The impact of an activity is a deviation (a change) from the baseline situation that is caused by the activity.

The baseline situation is the existing environmental situation or condition in the absence of the activity.

EIA was first developed in the US as a result of the National Environmental Policy Act of 1969(NEPA), for considering possible impacts prior to a decision being taken on whether or not a proposal should be given approval to proceed.

THE PROCESS INCLUDES FOLLOWING STEPS:

1. Screening2. Scoping3. Impact analysis4. Impact mitigation5. Reporting6. Review7. Decision making8. Monitoring

1. SCREENING

The screening process determines whether a particular project requires preparation of an EIA or not.

2. SCOPING

Scoping is a stage, usually involving the public and other interested parties, that identifies the key environmental issues that should be addressed in an EIA.

3. IMPACT ANALYSIS

The type, extent, duration, timing, severity and significance of the impact is analyzed.

4. IMPACT MITIGATION

Ensuring that residual impacts are within acceptable levels and to enhance environmental and social benefits.

It is the implementation of measures designed to reduce the undesirable effects of a proposed action on the environment

5. REPORTING

Report of EIA is prepared and submitted to the concerned authority.

CONTENTS OF REPORT

6. REVIEW

In this step, the report is studied thoroughly for any deficiencies and corrections are made. Public participation is the important part of this step.

7. DECISION MAKING

Involves deciding whether the project is acceptable or not. The terms and conditions are finalized in this step.

8. MONITORING

Involves ensuring the implementation of

conditions attached to a decision,

verification of impacts are as predicted or

permitted, confirming the mitigation

measures are working as expected, taking

action to manage any unforeseen changes.

WHERE IS EIA REQUIRED?

For schedule 1 projects, carrying out EIA is MUST.

For schedule 2 projects, EIA must be carried out if the development is likely to have a significant impact on the environment by virtue of its nature, size or location.

SCHEDULE 1 PROJECTS

Major power plants Chemical works Waste disposal incineration Major Roads Schemes
