A bench headed by NGT Chairperson Justice Swatanter Kumar issued notices to the UP government, Central Pollution Control Board, state pollution control board, slaughterhouse Frigerio Conserva Allana Pvt Ltd, Central Ground Water Authority, Aligarh District Magistrate while seeking their reply before July 19.
The tribunal, however, refused to appoint a local commissioner in the case to carry out the inspection at the premises of the meat supplier unit.
The order came on a plea filed by an environment activist Shailesh Singh against the slaughterhouse situated at Talaspur Khurd under Koal tehsil of Aligarh.
The petitioner also submitted photographs and videos before the bench showing the condition of nearby areas due to the dumping of waste.
In 2015, the NGT had imposed a ban on all illegal slaughter houses in Uttar Pradesh and directed state authorities to ensure there is proper regulation of meat shops.
The tribunal had said slaughter houses which do not have permission from the UP Pollution Control Board (UPPCB) and/or environmental clearance from State Level Environment Impact Assessment Authority (SEIAA) besides permissions from local authorities will not be allowed to operate either in open or shops.
