Justice V Ramasubramanian and Justice V M Velumani said the NGT's order is valid only for six months, which would end on August 23. Thereafter quarry operators should obtain environmental clearances based on the new guidelines issued by the Ministry of Environment and Forests which came into force from December 24, 2013.
"Under the circumstances, the writ petitions are dismissed," the bench said.
Kollidam river Protection Welfare Sangam's president R Subramanian and social activist P Ettikkan had filed the PILs against the NGT's order and sought a direction to restrain sand quarry operation in 18 places in Karur, Tiruchirapalli, Thanjavur, Tiruvarur and Nagapattinam districts.
The bench had on April 30 passed interim orders restraining instream mining and mechanized mining in the quarry sites.

In 2012, Cauvery Neervala Aathara Pathukappu Sangam had filed a petition before the Bench, seeking a direction to restrain PWD from sand quarry operations.

Aggrieved over it, the matter went to NGT.
Meanwhile, the Union Ministry of Environment and Forests brought in new guidelines on mining activities that came into force on December 24, 2013.
