"The National Environmental Policy Act (NEPA) requires environmental impact considerations to be included in project planning along with technical and economic concerns. The thrust of NEPA, as well as The Council on Environmental Quality (CEQ) guidelines and numerous Federal agency procedures, is to ensure that balanced decision making occurs in the interest of public health and welfare. Towards that goal, section 102 of NEPA requires that environmental statements (EIS's) be prepared for "major Federal actions significantly affecting the quality of the human environment." The EIS's purpose is to notify the public and the various decision-making agencies of an action's environmental consequences by defining and evaluating the proposed actions environment effects. It also includes measures to avoid or mitigate the negative impacts. Many useful sources of information have been developed to assist the people responsible for EIS preparation. However, almost no attention has been given to assisting the person who has to review one. It seems to be implied that the same material used for preparation of the document is adequate for its review. Unfortunately, as people who have had to review EIS's know, this is not quite the case. The different perspectives of the preparer and the reviewer require that they approach the EIS from different directions. If the EIS is well prepared, the reviewer's concerns will have been addressed; if the EIS has flaws, the reviewer must be able to ask the right questions to pinpoint the inadequacies. In response to requests from both professional EIS reviewers and the public, the Region V Noise Program has assembled a list of concerns that it feels every EIS should address. This particular document is concerned with airport projects. It is our hope that, in spite of its brevity, it will be a basis from which a competent noise review can be effected."--Preface.
