Emission factors (EFs) and results from dispersion models are key components in the air pollution regulatory process. The EPA preferred regulatory model changed from ISCST3 to AERMOD in November, 2007. Emission factors are used in conjunction with dispersion models to predict 24-hour concentrations that are compared to National Ambient Air Quality Standards (NAAQS) for determining the required control systems in permitting sources. This change in regulatory models has had an impact on the regulatory process and the industries regulated. In this study, EFs were developed for regulated particulate matter PM10 and PM2.5 from cotton harvesting. Measured concentrations of TSP and PM10 along with meteorological data were used in conjunction with the dispersion models ISCST3 and AERMOD, to determine the emission fluxes from cotton harvesting. The goal of this research was to document differences in emission factors as a consequence of the models used. The PM10 EFs developed for two-row and six-row pickers were 154 + 43 kg/km2 and 425 + 178 kg/km2, respectively. From the comparison between AERMOD and ISCST3, it was observed that AERMOD EFs were 1.8 times higher than ISCST3 EFs for Emission factors (EFs) and results from dispersion models are key components in the air pollution regulatory process.

From the comparison between AERMOD and ISCST3, it was observed that AERMOD EFs were 1.8 times higher than ISCST3 EFs for absence of solar radiation. Using AERMOD predictions of pollutant concentrations off property for regulatory purposes will likely affect a source's ability to comply with limits set forth by State Air Pollution Regulatory Agencies (SAPRAs) and could lead to inappropriate regulation of the source.

The AERMOD model is evaluated using data from an emission inventory of Lucas County, Ohio for the year 1990, which included actual air pollutant emissions of sulfur dioxide, oxides of nitrogen and particulates. AERMOD is further used to predict 3-hr, monthly, quarterly and annual averages of sulfur dioxide concentrations. For the 3-hr averaging period evaluation for SO2, data has been classified into stable and convective groups based on Monin-Obukhov length, a stability parameter. Uncertainties associated with the model predictions are estimated using the bootstrap resampling method. Confidence intervals on the fractional mean bias, normalized mean square error, geometric mean bias and geometric variance are calculated for each model and difference between models. NMSE versus FB plots are drawn to find whether the model overpredicts or underpredicts. AERMOD did not yield good performance in its prediction of 3-hr and 24-hr average concentrations of the datasets used. The model tended to underpredict in both the stable and convective cases. However, there are equal numbers of overpredictions in the convective case.

In 1969 the North Atlantic Treaty Organization established the Committee on the Challenges of Modern Society. Air Pollution was from the start one of the pri9rity problems under study within the framework of the pilot studies undertaken by this Committee. The organization of a yearly symposium dealing with air pollution modeling and its application is one of the main activities within the pilot study in relation to air pollution. After being organized for five years by the United States and for five years by the Federal Republic of Germany, Belgium, represented by the Prime Minister's Office for Science Policy Programming, became responsible in 1980 for the organization of this symposium. This volume contains the papers presented at the 13th Inter national Technical Meeting on Air Pollution Modeling and its Appli cation held at lIe des Embiez, France, from 14th to 17th September 1982. This meeting was jointly organized by the Prime Minister's Office for Science Policy Programming, Belgium, and the Ministere de l'Environnement, France. The conference was attended by 120 participants and 45 papers have been presented. The closing ses sion of the 13th I. T. M. has been attended by Mr. Alain Bombard, French Minister of the Environment. The members of the selection committee of the 13th I. T. M. were A. Berger (Chairman, Belgium), W. K1ug (Federal Republic of Germany), K. Demerjian (United States of America), L. Santomauro (Italy), M. L. Williams (United Kingdom), H. Van Dop (The Netherlands), H. E. Turner (Canada), C.

Finishing this book is giving me a mixture of relief, satisfaction and frus tration. Relief, for the completion of a project that has taken too many of my evenings and weekends and that, in the last several months, has become almost an obsession. Satisfaction, for the optimistic feeling that this book, in spite of its many shortcomings and imbalances, will be of some help to the air pollution scientific community. Frustration, for the impossibility of incorporating newly available material that would require another major review of several key chap ters - an effort that is currently beyond my energies but not beyond my desires. The first canovaccio of this book came out in 1980 when I was invited by Computational Mechanics in the United Kingdom to give my first Air Pollution Modeling course. The course material, in the form of transparencies, expanded, year after year, thus providing a growing working basis. In 1985, the ECC Joint Research Center in Ispra, Italy, asked me to prepare a critical survey of mathe matical models of atmospheric pollution, transport and deposition. This support gave me the opportunity to prepare a sort of "first draft" of the book, which I expanded in the following years.
