September 18, 2005
Five workshops were offered on September 18, 2005, at the Marriott Crystal Gateway prior to the Air Quality V Conference.

Registration
On-site registration for the Preconference Workshops took place Sunday, September 18, 2005, from 7:30 a.m. to 5:00 p.m.

8:00 -9:30 a.m.	Workshop 1 Mercury in Coal and Speciation in Combustion Flue Gases This workshop provided information on the forms and abundance of mercury in coal and the components that impact mercury transformations and speciation flue gases.
9:45 - 11:15 a.m.	Workshop 2 Mercury Sampling and Measurement This workshop discussed the challenges of mercury sampling and measurement in combustion-derived flue gases. Emphasis was placed on mercury speciation using the Ontario Hydro method and online mercury analyzers.
11:30 a.m. - 1:00 p.m.	Workshop 3 Mercury Control - Power Plants Equipped with Particulate Control Only The aim of this workshop was to provide an overview of the methods used to control mercury in power plants equipped with particulate control technologies only. Results of pilot- and full-scale testing using sorbents and additives was discussed.
1:00 - 2:00 p.m.	Lunch on Your Own
2:00 - 3:30 p.m.	Workshop 4 Mercury Control - Power Plants Equipped with Scrubbers with and Without Selective Catalytic Reduction (SCR) for NOx Control This workshop discussed the use of oxidation, sorbents, and stabilization technologies to improve the capture of mercury in both wet and dry scrubbers. Emphasis was placed on the use of oxidation technologies to improve the capture of elemental mercury.
3:45 - 5:15 p.m.	Workshop 5 Fine Particulate and SO3 Aerosol Control Issues and Approaches This workshop briefly reviewed the issues related to fine particles in the atmosphere and then focused on fundamental dust properties and separation mechanisms, common practices for control, and new developments.

Presenters

•	Dr. Steve Benson, EERC Senior Research Manager, has performed research on inorganic transformations and ash behavior during combustion and gasification for the past 25 years. He currently develops projects and programs focused on power plant performance, environmental control systems, the fate of pollutants, computer modeling, and health issues.
•	Mr. Michael Holmes, EERC Deputy Associate Director for Research, is involved in research for a range of areas, including emission control (air toxics, SO2, NOx, H2S, and particulate), fuel processing for production of syngas and feed gas for fuel cells, and process development and economics for advanced energy systems.
•	Mr. Dennis Laudal, EERC Senior Research Advisor, is involved in program development related to mercury control and measurement. He is considered a leading expert on continuous mercury monitors. He is also involved in particulate measurement and control of SOx, NOx, and air toxics.
•	Mr. Stanley Miller, EERC Senior Research Manager for Environmental Technologies, manages an extensive program in air pollution characterization and control, including the study of the formation and properties of fine particulate matter and the application of appropriate economical control strategies based on particle properties.
•	Mr. John Pavlish, EERC Senior Research Advisor, has over 20 years of experience with advanced combustion systems, with expertise in regulatory issues regarding air toxins, international consulting, and research into advanced emission control technologies. He also serves as Director of the Center for Air Toxic Metals® Program at the EERC.
