In order to preclude the delays or denials described in subdivision (c) of Section 8708, the department shall establish a statewide exchange system that interjurisdictionally matches waiting children and approved adoptive families. The department may create a new statewide exchange system, modify an existing statewide exchange system, such as the photo-listing service described in Section 8707, or designate an existing exchange system, such as the Adoption Exchange Enhancement Program, as the statewide exchange system for purposes of this section.
