This part provides rules for:

(1) Notice and public availability of environmental documents, especially environmental impact statements;

(2) Consultation and comment by agencies and members of the public on environmental documents;

(3) Public hearings and meetings; and

(4) Lead agency response to comments and preparation of final environmental impact statements. Review, comment, and responsiveness to comments on a draft EIS are the focal point of the act's commenting process because the DEIS is developed as a result of scoping and serves as the basis for the final statement.
