This book was released on 1993 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to reduce the pollutant load to the atmosphere and subsequent damaging effects, Titles I and IV of the Clean Air Act Amendments of 1990 (CAAAs) require reductions in emissions of sulfur dioxide (SO[sub 2]), nitrogen oxides (NO[sub x]), and volatile organic compounds (VOCs). Title IV is aimed at reducing acidic deposition and requires utilities to reduce SO[sub 2] and NO[sub x] emissions to specified levels. As a consequence of this, many utilities will have to install SO[sub 2] and NO[sub x] control technologies. Title I is concerned with bringing regions into compliance with the National Ambient Air Quality Standards (NAAQS) for the criteria pollutants, among which is ozone (O[sub 3]). The NAAQS for O[sub 3] is 120 ppb (parts per billion by volume) hourly average concentration, not to be exceeded four times in three years. O[sub 3] is a secondary pollutant formed in the atmosphere when NO[sub x] and VOCs react together in the presence of sunlight. Utilities are a significant source of NO[sub x] and an unimportant source of VOCs. In the past, O[sub 3] control strategy has focused on reducing VOC emissions because of the possibility that reducing NO[sub x] actually might make O[sub 3] concentrations higher. However, this approach has not worked, perhaps because of underestimation of natural and manmade VOC emissions and transport of O[sub 3] from other regions. Computer modeling has shown that for many highly polluted areas massive NO[sub x] reductions may be necessary in addition to or in place of VOC controls. Utilities are a potential source of these NO[sub x] reductions.

This book was released on 1999-09-23 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Committee on Ozone-Forming Potential for Reformulated Gasoline was asked whether the existing body of scientific and technical information is sufficient to permit a robust evaluation and comparison of the emissions from motor vehicles using different reformulated gasolines based on their ozone-forming potentials and to assess the concomitant impact of that approach on air-quality benefits of the use of oxygenates within the RFG program. As part of its charge, the committee was asked to consider (1) the technical soundness of various approaches for evaluating and comparing the relative ozone-forming potentials of RFG blends, (2) technical aspects of various air-quality issues related to RFG assessment, and (3) the sensitivity of evaluations of the relative ozone-forming potentials to factors related to fuel properties and the variability of vehicle technologies and driving patterns.

Download or read book Tackling Climate Change Through Livestock written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2013 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

Book excerpt: The authorities and responsibilities of the Environmental Protection Agency (EPA) derive primarily from a dozen major environmental statutes. This book provides a concise summary of one of those statutes, the Clean Air Act. It provides a brief history of federal involvement in air quality regulation and of the provisions added by legislation in 1970, 1977 and 1990. It also explains major authorities contained in the Act as well as key terms and references for more detailed information on the Act and its implementation.
Download or read book Rethinking the Ozone Problem in Urban and Regional Air Pollution written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution in the lower atmosphere, or troposphere, threatens the health of humans, animals, and vegetation. This book discusses how scientific information can be used to develop more effective regulations to control ozone. Rethinking the Ozone Problem in Urban and Regional Air Pollution discusses: The latest data and analysis on how tropospheric ozone is formed. How well our measurement techniques are functioning. Deficiencies in efforts to date to control the problem. Approaches to reducing ozone precursor emissions that hold the most promise. What additional research is needed. With a wealth of technical information, the book discusses atmospheric chemistry, the role of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in ozone formation, monitoring and modeling the formation and transport processes, and the potential contribution of alternative fuels to solving the tropospheric ozone problem. The committee discusses criteria for designing more effective ozone control efforts. Because of its direct bearing on decisions to be made under the Clean Air Act, this book should be of great interest to environmental advocates, industry, and the regulatory community as well as scientists, faculty, and students.
