Environmental Impact Assessment (EIA)


Under United States environmental law an Environmental Assessment (EA) is compiled to determine the need for an Environmental Impact Statement (EIS), and originated in the National Environmental Policy Act (NEPA), enacted in 1970.


An environmental impact assessment (EIA) is an assessment of the possible impact—positive or negative—that a proposed project may have on the natural environment. The purpose of the assessment is to ensure that decision makers consider the ensuing environmental impacts to decide whether to proceed with the project. The International Association for Impact Assessment (IAIA) defines an environmental impact assessment as "the process of identifying, predicting, evaluating and mitigating the biophysical, social, and other relevant effects of development proposals prior to major decisions being taken and commitments made.”  After an EIA, the precautionary and polluter pays principles may be applied to prevent, limit, or require strict liability or insurance coverage to a project, based on its likely harms. Environmental impact assessments are sometimes controversial.


Environmental impact assessment is used to integrate environmental management with the approvals process for proposals. Environmental impact assessment is intended to:

  • ensure that proponents assume primary responsibility for protection of any environmental values that may be affected by their proposals;

  • address environmental management for the expected life of proposals;

  • contribute to statutory decisions on whether a proposal should proceed, and if so, decide what environmental management and monitoring conditions should apply; and

  • where legislation allows, incorporate community and stakeholder views in assessment and decision-making processes.


EIA is an important tool for incorporating environmental concerns at the project level.  EIA should be carried out as early as the project planning stage as part of feasibility thus it can assure that the project will be environmentally feasible


EIA requires an in-depth analysis because of the potential significance of environmental impacts from the project. EIAs demand: (i) comprehensive analysis of the potential impacts; (ii) works to be carried out to formulate practical mitigation measures;  (iii) in-depth economic valuation of impact to screen and evaluate the best alternative; and (vi) in-depth analysis to prepare an adequate environmental management plan.


With MCGI on the project, decisions are made with an understanding of scientific issues and the legal implications of every technical decision.


We look forward to the privilege of serving your project needs.
