Source Types for AERMOD
When is it appropriate to use one source type over another in AERMOD
In this series, we will be examining the behavior and appropriateness of the various emission source types available in the AERMOD dispersion model. When you represent a real-world emission source in the AERMOD dispersion model, which source type do you select and what went into your decision making process to choose one type over another?
In my 20 year career with the TCEQ, my priority was to give guidance on dispersion modeling, so customers could provide an air quality analysis that the agency could approve. With decreasing agency resources and increasing regulatory demands, review timeframes were becoming extremely important for the agency and its customers. To expedite the review process while increasing the quality, I designed and developed tools to standardize and automate the review of air quality modeling analyses. The result was a more comprehensive and efficient process for agency staff and expeditious reviews for the regulated community.
From what I learned as a regulator, I wanted to provide the same level of automation for those compiling air quality analyses to submit to the TCEQ. Since I designed the system, I know the specifications and content necessary to take advantage of TCEQ’s system to quickly review and approve your analysis.
