He has served as a member of the ATSAC since its inception in 2005 and was elected Chair of the Committee in May 2008. He holds a bachelor's degree in Chemistry and a doctorate degree in Physical Chemistry. His areas of expertise include risk assessment, air dispersion modeling, air receptor modeling, environmental regulatory review and air quality permitting. Over his 19 year career as an environmental consultant, Dr. Patterson has completed numerous air quality risk assessments in accordance with U.S. EPA guidance for plywood and composite wood products manufacturing facilities, human health risk assessments under the California AB2588 program, multi-media contaminated site human health risk assessments, and a two-year comprehensive human health risk assessment for the Lawrence Berkeley National Laboratory to meet California Environmental Quality Act requirements.

Dr. Lambert has served as a member of the ATSAC since its inception. He is an Associate Professor in the Department of Public Health and Preventive Medicine at Oregon Health and Science University (OHSU). From 1987-2000, he held faculty and research positions at the University of New Mexico School of Medicine. He received his Ph.D. from the Department of Epidemiology and Environmental Analysis at the University of California, Irvine and a BA degree from the Department of Biology at the University of California, Los Angeles.

His areas of expertise are air pollution epidemiology, exposure assessment, toxicology, and biostatistics. He has served on a number of advisory/regulatory committees, including Chair of the City of Albuquerque/Bernalillo County Air Quality Control Board, a principal author of state of the science reviews for the American Thoracic Society's Environmental Health Committee, and as member of the Childhood Lead Poisoning Taskforce, Children's Environmental Improvement Project, and Turning Point Environmental Health Initiative, in New Mexico. Currently, he is Chair of the Board of Directors for the Josiah Hill III Clinic in Portland. His community service has been recognized by several organizations, including the Clean Air Award of the American Lung Association of New Mexico and the Lifesaver Award of the New Mexico Chapter of the American Cancer Society.

Dr. Norville is an Associate Atmospheric Scientist and project manager at Air Sciences Inc. in Portland, Oregon. He also is an original member of the ATSAC. He specializes in air quality dispersion modeling, data analysis, and model development. He has considerable experience with a wide variety of models for a number of different public and private sector modeling applications. Applications include regulatory permit modeling, risk assessments, and environmental impact statements; dust fall and deposition studies; accidental release dispersion modeling; visibility modeling; water vapor cloud assessments; odor assessments; transportation conformity and hot spots dispersion modeling; meteorological data processing and assessments; specialized modeling; and custom model development. He has provided modeling assistance to a number of industrial clients, including aluminum producers, wood product facilities, pulp and paper facilities, metal processors, cement plants, mining operations, food producers, electric power producers, composting facilities, and waste treatment facilities.

Dr. Norville is experienced with risk assessment methods and applications and has worked on a variety of different risk and toxics projects, including EPA superfund sites, public municipalities, and private industries across the United States. He holds a Ph.D. degree in geophysics from the University of Washington and a B.S. degree in physics from the California Polytechnic University, San Luis Obispo.

Ms. Kreitzer received a B.S. degree in chemical engineering from Oregon State University and has been employed as an air quality engineer, first as a consultant and more recently as an air quality regulator. She is also an original ATSAC member. Her relevant engineering experience includes knowledge of sources of toxic emissions to the air, emission control strategies and current and future EPA regulations affecting toxics air emissions.

For the past six years she has worked for the Southwest Clean Air Agency (SWCAA) in Vancouver, Washington and has been the air toxics coordinator at SWCAA since 2000. In addition, her duties include writing Air Discharge Permits for industrial facilities, inspecting industrial facilities and determining compliance with all applicable air regulations including Washington’s toxic rule "Controls for New Sources of Toxic Air Pollutants." In 2002, she participated as a member of Washington's Mercury Chemical Action Plan Advisory Committee and assisted in the development of a plan to reduce mercury in the state of Washington.

Dean B. Atkinson is an Associate Professor of Chemistry at Portland State University in Portland, OR. He received his Ph.D. in Physical Chemistry from the University of Arizona in Tucson in 1995, where he studied the low-temperature kinetics of atmospherically relevant reactions (primarily involving OH radicals) with Dr. Mark A. Smith. He had a two year NRC Postdoctoral Research Assistantship at NIST in Gaithersburg, MD, where he worked with Dr. Jeffrey W. Hudgens on methods for measuring reaction kinetics of free radical reactions, predominantly using pulsed laser photolysis/cavity ring-down spectroscopy. After starting at PSU, he built on that work and became one of the acknowledged experts in the application of the cavity ring-down method, particularly as applied to environmentally related measurements. Since much of his work at PSU has centered on atmospheric chemistry and physics, he has developed some expertise in this area, particularly in methods used to measure atmospheric species (e.g., trace gases, radicals, particulate matter.) He is familiar with the methods used to model the atmosphere, although his research has not involved the application of those methods to date.

The Atkinson group is currently funded by NOAA to produce a new type of airborne cavity ring-down instrument for measuring the optical properties of the aerosol aloft. The measurements made possible by this instrument should help to clarify both the direct and indirect radiative forcings associated with particulate matter, currently the largest single unknown in the estimation of global climate change. A prototype of the instrument was used for an EPA funded field study in Portland investigating the ambient aerosol optical properties and whether they can be used as a "signature" for diesel PM. This instrument was also used in the TRAMP (TexAQS II Radical and Aerosol Monitoring Project) portion of the TexAQS II field intensive during the summer of 2006.

Current research projects focus on the use of the cavity ring-down technique to investigate air quality and climate change in the context of aerosol effects and the measurement of ambient atmospheric benzene levels in Portland.

Dave Farrer is a public health toxicologist for the Oregon Department of Human Resources where he has worked for two years on human health risk assessment, risk communication, and production of public health assessment documents for the general public, with a special focus on Superfund and other hazardous waste sites. Much of that work has been providing assistance to Oregon DEQ and EPA. He received his BS degree from Brigham Young and his MS and PhD in Toxicology from the University of Rochester and has authored several peer-reviewed and numerous government publications. He has been an Associate Member of the Society of Toxicology since 2002.

Ms. Peterson is currently employed as an associate engineer with Hoefler Consulting Group, located in Salem. She holds a bachelor's degree in Chemical Engineering from Lafayette College. She has six years of relevant experience which includes air permitting, regulatory compliance, emission control strategies, and knowledge of Federal Reference source testing methods. She has been an active member of the Air and Waste Management Association, recently as Vice Chair of the Oregon Chapter and Secretary of the Pacific Northwest International Section. Starting in 2010, Ms. Peterson will serve a three year term as a Director on the Air and Waste Management Association's Board of Directors.
