  4. Clean Air Act: Senate mulls revision bill

    SciTech Connect

    Fairley, P.

    1995-12-13

    Senator Lauch Faircloth (R., NC) has circulated a draft summary of possible revisions of the Clean Air Act (CAA). Chemical industry sources say the proposal would provide some regulatory relief but fear that supporting Faircloth could jeopardize their relationship with EPA. Faircloth`s proposal addresses various controversial aspect of CAA`s Title V permit program including the monitoring and permit modification provisions. The proposal would also define a facility`s {open_quotes}potential to emit,{close_quotes} upon which Title V permits are based. In the past year EPA has substantially revised its Title V program to address complaints from industry, the states, and Congress that the monitoring and modification provisions were too burdensome.

    Pahl, D.; Hunt, W.; Evans, G.

    1992-01-01

    The Clean Air Act Amendments of 1990 have expanded the requirements for trace metal and air toxics information in urban areas and added new requirements for this information in rural areas and ecosystems. Specific provisions germane to trace metals and other air toxics compounds are found in Title III, Section 112 and in Title IX, Section 901. In response to these provisions, the United States Environmental Protection Agency (EPA) plans to conduct research in atmospheric monitoring networks in urban areas, in the Great Lakes watershed, and in regional components of a national Clean Air Act status and trends network.

  6. Asthma, sulfur dioxide, and the Clean Air Act

    SciTech Connect

    Boushey, H.

    1982-02-01

    Laboratory findings on the effects of sulfur dioxide in patients with asthma are related to theories about the mechanisms of bronchial hyperreactivity, an abnormality that may be fundamental to the pathogenesis of asthma and then to questions of national policy on air quality. Work has shown that people with asthma are abnormally sensitive to inhalation of sulfur dioxide and that bronchospasm may develop if they pursue activities that require light exercise while breathing air containing a level of sulfur dioxide permitted by current ambient air-quality standards. The provisions of the Clean Air Act of 1970 require that sensitive groups in the population be protected against adverse health effects, and our data therefore indicate the need for a short-term standard for sulfur dioxide.

  14. Optimizing electric utility air toxics compliance with other titles of the Clean Air Act

    SciTech Connect

    Loeb, A.P.; South, D.W.

    1993-12-31

    This paper provides an overview of regulatory issues under Title III of the Clean Air Act Amendments that could affect electric utilities. Title III contains provisions relating to hazardous air pollutants (HAPs) and provides special treatment for electric utilities. Generally, this discussion documents that if utility toxic emissions are regulated, one of the chief difficulties confronting utilities will be the lack of coordination between Title III and other titles of the Act. The paper concludes that if the US Environmental Protection Agency (EPA) determines that regulation of utility HAPs is warranted under Title III, savings can be realized from flexible compliance treatment.

  9. Highlights of the Clean Air Act Amendments of 1990

    SciTech Connect

    Lee, B.

    1991-01-01

    The amendments to the Clean Air Act provide for operating permits for stationary sources of pollution, marking a change that is comparable to federal water pollution regulations. The bill addresses acid rain emissions and will phase out production of chemicals contributing to depletion of the stratospheric ozone layer. A major new concept incorporated into the emission limits established by law is a system of tradeable emissions credits. If a facility reduces emissions below the standard or ahead of the timetable set by law, emissions credits are earned that can be applied to future emissions or sold to another facility. The bill also provides strict deadlines for the EPA to meet in promulgating the regulations. These deadlines will seriously strain the personnel and financial resources of the agency. Perhaps the most significant of the miscellaneous items in the law is a provision for extended unemployment benefits under the Job Training Partnership Act for workers who lose their jobs because of the law's provisions. However, this is contingent on the displaced workers' seeking job retraining.

  18. Some impacts of the 1990 Clean Air Act and state clean-air regulations on the fertilizer industry

    1992-12-01

    The Clean Air Act amendments of 1990 will intensify national efforts to reduce air pollution. They will have major impacts an governmental agencies and on industrial and commercial facilities throughout the country. As with other industries, it is essential for fertilizer dealers and producers to understand how these changes to the Clean Air Act can significantly change the way they do business. This paper is proffered as an overview of ways in which the 1990 amendments to the Clean Air Act may impact the fertilizer industry. The nonattainment, toxics, and permit provisions of the amended act will be three areas of particular concern to the fertilizer industry. Implementation of the new regulatory requirements of this legislation promises to be a long and onerous process for all concerned. However, it appears that state and local regulations may have a much more profound impact on the fertilizer industry than the new Clean Air Act.

  1. BACT analysis under the Clean Air Act's PCD program

    SciTech Connect

    Simms, P.; Walke, J.

    2006-11-15

    Before a company may build a new major industrial source of air pollution, or make modifications to an existing major source in the USA it must apply for and receive a Clean Air Act (CAA) Prevention of Significant Deterioration (PSD) permit. State environmental agencies typically issue such permits, either under state law or by exercising delegated authority to implement the federal PSD program. To fully comply with the CAA, the emissions limits identified as BACT must incorporate consideration of more than just add-on emissions control technology, they must also reflect appropriate considerations of fuel quality (e.g. low-sulfur coal) and process changes (e.g. advanced combustion techniques) as a means of controlling emissions, and must consider the other environmental and public welfare benefits of the identified emissions control options. Several states including New Mexico and Illinois have already determined that innovated technologies, such as Integrated Gasification Combined Cycle (IGCC), must be considered in connection with the BACT analysis for new coal-fired power plants. Even the notion that BACT is categorically limited in scope to the general type of facility proposed is contrary to EPA precedent. For example, the Environmental Appeals Board (EAB) has explained that permitting authorities retain the discretion under the definition of BACT to require dramatically different facility designs (e.g. a natural gas plant instead of a coal-fired power plant). The best advice for any permit applicant is to include in the BACT analysis a careful and honest examination of better performing alternative processes and/or innovative combustion techniques and to aggressively pursue such options wherever feasible. 17 refs.

    Measurement methods for the 189 Hazardous Air Pollutants (HAPs) designated in Title III of the 1990 Clean Air Act Amendments are either identified or suggested for all but 10 of the compounds. An extensive list of chemical and physical properties are provided for all compounds. Suggestions for methods development of compounds with no written references are based on the similarity of these chemical and physical properties to other of the HAPs. For 126 of the HAPs, established and documented methods were found; for 53 other HAPs, methods were identified having need for further development; and for 10 HAPs, either no methods or methods requiring extensive development were found. The primary recommendation of the study is that method development be focussed on the 53 HAPs for which additional development is expected to result in reliable methods.

  4. The Clean Air Act impacts on rail coal

    SciTech Connect

    Sharp, R.G. )

    1991-03-01

    These factors are examined in this article. In November 1990, President Bush signed the Clean Air Act amendments of 1990 into law. Title IV, concerning acid rain control, calls for a two-phase reduction in power plant sulfur-dioxide emissions, culminating in a nationwide cap after the year 2000. A large part of this reduction will be obtained through substituting low-sulfur coals for the higher-sulfur fuels now used. Most commentators have characterized this legislation as a boon for low-sulfur coal producers and the railroads serving them. If, as projected, up to one-eighth of existing coal-burning plants shift to more distant suppliers, a surge in rail traffic would ensue. Whether this traffic originates at eastern or western mines, rail carriers would obtain longer hauls and greater coal volumes. We have examined the rail transport implications of the amendments and found that the potential rail benefits may be exaggerated. Although traffic volume will grow, margins on some new traffic are likely to be eroded by continued rate competition and reduced productivity. To satisfy coal transport needs in the 1990s, factors that challenge rail productivity must be recognized and resolved.

  5. Air toxics provisions of the Clean Air Act: Potential impacts on energy

    Hootman, H.A.; Vernet, J.E.

    1991-11-01

    This report provides an overview of the provisions of the Clean Air Act and its Amendments of 1990 that identify hazardous air pollutant (HAP) emissions and addresses their regulation by the US Environmental Protection Agency (EPA). It defines the major energy sector sources of these HAPs that would be affected by the regulations. Attention is focused on regulations that would cover coke oven emissions; chromium emission from industrial cooling towers and the electroplating process; HAP emissions from tank vessels, asbestos-related activities, organic solvent use, and ethylene oxide sterilization; and emissions of air toxics from municipal waste combustors. The possible implications of Title III regulations for the coal, natural gas, petroleum, uranium, and electric utility industries are examined. The report discusses five major databases of HAP emissions: (1) TRI (EPA`s Toxic Release Inventory); (2) PISCES (Power Plant Integrated Systems: Chemical Emissions Studies developed by the Electric Power Research Institute); (3) 1985 Emissions Inventory on volatile organic compounds (used for the National Acid Precipitation Assessment Program); (4) Particulate Matter Species Manual (EPA); and (5) Toxics Emission Inventory (National Aeronautics and Space Administration). It also offers information on emission control technologies for municipal waste combustors.

  16. Rationing health protection: a proposal to exempt nuisance dust from US Clean Air Act regulations.

    Centner, Terence J; Colson, Gregory

    2013-03-15

    The US House of Representative has passed a bill called the "Farm Dust Regulation Prevention Act" (Dust Act) that would exempt most types of particulate matter (PM) in rural areas from the air quality controls of the US Clean Air Act. The Dust Act would markedly change the country's air quality standards. An examination of the proposed provisions shows that they would exempt non-combustion PM pollutants from mining, smelting, petroleum production, and power generation from existing air quality standards. Persons downwind from pollutants generated in rural areas could be exposed to concentrations of carcinogenic heavy metals, asbestos, and benzene known to adversely affect their health and ecological resources. Existing federal air quality standards based on science would be replaced by a flexible standard that rations health protection. PMID:23376304

    A repository of 59 organic compounds has been established by the U.S. Environmental Protection Agency (EPA) for use as gas standards in performance audits during field validation of emission concentrations from stationary sources. These compounds are listed in Title III of the 1990 Clean Air Act Amendment. The compounds are prepared in compressed gas cylinders and recyclable aluminum containers. Three concentration ranges were selected: low (20 to 200 ppb), mid-level (0.5 to 5 ppm), and high (5 to 50 ppm). The recyclable aluminum containers were only prepared in the low range, and pressures were generally below 400 psig. The compressed gas cylinders contained pressures up to 2000 psig. In this program to ensure that the concentration of each gas standard had not changed, each standard was analyzed periodically for stability. The gas mixtures were analyzed by the manufacturer before shipment. They were then analyzed upon receipt, and reanalyzed periodically to determine any change in concentration. The stability data obtained to date indicates that many compounds are stable in the compressed gas cylinders; however, some of the compounds in the recyclable containers are not stable.

  19. Trials and tribulations implementing the Clean Air Act Title V in fourteen air districts

    SciTech Connect

    Moore, C.

    1998-12-31

    Santa Fe pacific Pipeline Partners, L.P. (SFPP) is a refined petroleum pipeline operating in six states in the western United States. Sixteen terminals are subject to the Title V permit to operate requirements. There are many obstacles to overcome, not only when preparing applications for Title V operating permits, but in the implementation phase of the project as well. Each Air District has its own set of rules and regulations that must be adhered to in preparing the application. For example, some districts required the insignificant sources to be documented and included in compliance plans and some do not. The format required for the application varies from stringent forms that must be completed to no forms at all. In preparing the Title V application for SFPP, the author quickly realized if this confusion was transferred to the implementation phase, compliance would be a failure. Therefore, early on the environmental manager instituted a training program. Beginning with a pilot program in one district the author began training managers and supervisors. This program quickly was expanded to include senior vice presidents and technicians. This training session was a one hour of general overview to visually describe how the Title V process would affect the facilities. As a result of this training, virtually every employee became familiar with how the Title V program was affecting the facilities. Engineering and Customer Service is instructed to notify the manager of any and every new project so it could undergo a review to determine if it affected a Title V facility. The field acts as a check of the system. Any change or modification at any facility is immediately under scrutiny for Title V implications. Another obstacle to overcome is to help the facility deal with something that is new and basically a different way of operating.

    1992-03-01

    In response to numerous requests for information related to odor thresholds, this document was prepared by the Air Risk Information Support Center in its role in providing technical assistance to State and Local government agencies on risk assessment of air pollutants. A discussion of basic concepts related to olfactory function and the measurement of odor thresholds is presented. A detailed discussion of criteria which are used to evaluate the quality of published odor threshold values is provided. The use of odor threshold information in risk assessment is discussed. The results of a literature search and review of odor threshold information for the chemicals listed as hazardous air pollutants in the Clean Air Act amendments of 1990 is presented. The published odor threshold values are critically evaluated based on the criteria discussed and the values of acceptable quality are used to determine a geometric mean or best estimate.

  3. Consumer response to the New York City Smoke-Free Air Act.

    1999-01-01

    The objective of this study was to assess consumer response to the New York City Smoke-Free Air Act. The overwhelming majority of respondents reported they were largely unaffected by the law or dined out more frequently since the law took effect; however, there was a small percentage of consumers that reported dining out less frequently. There were few reports of consumers who stopped dining out altogether or left or entered the city with the specific purpose of dining in a place that suited their smoking preference. The New York City Smoke-Free Air Act appears to have had little impact on the dining out patterns of consumers. PMID:10345510

    The objective of this study was to assess the economic impact of the Erie County, New York, Clean Air Act on the restaurant industry by examining restaurant employment and payroll statistics. Monthly county-specific data were compared between 1996 (before the law), 1997 (after phase 1, which required 80% of indoor restaurant seating to be smoke-free), and 1998 (after phase 2 which prohibited smoking in 100% of indoor restaurant seating). Erie County's Clean Air Act had no adverse economic impact on its restaurant industry. PMID:18019963

  10. Triassic marine reptiles gave birth to live young.

    PubMed

    Cheng, Yen-Nien; Wu, Xiao-Chun; Ji, Qiang

    2004-11-18

    Sauropterygians form the largest and most diverse group of ancient marine reptiles that lived throughout nearly the entire Mesozoic era (from 250 to 65 million years ago). Although thousands of specimens of this group have been collected around the world since the description of the first plesiosaur in 1821 (ref. 3), no direct evidence has been found to determine whether any sauropterygians came on shore to lay eggs (oviparity) like sea turtles, or gave birth in the water to live young (viviparity) as ichthyosaurs and mosasauroids (marine lizards) did. Viviparity has been proposed for plesiosaur, pachypleurosaur and nothosaur sauropterygians, but until now no concrete evidence has been advanced. Here we report two gravid specimens of Keichousaurus hui Young from the Middle Triassic of China. These exquisitely preserved specimens not only provide the first unequivocal evidence of reproductive mode and sexual dimorphism in sauropterygians, but also indicate that viviparity could have been expedited by the evolution of a movable pelvis in pachypleurosaurs. By extension, this has implications for the reproductive pattern of other sauropterygians and Mesozoic marine reptiles that possessed a movable pelvis. PMID:15549103

    This report examines Some issues that would I affect the refining industry if the requirements for hazardous air pollutants set out in Title III of the Clean Air Act Amendments were to impede the market entrance of oxygenated fuels, as me; required by Title II. It describes the mandate for reformulated gasoline; considers gasoline characteristics in light of component shifts in refining; examines the supply of, demand for, and cost of various feedstocks and blendstocks; and identifies the emissions and atmospheric impacts that might result from the production and use of reformulated gasoline. Attention is focused on methanol and MTBE, two potential blendstocks that are also hazardous air pollutants, and on maximum achievable control technology standards, which might be applied to the stationary sources that produce them.

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

    SciTech Connect

    Paul, P.J.

    1997-12-31

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

  19. The politics of markets: The acid rain control policy in the 1990 Clean Air Act amendments

    SciTech Connect

    Kete, N.

    1993-01-01

    This thesis is a review and critique of the development of the acid rain control policy codified as Title IV of the Clean Air Act. The amendments include provisions to address acid rain-air pollution that has been transformed and transported over long distances. Title IV also embodies the first large scale adoption of market principles and economic incentives in the cause of environmental protection. The acid rain control amendments are being hailed as a break with past environmental protection practice and are being offered as a model for further regulatory reform. The thesis looks at the roots of the acid rain policy and considers the set of legal, social, and economic relations embedded in the policy which define the nature of its legal controls over pollution and its inverse, environmental quality. It explores whether the creation of the emissions allowance trading system changes the social relationships that prevailed under the pre-amended Clean Air Act. It responds to and rebuts the concerns of some critics that the policy represents an alienation of the public's right to clean air. A review of the acid rain policymaking process provides a recent and concrete example of the two central concerns inherent in public policy: the making of decisions that establish institutional arrangements, or structures, that both constrain and liberate individual action at the operational level; and the search for the boundary between autonomous behavior and collective decision making. The policy responds to regulatory reform recommendations concerned with improving the effectiveness, accountability, and cost-effectiveness of environmental protection. As a model for future policymaking, the policy goes beyond and encompasses more than the welfare economics ideal of static economic efficiency and the [open quotes]free market environmentalism[close quotes] emphasis on private property and common law.

  18. Airborne lidar mapping of vertical ozone distributions in support of the 1990 Clean Air Act Amendments

    NASA Technical Reports Server (NTRS)

    Uthe, Edward E.; Nielsen, Norman B.; Livingston, John M.

    1992-01-01

    The 1990 Clean Air Act Amendments mandated attainment of the ozone standard established by the U.S. Environmental Protection Agency. Improved photochemical models validated by experimental data are needed to develop strategies for reducing near surface ozone concentrations downwind of urban and industrial centers. For more than 10 years, lidar has been used on large aircraft to provide unique information on ozone distributions in the atmosphere. However, compact airborne lidar systems are needed for operation on small aircraft of the type typically used on regional air quality investigations to collect data with which to develop and validate air quality models. Data presented in this paper will consist of a comparison between airborne differential absorption lidar (DIAL) and airborne in-situ ozone measurements. Also discussed are future plans to improve the airborne ultraviolet-DIAL for ozone and other gas observations and addition of a Fourier Transform Infrared (FTIR) emission spectrometer to investigate the effects of other gas species on vertical ozone distribution.

  20. Escaping the regulatory dust bowl: fugitive dust and the Clean Air Act

    SciTech Connect

    Probst, G.L.; Becker, R.E. Jr.

    1982-01-01

    The Environmental Protection Agency's (EPA's) regulatory program, as it relates to particulates, is overly complicated. In attempting to accommodate statutory language insensitive to particulate differences, after becoming aware of the varying effects of different-sized particles, EPA has developed an unworkable program. Although agricultural, recreational, transportation, and industrial activities contribute to the airborne dust (or, in the Clean Air Act vernacular, fugitive dust), this article focuses on mining activities. Surface mining inevitably stirs up considerable fugitive dust, and a description of mining activities in arid conditions, and how they fit in with a developing regulatory program, reveals a story of a national program that fails to provide for rational policy and regional flexibility. The article also recommends some regulatory and statutory solutions that could relatively easily correct EPA's fugitive dust program.

  1. Clean Air Act Title IV: Lessons learned from Phase I; getting ready for Phase II

    SciTech Connect

    Miller, M.J.

    1997-12-31

    The 1990 Clean Air Act Amendments have required significant reductions in SO{sub 2} and NO{sub x} emissions from fossil fuel-fired power plants in the US. This paper examines some of the key technical lessons learned in Phase I following retrofit of low NO{sub x} systems, FGD systems, and continuous emissions monitors. Some of the key problems encountered have been waterwall wastage as a result of low NO{sub x} burner retrofits; high LOI (carbon) ash as a result of low NO{sub x} operation; high O&M costs associated with CEMs; and the heat rate discrepancy which has arisen between CEMs and conventional heat rate calculations. As Phase II approaches, EPRI and the electric utility industry are investigating improvements in FGD systems (e.g., clear liquor scrubbing), advances in NO{sub x} control technologies, more robust CEM systems, and tools to help in the technology decision-making process.

  2. Implications of the Clean Air Act acid rain title on industrial boilers

    SciTech Connect

    Maibodi, M. )

    1991-11-01

    This paper discusses the impacts of the 1990 Clean Air Act Amendments related to acid rain controls, as they apply to industrial boilers. Emphasis is placed on explaining the Title IV provisions of the Amendments that permit nonutility sources to participate in the SO{sub 2} allowance system. The allowance system, as it pertains to industrial boiler operators, is described, and the opportunities for operators to trade and/or sell SO{sub 2} emission credits is discussed. The paper also reviews flue gas desulfurization system technologies available for industrial boiler operators who may choose to participate in the system. Furnace sorbent injection, advanced silicate process, lime spray drying, dry sorbent injection, and limestone scrubbing are described, including statements of their SO{sub 2} removing capability, commercial status, and costs. Capital costs, levelized costs and cost-effectiveness are presented for these technologies.

  3. Effects of the 1990 Clean Air Act amendments on distributions of visual impairment

    1996-02-01

    The Acid Rain Provisions (Title IV) of the 1990 Clean Air Act Amendments (1990 CAAA) focus on emission policies designed to reduce the amount of deposition of acidifying pollutants, particularly in the Northeast. The primary strategy is a significant reduction in SO{sub 2} emissions, with lesser reductions scheduled for NO{sub {times}} emissions. However, lessening of acid deposition is not the only important benefit of the emission control strategy. Decreasing SO{sup {minus}} and NO {sup {minus}} emissions will decrease atmospheric concentrations of sulfate and nitrate particles, which account for much of the visibility reduction associated with regional haze. Although one can get a qualitative sense of how visibility might improve by examining historical large-scale trends in regional emission totals and regional visibility, quantification of the expected improvement requires model simulations. One must model the spatial and temporal patterns of emissions reductions; the relevant pollutant transport, transformation, and removal processes in the atmosphere; and the changes in particulate loading. For this initial examination of the visibility improvement at Shenandoah National Park associated the the Phase I and Phase II SO{sub 2} emission reductions, we have linked emission trend projections taken from ongoing analysis of the 1990 CAAA at Argonne National Laboratory, regional transport modeling with the Advanced Statistical Trajectory Regional Air Pollution (ASTRAP) model and visual impairment modeling with the Visibility Assessment Scoping Model (VASM).

  4. Impact of Clean Air Act Regulations on Nitrogen Fate and Transport in the Neuse River Basin

    NASA Astrophysics Data System (ADS)

    Gabriel, M. C.; Knightes, C. D.; Dennis, R. L.; Cooter, E. J.

    2012-12-01

    This study investigated impacts of Clean Air Act Amendment (CAAA) NOx emissions regulations on the fate and transport of nitrogen for two watersheds in the Neuse River Basin, North Carolina, USA from 1990 to 2020. The Soil and Water Assessment Tool (SWAT) and the Community Multi-scale Air Quality (CMAQ) modeling system were used. CMAQ simulated atmospheric chemical transport and nitrogen deposition. This data was entered into SWAT which simulated watershed hydrology and water quality. Two cases were investigated: one that incorporates CAAA regulatory emissions controls in CMAQ simulation (with) and a second case that does not (without). SWAT model results forecasted a 70% decrease in inorganic nitrogen discharge from the Little River watershed and a 50% decrease for the Nahunta watershed by 2020 under the emission control (with) scenario. Denitrification and plant nitrogen uptake played important roles in nitrogen discharge from each watershed. The nitrogen discharge response time following a change in atmospheric nitrogen deposition was 4 years for the Nahunta watershed and 2 years for the Little River watershed. The longer response time for Nahunta is primarily due to a higher percentage of soybean land cover (22.5% [Nahunta]; 1.6% [Little River]). Agricultural land covers had varied nitrogen response times to changes in atmospheric deposition, particularly for soybean, hay and corn. The studied watersheds retained >80% of all nitrogen delivered by agriculture fertilization, biological fixation and atmospheric deposition.

  5. Assessing the potential visibility benefits of Clean Air Act Title IV emission reductions

    SciTech Connect

    Trexler, E.C. Jr.; Shannon, J.D.

    1995-06-01

    Assessments are made of the benefits of the 1990 Clean Air Act Title IV (COVE), Phase 2, SO2 and NOX reduction provisions, to the visibility in typical eastern and western Class 1 areas. Probable bands of visibility impairment distribution curves are developed for Shenandoah National Park, Smoky Mountain National Park and the Grand Canyon National Park, based on the existing emissions, ``Base Case``, and for the COVE emission reductions, ``CAAA Case``. Emission projections for 2010 are developed with improved versions of the National Acid Precipitation Assessment Program emission projection models. Source-receptor transfer matrices created with the Advanced Statistical Trajectory Regional Air Pollution (ASTRAP) model are used with existing emission inventories and with the emission projections to calculate atmospheric concentrations of sulfate and nitrate at the receptors of interest for existing and projected emission scenarios. The Visibility Assessment Scoping Model (VASM) is then used to develop distributions of visibility impairment. VASM combines statistics of observed concentrations of particulate species and relative humidity with ASTRAP calculations of the relative changes in atmospheric sulfate and nitrate particulate concentrations in a Monte Carlo approach to produce expected distributions of hourly particulate concentrations and RH. Light extinction relationships developed in theoretical and field studies are then used to calculate the resulting distribution of visibility impairment. Successive Monte Carlo studies are carried out to develop sets of visibility impairment distributions with and without the COVE emission reductions to gain insight into the detectability of expected visibility improvements.

  2. A Basic Study on Countermeasure Against Aerodynamic Force Acting on Train Running Inside Tunnel Using Air Blowing

    NASA Astrophysics Data System (ADS)

    Suzuki, Masahiro; Nakade, Koji

    A basic study of flow controls using air blowing was conducted to reduce unsteady aerodynamic force acting on trains running in tunnels. An air blowing device is installed around a model car in a wind tunnel. Steady and periodic blowings are examined utilizing electromagnetic valves. Pressure fluctuations are measured and the aerodynamic force acting on the car is estimated. The results are as follows: a) The air blowing allows reducing the unsteady aerodynamic force. b) It is effective to blow air horizontally at the lower side of the car facing the tunnel wall. c) The reduction rate of the unsteady aerodynamic force relates to the rate of momentum of the blowing to that of the uniform flow. d) The periodic blowing with the same frequency as the unsteady aerodynamic force reduces the aerodynamic force in a manner similar to the steady blowing.

    In this study, we sought to assess what portion, if any, of the reductions in ambient concentrations of particulate matter (PM*) < or = 2.5 microm in aerodynamic diameter (PM2.5) that occurred in the United States between the years 1999 and 2006 can be attributed to reductions in emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from implementation of Phase 2 of Title IV of the 1990 Clean Air Act Amendments. To this end, a detailed statistical model linking sources and monitors over time and space was used to estimate associations between the observed emissions reductions and improvements in air quality. Overall, it turned out to be quite feasible to use relatively transparent statistical methods to assess these outcomes of the Phase 2 program, which was designed to reduce long-range transport of emissions. Associations between changes in emissions from individual power plants and monitor-specific estimates of changes in concentrations of PM2.5, our indicator pollutant, were highly significant and were mostly of the expected relative magnitudes with respect to distances and directions from sources. Originally estimated on monthly data for a set of 193 monitors between 1999 and 2005, our preferred model performed equally well using data for the same 193 monitors for 2006 as well as for an additional 217 monitors not in the original set in 2006. Although substantial model uncertainty was observed, we were able to estimate that the Title IV Phase 2 emissions reduction program implemented between 1999 and 2005 reduced PM2.5 concentrations in the eastern United States by an average of 1.07 microg/m3 (standard deviation [SD] = 0.11 microg/m3) compared with a counterfactual case defined as there having been no change in emission rates per unit of energy input (1 million British thermal units [BTUs]). On a population-weighted basis, the comparable reduction in PM2.5 was 0.89 microg/m3. Compared with the air quality fate and transport models used by the

    The Clean Air Act Amendments of 1990, Title III, present a need for stationary source sampling and analytical methods for the list of 189 compounds. EPA has used Volatile Organic Sampling Train (VOST) and Semivolatile Organic Sampling Train (SemiVOST) sampling and analytical methods for the type of sampling of organic compounds in the past, but these methodologies have been completely validated for only a few of the organic compounds. In the study, the applicability of VOST and SemiVOST techniques to Clean Air Act halogenated compounds has been evaluated under laboratory conditions. The methods were evaluated first to determine whether the compounds could be analyzed successfully.

  7. California Clean Air Act: A compliance strategy for the City of San Diego`s non-emergency fleet

    Historically, parts of California have had the worst air quality in the nation. The California Energy Commission began experimenting with alternate fuels in the 1970`s in an effort to reduce harmful automobile emissions and hence, improve air quality. It is recognized that the costs to California which result from our air quality problems are immense. Ten to twenty billion dollars each year is the estimated damage in terms of health impacts, materials damages, lost agricultural crop output and forest damages. As the California population increases and health care costs escalate, the total monetary damages from air pollution will increase. The California Energy Commission goal to improve air quality became a mandate in 1988 with the passage of the California Clean Air Act (CCAA). The CCAA requires a revised air quality strategy for the San Diego district since we do not meet State air quality standards for smog, carbon monoxide and nitrogen dioxide. Smog remains San Diego`s major air quality problem, even though the annual number of days each year over the Federal standard has been reduced by 55 percent in the past ten years. Ten years ago about two-thirds of San Diego`s smog was transported from Los Angeles. Today more than 60 per cent of the days San Diego exceeds the State standard are from locally generated smog. It is estimated that 57% of the reactive hydrocarbon emissions (which react with nitrogen dioxide in the presence of sunlight to form smog) is from cars, trucks and buses. The Air Pollution Control District (part of the County of San Diego) is the office that the Air Resources Board has put in charge of creating regulations and designing strategy to reduce polluting emissions. The purpose of this project is to determine the full cost of acquiring and operating a municipal fleet which meets the mandates of the California Clean Air Act. With that information, a plan to meet the Clear Air Act (CCAA) requirements can be formulated by local government.

    Using dendroisotopic techniques, we show the recovery of Juniperus virginiana L. (eastern red cedar) trees in the Central Appalachian Mountains from decades of acidic pollution. Acid deposition over much of the 20th century reduced stomatal conductance of leaves, thereby increasing intrinsic water-use efficiency of the Juniperus trees. These data indicate that the stomata of Juniperus may be more sensitive to acid deposition than to increasing atmospheric CO2. A breakpoint in the 100-y δ(13)C tree ring chronology occurred around 1980, as the legacy of sulfur dioxide emissions declined following the enactment of the Clean Air Act in 1970, indicating a gradual increase in stomatal conductance (despite rising levels of atmospheric CO2) and a concurrent increase in photosynthesis related to decreasing acid deposition and increasing atmospheric CO2. Tree ring δ(34)S shows a synchronous change in the sources of sulfur used at the whole-tree level that indicates a reduced anthropogenic influence. The increase in growth and the δ(13)C and δ(34)S trends in the tree ring chronology of these Juniperus trees provide evidence for a distinct physiological response to changes in atmospheric SO2 emissions since ∼1980 and signify the positive impacts of landmark environmental legislation to facilitate recovery of forest ecosystems from acid deposition.

    Title IV of the Clean Air Act Amendments of 1990 (CAAA), Acid Deposition Control,' will reduce by the year 2000 annual sulfur dioxide emissions by 10 million tons below the 1980 level, and nitrogen oxide emissions by 2 million tons. Emissions of sulfur dioxide will then be limited to 8.95 million tons per year after 2000. To control sulfur dioxide emissions, Title IV created a new regulatory instrument -- an emission allowance or credit -- that electric power producers (utilities and others) will be required to possess and expend to emit sulfur dioxide into the atmosphere. Electric utilities and others will be allowed to buy and sell the emission allowances in an allowance trading system. Cost estimates of implementing Title IV provisions put the cost 50 to 75 percent higher than with the allowance trading system. Estimates of this potential savings vary from 1 to 3 billion dollars annually. This report discusses the administrative roles of various agencies in implementing Title IV and allocating the emission allowance. The cost of compliance and the effect of compliance on the utilities industry is discussed.

    The Clean Air Act Amendments of 1990 imposed the requirement for a comprehensive set of state air pollution permit programs on a nationwide basis for the first time. Prior to the passage of this law, there were about thirty-five state permit programs, and they were not subject to Federal supervision. During the debate in the House of Representives it was stated that the purpose of the permit program was to clarify and make more enforceable a source`s pollution control requirements. In addition, the Congress wanted to encourage public involvement in the process so that interested citizens will be able to review and help enforce a source`s obligations under the Act.

    The 1952 “Killer Smog” left over 4000 citizens of Greater London dead in a single week. It was a highly visible environmental disaster, which pinned the British government with responsibility over factory and domestic coal smoke pollution. Within four years of the Smog, the British parliament passed the 1956 Clean Air Act, which was designed primarily to prevent the release of dark smoke from the chimneys of private dwellings and factories. This act is considered a significant turning point in the history of environmental regulation. Through the analysis of confidential documents from government ministries and Members of Parliament, my research has focused on how decisions were made following this man-made environmental catastrophe. The primary focus of this presentation will be to explore why the British government appeared lethargic in the face of its long-standing coal pollution problem and why it finally passed the first clean air act in the world. In this case, establishing responsibility and organizing research were the major time constraints on policy action. In the months following the 1952 Smog, government departments passed off responsibility and quarreled over jurisdiction in the smog matter. Ministries held responsible for air pollution jointly established the Committee on Air Pollution to find a solution to urban smog. In the years following, the Committee on Air Pollution compiled research on the health effects and economic impact of air pollution, deriving its information from a variety of sources. In its 1954 final report, the committee named smoke and sulfur dioxide the most likely culprits of the 1952 deaths, and it recommended the elimination of smoke-producing coal from the British market, a major change to how the British fueled their homes and factories. The resulting 1956 Clean Air Act was the product of numerous compromises over the economic, political, and social issues present in Great Britain at the time. The British government

  2. Interactions between energy efficiency and emission trading under the 1990 Clean Air Act Amendments

    The 1990 Clean Air Act Amendments affect electric utilities in numerous ways. The feature that probably has received the greatest attention is the provision to let utilities trade emissions of sulfur dioxide (SO{sub 2}), while at the same time requiring them to reduce S0{sub 2} emissions in 2000 by an aggregate 43%. The emission trading system was welcomed by many as a way of reducing the cost of reducing emissions, by providing greater flexibility than past approaches. This report examines some of the potential interactions between trading emissions and increasing end-use energy efficiency. The analysis focuses on emission trading in the second phase of the trading program, which begins in 2000. The aggregate effects, calculated by an emission compliance and trading model, turn out to be rather small. Aggressive improvement of end-use efficiency by all utilities might reduce allowance prices by $22/ton (1990 dollars), which is small compared to the reduction that has occurred in the estimates of future allowance prices and when compared to the roughly $400/ton price we estimate as a base case. However, the changes in the allowance market that result are large enough to affect some compliance decisions. If utilities in only a few states improve end-use efficiency aggressively, their actions may not have a large effect on the price of an allowance, but they could alter the demand for allowances and thereby the compliance decisions of utilities in other states. The analysis shows how improving electricity end-use efficiency in some states can cause smaller emission reductions in other states, relative to what would have happened without the improvements. Such a result, while not surprising given the theory behind the emission trading system, is upsetting to people who view emissions, environmental protection, and energy efficiency in moral rather than strictly economic terms.

    The National Regulatory Research Institute (NRRI), with funding from the US Environmental Protection Agency (EPA) and the US Department of Energy (DOE), conducted four regional workshops` on state public utility commission implementation of the Clean Air Act Amendments of 1990 (CAAA). The workshops had four objectives: (1) to discuss key issues and concerns on CAAA implementation, (2) to encourage a discussion among states on issues of common interests, (3) to attempt to reach consensus, where possible, on key issues, and (4) to provide the workshop participants with information and materials to assist in developing state rules, orders, and procedures. From the federal perspective, a primary goal was to ensure that workshop participants return to their states with a comprehensive background and understanding of how state commission actions may affect implementation of the CAAA and to be able to provide guidance to their jurisdictional utilities. It was hoped that this would reduce some of the uncertainty utilities face and assist in the development of an efficient allowance market. This report is divided into two main sections. In Section II, eleven principal issues are identified and discussed. These issues were chosen because they were either the most frequently discussed or they were related to the questions asked in response to the speakers` presentations. This section does not cover all the issues relevant to state implementation nor all the issues discussed at the workshops; rather, Section II is intended to provide an overview of the,planning, ratemaking, and multistate issues. Part III is a series of workshop papers presented by some of the speakers. Individual papers have been cataloged separately.

    The National Regulatory Research Institute (NRRI), with funding from the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE), conducted two workshops on state public utility commission implementation of the Clean Air Act Amendments of 1990 (CAAA). The first workshop was held in Charlotte, North Carolina for southern and eastern states in April 1992 and the second was held in St. Louis, Missouri for Midwestern states in May. The workshops had four objectives: (1) discuss key issues and concerns on CAAA implementation, (2) encourage a discussion among states on issues of common interest, (3) attempt to reach consensus, where possible, on some key issues, and (4) provide the workshop participants with information and materials to assist in developing rules, orders, and procedures in their state.

  5. An analysis of SO{sub 2} emission compliance under the 1990 Clean Air Act Amendments

    The effectiveness of SO{sub 2} emission allowance trading under Title 4 of the 1990 Amendments to the Clean Air Act (CAA) is of great interest due to the innovative nature of this market incentive approach. However, it may be a mistake to frame the compliance problem for a utility as a decision to trade or not. Trading of allowances should be the consequence, not the decision. The two meaningful decision variables for a utility are the control approaches chosen for its units and the amount of allowances to hold in its portfolio of assets for the future. The number allowances to be bought or sold (i.e. traded) is determined by the emission reduction and banking decisions. Our preferred approach is to think of the problem in terms of ABC`s of the 1990 CAA Amendments: abatement strategy, banking, and cost competitiveness. The implications of the general principles presented in this paper on least cost emission reductions and emissions banking to hedge against risk are being simulated with version 2 of the ARGUS model representing the electric utility sector and regional coal supplies and transportation rates. A rational expectations forecast for allowances prices is being computed. The computed allowance price path has the property that demand for allowances by electric utilities for current use or for banking must equal the supply of allowances issued by the federal government or provided as forward market contracts in private market transactions involving non-utility speculators. From this rational expectations equilibrium forecast, uncertainties are being explored using sensitivity tests. Some of the key issues are the amount of scrubbing and when it is economical to install it, the amount of coal switching and how much low sulfur coal premiums will be bid up; and the amount of emission trading within utilities and among different utilities.

  6. Interactions Between Energy Efficiency and Emission Trading Under the 1990 Clean Air Act Amendments

    Title IV of the 1990 Clean Air Act Amendments (P.L. 101-549) requires electric utilities to reduce emissions of precursors of acid precipitation, specifically sulfur dioxide (SO{sub 2}) and oxides of nitrogen (NO{sub x}), starting at 261 generating units in 1995 and covering most fossil-fired units in 2000. The Amendments take a conventional command-and-control approach to reducing NO{sub x}, but they established a market-based regulatory system to reduce SO{sub 2}. Under this system, utilities that own fossil-fired power plants in the conterminous 48 states and the District of Columbia are granted the right, in the form of allowances, to emit a specified number of tons of SO{sub 2}. A utility that wants to do so may reduce emissions more than required by the number of allowances it receives and then either sell its excess allowances to other utilities or bank them for future use. Alternatively, it can buy additional allowances from other utilities who may wish to sell, and emit more than its original allocation would have permitted, provided that it holds enough allowances from some source to cover emissions. The research described here attempts to estimate how large these interacting effects might be and how they might affect the choices that utilities make when complying with Title IV of the Amendments. They do so using a model that was designed to estimate what options electric utilities might choose in complying with Title IV, and what effects compliance would have on electricity costs. The model assumes that the allowance trading system would work as smoothly as the economic theory on which the system is based. Actual compliance decisions announced to date have been somewhat different from what theory and the model project. They discuss some of the reasons for these differences and the likely effects these differences may have on the interaction between allowance trading and energy efficiency.

  7. Allowance trading under the Clean Air Act: Who should regulate, and when?

    The goal of this paper is to explore how compliance with the Clean Air Act Amendments of 1990 (CAAA), especially Title IV and emission trading under it, will affect the current relationship between state and federal regulation. It is difficult, with the limited experience we have had under Title IV, to be definitive about or to be a very strong advocate of too many policy positions. What may be most helpful at this point is to identify where the difficult issues in state/federal relations might arise; and then to explore ways in which tensions might be either avoided or resolved. One anticipated conclusion is that a traditional regulatory mindset could be very destructive if applied to this new area of oversight without due sensitivity to what Congress is trying to achieve in Title IV. That concern pervaded the early legislative debates; and it persists today. Title IV presents some unique challenges to state regulators and will require some creative solutions and fresh thinking if the goals of Congress are to be realized and the full benefits that allowance trading can offer are to be reaped by electricity consumers. In the ultimate analysis, Title IV amounts to a massive internalization of the external costs imposed on society by acid rain deposition. (This places in serious question the notion of additional externality {open_quotes}adders{close_quotes} for sulfur dioxide (SO{sub 2}) and nitrous oxide (NO{sub x}) at the state level for utility supply planning purposes.) The whole point of Title IV is to give those directly charged with compliance, namely power producers, the maximum flexibility to pursue least-cost compliance solutions. Perhaps the biggest single factor in how well they do this will be how state regulators respond to their compliance and allowance trading initiatives.

    The regulation of hazardous air pollutants by Title III of the Clean Air Act Amendments of 1990 has a potential wide-ranging impact for the natural gas industry. Title III includes a list of 189 hazardous air pollutants (HAPs) which are targeted for reduction. Under Title III, HAP emissions from major sources will be reduced by the implementation of maximum achievable control technology (MACT) standards. If the source is defined as a major source, it must also comply with Title V (operating permit) and Title VII (enhanced monitoring) requirements. This presentation will review Title III`s effect on the natural gas industry by discussing the regulatory requirements and schedules associated with MACT as well as the control technology options available for affected sources.

  1. Detection of direct-acting mutagens in ambient air: A comparison of two highly sensitive mutagenicity assays

    Ambient air has been shown to contain numerous hazardous pollutants, many of which are known or suspected carcinogens and mutagens. Bioassays play a prominent role in the characterization of these genotoxic pollutants, and as new test methods are developed, it is incumbent upon researchers to evaluate assay performance and report relative merits. In this study, two Salmonella test methods (the spiral and preincubation assays) were assessed to determine their usefulness as screening methods for monitoring direct-acting mutagens in ambient air. The spiral assay automates the conventional plate-incorporation assay and has been shown to reduce the labor, materials, and sample mass required to perform mutagenicity testing. The preincubation assay has been shown to enhance test sensitivity for certain classes of compound, thereby reducing the amount of sample required for dose-response analysis. Both assays were used to test organic extracts of airborne particulate matter collected in Tokyo during the winters of 1988 and 1990. In addition to the conventional tester strains TA98 and TA100, two newly developed YG strains were evaluated. Strains YG1024 and YG1029-derived from TA98 and TA100, respectively-contain an acetyltransferase plasmid that confers upon the strains greater sensitivity towards nitroarenes. Results from this study indicated that both assays were able to detect direct-acting mutagens in the Tokyo air samples. The mutagenic activity associated with the samples was directly related to the particle mass present in a given volume of air. Mutagenic response was greater in the spiral assay relative to the preincubation assay, especially when YG tester strains were used. The YG strains were significantly more sensitive to mutation than the TA strains in both assays, which suggests that nitroaromatics are an important class of genotoxic contaminant present in Tokyo air.

    The consolidated chemical list includes chemicals subject to reporting requirements under Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA), also known as the Emergency Planning and Community Right-to-Know Act (EPCRA), and chemicals listed under section 112(r) of Title III the Clean Air Act (CAA) Amendments of 1990. This consolidated list has been prepared to help firms handling chemicals determine whether they need to submit reports under sections 302, 304, or 313 of SARA Title III (EPCRA) and, for a specific chemical, what reports may need to be submitted. Separate lists are also provided of Resource Conservation and Recovery Act (RCRA) waste streams and unlisted hazardous wastes, and of radionuclides reportable under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). These lists should be used as reference tool, not as a definitive source of compliance information. The chemicals on the consolidated list are ordered by Chemical Abstract Service (CAS) registry number. Categories of chemicals, which do not have CAS registry numbers, but which are cited under CERCLA, EPCRA section 313, and the CAA, are placed at the end of the list. More than one chemical name may be listed for one CAS number, because the same chemical may appear on different lists under different names.

    The Clean Air Act of 1990 regulates the emission of 198 air toxics. Currently, there is no existing technology by which a regulatory agency can independently determine if a facility is in compliance. We have successfully tested the ability of passive-remote Fourier transform infrared (FTIR) spectroscopy to detect chemical plumes released in the field. Additional laboratory releases demonstrated that FTIR spectroscopy can detect target analytes in mixtures containing components which have overlapping absorbances. The FTIR spectrometer was able to identify and quantify each component released with an average quantitative error of less than 20% using partial least squares (PLS) analysis and 40% using classical least squares analysis (CLS) when calibration files containing pure components and mixtures were used. Calibration files containing only pure analytes resulted in CLS outperforming PLS analyses.

  6. The Clean Air Act Amendments of 1990 and industry; Title I non-attainment areas

    SciTech Connect

    Saunders, G.L. ); Laznow, J. )

    1991-10-01

    The signing into law of the CAA Amendments of 1990 will bring sweeping changes affecting significantly the way industry is regulated. This paper reports that the Amendments address a wide range of issues, including non- attainment areas, toxic air pollutants, acid rain, operating permits and fees, and regulatory enforcement. Regulations to be promulgated under the Amendments will stand in stark contrast to those promulgated after CAA was last amended in 1977. Many of the issues addressed by the 1990 Amendments have accumulated for years, waiting for legislation consideration. Title I of the Amendments sets National Ambient Air Quality Standards (NAAQS) for several criteria pollutants. The standard for ozone is of greatest general interest for stationary sources, along with requirements for control of nitrogen oxides (NO{sub x}) and VOCs.

    Two studies found that, although the nation's wealthiest gave a smaller proportion of earnings to charity in the 1980s, the number of wealthy donors has increased. Tax law changes had less effect than predicted. Generosity appears divided between a few who give a lot and many who give little. (MSE)

  8. Ozone: An Air Pollutant Acting as a Plant-Signaling Molecule

    NASA Astrophysics Data System (ADS)

    Sandermann, Heinrich, Jr.

    The air pollutant ozone has recently been found to trigger plant signal transduction chains resembling those induced by fungal and viral pathogens. Chloroplast-related functions are generally inhibited, while genes of antioxidative and pathogen defense are activated. The resulting perturbation of plant metabolism leads to higher susceptibility (or in certain cases higher tolerance) for other abiotic and biotic stressors. This mechanism of action links ozone by some criteria to "novel" forest decline and to agricultural crop loss. Further progress appears to depend on coordinated long-term laboratory and field experiments.

  9. The effects of Title IV of the Clean Air Act amendments of 1990 on electric utilities: An update

    SciTech Connect

    1997-03-01

    This report presents data and analyses related to Phase I implementation of the Clean Air Act Amendment by electric utilities. It describes the strategies used to comply with the Acid Rain Program in 1995, the effect of compliance on sulfur dioxide emissions levels, the cost of compliance, and the effects of the program on coal supply and demand. The first year of Phase I demonstrated that the market-based sulfur dioxide emissions control system could achieve significant reductions in emissions at lower than expected costs. Some utilities reduced aggregate emissions below legal requirements due to economic incentives; other utilities purchased additional allowances to avoid noncompliance. More than half of the utilities switched to or blended with lower sulfur coal, due to price reductions in the coal market which were partially due to the allowance trading program. 21 figs., 20 tabs.

  10. Contact sheet recording with a self-acting negative air bearing

    2000-01-01

    A flat head and a tape transport arrangement impart a wrap angle to the tape at the upstream corner of the head. The wrap angle, corner sharpness and tape stiffness are sufficient to cause a moving tape to form a hollow bump at the upstream corner, thereby creating a hollow into which entrained air can expand, causing a subambient pressure within and downstream of the bump. This pressure keeps the tape in contact with the head. It is created without the need for a groove or complex pressure relief slot(s). No contact pressure arises at the signal exchange site due to media wrap. The highest contact pressures are developed at a wrapped upstream corner. For a tape drive, traveling in both forward and reverse, the wrap can be at both the upstream and downstream (which is the reverse upstream) corners. Heads that are not flat can also be used, if the wrap angle relative to a main surface is sufficient and not too large. The wrapped head can also be used with rotating media, such as disks (floppy and hard) and rotating heads, such as helical wound heads for video recording. Multiple flat tape bearing surfaces can be separated by grooves and/or angles. Each flat can carry heads along one or more gap lines. Multiple adjacent narrow tracks can thus be written for extreme high track density recording.

  12. Prospective memory in an air traffic control simulation: External aids that signal when to act

    PubMed Central

    Loft, Shayne; Smith, Rebekah E.; Bhaskara, Adella

    2011-01-01

    At work and in our personal life we often need to remember to perform intended actions at some point in the future, referred to as Prospective Memory. Individuals sometimes forget to perform intentions in safety-critical work contexts. Holding intentions can also interfere with ongoing tasks. We applied theories and methods from the experimental literature to test the effectiveness of external aids in reducing prospective memory error and costs to ongoing tasks in an air traffic control simulation. Participants were trained to accept and hand-off aircraft, and to detect aircraft conflicts. For the prospective memory task participants were required to substitute alternative actions for routine actions when accepting target aircraft. Across two experiments, external display aids were provided that presented the details of target aircraft and associated intended actions. We predicted that aids would only be effective if they provided information that was diagnostic of target occurrence and in this study we examined the utility of aids that directly cued participants when to allocate attention to the prospective memory task. When aids were set to flash when the prospective memory target aircraft needed to be accepted, prospective memory error and costs to ongoing tasks of aircraft acceptance and conflict detection were reduced. In contrast, aids that did not alert participants specifically when the target aircraft were present provided no advantage compared to when no aids we used. These findings have practical implications for the potential relative utility of automated external aids for occupations where individuals monitor multi-item dynamic displays. PMID:21443381

  13. Stratospheric ozone protection: The Montreal Protocol and Title VI of the Clean Air Act Amendments of 1990

    SciTech Connect

    Babst, C.R. III

    1993-08-01

    The stratospheric ozone layer protects the surface of the Earth from harmful ultraviolet (UV-B) radiation, which has been causally linked to skin cancer and cataracts, suppression of the human immune system, damage to crops and aquatic organisms, the formation of ground-level zone and the rapid weathering of outdoor plastics. In recent years, scientists have observed a significant deterioration of the ozone layer, particularly over the poles, but increasingly over populated regions as well. This deterioration has been attributed to the atmospheric release of certain man-made halocarbons, including chlorofluorocarbons (CFCs), halons, methyl chloroform and carbon tetrachloride. Once used extensively as propellants for aerosol sprays (but generally banned for such purposes since 1978), CFCs are widely used today as refrigerants, foams and solvents. All of these chlorinated (CFC, methyl chloroform and carbon tetrachloride) and brominated (halon) compounds are classified for regulatory purposes as Class I substances because of their significant ozone-depleting potential. Hydrochlorofluorocarbons (HCFCs), developed as alternatives to CFCs and halons for many different applications, have been classified for regulatory purposes as Class II substances because of their relatively less destructive impact on stratospheric ozone. This paper describes the following regulations to reduce destruction of the ozone layer: the Montreal Protocol; Title VI of the Clean air Act Amendments of 1990; Accelerated Phase-out schedules developed by the countries which signed the Montreal Protocol; Use restrictions; Recycling and Emission reduction requirements; Servicing of motor vehicle air conditions; ban on nonessential products; labeling requirements; safe alternatives. 6 refs.

  1. A bottom-up art event gave birth to a process of community empowerment in an Italian village.

    2012-03-01

    Although community participation is a component of community empowerment, it often remains a theoretical exhortation. Reporting experiences which enable people to take control of their lives, can be useful to suggest practical elements for promoting empowerment. This article describes the experience of a Sardinian village (Ulassai), that developed into a community empowerment. The Laverack's operational domains were used to measure the community empowerment process. The process started in 1979 'almost by chance' with an art performance that was the entry point for community participation. This experience has been the foundation for the community empowerment. Citizens acquired the 'ability of thinking and planning as a community and not mere individuals'. In the following 30 years citizens gave birth to several outcomes rooted in that event. The intermediate outcomes highlight the 'ability of action by a group to mobilize existing resources, and act collectively against opposing forces'. The long-term outcomes demonstrate the 'ability to integrate the cultural experiences that strengthened the community's identification into a sustainable community asset', and the 'ability to cope with global environmental challenges and to collaborate on an equal basis with other stakeholders. The pathways to community empowerment, showed by the community of Ulassai, overlap with the 'operational domains'. The Ulassai experience shows that the empowerment process can start from an event apparently unrelated to health promotion. This community experience illustrates the positive role arts can play in community development. Hence, the call for health promoters to look carefully into those situations that occur naturally in communities. PMID:24801310

    The Adirondack Mountain region is an extensive geographic area (26,305 km(2)) in upstate New York where acid deposition has negatively affected water resources for decades and caused the extirpation of local fish populations. The water quality decline and loss of an established brook trout (Salvelinus fontinalis [Mitchill]) population in Brooktrout Lake were reconstructed from historical information dating back to the late 1880s. Water quality and biotic recovery were documented in Brooktrout Lake in response to reductions of S deposition during the 1980s, 1990s, and 2000s and provided a unique scientific opportunity to re-introduce fish in 2005 and examine their critical role in the recovery of food webs affected by acid deposition. Using C and N isotope analysis of fish collagen and state hatchery feed as well as Bayesian assignment tests of microsatellite genotypes, we document in situ brook trout reproduction, which is the initial phase in the restoration of a preacidification food web structure in Brooktrout Lake. Combined with sulfur dioxide emissions reductions promulgated by the 1990 Clean Air Act Amendments, our results suggest that other acid-affected Adirondack waters could benefit from careful fish re-introduction protocols to initiate the ecosystem reconstruction of important components of food web dimensionality and functionality.

  3. Human health benefits of ambient sulfate aerosol reductions under Title IV of the 1990 Clean Air Act amendments

    The Acid Rain Provisions (Title IV) of the Clean Air Act Amendments of 1990 call for about a 10 million ton reduction in annual SO{sub 2} emissions in the United States by the year 2010. Although the provisions apply nationwide, most of the reduction will take place in the eastern half of the United States, where use of high sulfur coal for electricity generation is most common. One potentially large benefit of Title IV is the expected reduction in adverse human health effects associated with exposure to ambient sulfate aerosols, a secondary pollutant formed in the atmosphere when SO{sub 2} is present. Sulfate aerosols are a significant constituent of fine particulate (PM{sub 2.5}). This paper combines available epidemiologic evidence of health effects associated with sulfate aerosols and economic estimates of willingness to pay for reductions in risks or incidence of health effects with available estimates of the difference between expected ambient sulfate concentrations in the eastern United States and southeastern Canada with and without Title IV to estimate the expected health benefits of Title IV. The results suggest a mean annual benefit in the eastern United States of $10.6 billion (in 1994 dollars) in 1997 and $40.0 billion in 2010, with an additional $1 billion benefit each year in Ontario and Quebec provinces.

  4. The application of genetic information for regulatory standard setting under the clean air act: a decision-analytic approach.

    2008-08-01

    In 2002, the U.S. Environmental Protection Agency (EPA) released an "Interim Policy on Genomics," stating a commitment to developing guidance on the inclusion of genetic information in regulatory decision making. This statement was followed in 2004 by a document exploring the potential implications. Genetic information can play a key role in understanding and quantifying human susceptibility, an essential step in many of the risk assessments used to shape policy. For example, the federal Clean Air Act (CAA) requires EPA to set National Ambient Air Quality Standards (NAAQS) for criteria pollutants at levels to protect even sensitive populations from adverse health effects with an adequate margin of safety. Asthmatics are generally regarded as a sensitive population, yet substantial research gaps in understanding genetic susceptibility and disease have hindered quantitative risk analysis. This case study assesses the potential role of genomic information regarding susceptible populations in the NAAQS process for fine particulate matter (PM(2.5)) under the CAA. In this initial assessment, we model the contribution of a single polymorphism to asthma risk and mortality risk; however, multiple polymorphisms and interactions (gene-gene and gene-environment) are known to play key roles in the disease process. We show that the impact of new information about susceptibility on estimates of population risk or average risk derived from large epidemiological studies depends on the circumstances. We also suggest that analysis of a single polymorphism, or other risk factor such as health status, may or may not change estimates of individual risk enough to alter a particular regulatory decision, but this depends on specific characteristics of the decision and risk information. We also show how new information about susceptibility in the context of the NAAQS for PM(2.5) could have a large impact on the estimated distribution of individual risk. This would occur if a group were

  6. Clean Air Act Title III accidental emission release risk management program, and how it applies to landfills

    SciTech Connect

    Hibbard, C.S.

    1999-07-01

    On June 20, 1996, EPA promulgated regulations pursuant to Title III of the Clean Air Act (CAA) Amendments of 1990 (Section 112(r)(7) of the CAA). The rule, contained in 40 CFR Part 68, is called Accidental Release Prevention Requirements: Risk Management Programs, and is intended to improve accident prevention and emergency response practices at facilities that store and/or use hazardous substances. Methane is a designated highly hazardous chemical (HHC) under the rule. The rule applies to facilities that have 10,000 pounds of methane or more in any process, roughly equivalent to about 244,000 cubic feet of methane. The US EPA has interpreted this threshold quantity as applying to landfill gas within landfills. This paper presents an overview of the Accidental Release Prevention regulations, and how landfills are affected by the requirements. This paper describes methodologies for calculating the threshold quantity of landfill gas in a landfill. Methane is in landfill gas as a mixture. Because landfill gas can burn readily, down to concentrations of about five percent methane, the entire landfill gas mixture must be treated as the regulated substance, and counts toward the 10,000-pound threshold. It is reasonable to assume that the entire landfill gas collection system, active or passive, is filled with landfill gas, and that a calculation of the volume of the system would be a calculation of the landfill gas present in the process on the site. However, the US EPA has indicated that there are some instances in which pore space gas should be included in this calculation. This paper presents methods available to calculate the amount of pore space gas in a landfill, and how to determine how much of that gas might be available for an explosion. The paper goes through how to conduct the release assessment to determine the worst-case hazard zone around the landfill.

    Since the Surgeon General's groundbreaking report of 1964, "Smoking and Health," the medical and scientific communities have uncovered the devastating effects of tobacco smoke on health. In reaction to these findings, local and state governments have enacted a variety of clean air acts to prevent unnecessary exposure to this known carcinogen. The Nevada Clean Indoor Air Act (NCIAA), a non-comprehensive smoke-free law, permits smoking in designated areas of casinos, bars, and taverns. With many Las Vegas casinos catering to all ages, this study was designed to evaluate the efficacy of NCIAA in protecting children from second hand smoke exposure. Using a device that measures ambient air particle matter concentrations, this study sampled the air quality in 15 casino gaming areas and corresponding non-smoking, children-friendly areas. The results indicate that current policy fails to preserve indoor air quality in these children-friendly areas. Furthermore, this research suggests the adoption of a more comprehensive, 100% smoke-free policy as the only effective remedy. PMID:23113419

  14. Patients with Gastric Antral Vascular Ectasia (GAVE) Are at a Higher Risk of Gastrointestinal Bleeding in the Absence of Cirrhosis

    PubMed Central

    Wang, Jennifer; Stine, Jonathan G.; Cornella, Scott L.; Argo, Curtis K.; Cohn, Steven M.

    2015-01-01

    Background and Aims: Gastric antral vascular ectasia (GAVE) is commonly found in patients with cirrhosis, but it is also associated with other diseases in the absence of cirrhosis. Whether GAVE confers a different severity of gastrointestinal (GI) bleeding between patients with and without cirrhosis remains unknown. We aim to examine whether there is a difference in clinically significant GI bleeding due to GAVE in patients with or without cirrhosis. Methods: This is a retrospective case-control study of patients who were diagnosed with GAVE between January 2000 and June 2014. Patients were categorized into cirrhosis and noncirrhosis groups, and those with an additional GI bleeding source were excluded. Univariate comparisons and multivariable models were constructed using logistic regression. Results: In total, 110 patients diagnosed with GAVE on esophagogastroduodenoscopy (EGD) were included in our analysis; 84 patients had cirrhosis (76.4%) and 26 (23.6%) did not. Active GI bleeding was more prevalent in patients without cirrhosis (63.4% vs. 32.1%, p=0.003) despite similar indications for EGD, and endoscopic treatment with argon plasma coagulation (APC) was required more often in this group, approaching statistical significance (27% vs. 10.7%, p=0.056). There was no difference in bleeding severity, as evidenced by similar re-bleeding rates, surgery, or death attributed to uncontrolled bleeding. The strongest independent risk factor for GI bleeding was the absence of cirrhosis (odds ratio (OR): 5.151 (95% confidence interval (CI): 1.08-24.48, p=0.039). Conclusions: Patients with GAVE in the absence of cirrhosis are at higher risk for active GI bleeding and require more frequent endoscopic treatment than similar patients with cirrhosis. It may be worthwhile to treat GAVE in this population even in the absence of active bleeding. PMID:26807380

  15. Recurrent Tandem Gene Duplication Gave Rise to Functionally Divergent Genes in Drosophila

    2008-01-01

    Tandem gene duplication is one of the major gene duplication mechanisms in eukaryotes, as illustrated by the prevalence of gene family clusters. Tandem duplicated paralogs usually share the same regulatory element, and as a consequence, they are likely to perform similar biological functions. Here, we provide an example of a newly evolved tandem duplicate acquiring novel functions, which were driven by positive selection. CG32708, CG32706, and CG6999 are 3 clustered genes residing in the X chromosome of Drosophila melanogaster. CG6999 and CG32708 have been examined for their molecular population genetic properties (Thornton and Long 2005). We further investigated the evolutionary forces acting on these genes with greater sample sizes and a broader approach that incorporate between-species divergence, using more variety of statistical methods. We explored the possible functional implications by characterizing the tissue-specific and developmental expression patterns of these genes. Sequence comparison of species within D. melanogaster subgroup reveals that this 3-gene cluster was created by 2 rounds of tandem gene duplication in the last 5 Myr. Based on phylogenetic analysis, CG32708 is clearly the parental copy that is shared by all species. CG32706 appears to have originated in the ancestor of Drosophila simulans and D. melanogaster about 5 Mya, and CG6999 is the newest duplicate that is unique to D. melanogaster. All 3 genes have different expression profiles, and CG6999 has in addition acquired a novel transcript. Biased polymorphism frequency spectrum, linkage disequilibrium, nucleotide substitution, and McDonald–Kreitman analyses suggested that the evolution of CG6999 and CG32706 were driven by positive Darwinian selection.

    The Clean Air Act Amendments of 1990 (CAAA), Title III, present a need for stationary source sampling and analytical methods for the list of 189 toxic air pollutants. The US Environmental Protection Agency (EPA) has used VOST and SemiVOST sampling and analytical methods for a wide variety of volatile and semivolatile organic compounds in the past, but these methodologies have been completely validated for only a few of the organic compounds. The applicability of VOST and SemiVOST techniques to the halogenated organic compounds listed in Title III of the Clean Air Act Amendments of 1990 has been evaluated under laboratory conditions for chromatographic separation, mass spectrometric response, sorbent recovery and analytical method detection limit. Dynamic spiking techniques for the sampling trains (both gaseous and liquid dynamic spiking) were also evaluated in the laboratory. In the study, the VOST and SemiVOST methods were evaluated in the field at a fossil fuel power plant. The source was selected to provide actual stationary source emissions with the compounds of interest present in trace amounts or not present. The paper presents the results of the field validation of the VOST and SemiVOST sampling and analytical methods.

    Shannon, J.D.; Hanson, D.A.

    1997-08-01

    The Acid Rain Provisions (Title IV) of the 1990 Clean Air Act Amendments (CAAA) are designed to reduce the deposition of SO{sub 2} and sulfate and, to a lesser extent, the deposition of NO{sub x} and nitrate through reduction of SO{sub 2} and NO{sub x} emissions. However, other important benefits are anticipated from the emission control strategies, including improvement of regional visibility and reductions in concentrations of fine particles (PM2.5). In this study, the authors coupled utility emissions forecasts with the Advanced Statistical Trajectory Regional Air Pollution (ASTRAP) model and the Visibility Assessment Scoping Model (VASM) to calculate and compare the relative improvements by 2010 in visual impairment, PM2.5 concentrations, and sulfate wet deposition at selected sites in the eastern United States.

    Sulfate and free hydrogen ion concentrations in precipitation decreased 10 to 25 percent over large areas of the eastern United States in 1995. The largest decreases in both ions occurred in and downwind of the Ohio River Valley, the same area where Phase I of the 1990 Clean Air Act Amendments set limitations, effective January 1, 1995, on sulfur dioxide emissions from affected coal-fired sources. Based on the authors analysis of precipitation chemistry and emissions data, they conclude that substantial declines in acid rain occurred in the eastern United States in 1995 because of large reductions in sulfur dioxide emissions in the same region.

    Title 4 of the Clean Air Act Amendments of 1990 (CAAA) created a new regulatory instrument that electric power producers (utilities and others) will be required to possess and expand in order to emit sulfur dioxide (SO{sub 2}) into the atmosphere. The emission allowance system created by the CAAA will be grafted onto an already complex system of state and federal electric utility regulation. How public utility commissions (PUCs) and the Federal Energy Regulatory Commission (FERC) regulate these allowances will greatly affect the decisions that electric utilities under their jurisdiction make to comply with the CAAA and, therefore, the cost of compliance to ratepayers. 2 figs., 9 tabs.

  2. Environmental compliance guide. Guidance manual for Department of Energy compliance with the Clean Air Act: nonattainment areas

    SciTech Connect

    1982-09-01

    The purpose of this manual is to identify information requirements associated with air quality permit applications in areas for which ambient pollutant levels currently exceed the national ambient air quality standards (nonattainment areas). The manual is to be used by project managers at the US Department of Energy (DOE), in conjunction with the DOE Environmental Compliance Guide, to provide preliminary estimates of information required to obtain air quality permits for DOE projects. An analysis of nonattainment area permitting found that permitting of all sources in such areas is done on the state or local levels; the Environmental Protection Agency does not grant permits in nonattainment areas. As a result, Federal information requirements for permitting in nonattainment areas are somewhat vague. To provide a more realistic picture of nonattainment area permitting, selected state and local regulations were surveyed, and were found to contain more detail on the information required for permit approval. The most potentially demanding information requirements associated with nonattainment area permitting are the determination of Lowest Achievable Emission Rate, the negotiation of external emission offsets, and the consideration of the environmental impacts of project alternatives in ozone and carbon monoxide nonattainment areas. In any state, a few information requirements for nonattainment area permitting are likely to overlap with information requirements of other permitting processes, such as those in the Prevention of Significant Deterioration procedure. These requirements are emissions data and air quality modeling and its associated input data requirements (meteorology, topography, etc.).

    1994-12-31

    The coal industry has already begun to feel the affects of the acid deposition title, particularly in Illinois. Two challenges to the producers and sellers of coal; i.e., (1) Title III, Hazardous Air Pollutants and what is in store for customers, and (2) Title V, Operating Permits, which may affect production facilities are discussed. The utilities are temporarily exempted from Title III. The Great Waters report suggests that mercury will be regulated, and it looks like risk assessments will be based on coal analysis rather than on actual emission measurements. Stack sampling is difficult, expensive and slow. Coal cleaning is important in reducing trace elements. Electrostatic precipitators also remove trace elements. ESPs are less effective for mercury and selenium because they are emitted in the gas phase. FGD can remove hazardous air pollutants, but it is not well documented.

    2006-03-01

    In this study, the design of a multifarious classifier family for different applications is described. The main design and development steps are presented as well as some special techniques that have been applied to achieve preset objectives. It is shown by increasing the number of air supply channels to the classifier chamber (from 2 to 8), that the fine particle losses from adhesion onto the classifier walls can be reduced from 75% to less than 5% of the real dose for soft (spherical) agglomerates. By applying a bypass flow that is arranged as a co-axial sheath of clean air around the aerosol cloud from the classifier, the airflow resistance of the classifier can be controlled over a relatively wide range of values (0.023-0.041 kPa(0.5) min l(-1)). This, without affecting the fine particle dose or increasing the fine particle losses in the inhaler. Moreover, the sheath flow can be modelled to reduce the depositions in the induction port to the cascade impactor or in the patient's mouth, which are the result of back flows in these regions. The principle of powder induced pressure drop reduction across a classifier enables assessment of the amount of powder in the classifier at any moment during inhalation, from which classifier loading (from the dose system) and discharge rates can be derived. This principle has been applied to study the residence time of a dose in the classifier as function of the carrier size fraction and the flow rate. It has been found that this residence time can be controlled in order to obtain an optimal balance between the generated fine particle fraction and the inhalation manoeuvre of the patient. A residence time between 0.5 and 2 s at 60 l/min is considered favourable, as this yields a high fine particle dose (depending on the type of formulation used) and leaves sufficient inhaled volume for particle transport into the deep lung.

    The Clean Air Act Amendments of 1990 incorporate, for the first time, provisions aimed specifically at the control of acid rain. These provisions restrict emissions of sulfur dioxide (SO{sub 2}) and oxides of nitrogen (NO{sub x}) from electric power generating stations. The restrictions on SO{sub 2} take the form of an overall cap on the aggregate emissions from major generating plants, allowing substantial flexibility in the industry`s response to those restrictions. This report discusses one response scenario through the year 2030 that was examined through a simulation of the utility industry based on assumptions consistent with characterizations used in the National Energy Strategy reference case. It also makes projections of emissions that would result from the use of existing and new capacity and of the associated additional costs of meeting demand subject to the emission limitations imposed by the Clean Air Act. Fuel-use effects, including coal-market shifts, consistent with the response scenario are also described. These results, while dependent on specific assumptions for this scenario, provide insight into the general character of the likely utility industry response to Title IV.

    Start-stop tests were conducted on air-lubricated spiral-groove thrust bearings. Application of a matrix-bonded molybdenum disulfide (MoS2) coating over a porous chrome oxide coating resulted in significantly lower friction, compared to bearings coated with chrome oxide only. The MoS2 coated bearing sustained 15,000 start-stop cycles at a maximum of 3600 rpm. Each cycle was 15 seconds on, 30 seconds off. The chrome oxide coated bearing failed by local welding after 2030 cycles. Both types of coatings exhibited early failures under higher thrust loads when operating films were insufficient to sustain the load without overheating.

    The growing severity of our societal response to environmental misconduct is reflected, in part, by the criminalization of environmental wrongs by both state and Federal governments. Indeed, the recently enacted Clean Air Act Amendments of 1990 continue this trend, giving the Environmental Protection Agency, via the Department of Justice, significant new criminal enforcement tools. The importance attached to law enforcement of environmental laws is a relatively recent phenomenon and took a significant upswing in 1982 when the department of Justice created what is today the Environmental Crimes Section in what is now the Environment and Natural Resources Division, which section has grown steadily and now has over 25 attorneys who prosecute or assist in the prosecution of environmental crimes in the U.S.

    Two coatings for a Rayleigh step thrust bearing were tested when coasting down and stopping under self-acting operation in air. The thrust bearing had an outside diameter of 8.9 cm (3.5 in.), an inside diameter of 5.4 cm (2.1 in.), and nine sectors. The load was 73 N (16.4 lbf). The load pressure was 19.1 kN/per square meter (2.77 lbf/per square inch) on the total thrust bearing area. The chromium oxide coating was good to 150 stops without bearing deterioration, and the molybdenum disulfide coating was good for only four stops before bearing deterioration. The molybdenum disulfide coated bearing failed after nine stops.

    Title IV (acid rain) of the Clean Air Act Amendments of 1990 is imposing new limitations on the emission of sulfur dioxide (SO{sub 2}) and nitrogen oxides (N{sub x}) from electric power plants. The act requires utilities to develop compliance plans to reduce these emissions, and indications are that these plans will dramatically alter traditional operating procedures. A key provision of the SO{sub 2} control program deaned in Title IV is the creation of a system of emission allowances, with utilities having the option of complying by adjusting system emissions and allowance holdings. A compilation of SO{sub 2} compliance activities by the 110 utility plants affected by Phase I is summarized in this report. These compliance plans are presented in a tabular form, correlated with age, capacity, and power pool data. A large number of the Phase I units (46%) have chosen to blend or switch to lower sulfur coals. This choice primarily is in response to (1) prices of low-sulfur coal and (2) the need to maintain SO{sub 2} control flexibility because of uncertain future environmental regulations (e.g., air toxics, carbon dioxide) and compliance prices. The report also discusses the responses of state legislatures and public utility commissions to the compliance requirements in Title IV. Most states have taken negligible action regarding the regulatory treatment of allowances and compliance activities. To protect mine employment, states producing high-sulfur coal have enacted regulations encouraging continued use of that coal, but for the most part, this response has had little effect on utility compliance choices.

    Computer software packages approved by the U.S. Environmental Protection Agency (U.S. EPA), including CAP88-PC, are used by U.S. Department of Energy (U.S. DOE) sites to demonstrate compliance with the radionuclide air emission standard under the Clean Air Act. CAP88-PC version 3, was approved by the U.S. EPA in February 2006 for use by U.S. DOE facilities. Version 3 incorporates several major changes that have the potential to affect calculated doses relative to calculations using earlier versions. This analysis examined the types and magnitudes of changes to dose estimates for specific radionuclides calculated using the version 3 software compared with the previous versions. For parent radionuclides and for the total dose from radionuclide chains, total effective dose calculated with version 3 was compared to effective dose equivalent calculated with previous versions. Various comparisons were also performed to determine which of the updates in version 3 accounted for changes in overall dose estimates. CAP88-PC version 3 would produce substantially different results relative to previous versions of the code for a number of radionuclides, including some isotopes that may be present at U.S. DOE facilities, as well as those used for industrial and medical applications. In general, doses for many radionuclides were lower using version 3 but doses for a few key radionuclides increased relative to the previous versions. PMID:23803666

    Title V of the Clean Air Act (CAA) establishes a new permit program requiring major sources and sources subject to Title III (Hazardous Air Pollutants) to obtain a state operating permit. Historically, most states have issued operating permits for individual emission units. Under the Title V permit program, a single permit will be issued for all of the emission units at the facility much like the current National Pollutant Discharge Elimination System (NPDES) permit program. The permit will specify all reporting, monitoring, and record-keeping requirements for the facility. Sources required to obtain permits include (a) major sources that emit 100 tons per year or more of any criteria air contaminant, (b) any source subject to the HAP provisions of Title III, (c) any source subject to the acid rain provisions of Title IV, (d) any source subject to New Source Performance Standards, and (e) any source subject to new source review under the nonattainment or Prevention of Significant Deterioration provisions. The State of Tennessee Title V Operating Permit Program was approved by EPA on August 28, 1996. This paper will provide details of initiatives underway at US Department of Energy (DOE) Oak Ridge Reservation (ORR) Facilities for implementation of requirements under the Title V Operating Permit Program. The ORR encompasses three DOE Facilities: the Y-12 Plant, Oak Ridge National Laboratory (ORNL), and the East Tennessee Technology Park (ETTP). The Y-12 Plant manufactures component parts for the national nuclear weapons program; the ORNL is responsible for research and development activities including nuclear engineering, engineering technologies, and the environmental sciences; and the ETTP conducts a variety of research and development activities and is the home of a mixed waste incinerator. Each of the three DOE Facilities is considered a major source under Title V of the CAA.

    Utilities are developing sulfur dioxide (SO{sub 2}) emission compliance plans to meet limitations of the Clean Air Act Amendments of 1990 (CAAA). Compliance plans will have long-term effects on resource selection, fuel choice, and system dispatch. Use of integrated resource planning (IRP) is necessary to ensure compliance plans are consistent with the overall societal goals. In particular, environmental externalities must be integrated with the compliance planning process. The focus of the CAAA is on air pollution reduction, specifically acid gases and toxics, and attainment of National Ambient Air Quality Standards (NAAQS) for criteria pollutants. Title IV specifically focuses on sulfur dioxide with a national allowance trading system, while further regulation of toxics and nitrogen oxides is slated for additional study. Yet, compliance planning based narrowly upon today`s environmental regulations could fail to meet the broad goals of IRP if a larger array of environmental externalities is excluded from the analysis. Compliance planning must consider a broad range of environmental effects from energy production and use to (1) protect society`s long-term stake in environmental quality, and (2) ensure that today`s plans are rich enough to accommodate potential changes in regulation and national environmental goals. The explicit recognition of environmental effects, such as those associated with CO{sub 2} release, will result in prudent compliance plans that take advantage of current opportunities for pollution avoidance and have long-term viability in the face of regulatory change. By including such considerations, the mix of resources acquired and operated (supply and demand, existing and new, conventional and renewable, fuel type and fuel quality, pollution control, and dispatch protocols) will be robust and truly least-cost.

    Asthma, one of the most common chronic diseases in the world and a leading cause of hospitalization among children, has been associated with outdoor air pollution. We applied the wastewater-based epidemiology (WBE) approach to study the association between the use of salbutamol, a short-acting beta-agonist used to treat acute bronchospasm, and air pollution in the population of Milan, Italy. Composite 24-h samples of untreated wastewater were collected daily and analyzed for human metabolic residues of salbutamol by liquid chromatography tandem mass spectrometry. Corresponding daily outdoor concentrations of particular matter up to 10µm (PM10) and 2.5µm (PM2.5) in aerodynamic diameter, nitrogen dioxide, ozone, sulfur dioxide, and benzene were collected from the public air monitoring network. Associations at different lag times (0-10 days) were assessed by a log-linear Poisson regression model. We found significant direct associations between defined daily doses (DDD) of salbutamol and mean daily concentrations of PM10 and PM2.5 up to nine days of lag time. The highest rate ratio, and 95% confidence interval (CI), of DDD of salbutamol was 1.06 (95% CI: 1.02-1.10) and 1.07 (95% CI: 1.02-1.12) at seven days of lag time and for an increase of 10 μg/m(3) of PM10 and PM2.5, respectively. Reducing the mean daily PM10 concentration in Milan from 50 to 30μg/m(3) means that 852 (95% CI: 483-1504) daily doses of salbutamol per day would not be used. These results confirm the association between asthma and outdoor PM10 and PM2.5 and prove the potential of the WBE approach to quantitatively estimate the relation between environmental exposures and diseases.

    The Title VI Stratospheric Ozone Protection Program of the Clean Air Act (CAA) requires promulgation of regulations to reduce and prevent damage to the earth's protective ozone layer. Regulations pursuant to Title VI of the CAA are promulgated in the Code of Federal Regulations (CFR) at Title 40 CFR, Part 822. The regulations include ambitious production phaseout schedules for ozone depleting substances (ODS) including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride, and methyl chloroform under 40 CFR 82, Subpart A. The regulations also include requirements for recycling and emissions reduction during the servicing of refrigeration equipment and technician certification requirements under Subpart F; provisions for servicing of motor vehicle air conditioners under Subpart B; a ban on nonessential products containing Class 1 ODS under Subpart C; restrictions on Federal procurement of ODS under Subpart D; labeling of products using ODS under Subpart E; and the Significant New Alternatives Policy Program under Subpart G. This paper will provide details of initiatives undertaken at US Department of Energy (DOE) Oak Ridge Reservation (ORR) Facilities for implementation of requirements under the Title VI Stratospheric Ozone Protection Program. The Stratospheric Ozone Protection Plans include internal DOE requirements for: (1) maintenance of ODS inventories; (2) ODS procurement practices; (3) servicing of refrigeration and air conditioning equipment; (4) required equipment modifications or replacement; (5) technician certification training; (6) labeling of products containing ODS; (7) substitution of chlorinated solvents; and (8) replacement of halon fire protection systems. The plans also require establishment of administrative control systems which assure that compliance is achieved and maintained as the regulations continue to develop and become effective.

    Observational studies suggest that the Saharan Air Layer (SAL), an elevated layer (850-500 hPa) of Saharan air and mineral dust, has strong impacts on the microphysical as well as dynamical properties of tropical deep convective cloud systems along its track. In this case study, numerical simulations using a two-dimensional Detailed Cloud Resolving Model (DCRM) were carried out to investigate the dust-cloud interactions in the tropical deep convection, focusing on the dust role as Ice Nuclei (IN). The simulations showed that mineral dust considerably enhanced heterogeneous nucleation and freezing at temperatures warmer than -40 °C, resulting in more ice hydrometeors number concentration and reduced precipitating size of ice particles. Because of the lower in the saturation over ice as well as more droplet freezing, total latent heating increased, and consequently the updraft velocity was stronger. On the other hand, the increased ice deposition consumed more water vapor at middle troposphere, which induces a competition for water vapor between heterogeneous and homogeneous freezing and nucleation. As a result, dust suppressed the homogeneous droplet freezing and nucleation due to the heterogeneous droplet freezing and the weakened transport of water vapor at lower stratosphere, respectively. These effects led to decreased number concentration of ice cloud particles in the upper troposphere, and consequently lowered the cloud top height during the stratus precipitating stage. Acting as IN, mineral dust also influenced precipitation in deep convection. It initiated earlier the collection because dust-related heterogeneous nucleation and freezing at middle troposphere occur earlier than homogeneous nucleation at higher altitudes. Nevertheless, the convective precipitation was suppressed by reduced collection of large graupel particles and insufficient fallout related to decreased sizes of precipitating ice hydrometeors. On the contrary, dust increased the

    Section 812 of the Clean Air Act Amendments (CAAA) of 1990 requires the U.S. Environmental Protection Agency (EPA) to perform periodic, comprehensive analyses of the total costs and total benefits of programs implemented pursuant to the CAAA. The first prospective analysis was completed in 1999. The second prospective analysis was initiated during 2005. The first step in the second prospective analysis was the development of base and projection year emission estimates that will be used to generate benefit estimates of CAAA programs. This paper describes the analysis, methods, and results of the recently completed emission projections. There are several unique features of this analysis. One is the use of consistent economic assumptions from the Department of Energy's Annual Energy Outlook 2005 (AEO 2005) projections as the basis for estimating 2010 and 2020 emissions for all sectors. Another is the analysis of the different emissions paths for both with and without CAAA scenarios. Other features of this analysis include being the first EPA analysis that uses the 2002 National Emission Inventory files as the basis for making 48-state emission projections, incorporating control factor files from the Regional Planning Organizations (RPOs) that had completed emission projections at the time the analysis was performed, and modeling the emission benefits of the expected adoption of measures to meet the 8-hr ozone National Ambient Air Quality Standards (NAAQS), the Clean Air Visibility Rule, and the PM2.5 NAAQS. This analysis shows that the 1990 CAAA have produced significant reductions in criteria pollutant emissions since 1990 and that these emission reductions are expected to continue through 2020. CAAA provisions have reduced volatile organic compound (VOC) emissions by approximately 7 million t/yr by 2000, and are estimated to produce associated VOC emission reductions of 16.7 million t by 2020. Total oxides of nitrogen (NO(x)) emission reductions attributable to the

    Most analyses of utility strategies for meeting Title IV requirements in the Clean Air Act Amendments of 1990 have focused on factors relating directly to utilities` sulfur dioxide control costs; however, there are a number of additional environmental requirements that utilities must meet at the same time they comply with the acid rain program. To illuminate the potential synergies and conflicts that these other regulatory mandates may have in connection with the acid rain program, it is necessary to conduct a thorough, simultaneous examination of the various programs. This report (1) reviews the environmental mandates that utilities must plant to meet in the next decade concurrently with those of the acid rain program, (2) evaluates the technologies that utilities may select to meet these requirements, (3) reviews the impacts of public utility regulation on the acid rain program, and (4) analyzes the interactions among the various programs for potential synergies and conflicts. Generally, this report finds that the lack of coordination among current and future regulatory programs may result in higher compliance costs than necessary. Failure to take advantage of cost-effective synergies and incremental compliance planning will increase control costs and reduce environmental benefits.

    Throughout 1990 the Energy Information Administration (EIA) provided continuous data and analytic support to Congress during its deliberations on Title IV of the Clean Air Act Amendments of 1990 (CAA). Congress requested the Energy Information Administration (EIA) to review and analyze the sections that would affect electric utilities, specifically those relating to acid deposition (Title IV). By providing knowledgeable and impartial analysis, EIA clarified the likely effects of the various legislative proposals and helped Congress finalize the amendments. Even though the CAA is now law, EIA's efforts have not ended. During the analysis of the various proposals, EIA and EPA created a National Allowance Database (NAD). Now, under an agreement with the Environmental Protection Agency (EPA), a new version of the NAD is being developed to facilitate the implementation of the acid deposition provisions of the CAA. This article describes the analyses undertaken, points out where EIA's efforts led to improved understanding of the likely impacts of the CAA, and outlines EIA's continued efforts to assist EPA in the implementation of the amendments. 6 tabs.

    Objectives Asylum seekers are considered to be a particularly vulnerable group with respect to HIV. Data on the HIV prevalence among asylum seekers, however, are scarce. The aim of this study is to map the HIV prevalence among asylum seekers who gave birth in The Netherlands. Methods We used a nationwide electronic medical records database from the community health services for asylum seekers (MOA). The study population consisted of 4,854 women and girls who delivered in asylum reception between 2000 and 2008. A unique electronic health data base was used and case allocation was based on ICPC-codes. Results The number of women and girls that was HIV positive during their last pregnancy was 80, of which 79 originated from sub-Saharan Africa. The prevalence for women from this region of origin (3.4%) was high compared to women from all other regions of origin (0.04%; OR = 90.2; 95%CI 12.5–648.8). The highest HIV prevalence rates were found for women from Rwanda (17.0%) and Cameroon (13.2%). HIV prevalence rates were higher among women who arrived in reception without partner (OR = 1.82; 95%CI 0.75–4.44) and unaccompanied minors (OR = 2.59; 95%CI 0.79–8.49), compared to women who arrived in reception with partner. Conclusions We conclude that, among asylum-seeking women from sub-Saharan Africa giving birth in The Netherlands, the HIV prevalence is high compared to the host population. For women from other regions of origin, the prevalence is at the same level as in the host population. The high HIV prevalence underlines the importance of preventive interventions and voluntary HIV testing for sub-Saharan African asylum seekers as from shortly after arrival. PMID:26296093

    An accurate knowledge of the unsteady aerodynamic forces acting on a bio-inspired, flapping-wing micro air vehicle (FWMAV) is crucial in the design development and optimization cycle. Two different types of experimental approaches are often used: determination of forces from position data obtained from external optical tracking during free flight, or direct measurements of forces by attaching the FWMAV to a force transducer in a wind-tunnel. This study compares the quality of the forces obtained from both methods as applied to a 17.4 gram FWMAV capable of controlled flight. A comprehensive analysis of various error sources is performed. The effects of different factors, e.g., measurement errors, error propagation, numerical differentiation, filtering frequency selection, and structural eigenmode interference, are assessed. For the forces obtained from free flight experiments it is shown that a data acquisition frequency below 200 Hz and an accuracy in the position measurements lower than ± 0.2 mm may considerably hinder determination of the unsteady forces. In general, the force component parallel to the fuselage determined by the two methods compares well for identical flight conditions; however, a significant difference was observed for the forces along the stroke plane of the wings. This was found to originate from the restrictions applied by the clamp to the dynamic oscillations observed in free flight and from the structural resonance of the clamped FWMAV structure, which generates loads that cannot be distinguished from the external forces. Furthermore, the clamping position was found to have a pronounced influence on the eigenmodes of the structure, and this effect should be taken into account for accurate force measurements.

    Each year, Gas Research Institute (GRI) conducts an energy seminar for its Board of Directors and Advisory Council on an issue of timely importance to the gas industry. The topic selected for the Twelfth Annual GRI Energy Seminar was 'Clean Air Act Amendments of 1990: Impacts on Natural Gas Markets.' The two sessions of the seminar focused upon the sectors of the energy market most significantly affected by the legislation. Session I: Fuel Choices for Stationary Applications explored the impact of the Clean Air Act Amendments upon stationary, fuel-burning applications, particularly power plants. The current outlook for bringing existing coal-fired power plants into conformance with the law and the significance of the provisions for the choice of fuels for major future fuel-burning facilities were discussed, along with the impact of the provisions upon GRI's strategies and the technical and economic targets for ongoing R and D. Session II: The Emerging Alternative-Fuel Vehicle Market addressed the significance of the new requirements to the outlook for compressed natural gas vehicles and the suitability of GRI's methane vehicle R and D strategy to the revised outlook. The report summarizes the presentations and discussions at the seminar.

  5. Environmental health and safety issues related to the use of low-level radioactive waste (LLRW) at hospitals and medical research institutions and compliance determination with the Clean Air Act standards

    SciTech Connect

    Kasinathan, R.; Kanchan, A.

    1995-12-31

    Currently, the United States Nuclear Regulatory Commission (NRC) has standards for procedures, performance activities and technical specifications on storage of Low-Level Radioactive Waste (LLRW) under 10 CFR Part 20. The United States Environmental Protection Agency (EPA) is proposing environmental standards for the management, storage and disposal of LLRW. The proposed standards, which will become 40 CFR part 193 when finalized, limits the committed effective dose to members of the public from the management and storage of LLRW, committed effective doses resulting from LLRW disposal and levels of radiological contamination of underground sources of drinking water as a result of the activities subject to management, storage and disposal of LLRW. Further, under Title III of the Clean Air Act Amendments, radionuclides are required to be inventoried for all generators. For hospitals and medical research institutions, quantities of LLRW are often below the concentrations required under reporting and record keeping requirements of 10 CFR 20. However, in many instances, the facility may require NRC permits and compliance with air quality dispersion modeling requirements. This paper presents the typical radionuclides used in hospitals and medical research institutions, and strategies to evaluate their usage and steps to achieve compliance. Air quality dispersion modeling by use of the COMPLY model is demonstrated to evaluate the fate of radionuclides released from on-site incineration of LLRW. The paper concludes that no significant threat is posed from the incineration of LLRW.

    The authors report two cases of adenocarcinoma of the lung in which Tl-201 gave a better delineation of metastatic lesions than did Ga-67. In the case of multiple bone metastases, the metastatic lesion of the skull was clearly demonstrated by Tl-201 but not by Ga-67. In another case of multiple brain metastases, the lesions were also visualized by Tl-201 but not by Ga-67. Tl-201 is occasionally superior to Ga-67 for visualizing metastatic adenocarcinoma of the lung.

  7. Emission projections for the U.S. Environmental Protection Agency Section 812 Second Prospective Clean Air Act cost/benefit analysis

    James H. Wilson, Jr.; Maureen A. Mullen; Andrew D. Bollman

    2008-05-15

    This paper describes the analysis, methods, and results of the recently completed emission projections. There are several unique features of this analysis. One is the use of consistent economic assumptions from the Department of Energy's Annual Energy Outlook 2005 (AEO 2005) projections as the basis for estimating 2010 and 2020 emissions for all sectors. Another is the analysis of the different emissions paths for both with and without CAAA scenarios. Other features of this analysis include being the first EPA analysis that uses the 2002 National Emission Inventory files as the basis for making 48-state emission projections, incorporating control factor files from the Regional Planning Organizations (RPOs) that had completed emission projections at the time the analysis was performed, and modeling the emission benefits of the expected adoption of measures to meet the 8-hr ozone National Ambient Air Quality Standards (NAAQS), the Clean Air Visibility Rule, and the PM2.5 NAAQS. This analysis shows that the 1990 CAAA have produced significant reductions in criteria pollutant emissions since 1990 and that these emission reductions are expected to continue through 2020. CAAA provisions have reduced volatile organic compound (VOC) emissions by approximately 7 million t/yr by 2000, and are estimated to produce associated VOC emission reductions of 16.7 million t by 2020. Total oxides of nitrogen (NOx) emission reductions attributable to the CAAA are 5, 12, and 17 million t in 2000, 2010, and 2020, respectively. Sulfur dioxide (SO{sub 2}) emission benefits during the study period are dominated by electricity-generating unit (EGU) SO{sub 2} emission reductions. These EGU emission benefits go from 7.5 million t reduced in 2000 to 15 million t reduced in 2020. 16 refs., 6 figs., 13 tabs.

    We aimed to compare the protective effect of single doses of 4.5 and 9 microg of formoterol fumarate (F), 0.5 mg terbutaline sulphate (T) and placebo (P), all via Turbuhaler, against exercise-induced bronchoconstriction (EIB) in children. Twenty-seven asthmatic children, showing a fall of > or =20% in FEV1 after a standardized exercise challenge test (ECT) combined with cold air (-10 degrees C) inhalation, were randomized in this cross-over, double-blind study. They had a mean age of 12.6 years (range 8-17 years), mean baseline FEV1 90% (73.9-105.6%) of predicted normal value. Seventeen children used inhaled glucocorticosteroids (120-750 microg day(-1)). ECTs were performed 15 min and 4, 8, and 12 h after drug administration. F significantly reduced the fall in FEV1 after ECT to 5.4% (15 min), 5.2% (4 h), 8.2% (8 h) and 9.3% (12 h) after 4.5 microg, and 2.5%, 3.0%, 5.0% and 5.4% after 9 microg, compared with a fall of 18.4%, 15.7%, 15.6% and 16.5% in FEV1 after P. The fall after T was 3.3%, 11.6%, 14.4% and 19.1% after 15 min, 4, 8 and 12 h respectively. The difference between F and T was statistically significant from 4 h and onward (P-value for all comparisons < 0.05). Children using a single dose of either formoterol Turbuhaler 4.5 or 9 microg had significantly better bronchoprotection against repeated exercise challenge up to 12 h compared with placebo and from 4 h onward compared with terbutaline Turbuhaler 0.5 mg.

    Two new methods for assessing temporal trends in stream-solute concentrations at specific streamflow ranges were applied to long (40 to 50-year) but sparse (bi-weekly to quarterly sampling) stream-water quality data collected at three forested mesoscale basins along an atmospheric deposition gradient in the northeastern United States (one in north-central Pennsylvania, one in southeastern New York, and one in eastern Maine). The three data sets span the period since the implementation of the Clean Air Act in 1970 and its subsequent amendments. Declining sulfate (O4(2-)) trends since the mid 1960s were identified for all 3 rivers by one or more of the 4 methods of trend detection used. Flow-specific trends were assessed by segmenting the data sets into 3-year and 6-year blocks, then determining concentration-discharge relationships for each block. Declining sulfate (O4(2-)) trends at median flow were similar to trends determined using a Seasonal Kendall Tau test and Sen slope estimator. The trend of declining O4(2-) concentrations differed at high, median and low flow since the mid 1980s at YWC and NR, and at high and low flow at WR, but the trends leveled or reversed at high flow from 1999 through 2002. Trends for the period of record at high flows were similar to medium- and low-flow trends for Ca2++ Mg2+ concentrations at WR, non-significant at YWC, and were more negative at low flow than at high flow at NR; trends in nitrate (NO3-), and alkalinity (ALK) concentrations were different at different flow conditions, and in ways that are consistent with the hydrology and deposition history at each watershed. Quarterly sampling is adequate for assessing average-flow trends in the chemical parameters assessed over long time periods (approximately decades). However, with even a modest effort at sampling a range of flow conditions within each year, trends at specified flows for constituents with strong concentration-discharge relationships can be evaluated and may allow

    This chapter looks at how in the 1960's the laboratory worked to broaden the base of its work. The laboratory began its mission by developing nuclear energy for wartime usage, expanded into nuclear energy, and into broader peaceful application of nuclear energy, but in the late 50's was still primarily based on nuclear physics, or closely related disciplines. Because of problems encountered by several large scale programs, management began to look at broadening the scope of the laboratory, to provide a base not entirely based on nuclear physics, and to take advantage of the caliber of intellectual strengths within the laboratory personnel. Projects which were developed included enhanced work in information sciences, related to analyzing and making available the vast amount of published literature appearing in print. Efforts were directed toward desalination programs, and expanded work in large biology projects. Work was expanded into DNA projects, and cancer research on smoking. Efforts went into civil defense issues. There was an expanded effort to study environmental concerns, from water to air to ground. Nuclear safety issues became an increasingly larger segment of the reactor programs. The laboratory had 14% of it programs consisting of non-nuclear work for agencies other than AEC by 1969, and in general this had been achieved by approaching AEC on these programs one at a time. The lab had developed a much broader program than most other national labs at this time.

    Attendees have reported changing from being fearful to serene, from listless to energized, from disengaged to connected, and becoming markedly less anxious in a few weeks. Anecdotally, self-reported stress levels have been reduced by over 50% after just one class. Attendees learn not to be afraid of their feelings by working with emotions in a playful manner. When a person can act angry, but separate himself from his personal story, the emotional energy exists in a separate form that is not attached to specific events, and can be more easily dealt with and neutralized. Attendees are taught to "take out the emotional trash" through expressive comedy. They become less intimated by their own emotional intensity and triggers as they learn how even metaphorical buckets of anger, shame, guilt and hurt can be emotionally emptied. The added benefit is that this is accomplished without the disclosure of personal information of the requirement to reexperience past pain which can trigger its own cascade of stress. PMID:24706248

    A high-current, fast-acting switch is designed for utilization as a crowbar switch in a high-current circuit such as used to generate the magnetic confinement field of a plasma-confining and heat device, e.g., Pyrotron. The device particularly comprises a cylindrical housing containing two stationary, cylindrical contacts between which a movable contact is bridged to close the switch. The movable contact is actuated by a differential-pressure, airdriven piston assembly also within the housing. To absorb the acceleration (and the shock imparted to the device by the rapidly driven, movable contact), an adjustable air buffer assembly is provided, integrally connected to the movable contact and piston assembly. Various safety locks and circuit-synchronizing means are also provided to permit proper cooperation of the invention and the high-current circuit in which it is installed. (AEC)

The seals featured Rayleigh step pads (self-acting geometry) for lift augmentation. The tested seals incorporated design improvements over previous self-acting configurations. Self-acting face seals were tested to speeds of 214 m/s (700 ft/sec, 63700 rpm), air pressures of 216.8 N/sq cm abs (314.7 psia), and air temperatures of 688K (778 F). Self-acting circumferential seals were tested to speeds of 183 m/s (600 ft/sec, 47700 rpm), air pressures of 61.8 N/sq cm abs (89.7 psia), and air temperatures of 711 K (820 F). Self-acting face-seals are capable of operating at conditions exceeding conventional seal capability. The limit on speed capability was found to be the flatness of the seal-seat. The self-acting circumferential seal design tested requires further development for use in advanced engines.

  4. ACTS broadband aeronautical experiment

    NASA Technical Reports Server (NTRS)

    Abbe, Brian S.; Jedrey, Thomas C.; Estabrook, Polly; Agan, Martin J.

    1993-01-01

    In the last decade, the demand for reliable data, voice, and video satellite communication links between aircraft and ground to improve air traffic control, airline management, and to meet the growing demand for passenger communications has increased significantly. It is expected that in the near future, the spectrum required for aeronautical communication services will grow significantly beyond that currently available at L-band. In anticipation of this, JPL is developing an experimental broadband aeronautical satellite communications system that will utilize NASA's Advanced Communications Technology Satellite (ACTS) as a satellite of opportunity and the technology developed under JPL's ACTS Mobile Terminal (AMT) Task to evaluate the feasibility of using K/Ka-band for these applications. The application of K/Ka-band for aeronautical satellite communications at cruise altitudes is particularly promising for several reasons: (1) the minimal amount of signal attenuation due to rain; (2) the reduced drag due to the smaller K/Ka-band antennas (as compared to the current L-band systems); and (3) the large amount of available bandwidth. The increased bandwidth available at these frequencies is expected to lead to significantly improved passenger communications - including full-duplex compressed video and multiple channel voice. A description of the proposed broadband experimental system will be presented including: (1) applications of K/Ka-band aeronautical satellite technology to U.S. industry; (2) the experiment objectives; (3) the experiment set-up; (4) experimental equipment description; and (5) industrial participation in the experiment and the benefits.

  7. Fluorescence light microscopy of pulmonary surfactant at the air-water interface of an air bubble of adjustable size.

    2002-07-01

    The structural dynamics of pulmonary surfactant was studied by epifluorescence light microscopy at the air-water interface of a bubble as a model close to nature for an alveolus. Small unilamellar vesicles of dipalmitoylphosphatidylcholine, dipalmitoylphosphatidylglycerol, a small amount of a fluorescent dipalmitoylphosphatidylcholine-analog, and surfactant-associated protein C were injected into the buffer solution. They aggregated to large clusters in the presence of Ca(2+) and adsorbed from these units to the interface. This gave rise to an interfacial film that eventually became fully condensed with dark, polygonal domains in a fluorescent matrix. When now the bubble size was increased or decreased, respectively, the film expanded or contracted. Upon expansion of the bubble, the dark areas became larger to the debit of the bright matrix and reversed upon contraction. We were able to observe single domains during the whole process. The film remained condensed, even when the interface was increased to twice its original size. From comparison with scanning force microscopy directly at the air-water interface, the fluorescent areas proved to be lipid bilayers associated with the (dark) monolayer. In the lung, such multilayer phase acts as a reservoir that guarantees a full molecular coverage of the alveolar interface during the breathing cycle and provides mechanical stability to the film.

    This section describes the ambient (surrounding) air quality of the TVA region, discusses TVA emission contributions to ambient air quality, and identifies air quality impacts to human health and welfare. Volume 2 Technical Document 2, Environmental Consequences, describes how changes in TVA emissions could affect regional air quality, human health, environmental resources, and materials. The primary region of the affected environment is broadly defined as the state of Tennessee, as well as southern Kentucky, western Virginia, southern West Virginia, western North Carolina, and northern Georgia, Alabama, and Mississippi. This area represents the watershed of the Tennessee River and the 201 counties of the greater TVA service area. Emissions from outside the Tennessee Valley region contribute to air quality in the Valley. Also, TVA emissions are transported outside the Valley and have some impact on air quality beyond the primary study area. Although the study area experiences a number of air quality problems, overall air quality is good.

    The effect of a nanosecond volume discharge forming in an inhomogeneous electrical field at atmospheric pressure on the CdHgTe (MCT) epitaxial films of the p-type conduction with the hole concentration 2·1016 cm3 and mobility 500 cm2·V-1·s-1 is studied. The measurement of the electrophysical parameters of the MCT specimens upon irradiation shows that a layer exhibiting the n-type conduction is formed in the near-surface region of the epitaxial films. After 600 pulses and more, the thickness and the parameters of the layer are such that the measured field dependence of the Hall coefficient corresponds to the material of the n-type conduction. Analysis of the preliminary results reveals that the foregoing nanosecond volume discharge in the air at atmospheric pressure is promising for modification of electro-physical MCT properties.

    Raquet, Charles A. (Compiler); Martzaklis, Konstantinos (Compiler); Zakrajsek, Robert J. (Compiler); Andro, Monty (Compiler); Turtle, John P.

    1996-01-01

    Over a one year period from May 1994 to May 1995, a number of demonstrations were conducted by the NASA Lewis Research Center (LeRC) in which voice, data, and/or video links were established via NASA's advanced communications technology satellite (ACTS) between the ACTS link evaluation terminal (LET) in Cleveland, OH, and aeronautical and mobile or fixed Earth terminals having monolithic microwave integrated circuit (MMIC) phased array antenna systems. This paper describes four of these. In one, a duplex voice link between an aeronautical terminal on the LeRC Learjet and the ACTS was achieved. Two others demonstrated duplex voice (and in one case video as well) links between the ACTS and an Army vehicle. The fourth demonstrated a high data rate downlink from ACTS to a fixed terminal. Array antenna systems used in these demonstrations were developed by LeRC and featured LeRC and Air Force experimental arrays using gallium arsenide MMIC devices at each radiating element for electronic beam steering and distributed power amplification. The single 30 GHz transmit array was developed by NASA/LeRC and Texas Instruments. The three 20 GHz receive arrays were developed in a cooperative effort with the Air Force Rome Laboratory, taking advantage of existing Air Force array development contracts with Boeing and Lockheed Martin. The paper describes the four proof-of-concept arrays and the array control system. The system configured for each of the demonstrations is described, and results are discussed.

    1988-01-01

    S.2720 regulates any fleet of automobiles or light-duty trucks owned or leased by the US for operation in any area designated under the Clean Air Act as an area of serious or severe health endangerment for ozone or carbon monoxide. As of September 30, 1993, 10% of such vehicles are required to be alternative fuel vehicles. The percentage increases 10% each year until September 30, 2001, at which time 100% of such vehicles should be alternative fuel vehicles. The bill provides extra funding for the purchase of alternative fuel vehicles as needed, but will pay only the portion of the cost which exceeds the cost of comparable conventionally fueled vehicles. The bill also requires gasoline-powered vehicles in the designated areas to be supplied with fuel which blends oxygenates with the gasoline at its primary fueling facility, as of March 31, 1989.

  17. Aerodynamical sealing by air curtains

    NASA Astrophysics Data System (ADS)

    Frank, Daria; Linden, Paul

    2015-11-01

    Air curtains are artificial high-velocity plane turbulent jets which are installed in a doorway in order to reduce the heat and the mass exchange between two environments. The performance of an air curtain is assessed in terms of the sealing effectiveness E, the fraction of the exchange flow prevented by the air curtain compared to the open-door situation. The main controlling parameter for air curtain dynamics is the deflection modulus Dm representing the ratio of the momentum flux of the air curtain and the transverse forces acting on it due to the stack effect. In this talk, we examine the influence of two factors on the performance of an air curtain: the presence of an additional ventilation pathway in the room, such as a small top opening, and the effects of an opposing buoyancy force which for example arises if a downwards blowing air curtain is heated. Small-scale experiments were conducted to investigate the E (Dm) -curve of an air curtain in both situations. We present both experimental results and theoretical explanations for our observations. We also briefly illustrate how simplified models developed for air curtains can be used for more complex phenomena such as the effects of wind blowing around a model building on the ventilation rates through the openings.
