Pursuant to direction modified under section -18(1)(b) of water (prevention & control of pollution) act, 1974 & the Air ( prevention & control of pollution) Act, 1981 regarding harmonization of classification of industrial sectors under RED/ORANGE/GREN/WHITE categories vide letter no. B-29012/ESS (CPA) / 2015-16 dated 07/03/2016 circulated file final report on revised categorization of industrial sectors under RED/ORANGE/GREN/WHITE has been evolved on basis of range of pollution potential of the industrial sector and grouping of the industrial sector based on the use of raw material, manufacturing process adopted and pollutants likely to be generated.
- Industrial sector having pollution index score of 60 and above – Red category
- Industrial sector having pollution index score of 41 and 59 - orange category
- Industrial sector having pollution index score of 21 and 40 - Green category
- Industrial sector having pollution index score of incl. & upto 20- White category
Whereas based on relative pollution index, the number of industries under various categories is as under:-
- The Red category of industrial sectors – 60
- The orange category of industrial sectors- 83
- The Green category of industrial sectors- 63 &
- The newly introduces White Category- 36
