India: Chettinad Cement’s Karikkali plant in Tamil Nadu has been issued a show cause notice by the Central Pollution Control Board (CPCB) for exceeding particulate matter emissions by more than three times the limit. An inspection following Online Continuous Emission Monitoring Systems (OCEMS) data found emissions of 91.2mg/Nm3, according to the New Indian Express. The limit is 30mg/Nm3. The CPCB also found discrepancies with the OCEMS data due to poor instrument calibration.
