Khattar said that environmental clearance would also be given to 15 long-established formaldehyde industrial units so that those industrial units could uninterruptedly run their operations. Notably, coal and other conventional energy sources would now be replaced with CNG, PNG and LPG in industrial units located in national capital region districts. CNG, PNG, and LPG pipeline supply has not yet reached eight district areas of Haryana coming under NCR, and with the decision of continuation of exemption given to industrial units, now these units too will be able to get CNG, PNG, and LPG supply.
