Environmental Planning


Tripura State Pollution Control Board, in collaboration with Central Pollution Control Board (CPCB) and German Technical Co-operation (GTZ) has successfully completed the Zoning  Atlas for Siting of Industries for the entire State under the World Bank funded Environment Management Capacity Building Project. As a follow up of the Zoning Atlas project,

The Zoning Atlas for siting of industries zones and classifies the environment in a district and presents the pollution receiving potential of various sites/zones in the district and the possible alternate sites for industries through easy-to-read maps.
The specific objectives of preparing the Zoning Atlas for siting of industries are:

  • to zone and classify the environment in a district;
  • to identify locations for siting of industries; and
  • to identify industries suitable to the identified sites.

The Zoning Atlas considers only the environmental aspects. For siting of industries, both the economic factors, such as availability of raw materials, market for finished product, water supply, electricity, labour , availability etc., and the environmental factors are to be considered. Consideration of economic factors : maximises profits over a short period but consideration of environmental factors minimises liabilities over a longer period. Assuming that the industries are the best in identifying the sites best suitable from economic considerations, the Zoning Atlas addresses to the environmental considerations only. The industries may subsequently evaluate the site suitability from both the considerations.

Zoning Atalas in addition to streamlining the decision making process has several benefits,some of which are briefed below.

  • provides a ready-reckoner for best suitable site and relevant environmental information;
  • makes decision-making process simpler, faster, realistic, transparent and reliable;
  • provides a basis for incorporating environmental aspects into physical (land use) planning process;
  • helps in planning cost-effective pollution control measures and programmes;
  • helps an entrepreneur in readily finding out the location best suited to site an industry thereby saving time, efforts, investment and risk instead of heading for an unknown site, conducting environmental impact assessment and awaiting clearance by the regulatory authorities;
  • helps develop infrastructure facilities, such as roads, water supply, electricity, etc. and provide common waste treatment and disposal facilities;
  • helps check additional pollution in the areas already over-stressed with pollution;
  • ensures that pollution potential of an industry is made compatible with the local conditions of the site;
  • ensures that an industry, with high pollution potential desiring to locate in a high risk area, will have to adopt clean technologies for manufacturing process so as to prevent generation of wastes/pollution thereby making it compatible with the receiving environment;
  • helps in' increasing awareness of the public on type of industries and nature of pollution anticipated in their neighbourhood well in advance; and
  • helps achieve sustainable development.


Step I : Preparation of the base map of the district; .I
Step II Preparation of themes which show the physical features of the district (land use map. drainage, 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: Preperation of theme maps pertaining to air pollution sensitivity ,surface water pollution sensitivity and groundwater pollution sensitivity;

StepV: Preperation 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 if the sites to air and water pollution and the

risks associated with industrial siting; and

b)possible solid waste disposal sites based on the sensitivity to groundwater pollution

Step VI : Listing of the categories of industry suitable
to various sites identified and recommending guidelines for siting of industries and the site clearance procedures
