If the plan proposes designation to disposal facilities, the designation plan shall also evaluate:
(1) Whether the disposal facility is part of an integrated waste management system involving a processing facility and the designation is necessary for the financial support of the processing facility;
(2) Whether the designation will better serve to protect public health and safety;
(3) The impacts on other disposal facilities inside and outside the area;
(4) Whether the designation is necessary to promote regional waste management programs and cooperation; and
(5) The extent to which the design and operation of the disposal facility protects the environment including whether it is permitted under current law.
