5.1.2 Air Quality
- Existing ambient air quality at potential receptor (s) for parameters of SO2, NO2, CO, Suspended Particulate Matter (SPM) and other which considered significant should be measured and compared with National Ambient Air Quality Standards (NAAQS) and other internation standard (in case National Ambient Air Quality Standards does not have this parameter)
- Estimation of existing emission source of those air pollutants in study area of 5 km. around project site.
- Evaluation of how much more those air pollutants can be emitted from the industrial estate so that National Ambient Air Quality Standards at the potential receptors will not be violated. Meteorological data at least one year of daily wind speed and direction of the area of nearest meteorological station should be used for dispersion model.
- Odor problems should also be evaluated especially on passengers at Surat Thani Airport.
