A bench headed by NGT Chairperson Justice Swatanter Kumar ordered Delhi, Haryana, Rajasthan, Uttar Pradesh and Uttarakhand governments to file an affidavit and inform it about the mechanism of disposal of such hazardous waste.
"State of Uttarakhand, Uttar Pradesh, Delhi and Rajasthan will file complete independent statements as to how many industries are granted authorisation for dealing with hazardous waste and how they are disposing their hazardous waste within two weeks.
The matter is now listed for next hearing on September 16.
The tribunal had earlier directed the central and Uttar Pradesh pollution control boards to jointly inspect Rathi Steel and Power Ltd's plant at Ghaziabad for alleged failure to take steps to control air and water pollution.
NGT's direction came on a plea by Ghaziabad resident Rajiv Narayan, who had alleged that rapid development of industries there has resulted in acute air and water pollution which is causing severe health problems to the city's dwellers.
