New Delhi : Environment Minister Prakash Javadekar on Monday claimed a major revolution of putting all highly polluting industries in 17 categories under 24×7 monitoring by forcing them to install continuous effluent and emission equipment for online monitoring.

As many as 1475 of them have already installed these devices and 805 more shall have them by this month end, thus putting 2280 industries in the self-monitoring mode round the clock from April 1, Javadekar said, pointing out that the earlier method of physical sampling and lab testing was found to be inadequate as it could not capture pollution levels all 24 hours.

His ministry had identified a total of 3145 industries that are highly polluting.

While 321 industries are currently closed and orders are being issued to ensure that they reopen only after installation of these devices. Closure orders have been also issued to 141 industries and action is being initiated against the remaining 403 industries.

Power plants, oil refineries and petrochemical factories have been allowed time up to June 30 to install the online monitoring systems as they require complete shutdown to attach these systems.

The 24×7 continuous monitoring systems cover emission parameters like PM (Particulate Matter), SO2 (Sulphur Di-oxide), NO2 (Nitrogen Di-oxide), CO (Carbon mono-oxide), Ammonia, etc. and effluent parameters like flow, pH, BOD (Bio-chemical oxygen demand), COD (chemical oxygen demand), TSS (Total suspended solid), Ammonical Nitrogen etc.

Data connectivity has been established with 1101 units with the Central Pollution Control Board (CPCB) and SMS alerts and emails are automatically generated whenever standards are exceeded for more than 15 minutes.

On an average, around 1000 SMSs for exceedances are being generated on daily basis besides emails and these SMSs are being sent to the concerned industry as well as CPCB and the State Pollution Control Board.

Industries are supposed to take action immediately to control emission and effluent and report this action taken on an email id
