The submission was made in the report of the nine-member committee set up by NGT to suggest measures to control water and air pollution, for solid waste management, water conservation, sanitation and hygiene, waste minimisation and better work practices by the eating joints.
The committee was set up while NGT was dealing with the issue of several Hauz Khas eateries operating without consent of the DPCC and discharging untreated waste.
The tribunal also said that any eating joint having any objection to the suggestions may inform it.
In its report, the panel said "Ironically while issuing licences/registration, none of the agencies, ask for consent of DPCC. Consequently, till date, only about 300 hotels/ restaurants have applied for consent under Air/Water Act from DPCC while thousands are operating without obtaining any consent from DPCC," it said.
"There is no denying the fact that some of these units are operating without obtaining consent from DPCC," the report stated, adding that consent to operate from DPCC be made mandatory by the registration issuing agencies, especially at the time of renewal of licence.
