Office of Air Quality Air Dispersion Modeling The Indiana Department of Environmental Management's Office of Air Quality (IDEM OAQ) requires air dispersion modeling to be conducted to demonstrate that a source will not cause or significantly contribute to the violation of air quality standards. Modeling also must comply with the Prevention of Significant Deterioration (PSD) increments, or toxic thresholds. IDEM follows all air quality modeling procedures set forth in the U.S. Environmental Protection Agency (EPA) Guideline on Air Quality Models for PSD, nonattainment New Source Review (NSR), and State Implimentation Plan (SIP) revisions. IDEM Air Quality Modeling Policies - This document is currently under revision and is not available from our web site. As soon as the revisions have been completed, we will post the new policies. If you should have any questions concerning modeling, please contact Ken Ritter at 317-233-5682.

Air Quality Bureau Dispersion Modeling Section What is Dispersion Modeling? Air dispersion modeling is a way to show the transport of air pollutants. This is performed mathematically using a computer program. By using information such as meteorology and source emissions, models can calculate pollutant concentrations in the air such as: Why is Air Dispersion Modeling Used? Air dispersion modeling is used for two major reasons. 1. Modeling can predict pollutant concentration estimates at most locations where there are no air monitors. 2. Models can predict the potential impact of new sources before they are built as well as how new pollution control devices will affect the outcome of the pollutant. Air Dispersion Modeling Activities in New Mexico The modeling activities in New Mexico are used in: Modeling new and modified sources for air quality permits - Determining if existing sources are complying with air quality standards - Pollution transport (from other areas/states) - Determining where air quality monitors should be located The Bureau computes air pollution impacts from sources such as power plants, compressor station engines, asphalt plants and rock crushing operations.

AIR DISPERSION MODELING Geo Resources Software Water Level O/W IF Meters ... Credits Industrial Emissions Air Plume Delineation The monitoring of industrial emissions to the atmosphere is changing rapidly in response to increased demands from regulators. Hardware, software and application techniques have all evolved. Keeping current with developments is a continual challenge. Research continues to show that airborne contaminants can be carried hundreds of miles from its source and can cause health and environmental problems on a regional or even global scale. In humans, airborne contaminants can cause burning eyes, irritated throats, difficulty with breathing, long-term damage to the respiratory and reproductive systems, cancer, and, in the most severe cases, death. Trees, lakes, crops, buildings, and statues can be damaged by air pollution. In the USA, the Clean Air Act of 1970 (amended in 1990), administered by the U.S. Environmental Protection Agency (EPA) sets and enforces air pollutant limits on sources such as power plants and industrial facilities to help protect against harmful health and environmental effects. Although the Clean Air Act is a Federal law, state and local agencies are responsible for implementing many of its requirements. Other countries with air pollution problems have put into place similar laws, directives, and initiates.

Software solutions for air dispersion models, traffic pollution models, contaminant emission modeling, industrial risk assessment models and emissions estimation. DISPER software: air pollution software, stack design , air dispersion modeling, stack testing , air dispersion software and combustion modeling The transport and dispersion of air pollutants in the air are influenced by many complex factors. Weather patterns and topographical conditions affect the way that pollutants are transported and dispersed in the air. The primary factors affecting transport and dispersion of pollutants are wind and stability. The winds are caused by differences in pressure between areas of the atmosphere. Differences in pressure cause air to move from high pressure areas to low pressure areas. Wind speed can affect the pollutant concentration in a selected area. In general, the higher the wind speed, the lower the pollutant concentration. The winds dilute pollutants and rapidly disperse them throughout the near areas. The DISPER air dispersion model is a steady-state Gaussian plume model which can be used to assess pollutant concentrations from wide variety of sources associated with an industrial complex, roads,...

htmlAdWH('93212816', '728', '90'); Main My First Home Page Air Dispersion Modeling Air dispersion modeling can be used to evaluate the movement of odor from a source and determine the extent and frequency of odor impacts on a surrounding community. Models are often used to evaluate the potential for odor impacts from proposed facilities as part of the siting process or to compare different mitigation efforts in order to determine the best odor mitigation solution for existing facilities. Using modeling, many scenarios can be considered at low cost, and the modeling effort may save a facility the expense of constructing an inappropriately sited or designed facility and the hardship associated with public opposition. The model that is typically used for this work is the EPA recommended ISCST3 model. This model takes local topographical and meteorological data into account and combines this information with emissions concentrations, site layout, operational parameters, and source dimensions to determine the movement of odors from the site. Modeling results are expressed as a series of isopleths, or concentric circles, which show the maximum concentration of odor that is

Air Dispersion Modeling Air dispersion modeling is used to predict off-property concentrations resulting from emissions of air pollution. Equations and algorithms representing atmospheric processes are incorporated into various computer models, which enable the modeler to enter pertinent data, such as emission rates and distance parameters. The model calculates atmospheric concentrations of a pollutant at specific points, or receptors, near the source(s) being evaluated. Most state environmental agencies require some degree of modeling analysis as part of the air permit application process. It is important to determine the level of air pollution concentrations from an emissions source in order to evaluate the effect those emissions will have on the air quality in the vicinity of the source. Agency staff use modeling results to determine whether a facility is operating or will operate in compliance with state and federal standards, and whether its operation may result in negative health effects on persons living or working in the area. Type of Modeling Modeling generally falls into two categories: preliminary, or screen, modeling, and refined modeling. Preliminary modeling is used to determine whether refined modeling is necessary. Refined modeling requires more detailed input data and produces more accurate concentration estimates than preliminary modeling. EPA’s American Meteorological Society/Environmental Protection Agency Regulatory Model Improvement Committee model "AERMOD" is the primary model used for refined modeling. Several software companies offer packages that incorporate the AERMOD model and graphics to make the model easier to use.
