Components of EIA

  Air Environment


  • Determination of impact zone (through a screening model) and developing a monitoring network
  • Monitoring the existing status of ambient air quality within the impacted region (7-10 km from the periphery) of the proposed project site
  • Monitoring the site-specific meteorological data, viz. wind speed and direction, humidity, ambient temperature and environmental lapse rate
  • Estimation of quantities of air emissions including fugitive emissions from the proposed project
  • Identification, quantification and evaluation of other potential emissions (including those of vehicular traffic) within the impact zone and estimation of cumulative of all the emissions/impacts
  • Prediction of changes in the ambient air quality due to point, line and areas source emissions through appropriate air quality models
  • Evaluation of the adequacy of the proposed pollution control devices to meet gaseous emission and ambient air quality standards
  • Description of mitigation measures at source, path ways and receptor 

 

Baseline Monitoring

  Noise Environment & Vibration


  • Monitoring the present status of noise levels within the impact zone, and prediction of future noise levels resulting from the proposed project and related activities including increase in vehicular movement
  • Identification of impacts due to any anticipated rise in noise levels on the surrounding environment
  • Recommendations on mitigation measures for noise pollution

 

Baseline Monitoring

Intensity , Duration and Frequency of noise

  Water Environment


  • Study of existing ground and surface water resources with respect to quantity and quality within the impact zone of the proposed project
  • Prediction of impacts on water resources due to the proposed water use/pumping on account of the project
  • Quantification and characterisation of waste water including toxic organic, from the proposed activity
  • Evaluation of the proposed pollution prevention and wastewater treatment system and suggestions on modification, if required
  • Prediction of impacts of effluent discharge on the quality of the receiving water body using appropriate mathematical/simulation models
  • Assessment of the feasibility of water recycling and reuse and delineation of detailed plan in this regard

Baseline Monitoring

  Biological Environment


  • Survey of flora and fauna clearly delineating season and duration
  • Assessment of flora and fauna present within the impact zone of the project
  • Assessment of potential damage to terrestrial and aquatic flora and fauna due to discharge of effluents and gaseous emissions from the project
  • Assessment of damage to terrestrial flora and fauna due to air pollution, and land use and landscape changes
  • Assessment of damage to aquatic and marine flora and fauna (including commercial fishing) due to physical disturbances and alterations
  • Prediction of biological stresses within the impact zone of the proposed project
  • Delineation of mitigation measures to prevent and / or reduce the damage

 

  Land Environment


  • Studies on soil characteristics, existing land use and topography, landscape and drainage patterns within the impact zone
  • Estimation of impacts of project on land use, landscape, topography, drainage and hydrology
  • Identification of potential utility of treated effluent in land application and subsequent impacts
  • Estimation and Characterisation of solid wastes and delineation of management options for minimisation of waste and environmentally compatible disposal

Baseline Monitoring

  Socio-economic Environment


  • Collection of demographic and related socio-economic data
  • Collection of epidemiological data, including studies on prominent endemic diseases (e.g. fluorosis, malaria, fileria, malnutrition) and morbidity rates among the population within the impact zone
  • Projection of anticipated changes in the socio-economic and health due to the project and related activities including traffic congestion and delineation of measures to minimise adverse impacts
  • Assessment of impact on significant historical, cultural and archaeological sites/places in the area
  • Assessment of economic benefits arising out of the project
  • Assessment of rehabilitation requirements with special emphasis on scheduled areas, if any

Baseline Monitoring

  Risk Assessment


  • Hazard identification taking recourse to hazard indices, inventory analysis, dam break probability, Natural Hazard Probability etc
  • Consequence analysis of failures and accidents resulting in fire, explosion, hazardous releases and dam breaks etc. 
  • Assessment of risk on the basis of the above evaluations
  • Preparation of an onsite and off site (project affected area) Disaster Management Plan

 

  Socio-economic Impact Assessment (SEIA)


Identify and evaluate the potential socio-economic and cultural impacts of a proposed development on the lives and circumstances of people, their families and their communities
