Environmental Impact Assessment (EIA) is a process of identification, prediction, evaluation and mitigation of impacts, on environment including air, water, land,socioeconomic, marine environment and other relevant aspects due to proposed development, at early stage of project planning.

It is inevitable that the proposed development would cause some environmental impact, the intensity of which would vary depending on several factors such as quality and quantity of pollutants, the assimilative capacity of receiving environment and degree of ecological sensitivity of that environment over the natural background.Hence, EIA studies would predict impacts that might happen due to proposed development altering the natural background of physical, chemical, biological, geological, social, economic, and aesthetic dimensions.These studies integrate the environmental concerns of proposed developmental activities into the process of decision making.

Hence, the EIA study is a tool for sustainable development and also a basic requirement for any project to provide the guidelines right from site selection-feasibility to construction and operational phase.

Thus EIA has emerged as one of the successful policy innovations of the 20th Century in the process of ensuring sustainable development. Today, EIA is formalized as a regulatory tool for effective integration of environmental concerns in theeconomic development process. The EIA process is made mandatory and also given a legislative status through a Notification issued by the Ministry ofEnvironment and Forests (MoEF) in January 1994. The Notification, however, coveredonly a few selected industrial developmental activities. There are subsequentamendments and the Notification issued on September 14, 2006, supersedes all the earlierNotifications, and has brought out structural changes in the clearance mechanism.

The basic tenets of this EIA Notification could be summarized into the following:

• Pollution potential as the basis for prior environmental clearance instead of investment criteria.

• Decentralization of clearing powers to the State/Union Territory (UT) level Authorities for certain developmental activities to make the prior environmental clearance process quicker, transparent and effective.

It is essential to define the baseline environmental quality against which the monitoring results can be compared in future to maintain a healthy environment.

Objectives of EIA

  • • To ensure environmental considerations which are addressed and incorporated into the development decision-making process.
  • • To anticipate and avoid or minimize the adverse significant biophysical, social and other relevant impacts due to proposed development.
  • • To protect environment and ecological balance that maintains the natural system.
  • • To promote sustainable development and optimize opportunities.

An EIA should meet at least three core value shown as below:

  • Integrity: The EIA process should be with fair objective, unbiased and balanced.
  • Utility: The EIA process should provide balanced and credible information for decision making.
  • Sustainability: The EIA process should result in environmental safeguards.

The EIA study delivers the following aspects:

  • • Feasibility of site
  • • Probable impacts due to proposed developmental activities.
  • • Baseline data creation based on available information and fresh data collection.
  • • Mitigation Measures.
  • Environment Management Plan (EMP).

Pollution Control Strategies

Pollution control strategies can be broadly categorized in to preventive and reactive. The reactive strategy refers to the steps that may be applied once the wastes are generated or contamination of the receiving environment takes place. The control technology is to minimize the impact due to the process rejects/wastes which varies with quantity and characteristics. This preventive approach refers to a hierarchy that involves i) prevention & reduction; ii) recycling and re-use; iii) treatment; and iv) disposal


The EIA study basically consists two major segments:

  • • Terrestrial EIA
  • • Marine EIA

Terrestrial EIA:
Any proposed development on land is expected to have adverse effect on land environment in terms of land use pattern, vegetation, air, water ( surface water and ground water), soil, noise, meteorological, socioeconomic, and many other related aspects. It is a requirement as per the guideline of MoEFCC to conduct an EIA study prior to project begins. The study of terrestrial EIA is conducted in radius of 10 km from proposed project site. Feasibility study of site is an essential requisite in the process of EIA study.
All above parameters would be studied and if any ecological sensitive aspect like National Park or bird sanctuary etc is identified in the radius of 10 km, the same has to be described well in EIA report. The probable adverse impact due to proposed activities on surrounding terrestrial environment should be identified and degree of impact should be evaluated. Mitigation measures and EMP should be discussed well in EIA report. Recommendation of project to concerned department (MoEFCC and CPCB or State Level Authority) should be based on negligible or temporary or reversible impact on terrestrial environment.

Marine EIA
Developments at the coast or in sea will have an impact on marine environment. The marine environment is complex. New developments can influence coastal processes, coastal erosion, marine sediments, marine ecology, marine biodiversity, and marine water quality. They can alter the marine ecosystem, coastal biodiversity and sea users interact. Some developments, like a few industrial complexes or CETPs,though they away from the shore line, discharge their treated effluents into sea through pipeline and hence require marine EIA studies for suggesting impact if any, mitigation and EMP. The developments like jetties, ports, harbors, petroleum complexes, refineries, desalination plants, thermal power plants, etc are major projects concerned with marine EIA studies.
The marine EIA study includes site selection, baseline environmental criteria, Impact Prediction due to proposed activities, Potential EnvironmentalImpact Assessment, Mitigation, and EMP.

Physical processes
Physical parameters: Tides, Currents, Circulation pattern, thermal dispersal area,dilution, assimilation capacity etc . Water quality
Parameters: Salinity, pH, DO, BOD3, COD,chloride, sulphide, sulphate, floride, nitrate, nitrite, ammonia, Total Nitrogen, PHc, Phenol etc. Sediment Quality
Parameters: Sub tidal and inter tidal sediments are collected and analyzed for selected mantels like Chromium, Iron, Cobalt, Nickel, Copper, Zinc, Lead, Cadmium, Mercury, Organic Carbon, Phosphorus and PHc etc. Flora and Fauna
Parameters: Phytoplankton pigments, population and species diversity, Zooplankton biomass, population and group diversity, macrobenthic biomass, population and group diversity, fishery, breeding grounds, corals, oysters, turtles,sandunes, sea grass, active mud flats, mangroves, sea birds nesting grounds etc. ASSESSMENT
The results of above studies would be useful to assess the potential environmental impacts, during operational phase. MITIGATION
Suitable mitigation measures are suggested to minimize the adverse impact, if identified and predicted due to proposed activities. ENVIRONMENT MANAGEMENT PLAN
To maintain a healthy environment, it is essential to suggest an EMP under which periodic monitoring has to be carried out for evaluating adverse impact, if any, taking place due that activities. RECOMMENDATION
Recommendation of project to concerned department (MoEFCC and CPCB or State Level Authorities) is made based on negligible or temporary or reversible impact on marine environment.
