    SciTech Connect

    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.

  15. 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.

  16. Compounding conservatisms: EPA's health risk assessment methods

    SciTech Connect

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

    1993-03-01

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

    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.

    Knoll, J.E.; Midgett, M.R.

    1980-03-01

    Techniques used in EPA Method 8, the source test method for acid mist and sulfur dioxide emissions from sulfuric acid plants, have been evaluated. Evidence is shown that trace amounts of peroxides in isopropyl alcohol result in the conversion of sulfur dioxide to sulfate and cause positive errors in acid mist values. Methods for measuring and purifying IPA are described. No conversion of sulfur dioxide to sulfate on filters or filter supports were observed. Collection efficiencies of train components are described and two alternate indicators are evaluated. Solid ammonium sulfates's use as audit samples is discussed. Field testing is also described in which paired-probe techniques were employed. They showed that, when sulfur trioxide is absent from the effluent streams, acid mist is efficiently collected by a single filter, even when the isopropyl alcohol-containing impinger is eliminated. Both ammonia and dimethyl analine, which are employed as gas scrubbers, cause sulfur dioxide to be retained in the isopropyl alcohol and result in large positive interferences in acid mist values. Ferric oxide, present in the effluents of steel pickling operations, causes a large negative interference in acid mist values.

    1988-11-01

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

    2006-01-01

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

    Traditionally, the No-Observed-Adverse-Effect-Level (NOAEL) approach has been used to determine the point of departure (POD) from animal toxicology data for use in human health risk assessments. However, this approach is subject to substantial limitations that have been well defined, such as strict dependence on the dose selection, dose spacing, and sample size of the study from which the critical effect has been identified. Also, the NOAEL approach fails to take into consideration the shape of the dose-response curve and other related information. The benchmark dose (BMD) method, originally proposed as an alternative to the NOAEL methodology in the 1980s, addresses many of the limitations of the NOAEL method. It is less dependent on dose selection and spacing, and it takes into account the shape of the dose-response curve. In addition, the estimation of a BMD 95% lower bound confidence limit (BMDL) results in a POD that appropriately accounts for study quality (i.e., sample size). With the recent advent of user-friendly BMD software programs, including the U.S. Environmental Protection Agency's (U.S. EPA) Benchmark Dose Software (BMDS), BMD has become the method of choice for many health organizations world-wide. This paper discusses the BMD methods and corresponding software (i.e., BMDS version 2.1.1) that have been developed by the U.S. EPA, and includes a comparison with recently released European Food Safety Authority (EFSA) BMD guidance.

  4. Implementation of the US EPA (United States Environmental Protection Agency) Regional Oxidant Modeling System

    Novak, J.H.

    1984-05-01

    Model design, implementation and quality assurance procedures can have a significant impact on the effectiveness of long term utility of any modeling approach. The Regional Oxidant Modeling System (ROMS) is exceptionally complex because it treats all chemical and physical processes thought to affect ozone concentration on a regional scale. Thus, to effectively illustrate useful design and implementation techniques, this paper describes the general modeling framework which forms the basis of the ROMS. This framework is flexible enough to allow straightforward update or replacement of the chemical kinetics mechanism and/or any theoretical formulations of the physical processes. Use of the Jackson Structured Programming (JSP) method to implement this modeling framework has not only increased programmer productivity and quality of the resulting programs, but also has provided standardized program design, dynamic documentation, and easily maintainable and transportable code. A summary of the JSP method is presented to encourage modelers to pursue this technique in their own model development efforts. In addition, since data preparation is such an integral part of a successful modeling system, the ROMS processor network is described with emphasis on the internal quality control techniques.

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

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

    Bishop, Patricia L; Willett, Catherine E

    2014-02-01

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

  19. Trivalent chromium solubility and its influence on quantification of hexavalent chromium in ambient particulate matter using EPA method 6800.

    Measurement of carcinogenic Cr(VI) in ambient PM is challenging due to potential errors associated with conversion between Cr (VI) (a carcinogen) and Cr(III) (an essential nutrient). Cr(III) conversion is a particular concern due to its > 80% atomic abundance in total Cr. US. Environmental Protection Agency (EPA) method 6800 that uses water-soluble isotope spikes can be used to correct the interconversion. However, whether the enriched Cr(III) isotope spikes can adequately mimic the Cr(III) species originally in ambient PM is unknown. This study examined the water solubility of Cr(III) in ambient PM and discussed its influence on Cr(VI) measurement. Ambient PM10 samples were collected on Teflon filters at four sites in New Jersey that may have different Cr emission sources. The samples were ultrasonically extracted with 5 mL DI-H2O (pH 5.7) at room temperature for 40 min, and then analyzed by ion chromatography-inductively coupled plasma mass spectrometry (IC-ICPMS). Cr(III) was below detection limit (0.06 ng/m3) for all samples, suggesting water-soluble Cr(III) species, such as CrCl3, Cr(NO3)3, and amorphous Cr(OH)3, in the ambient PM were negligible. Therefore, the enriched 50Cr(III) isotope spike (in the form of Cr(NO3)3) could not mimic the original ambient Cr(III). Only the conversion of 53Cr(VI) (in the form of K2CrO4) was taken into account when correcting the interconversion. We then used NaHCO3-pretreated MCE filters (prespiked with enriched isotope species) to measure Cr(VI) in the ambient PM10. The samples were ultrasonically extracted at 60 C pH 9 solutions for 40 min followed by IC-ICPMS analysis. Due to the correction of Cr(VI) reduction, the Cr(VI) concentrations determined by EPA method 6800, 0.26 ± 0.16 (summer) and 0.16 ± 0.11(winter) ng/m3 (n = 64), were significantly greater than those by the external standard curve, 0.21 ± 0.17 (summer) and 0.10 ± 0.07 (winter) ng/m3 (n = 56) (p < 0.01, Student's t-test).

    Condensible particulate matter (CPM) consists of species which are emitted from a source in the vapor phase at stack gas temperatures but condense into a liquid or solid aerosol at ambient temperatures. The US EPA method for measuring CPM (Reference Method 202) is subject to false positive biases because of conversion of non-particulate species into CPM in the test sampling train. These biases are significant for coal- and oil-fired boilers, and can often be larger than actual particulate emissions and/or emission limits. In response to these issues, the Electric Power Research Institute (EPRI) retained Fossil Energy Research Corporation (FERCo) to conduct a study to evaluate Method 202 and develop and test alternatives to the method which would eliminate the bias. The program included three phases: (1) a review of technical and regulatory issues related to CPM measurements, (2) evaluation of a variety of possible modifications and alternatives to Method 202, and (3) full scale field testing of two alternatives, the use of reduced filtration temperature with correction for sulfuric acid pseudoparticulate, and use of isopropanol rather than water impingers to collect CPM. This State of the Art Report presents a summary of the current state of CPM measurement from technical and regulatory perspectives, the results of the bench scale and full scale evaluation programs, and recommendations for further field evaluation and for gaining EPA approval of an alternative method that eliminates the positive bias.

    The difficulties associated with the control and transfer of environmental leach methods are discussed. Optimized EPA Method 3015A, a microwave-assisted leach of wastewater and drinking water matrices and aqueous extracts, is evaluated. The option to add HCl in addition to HNO[sub 3] provides better complexation and recovery of certain metals that are regulated by the Resource Conservation and Recovery Act (RCRA) than the original HNO[sub 3]-only Method 3015. Also discussed is the preparation and appropriate use of simulated wastewater standards. Standard reference materials for a wastewater matrix are unavailable, and this novel approach provides NIST-traceability of results for the first time on this matrix type. Leach concentrations from these simulated standards were determined using both the 5 mL HNO[sub 3] and the 4 mL HNO[sub 3] and 1 mL HCl leach options of new Method 3015A. Validation of the new mixed-acid option of Method 3015A has been provided by evaluating its performance on the 23 elements for which original Method 3015 was validated. In addition, validation is provided for boron, mercury, and strontium, elements that were not validated in original Method 3015. Method 3015A has been developed into a method capable of evaluating 26 elements in a single, efficient, 20-min procedure.

    1995-09-01

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

    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.

    Barth, E.A.

    1982-08-01

    This document announces the conclusions of the EPA evaluation of the POLARION-X device under the provisions of Section 511 of the Motor Vehicle Information and Cost Savings Act. The evaluation of the POLARION-X device was conducted upon receiving an application from the marketer of the device. The POLARION-X is installed in the fuel line between the pump and the carburetor. It incorporates two permanent magnets which subject the fuel to a magnetic field. This device is claimed to reduce emissions, to improve fuel economy and performance, to provide more complete combustion, to eliminate engine carbon buildup and dieseling, and to reduce the octane requirements of the engine. The Environmental Protection Agency (EPA) fully considered all of the information submitted by the applicant. The overall conclusion was that for the POLARION-X there is no reason to expect that the device will improve either the emissions or fuel economy of a typical motor vehicle in proper operating conditions.

    The Cold Weather Plume Study (CWPS) was a field measurement program carried out in February 1981 under the joint sponsorship of the U.S. Environmental Protection Agency and the Electric Power Research Institute. Its objective was to generate a data base suitable for quantitative analysis of the mesoscale physical dynamics and SOx, NOx chemistry of the plume of the 1320-MW coal-fired Kincaid power plant near Springfield, Illinois. The data base was intended to complement similar measurements made by other EPA and EPRI studies in the same region during other seasons. Measurements included in-situ chemical measurements from two instrumented aircraft, remote-sensing lidar measurements and meteorological measurements from a surface station, two towers, and from vertical soundings. The report provides a brief overview of the measurement platforms, the measured parameters, and the daily experiments, and describes and documents the data base available on magnetic tapes and in hard copy form.

    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.

    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.

    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.

  15. Regional Comparisons of Coastal Sediment Contamination Detected by a Biomarker (P450 HRGS; EPA Method 4425)

    2005-01-01

    Pollution investigations by the Center for Coastal Assessment and Monitoring of the National Oceanic and Atmospheric Administration (NOAA) have been conducted since 1984 and have incorporated extensive biological and chemical analyses. Since 1993, one of the suites of biological tests utilized in these studies has been the biomarker P450HRGS, which is more recently referred to as EPA Method 4425. Extracts of sediments are applied to a human cell line with a reporter gene at the CYP1A1 site. Light produced by the extracts is a function of the concentrations and potencies of those compounds with an affinity for Ah-receptor (polycyclic aromatic hydrocarbons [PAHs], polychlorinated biphenyls [PCBs], dioxins/furans). These compounds are carcinogenic, can produce chronic toxicity, and those containing chlorine are persistent and bioaccumulated. Nineteen coastal regions and 1309 samples from the three U.S. coasts have been evaluated as part of the NOAA investigations. The stratified random sampling approach used by NOAA provides estimates of the areas (km2) of each region containing levels of the compounds above thresholds. From analysis of the data base, sediments with concentrations at or below 11 ?g benzo[a]pyrene equivalents (B[a]PEq)/g would not be expected to produce effects on the benthos. At 32 ?g B[a]PEq/g and above there is the potential for impacts on the biota, and above 60 ?g/g, the degradation of the benthic community has been observed. Several of the regional surveys found no samples at or above 60 ?g B[a]PEq/g, but 60% of the samples from New York Harbor (280 km2) were above this level. Analyses of data from Puget Sound and Chesapeake Bay demonstrate an increase in samples above 32 ?g B[a]PEq/g in more populated and industrial regions. A targeted investigation of the distribution of the three important classes of compounds identified by Method 4425 would be more cost effective by first screening samples by this method before expending substantial funds in

    Seven polychlorinated dibenzo-p-dioxins (PCDDs), ten polychlorinated dibenzofurans (PCDFs) as well as twelve polychlorinated biphenyls (PCBs) are collectively referred to as dioxin-like compounds. The World Health Organization toxic equivalency factors (TEFs) for these persistent chlorinated organic compounds and their measured concentrations are used to produce the toxic equivalency quotient (TEQ) of a sample. TEF values are partially based on a common mechanism involving binding of the chemical to the aryl hydrocarbon receptor (AhR). Biological methods for the determination of TEQs are based on the assumption that all dioxin-related compounds act through the Ah receptor signal transduction pathway. Based on the biochemical response of CYP1A activation via the AhR, in vitro systems that utilize a reporter gene under transcriptional control of CYP1A have been developed. Several investigations have reported on the success of utilizing biological test systems to detect PCDDs, PCDFs, PCBs in environmental samples. The P450 Human Reporter Gene System assay (EPA Method 4425) utilizes a human hepatoma cell line (HepG2) in which a plasmid containing the human CYP1A1 promoter and 5'-flanking sequences with three xenobiotic responsive elements (XREs) fused to the luciferase reporter gene. The enzyme luciferase is produced in the presence of compounds that bind the XREs, and can be detected by a simple assay that measures relative light units with a luminometer. Method 4425, used by Columbia Analytical Services (CAS), has gained acceptance as a rapid and inexpensive approach for screening solvent extracts of environmental samples of soil, sediment, tissue, and water to detect compounds that activate the AhR. Investigations in the U. S. and Japan comparing the results of 4425 and standard high-resolution GC/MS (HRGC/HRMS) will be reported here. The purpose of making these comparisons is to determine if risk assessments for large dioxin sites both before and after remediation

  8. Experimental test results from an environmental protection agency test method for determination of vapor suppressant effectiveness

    NASA Astrophysics Data System (ADS)

    Tock, Richard W.; Ahern, Daniel W.

    2005-04-01

    The results obtained from laboratory experiments conducted using Environmental Protection Agency (EPA) subpart WWWW of 40 Code of Federal Regulations (CFR) part 63 (1)-test method are discussed in this article. The original test method was developed to measure the effectiveness of wax suppressants used to reduce hazardous air pollutant (HAP) emissions from unsaturated polyester (UP)/vinyl ester resins. Wax additions of ˜1.5% by weight to commercial UP resins suppress HAP emissions through the formation of surface barrier films. However, the tests performed in this study included the use of limestone and an adjunct, organic fiber reinforcement, rather than the wax. The addition of either commercial product to the UP formulations tested in this study was also shown to reduce HAP emissions. Suppression was a combination of absorption and an increased diffusion path barrier for the volatile organic carbon (VOC) components. Based on the limited data obtained, it was shown that the oil absorption characteristics of the two adjunct products could be used to estimate the expected level of vapor suppression for a specific resin formulation. Values reported in the literature for the oil adsorption characteristics of the adjunct limestone and the commercial biomass fiber were used in the laboratory tests. Although the oil adsorption characteristic of any ingredient added to a base resin formulation is indicative of its potential for emissions reduction, the EPA test protocol is still required to be performed for validation. Such screening tests will always be needed due to the variability associated with commercial UP resins and the evolution of customized UP/fiberglass composite formulations developed by custom molding shops.

  14. The agencies method for coalition formation in experimental games

    PubMed Central

    Nash, John F.; Nagel, Rosemarie; Ockenfels, Axel; Selten, Reinhard

    2012-01-01

    In society, power is often transferred to another person or group. A previous work studied the evolution of cooperation among robot players through a coalition formation game with a non-cooperative procedure of acceptance of an agency of another player. Motivated by this previous work, we conduct a laboratory experiment on finitely repeated three-person coalition formation games. Human players with different strength according to the coalition payoffs can accept a transfer of power to another player, the agent, who then distributes the coalition payoffs. We find that the agencies method for coalition formation is quite successful in promoting efficiency. However, the agent faces a tension between short-term incentives of not equally distributing the coalition payoff and the long-term concern to keep cooperation going. In a given round, the strong player in our experiment often resolves this tension approximately in line with the Shapley value and the nucleolus. Yet aggregated over all rounds, the payoff differences between players are rather small, and the equal division of payoffs predicts about 80% of all groups best. One reason is that the voting procedure appears to induce a balance of power, independent of the individual player's strength: Selfish subjects tend to be voted out of their agency and are further disciplined by reciprocal behaviors.

    Haloacetic acids (HAAs), which are formed during the disinfection of drinking waters with chlorine, are regulated by the US Environmental Protection Agency (EPA) under the Stage 1 Disinfectant/Disinfection Byproducts (D/DBP) Rule. Recently, three studies have been reported indicating that low concentrations of HAAs can also be formed during disinfection with chloramines. Methods currently approved for compliance monitoring under the Stage 1 Rule arrest the chlorine-mediated formation of HAAs by adding ammonium chloride, which forms chloramines. Studies were undertaken using an in-process water that favored the formation of HAAs with moderate total organic carbon concentration and high levels of chlorine to investigate the potential formation of HAAs under sample storage conditions. The ammonium chloride-quenched sample did form a small amount of HAAs, but total formation over a period equal to the 14-day sample storage time was less than 2 microg/l, whereas the unquenched samples increased 41 microg/l during the same period. Pour plate studies indicated that chlorinated drinking waters quenched with ammonium chloride are protected from microbial growth, which is an important additional advantage to this preservation scheme. The presence of a combined chlorine residual should prevent microbial degradation of HAAs in samples. These studies support the preservation protocols and the sample storage times promulgated for compliance monitoring under the Stage 1 D/DBP Rule. PMID:14769409

    1983-05-01

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

    This document announces the conclusions of the EPA evaluation of the P.A.S.S. Kit device under the provisions of Section 511 of the Motor Vehicle Information and Cost Savings Act. The evaluation of the P.A.S.S. Kit device was conducted upon receiving an application for evaluation by the marketer. The P.A.S.S. Kit device is an intake manifold vacuum switch that is designed to disengage the air conditioning compressor during periods of high power demand. The device is claimed to eliminate the load of air conditioning compressor when accelerating and thereby improve fuel economy and performance. EPA fully considered all of the information submitted by the applicant. The evaluation of the P.A.S.S. Kit device was based on that information and the results of the EPA confirmatory testing of a similar device. The overall conclusion is that P.A.S.S. Kit should recover part of the emissions and fuel economy penalty incurred by using the air conditioner of some vehicles.

    Method TO-15 is an addition to the EPA Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air and consists of guidance for the sampling and analysis of volatile organic compounds (VOCs) in air. The method has undergone an initial review by the EPA and has been placed on the AMTIC bulletin board maintained by EPA`s Office of Air Quality Planning and Standards (OAQPS) for further comments before final review and formal acceptance as a new method. The method is a companion method to the previously published TO-14 method entitled, `Determination of Volatile Organic Compounds (VOCs) in Ambient Air Using SUMMA(TM) Polished Canister Sampling and Gas Chromatographic (GC) Analysis`. TO-15 differs from TO-14 in the following ways: (1) the water management system consists of the use of a small sample volume or a multisorbent/dry purge technique or both to dry the air sample; (2) the more extensive set of compounds given in Title III of the Clean Air Act Amemdments (CAAA) of 1990 constitutes the target list; (3) GC/MS techniques are recommended as the only means to identify and quantify target compounds; (4) method performance criteria are specified for acceptance of data, thereby allowing the use of alternate but equivalent sampling and analytical instrumentation; and (5) enhanced provisions for quality control are included.

    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

    PubMed

    1982-02-25

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

    2006-11-15

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

    SciTech Connect

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

    1989-01-01

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

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

    Zamecnik, J.R.

    1997-11-01

    The offgas system of the Am/Cm pilot melter at TNX was characterized by measuring the particulate evolution using a cascade impactor and EPA Method 29. This sampling work was performed by John Harden of the Clemson Environmental Technologies Laboratory, under SCUREF Task SC0056. Elemental analyses were performed by the SRTC Mobile Laboratory.Operation of the Am/Cm melter with B2000 frit has resulted in deposition of PbO and boron compounds in the offgas system that has contributed to pluggage of the High Efficiency Mist Eliminator (HEME). Sampling of the offgas system was performed to quantify the amount of particulate in the offgas system under several sets of conditions. Particulate concentration and particle size distribution were measured just downstream of the melter pressure control air addition port and at the HEME inlet. At both locations, the particulate was measured with and without steam to the film cooler while the melter was idled at about 1450 degrees Celsius. Additional determinations were made at the melter location during feeding and during idling at 1150 degrees Celsius rather than 1450 degrees Celsius (both with no steam to the film cooler). Deposition of particulates upstream of the melter sample point may have, and most likely did occur in each run, so the particulate concentrations measured do no necessarily reflect the total particulate emission at the melt surface. However, the data may be used in a relative sense to judge the system performance.

    A series of demonstration tests of the American Combustion, Inc., Thermal Destruction System was performed under the SITE program. This oxygen-enhanced combustion system was retrofit to the rotary-kiln incinerator at EPA's Combustion Research Facility. The system's performance was tested firing contaminated soil from the Stringfellow Superfund Site, both alone and mixed with a coal tar waste (KO87). Comparative performance with conventional incinerator operation was also tested. Compliance with the incinerator performance standards of 99.99% principal organic hazardous constituents (POHC) destruction and removal efficiency and particulate emissions of less than 180 mg/dscm at 7% O2 was measured for all tests. The Pyretron system was capable of in-compliance performance at double the mixed waste feedrate and at a 60% increase in batch waste charge mass than possible with conventional incineration. Scrubber blowdown and kiln ash contained no detectable levels of any of the POHCs chosen.

  15. Standardization of enterococci density estimates by EPA qPCR methods and comparison of beach action value exceedances in river waters with culture methods.

    Haugland, Richard A; Siefring, Shawn D; Varma, Manju; Dufour, Alfred P; Brenner, Kristen P; Wade, Timothy J; Sams, Elizabeth; Cochran, Stacey; Braun, Steve; Sivaganensan, Mano

    2014-10-01

    The U.S. EPA has published recommendations for calibrator cell equivalent (CCE) densities of enterococci in recreational waters determined by a qPCR method in its 2012 recreational water quality criteria (RWQC). The CCE quantification unit stems from the calibration model used to estimate enterococci densities in recreational beach waters in the EPA National Epidemiological and Environmental Assessment of Recreational (NEEAR) Water Study and directly informed the derivation of the RWQC recommendations. Recent studies have demonstrated that CCE estimates from the method can vary when using different cultured Enterococcus cell preparations in calibrator samples. These differences have been attributed to differences in the quantities of targeted gene copies (target sequences) that are recovered per nominal calibrator cell by DNA extraction. Standardization of results from the calibration model will require the estimation of target sequence recoveries from the calibrator and water samples. In addition, comparisons of water sample results with the RWQC values will require a knowledge of target sequence recoveries from the NEEAR study calibrator samples. In this study recoveries of target sequences and the mean target sequence/cell ratio for the NEEAR study calibrator samples were retrospectively estimated with a corroborated standard curve. A modification of the calibration model was then used to estimate enterococci target sequence quantities in water samples from eight midwestern U.S. rivers. CCE estimates were obtained by dividing these target sequence quantities by the mean NEEAR study target sequence/cell ratio. This target sequence-based quantification approach resulted in a high degree of agreement in beach action decisions (determinations of whether bacterial fecal indicator densities are above or below RWQC-recommended values) from CCE results of the qPCR method and from culture dependent enumeration of both enterococci and Eschericia coli in the corresponding

    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.

    1975-01-01

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

  16. A review of the methods used by the US Environmental Protection Agency to assess the financial impacts of the repository regulations

    SciTech Connect

    Pflum, C.G.; Mattson, S.R.; Matthusen, A.C.

    1994-02-16

    All Federal agencies must consider the financial impacts of their regulations. When costs significantly outweigh benefits, the Office of Management and Budget can recommend that Congress not provide the funds needed to implement the regulation. Without funds, the agency is forced to either revise or retract the regulation. This has happened previously with a regulation on uranium mill tailings proposed by the US Nuclear Regulatory Commission (NRC) and it could happen again with the US Environmental Protection Agency (EPA) regulations that govern the disposal of high-level radioactive waste (HLW). The EPA (1985, 1992) claims that its regulation: ``Environmental Standards for the Management and Disposal of Spent Nuclear Fuel, High-Level and Transuranic Radioactive Waste`` (40 CFR Part 191 or standards) does not increase costs above what the US Department of Energy (DOE) would spend anyway or, at most, what the DOE would spend to comply with 10 CFR Part 60: a regulation promulgated by the NRC. This report reviews and disputes the EPA claim. In Chapter 2 a summary of the basis for the EPA claim is presented and in Chapter 3 a critique of the basis of the claim is presented. This critique finds the EPA basis unrealistic, incomplete, and misleading. According to the EPA, a repository at Yucca Mountain would easily meet 40 CFR Part 191 even without the use of special engineered barriers. Because the NRC regulation (10 CFR Part 60) requires engineered barriers, the EPA places the onus for regulatory costs on the NRC. We disagree; the EPA standards drive regulatory costs as much as NRC regulations. The EPA has the higher responsibility for setting the overall standard for safety while the NRC can only implement this standard.

  14. Near-source mobile methane emission estimates using EPA Method33a and a novel probabilistic approach as a basis for leak quantification in urban areas

    NASA Astrophysics Data System (ADS)

    Albertson, J. D.

    2015-12-01

    Methane emissions from underground pipeline leaks remain an ongoing issue in the development of accurate methane emission inventories for the natural gas supply chain. Application of mobile methods during routine street surveys would help address this issue, but there are large uncertainties in current approaches. In this paper, we describe results from a series of near-source (< 30 m) controlled methane releases where an instrumented van was used to measure methane concentrations during both fixed location sampling and during mobile traverses immediately downwind of the source. The measurements were used to evaluate the application of EPA Method 33A for estimating methane emissions downwind of a source and also to test the application of a new probabilistic approach for estimating emission rates from mobile traverse data.

    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.

The method has three main parts; the first is the sample concentration in which at least 10 L of raw surface water is filtered. The organisms and trapped debris are then eluted from the filter and centrifuged to further concentrate the sample. The second part of the method uses an immunomagnetic separation procedure where the concentrated water sample is applied to immunomagnetic beads that specifically bind to the Cryptosporidium oocysts and Giardia cysts allowing for specific removal of the parasites from the concentrated debris. These (oo)cysts are then detached from the magnetic beads by an acid dissociation procedure. The final part of the method is the immunofluorescence staining and enumeration where (oo)cysts are applied to a slide, stained, and enumerated by microscopy. Method 1623 has four listed sample concentration systems to capture Cryptosporidium oocysts and Giardia cysts in water: Envirochek filters (Pall Corporation, Ann Arbor, MI), Envirochek HV filters (Pall Corporation), Filta-Max filters (IDEXX, Westbrook, MA), or Continuous Flow Centrifugation (Haemonetics, Braintree, MA).

  1. EPA looks to change—Not grow

    NASA Astrophysics Data System (ADS)

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

    2016-01-01

    EPA Method 1615 measures enteroviruses and noroviruses present in environmental and drinking waters. This method was developed with the goal of having a standardized method for use in multiple analytical laboratories during monitoring period 3 of the Unregulated Contaminant Monitoring Rule. Herein we present the protocol for extraction of viral ribonucleic acid (RNA) from water sample concentrates and for quantitatively measuring enterovirus and norovirus concentrations using reverse transcription-quantitative PCR (RT-qPCR). Virus concentrations for the molecular assay are calculated in terms of genomic copies of viral RNA per liter based upon a standard curve. The method uses a number of quality controls to increase data quality and to reduce interlaboratory and intralaboratory variation. The method has been evaluated by examining virus recovery from ground and reagent grade waters seeded with poliovirus type 3 and murine norovirus as a surrogate for human noroviruses. Mean poliovirus recoveries were 20% in groundwaters and 44% in reagent grade water. Mean murine norovirus recoveries with the RT-qPCR assay were 30% in groundwaters and 4% in reagent grade water.

  1. EPA Method 1615. Measurement of Enterovirus and Norovirus Occurrence in Water by Culture and RT-qPCR. I. Collection of Virus Samples

    Fout, G. Shay; Cashdollar, Jennifer L.; Varughese, Eunice A.; Parshionikar, Sandhya U.; Grimm, Ann C.

    2015-01-01

    EPA Method 1615 was developed with a goal of providing a standard method for measuring enteroviruses and noroviruses in environmental and drinking waters. The standardized sampling component of the method concentrates viruses that may be present in water by passage of a minimum specified volume of water through an electropositive cartridge filter. The minimum specified volumes for surface and finished/ground water are 300 L and 1,500 L, respectively. A major method limitation is the tendency for the filters to clog before meeting the sample volume requirement. Studies using two different, but equivalent, cartridge filter options showed that filter clogging was a problem with 10% of the samples with one of the filter types compared to 6% with the other filter type. Clogging tends to increase with turbidity, but cannot be predicted based on turbidity measurements only. From a cost standpoint one of the filter options is preferable over the other, but the water quality and experience with the water system to be sampled should be taken into consideration in making filter selections.

  3. Dietary reference intakes for DHA and EPA.

    PubMed

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

    2009-01-01

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

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

    PubMed

    Charnley, Susan; Engelbert, Bruce

    2005-11-01

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

  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. Modifications to United States Environmental Protection Agency methods 1622 and 1623 for detection of Cryptosporidium oocysts and Giardia cysts in water.

    PubMed

    McCuin, Randi M; Clancy, Jennifer L

    2003-01-01

    Collaborative and in-house laboratory trials were conducted to evaluate Cryptosporidium oocyst and Giardia cyst recoveries from source and finished-water samples by utilizing the Filta-Max system and U.S. Environmental Protection Agency (EPA) methods 1622 and 1623. Collaborative trials with the Filta-Max system were conducted in accordance with manufacturer protocols for sample collection and processing. The mean oocyst recovery from seeded, filtered tap water was 48.4% +/- 11.8%, while the mean cyst recovery was 57.1% +/- 10.9%. Recovery percentages from raw source water samples ranged from 19.5 to 54.5% for oocysts and from 46.7 to 70.0% for cysts. When modifications were made in the elution and concentration steps to streamline the Filta-Max procedure, the mean percentages of recovery from filtered tap water were 40.2% +/- 16.3% for oocysts and 49.4% +/- 12.3% for cysts by the modified procedures, while matrix spike oocyst recovery percentages ranged from 2.1 to 36.5% and cyst recovery percentages ranged from 22.7 to 68.3%. Blinded matrix spike samples were analyzed quarterly as part of voluntary participation in the U.S. EPA protozoan performance evaluation program. A total of 15 blind samples were analyzed by using the Filta-Max system. The mean oocyst recovery percentages was 50.2% +/- 13.8%, while the mean cyst recovery percentages was 41.2% +/- 9.9%. As part of the quality assurance objectives of methods 1622 and 1623, reagent water samples were seeded with a predetermined number of Cryptosporidium oocysts and Giardia cysts. Mean recovery percentages of 45.4% +/- 11.1% and 61.3% +/- 3.8% were obtained for Cryptosporidium oocysts and Giardia cysts, respectively. These studies demonstrated that the Filta-Max system meets the acceptance criteria described in U.S. EPA methods 1622 and 1623. PMID:12514004

  19. Developing US EPA`s environmental technology cooperation center: A new approach to Foster technology transfer partnerships

    SciTech Connect

    Burke, C.J.

    1994-12-31

    This paper presents a conceptual framework and approach for establishing the US Environmental Protections Agency`s (EPA) environmental technology cooperation center. The topic is introduced with background information on events leading to the development and implementation of the center and brief overviews of the domestic and global environmental industries. The paper assesses several US environmental technology transfer programs and identifies significant, innovative, and instructive technology transfer methods which offer constructive models for the center. This examination focuses on several modes of public-private interaction required to facilitate the transfer of US environmental technologies into the international marketplace. Specific case studies of environmental technology cooperation initiatives include: the US-Asian Environmental Partnership (AEP), the US Environmental Training Institute (US ETI) and the recent International Environmental Technology Business Action Conference, which took place in Moscow last month. This information forms a basis for defining the needs, gaps and opportunities for the technology cooperation center. Technology transfer and cooperation programs must respond to a range of changing needs and requirements in the increasingly competitive and sophisticated global economy of the 1990`s. The environmental technology cooperation center concept developed by the US EPA offers an approach for enhancing public-private sector partnerships to improve domestic industry collaborations and enhance trans-national team-building. An innovative approach by EPA, in collaboration with other agencies and the private sector, can lead to the rapid introduction of a global network of national and regional centers to foster international environmental cooperation and team-building in the years ahead.

  20. 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.

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

    SciTech Connect

    Wray, T.K.

    1996-11-01

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

  7. Methods and Sources of Data Used to Develop Selected Water-Quality Indicators for Streams and Ground Water for EPA's 2007 Report on the Environment: Science Report

    USGS Publications Warehouse

    Baker, Nancy T.; Wilson, John T.; Moran, Michael J.

    2008-01-01

    The U.S. Geological Survey (USGS) was one of numerous governmental agencies, private organizations, and the academic community that provided data and interpretations for the U.S. Environmental Protection Agency?s (USEPA) 2007 Report on the Environment: Science Report. This report documents the sources of data and methods used to develop selected water?quality indicators for the 2007 edition of the report compiled by USEPA. Stream and ground?water?quality data collected nationally in a consistent manner as part of the USGS?s National Water?Quality Assessment Program (NAWQA) were provided for several water?quality indicators, including Nitrogen and Phosphorus in Streams in Agricultural Watersheds; Pesticides in Streams in Agricultural Watersheds; and Nitrate and Pesticides in Shallow Ground Water in Agricultural Watersheds. In addition, the USGS provided nitrate (nitrate plus nitrite) and phosphorus riverine load estimates calculated from water?quality and streamflow data collected as part of its National Stream Water Quality Accounting Network (NASQAN) and its Federal?State Cooperative Program for the Nitrogen and Phosphorus Discharge from Large Rivers indicator.

  11. EPA's monitoring program at Love Canal 1980.

    PubMed

    Hauser, T R; Bromberg, S M

    1982-09-01

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

  11. EPA`s integrated nitrogen oxides strategy

    SciTech Connect

    Grano, D.H.

    1997-12-31

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

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

    SciTech Connect

    Hill, M.

    1996-03-01

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

  7. Modeling a point-source release of 1,1,1-trichloroethane using EPA`s SCREEN model

    SciTech Connect

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

    1994-12-31

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

    A mixed-methods design was used to assess the current capacity of human service agencies to provide services in a major disaster, identify challenges and successful strategies for providing those services, and formulate specific recommendations for government planners and the nonprofit sector to promote the integration of human service agencies into emergency preparedness and response. A web-based survey was completed by 188 unique human service agencies, 31 semistructured interviews were conducted with human service agency and government leaders from southeastern Pennsylvania and the mid-Atlantic region, and a collaborative planning meeting was held to review the findings and develop systems-based recommendations. Survey results indicated that human service agencies serve the most vulnerable communities during disasters and would welcome integration into preparedness and response plans, but they currently face challenges that include a lack of real-time communication and opportunities for collaborative planning with government partners. Interview findings were grouped according to 5 themes that emerged: capacity, coordination, communication, training, and leadership. This study identified recommendations to assist human service agencies, local health departments, and emergency management agencies as they work to ensure that needed human services are available during disasters, despite the resource challenges that most agencies face.

    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

    Knowing the metal extraction capacity of a digestion method is crucial for a better environmental interpretation of metal concentrations determined in sediments. One of the main problems at the present is the lack of harmonization of information obtained by two of the most popular sediment partial digestion methods: ISO 11466.3 (aqua regia) and EPA 3050B (HNO₃--H₂O₂--HCl). In the present work, the amount of Cu, Ni and Pb leached by using both methods was compared with the total content of those elements in marine sediments collected, as an example, from the Cienfuegos Bay, Cuba. Similar amounts of Cu were extracted by both methods; while leaching of Ni and Pb were different. Generally, the EPA method extracted more Ni than the ISO method. In contrast, Pb was extracted in a larger amount by the ISO method. Some explanations are given for the observed results. X-ray Diffraction, X-ray Fluorescence, Particle Induced X-ray Emission Spectrometry and Energy Dispersive X-ray coupled to Scanning Electron Microscopy were employed for this purpose. On the other hand, none of the methods studied extracted simultaneously the fraction of all the metals, probably provided by human activity (Theoretical Anthropogenic Fraction) in both sediments studied. The use of ISO 11466.3 or EPA 3050B is recommended since the analytical performance parameters of both, in combination with Flame Atomic Absorption Spectrometry, are adequate. For a better environmental interpretation of the analytical results, information on the extraction efficiency of the selected method for specific elements and sediments under study should also be provided, together with the determined concentrations.

  19. 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.

    2010-02-26

    Washington River Protection Solutions, LLC (WRPS) has faced significant project management challenges in managing Davis-Bacon construction work that meets contractually required small business goals. The unique challenge is to provide contracting opportunities to multiple small business constructioin subcontractors while performing high hazard work in a safe and productive manner. Previous to the WRPS contract, construction work at the Hanford Tank Farms was contracted to large companies, while current Department of Energy (DOE) Contracts typically emphasize small business awards. As an integral part of Nuclear Project Management at Hanford Tank Farms, construction involves removal of old equipment and structures and installation of new infrastructure to support waste retrieval and waste feed delivery to the Waste Treatment Plant. Utilizing the optimum construction approach ensures that the contractors responsible for this work are successful in meeting safety, quality, cost and schedule objectives while working in a very hazardous environment. This paper descirbes the successful transition from a traditional project delivery method that utilized a large business general contractor and subcontractors to a new project construction management model that is more oriented to small businesses. Construction has selected the Agency Construction Management Method (John E Schaufelberger, Len Holm, "Management of Construction Projects, A Constructor's Perspective", University of Washington, Prentice Hall 2002). This method was implemented in the first quarter of Fiscal Year 2009 (FY2009), where Construction Management is performed by substantially home office resources from the URS Northwest Office in Richland, Washington. The Agency Method has allowed WRPS to provide proven Construction Managers and Field Leads to mentor and direct small business contractors, thus providing expertise and assurance of a successful project.

    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.

  2. 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.

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

    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.

    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.”

  12. Cryptosporidium and giardia recoveries in natural waters by using environmental protection agency method 1623.

    2002-12-01

    Relatively few studies have examined recoveries from source waters by using Environmental Protection Agency method 1623 with organism spike doses that are environmentally realistic and at turbidity levels commonly found in surface waters. In this study, we evaluated the filtration capacities and recovery efficiencies of the Gelman Envirochek (standard filter) and the Gelman Envirochek high-volume (HV) sampling capsules under environmental conditions. We also examined the performance of method 1623 under ambient conditions with matrix spike experiments using 10 organisms/liter. Under turbid conditions, the HV capsule filtered approximately twice the volume filtered by the standard filter, but neither could filter 10 liters without clogging. In low-turbidity waters, oocyst, but not cyst, recoveries were significantly higher when the HV capsule was used. In turbid waters, organism recoveries were lower than those in nonturbid waters and were not significantly different for the different filters. When the HV capsule was used, Cryptosporidium recoveries ranged from 36 to 75%, and Giardia recoveries ranged from 0.5 to 53%. For both organisms, recoveries varied significantly by site. Turbidity could explain variation in Giardia recoveries (r(2) = 0.80) but not variation in Cryptosporidium recoveries (r(2) = 0.16). The inconsistent recoveries across sites suggested that the background matrix of the ambient water affected recovery by method 1623. A control sample collected at the height of the winter rainy season detected one organism, highlighting the difficulty of using this method to accurately measure pathogen abundance under natural conditions. Our findings support the use of the HV filter under field conditions but suggest that designing a cost-effective and statistically valid monitoring program to evaluate sources and loads of protozoan pathogens may be difficult.

    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.

    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

    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.

  1. Determination of Methyl tert-Butyl Ether and tert-Butyl Alcohol in Water by Solid-Phase Microextraction/Head Space Analysis in Comparison to EPA Method 5030/8260B

    Oh, Keun-Chan; Stringfellow, William T.

    2003-10-02

    Methyl tert-butyl ether (MTBE) is now one of the most common groundwater contaminants in the United States. Groundwater contaminated with MTBE is also likely to be contaminated with tert-butyl alcohol (TBA), because TBA is a component of commercial grade MTBE, TBA can also be used as a fuel oxygenate, and TBA is a biodegradation product of MTBE. In California, MTBE is subject to reporting at concentrations greater than 3 {micro}g/L. TBA is classified as a ''contaminant of current interest'' and has a drinking water action level of 12 {micro}g/L. In this paper, we describe the development and optimization of a simple, automated solid phase microextraction (SPME) method for the analysis of MTBE and TBA in water and demonstrate the applicability of this method for monitoring MTBE and TBA contamination in groundwater, drinking water, and surface water. In this method, the headspace (HS) of a water sample is extracted with a carboxen/polydimethylsiloxane SPME fiber, the MTBE and TBA are desorbed into a gas chromatograph (GC), and detected using mass spectrometry (MS). The method is optimized for the routine analysis of MTBE and TBA with a level of quantitation of 0.3 {micro}g/L and 4 {micro}g/L, respectively, in water. MTBE quantitation was linear for over two orders of concentration (0.3 {micro}g/L -80 {micro}g/L). TBA was found to be linear within the range of 4 {micro}g/L-7,900 {micro}g/L. The lower level of detection for MTBE is 0.03 {micro}g/L using this method. This SPME method using headspace extraction was found to be advantageous over SPME methods requiring immersion of the fiber into the water samples, because it prolonged the life of the fiber by up to 400 sample analyses. This is the first time headspace extraction SPME has been shown to be applicable to the measurement of both MTBE and TBA at concentrations below regulatory action levels. This method was compared with the certified EPA Method 5030/8260B (purge-and-trap/GC/MS) using split samples from

    In September 1997, the US Department of Energy (DOE) and US Environmental Protection Agency (EPA) co-sponsored a demonstration of several multimetal continuous emission monitors (CEMs). The demonstration, performed at the EPA National Risk Management Research Laboratory, Air Pollution Prevention and Control Division`s combustion laboratory in Research Triangle Park, NC, involved the side-by-side testing of seven multimetal CEMs at various stages of commercialization. A series of tests were performed to compare results from the multimetal CEMs to Method 0060, the EPA reference method (RM) for metals emissions measurements, using the relative accuracy test audit (RATA) protocol. The EPA operated the test facility and performed the RM sampling, and each multimetal CEM was operated by the instrument`s respective developer. To accomplish these tests, an aqueous solution of six toxic metals (arsenic, beryllium, cadmium, chromium, lead, and mercury), along with flyash from a coal-fired utility boiler, was injected into the afterburner of the EPAs rotary kiln incinerator simulator facility to generate a combustor flue gas with realistic post-flue gas cleaning system particulate loadings and target metals concentrations of approximately 15 and 75 {micro}g/m{sup 3}, which constituted the low and high concentration test conditions. The multimetal CEMs that participated in the test included two laser-induced breakdown spectroscopy (LIBS) systems, two inductively coupled plasma (ICP) systems, a spark-induced breakdown spectroscopy (SIBS) system, a hazardous element sampling train with X-ray fluorescence (HEST/XRF), and a microwave plasma system. Ten RM-CEM sample pairs were taken at both the low and high concentration test conditions, and the relative accuracies of the multimetal CEMs were calculated. This test provided performance data that will be used to assess the current state of the art in multimetal CEMs.
