A total of ten (10) ambient air monitoring stations were identified based on the different existing land use pattern to study the ambient air quality along the project corridor. The ambient air quality in the corridor was found to be in compliance with the ambient air quality norms stipulated by CPCB/GPCB. The ambient air quality monitoring stations have been depicted in Figure 4-6. Talala Morbi Gondal Una Jasdan 4-9
