Comprehensive Environnemental Pollution Index (CEPI)
Central Pollution Control Board (CPCB) in association with Indian Institute of Technology, New Delhi carried out an environmental assessment of industrial clusters across the India. Based on this, comprehensive environmental pollution index was calculated to identify polluted industrial clusters in the country. This was done to priorities planning needs to improve quality of environment in these industrial clusters. Total 88 industrial areas have been selected for this study.
Comprehensive Environmental Pollution Index (CEPI) is calculated considering four factors Namely Pollutants, Pathway, Receptor and additional high risk element. Each of these factors comprises Sub-factors. Details of which are given below:
This factor is calculated as A = A1 x A2
Where A1 is Presence of toxins and
A2 is Scale of industrial activities.
Maximum Score for this factor is considered as 30.
B) Pathway:This factor is calculated as B = B1 + B2 + B3
Where B1 is Pollutant concentration,
B2 is Impact on people and
B3 is Impact on Eco-geological feature.
Maximum Score for this factor is considered as 20.
C) Receptor:This factor is calculated as C = C1 x C2 + C3
Where C1 is Potentially affected population,
C2 is Level of exposure and
C3 is Risk of sensitive receptors.
Maximum Score for this factor is considered as 30.
D) Additional high risk element:This factor depends on inadequacy of pollution control measures for large scale, medium & small scale industries. It is cumulative of ETPs, CETPs, Air pollution control devices & unorganized waste disposal.
Maximum Score for this factor is considered as 20.
On the above basis score for these factors calculated as
Score = A + B + C +D = 30 + 20 + 30 + 20 = 100
CEPI based on above mentioned score is calculated for Air, Water and land.
Following table indicates the CEPI score for industrial areas/ clusters in descending order for the 88 locations in all over the India.

The last column of the table indicates the status of air, water and land environment in terms of subscript as Critical (c) / Severe (s) / Normal (n). When the total score is more than 60 pollution index is consider as Critical in the respective environmental component.(Ac means pollution level of environmental component “Air” is critical.)
Out of 88 industrial clusters 8 clusters belongs to Maharashtra these are namely Chandrapur, Dombivali, Aurangabad, Navi Mumbai, Tarapur, Nashik, Chembur, Pimpari-Chinchwad.

Ministry of Environment & Forest vide Office Memorandum J 11013/ 52010- IA. II (I) dated 13 January 2010 imposes temporary restriction on developmental projects in identified clusters as
(a) In the industrial clusters with CEPI Score above 70, Environmental clearance will not be granted for developmental projects. This condition will apply for 8 months i.e. upto August 2010 during this time CPCB along with respective state pollution control board will finalize time-bound action plan for improving the environmental qualities in these areas.
(b) The developmental projects from industrial area with CEPI score between 60 and 70 will be considered as projects located in critically polluted areas. Environmental Clearance will be accorded to these projects as per MoEF Circular No. J-11013/18/2009-IA II (I) dated 25 August 2009.
(c) Various state government had expressed the difficulties in implementing the above referred Office Memorandum due to inadequate details about the boundaries of polluted areas. So the details of these clusters were clarified by MoEF vide Office Memorandum J-11013/5/2010-IA.II (I).
