Georgia Environmental Protection Division Links Between Air Pollution in Georgia and Cindy Crawford: Shortness of breath, increased heart rates, and what GA EPD plans to do about it!! Jim Boylan, Amit Marmur, Jim Kelly Maudood Khan, and Dan Cohan (Georgia Environmental Protection Division) Georgia Air Quality Summit Atlanta, GA - May 4, 2006

Georgia Environmental Protection Division Policy Development  Identify menu of control options to be considered  Consider regulatory and practical implications along with costs, benefits, & sensitivities  Develop and implement regulations and policies Air Quality Modeling  Meteorology, emissions & photochemistry for base & future  Sensitivity analysis of responses to various controls by location and species  Impact (relative reduction factor) of overall strategy Cost Assessment  Evaluate cost-effectiveness ($/ton) of each control option Benefit Assessment  Evaluate health and other benefits of control strategy Individual measures, overall strategy to model Sensitivity to controls; Impact & attainment (Y/N) of overall strategy Iterative search for additional measures Control measures to be evaluated Estimated $/ton of each measure Modeled base & controlled pollutant concentrations Morbidity/mortality averted, visibility improved, etc. due to control strategy Integrated Approach to Air Quality Attainment
