(2) An ordinance adopted before February 8, 1988 by a county or municipality incidental to the financing of a publicly owned disposal area or areas under construction that directs that all or part of the solid waste generated in that county or municipality be directed to the disposal area or areas is an acceptable means of compliance with subsection (1), notwithstanding that the ordinance, in the case of a county, has not been approved by the governor.
