Environmental Impact Statement

Encyclopedia : E : EN : ENV : Environmental Impact Statement


According to the National Environmental Policy Act (NEPA) whenever the U.S. Federal Government takes a "major Federal action significantly affecting the quality of the human environment" it must first consider the environmental impact in a document called an Environmental Impact Statement (EIS).

An EIS typically has four sections:

The purpose of NEPA is to promote excellence in decision making by federal agencies by making "detailed information concerning significant environmental impacts" available to both agency leaders and the public. (See the Supreme Court decision: Robertson v. Methow Valley Citizens Council, 490 U.S. 332, 349 (1989).)

Not all federal actions require a full EIS. If the action is not likely to cause a significant impact the agency may prepare a smaller, shorter document called an Environmental Assessment (EA). However, EAs are only appropriate if there will be "no signficant impact."

Contrary to a widespread misconception, NEPA does not prohibit the federal government or its licensees/permittees from harming the environment, but merely requires that the prospective impacts be understood and disclosed in advance.

The NEPA Process

The NEPA Process is designed to involve the public and gather the best available information in a single place so that decision makers can be fully informed when they make their choices.

The process has the following steps:

State and International NEPAs

The same general pattern has since been followed by several U.S. state governments that have adopted "little NEPA's," i.e., state laws imposing EIS requirements for particular state actions. Many other countries have also enacted laws requiring environmental impact assessment. For example, the European Community has established a mix of mandatory and discretionary procedures for assessing environmental impacts. [link]

Environmental Impact Assessments

An environmental impact assessment is often confused with an Environmental Impact Statement, but it is not the same thing. An EIA is a creation of the Environmenal Protection Agency used to monitor toxics. The names are unfortunately similar.
