CPCB orders shutdown of NCR units that skipped pollution-control upgrades

The Central Pollution Control Board has told pollution authorities in Delhi, Haryana, Uttar Pradesh and Rajasthan to shut industrial units that have not ordered or upgraded air pollution control devices. In an October 30 letter, it sought immediate show-cause notices to units violating the CAQM's revised emission norms, signalling tighter enforcement ahead of the winter pollution season.
