It is important to understand how  these  pollutants  from  coal-fired  thermal  power  plants  disperse  in  the  ambient atmosphere. This study examines the air pollution condition at a proposed TPP and applies an  air  quality model,  the EPA  approved  dispersion  model of AERMOD,to  predict  the ambient air pollution concentrations resulted from different  emission scenarios. The stack emission rates from the power plant were calculated to provide the input emission data for the  modeling. The  meteorology data  were  taken  from  MM5  model, the  prognostic meteorology  model for  2008  year.Ground  level  concentrations  of  pollutants  including oxides  of  nitrogen  (NOx),  oxides  of  sulfur  (SOx),particulate  matter  (PM)  were  estimated by the  model  under  three  fuel-control devices  scenarios.  The  results  show  that  if  coal  is used  as  the  main  fuel  with  the  control  devices  of ESP,Sea-water  FGD  and  Low  NOx Burner then  only  PM10 and  SO2 would  meet  the Vietnamese  national  ambient  air  quality standards and  WHO  ambient  air  quality  guidelines. Only  when  SCR  is  installed  for  NOx emission control are all 3 pollutants would meet the standards. If natural gasis used as the main fuel in combination with low-NOx burner then the emission of PM10 and SO2 would largely  eliminated.  The  ambient  air  levels  of  all  3  pollutants  would  be  well  below  the standards. Under all 3 scenarios the levels simulated for the populated areas and sensitive areas  were  found  below  the  standards  suggesting  insignificant  impacts  from  the  proposed power plant. The model results under different emission scenarios can serve as the basis to suggest the emission control measures to improve the air quality in the study area 0aCoal-fired power plantsxEnvironmental aspectszVietnam 0aAirxPollutionzVietnam 0aEnvironmental impact analysiszVietnam1 aNguyen, Thi Kim Oanh,eChairperson1 aVisvanathan, C.,eExamination Committee1 aShipin, Oleg V.,eExamination Committee2 aPower Engineering Consulting, Vietnam,eScholarship donor2 aAsian Institute of Technology.tResearch studies project report ;vno.
