"Are the Emissions/Waste generated by the company within the permissible limits given by CPCB/SPCB for the financial year being reported?

As already explained above, Power transmission project activities do not involve any direct emission/waste to environment. The only emission that can be attributed due to our activities is from operation of DG sets used intermittently as power backup. However, regular maintenance of DG sets are ensured to maintained their emission level well within the permissible limits prescribed by Pollution Control Board."
