(1) The primary purpose of an environmental impact statement is to ensure that SEPA's policies are an integral part of the ongoing programs and actions of state and local government.

(2) An EIS shall provide impartial discussion of significant environmental impacts and shall inform decision makers and the public of reasonable alternatives, including mitigation measures, that would avoid or minimize adverse impacts or enhance environmental quality.

(3) Environmental impact statements shall be concise, clear, and to the point, and shall be supported by the necessary environmental analysis. The purpose of an EIS is best served by short documents containing summaries of, or reference to, technical data and by avoiding excessively detailed and overly technical information. The volume of an EIS does not bear on its adequacy. Larger documents may even hinder the decision making process.

(4) The EIS process enables government agencies and interested citizens to review and comment on proposed government actions, including government approval of private projects and their environmental effects. This process is intended to assist the agencies and applicants to improve their plans and decisions, and to encourage the resolution of potential concerns or problems prior to issuing a final statement. An environmental impact statement is more than a disclosure document. It shall be used by agency officials in conjunction with other relevant materials and considerations to plan actions and make decisions.
