In its notification, MoEF had declared that the ESZ in the sanctuary will be the area up to 100 m from the eastern, western and southern boundary and up to 1.27 km from the northern boundary of the sanctuary, which extends up to DND flyover across the riverbed situated in Uttar Pradesh's Gautam Buddh Nagar district and southeast district of NCT Delhi.
The directions came while hearing a plea filed by environmentalist Paramveer Singh challenging the notification on the ground that MoEF has failed to comply with directions by the tribunal in relation to the protection of eco-system of the Okhla sanctuary.
Contending that the notification is "nothing but death knell" for the sanctuary, Singh has sought directions to produce all the documents with regard to the decision making process of Eco Sensitive Zone of the sanctuary.
"That notifying an area up to 100 m from eastern, western and southern boundary and area up to 1.27 km from the northern boundary of the Okhla Bird Sanctuary in Uttar Pradesh and NCT Delhi as Eco Sensitive Zone is highly irrational and the respondents have failed to examine its ecological impact on the sanctuary," it said.
