ATLAS FOR SITING OF INDUSTRIES |
The work is initiated in selected Districts in the first instance. Priority of the Districts is fixed based on the following:
The approach involves carrying out of rapid study in 1:250,000 scale (1 cm= 2.5 km) and subsequently carrying out of detailed micro-level studies in 1:50,000 scale. The zoning for siting of industries is made through overlaying of thematic maps and by the method of elimination of areas unsuitable for industrial activity due to different environmental conditions of sensitivity. The approach involves identification of the characteristics of the District, mapping of the sensitive zones that are unsuitable for siting of industries owing to legal restrictions, physical constraints, social consideration etc. thereby assessing the pollution receiving potential of the District in terms of air/water (surface/ground) pollution and identification of possible alternate sites suiting to different types of pollution potentials of the industries. The master copies of all maps needed for working purposes will be stored on transparency films in 1:250,000 scale. However, for final presentation and dissemination of information for implementation or decision-making purposes, the maps will be published in A3 size. The procedure for preparing Zoning Atlas for a District is broadly categorised into six steps, as given below:

| Step I : | Preparation of the base map of the district; | |
| Step II : | Preparation of themes which show the physical features of the district (land use map, draniage, physiography, land capability etc.) | |
| Step III : | Identification of areas showing 'Sensitive Zones' which are unsuitable for industrial siting from environmental considerations/guidelines, legal restrictions and physical constraints | |
| Step IV : | Preparation of theme maps pertaining to air pollution sensitivity, surface water pollution sensitivity and ground water pollution sensitivity. | |
| Step V : | Preparation of 'Pollution sensitivity' maps based on overlay of theme maps and identification of: | |
| (a) possible alternate sites for location of industries based on the sensitivity of the sites to air and water pollution and the risks associated with industrial siting; and | ||
