A bench headed by NGT chairperson Justice Swantanter Kumar directed the committee comprising Delhi Pollution Control Committee (DPCC), Delhi Jal Board (DJB) and an officer from Delhi government to weigh the entire clay and sand.
"We constitute a committee of DPCC, DJB and an officer from NCT of Delhi who shall first weigh the entire clay-cum- sand that is stated to be lying on the river bed thereafter it will be permitted to be lifted.
The matter was fixed for next hearing on January 27, 2015.
The tribunal also made it clear that the royalty would be computed on actual content of clay and sand in the dredging material.
The order came after the counsel appearing for DJB informed the bench that around 70,000 cubic metre of clay and sand was lying on the river bed which should be permitted to be disposed by the contractor.
The order came over a petition by Rahul Nagar seeking a complete ban on illegal sand mining in the capital without obtaining environmental clearance.
"Illegal mining is not only in contravention of the Environment (Protection) Act, 1986, but also of order and directions of Supreme Court and directions of National Green Tribunal," Nagar had said in his plea.
The petitioner had claimed that the sand mining mafia has begun to trespass private agricultural fields located near flood plains even though such activity, without any environmental clearance, is banned.
