The National Green Tribunal has slapped a penalty of Rs.25 crore on Adani-Hazira Port Pvt Ltd and its associate Hajira Infrastructure Pvt Ltd for carrying out work at their Hazira-based port near Surat without acquiring environment clearance. The Pune-based western zone bench of the NGT also ruled that the environment clearance (EC), granted by MoEF, in 2013 for further development of the port at Hazira, is illegal and set it aside.
