Upon completing the review, the consultant shall provide a written analysis of the filing and an opinion of the nature and extent to which it complies with this chapter and adopted rules. The director may adopt rules pursuant to chapter 91 to further delineate the duties of the consultant in undertaking the review and analysis required pursuant to this section.
