(1) Proposals which are not so closely related to each other as to be, in effect, a single action, and which are related to a large existing or planned network of highways, streets, etc., may be separated, and the present proposal may be treated as the total proposal, or only some of the future elements of a proposed action may be selected for present consideration in a threshold determination or EIS. These categorizations shall be logical with relation to the design of the total system or network, and shall not be made merely to divide a larger system into exempted fragments. These categorizations shall (a) connect logical termini (population centers, major traffic generators, major crossroads, etc.); (b) possess a reasonable degree of independent utility; and (c) promote a meaningful consideration of alternatives by avoiding the necessity of considering numerous combinations of different alternatives.

(2) Functionally related actions which are not categorically exempted by the provisions of WAC 197-11-800, and whose impacts are more significant and more readily analyzable on a "program" than on an "individual action" basis, may be analyzed, for purposes of threshold determinations and EIS preparation, as a total program.
