  1. Diffusion of clean indoor air ordinances in the southwestern United States.

    PubMed

    Rogers, Everett M; Peterson, Jeffery C

    2008-10-01

    The authors investigate the process through which clean indoor air ordinances were considered in 10 communities in the southwestern United States and key factors that influenced diffusion and adoption. Clean indoor air ordinances, which ban smoking in public places, were adopted in approximately 1,409 U.S. communities from 1986 to April 2004. The authors gathered data from 10 communities in New Mexico and Texas by means of face-to-face interview, e-mail, and telephone interviews and by analyzing archival materials. Important influences on the adoption or rejection of clean indoor air ordinances were (a) personal experiences of policy champions, (b) local framing of the ordinance as a public health issue versus as an economic/ business or an individual rights issue, and (c) interpersonal networks connecting a community to previously adopting communities. The policies that were adopted ranged in comprehensiveness, with each community of study reinventing model policies obtained from other communities.

    The submission explores the possibility of a policy revision for considering clean air quality in recently launched nationwide campaign, Clean India Mission (CIM). Despite of several efforts for improving availability of clean household energy and sanitation facilities, situation remain still depressing as almost half of global population lacks access to clean energy and proper sanitation. Globally, at least 2.5 billion people do not have access to basic sanitation facilities. There are also evidences of 7 million premature deaths by air pollution in year 2012. The situation is even more disastrous for India especially in rural areas. Although, India has reasonably progressed in developing sanitary facilities and disseminating clean fuel to its urban households, the situation in rural areas is still miserable and needs to be reviewed. Several policy interventions and campaigns were made to improve the scenario but outcomes were remarkably poor. Indian census revealed a mere 31% sanitation coverage (in 2011) compared to 22% in 2001 while 60% of population (700 million) still use solid biofuels and traditional cook stoves for household cooking. Further, last decade (2001-2011) witnessed the progress decelerating down with rural households without sanitation facilities increased by 8.3 million while minimum progress has been made in conversion of conventional to modern fuels. To revamp the sanitation coverage, an overambitious nationwide campaign CIM was initiated in 2014 and present submission explores the possibility of including 'clean air' considerations within it. The article draws evidence from literatures on scenarios of rural sanitation, energy practises, pollution induced mortality and climatic impacts of air pollution. This subsequently hypothesised with possible modification in available technologies, dissemination modes, financing and implementation for integration of CIM with 'clean air' so that access to both sanitation and clean household energy may be

    2005-01-01

    Executive Summary Objective This health technology policy assessment will answer the following questions: When should in-room air cleaners be used? How effective are in-room air cleaners? Are in-room air cleaners that use combined HEPA and UVGI air cleaning technology more effective than those that use HEPA filtration alone? What is the Plasmacluster ion air purifier in the pandemic influenza preparation plan? The experience of severe acute respiratory syndrome (SARS) locally, nationally, and internationally underscored the importance of administrative, environmental, and personal protective infection control measures in health care facilities. In the aftermath of the SARS crisis, there was a need for a clearer understanding of Ontario’s capacity to manage suspected or confirmed cases of airborne infectious diseases. In so doing, the Walker Commission thought that more attention should be paid to the potential use of new technologies such as in-room air cleaning units. It recommended that the Medical Advisory Secretariat of the Ontario Ministry of Health and Long-Term Care evaluate the appropriate use and effectiveness of such new technologies. Accordingly, the Ontario Health Technology Advisory Committee asked the Medical Advisory Secretariat to review the literature on the effectiveness and utility of in-room air cleaners that use high-efficiency particle air (HEPA) filters and ultraviolet germicidal irradiation (UVGI) air cleaning technology. Additionally, the Ontario Health Technology Advisory Committee prioritized a request from the ministry’s Emergency Management Unit to investigate the possible role of the Plasmacluster ion air purifier manufactured by Sharp Electronics Corporation, in the pandemic influenza preparation plan. Clinical Need Airborne transmission of infectious diseases depends in part on the concentration of breathable infectious pathogens (germs) in room air. Infection control is achieved by a combination of administrative, engineering

    Designing Air Cleaning Units (ACU) of an Engineered Safety Feature and normal atmosphere clean-up system at the renovated APR-1000 and APR-1400 NPP, and fuel cycle facilities in Korea, is required to meet the standards of ASME AG-1 (1997), ASME N509/N510 (1989) and KEPIC-MH (2001) to enhance the removal efficiency of aerosols and particulates from the effluents. The revised ACU testing criteria are allowed to use alternative challenge agents of the dioctyl phthalate and Refrigerant-11 for in situ testing of high efficiency particulate air filters and adsorption banks. The operability testing time of engineered safety feature (ESF) trains was changed from 10 h to 15 min. The activated carbon in adsorption banks should undergo laboratory tests at a temperature of 30 °C and relative humidity 95 %. The removal criteria of methyl iodide should be over 99.5 % for ESF and 99 % for normal systems. This paper provides the background of the changed criteria for designing and testing of the ACU system in nuclear facilities.

    In this article, we present the results of a systematic review of state, county, and municipal restrictions on the use of electronic cigarettes (e-cigarettes) in public spaces within the United States, alongside an overview of the current legal landscape. The lack of federal guidance leaves lower-level jurisdictions to debate the merits of restrictions on use in public spaces without sufficient scientific research. As we show through a geographic assessment of restrictions, this has resulted in an inconsistent patchwork of e-cigarette use bans across the United States of varying degrees of coverage. Bans have emerged over time in a manner that suggests a "bottom up" diffusion of e-cigarette clean air policies. Ultimately, the lack of clinical and scientific knowledge on the risks and potential harm reduction benefits has led to precautionary policymaking, which often lacks grounding in empirical evidence and results in spatially uneven diffusion of policy.

    We evaluated air cleaning as a means to mitigate risks arising from exposure to indoor radon progeny in several single-family houses in the northeastern United States, using a new, automated, semi-continuous activity-weighted size distribution measurement system. Measurements included radon concentration, condensation nuclei count, and activity-weighted size distribution of radon decay products. Measurements were made with and without the air cleaning system operating. The influence of particles generated by various sources common to normal indoor activities on radon progeny behavior was evaluated. Aerosols were generated by running water in a shower, burning candles, smoking cigarettes, vacuuming, opening doors, and cooking. Both a filtration unit and an electrostatic precipitator were evaluated. Using a room model, the changes in attachment rates, average attachment diameters, and deposition rates of the ``unattached`` fraction with and without the air cleaning systems were calculated. The air cleaner typically reduced the radon progeny concentrations by 50 to 60%.

  7. What is an effective portable air cleaning device? A review.

    2006-04-01

    The use of portable air cleaning devices in residential settings has been steadily growing over the last 10 years. Three out of every 10 households now contain a portable air cleaning device. This increased use of air cleaners is accompanied by, if not influenced by, a fundamental belief by consumers that the air cleaners are providing an improved indoor air environment. However, there is a wide variation in the performance of air cleaners that is dependent on the specific air cleaner design and various indoor factors. The most widely used method in the United States to assess the performance of new air cleaners is the procedure described in the American National Standards Institute (ANSI)/Association of Home Appliance Manufacturers (AHAM) AC-1-2002. This method describes both the test conditions and the testing protocol. The protocol yields a performance metric that is based on the measured decay rate of contaminant concentrations with the air cleaner operating compared with the measured decay rate with the air cleaner turned off. The resulting metric, the clean air delivery rate (CADR), permits both an intercomparison of performance among various air cleaners and a comparison of air cleaner operation to other contaminant removal processes. In this article, we comment on the testing process, discuss its applicability to various contaminants, and evaluate the resulting performance metrics for effective air cleaning.

  8. The economic impact of clean indoor air laws.

    2007-01-01

    Clean indoor air laws are easily implemented, are well accepted by the public, reduce nonsmoker exposure to secondhand smoke, and contribute to a reduction in overall cigarette consumption. There are currently thousands of clean indoor air laws throughout the Unites States, and the majority of Americans live in areas where smoking is completely prohibited in workplaces, restaurants, or bars. The vast majority of scientific evidence indicates that there is no negative economic impact of clean indoor air policies, with many studies finding that there may be some positive effects on local businesses. This is despite the fact that tobacco industry-sponsored research has attempted to create fears to the contrary. Further progress in the diffusion of clean indoor air laws will depend on the continued documentation of the economic impact of clean indoor air laws, particularly within the hospitality industry. This article reviews the spread of clean indoor air laws, the effect on public health, and the scientific evidence of the economic impact of implementation of clean indoor air laws.

  9. The Value of Clean Air

    NASA Astrophysics Data System (ADS)

    Shindell, D. T.

    2014-12-01

    How can society place a value on clean air? I present a multi-impact economic valuation framework called the Social Cost of Atmospheric Release (SCAR) that extends the Social Cost of Carbon (SCC) used previously for carbon dioxide (CO2) to a broader range of pollutants and impacts. Values consistently incorporate health impacts of air quality along with climate damages. The latter include damages associated with aerosol-induced hydrologic cycle changes that lead to net climate benefits when reducing cooling aerosols. Evaluating a 1% reduction in current global emissions, benefits with a high discount rate are greatest for reductions of co-emitted products of incomplete combustion (PIC), followed by sulfur dioxide (SO2), nitrogen oxides (NOx) and then CO2, ammonia and methane. With a low discount rate, benefits are greatest for CO2 reductions, though the sum of SO2, PIC and methane is substantially larger. These results suggest that efforts to mitigate atmosphere-related environmental damages should target a broad set of emissions including CO2, methane and aerosol/ozone precursors. Illustrative calculations indicate environmental damages are 410-1100 billion yr-1 for current US electricity generation ( 19-46¢ per kWh for coal, 4-24¢ for gas) and 3.80 (-1.80/+2.10) per gallon of gasoline ($4.80 (-3.10/+3.50) per gallon for diesel). These results suggest that total atmosphere-related environmental damages plus generation costs are much greater for coal-fired power than other types of electricity generation, and that damages associated with gasoline vehicles substantially exceed those for electric vehicles.

    Hobbs, Peter V.

    2002-01-01

    Layering in the Earth's atmosphere is most commonly seen where parts of the atmosphere resist the incursion of air parcels from above and below - for example, when there is an increase in temperature with height over a particular altitude range. Pollutants tend to accumulate underneath the resulting stable layers. which is why visibility often increases markedly above certain altitudes. Here we describe the occurrence of an opposite effect, in which stable layers generate a layer of remarkably clean air (we refer to these layers as clean-air 'slots') sandwiched between layers of polluted air. We have observed clean-air slots in various locations around the world, but they are particularly well defined and prevalent in southern Africa during the dry season August-September). This is because at this time in this region, stable layers are common and pollution from biomass burning is widespread.

    The secondary side of the Byron Nuclear Station, Unit 1 steam generators were successfully chemically cleaned in September 1994, using the BWNT/Framatome high-temperature chemical cleaning process. This cleaning was the first North American application that used plant heat for process temperature control. The primary purpose of the cleaning was to remove bulk deposits and deposits from the drilled tube-to-tube support plate crevices of the Westinghouse D4 steam generators. Crevice deposit removal was targeted to mitigate initiation of new corrosion defects and the propagation of existing defects. The process application scenario and plant interface equipment were designed to maximize effectiveness while minimizing corrosion, waste volumes, and critical path time. A total of over 15,383 pounds (6,992 kilograms) of material was removed from the four steam generators during the chemical cleaning. Post-cleaning visual inspections showed the steam generators to be very clean. Some quantity (30% to 60%) of deposits remained in crevice areas. One indication of successful crevice magnetite removal was very clean and crisp eddy-current signals in the tube support plate region. Corrosion to steam generator materials resulting from the cleaning was less than 2.5 mils (63.5 {micro}m) and consumed less than 20% of the available corrosion allowance.

    Major conclusions and recommendations of the National Commission on Air Quality on issues of health in the Clean Air Act are presented. The issues revolve mainly about the standard setting processes for ubiquitous pollutants, controlled through ambient air quality standards (Section 109), and for hazardous pollutants controlled through emission standards (Section 112). The conceptual difficulties inherent in the terms "adequate margin of safety" (Section 109) and "ample margin of safety" (Section 112) are discussed. The Clean Air Science Advisory Committee is widely viewed as having a salutary effect on standard setting. The need for maintaining strong research capabilities within the Environmental Protection Agency that are reasonably buffered against sudden disruptive events is emphasized. Mechanisms for achieving this goal through special congressional appropriations are considered. PMID:6653527

    This dissertation looks at the relationship between American subnational governments and clean air policy in three different cases. I investigate the impact of state reduction policies on the emission of Greenhouse emissions, the subnational adoption of Greenhouse Gas tracking and reduction policies, and the impact of Clean Air Act standards on the siting of coal-fired power plants. The major finding is that in both the adoption and business response to these policies, a state's political context can limit its ability to regulate air pollution. These factors contribute to the unequal protection of air quality across the United States.

    Clean indoor air policies are an effective way to eliminate exposure to second hand smoke and reduce smoking among youth and adults; they are strongly recommended by the Surgeon General and the Task Force on Community Preventive Services. How these policies are put into effect and at what level of government can make a difference. Legislation that preempts local action prevents communities from enacting more stringent laws or tailoring laws to address community-specific issues. Preemptive state laws also can be a barrier to local enforcement because communities not involved in decision making may be less aware of laws, may have no enforcement mechanism, and thus may be less complaint. Preemption is clearly a tobacco industry strategy to take away local control, usually in exchange for a weak law offering little protection from second hand smoke. As communities across the country continue to pass stronger local ordinances, eliminating preemptive laws becomes more important. During 2002, Delaware became the first state to repeal clean air preemption. In Iowa, the attorney general's office has been involved in the determination of whether the state clean air law prevents communities from passing more stringent ordinances. And although Minnesota's pioneer Clean Indoor Air Act does not preempt local laws, the debate over preemption there has not ended but instead has taken new forms.

  9. Carbon adsorption for indoor air cleaning

    SciTech Connect

    VanOsdell, D.W.; Sparks, L.E.

    1995-02-01

    Gas-phase air filtration equipment (GPAFE) has been applied for many years to control industrial gaseous contaminants. Interest in cleaning recirculation air to provide ventilation without the need to condition excessive outdoor air has promoted increased interest in GPAFE as indoor air control devices. The removal of volatile organic compounds (VOCs) using granular activated carbon (GAC) is the focus of this article. First, the authors present performance measurements for GAC at low challenge VOC concentrations that might be encountered indoors. Unlike previously reported tests, these were continued long enough to directly determine the GAC`s expected lifetime. The results suggest that test results obtained at high challenge concentrations may be extrapolated to low, indoor concentrations. Further study is needed, but these data are encouraging. Second, they will discuss the implications of these performance measurements for the use of GAC to remove VOCs and improve indoor air quality (IAQ) using an indoor air building simulation model.

  14. EPA`s clean air power initiative

    Critchfield, L.R.

    1997-12-31

    The Clean Air Power Initiative (CAPI) is a multi-stakeholder project intended to improve air pollution control efforts involving the power generating industry. This paper documents the progress made in the first year of the initiative, which included a number of meetings with interested stakeholders and development and analysis of alternative approaches for more efficient and effective pollution control. The project`s goal is to develop an integrated regulatory strategy or three major pollutants emitted from electric power generators; namely, sulfur dioxide, nitrogen oxides, and, potentially, mercury. Major reductions in these pollutants are expected to be needed to reduce the detrimental health effects of ground-level ozone, fine particles, and hazardous air pollutants and reduce the environmental effects of acidification, eutrophication, ecosystem, crop, and materials damage, and regional haze. The Clean Air Power Initiative has considered, where feasible, new approaches to pollution control that recognize the long-range transport of many air pollutants and the economic benefits of emissions trading. The project was initiated by EPA`s Assistant Administrator for Air and Radiation in 1995. As individual companies develop and implement strategies to participate in more competitive power markets, they could benefit from greater certainty in being able to plan for and reduce costs of future environmental regulations. The EPA is interested in reinventing its regulatory approach to reduce the number, administrative complexity, and cost of its requirements while improving the likelihood of achieving environmental results.

  3. Proposed Clean Air Act reform draws fire

    NASA Astrophysics Data System (ADS)

    Showstack, Randy

    A Congressional hearing on the accomplishments of the U.S. Clean Air Act and subsequent amendments turned into a squabble about whether Bush administration efforts to reform the act would improve or undermine air quality regulations.At the 1 May hearing of the House of Representatives' Subcommittee on Energy and Air Quality, a key sticking point concerned whether an emissions "cap-and-trade" program, which was proposed as part of President George W. Bush's 14 February Clear Skies initiative, would effectively meet air quality standards. The program would provide market-based incentives to reduce emissions of sulfur dioxide, nitrogen oxides, and mercury. Another point of contention was whether such a program would make some current regulations, including new source review of upgraded utility plants, redundant and unnecessary.

    2009-01-01

    This investigation sought to examine the association between knowledge of the risks associated with environmental tobacco smoke and voter support for clean indoor air policies. In doing so, 2 antecedents were employed to enhance understanding of this relationship: attitudes and subjective norms. In addition, differences between nonsmokers and smokers were assessed across the aforementioned variables. The study sampled participants (N = 550) living in the Appalachian foothills as a means of conducting formative research prior to developing messages promoting clean indoor air policies. The study controlled for tobacco usage, age, biological sex, and income. Results revealed that awareness of risk is a good predictor of attitudes and social norms, and in return, attitudes and social norms are good predictors of support for clean indoor air policies. In addition, results reveal that nonsmokers maintain a significantly stronger belief in the dangers associated with environmental tobacco smoke, as well as more favorable attitudes, subjective norms, and support for clean indoor air policies when compared with smokers. These findings are discussed with a focus on message design strategies for practitioners and academics with interests in promoting clean indoor air policies.

    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.

The literature on air cleaning systems is reviewed to identify potential air cleaning alternatives that might be included in the design of HWVP. An overview of advantages/disadvantages of the various air cleaning technologies follows. Information and references are presented for the following potential air cleaning alternatives: deep-bed glass-fiber filters (DBGF), high-efficiency particulate air filters (HEPA), remote modular filter systems, high-efficiency mist eliminators (HEME), electrostatic precipitators, and the sand filter. Selected information is summarized for systems in the United States, Belgium, Japan, and West Germany. This review addresses high-capacity air cleaning systems currently used in the nuclear industry and emphasizes recent developments. 10 refs., 9 figs., 3 tabs.

    2002-11-01

    A laboratory pilot study has been undertaken with the material that showed the most promise (high capacity and low pressure drop) based on the literature review and associated calculations. The best-performing air cleaner was a commercially available pleated filter that contained a thin layer of small activated carbon particles between two sheets of non-woven fibrous webbing. We will refer to this unit as the ''ozone filter'' although it is marketed for removal of volatile organic compounds (VOCs) from automobile passenger compartments. This pilot study strongly suggests that ozone air cleaning can be practical in commercial air handling systems; however, further tests are needed to assess air cleaner performance under a wider range of conditions.

EPA the five of the eight plants violated CAA rules requiring refineries to install and operate continuous emission monitoring systems (CEMs). CEMs are installed to measure either the concentration of hydrogen sulfide in fuel gases before they are burned or the amount of sulfur dioxide emitted after burning. The deadline for installing CEMs was Oct. 2, 1991. In addition, seven of the plants are accused of failure to submit semiannual reports to EPA on whether excess emissions were measured by CEMs, as required by the CAA.

  3. Identification of Candidate Clean Air Corridors for the Colorado Plateau.

    PubMed

    1996-05-01

    The U.S. Clean Air Act, amended in 1990, mandated the establishment of the Grand Canyon Visibility Transport Commission (GCVTC). The commission is required to submit a report to the U.S. Environmental Protection Agency addressing visibility issues in the region, including "the establishment of clean air corridors, in which additional restrictions on increases in emissions may be appropriate to protect visibility in affected Class I areas." This paper presents a methodology to identify candidate geographic areas for consideration for Clean Air Corridor (CAC) status for Colorado Plateau Class I areas. The methodology uses thousands of model determined trajectories over a five year period (1988 to 1992) to indicate the paths taken by air that arrives during clean air conditions at Class I areas. These clean air back-trajectories identify upwind areas where pollution emissions could jeopardize currently pristine visibility. Using this methodology, six candidate areas are identified, ranging in size from 75,000 to 506,000 square miles, and permitting varying levels of visibility protection for clean air days at Grand Canyon, Canyonlands, and Petrified Forest National Parks. Assuming effective emissions management of the CAC, the larger the CAC, the greater the visibility protection during clean air conditions.

  4. Air cleaning issues with contaminated sites

    SciTech Connect

    Bellamy, R.R.

    1997-08-01

    The US Nuclear Regulatory Commission has developed a list of contaminated sites that warrant special USNRC attention because they pose unique or complex decommissioning issues. This list of radiologically contaminated sites is termed the Site Decommissioning Management Plan (SDMP), and was first issued in 1990. A site is placed on the SDMP list if it has; (1) Problems with the viability of the responsible organization (e.g., the licensee for the site is unable or unwilling to pay for the decommissioning); (2) Large amounts of soil contamination or unused settling ponds or burial grounds that may make the waste difficult to dispose of; (3) The long-term presence of contaminated, unused buildings; (4) A previously terminated license; or (5) Contaminated or potential contamination of the ground water from on-site wastes. In deciding whether to add a site to the SDMP list, the NRC also considers the projected length of time for decommissioning and the willingness of the responsible organization to complete the decommissioning in a timely manner. Since the list was established, 9 sites have been removed from the list, and the current SDMP list contains 47 sites in 11 states. The USNRC annually publishes NUREG-1444, {open_quotes}Site Decommissioning Management Plan{close_quotes}, which updates the status of each site. This paper will discuss the philosophical goals of the SDMP, then will concentrate on the regulatory requirements associated with air cleaning issues at the SDMP sites during characterization and remediation. Both effluent and worker protection issues will be discussed. For effluents, the source terms at sites will be characterized, and measurement techniques will be presented. Off-site dose impacts will be included. For worker protection issues, air sampling analyses will be presented in order to show how the workers are adequately protected and their doses measured to satisfy regulatory criteria during decontamination operations. 1 tab.

  7. The Cleaning of Aluminum Frame Assembly Units

    SciTech Connect

    Shen, T H

    2001-05-16

    The Brulin immersion and the precision cleaning experiments have shown that neither the Brulin solution nor the precision cleaning in AstroPak causes the smut formation on aluminum surfaces. The acid-bath cleaning in GTC is the primary source of the smut formation. The current GTC acid formulation etches the aluminum matrix quite aggressively, but does not appear to appreciably attack the Si particles. Therefore, this acid-bath cleaning will leave the cast-aluminum part surfaces with many protruded Si particles, which could potentially cause smut problems in the cleaning process down-stream. To ensure the removal of all loose Si particles from the cast-aluminum parts, it is necessary to physically hand-wipe and vigorously wash the acid-bath cleaned surfaces. Furthermore, the casting porosity in alloy A356 could be another source in causing high swipe readings in the FAU parts.

    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.

  11. New Air Cleaning Strategies for Reduced Commercial Building Ventilation Energy

    SciTech Connect

    Sidheswaran, Meera; Destaillats, Hugo; Sullivan, Douglas P.; Fisk, William J.

    2010-10-27

    Approximately ten percent of the energy consumed in U.S. commercial buildings is used by HVAC systems to condition outdoor ventilation air. Reducing ventilation rates would be a simple and broadly-applicable energy retrofit option, if practical counter measures were available that maintained acceptable concentrations of indoor-generated air pollutants. The two general categories of countermeasures are: 1) indoor pollutant source control, and 2) air cleaning. Although pollutant source control should be used to the degree possible, source control is complicated by the large number and changing nature of indoor pollutant sources. Particle air cleaning is already routinely applied in commercial buildings. Previous calculations indicate that particle filtration consumes only 10percent to 25percent of the energy that would otherwise be required to achieve an equivalent amount of particle removal with ventilation. If cost-effective air cleaning technologies for volatile organic compounds (VOCs) were also available, outdoor air ventilation rates could be reduced substantially and broadly in the commercial building stock to save energy. The research carried out in this project focuses on developing novel VOC air cleaning technologies needed to enable energy-saving reductions in ventilation rates. The minimum required VOC removal efficiency to counteract a 50percent reduction in ventilation rate for air cleaning systems installed in the HVAC supply airstream is modest (generally 20percent or less).

  12. The utility of anger in promoting clean indoor air policies.

    This investigation examined antecedents associated with support for clean indoor air policies. Participants (N = 550) living in a Midwestern county (population = 62,223) were randomly sampled. Results suggest that beliefs in the health risks associated with secondhand smoke are positively associated with favorable attitudes toward clean indoor air policies, whereas trait reactance is negatively associated with these attitudes. Findings also indicate that risks and trait reactance are indirectly associated with support for clean indoor air policies, mediated through anger arousal toward exposure to secondhand smoke. In addition, regression analyses revealed that health risks, trait reactance, and smoking status explained a significant amount of variance regarding anger toward exposure to secondhand smoke, but only health risks and smoking status accounted for a significant amount of variance toward clean indoor air attitudes. Finally, the Smoking Status x Health Risks interaction was supported for anger toward exposure to secondhand smoke and favorable attitudes toward clean indoor air policies. Our findings suggest the incorporation of anger appeals when promoting clean indoor air policies.

  17. Prototype air cleaning system for a firing range

    1985-01-01

    This report recommends air cleaning system components for the US Army Ballistics Research Laboratory's new large-caliber firing range, which is used for testing depleted uranium (DU) penetrators. The new air cleaning system has lower operating costs during the life of the system compared to that anticipated for the existing air cleaning system. The existing system consists of three banks of filters in series; the first two banks are prefilters and the last are high-efficiency particulate air (HEPA) filters. The principal disadvantage of the existing filters is that they are not cleanable and reusable. Pacific Northwest Laboratory focused the search for alternate air cleaning equipment on devices that do not employ liquids as part of the particle collection mechanism. Collected dry particles were assumed preferable to a liquid waste stream. The dry particle collection devices identified included electrostatic precipitators; inertial separators using turning vanes or cyclones; and several devices employing a filter medium such as baghouses, cartridge houses, cleanable filters, and noncleanable filters similar to those in the existing system. The economics of practical air cleaning systems employing the dry particle collection devices were evaluated in 294 different combinations. 7 references, 21 figures, 78 tables.

  1. Clean Air Slots Amid Dense Atmospheric Pollution in Southern Africa

    NASA Technical Reports Server (NTRS)

    Hobbs, Peter V.

    2003-01-01

    During the flights of the University of Washington's Convair-580 in the Southern African Regional Science Initiative (SAFARI 2000) in southern Africa, a phenomenon was observed that has not been reported previously. This was the occurrence of thin layers of remarkably clean air, sandwiched between heavily polluted air, which persisted for many hours during the day. Photographs are shown of these clean air slots (CAS), and particle concentrations and light scattering coefficients in and around such slot are presented. An explanation is proposed for the propensity of CAS to form in southern Africa during the dry season.

  2. New challenges to air/gas cleaning systems

    SciTech Connect

    Kovach, J.L.

    1997-08-01

    This paper discusses the need for changes in the design and manufacturing of air and gas cleaning systems to meet waste management and site remediation requirements. Current design and manufacturing practices are primarily directed toward evaluating operational problems with existing systems in nuclear reactor facilities. However, nuclear waste management needs have developed which are much broader in scope and have different processing conditions. Numerous examples of air cleaning needs for waste management activities are provided; the major differences from operating facility needs are the requirement for continuous effluent treatment under widely different processing conditions. Related regulatory issues are also discussed briefly. 1 ref.

  3. Measurement of formaldehyde in clean air

    SciTech Connect

    Neitzert, V.; Seiler, W.

    1981-01-01

    A method for the measurement of small amounts of formaldehyde in air has been developed. The method is based on the derivatization of HCHO with 2.4-Denetrophenylhydragine, forming 2.4-Dentrophylhydragine, measured with GC-ECD-technique. HCHO is preconcentrated using a cryogenic sampling technique. The detection limit is 0.05 ppbv for a sampling volume of 200 liter. The method has been applied for measurements in continental and marine air masses showing HCHO mixing ratios of 0.4--5.0 ppbv and 0.2--1.0 ppbv, respectively. HCHO mixing ratios show diurnal variations with maximum values during the early afternoon and minimum values during the early morning. In continental air, HCHO mixing ratios are positively correlated with CO and SO/sub 2/, indicating anthropogenic HCHO sources which are estimated to be 6--11 x 10/sup 12/g/year/sup -1/ on a global scale.

  7. Why business wants the Clean Air Act changed

    SciTech Connect

    Marth, D.

    1982-06-01

    New legislation to modify the Clean Air Act is designed to eliminate the cumbersome requirements that constrain economic growth without lowering present air standards. Environmentalists reject the Luken bill, however, in favor of only fine-tuning the existing Clean Air Act. Ignorance of how the complicated Act works has hampered its implementation by industry. The two sides appear irreconcilable as the debate focuses on the tradeoffs of jobs versus air quality. The Luken bill would ease auto emission requirements enough to lower car prices and reduce unemployment. Environmentalists challenge that claim and seek to tighten specific controls that will reduce the effects of acid rain. President Reagan favors the Luken bill, but political considerations will probably keep the battle concentrated in the House committee. Industry leaders are counting on public pressure to improve both the Act and the economy. (DCK)

  8. Plants Clean Air and Water for Indoor Environments

    Wolverton Environmental Services Inc., founded by longtime government environmental scientist B.C. "Bill" Wolverton, is an environmental consulting firm that gives customers access to the results of his decades of cutting-edge bioremediation research. Findings about how to use plants to improve indoor air quality have been published in dozens of NASA technical papers and in the book, "How to Grow Fresh Air: 50 Houseplants That Purify Your Home or Office." The book has now been translated into 12 languages and has been on the shelves of bookstores for nearly 10 years. A companion book, "Growing Clean Water: Nature's Solution to Water Pollution," explains how plants can clean waste water. Other discoveries include that the more air that is allowed to circulate through the roots of the plants, the more effective they are at cleaning polluted air; and that plants play a psychological role in welfare in that people recover from illness faster in the presence of plants. Wolverton Environmental is also working in partnership with Syracuse University, to engineer systems consisting of modular wicking filters tied into duct work and water supplies, essentially tying plant-based filters into heating, ventilation, and air conditioning (HVAC) systems. Also, the company has recently begun to assess the ability of the EcoPlanter to remove formaldehyde from interior environments. Wolverton Environmental is also in talks with designers of the new Stennis Visitor's Center, who are interested in using its designs for indoor air-quality filters

  6. Cleaning products and air fresheners: exposure to primary and secondary air pollutants

    NASA Astrophysics Data System (ADS)

    Nazaroff, William W.; Weschler, Charles J.

    Building occupants, including cleaning personnel, are exposed to a wide variety of airborne chemicals when cleaning agents and air fresheners are used in buildings. Certain of these chemicals are listed by the state of California as toxic air contaminants (TACs) and a subset of these are regulated by the US federal government as hazardous air pollutants (HAPs). California's Proposition 65 list of species recognized as carcinogens or reproductive toxicants also includes constituents of certain cleaning products and air fresheners. In addition, many cleaning agents and air fresheners contain chemicals that can react with other air contaminants to yield potentially harmful secondary products. For example, terpenes can react rapidly with ozone in indoor air generating many secondary pollutants, including TACs such as formaldehyde. Furthermore, ozone-terpene reactions produce the hydroxyl radical, which reacts rapidly with organics, leading to the formation of other potentially toxic air pollutants. Indoor reactive chemistry involving the nitrate radical and cleaning-product constituents is also of concern, since it produces organic nitrates as well as some of the same oxidation products generated by ozone and hydroxyl radicals. Few studies have directly addressed the indoor concentrations of TACs that might result from primary emissions or secondary pollutant formation following the use of cleaning agents and air fresheners. In this paper, we combine direct empirical evidence with the basic principles of indoor pollutant behavior and with information from relevant studies, to analyze and critically assess air pollutant exposures resulting from the use of cleaning products and air fresheners. Attention is focused on compounds that are listed as HAPs, TACs or Proposition 65 carcinogens/reproductive toxicants and compounds that can readily react to generate secondary pollutants. The toxicity of many of these secondary pollutants has yet to be evaluated. The inhalation

  7. Keeping the Air Clean and Safe: An Anthrax Smoke Detector

    NASA Technical Reports Server (NTRS)

    2005-01-01

    Scientists at work in the Planetary Protection division at NASA s Jet Propulsion Laboratory (JPL) sterilize everything before blasting it to the Red Planet. They take great pains to ensure that all spacecraft are void of bacterial life, especially the microscopic bacteria that can live hundreds of years in their spore states. No one is quite sure what Earthly germs would do on Mars, but scientists agree that it is safest to keep the Martian terrain as undisturbed as possible. Errant Earth germs would also render useless the instruments placed on exploration rovers to look for signs of life, as the life that they registered would be life that came with them from Earth. A team at JPL, headed by Dr. Adrian Ponce, developed a bacterial spore-detection system that uses a simple and robust chemical reaction that visually alerts Planetary Protection crews. It is a simple air filter that traps micron-sized bacterial spores and then submits them to the chemical reaction. When the solution is then viewed under an ultraviolet light, the mixture will glow green if it is contaminated by bacteria. Scientists can then return to the scrubbing and cleaning stages of the sterilization process to remove these harmful bacteria. The detection system is the space-bound equivalent of having your hands checked for cleanliness before being allowed to the table; and although intended to keep terrestrial germs from space, this technology has awesome applications here on Mother Earth. The bacterial spore-detection unit can recognize anthrax and other harmful, spore-forming bacteria and alert people of the impending danger. As evidenced in the anthrax mailings of fall 2001 in the United States, the first sign of anthrax exposure was when people experienced flu-like symptoms, which unfortunately, can take as much as a week to develop after contamination. Anthrax cost 5 people their lives and infected 19 others; and the threat of bioterrorism became a routine concern, with new threats popping up

    Ceramic membranes are among the most promising technologies for membrane applications, owing to their excellent resistance to mechanical, chemical, and thermal stresses. However, membrane fouling is still an issue that hampers the applications at large scales. Air Nano Bubbles (NBs), due to high mass transfer efficiency, could potentially prevent fouling of ceramic membrane filtration processes. In this study, bench and pilot scale ceramic membrane filtration was performed with air NBs to resist fouling. To simulate fouling, humic acid, as an organic foulant, was applied to the membrane flat sheet surface. Complete membrane clogging was achieved in less than 6 h. Membrane defouling (cleaning) was performed by directly feeding of air NBs to the membrane cells. The surface of the ceramic membrane was superbly cleaned by air NBs, as revealed by atomic force microscope (AFM) images before and after the treatment. The permeate flux recovered to its initial level (e.g., 26.7 × 10(-9) m(3)/m(2)/s at applied pressure of 275.8 kPa), which indicated that NBs successfully unclogged the pores of the membrane. The integrated ceramic membrane and air NBs system holds potential as an innovative sustainable technology.

    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 (SO2-4) 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 (SO2-4) trends at median flow were similar to trends determined using a Seasonal Kendall Tau test and Sen slope estimator. The trend of declining SO2-4 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 (NO-3), 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 (???decades).

    Xinliang Chen; Jiangang Qu; Minqi Shi

    1995-02-01

    This paper introduces the design evolution, system schemes and design and construction of main nuclear air cleaning components such as HEPA filter, charcoal adsorber and concrete housing etc. for Qinshan 300MW PWR Nuclear Power Plant (QNPP), the first indigenously designed and constructed nuclear power plant in China. The field test results and in-service test results, since the air cleaning systems were put into operation 18 months ago, are presented and evaluated. These results demonstrate that the design and construction of the air cleaning systems and equipment manufacturing for QNPP are successful and the American codes and standards invoked in design, construction and testing of nuclear air cleaning systems for QNPP are applicable in China. The paper explains that the leakage rate of concrete air cleaning housings can also be assured if sealing measures are taken properly and embedded parts are designed carefully in the penetration areas of the housing and that the uniformity of the airflow distribution upstream the HEPA filters can be achieved generally no matter how inlet and outlet ducts of air cleaning unit are arranged.

  4. Applying the Clean Air Act to municipal solid waste landfills

    SciTech Connect

    Heitz, D.R.; Romzick, P.G.

    1998-12-31

    On March 12, 1996, the EPA promulgated the new Source Performance Standards (NSPS) for Municipal Solid Waste (MSW) Landfills, the first federal air regulation specifically for MSW landfills. Landfills subject to this regulation which exceeded the threshold design capacity also became subject to the Title V operating permit program. This began the application of the Clean Air Act (CAA) to most of these nontraditional air sources. Unlike landfills, typical air sources have easily defined input capacities that correspond to potential emissions while the process creates a product or output. All these concepts are difficult and confusing to apply to MSW landfills. Applicability of the following CAA regulations are specifically addressed in this paper: NSPS for MSW landfills; new Source Review (NSR)/Prevention of Significant Deterioration (PSD); landfill Maximum Achievable Control Technologies (MACT); 112(g) Modification of Major Sources of Hazardous Air Pollutants (HAP); 112(r) Accidental Release Prevention; and Title V. Along with summarizing the potential applicability of each, the main issues are presented along with the current information on the regulations.

  5. The high efficiency steel filters for nuclear air cleaning

    1990-08-01

    We have, in cooperation with industry, developed high-efficiency filters made from sintered stainless-steel fibers for use in several air-cleaning applications in the nuclear industry. These filters were developed to overcome the failure modes in present high-efficiency particulate air (HEPA) filters. HEPA filters are made from glass paper and glue, and they may fail when they get hot or wet and when they are overpressured. In developing our steel filters, we first evaluated the commercially available stainless-steel filter media made from sintered powder and sintered fiber. The sintered-fiber media performed much better than sintered-powder media, and the best media had the smallest fiber diameter. Using the best media, we then built prototype filters for venting compressed gases and evaluated them in our automated filter tester. 12 refs., 20 figs.

  6. EVALUATION OF AIR CLEANING SYSTEMS FOR FFTF CONTAINMENT MARGINS

    SciTech Connect

    POSTMA, A K.; HILLIARD, R K.

    1980-08-01

    Alternative air cleaning concepts were evaluated for possible application to FFTF containment margins. For evaluation purposes, it was assumed that the air cleaning system must process 3.07 m{sup 3}/s (6500 ACFM) of gas containing sodium compound aerosols (mainly NaOH) at temperatures up to 4070C (7000 F) and pressures up to 0.184 MPa (26.4 psia) and accommodate 5450 kg (12,000 lb) of aerosol material. Three systems designed for 90% efficient removal (a venturi scrubber, a submerged gravel scrubber and a spray scrubber) were compared. The submerged gravel scrubber and the venturi scrubber were rated as prime candidates. Four systems designed for 99% removal efficiency (the two optimum scrubbers chosen for 90% removal efficiency fitted with fibrous elements, a sand and gravel filter and a HEPA filter bank) were compared. The tI~ scrubbers were again rated as prime candidates. Both the sand and gravel filter and the HEPA filter bank were found to be excessively large and costly. Considerable experience supports the use of the optimum scrubber systems and it is concluded that their use is technically feasible for the FFTF containment margins application.

    2016-08-01

    In the framework of a nationwide survey on indoor air quality conducted from September 2009 to June 2011 in 310 nurseries, kindergartens, and elementary schools in all regions of France, cleaning practices and products were described through an extensive questionnaire completed on-site by expert building inspectors. The questionnaire included the cleaning frequencies and periods, cleaning techniques, whether windows were open during cleaning, and the commercial names of the products used. Analysis of the questionnaire responses showed that cleaning was generally performed daily for furniture and floors. It was performed mostly in the evening with wet mopping and with one or more windows open. Five hundred eighty-four different cleaning products were listed, among which 218 safety data sheets (SDSs) were available and analyzed. One hundred fifty-two chemical substances were identified in the SDSs. The typical substances in cleaning products included alcohols, chlorides, terpenes, aldehydes, and ethers; more than half of them are irritants. Two endocrine disruptors, 2-phenylphenol and Galaxolide, were identified in two cleaning products used every day to clean the floors, in seven kindergartens and in a nursery respectively. Eleven reactive substances containing C=C double bonds, mostly terpenes, were identified in a wide variety of cleaning products.

    The U.S. Department of Energy awarded Loyola University Chicago and the Institute of Environmental Sustainability (IES) $486,000.00 for the proposal entitled “Chicago clean air, clean water project: Environmental monitoring for a healthy, sustainable urban future.” The project supported the purchase of analytical instruments for the development of an environmental analytical laboratory. The analytical laboratory is designed to support the testing of field water and soil samples for nutrients, industrial pollutants, heavy metals, and agricultural toxins, with special emphasis on testing Chicago regional soils and water affected by coal-based industry. Since the award was made in 2010, the IES has been launched (fall 2013), and the IES acquired a new state-of-the-art research and education facility on Loyola University Chicago’s Lakeshore campus. Two labs were included in the research and education facility. The second floor lab is the Ecology Laboratory where lab experiments and analyses are conducted on soil, plant, and water samples. The third floor lab is the Environmental Toxicology Lab where lab experiments on environmental toxins are conducted, as well as analytical tests conducted on water, soil, and plants. On the south end of the Environmental Toxicology Lab is the analytical instrumentation collection purchased from the present DOE grant, which is overseen by a full time Analytical Chemist (hired January 2016), who maintains the instruments, conducts analyses on samples, and helps to train faculty and undergraduate and graduate student researchers.

  3. Collection and analysis of NASA clean room air samples

    NASA Technical Reports Server (NTRS)

    Sheldon, L. S.; Keever, J.

    1985-01-01

    The environment of the HALOE assembly clean room at NASA Langley Research Center is analyzed to determine the background levels of airborne organic compounds. Sampling is accomplished by pumping the clean room air through absorbing cartridges. For volatile organics, cartridges are thermally desorbed and then analyzed by gas chromatography and mass spectrometry, compounds are identified by searching the EPA/NIH data base using an interactive operator INCOS computer search algorithm. For semivolatile organics, cartridges are solvent entracted and concentrated extracts are analyzed by gas chromatography-electron capture detection, compound identification is made by matching gas chromatogram retention times with known standards. The detection limits for the semivolatile organics are; 0.89 ng cu m for dioctylphlhalate (DOP) and 1.6 ng cu m for polychlorinated biphenyls (PCB). The detection limit for volatile organics ranges from 1 to 50 parts per trillion. Only trace quantities of organics are detected, the DOP levels do not exceed 2.5 ng cu m and the PCB levels do not exceed 454 ng cu m.

    2016-03-01

    This field campaign funded the participation of scientists from seven different research groups and operated over thirty instruments during the Winter Intensive Operating Period (January-February 2012) of the Clean Air for London (ClearfLo) campaign. The campaign took place at a rural site in Detling, UK, 45 kilometers southeast of central London. The primary science questions for the ClearfLo winter IOP (intensive operational periods) were: 1) “what is the urban increment of particulate matter (PM) and other pollutants in the greater London area?” and 2) “what is the contribution of solid fuel use for home heating to wintertime PM?” An additional motivation for the Detling measurements was the question of whether coatings on black carbon particles enhance absorption.

    In the future, we may be able use air cleaning systems and reduce rates of ventilation (i.e., reduce rates of outdoor air supply) to save energy, with indoor air quality (IAQ) remaining constant or even improved. The opportunity is greatest for commercial buildings because they usually have a narrower range of indoor pollutant sources than homes. This article describes the types of air cleaning systems that will be needed in commercial buildings.

  6. Going to jail Utility executives and the New Clean Air Act

    SciTech Connect

    Steinzor, R.I. )

    1992-03-01

    A little-noticed provision of the Clean Air Act Amendments of 1990 requires all affected sources and units to appoint a natural person to serve as their designated representative, or DR, before they get a permit to operate. (Under the law, sources are entire power plants, while units are individual generators or boilers producing steam for electricity). DRs have a demanding job. Not only must they certify the truth of every statement in the permit application, but once the permit is issued, they must also ensure ongoing compliance. If violations occur, DRs even have an obligation to turn the unit or source in to the regulators. Failures to file or false statements in filings can trigger civil and, in the most egregious cases, criminal penalties, including fines and jail terms.

  8. 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.

  10. Effect of laminar air flow and clean-room dress on contamination rates of intravenous admixtures.

    PubMed

    Brier, K L; Latiolais, C J; Schneider, P J; Moore, T D; Buesching, W J; Wentworth, B C

    1981-08-01

    The effect of laminar air flow conditions and clean-room dress on the microbial contamination rates of intravenous admixtures was investigated. Intravenous admixtures were prepared by one investigator using aseptic technique under four environmental conditions: laminar air flow conditions with clean-room dress; laminar air flow without clean-room dress; clean table top with clean-room dress; and clean table top without clean-room dress. In each environmental condition, 350 admixtures were compounded. Negative-control samples (n = 150) were also tested, as were 10 positive-control samples. Samples were tested in each of two growth media and incubated at 35 degrees C for 14 days or until growth occurred. The incidence of contamination of admixtures compounded in laminar air flow conditions was significantly less than the contamination of those compounded on a clean table top (p less than 0.05) regardless of the operator's dress. The incidence of contamination of admixtures compounded while wearing clean-room dress was not significantly different from those prepared while not wearing clean-room dress regardless of the environment in which the admixture was prepared. The overall low level of contamination [0.79% (11/1400)] was inconclusive regarding the effect of dress on the incidence of contamination when admixtures were prepared under LAF conditions. It is concluded that, when one adheres to aseptic technique, the environment in which admixtures are compounded is the most important variable affecting the microbial contamination rate.

  11. Further bacteriological evaluation of the TOUL mobile system delivering ultra-clean air over surgical patients and instruments.

    PubMed

    Thore, M; Burman, L G

    2006-06-01

    Two mobile TOUL-400 units (types 1 and 2) that produce an exponential ultra-clean air flow (EUA) via a mobile screen were evaluated (maximum height from floor to centre of screen: type 1, 1.4m; type 2, 1.6m). Bacterial deposition rates were lowered by >60% (P=0.001) over a table area of 1.7 m (length)x1.0m (width) with the TOUL-400 type 1 unit, and the mean air count at 1.0m from the screen was reduced from 23 to 1.6 colony-forming units (CFU)/m3 in experiments in a room with six air changes/h (ACH). The corresponding reductions were two- to three-fold greater in an operating room (OR) with 16 ACH due to higher bacterial contamination levels in the control experiments. The dramatic but localized reduction of the deposition rate recorded on one 14-cm settle plate (>2376-fold at 0.8m from the screen in the OR) apparently reflected the focus of the EUA. The impact of the TOUL-400 unit was underestimated by almost 100-fold by the air counts of bacteria recorded in parallel at the same sampling point (26.5-fold reduction). During sham coronary angiography and sham hip arthroplasty performed in a room with six ACH, ultra-clean air (<10 CFU/m3) was obtained over the incision area with the TOUL-400 type 2 unit when the EUA was undisturbed (maximum screen-wound distance 1.7 m). In actual coronary angiography (room with six ACH, screen-wound distance 2.0-2.3m) and various surgical procedures in the OR (screen-wound distance 1.4-1.8m), ultra-clean air was obtained at the wound in three of 18 instances, characterized by undisturbed air flow and a maximum distance of 1.8 m. The newly developed TOUL-300 surgical instrument table (1.3-1.7 x 0.6m), equipped at one end with the same EUA unit as the TOUL-400 unit, was evaluated for a room with six ACH and an OR with 16 ACH. It yielded ultra-clean air at 0.8m (1.9 CFU/m3, 96% reduction, P=0.01) and reduced the deposition rate by >60% over most of the table surface.

  12. 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.

    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.

  14. The Clean Air Act impacts on rail coal

    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.

    2011-10-01

    The Clean Air Regulatory Agenda (CARA) Mercury Science Program was developed to provide scientific information to support regulatory activities and accountability pertaining to atmospheric emissions of mercury in Canada. The first phase of the science program, entitled "Setting-the-Baseline", sought to achieve the following: identify key indicators of the state-of-the-Canadian environment with respect to the transport, fate and effects of mercury; define these indicators; and, understand the processes that relate these indicators to anthropogenic emissions of mercury. To achieve these outcomes, a consultative process was used to identify the scientific needs of the agenda for mercury; understand Canada's scientific capacity; and, develop a plan to fulfill these scientific needs. The science plan that emerged from this process was structured around the themes of atmospheric monitoring, landscape-based risk assessment, ecological risk assessment, ecosystem modeling, and trends. Implementation of the science plan necessitated a multi-disciplinary and extensively partnered program. To date, the CARA Mercury Science Program is producing coordinated science at the national-scale that aims to directly assess the effectiveness of the CARA for mercury and for many of Canada's other mercury-related policies.

    2011-10-31

    The research carried out in this project focuses on developing novel volatile organic compounds (VOCs) air cleaning technologies needed to enable energy-saving reductions in ventilation rates. we targeted a VOC air cleaning system that could enable a 50% reduction in ventilation rates. In a typical commercial HVAC system that provides a mixture of recirculated and outdoor air, a VOC air cleaner in the supply airstream must have a 15% to 20% VOC removal efficiency to counteract a 50% reduction in outdoor air supply.

  14. Reticle storage in microenvironments with extreme clean dry air

    Gettel, Astrid; Glüer, Detlev; Honold, Alfred

    2012-11-01

    Haze formation on the patterned metal surface of reticles is a known problem for IC manufacturers that can impact device yield and increase operational costs due to the need for more frequent cleaning of the reticles. Storage of reticles in an ultraclean environment can reduce haze formation and reduce operational costs. We examined the contamination levels of a new type of reticle stocker that stores reticles in microenvironments which are continuously purged with extreme clean dry air (XCDA). Each microenvironment consists of twelve vertically stacked reticle storage slots which can be opened at any slot. The design of the microenvironment includes an XCDA supply that provides a homogeneous horizontal flow of XCDA between the reticles. Figure 1. Reduction of contamination levels inside the storage microenvironment as a function of XCDA flow rate. As shown in Fig. 1, continuous XCDA purge reduces the contaminant levels inside the microenvironment. The amount of reduction depends on the XCDA purge flow rate and the chemical species. Volatile organic substances can be reduced by more than two orders of magnitude. Humidity is reduced less because the plastic material of the storage microenvironment incorporates water in its matrix and can release moisture to the extremely dry atmosphere. Chemical filters applied to mini- or microenvironments typically reduce the contaminant levels only by 95-99% and do not reduce the humidity. To pick and place reticles, the reticle storage microenvironment must be opened. The transient contaminant levels inside the empty microenvironment show an increase at the moment when the microenvironment is opened. Under the given conditions, the microenvironment returns to equilibrium levels with a time constant of 105 seconds (see Fig. 2). Similar dynamic response was measured for IPA and acetone. Figure 2. Transient humidity when the storage microenvironment was opened for reticle handling. The impact of handling on reticles stored inside

  1. An analysis of candidates for addition to the Clean Air Act list of hazardous air pollutants.

    PubMed

    2004-02-01

    There are 188 air toxics listed as hazardous air pollutants (HAPs) in the Clean Air Act (CAA), based on their potential to adversely impact public health. This paper presents several analyses performed to screen potential candidates for addition to the HAPs list. We analyzed 1086 HAPs and potential HAPs, including chemicals regulated by the state of California or with emissions reported to the Toxics Release Inventory (TRI). HAPs and potential HAPs were ranked by their emissions to air, and by toxicity-weighted (tox-wtd) emissions for cancer and noncancer, using emissions information from the TRI and toxicity information from state and federal agencies. Separate consideration was given for persistent, bioaccumulative toxins (PBTs), reproductive or developmental toxins, and chemicals under evaluation for regulation as toxic air contaminants in California. Forty-four pollutants were identified as candidate HAPs based on three ranking analyses and whether they were a PBT or a reproductive or developmental toxin. Of these, nine qualified in two or three different rankings (ammonia [NH3], copper [Cu], Cu compounds, nitric acid [HNO3], N-methyl-2-pyrrolidone, sulfuric acid [H2SO4], vanadium [V] compounds, zinc [Zn], and Zn compounds). This analysis suggests further evaluation of several pollutants for possible addition to the CAA list of HAPs.

  2. Air Pollution Studies in Metromanila and Catalysis Technology Towards Clean Air Philippines

    NASA Astrophysics Data System (ADS)

    Gallardo, S. M.

    - Considerable air quality and emission data gathered in Metropolitan Manila (MM) led to the development of automobile exhaust treatment catalysts as well as their continued improvement. Findings of a 5-year (1993-1998) collaborative work on the development of base metal oxide catalysts for automobile exhaust are summarized here. One study in 1991 reveals an average 16% increase in the number of motor vehicles in MM where 16% are new and the rest are old ones. Another study in 1992 shows the CO and hydrocarbon emission levels from different types of motor vehicles in MM as a function of the age of the vehicle, type of fuel, and the operating condition. Reports of the Department of Environment and Natural Resources (DENR) and other related studies also provided data showing the quality of air in MM. Currently, there are several requirements to further improve the catalyst performance towards the reduction of NOX and to develop catalyst-sorbent for simultaneous NOX-SOX removal. This is so because of the present condition of rain acidification that is found in certain places in MM. These air quality and emission data are needed not only to establish practical emission standards for motor vehicles and the stationary industries and power plants but also in the development of technologies for air pollution control and other clean technologies for cleaner air in the country.

  3. Precision cleaning verification of fluid components by air/water impingement and total carbon analysis

    NASA Technical Reports Server (NTRS)

    Barile, Ronald G.; Fogarty, Chris; Cantrell, Chris; Melton, Gregory S.

    1994-01-01

    NASA personnel at Kennedy Space Center's Material Science Laboratory have developed new environmentally sound precision cleaning and verification techniques for systems and components found at the center. This technology is required to replace existing methods traditionally employing CFC-113. The new patent-pending technique of precision cleaning verification is for large components of cryogenic fluid systems. These are stainless steel, sand cast valve bodies with internal surface areas ranging from 0.2 to 0.9 sq m. Extrapolation of this technique to components of even larger sizes (by orders of magnitude) is planned. Currently, the verification process is completely manual. In the new technique, a high velocity, low volume water stream impacts the part to be verified. This process is referred to as Breathing Air/Water Impingement and forms the basis for the Impingement Verification System (IVS). The system is unique in that a gas stream is used to accelerate the water droplets to high speeds. Water is injected into the gas stream in a small, continuous amount. The air/water mixture is then passed through a converging/diverging nozzle where the gas is accelerated to supersonic velocities. These droplets impart sufficient energy to the precision cleaned surface to place non-volatile residue (NVR) contaminants into suspension in the water. The sample water is collected and its NVR level is determined by total organic carbon (TOC) analysis at 880 C. The TOC, in ppm carbon, is used to establish the NVR level. A correlation between the present gravimetric CFC113 NVR and the IVS NVR is found from experimental sensitivity factors measured for various contaminants. The sensitivity has the units of ppm of carbon per mg/sq ft of contaminant. In this paper, the equipment is described and data are presented showing the development of the sensitivity factors from a test set including four NVRs impinged from witness plates of 0.05 to 0.75 sq m.

  18. Effectiveness of HVAC duct cleaning procedures in improving indoor air quality.

    PubMed

    Ahmad, I; Tansel, B; Mitrani, J D

    2001-12-01

    Indoor air quality has become one of the most serious environmental concerns as an average person spends about 22 hr indoors on a daily basis. The study reported in this article, was conducted to determine the effectiveness of three commercial HVAC (Heating Ventilation Air Conditioning) duct cleaning processes in reducing the level of airborne particulate matter and viable bioaerosols. The three HVAC sanitation processes were: (1) Contact method (use of conventional vacuum cleaning of interior duct surfaces); (2) Air sweep method (use of compressed air to dislodging dirt and debris); (3) Rotary brush method (insertion of a rotary brush into the ductwork to agitate and dislodge the debris). Effectiveness of these sanitation processes was evaluated in terms of airborne particulate and viable bioaerosol concentrations in residential homes. Eight identical homes were selected in the same neighborhood. Two homes were cleaned using each procedure and two were used as controls. It was found that both particle count readings and bioaerosol concentrations were higher when cleaning was being performed than before or after cleaning, which suggests that dirt, debris and other pollutants may become airborne as a result of disturbances caused by the cleaning processes. Particle count readings at 0.3 micron size were found to have increased due to cigarette smoking. Particle counts at 1.0 micron size were reduced due to HVAC duct cleaning. Post-level bioaerosol concentrations, taken two days after cleaning, were found to be lower than the pre-level concentrations suggesting that the cleaning procedures were effective to some extent. Homes cleaned with the Air Sweep procedure showed the highest degree of reduction in bioaerosol concentration among the three procedures investigated.

    This environmental assessment (EA) was prepared by the U.S.Department of Energy (DOE), with compliance with the National Environmental Policy Act (NEPA) of 1969, Council on Environmental Quality (CE) regulations for implementating NEPA (40 CFR 1500-1508) and DOE regulations for compliance with NEPA (10 CFR 1021), to evaluate the potential environmental impacts associated with a proposed demonstration project to be cost-shared by DOE and Custom Coals International (CCI) under the Clean Coal Technology (CCT) Demonstration Program of DOE`s Office of Fossil Energy. CCI is a Pennsylvania general partnership located in Pittsburgh, PA engaged in the commercialization of advanced coal cleaning technologies. The proposed federal action is for DOE to provide, through a cooperative agreement with CCI, cost-shared funding support for the land acquisition, design, construction and demonstration of an advanced coal cleaning technology project, {open_quotes}Self-Scrubbing Coal: An Integrated Approach to Clean Air.{close_quotes} The proposed demonstration project would take place on the site of the presently inactive Laurel Coal Preparation Plant in Shade Township, Somerset County, PA. A newly constructed, advanced design, coal preparation plant would replace the existing facility. The cleaned coal produced from this new facility would be fired in full-scale test burns at coal-fired electric utilities in Indiana, Ohio and PA as part of this project.

    Objectives. We examined the effects of key political institutional factors on the advancement of state-level clean indoor air laws. Methods. We performed an observational study of state-level clean indoor air law enactment among all 50 US states from 1993 to 2010 by using extended Cox hazard models to assess risk of enacting a relevant law. Results. During the 18-year period from 1993 to 2010, 28 states passed a law covering workplaces, 33 states passed a law covering restaurants, 29 states passed a law covering bars, and 16 states passed a law covering gaming facilities. States with term limits had a 2.15 times greater hazard (95% confidence interval [CI] = 1.27, 3.65; P = .005) of enacting clean indoor air laws. The presence of state-level preemption of local clean indoor air laws was associated with a 3.26 times greater hazard (95% CI = 1.11, 9.53; P = .031) of state-level policy enactment. In the presence of preemption, increased legislative professionalism was strongly associated (hazard ratio = 3.28; 95% CI = 1.10, 9.75; P = .033) with clean indoor air law enactment. Conclusions. Political institutional factors do influence state-level clean indoor air law enactment and may be relevant to other public health policy areas. PMID:24825239

    The aim of the study was to valuate effectiveness of the air condition system in hospitals. It was done by estimation of bacteria and fungi concentration in the air. The study were performed in ten hospital rooms which were protected by EU 13 or EU 9 filters. Possible the most important source of fungi was not treated air incoming from outside. Only in four of the rooms concentrations of the fungi in the air were satisfactory and not exceeded 20 cfu/m3 (cfu--colony forming unit). However in two of them the number of fungi rise 4-5 times after the windows were opened. Concentration of the fungi in operating theater number 2 (1-2 cfu/m3) allow to valuate efficiency of air conditioning systems. The lowest bacteria concentration was in Intensive Care Unit (73 cfu/m3) but the highest in instrumentalists rum (1427 cfu/m3. where according to high fungi concentration (116 cfu/m3) the air conditioning systems was switched of and the ventilation was by open windows.

  6. Self-Scrubbing Coal -- an integrated approach to clean air

    SciTech Connect

    Harrison, K.E.

    1997-12-31

    Carefree Coal is coal cleaned in a proprietary dense-media cyclone circuit, using ultrafine magnetite slurries, to remove noncombustible material, including up to 90% of the pyritic sulfur. Deep cleaning alone, however, cannot produce a compliance fuel from coals with high organic sulfur contents. In these cases, Self-Scrubbing Coal will be produced. Self-Scrubbing Coal is produced in the same manner as Carefree Coal except that the finest fraction of product from the cleaning circuit is mixed with limestone-based additives and briquetted. The reduced ash content of the deeply-cleaned coal will permit the addition of relatively large amounts of sorbent without exceeding boiler ash specifications or overloading electrostatic precipitators. This additive reacts with sulfur dioxide (SO{sub 2}) during combustion of the coal to remove most of the remaining sulfur. Overall, sulfur reductions in the range of 80--90% are achieved. After nearly 5 years of research and development of a proprietary coal cleaning technology coupled with pilot-scale validation studies of this technology and pilot-scale combustion testing of Self-Scrubbing Coal, Custom Coals Corporation organized a team of experts to prepare a proposal in response to DOE`s Round IV Program Opportunity Notice for its Clean Coal Technology Program under Public Law 101-121 and Public Law 101-512. The main objective of the demonstration project is the production of a coal fuel that will result in up to 90% reduction in sulfur emissions from coal-fired boilers at a cost competitive advantage over other technologies designed to accomplish the same sulfur emissions and over naturally occurring low sulfur coals.

    upfront costs of some measures can be prohibitive even when they eventually pay for themselves. But this can be overcome by mechanisms such as international financing of capital costs. For other measures, the costs are typically borne by a few while the benefits accrue to everybody. In such cases civil society and governments must get involved. Governments are starting to act. In February, the US, Canada, Sweden, Bangladesh, Ghana and Mexico launched the Climate and Clean Air Coalition to support implementation of measures like these. This coalition will hopefully expand and achieve rapid, widespread adoption of measures to cut black carbon and ozone. While the climate benefits will be substantial, it is important to note that these measures cannot substitute for cuts in carbon dioxide. Black carbon, ozone, carbon monoxide and methane stay in the atmosphere for a fairly short time - a few days for black carbon and about a decade for methane. They thus respond quickly to emissions changes and give us substantial leverage over near-term climate change. In contrast, carbon dioxide is very long-lived and so responds slowly to emissions changes. This means that cuts have little immediate impact, but it also means they must be made now to avoid disastrous changes later on. Controlling short-lived climate pollutants is thus an issue of fairness. Much as failure to reduce carbon dioxide emissions soon would condemn future generations to disastrous change, failure to reduce near-term climate change condemns those alive today to suffer worsening effects of the sort already seen. Some wonder if we really can do both. We can, and we must.

    Air cleaning techniques have been applied worldwide with the goal of improving indoor air quality. The effectiveness of applying these techniques varies widely, and pollutant removal efficiency is usually determined in controlled laboratory environments which may not be realized in practice. Some air cleaners are largely ineffective, and some produce harmful by-products. To summarize what is known regarding the effectiveness of fan-driven air cleaning technologies, a state-of-the-art review of the scientific literature was undertaken by a multidisciplinary panel of experts from Europe, North America, and Asia with expertise in air cleaning, aerosol science, medicine, chemistry and ventilation. The effects on health were not examined. Over 26,000 articles were identified in major literature databases; 400 were selected as being relevant based on their titles and abstracts by the first two authors, who further reduced the number of articles to 160 based on the full texts. These articles were reviewed by the panel using predefined inclusion criteria during their first meeting. Additions were also made by the panel. Of these, 133 articles were finally selected for detailed review. Each article was assessed independently by two members of the panel and then judged by the entire panel during a consensus meeting. During this process 59 articles were deemed conclusive and their results were used for final reporting at their second meeting. The conclusions are that: (1) None of the reviewed technologies was able to effectively remove all indoor pollutants and many were found to generate undesirable by-products during operation. (2) Particle filtration and sorption of gaseous pollutants were among the most effective air cleaning technologies, but there is insufficient information regarding long-term performance and proper maintenance. (3) The existing data make it difficult to extract information such as Clean Air Delivery Rate (CADR), which represents a common benchmark for

    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.

    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

  11. Meeting the future challenges of air quality management in the United States.

    PubMed

    Bradley, Michael J

    2008-01-01

    The U.S. Clean Air Act (CAA, or the Act) and its amendments has achieved substantial progress in cleaning up the nation's air. Over the past 30 years, the CAA reduced emissions of the 6 principal ("criteria") pollutants by over 25%, even while gross domestic product (GDP) has increased over 150% and population and energy consumption rose by nearly 40%. However, despite the tremendous gains the Act has brought, the country's air quality management (AQM) system still faces substantial challenges. In response to a congressional request for an independent evaluation of the overall effectiveness of the CAA, the National Research Council formed the Committee on Air Quality Management. Composed of 25 members with diverse areas of air quality expertise, the committee was charged with developing scientific and technical recommendations for strengthening the nation's AQM system. In 2004, the National Academies published their recommendations in a text entitled Air Quality Management in the United States (National Research Council, 2004).

  12. Evaluation of various activated carbons for air cleaning - Towards design of immune and sustainable buildings

    NASA Astrophysics Data System (ADS)

    There are increased demands for security, sustainability and indoor air quality in today's building design, construction, operation and maintenance. Installation of air cleaning systems can improve the indoor air quality by reducing the air pollution levels, and enhance the building security against sudden release of chemical and/or biological agents. At the same time, air cleaning techniques may reduce the building energy consumption by reducing the outdoor air supply rate, hence lowering the needs for conditioning of outdoor air. While the air filtration of particulate matter is well standardized, the standards against which the performance of air cleaning for gaseous contaminants is measured or classified are still under development. This study examined the performance of various granular activated carbons (GACs) for the removal of volatile organic compounds (VOCs) from mechanically ventilated buildings. Eight different GACs (three virgin and five impregnated) were tested against toluene using a dynamic test system. The virgin GACs showed better performance than impregnated ones, the percentage and the type of impregnation affected the removal efficiencies. Tests were also conducted with selected GACs against toluene, cyclohexane and ethyl acetate at relative humidity (RH) values of 30%, 50% and 70%. The effect of humidity was dependant on the VOC used. Both for toluene and cyclohexane, the removal efficiency decreased as RH increased. However, higher humidity showed a positive impact on the removal of ethyl acetate.

    Sterling Organics produces the analgesic paracetamol (acetaminophen) at its Dudley, England, plant. The wastewater from the batch process contains intermediates such as para-aminophenol (PAP) and byproducts such as thiosulfates, sulfites and sulfides. To stay ahead of increasingly strict environmental legislation, Sterling Organics installed a wet-air oxidation system at the Dudley facility in August 1992. The system is made by Zimpro Environmental Inc. (Rothschild, Wis.). Zimpro's wet-air oxidation system finds a way around the limitations of purely chemical or physical processes. In the process, compressed air at elevated temperature and pressure oxidizes the process intermediates and byproducts and removes the color from the wastewater.

  4. Exemptions for hookah bars in clean indoor air legislation: a public health concern.

    PubMed

    Noonan, Devon

    2010-01-01

    Popularity of waterpipe smoking or hookah smoking in the United States has been growing for some time now among youth and young adults. Currently, many cities and states have exemptions that allow hookah bars to remain in operation despite the passage of clean indoor air legislation. From a public health perspective this is concerning for many reasons. One public health concern with the increase in popularity of this type of tobacco use is the associated health effects. Another concern is that hookah smoke produces a sweet smelling aroma making it less obvious that patrons and employees of hookah bars are inhaling noxious fumes from mainstream smoke, as well as the toxins from the charcoal that is used to heat the tobacco. The purpose of this paper is to discuss smoke-free air legislation in relation to hookah use, the public health implications of exempting hookah bars from current smoke-free legislation, and implications for the public health nurse in protecting the public from the dangers of second-hand smoke, and limiting this new form of tobacco use.

  5. The future of benefit-cost analyses of the Clean Air Act.

    2002-01-01

    This review examines the first two studies conducted pursuant to a Congressional mandate that the U.S. Environmental Protection Agency analyze the effects of the Clean Air Act on the "public health, economy, and the environment of the United States." While these studies indicate that overall, the nation received good value for the resources it invested in improving air quality over the past three decades, we don't know if even higher value could have been obtained by changing or eliminating certain potentially inefficient elements. The review focuses on the critical policy and technical choices made in the analyses, including the selection of the appropriate baseline and the level of disaggregation for the studies. It is proposed that a potential third analysis focus on potential new policies not yet mandated by law or regulation. It is also proposed that the next study fill in key information gaps, expand the benefit categories, and incorporate new research on topics such as mortality and morbidity benefits, cost uncertainties, and others.

    Population growth and the proliferation of roadways in Southern California have facilitated a glut of mobile air pollution sources (cars and trucks), resulting in substantial atmospheric pollution. Despite successful efforts over the past 40 years to reduce pollution, an alarming set of health effects attributable to air pollution have been described in Southern California. The Children’s Health Study indicates that reduced lung function growth, increased school absences, asthma exacerbation, and new-onset asthma are occurring at current levels of air pollution, with sizable economic consequences. We describe these findings and urge a more aggressive effort to reduce air pollution exposures to protect our children’s health. Lessons from this “case study” have national implications.

  13. Sorbent-Based Gas Phase Air Cleaning for VOCs in CommercialBuildings

    SciTech Connect

    Fisk, William J.

    2006-05-01

    This paper provides a review of current knowledge about the suitability of sorbent-based air cleaning for removing volatile organic compounds (VOCs) from the air in commercial buildings as needed to enable reductions in ventilation rates and associated energy savings. The fundamental principles of sorbent air cleaning are introduced, criteria are suggested for sorbent systems that can counteract indoor VOC concentration increases from reduced ventilation, major findings from research on sorbent performance for this application are summarized, novel sorbent technologies are described, and related priority research needs are identified. Major conclusions include: sorbent systems can remove a broad range of VOCs with moderate to high efficiency, sorbent technologies perform effectively when challenged with VOCs at the low concentrations present indoors, and there is a large uncertainty about the lifetime and associated costs of sorbent air cleaning systems when used in commercial buildings for indoor VOC control. Suggested priority research includes: experiments to determine sorbent system VOC removal efficiencies and lifetimes considering the broad range and low concentration of VOCs indoors; evaluations of in-situ regeneration of sorbents; and an updated analysis of the cost of sorbent air cleaning relative to the cost of ventilation.

    This was a two-phase prospective intervention study in the cardiology intensive care unit (CICU) and medical intensive care unit (MICU) and of a public 1800-bed medical centre in Taiwan. In phase I, cleaning efficacy was monitored by ATP bioluminescence after daily morning cleaning, and only 43.9% of 221 tested surfaces passed. The baseline data were used to define an intervention consisting of a new cleaning protocol as well as a new education/training programme. In phase II, following the intervention, 88.1% of 270 surfaces were found to be clean. The combined infection rate in the CICU and MICU showed a statistically significant decrease of 49.7%.

  19. The California fuel cell partnership: an avenue to clean air

    NASA Astrophysics Data System (ADS)

    Lloyd, Alan C.

    The California Fuel Cell Partnership presently consists of eight private companies, two state agencies and a federal government representative that will attempt to demonstrate the feasibility of fuel cell cars and buses. California has attempted to advance the commercialization of zero-emission vehicles for much of the past decade to help the state reduce its high levels of air pollution. A special advisory panel convened by the California Air Resources Board concluded last year that fuel cell technology could meet the key requirements for automobiles. The successful commercialization of fuel cell vehicles would help to reduce the levels of ozone, fine particles and toxic air contaminants that pose health risks to California's population. This technology can also help to reduce carbon dioxide emissions. California regulations now encourage the development of zero and near-zero emission vehicle technologies, including fuel cells. The Fuel Cell Partnership will operate approximately 50 fuel cell cars and buses until the year 2003 in order to produce important information on the vehicles and fueling infrastructure needed to support them.

  20. The road to Clean Cities: Promoting energy security and cleaner air through alternative fuels

    SciTech Connect

    Chun, C.A.

    1997-12-31

    The United States Department of Energy (DOE) Clean Cities Program is a locally-based government/industry partnership program coordinated by DOE to expand the use of alternatives to gasoline and diesel fuel. By combining local decision-making with the voluntary action of partners, the Clean Cities grass roots approach departs from traditional government programs. It creates an effective plan, carried out at the local level, to establish a sustainable alternative fuels market. The broad goals of the Clean Cities Program are to: reduce dependence on foreign oil, improve the environment, and increase economic growth and competitiveness. The key element of success for this program is partnerships -- public/private partnerships that engage the necessary market forces to accomplish the infusion of new alternative fuels and alternative fuel vehicle (AFV) technologies. DOE does not provide direct funding for acquisition of AFVs and products, but rather, provides market development assistance. DOE technical and management resources are targeted at building local coalitions, coordinating technology product suppliers, and improving market and customer information. Clean Cities works directly with local governments and local businesses and shares innovations along the network of Clean Cities coalitions. Since 1993, Clean Cities has made great strides in diversifying transportation fuel consumption. Voluntary Clean Cities partnerships around the United States have heightened public awareness of alternative fuel usage, increased the number of AFVs on the road, and developed alternative fuels infrastructure throughout North America. The Clean Cities Program encourages sustainable development by reducing a community`s dependence on nonrenewable fossil fuels (both domestic and imported), cleaning up the local and global environment, and boosting local economies through the development of alternative fuels industries.

  7. Impact of cleaning regimes on dental water unit contamination.

    PubMed

    Abdallah, Soad A; Khalil, Ahmed I

    2011-12-01

    Microorganisms that have been identified in dental unit waterlines (DUWLs) are of concern because they can cause infections, especially in immunocompromised patients. This study aimed to assess the incidence of microbial contamination in DUWLs before and after intervention to reduce contamination, and to investigate the presence of coliforms, Escherichia coli and Pseudomonas aeruginosa. Water samples were collected aseptically from the waterlines. The high-speed hand-piece and dental chair units were served by one distillation apparatus, which was fed by the potable tap water of four dental clinics. Different interventions were used: chlorination, flushing before clinics and between patients, draining at the end of the day, and freshly distilled water on a daily basis. There was a significant difference between the level of contamination in the high-speed hand-piece (1.5-2.7 log CFU/ml) and dental chair unit water (2.0-3.5 log CFU/ml). Coliforms (0.9%) E. coli (0.9%) and Pseudomonas (1.8%) were detected during 2008. This study indicates the need to monitor water quality regularly and prevent stagnation in DUWLs to reduce the number of viable bacteria to <100 CFU/ml. We recommend flushing the DUWL for 2 min before the first patient and for 10-20 s between patients, flushing the dental unit at the end of the day and draining it overnight to reduce the development of biofilms, and chlorination of the DUWLs.

  8. Possibilities of mercury removal in the dry flue gas cleaning lines of solid waste incineration units.

    Dry methods of the flue gas cleaning (for HCl and SO2 removal) are useful particularly in smaller solid waste incineration units. The amount and forms of mercury emissions depend on waste (fuel) composition, content of mercury and chlorine and on the entire process of the flue gas cleaning. In the case of high HCl/total Hg molar ratio in the flue gas, the majority (usually 70-90%) of mercury is present in the form of HgCl2 and a smaller amount in the form of mercury vapors at higher temperatures. Removal of both main forms of mercury from the flue gas is dependent on chemical reactions and sorption processes at the temperatures below approx. 340 °C. Significant part of HgCl2 and a small part of elemental Hg vapors can be adsorbed on fly ash and solid particle in the air pollution control (APC) processes, which are removed in dust filters. Injection of non-impregnated active carbon (AC) or activated lignite coke particles is able to remove mainly the oxidized Hg(2+) compounds. Vapors of metallic Hg(o) are adsorbed relatively weakly. Much better chemisorption of Hg(o) together with higher sorbent capacity is achieved by AC-based sorbents impregnated with sulfur, alkali poly-sulfides, ferric chloride, etc. Inorganic sorbents with the same or similar chemical impregnation are also applicable for deeper Hg(o) removal (over 85%). SCR catalysts convert part of Hg(o) into oxidized compounds (HgO, HgCl2, etc.) contributing to more efficient Hg removal, but excess of NH3 has a negative effect. Both forms, elemental Hg(o) and HgCl2, can be converted into HgS particles by reacting with droplets/aerosol of poly-sulfides solutions/solids in flue gas. Mercury captured in the form of water insoluble HgS is more advantageous in the disposal of solid waste from APC processes. Four selected options of the dry flue gas cleaning with mercury removal are analyzed, assessed and compared (in terms of efficiency of Hg-emission reduction and costs) with wet methods and retrofits for more

  9. State Clean Indoor Air Laws and smoking among adults with poor mental health.

    2016-05-05

    Persons with mental illness smoke at twice the rate of the general United States (US) population and die an average of 25-years younger, often from preventable diseases. This study seeks to determine whether disparities in smoking have increased over the past decade and whether Clean Indoor Air Laws (CIALs) are associated with changes in smoking among those with poor mental health. We used a fixed-effects model for estimation. CIALs were associated with 15 per cent decreased odds of smoking among adults in the US. Among those with poor mental health, these same laws had no effect. Between 2000 and 2010, the disparity in smoking rates between these two populations has steadily increased from 1.8 to 2.2 times greater. Given the lack of association between tobacco laws and smoking among those with poor mental health, alternative and more targeted tobacco reduction efforts may be necessary.Journal of Public Health Policy advance online publication, 5 May 2016; doi:10.1057/jphp.2016.17.

    1993-07-01

    The sections of the Clean Air Act Amendments (CAAA) of 1990 that refer to accident prevention are to be found in Title III. Two significant requirements of the CAAA in this respect relate to the responsibilities of the Occupational Safety and Health Administration (OSHA), which has promulgated a new Process Safety Management (PSM) standard and the Environmental Protection Agency (EPA), which at the time of writing, is developing Risk Management Program (RMP) regulations. The focus of this paper is on how the requirements of the CAAA may affect the reasons for performing a Quantitative Risk Assessment (QRA) or may affect the results of QRA. In order to limit the discussion, this paper focuses on HF. First, the CAAA requires that the EPA assess the hazards associated with HF; the EPA's current draft report is discussed. Second, a generic assessment of the risks associated with the use of HF is given, with emphasis on alkylation units in refineries. The principal contributors to risk are listed. Finally, an assessment of OSHA's PSM standard 29 CFR 1910.119, the related requirements of state laws such as California's Risk Management and Prevention Program and the potential requirement of EPA's Risk Management Program are given, including an assessment of how these requirements may influence quantitative estimates of risk. 13 refs., 1 fig.

  11. Effects of venue-specific state clean indoor air laws on smoking-related outcomes.

    PubMed

    Bitler, Marianne P; Carpenter, Christopher S; Zavodny, Madeline

    2010-12-01

    A large literature has documented relationships between state clean indoor air laws (SCIALs) and smoking-related outcomes in the United States. These laws vary within states over time and across venues such as schools, government buildings, and bars. Few studies, however, have evaluated whether the effects of SCIALs are plausibly concentrated among workers who should have been directly affected because they worked at locations covered by the venue-specific restrictions. We fill this gap in the literature using data on private sector workers, government employees, school workers, eating and drinking place workers, and bartenders from the 1992-2007 Tobacco Use Supplements to the Current Population Survey. Our quasi-experimental models indicate robust effects of SCIALs restricting smoking in bars: these laws significantly increased the presence of workplace smoking restrictions as reported by bartenders and reduced the fraction of bartenders who smoke. We do not, however, find that SCIALs in private workplaces, government workplaces, schools, or restaurants increased the presence of workplace smoking restrictions among groups of workers working in venues covered by these laws. This suggests that the smoking reductions associated with SCIALs in previous research are unlikely to have been directly caused by effects of workplace smoking restrictions on workers.

  12. Aerosol optical depth in clean marine and continental northeast Atlantic air

    NASA Astrophysics Data System (ADS)

    2009-10-01

    The aerosol optical depth (AOD) and Ångström exponent for the period 2002-2004 is evaluated for clean marine and continentally influenced air masses over the northeast Atlantic region. Measurements were carried out at the Mace Head atmospheric research station on the west coast of Ireland using a precision filter radiometer which measures the aerosol optical depth at four wavelengths centered at 368, 412, 500, and 862 nm. The clean marine AOD at 500 nm is characterized by a mean value of 0.14 ± 0.06, exhibiting relatively small temporal variability. The Ångström exponent was less than 1 for the majority of cases, having an average value of 0.40 ± 0.29 in clean marine conditions. The latter is consistent with the presence of relatively large supermicron particles, such as sea salt dominating the marine aerosol size distribution. The Ångström exponent shows a distinct seasonal cycle in clean marine air, with maximum values being derived in the summer months and minimum values in the winter. In continental air masses, while the range and standard deviation of the AOD is larger than in clean marine conditions, the overall mean AOD (τ500 = 0.19 ± 0.12) is comparable with the clean marine AOD. The continental Ångström exponent is larger, having a mean value of 1.07 ± 0.32. This is attributed to a dominating accumulation mode in the presence of urban-industrial aerosol particles originating mainly from continental Europe. These results demonstrate how the natural marine AOD can rival polluted AOD over the northeast Atlantic region and highlight the importance of the natural marine aerosol contribution over oceans.

    Listeria monocytogenes (Listeria) causes the third highest number of foodborne illness deaths (an estimated 255) in the United States annually, after nontyphoidal Salmonella species and Toxoplasma gondii (1). Deli meats are a major source of listeriosis illnesses, and meats sliced and packaged at retail delis are the major source of listeriosis illnesses attributed to deli meat (4). Mechanical slicers pose cross-contamination risks in delis and are an important source of Listeria cross-contamination. Reducing Listeria contamination of sliced meats in delis will likely reduce Listeria illnesses and outbreaks. Good slicer cleaning practices can reduce this foodborne illness risk. CDC's Environmental Health Specialists Network (EHS-Net) studied how often retail deli slicers were fully cleaned (disassembled, cleaned, and sanitized) at the Food and Drug Administration (FDA) Food Code-specified minimum frequency of every 4 hours and examined deli and staff characteristics related to slicer cleaning frequency. Interviews with staff members in 298 randomly-selected delis in six EHS-Net sites showed that approximately half of delis fully cleaned their slicers less often than FDA's specified minimum frequency. Chain-owned delis and delis with more customers, more slicers, required manager food safety training, food safety-knowledgeable workers, written slicer-cleaning policies, and food safety-certified managers fully cleaned their slicers more frequently than did other types of delis, according to deli managers or workers. States and localities should require deli manager training and certification, as specified in the FDA Food Code. They should also consider encouraging or requiring delis to have written slicer-cleaning policies. Retail food industry leaders can also implement these prevention efforts to reduce risk in their establishments. Because independent and smaller delis had lower frequencies of slicer cleaning, prevention efforts should focus on these types of

    2011-06-01

    This paper assesses whether the Clean Air Act and its Amendments have been equally successful in ensuring the right to healthful air quality in both advantaged and disadvantaged communities in the United States. Using a method to rank air quality established by the American Lung Association in its 2009 State of the Air report along with EPA air quality data, we assess the environmental justice dimensions of air pollution exposure and access to air quality information in the United States. We focus on the race, age, and poverty demographics of communities with differing levels of ozone and particulate matter exposure, as well as communities with and without air quality information. Focusing on PM2.5 and ozone, we find that within areas covered by the monitoring networks, non-Hispanic blacks are consistently overrepresented in communities with the poorest air quality. The results for older and younger age as well as poverty vary by the pollution metric under consideration. Rural areas are typically outside the bounds of air quality monitoring networks leaving large segments of the population without information about their ambient air quality. These results suggest that substantial areas of the United States lack monitoring data, and among areas where monitoring data are available, low income and minority communities tend to experience higher ambient pollution levels.

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

    PubMed

    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.

    Available in abstract form only. Full text of publication follows: The most commonly identified threats to conventional glass fiber HEPA filter performance are moisture and rapid blinding of filters by smoke. Regenerable filter media composed of ceramics or sintered metal can be utilized as pre-filters to protect the more vulnerable glass fiber HEPA filters in the event of upset conditions. Additionally, used in a pre-filtering application, the use of these regenerable filters can potentially extend the lifetime of conventional units. A series of tests have been conducted using CeraMem ceramic membrane filters in an effort to evaluate their performance after repeated loading and air back pulse cleaning. This was done in an effort to access filter performance after repeated loading/cleaning cycles. The filters were loaded using a solid potassium chloride aerosol challenge. The filters were evaluated for pressure drop and filtering efficiency changes from one cleaning cycle to the next. Additionally, the particle size distribution of the aerosol penetrating the filters was measured. (authors)

  19. A Multilevel Test of Constrained Choices Theory: The Case of Tobacco Clean Air Restrictions.

    PubMed

    Vuolo, Mike; Kadowaki, Joy; Kelly, Brian C

    2016-09-01

    According to Bird and Rieker's sociology of constrained choices, decisions and priorities concerning health are shaped by the contexts-including policy, community, and work/family-in which they are formulated. While each level received attention in the original and subsequent research, we contend their constrained choices theory provides a powerful multilevel framework for modeling health outcomes. We apply this framework to tobacco clean air restrictions, combining a comprehensive database of tobacco policies with the National Longitudinal Survey of Youth 1997 from ages 19 to 31. Using multilevel panel models, we find that clean air policies lower the odds of past 30 day smoking and dependence while controlling for other policy-, city-, and individual-level constraints. We also find unique between- and within-person effects, as well as gender effects, for the constraint levied by smoking bans. We argue for the theory's broad applicability beyond commonly cited findings regarding gender and biological influences.

    2010-07-01

    Because of the harmful effects of secondhand smoke, communities are organizing to pass clean indoor air policies. With youth being considered one of the most vulnerable populations to this health hazard, it can be strategic to campaigns and beneficial to the youth's development to involve them in efforts to control this toxin. However, youth participation in health campaigns is limited because of barriers inherent in these initiatives. This article presents lessons learned from a qualitative case study on the youth involvement in a successful local clean indoor air campaign. Through the analysis of semistructured interviews with the adult members of the campaign, group interviews and questionnaire completion by the youth members of the campaign, and additional insight made possible by participant observation, recommendations are provided to engage and sustain youth involvement in local public health initiatives.

    Political differences between the Senate's effort to fine-tune the Clean Air Act and the House effort to cut back regulations will probably delay reauthorization until next year. Politically vulnerable House members are aware of the jobs versus clean air issue in their debate. The more-modest Senate goals will make compromise difficult. The major issues are automobile emissions, non-attainment penalties, acid rain, and prevention of significant deterioration (PSD) requirements. Reforms at the Environmental Protection Agency will be minimal while Congress debates, although EPA will try to expedite the emission-trading and bubble concepts.

    In July 2003, New York State implemented the Clean Indoor Air Act (CIAA) to reduce exposure to environmental tobacco smoke (ETS). In this cross-sectional study, workers (n=168) completed an interview assessing ETS exposure and provided urine for cotinine analysis. Hospitality workers recruited after implementation of the CIAA had significant reductions in ETS exposure and urine cotinine, compared with those recruited before implementation. The New York State CIAA yielded measurable reductions in ETS exposure for hospitality workers.

    The Clean Air Interstate Rule (CAIR) is expected to reduce transport of air pollutants (e.g. fine sulfate particles) in nonattainment areas in the Eastern United States. CAIR highlights the need for an integrated air quality observational and modeling system to understand sulfate as it moves in multiple dimensions, both spatially and temporally. Here, we demonstrate how results from an air quality model can be combined with a 3d monitoring network to provide decision makers with a tool to help quantify the impact of CAIR reductions in SO2 emissions on regional transport contributions to sulfate concentrations at surface monitors in the Baltimore, MD area, and help improve decision making for strategic implementation plans (SIPs). We sample results from the Community Multiscale Air Quality (CMAQ) model using ensemble back trajectories computed with the NASA Langley Research Center trajectory model to provide Lagrangian time series and vertical profile information, that can be compared with NASA satellite (MODIS), EPA surface, and lidar measurements. Results are used to assess the regional transport contribution to surface SO4 measurements in the Baltimore MSA, and to characterize the dominant source regions for low, medium, and high SO4 episodes.

    Unconstrained energy resource development in the Rocky Mountain west is likely to threaten the environment and the health and well-being of the people. Impacts may be associated with visibility degradation, toxic concentrations of gases, and deposition of acidic or toxic substances. Because the possible benefits of energy development in the region are very large, there is great concern that constraints imposed by air quality regulation may preclude the use of important resources or make unduly expensive energy produced from the region. The conflict between energy and clean air in the region is exacerbated by non-energy sources, such as copper smelters and urban areas, that already pose significant environmental threats. The hard policy question is not how to preserve clean air resources or how to develop energy but how to achieve and balance both goals. The effects and regulatory costs and benefits of air pollution control are discussed, and policy directions to protect air quality while pursuing energy development are presented.

    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.

    This study investigated the formation of secondary pollutants resulting from household product use in the presence of ozone. Experiments were conducted in a 50-m 3 chamber simulating a residential room. The chamber was operated at conditions relevant to US residences in polluted areas during warm-weather seasons: an air exchange rate of 1.0 h -1 and an inlet ozone concentration of approximately 120 ppb, when included. Three products were used in separate experiments. An orange oil-based degreaser and a pine oil-based general-purpose cleaner were used for surface cleaning applications. A plug-in scented-oil air freshener (AFR) was operated for several days. Cleaning products were applied realistically with quantities scaled to simulate residential use rates. Concentrations of organic gases and secondary organic aerosol from the terpene-containing consumer products were measured with and without ozone introduction. In the absence of reactive chemicals, the chamber ozone level was approximately 60 ppb. Ozone was substantially consumed following cleaning product use, mainly by homogeneous reaction. For the AFR, ozone consumption was weaker and heterogeneous reaction with sorbed AFR-constituent VOCs was of similar magnitude to homogeneous reaction with continuously emitted constituents. Formaldehyde generation resulted from product use with ozone present, increasing indoor levels by the order of 10 ppb. Cleaning product use in the presence of ozone generated substantial fine particle concentrations (more than 100 μg m -3) in some experiments. Ozone consumption and elevated hydroxyl radical concentrations persisted for 10-12 h following brief cleaning events, indicating that secondary pollutant production can persist for extended periods.

    Premature infants in neonatal intensive care units (NICUs) are highly susceptible to infection due to the immaturity of their immune systems, and nosocomial infections are a significant risk factor for death and poor neurodevelopmental outcome in this population. To investigate the impact of cleaning within a NICU, a high-throughput short-amplicon-sequencing approach was used to profile bacterial and fungal surface communities before and after cleaning. Intensive cleaning of surfaces in contact with neonates decreased the total bacterial load and the percentage of Streptococcus species with similar trends for total fungal load and Staphylococcus species; this may have clinical relevance since staphylococci and streptococci are the most common causes of nosocomial NICU infections. Surfaces generally had low levels of other taxa containing species that commonly cause nosocomial infections (e.g., Enterobacteriaceae) that were not significantly altered with cleaning. Several opportunistic yeasts were detected in the NICU environment, demonstrating that these NICU surfaces represent a potential vector for spreading fungal pathogens. These results underline the importance of routine cleaning as a means of managing the microbial ecosystem of NICUs and of future opportunities to minimize exposures of vulnerable neonates to potential pathogens and to use amplicon-sequencing tools for microbial surveillance and hygienic testing in hospital environments.

    In May 1988, the Pennsylvania Electric Company (Penelec) and New York State Electric and Gas Corporation (NYSEG) were awarded a contract from the Department of Energy's Pittsburgh Energy and Technology Center (DOE-PETC) to evaluate the performance of a two-inch Air-Sparged Hydrocyclone (ASH) for cleaning fine minus-100-mesh coal. A 24-month study was successfully completed, optimizing the performance of the ASH for cleaning raw classified, naturally-occurring minus-100-mesh Upper Freeport coal, and comparing its performance with Advanced Froth Flotation (AFF), a procedure utilizing conventional flotation equipment operated in an advanced manner (low impeller speeds, starvation float, multiple-stage cleaning, etc.) with highly selective reagents to optimize ash and pyritic sulfur rejection. The economics of cleaning fine coal by both processes at commercial scale, for retrofit and greenfield applications were found to be comparable within the accuracy of the study. Technical performance of the two processes were also found to be essentially identical. Thus, the ASH would be the best choice for a retrofit installation into an existing plant because of requiring less space. Both processes were successful in achieving excellent separations when cleaning the Upper Freeport coal. Both the ASH and AFF circuits were able to produce a clean-coal product of yield (65--80 percent weight recovery) and quality (5--6 percent ash) equivalent to that as theoretically determined by float-sink washability analyses. Combining either of the two fine coal flotation processes with a classifying cyclone circuit resulted in pyritic sulfur rejection values of about 85 percent. 47 refs., 109 figs., 75 tabs.

    Experiments were conducted to quantify emissions and concentrations of glycol ethers and terpenoids from cleaning product and air freshener use in a 50-m{sup 3} room ventilated at {approx}0.5 h{sup -1}. Five cleaning products were applied full-strength (FS); three were additionally used in dilute solution. FS application of pine-oil cleaner (POC) yielded 1-h concentrations of 10-1300 {micro}g m{sup -3} for individual terpenoids, including {alpha}-terpinene (90-120), d-limonene (1000-1100), terpinolene (900-1300), and {alpha}-terpineol (260-700). One-hour concentrations of 2-butoxyethanol and/or dlimonene were 300-6000 {micro}g m{sup -3} after FS use of other products. During FS application including rinsing with sponge and wiping with towels, fractional emissions (mass volatilized/dispensed) of 2-butoxyethanol and d-limonene were 50-100% with towels retained, {approx}25-50% when towels were removed after cleaning. Lower fractions (2-11%) resulted from dilute use. Fractional emissions of terpenes from FS use of POC were {approx}35-70% with towels retained, 20-50% with towels removed. During floor cleaning with dilute solution of POC, 7-12% of dispensed terpenes were emitted. Terpene alcohols were emitted at lower fractions: 7-30% (FS, towels retained), 2-9% (FS, towels removed), and 2-5% (dilute). During air-freshener use, d-limonene, dihydromyrcenol, linalool, linalyl acetate, and {beta}-citronellol were emitted at 35-180 mg d{sup -1} over three days while air concentrations averaged 30-160 {micro}g m{sup -3}.

    With this poster we present the environmental benefit on air quality derived by the application of the CLEAN-ROADS pilot project. The CLEAN-ROADS project addresses the problem of the environmental pollution caused by de-icing salts during winter road maintenance activities in the Province of Trento (Italy). A demonstrative Maintenance Decision Support System (MDSS) has been developed in order to improve the intervention procedures of the road management service. Specifically it aims to optimize the efficiency of how available resources (e.g., salt consumption) are currently used while guaranteeing the current level of road safety. The CLEAN-ROADS project has been tested and validated on a test area located in a valley bottom (Adige Valley), where the highest optimization margins are to be expected. The project supports current road maintenance practices, which has proved to be reliable and accurate, with a new scalable and energy-efficient road monitoring system. This system is based on a network of road weather stations (road weather information system, RWIS) installed on the test route. It is capable to collect real-time data about the road conditions and to perform short-term and now-cast road weather forecasts, which actively integrate weather data and bulletins covering the target area [1]. This poster presents the results obtained from a three-year monitoring activity with the aim to (1) determine the impact of de-icing salts on air quality and (2) quantify the improvements obtained by the application of the CLEAN-ROADS project on air quality. The Ambient Air Quality and Cleaner Air for Europe Directive (2008/50/EC) states that contributions to exceedances of particulate matter PM10 limit values that are attributable to road winter salting may be subtracted when assessing compliance with air quality limit values, once provided that reasonable measures have been taken to lower concentrations [2].

    With the aim of identifying the fungus microbiota in air conditioners in intensive care units (ICUs) within public and private hospitals in Teresina, Piauí, solid material was collected from ten different ICUs. Thirty-three species of Moniliaceae and Dematiaceae were isolated, which was the first report of these in Piauí. High frequencies of Aspergillus niger Van Tieghem (60%), Aspergillus fumigatus Fres (50%), Trichoderma koningii Oudem (50%) and Aspergillus flavus Link: Fr. (40%) were recorded. The air conditioner cleanliness validity had expired in all the ICUs, and the quantity of colony-forming units exceeded the levels permitted by Law 176/00 from the Ministry of Health. It is important to provide individual protection equipment for professionals, adopt hospital infection control measures, raise the awareness of the presence of fungus infection, improve air circulation around the environment, periodically clean the air conditioners, and make health professionals alert to the importance of these fungi in the hospital environment.

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

    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.

    An investigation was conducted on selected locations in air handling units (AHUs) to (a) identify common mold species found on these locations, (b) determine whether some locations (and subsets) featured mold growth sites more frequently than others, (c) ascertain whether the operating condition of AHUs is related to mold contamination, and (d) provide a basis for a microbial sampling protocol for AHUs. A total of 566 tape lifts and 570 swab samples were collected from the blower wheel fan blades, insulation, cooling coil fins, and ductwork from 25 AHUs. All AHU conditions were numerically rated using a heating, ventilation and air-conditioning (HVAC) survey. Results showed that Cladosporium sp. fungi were commonly recovered in terms of growth sites and deposited spores, and they were found mainly in the blower wheel fan blades, the ductwork, and the cooling coil fins. Subsections of the fan blades, insulation, and cooling coil fins showed no preferred area for mold growth sites. Other organisms such as Penicillium sp., Aspergillus sp., and Paecilomyces sp. were recovered from the cooling coil fins and insulation. Because of the widespread prevalence of Cladosporium sp., there was no relationship between mold growth and operating condition. However, the presence of different species of molds in locations other than the blower wheel blades may indicate that the AHU condition is not optimal. A suggested microbial sampling protocol including interpretations of sample results is presented.

    This notice of construction (NOC) requests a categorical approval for construction and operation of certain portable high-efficiency particulate air (HEPA) filtered vacuum radionuclide airborne emission units (HVUs). Approval of this NOC application is intended to allow operation of the HVUs without prior project-specific approval. This NOC does not request replacement or supersedence of any previous agreements/approvals by the Washington State Department of Health for the use of vacuums on the Hanford Site. These previous agreement/approvals include the approved NOCs for the use of EuroClean HEPA vacuums at the T Plant Complex (routine technical meeting 12/10/96) and the Kelly Decontamination System at the Plutonium-Uranium Extraction (PUREX) Plant (routine technical meeting 06/25/96). Also, this NOC does not replace or supersede the agreement reached regarding the use of HEPA hand-held/shop-vacuum cleaners for routine cleanup activities conducted by the Environmental Restoration Project. Routine cleanup activities are conducted during the surveillance and maintenance of inactive waste sites (Radioactive Area Remedial Action Project) and inactive facilities. HEPA hand-held/shop-vacuum cleaners are used to clean up spot surface contamination areas found during outdoor radiological field surveys, and to clean up localized radiologically contaminated material (e.g., dust, dirt, bird droppings, animal feces, liquids, insects, spider webs, etc.). This agreement, documented in the October 12, 1994 Routine Meeting Minutes, is based on routine cleanup consisting of spot cleanup of low-level contamination provided that, in each case, the source term potential would be below 0.1 millirem per year.

For example, the criminal enforcement provisions of {section}113 are expanded both in the range of punishment and in the kinds of activities which are subject to criminal enforcement. Moreover, the Act now contains a number of additional enforcement provisions in addition to those found in {section}113. The purpose of this paper is to discuss both the {section}113 provision and as well, identify those enforcement provisions found outside {section}113. The latter provisions will be taken up first and addressed by Titles of the Act. The discussion of specific sections and subsections of the CAA are necessarily brief and in the nature of highlighting of particular features; like the rest of the CAA, careful reading and analysis is a requirement for full understanding.

  14. A public health context for residual risk assessment and risk management under the clean air act.

    1998-09-01

    The 1990 amendments to the Clean Air Act required the EPA to institute new pollution control technology requirements for industrial sources of air pollution. In part because agreement could not be reached on the best way for the EPA to determine whether any significant risks to human health will remain after the technology controls are in place, the amendments also created a Commission on Risk Assessment and Risk Management and gave the commission a broad mandate to review and make recommendations concerning risk assessment and risk management in federal regulatory programs. In its March 1997 final report to Congress and the administration, the commission recommended a tiered approach to assessing such residual risks. That approach included the idea that when decisions about managing residual risks are made, emissions should be evaluated in the context of other sources of air pollution. Evaluating risks in their larger contexts is consistent with what the commission called a public health approach to environmental risk management. This paper describes the public health approach and how it applies to evaluating residual risks under the Clean Air Act.

    HD-2 grease is deliberately applied to Shuttle Redesigned Solid Rocket Motor (RSRM) D6AC steel hardware parts as a temporary protective coating for storage and shipping. This HD-2 grease is the most common form of surface contamination on RSRM hardware and must be removed prior to subsequent surface treatment. Failure to achieve an acceptable level of cleanliness (HD-2 calcium grease removal) is a common cause of defect incidence. Common failures from ineffective cleaning include poor adhesion of surface coatings, reduced bond performance of structural adhesives, and failure to pass cleanliness inspection standards. The RSRM hardware is currently cleaned and refurbished using methyl chloroform (1,1,1-trichloroethane). This chlorinated solvent is mandated for elimination due to its ozone depleting characteristics. This report describes an experimental study of an aqueous cleaning system (which uses Brulin 815 GD) as a replacement for methyl chloroform. Evaluation of process control parameters for this cleaner are discussed as well as cleaning mechanisms for a spray-in-air process.

    Vehicle cabs equipped with an effective air cleaning and pressurization system, fitted to agricultural and off-road machineries, isolate drivers from the polluted environment, in which they are likely to work. These cabs provide protection against particulate and gaseous pollutants generated by these types of work activities. Two laboratory methods have been applied to determining the performance characteristics of two cabs of different design, namely, optical counting-based measurement of a potassium chloride (KCl) aerosol and fluorescein aerosol-based tracing. Results of cab confinement efficiency measurements agreed closely for these two methods implemented in the study. Measurements showed that high confinement efficiencies can be achieved with cabs, which are properly designed in ventilation/cleaning/airtightness terms. We also noted the importance of filter mounting airtightness, in which the smallest defect is reflected by significant degradation in cab performance. Determination of clean airflow rate by monitoring the decrease in test aerosol concentration in the test chamber gave excellent results. This method could represent an attractive alternative to methods involving gas tracing or air velocity measurement at blowing inlets.

  2. 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.

    The US–China Clean Energy Research Center (CERC) was launched in 2009 by US Energy Secretary Steven Chu, Chinese Minister of Science and Technology Wan Gang, and Chinese National Energy Agency Administrator Zhang Guobao. This 5-year collaboration emerged from the fact that the United States and China are the world’s largest energy producers, energy consumers, and greenhouse gas emitters, and that their joint effort could have significant positive repercussions worldwide. CERC’s main goal is to develop and deploy clean energy technologies that will help both countries meet energy and climate challenges. Three consortia were established to address the most pressing energy-related research areas: Advanced Coal Technology, Clean Vehicles, and Building Energy Efficiency (BEE). The project discussed in this report was part of the CERC-BEE consortia; its objective was to lower energy use in buildings by developing and evaluating technologies that improve the cost-effectiveness of air barrier systems for building envelopes.

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

    Chestnut, L.G.; Watkins, A.M.

    1997-12-31

    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.

    Air quality is a vital element of our environment. Accurate and localized air quality information is critical for characterizing environmental impacts at the local and regional levels. Advances in location-aware handheld devices and air quality modeling have enabled a group of UAHuntsville scientists to develop a mobile app, LocalAQI, that informs users of current conditions and forecasts of up to twenty-four hours, of air quality indices. The air quality index is based on Community Multiscale Air Quality Modeling System (CMAQ). UAHuntsville scientists have used satellite remote sensing products as inputs to CMAQ, resulting in forecast guidance for particulate matter air quality. The CMAQ output is processed to compute a standardized air quality index. Currently, the air quality index is available for the eastern half of the United States. LocalAQI consists of two main views: air quality index view and map view. The air quality index view displays current air quality for the zip code of a location of interest. Air quality index value is translated into a color-coded advisory system. In addition, users are able to cycle through available hourly forecasts for a location. This location-aware app defaults to the current air quality of user's location. The map view displays color-coded air quality information for the eastern US with an ability to animate through the available forecasts. The app is developed using a cross-platform native application development tool, appcelerator; hence LocalAQI is available for iOS and Android-based phones and pads.

    The objective of this study is to estimate the prevalence of self-reported secondhand smoke (SHS) exposures and its association with respiratory symptoms in a sample of young adults residing in a state with a partial clean indoor air law. A cross-sectional telephone survey of Florida households and a single state University was conducted in 2005. Enrolled participants between 18 and 24 years of age completed a 15-20 min interview assessing past and current SHS exposure and current respiratory symptoms (n = 1858). Approximately 60% of the sample were female; nearly 70% were non-Hispanic white, 10% were non-Hispanic Black, and 11% were Hispanic. Over two-thirds reported completing at least some college; 23% reported smoking in the past month. Nearly two-thirds (64%) reported visiting a bar or nightclub which exposed them to SHS in the previous month; nearly half (46%) reported SHS exposure while riding in automobiles; 15% reported occupational SHS exposure; and nearly 9% reported living with at least one smoker. In multivariable models, personal smoking behavior, parental smoking history, and exposure to SHS in automobiles and in bars or nightclubs were significantly associated with increased reports of respiratory symptoms. Despite residing in a "clean" indoor air state, the majority of surveyed young adults continue to report exposure to SHS, especially in automobiles and in bars, and these exposures adversely impact respiratory health. All municipalities should pursue clean indoor air legislation which does not exempt bars and restaurants. Educational campaigns directed at reducing SHS exposure in motor vehicles also are needed.

    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.

    Municipal governments in the United States are well positioned to influence clean energy (energy efficiency and alternative energy) and transportation technology and strategy implementation within their jurisdictions through planning, programs, and codification. Municipal governments are leveraging planning processes and programs to shape their energy futures. There is limited understanding in the literature related to codification, the primary way that municipal governments enact enforceable policies. The authors fill the gap in the literature by documenting the status of municipal codification of clean energy and transportation across the United States. More directly, we leverage online databases of municipal codes to develop national and state-specific representative samples of municipal governments by population size. Our analysis finds that municipal governments with the authority to set residential building energy codes within their jurisdictions frequently do so. In some cases, communities set codes higher than their respective state governments. Examination of codes across the nation indicates that municipal governments are employing their code as a policy mechanism to address clean energy and transportation.

  17. Indoor air quality in hospitality venues before and after implementation of a clean indoor air law--Western New York, 2003.

    PubMed

    2004-11-12

    Secondhand smoke (SHS) contains more than 50 carcinogens. SHS exposure is responsible for an estimated 3,000 lung cancer deaths and more than 35,000 coronary heart disease deaths among never smokers in the United States each year, and for lower respiratory infections, asthma, sudden infant death syndrome, and chronic ear infections among children. Even short-term exposures to SHS, such as those that might be experienced by a patron in a restaurant or bar that allows smoking, can increase the risk of experiencing an acute cardiovascular event. Although population-based data indicate declining SHS exposure in the United States over time, SHS exposure remains a common but preventable public health hazard. Policies requiring smoke-free environments are the most effective method of reducing SHS exposure. Effective July 24, 2003, New York implemented a comprehensive state law requiring almost all indoor workplaces and public places (e.g., restaurants, bars, and other hospitality venues) to be smoke-free. This report describes an assessment of changes in indoor air quality that occurred in 20 hospitality venues in western New York where smoking or indirect SHS exposure from an adjoining room was observed at baseline. The findings indicate that, on average, levels of respirable suspended particles (RSPs), an accepted marker for SHS levels, decreased 84% in these venues after the law took effect. Comprehensive clean indoor air policies can rapidly and effectively reduce SHS exposure in hospitality venues.
