Limitation and Recommendations
  • This Atlas provides only the macro-level aspects and for micro-level planning detailed studies are to be carried out. The information provided by the set of maps are primarily to be used for a reconnaissance of the planning area.
  • The Zoning Atlas considers only the environmental aspects.
  • The identified zones for industrial siting are based on studies in 1: 2,50,000 scale and based on available data. Hence, the conclusions drawn from this Atlas only provide guidelines for taking decisions on industrial siting and should not be considered as consent to establish Industries. Micro-level detailed studies are to be carried out and in case of large scale industries environmental impact assessment (EIA) is to be carried out before taking decision on siting an industry.
  • The conclusions in the present Atlas are based on rapid EIA and hence in the identified industrial zones, even if the risks due to pollution are high/medium/low, there should not be any discharge of effluents/emissions/waste without treatment and meating the required environmental standards.
  • The industries adopting clean teehnology for manufacturing process may not have the pollution generation potential same as those without the clean technology process and hence may be considered sultable even for 'medium' and 'high' risk zones.
  • The Atlas and the recommendations have been developed based on the current scenario in the district. The Atlas needs modification/updating as and when the scenario of the land uses or the environmental quality or any theme (data/information) relating to air/water pollution sensitivity changes.
  • Since, local features in too small an area to be mapped are eventually excluded, the judgement given might be principally showing a bias towards the better (less sensitive) side. Specific local conditions are eventually liable to increase the actual sensitivity and hence lower the suitability. This necessitates detailed in-depth investigations of sites pre-selected based on the maps for further consideration (micro scale analysis). Large-scale maps of the site-specific local features are needed for final decision-making (industrial zoning).
  • For individual industries eventually not fitting into the general industrial classification scheme, specific site evaluation criteria need to be developed.
  • Specific and unique local features might necessitate change in the evaluation procedures e.g. by changing critical thresholds or overlay procedures.
  • In order to mini mise obvious misjudgements by insufficient data as well as inadequate model assumptions, the model has to be validated by ocular field inspections of the results obtained. It is strongly recommended to the user that prior to any further investigations pre-identified or selected areas should be subjected to an in-depth ocular survey.
