Broad details of religious, archaeological and recreational centre, wildlife sanctuaries, national parks, likely to be affected by the project etc. Passage-way review whether suitable and sufficient crossings for people, livestock and wildlife are included in the project design. Of adequacy of planned provision to prevent excessive aquatic weed growth, erosion and seepage, and design of culverts, intakes and protective structures to prevent bank scouring.

  • Netsol Water Solutions, a wastewater treatment company that designs and manufactures ace machines to save the earth and its resources especially water.
  • Though some details may overlap with the information required to establish baseline status of various environmental components, however, the details required at this stage may be quoted later in EIA report.
  • Screening – Screening of project plan for location, area, type of project and its effect on surrounding area.

Extent and nature of forest in the area proposed to be cleared for construction of roads, colonies and other uses of the project. These may include shortage of fuel wood, soil erosion, pollution of surface and ground water and endemic diseases. The consideration of alternatives is of major importance when EIA is taken up at an early stage of project cycle. A Pre-Feasibility Report may, on the basis of analysis of secondary information, establish the adequacy of natural resources for the project and viability of the project if Environmental Clearance were to be accorded. Matrices by themselves do not offer adequate criteria for decision-making; nor do they facilitate later monitoring of impacts. EES is used to evaluate the predicted condition of environmental quality, both ‘with’ and ‘without’ the project.


Local health service units (dispensary, hospital, etc.) are good sources of information. Measures to control contamination of surface and groundwater due to pesticides and fertilizers also need to be drawn up in advance. Possibilities of disease aggravation or new public health problems introduced due to change in population density and distribution also need to be looked into. If necessary, door to door sample surveys can be undertaken to review the quality of information available.

  • EIA ensures that the development plan is ecologically sound and operates within the ecosystem’s capacity for absorption and regeneration.
  • Adoption of a proper mix of various erosion control measures in “very high” priority catchments can reduce the reservoir sedimentation rate to the extent of 60 to 80 percent.
  • Command area and any other area exploited in the process of dam or power plant construction.
  • Each of the above methods is subjective to some extent, and none of these is applicable to every case.

Interpretation of more than 12 overlays at a time is often difficult and this means that only a limited number of impacts can be considered. The network effectively presents a display of factual information, but includes no mechanism for accommodating public input. Each of the above methods is subjective to some extent, and none of these is applicable to every case.

History of EIA in India

At the same time, it is recommended that pH, Electrical Conductivity and Exchangeable Sodium percentage shall be monitored to assess the prevalence, extent of soil salinity conditions. The risk of water logging could be estimated taking into account the groundwater recharge. Backwater effect on the tributaries and drains joining the river on the u/s side of the dam should be computed.

eia methodology

Due to the construction of dam and reservoir, there will be regulation of outflow. The data on annual maximum floods is used to predict T-yr flood through frequency analysis. It is thus necessary not only to consider population projection under normal circumstances but also to forecast immigration to the project area because of enhanced agricultural and other economic activities. Few of them some of which fall short of requisite number of parameters, uses old scientific unit or different units for the same parameter, often reports wrong unit for some and so on. The data so collected provides basis for ranking of these factors and concluding the assessment of health hazards, as low, moderate or high.

Prediction of impacts is a process to forecast the future environmental conditions of the project. Physical characteristics of soil affect sediment transport to river and subsequently to reservoir, limiting its storage capacity and lifetime and robbing downstream waters of sediment. Most of such flood data required for environmental analysis would be available from technical feasibility study.

3.5       Stages in the Prior Environmental Clearance

The following resources are needed for carrying out the proper and effective environmental impact assessment. Has evolved as a management tool and a planning aid that helps in identifying, predicting, assessing impacts on environment from proposed zig zag pattern trading development projects. The notification makes it mandatory for various projects such as mining, thermal power plants, river valley, infrastructure and industries including very small electroplating or foundry units to get environment clearance.

The procurement of the construction materials such as cement, stone, steel, sand etc may also cause significant environmental impacts. The prior environmental clearance granted for a project or activity shall be valid for a period of ten years in the case of River Valley Projects (Item 1 of the Schedule). Environmental impacts both during the construction and the operational phases.

eia methodology

Apprehensions have often been expressed that canal irrigation leads to severe water logging and soil salinity in the command areas of large number of projects. It is, however, a good practice to consider alternatives during project planning, to examine their environmental impacts in deciding which alternative to choose and to report the appraisal of alternatives in EIA. It is a process used to predict the environmental consequences of proposed major development projects, to identify and plan for appropriate measures to reduce adverse impacts. Strategic Environment Assessment refers to systematic analysis of the environmental effects of development policies, plans, programmes and other proposed strategic actions.

EIA/IS-731.1 – Systems Engineering Capability Model – DUPLICATE2

In the context of river valley projects the overall environment of the project area is a matter of concern. Dissemination of all information related to projects from notification to clearance to local communities and the general public. EIA provides a cost effective method to eliminate or minimize the adverse impact of developmental projects. EIA allows decision-makers to assess the impact of development activities on the environment long before the project is executed.

At present the EIA notification limits itself to the stage when environmental clearance is granted. Category A projects require mandatory environmental clearance and thus they do not undergo the screening process. Environment Impact Assessment Notification of 2006 has decentralized the environmental clearance projects by categorizing the developmental projects in two categories, i.e., Category A and Category B . Certain activities permissible under the Coastal Regulation Zone Act, 1991 also require similar clearance.

EIA/IS-731.2 Document1 – Systems Engineering Capability Model Appraisal Method – Intro

The difficulty encountered in the use of this technique is, of course, that impacts have to be transformed and stated in explicit monetary terms and this is not always possible, especially for all environmental and social intangible factors. The overlay method is most useful in screening alternative project sites or routes preliminary to detailed impact analysis. Value function graphs are added up for arriving at the net impact of the project on environmental quality. The simplechecklist is merely a list of parameters and nature of impacts and does not provide guidance on how the environmental parameters are to be measured and interpreted. Know about the possible impacts of any developmental plan x on our environment. Adequate provisions for protection of environment and forest are made in the Constitution of India.

Greater emphasis on ecological modelling, prediction and evaluation methods. Screening – Screening of project plan for location, area, type of project and its effect on surrounding area.

She has conducted environmental focused studios for the planning students in Industrial area Roorkee, Piran Kaliyar Sharif Haridraw, Valley of Flowers, Uttarakhand and North Lakhimpur in Assam. Environmental Impact Assessment is a tool that planners can use to achieve the goal of environmental preservation while still allowing for development. This is often interpreted to be coincident with the point where inundation from the dam failure is within the 100 year floodplain for the affected watercourse. A general description of the areas d/s that could be affected by flood water from a dam failure.
