The minister, in his written response, admitted that it does not have count of such illegal units in residential areas in the country, including inventory of such units in Delhi.
He said no inventorization of jeans dyeing factories operating illegally in residential areas had been undertaken by the environment ministry or the Central Pollution Control Board (CPCB).
The minister noted that the textile dyeing has been categorized as ‘Red’ category (highly polluting) industry which is required to obtain consent to establish/operate from concerned State Pollution Control Board or the Pollution Control Committee.
The TOI had in May reported about discharge of carcinogenic chemicals by cloth dyeing units, highlighting how the untreated effluents are even contaminating ground water which is the main source of drinking water in the area.
Responding to a question on the steps being taken by the government to check the pollution caused by dyeing factories, Harsh Vardhan said the Delhi government had directed that action would be taken by the Delhi Development Authority (DDA) and Municipal Corporation of Delhi (MCD) against industries operating in residential/non-conforming areas in violation of the Master Plan of Delhi.”In order to check pollution from dyeing industries, effluent standards for textile sectors have been notified under the provision of Environment (Protection) Act, 1986 which has prescribed standards for Chromium, Phenolic Compounds, Colour etc”, he said while admitting that the exposure to these chemicals, exceeding prescribed limit, can affect human health.
Taking suomotu cognisance of the TOI’s report, the Delhi High Court had earlier asked the CBI to probe the entire issue of the illegal jeans dyeing units and find out the complicity of officials, if any, in allowing such units in those residential areas. The CBI subsequently started its probe after registering a case on last Friday.
