Environmental Impact Assessment (EIA) is used to identify and assess the environmental and social impacts of any proposed major activity (project, plan, programme or policy) prior to its implementation. ENIECO Environment Consultants aim to predict environmental impacts at an early stage in project planning and design, find ways and means to reduce adverse impacts, shape projects to suit the local environment and present the predictions and options to decision-makers.

EIA is anticipatory, participatory and systematic in nature and relies on multidisciplinary input. It is a means to assessing the present state of health of ecosystem where project would be executed and to work out the possible impact it could bring in course of the time. By using EIA both environmental and economic benefits can be achieved, such as reduced cost and time of project implementation and design, avoided treatment/clean-up costs and impacts of laws and regulations.

The objective of EIA is to foresee the potential environmental problems that would arise out of a proposed development and address them in the project's planning and design stage. The EIA process should then allow for the communication of this information to: (a) The project proponent (b) The regulatory agencies and (c) All stakeholders and interest groups.

ENIECO EIA process made up of the following phases: (1) Screening (2) Scoping and consideration of alternatives (3) Baseline data collection (4) Impact prediction (5) Assessment of alternatives, delineation of mitigation measures and environmental impact statement (6) Public hearing (7) Environment Management Plan (8) Decision making (9) Monitoring the clearance conditions.
