The Central Pollution Control Board (CPCB) has directed three cement manufacturing units in Telangana state to shut down their operations and issued show-cause notices to 11 others, seeking replies as to why they should not be shut down for non-compliance with pollution control norms. The units that were issued closure notices belong to Kakatiya Cements in Nalgonda, Mancherial Cements in Mancherial and the public-sector Cement Corporation of India at Tandur, the New Indian Express reports.

The present crackdown comes after serving of several notices to polluting units across the country, asking them to install online pollution monitoring systems which are to be connected to the CPCB as well as State Pollution Control Board servers to ensure real-time monitoring of pollution emission of industries.

Cement units were sent show-cause notices also for not taking steps as stipulated by CPCB for reducing the pollution emissions to new standards. Even after two years, many factories in the country are yet to install the online pollution monitoring systems.
