CEMS- Selection, installation, certification, calibration/re-calibration, daily check, data recording, record keeping, compliance check, publish
• Device health check- daily 10.00 a.m.; zero drift • calibration verification- 3 months • Zero and span drift – every week • >85% data capture • Data verification/ calibration- 6 monthly by empanelled Lab• Compliance
Any exceedance- violation Data spikes (< 1 min)- not for avg Continuous exceedance upto 10% of norms,
o >30 mins- preventive action by industry o >60 mins- to inform SPCB/PCCs about preventive actiono Second time- closure
Frequent exceedance- > 5% of data/day- action by SPCBs/PCCs Industry fails to control emissions- closure as per SOP Start-up/shut down ( batch process for 30 mins)- not for avg
