Pollution watch goes online 24x7

New Delhi:
India's apex pollution control agency is about to take on the role of "Big Brother" for industries, acquiring the capability for 24-hour surveillance of select factories through a network of sensors, communication channels and cameras.

The Union environment and forests ministry has launched a nationwide pollution tracking system that will allow the Central Pollution Control Board (CPCB) to continuously monitor the gas and liquid effluents discharged by select industrial units across the country.

"This is a big leap in tracking and managing industrial pollution in the country," environment and forests minister Prakash Javadekar said today, announcing details of the programme that he said was initiated by the Narendra Modi government last year.

While the central and state pollution control boards did periodically inspect industrial units, the process was seen as inefficient because the factories could "clean up and behave well" only during such inspections, an official said.

Under the new initiative, about 2,800 units from the chemical, fertiliser, pesticide, pharmaceutical, tannery and textile sectors, among others, have been asked to install sensors to monitor the levels of effluents in their gas and liquid discharges.

"We have learnt that more than 920 industrial units have already installed the pollution-monitoring sensors while others are doing so," Javadekar said.

The CPCB, he said, has started receiving online data from these sensors, enabling it to monitor the industrial units' compliance with pollution standards.

A network of communication channels connecting the factories to the CPCB will stream data relating to air pollutants such as particulate matter, carbon monoxide or sulphur dioxide as well as the various parameters that determine pollution levels of liquid effluents.

But the CPCB and the state boards will need to improve their human resources and technology infrastructure to rigorously track the vast amount of data that will eventually stream in through the network.

"We now have about 30 to 40 sector specialists who will track the data from the sensors but enforcement is under the states. The state boards will also need to link up and get enough people to do this," a senior CPCB official told The Telegraph.

When the pollution control agency finds the values of the pollutants rising beyond limits, text-message alerts would be sent to the industrial unit managers as well as the state boards, seeking corrective steps.

A senior CPCB official said that many industrial units had been asked to also install cameras equipped with night vision, pan, tilt and zoom facilities at select sites to determine how the units were managing their effluents.

"Given the bandwidth limitations, we can't get real-time online video recordings of these cameras but we've asked them to preserve them so that we can demand and watch them any time," the official said.
