Operators of cement plants are required to install continuous emission monitors (CEMs) for specified key emissions including particulates. The CEMs undergo daily internal calibration checks and a mandatory independent quality assurance check in accordance with the relevant British standard. Operators provide the Environment Agency with records of each measured daily average for particulates.
