Gurugram: A month after the Central Pollution Control Board (CPCB) ordered the closure of industries that are not using PNG, members of Gurugrams industrial association on Friday met Union environment minister Prakash Javadekar raising their concerns over making the use of PNG mandatory for industries. They have also asked the minister to give them time and subsidy for shifting to PNG. The members also informed the minister that the cost of conversion of boilers from other fuel to PNG would cost them a huge. Explaining the cost of conversion, an industrialist said it was not the same for all units as it depended on the size of the boiler. "For example, if a boilers size is 70 tonnes, its conversion cost to PNG (depending on availability) will be approximately Rs 4 crore, whereas for the same boiler the coal cost will be around Rs 1 crore," he explained. The industrialists said that after the Supreme Courts 2017 ban on the use of pet coke, they switched to coal by modifying their boilers which involved substantial capital cost running into lakhs and now switching to PNG would again cost them a huge amount. "Till October 2017, the majority of the units in NCR were running their boilers either on pet coke or furnace oil or other permissible fuels. After the SC ban, the industries switched to coal by modifying their boilers. Then, they instructed us to put up real-time online air and water monitoring system. We complied with the directions. Now they want industries to switch to PNG. The industry is also going through a bad phase. We too are concerned about the environment, but why is industry expected to bear such huge cost every time," said an industrialist Over 800 such units have been issued notices. Moreover, based on the evaluation, the HSPCB has also categorised industries into various zones based on the pollutions of these units. Around 230 units have been placed under the red category the highest level for those causing maximum pollution. Next, in line are 360 units that have been placed under the orange category. Less than 100 industries have been placed under the green category which is these industries are not contributing to polluting citys air.
