Every Industrial, Commercial unit which generates wastewater, emits air emissions, generates hazardous waste has to obtain prior permission from concerned Pollution Control Board in form of License/ NOC/ Consent To Establish (CTE), Consent To Operate (CTO) under Air and Water Act & Authorization under Hazardous Waste Rules.
Categorization of Industrial Sectors under Red, Orange, Green and White Category
CPCB has developed the criteria of categorization of industrial sectors based on the Pollution Index which is a function of the emissions (air pollutants), effluents (water pollutants), hazardous wastes generated and consumption of resources.
The Pollution Index PI of any industrial sector is a number from 0 to 100 and the increasing value of PI denotes the increasing degree of pollution load from the industrial sector. Based on the series of brain storming sessions among CPCB, SPCBs and MoEFCC , the following criteria on ‘Range of Pollution Index ‘for the purpose of categorization of industrial sectors is finalized.
o Industrial Sectors having Pollution Index score of 60 and above – RED CATEGORY
o Industrial Sectors having Pollution Index score of 41 to 59 – ORANGE CATEGORY
o Industrial Sectors having Pollution Index score of 21 to 40 – GREEN CATEGORY
o Industrial Sectors having Pollution Index score incl. & upto 20 - WHITE CATEGORY
