee Kong; Shahbazi, Azadeh

    2011-01-01

    The concentration of carcinogenic polycyclic aromatic hydrocarbons (c-PAHs) present in the sediment and water of Peninsular Malaysia as well as in the cockle Anadara granosa was investigated. Samples were extracted and analysed with gas chromatography-mass spectrometry. The concentrations of total carcinogenic polycyclic aromatic hydrocarbons (t-PAHs) were measured between 0.80 +/- 0.04 to 162.96 +/- 14.74 ng/g wet weight (ww) in sediment, between 21.85 +/- 2.18 to 76.2 +/- 10.82 ng/L in water samples and between 3.34 +/- 0.77 to 46.85 +/- 5.50 ng/g ww in the cockle tissue. The risk assessment of probable human carcinogens in the Group B2 PAHs was calculated and assessed in accordance with the standards of the United States Environmental Protection Agency (US EPA). Case I in the toxicity assessment analysed the cancer risk to consumers of Malaysian blood cockle. Case II assessed the risk of cancer from exposure to PAHs from multiple pathways. The average cancer risk of case I and case II were found to be classifiable as unsafe according to the US EPA standard. The cancer risk due to c-PAHs acquired by the ingestion of blood cockle was (8.82 +/- 0.54) x 10-6 to (2.67 +/- 0.06) x 10(-2), higher than the US EPA risk management criterion. The non-cancer risks associated with multiple pathways in Kuala Gula, Kuala Juru and Kuala Perlis were higher than the U.S. EPA safe level, but the non-cancer risk for eating blood cockle was below the level of U.S. EPA concern.

  10. A comparison of two above-ground biomass estimation techniques integrating satellite-based remotely sensed data and ground data for tropical and semiarid forests in Puerto Rico

    NASA Astrophysics Data System (ADS)

    Iiames, J. S.; Riegel, J.; Lunetta, R.

    2013-12-01

    Two above-ground forest biomass estimation techniques were evaluated for the United States Territory of Puerto Rico using predictor variables acquired from satellite based remotely sensed data and ground data from the U.S. Department of Agriculture Forest Inventory Analysis (FIA) program. The U.S. Environmental Protection Agency (EPA) estimated above-ground forest biomass implementing methodology first posited by the Woods Hole Research Center developed for conterminous United States (National Biomass and Carbon Dataset [NBCD2000]). For EPA's effort, spatial predictor layers for above-ground biomass estimation included derived products from the U.S. Geologic Survey (USGS) National Land Cover Dataset 2001 (NLCD) (landcover and canopy density), the USGS Gap Analysis Program (forest type classification), the USGS National Elevation Dataset, and the NASA Shuttle Radar Topography Mission (tree heights). In contrast, the U.S. Forest Service (USFS) biomass product integrated FIA ground-based data with a suite of geospatial predictor variables including: (1) the Moderate Resolution Imaging Spectrometer (MODIS)-derived image composites and percent tree cover; (2) NLCD land cover proportions; (3) topographic variables; (4) monthly and annual climate parameters; and (5) other ancillary variables. Correlations between both data sets were made at variable watershed scales to test level of agreement. Notice: This work is done in support of EPA's Sustainable Healthy Communities Research Program.

  11. Pharmaceuticals and Personal Care Products in Archived U.S. Biosolids from the 2001 EPA National Sewage Sludge Survey

    PubMed Central

    McClellan, Kristin; Halden, Rolf U.

    2010-01-01

    In response to the U.S. National Academies’ call for a better assessment of chemical pollutants contained in the approximately 6.9 million dry tons of digested municipal sludge produced annually in the United States, the mean concentration of 72 pharmaceuticals and personal care products (PPCP) were determined in 110 biosolids samples collected by the U.S. Environmental Protection Agency (EPA) in its 2001 National Sewage Sludge Survey. Composite samples of archived biosolids, collected at 94 U.S. wastewater treatment plants from 32 states and the District of Columbia, were analyzed by liquid chromatography tandem mass spectrometry using EPA Method 1694. Thirty-eight (54%) of the 72 analytes were detected in at least one composite sample at concentrations ranging from 0.002 to 48 mg kg−1 dry weight. Triclocarban and triclosan were the most abundant analytes with mean concentrations of 36 ± 8 and 12.6 ± 3.8 mg kg−1 (n = 5), respectively, accounting for 65% of the total PPCP mass found. The loading to U.S. soils from nationwide biosolids recycling was estimated at 210–250 metric tons per year for the sum of the 72 PPCPs investigated. The results of this nationwide reconnaissance of PPCPs in archived U.S. biosolids mirror in contaminant occurrences, frequencies and concentrations, those reported by the U.S. EPA for samples collected in 2006/07. This demonstrates that PPCP releases in U.S. biosolids have been ongoing for many years and the most abundant PPCPs appear to show limited fluctuations in mass over time when assessed on a nationwide basis. The here demonstrated use of five mega composite samples holds promise for conducting cost-effective, routine monitoring on a regional basis. PMID:20106500

  7. Comparison of techniques for the detection of helminth ova in drinking water and wastewater.

    Maya, C; Jimenez, B; Schwartzbrod, J

    2006-02-01

    Many countries use wastewater for irrigation. The World Health Organization established, as reuse guidelines, a maximum value of 1 helminth ovum/L for irrigation. Various techniques for enumerating helminth ova in water have been published. To determine the most adequate method for Mexico, four techniques were compared: the U.S. Environmental Protection Agency (U.S. EPA), membrane-filter, Leeds I, and Faust. Two types of water were used: drinking water and municipal wastewater effluent. Sensitivity, discrimination coefficients, precision, recovery efficiency, and cost were determined. In addition, several unseeded wastewater samples were analyzed. For drinking water, U.S. EPA and the membrane-filter techniques demonstrated comparable results; however, when wastewater was used, the membrane technique showed some deficiencies. Because the U.S. EPA technique may be used for samples with both high and low solids content, allows for the recovery of helminth ova with different specific gravities, and has the lowest total cost, it was selected as the best technique.

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    HOWARD,BRYAN A.; CRAWFORD,M.B.; GALSON,D.A.

    2000-05-22

    The Waste Isolation Pilot Plant (WIPP) is the first operational repository designed for the safe disposal of transuranic (TRU) radioactive waste from the defense programs of the US Department of Energy (DOE). The US Environmental Protection Agency (EPA) is responsible for certifications and regulation of the WIPP facility for the radioactive components of the waste. The EPA has promulgated general radioactive waste disposal standards at 40 CFR Part 191. and WIPP-specific criteria to implement and interpret the generic disposal standards at 40 CFR Part 194. In October 1996. the DOE submitted its Compliance Certification Application (CCA) to the EPA tomore » demonstrate compliance with the disposal standards at Subparts B and C of 40 CFR Part 191. This paper summarizes the development of the overall legal framework for radioactive waste disposal at the WIPP, the parallel development of the WIPP performance assessment (PA), and how the EPA disposal standards and implementing criteria formed the basis for the CCA WIPP PA. The CCA resulted in a certification in May 1998 by the EPA of the WIPP'S compliance with the EPA's disposal standard, thus enabling the WIPP to begin radioactive waste disposal.« less

    2005-01-01

    When the U.S. Environmental Protection Agency (EPA) finalized its 2000 update of the toxicological effects of vinyl chloride (VC), it was concerned with two issues: the classification of VC as a carcinogen and the numerical estimate of its potency. In this commentary we describe how the U.S. EPA review of VC toxicology, which was drafted with substantial input from the chemical industry, weakened safeguards on both points. First, the assessment downplays risks from all cancer sites other than the liver. Second, the estimate of cancer potency was reduced 10-fold from values previously used for environmental decision making, a finding that reduces the cost and extent of pollution reduction and cleanup measures. We suggest that this assessment reflects discredited scientific practices and recommend that the U.S. EPA reverse its trend toward ever-increasing collaborations with the regulated industries when generating scientific reviews and risk assessments.

  20. Chemicals and children's environment: what we don't know about risks.

    PubMed Central

    Goldman, L R

    1998-01-01

    Although we know that certain types of childhood cancers are increasing, we do not know why. With few exceptions, we know little about the role of environmental carcinogens in childhood cancer. Generally, we have adequate information to screen chemicals for potential hazard for only certain categories of chemicals--drugs, food additives, and pesticides. The U.S. Environmental Protection Agency (U.S. EPA) is implementing the 1996 Food Quality Protection Act, which provides added protections against pesticide risks, especially for children. But the situation is quite different for many industrial chemicals. We lack even basic toxicity data for a majority of the U.S. EPA's list of approximately 3000 nonpolymeric high-production-volume industrial chemicals being produced in the United States each year that are found in consumer products and the workplace. We know even less about the remaining 70,000 chemicals on the U.S. EPA inventory. The U.S. EPA has initiatives underway to address the risks posed by some of these commercial chemicals, including efforts to reduce risks posed by indoor air pollutants and household products. These initiatives specifically address children's risks. We are supporting toxicity screening of high-volume industrial chemicals on a cooperative international basis through the Organisation for Economic Co-operation and Development. Until more information is available, it is difficult to assess the possible role of these chemicals in childhood cancer and to take steps to reduce exposure to children. PMID:9646051

  1. Animal Use and Lessons Learned in the U.S. High Production Volume Chemicals Challenge Program

    Manuppello, Joseph R.; Willett, Catherine E.; Sandler, Jessica T.

    2012-01-01

    Background: Launched by the U.S. Environmental Protection Agency (EPA) in 1998, the High Production Volume (HPV) Challenge Program was developed to address the perceived gap in basic hazard information for the 2,800 chemicals produced or imported into the United States in quantities of ≥ 1 million pounds per year. Health and environmental effects data obtained from either existing information or through new vertebrate animal testing were voluntarily submitted by chemical companies (sponsors) to the U.S. EPA. Despite the potential for extensive animal testing, animal welfare guidelines were not provided until after the start of the program. Objectives: We evaluated compliance with the animal welfare principles that arose from an agreement reached between the U.S. EPA and animal protection organizations and tracked the HPV program’s use of animals for testing. Discussion: Under a worst-case scenario, the HPV program had the potential to consume 3.5 million animals in new testing. After application of animal-saving measures, approximately 127,000 were actually used. Categorization of chemicals based on similar structure–activity and application of read-across, along with use of existing test data, were the most effective means of reducing animal testing. However, animal-saving measures were inconsistently used by both sponsors and the U.S. EPA. Conclusions: Lessons learned from the HPV program can be applied to future programs to minimize animal testing and promote more human-relevant chemical risk assessment. PMID:23033452

  2. Constructing a Spatially Resolved Methane Emission Inventory of Natural Gas Production and Distribution over Contiguous United States

    NASA Astrophysics Data System (ADS)

    Li, X.; Omara, M.; Adams, P. J.; Presto, A. A.

    2017-12-01

    Methane is the second most powerful greenhouse gas after Carbon Dioxide. The natural gas production and distribution accounts for 23% of the total anthropogenic methane emissions in the United States. The boost of natural gas production in U.S. in recent years poses a potential concern of increased methane emissions from natural gas production and distribution. The Emission Database for Global Atmospheric Research (Edgar) v4.2 and the EPA Greenhouse Gas Inventory (GHGI) are currently the most commonly used methane emission inventories. However, recent studies suggested that both Edgar v4.2 and the EPA GHGI largely underestimated the methane emission from natural gas production and distribution in U.S. constrained by both ground and satellite measurements. In this work, we built a gridded (0.1° Latitude ×0.1° Longitude) methane emission inventory of natural gas production and distribution over the contiguous U.S. using emission factors measured by our mobile lab in the Marcellus Shale, the Denver-Julesburg Basin, and the Uintah Basin, and emission factors reported from other recent field studies for other natural gas production regions. The activity data (well location and count) are mostly obtained from the Drillinginfo, the EPA Greenhouse Gas Reporting Program (GHGRP) and the U.S. Energy Information Administration (EIA). Results show that the methane emission from natural gas production and distribution estimated by our inventory is about 20% higher than the EPA GHGI, and in some major natural gas production regions, methane emissions estimated by the EPA GHGI are significantly lower than our inventory. For example, in the Marcellus Shale, our estimated annual methane emission in 2015 is 600 Gg higher than the EPA GHGI. We also ran the GEOS-Chem methane simulation to estimate the methane concentration in the atmosphere with our built inventory, the EPA GHGI and the Edgar v4.2 over the nested North American Domain. These simulation results showed differences in some major gas production regions. The simulated methane concentrations will be compared with the GOSAT satellite data to explore whether our built inventory could potentially improve the prediction of regional methane concentrations in the atmosphere.

    EPA Pesticide Factsheets

    EPA announced the availability of the final report, An Approach to Using Toxicogenomic Data in U.S. EPA Human Health Risk Assessments: A Dibutyl Phthalate Case Study. This report outlines an approach to evaluate genomic data for use in risk assessment and a case study to illustrate the approach. The dibutyl phthalate (DBP) case study example focuses on male reproductive developmental effects and the qualitative application of genomic data because of the available data on DBP. The case study presented in this report is a separate activity from any of the ongoing IRIS human health assessments for the phthalates. The National Center for Environmental Assessment (NCEA) prepared this document for the purpose of describing and illustrating an approach for using toxicogenomic data in risk assessment.

  20. A novel cost-effectiveness model of prescription eicosapentaenoic acid extrapolated to secondary prevention of cardiovascular diseases in the United States.

    Given the substantial economic and health burden of cardiovascular disease and the residual cardiovascular risk that remains despite statin therapy, adjunctive therapies are needed. The purpose of this model was to estimate the cost-effectiveness of high-purity prescription eicosapentaenoic acid (EPA) omega-3 fatty acid intervention in secondary prevention of cardiovascular diseases in statin-treated patient populations extrapolated to the US. The deterministic model utilized inputs for cardiovascular events, costs, and utilities from published sources. Expert opinion was used when assumptions were required. The model takes the perspective of a US commercial, third-party payer with costs presented in 2014 US dollars. The model extends to 5 years and applies a 3% discount rate to costs and benefits. Sensitivity analyses were conducted to explore the influence of various input parameters on costs and outcomes. Using base case parameters, EPA-plus-statin therapy compared with statin monotherapy resulted in cost savings (total 5-year costs $29,393 vs $30,587 per person, respectively) and improved utilities (average 3.627 vs 3.575, respectively). The results were not sensitive to multiple variations in model inputs and consistently identified EPA-plus-statin therapy to be the economically dominant strategy, with both lower costs and better patient utilities over the modeled 5-year period. The model is only an approximation of reality and does not capture all complexities of a real-world scenario without further inputs from ongoing trials. The model may under-estimate the cost-effectiveness of EPA-plus-statin therapy because it allows only a single event per patient. This novel model suggests that combining EPA with statin therapy for secondary prevention of cardiovascular disease in the US may be a cost-saving and more compelling intervention than statin monotherapy.
