AERMOD Modeling for Permits is Providence/Oris Training’s introductory course in air modeling for industrial permitting and other regulatory applications. Most modeling scenarios, from state permits to PSD modeling to risk assessments, use techniques taught in AERMOD Modeling for Permits.

AERMOD Modeling for Permits has been a continuous highlight of Providence/Oris Training. Its popularity is reflected in the number of companies who regularly send their new modelers to “learn from the experts” at Providence/Oris Training. Anyone from new modelers to somewhat more experienced modelers who want to brush up on their skills will benefit from AERMOD Modeling for Permits.

Like other Providence/Oris Training courses, AERMOD Modeling for Permits teaches students practical modeling methods and strategies. We don’t just stress theory. After all, when that big modeling project looms, knowing how to organize, manage and model the project is a lot more important than how to derive modeling equations!

In addition, we believe in the concept of “learning by doing.” We intersperse lectures with hands-on exercises, allowing the student to immediately practice what has been discussed in class. We feel this approach works better than a “day of lecture, day of lab” type of class.

Day One.  We introduce students to some of the basic concepts of modeling, fundamentals we believe are important for any modeler. These include the National Ambient Air Quality Standards, averaging periods and how to compare model results with standards.

Then, we introduce some of the things the modeler will need to know for his or her project before the computer even gets switched on. This includes how to select and interpret meteorological data and how to properly set up receptor networks. Students will process NED terrain data and run AERMAP. We’ll also review some of the modeling guidance and requirements for local states, often including presentations from the state or local agency’s own modelers.

Day Two.  We’ll focus on actual models and modeling strategies, including the latest guidance from U.S. EPA. Current methods and guidance on modeling are presented. We then dive into refined modeling strategies, including placing receptors, entering source data and GEP and building downwash data (BPIP & BPIP-Prime). We also look at how to create high-quality graphics for use in your modeling report. All along, hands-on exercises help reinforce the subjects presented.

Finally, we wrap things up by “putting it all together.” Our final modeling exercise uses AERMOD and our BEEST for Windows enhanced user interface.

By the end of AERMOD Modeling for Permits, students should be prepared to return to the office, and, with a little practice, perform most modeling studies on their own.

To summarize, AERMOD Modeling for Permits includes:

• Basics of computer modeling
• Fundamentals of modeling & air pollution meteorology
• Overview of state and federal modeling guidance
• GEP building downwash & BPIP, BPIP-Prime
• Refined modeling with AERMOD
• Receptor grid considerations and AERMAP
• Graphics
• Hands-on exercises
