FREQUENCY OF MONITORING AND PARAMETERS FOR

POST- PRJECT ENVIRONMENTAL MONITORING

 

1. AIR QUALITY MONITORING: (As per Gazette Notification GSR 742 (E) dt:  25.9.2000)

 

Parameters:

 

Ø         Total Suspended particulate matter (TSPM)

Ø         Respirable Particulate Matter (RPM) (size less than 10 Microns)

Ø         Sulphur Dioxide (SO2)

Ø         Oxides of Nitrogen (NOx)

 

Frequency

 

  1. Air quality monitoring at a frequency of once in a fortnight (24 hourly sampling) at the identified locations near the dust generating sources.

 

  1. As a result of monthly monitoring, if it is found that the concentration of the pollutants is less than the 50% of the specified standards for three consecutive months, then the sampling frequency may be shifted to two days in a quarter year.

 

  1. In case the value has exceeded the specified standards, the air quality sampling shall be done twice in a week. If the results of four consecutive weeks indicate that the concentration of pollutants is within the specified standards, then fortnightly monitoring may be reverted to.
