Mark your calendars for our April AWMA-RMSS meeting on Thursday, April 21st, at the conference room of the 1801 California Street Building (previously CenturyLink Building) in downtown Denver. Our guest speaker will be Sergio Guerra of CPP Wind Engineering and his talk is titled: “Highlights from the Guideline on Air Quality Models Conference.”

Time:  11:30 lunch (no cost); 11:50 welcome and introductions; noon presentation

Place: Main floor conference room of the 1801 California Street Building (previously CenturyLink Building) in downtown Denver.

The meeting location is at the conference room in the main floor of the  1801 California Street Building (previously CenturyLink Building).

Sergio A. Guerra, PhD, is an environmental engineer with over 15 years of experience in air quality. Sergio’s expertise in research, regulations, and consulting gives him a unique insight into the interaction of the theoretical and practical aspects of air quality.  This experience is at the core of his interest in advanced methods to achieve accurate results from regulatory tools such as AERMOD. Sergio delivers presentations about his research at local and national forums of technical and non-technical audiences. His research has been published in the EM Magazine, the Journal of Air and Waste Management Association and the proceedings of the annual AWMA conferences.  Sergio holds a Ph.D. in Environmental Engineering from the University of Kansas, where he performed statistical analyses of continuous emission data. He earned an M.S. in Environmental Engineering and B.S. in Civil Engineering from the same university.

At CPP Sergio leads the air permitting services, assisting industrial clients with their regulatory and dispersion modeling needs, from the planning stages of a project to permit issuance. Sergio also assists clients in performing Equivalent Building Dimension (EBD) studies to refine building dimension inputs and achieve more accurate results in AERMOD.  Sergio has over seven years of regulatory experience  stemming from his work as a regulator in the State of Kansas and as an environmental consultant assisting clients around the country.  His industrial clients have included manufacturing, power plants, foundries, oil processing, silica sand processing, pulp and paper, and oil and gas facilities.

ABSTRACT: The revision of the Guideline on AQ Models (Appendix W) will prompt many changes in the way dispersion modeling is conducted for regulatory purposes.  Some of the changes to the Guideline include enhancements and bug fixes to the AERMOD modeling system, new screening techniques to address ozone and secondary PM2.5, delisting CALPUFF as the preferred long-range transport model, and updates on the use of meteorological input data. These changes will have a significant impact on the regulated community.  In anticipation of these updates, the Air & Waste Management Association will hold its 6th Specialty Conference: “Guideline on Air Quality Models: The New Path” to provide a technical forum to discuss the Guideline.  This talk will cover the main highlights from this conference including the presentations from EPA on the status and future direction of the Guideline.  Come learn how these changes may impact dispersion modeling evaluations for short and long range transport.
