5.1.2 Air quality
-Existing ambient air quality at potential receptor (s) for paramerters of SO2 ,NO, CO, suspended particulate matter (SPM) and others which considered significant should be measured and compared with national ambient air quality standards (NAAQS) and other internation standard (in case NAAQS 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 NAAQS 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.
