American Association of State Climatologists, 41th Annual Meeting. Santa Fe, July 1, 2016 Maryland Healthy Air Act and Observed Changes in Air Quality The Maryland Healthy Air Act was developed with the purpose of bringing Maryland into attainment with the National Ambient Air Quality Standards for ozone and fine particulate matter by the federal deadline of The Healthy Air Act impacts Maryland’s largest coal-burning power plants, which account for over 95% of the state’s power plant emissions.

Due to recent local and national regulations of power plant SO2 emissions, summertime tropospheric SO2 columns, PM2.5 levels, and AOD decreased substantially over the eastern United States. The Healthy Air Act, implemented in Maryland in 2009–2010, provided an exceptional opportunity to test the impact of a step change in local emissions on ambient pollution levels. This Maryland regulation reduced in-state power plant emissions of SO2 by ∼ 90%; long-term aircraft measurements, surface observations, and satellite products showed a reduction in column SO2 of ∼ 50%, while PM2.5 and AOD showed a reduction of ∼ 25%. Even though the regulations on Maryland power plants successfully reduced local SO2 pollution, PM pollution in Maryland is more regional, and regional/national regulations are needed for further improvement of air quality.

9 Maryland Vital Statistics. Annual Report 2014 Medical statistics displays noticeable decrease in the MD citizens’ death rate after This decrease is consistent with expected result of MD Healthy Air Act. Nevertheless, the same trend in mortality is also relevant to current progress in medical science and to improving of public access to medical service, and other factors.
