Consulting firm based in Brisbane, Australia that offers air dispersion modeling services, using these models AUSPLUME, AUSMET/AUSPUFF, LADM, TAPM, CALMET/CALPUFF, and the U.S. EPA's ISC models.
Industrial Dispersion Modelling The modelling of the dispersion of air pollutants from an industrial source can be broken down into several steps: Source Identification Emission rates of pollutants can often be obtained from environmental handbooks, journals and studies for similar plant. The United States EPA has published generic emission factors for a wide variety of industries, and similar factors have also been published as part of the National Pollutant Inventory study in Australia. If these are not available or sufficiently accurate, chemical process flowcharts and control specifications can be used, or measurements made for existing similar plant. Major air pollutants usually considered include dust (particulates) due to incompletely burned fuel or process byproducts, nitrogen oxides (mainly due to combination of atmospheric oxygen and nitrogen at high temperatures) and sulphur dioxide (mainly due to the burning of fuel containing quantities of sulphur).

Who we are
Stone Lions Environmental Corporation was founded in April, 1993. We are an environmental consulting firm specializing in air pollution evaluations related to a variety of industrial facilities. In addition, we research potential health effects that result from community exposure to a wide variety of toxic chemicals. Much of our work is done in the context of complex civil litigation.
Where we are
Our primary offices are located in Rolling Hills Estates, California. We have affiliated operations in Houston, Texas.
What we do
We evaluate refining, petrochemical, and chemical operations, and the associated toxic exposure problems. We employ a variety of chemical engineering techniques to perform those evaluations. We develop emissions inventories, and analyze source and meteorological data in order to define current and past community exposures. We then integrate this data into a variety of computer models, which predict the atmospheric dispersion of toxic chemicals from the source of emissions. Our modeling protocols are consistent with EPA guidelines and standard air pollution engineering practices.

Air Quality and Comparative Exposure: A Parcel-Level Cumulative Risk Analysis in Providence, Rhode Island
AIR DISPERSION MODELING DEFINITION According to the Environmental Protection Agency ( USEPA) , dispersion modeling is "a mathematical representation of the transport and diffusion processes that occur in the atmosphere." is the model currently used by USEPA for regulatory screening of new permit applications and New Source Review. SCREEN3 is based on Gaussian plume algorithms and estimates worst-case scenario ambient impacts from point, volume, and area sources by incorporating general meteorological conditions . USEPA uses this model as a conservative first run screening tool, followed by more refined modeling in areas determined by SCREEN3 to be of potential concern. Inputs to SCREEN3 include a choice of source type (point, flare, volume or area source), urban or rural terrain, emission rate, and building size. If the source has a stack, stack height, stack diameter, exit velocity, flow rate, and exit temperature must also be included. Output from the model comes in the form of a dispersion curve showing the change in chemical concentration as distance from the facility increases ( see example SCREEN3 output ). The model incorporates worst case meteorology by determining which combination of wind speed and stability class combines with facility information to create the worst case weather scenario.

96. P1.8: Air Dispersion Modeling Via The Internet
P1.8 air dispersion modeling VIA THE INTERNET PAPER WITHDRAWN. The Internethas had a profound effect on air dispersion modeling practice.
11th Joint Conference on the Applications of Air Pollution Meteorology with the Air and Waste Management Association
Technological advancements have revolutionized air dispersion modeling practice over the last 15 years. Through the 1980s and 1990s, computers became faster, smaller, and easier to use. Major permitting work could be completed more quickly. Software utility programs became readily available, improving the ability of modelers to process and visualize data. The Internet has had a profound effect on air dispersion modeling practice. Already, the tools and information that dispersion modelers use, such as the models, meteorological data and topographical maps, can be obtained over the Internet. Model users now typically either download models such as ISCST3 from the USEPA SCRAM web page, or purchase dispersion model suites from software firms. Thus, models have become distributed across many local computers. This paper examines the feasibility of running air dispersion models such as ISCST3 or AERMOD over the Internet. Under a centralized model, users would no longer need to run EPA FORTRAN code locally, or purchase and install proprietary software on a local computer. Instead, users would interact with an Internet interface, uploading model input data or entering data into forms, and retrieving or downloading model output results. Model code, not necessarily FORTRAN-based code, would be run remotely on very fast servers.
