Punjab Pollution Control Board has identified the industrial cluster of Mandi Gobindgarh and Khanna as one of the most critically polluted areas in the state.
PPCB Chairman Ravinder Singh said the the rolling mills and forging units located in these areas are the major source of air pollution.
He said that as a part of corrective measures, Punjab Pollution control Board has persuaded these units to switch over to greener fuels like CNG.
Singh said that as a result, more than 200 units have already entered into an agreement with Gas Authority of India Limited for this purpose.
The PPCB Chairman said all the 334 air polluting large- scale industries requiring air pollution control devices (APCD) have installed the treatment devices while 163 air polluting medium-scale industries have installed the treatment devices.
He further said only 0.28 per cent of small-scale units are left which have not installed APCD.
