To comply with legal and other standards, businesses and regulators are increasingly required to make decisions based on risk assessments of the potential effects of their activities on the environment. Atmospheric dispersion modelling is a cost-effective method, allowing various scenarios to be explored before expensive investment takes place. This guide offers advice on this environmental management tool. Unlike much of the previous literature, it doesn't focus excessively on the mathematical theory behind the modelling or on modelling for specific regulatory purposes. Instead, it offers an understanding of the background to the methodologies, providing exercises to develop the skills to carry these out and including examples of the use of commercially available models to enable the reader to assess the results of modelling for risk assessment.

A single reference to all aspects of contemporary air dispersion modeling The practice of air dispersion modeling has changed dramatically in recent years, in large part due to new EPA regulations. Current with the EPA's 40 CFR Part 51, this book serves as a complete reference to both the science and contemporary practice of air dispersion modeling. Throughout the book, author Alex De Visscher guides readers through complex calculations, equation by equation, helping them understand precisely how air dispersion models work, including such popular models as the EPA's AERMOD and CALPUFF. Air Dispersion Modeling begins with a primer that enables readers to quickly grasp basic principles by developing their own air dispersion model. Next, the book offers everything readers need to work with air dispersion models and accurately interpret their results, including: Full chapter dedicated to the meteorological basis of air dispersion Examples throughout the book illustrating how theory translates into practice Extensive discussions of Gaussian, Lagrangian, and Eulerian air dispersion modeling Detailed descriptions of the AERMOD and CALPUFF model formulations This book also includes access to a website with Microsoft Excel and MATLAB files that contain examples of air dispersion model calculations. Readers can work with these examples to perform their own calculations. With its comprehensive and up-to-date coverage, Air Dispersion Modeling is recommended for environmental engineers and meteorologists who need to perform and evaluate environmental impact assessments. The book's many examples and step-by-step instructions also make it ideal as a textbook for students in the fields of environmental engineering, meteorology, chemical engineering, and environmental sciences.

This easy-to-read guide links the regulatory and technical aspectsof air quality compliance in one self-contained volume. This unique handbook explains air quality compliance in plainlanguage, free of legalese. Russell E. Erbes draws on twenty yearsof industrial air quality compliance experience as he clarifies thecomplex regulatory and technical issues facing industry in the wakeof the 1990 Clean Air Act Amendments. He guides the reader througha labyrinth of demanding regulations, rising costs, and complexprocedures. A Practical Guide to Air Quality Compliance, Second Edition, sortsthrough requirements and helps environmental professionals managecompliance effectively and efficiently--whatever the needs of theirfacilities. Filled with real-world examples that illustrate bothproblems and solutions, it features: * Unwritten applicability guidelines known only by technicalexperts in air compliance. * Tips on obtaining permits and variances, and monitoring andensuring compliance. * Appendices that explain terms, list air toxins and potentialhealth risks, and more. * Coverage of Title V programs, acid rain provisions, stratosphericozone protection, atmospheric dispersion modeling, and riskassessment methodologies. * A chapter on the new criminal and civil penalties fornoncompliance. * A survey of the major differences among federal, state, and localrequirements. For environmental managers and engineers at industrial facilities,environmental consultants and attorneys, and professionals inregulatory agencies, this practical guide removes the guessworkfrom the air quality compliance process.

This is the new, fourth edition of the book on dispersion modeling of continuous, buoyant air pollution plumes which takes nothing for granted. Every equation is completely derived step-by-step without any complicated or advanced mathematics. Every constraint and assumption is fully explained. A set of self-study exercises is also included with the book.The subjects covered in the book include atmospheric turbulence and stability classes, buoyant plume rise, Gaussian dispersion calculations and modeling, time-averaged concentrations, wind velocity profiles, fumigations, trapped plumes, flare stack plumes and much more ... with a great many example calculations. Copies of the book have been purchased in the U.S.A., Canada, Mexico, South America, Europe, Australia, Africa and Asia (in a total of 57 countries), and are available in over 130 libraries worldwide. The book has been very widely referenced and cited in the technical literature and on the Internet.
