Calibration and Validation of PM-CEMS for 1st Phase Star Rating Industries

For the 1st phase of rollout, 20 industries from different sectors have been chosen and their PM-CEMS have been calibrated during May 2018. The Star Rating is based on two factors: emissions averaged over a month compared with permissible limit, and data availability as prescribed by CPCB guidelines. Industries sending less than 85% of data on daily basis will be considered as default as per CPCB guidelines and automatically be given a 1-star. This may be mentioned that 5-star is considered as the highest rating in this program. Gradually the program will cover all 135 industries under 17 categories of highly polluting industries after calibration and validation of PM-CEMS.
