ZONING ATLAS FOR SITING OF INDUSTRIES

7.0 RESULTS OF THE ATLAS PROJECT :

The resulting maps of Zoning Atlas include the sensitive zones where no industrial siting should be allowed and the possible alternate sites showing risks due to siting of industries with various types of pollution. The types of zones that will be available and their suitability of various types of polluting industries is given below:

Zone I:
Siting of any type of air and/or water polluting industries should not be allowed. Siting of industries with very low pollution potential (A3 and/or W3) may be considered based on micro-level studies (suitable for A3 W3 only);

Zone II :
Industries having high water pollution potential (W1) and/or any type of air pollution potential (A1/A2/A3) should not be allowed in these zones. Siting of industries with very low air pollution potential (A3) 1 based on micro-Ievel studies, and/or medium or low water pollution potential (W2/W3) may be considered (suitable for A3W2, A3W3 only);

Zone III :
Industries which are water polluting in nature (W1/W2/W3) but not having any type of air pollu- tion potential (A1/A2/A3 -A3 based on local con- ditions) may be considered for siting in this zone (suitable for W1A3,W2A3,W3A3 only);

Zone IV :
Industries having air pollution potential whose im- 1 pact is not likely to exceed 2 km (A2) or industries - having very low pollution potential (A3) but not having any type of water pollution (W1/W2/W3 - W3 based on local conditions) may be considered for siting in this zone; Industries with high air pollution potential. (A3) or high or medium water pollution potential (W2/W1) should not be allowed Zone 11: in this zone; (suitable for A2W3, A3W3 only);

Zone V :
Industries having air pollution potential whose im- pact is not likely to exceed 2 km (A2) or industries havjng very low pollution potential (A3) and/or having medium or low water pollution potential ' (W2/W3) may be considered for siting in this zone; Industries with high air pollution potential (A 1) or ); high water pollution potential (W1) should not be allowed in this zone; (suitable for A2W2, A3W2, A3W3,A2W3 only);

Zone VI:
water Industries having air pollution potential whose impact is not likely to exceed 2 km (A 2) or industries having very low air pollution potential (A3) and/or water polluting in nature (W1/W2/W3) may be considered for siting in this zone; (suitable for A2W1, A2W2, A2W3, A3W1, A3W2, A3W3 only);

Zone VII:
Industries having air pollution potential of A1/A2/A3 but not having any type of water pollution (W1/W2/W3 -W3 may be considered based on local conditions) may be considered for siting in this zone; (suitable for A 1 W3, A2W3, A3W3 only.

Zone VIII :
Industries having air pollution potential of A1/A2/A3 and/or having waste water discharges of only W2/W3 categories may be considered for sitting in this zone; Industries having waste waterof not easily biodegradable and toxical nature should not be allowed in this zone; (suitable for A1W2, A2W2,.A3W2, A 1 W3, A2W3, A3W3 only); and

Zone IX:
All types of air polluting industries (A1/A2/A3) and/or all types of water polluting industries (W1/W2/W3) may be considered for siting in this Zone ~II: zone; (suitable for A 1 W1, A 1 W2, A 1 W3, A2W1 , A2W2, A2W3, A3W1, A3W2, A3W3).

W3 category - industries with wastewater from domestic use/cooling or boiler blow downo (having no temperature variation and metals or other contaminants) or generating no wastewater or industries with complete recycling system/reutilization with 'Zero'discharge
W2 category - industries generating wastewater which is easily biodegradable and non-toxic, industries generating slur- ries and high temperature effluent
W1 category - industries generating wastewater of inorganic nature or organic waste of not easily biodegradable or toxic nature or combination of all and W2, W3 categories
A3 category - industries having emission only from boilers of steam generation capacity less than 2t/hr but not using coal, or noise of FdBA, or using DG sets upto 50 KVA
A2 category - industries with combustion emission from usage of coal 125 t/hr or equivalent,oor generating noise levels between 70-90dBA, or having diesel generator sets 50 KVA
A1 category - industries with emission from combustion of fuels using coal 125 t/hr or equivalent fuel, or industries having process emission emitted through organised let out system (stack) or having fugitive emission or odour nuisance, or in- dustries genE!rating noise levels of 90 dBA and above
S1 category - hazardous waste as defined under rule 3(i), 3(n) and 4 of the Hazardous Waste Management and Handling Rules, 1989 or waste water of not easily biodegradable and toxic nature.
S2 category - inorganic and organic compostable waste and all wastes with leachate potential or wastewater of easily biodegradable and non-toxic nature
S3 category - solid waste of inert nature. or no waste or with recycling arrangements. No discharge of waste water on land.

From the above zones, areas for deve!opment of industrial estates may be identified in consultation with other Depar1ments of the Government, such as the Industries Depar1ment, the Town & Country Planning Depar1ment, the Electricity Depar1ment, PWD, the Industrial. Development & Investment. - Corporation etc, With the Involvement of these, agencies, the economic considerations, such as water supply, electricity network, industrial development needs etc. will be taken care 'of. . Detailed micro-Ievel studies (region-based en- based on studies in 1: 250,000 scale and vironmental impact assessment) in an area of 25- km around each of the identjfied sites should be While selecting such areas, preference may be given to wastelands.

The 'high risk' zones showr, in the groundwater sensitivity map are very sensitive to groundwater , polluting activities and hence, disposal of effluents or solid/hazardous waste on land should not be allowed, The 'medium' risk areas are suitable for controlled and limited discharges of only easily biodegradable and non-toxic effluents. The 'low risk areas provide scope for disposing hazardous wastes, based on micro-level studies.
