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
Integrated Approach to Air Quality Attainment Individual measures, overall strategy to model • 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 Sensitivity to controls; Impact & attainment (Y/N) of overall strategy Iterative search for additional measures Control measures to be evaluated Estimated $/ton of each measure Modeled base & controlled pollutant concentrations Morbidity/mortality averted, visibility improved, etc. due to control strategy • Benefit Assessment • Evaluate health and other benefits of control strategy • Cost Assessment • Evaluate cost-effectiveness ($/ton) of each control option Georgia Environmental Protection Division
Non-Attainment in Georgia • 8-hour ozone standard (85 ppb): Atlanta, Macon • Annual PM2.5 standard (15 g/m3): Atlanta, Macon, Floyd county, Chattanooga Ozone non-attainment areas PM2.5 non-attainment areas Georgia Environmental Protection Division
