If the Commission determines a contested case is appropriate, the petition for a contested case shall be filed within 20 days after the Commission makes its determination. A determination that a person may not commence a contested case is a final agency decision and is subject to judicial review under Article 4 of Chapter 150B of the General Statutes. If, on judicial review, the court determines that the Commission erred in determining that a contested case would not be appropriate, the court shall remand the matter for a contested case hearing under G.S. 150B-23 and final decision on the permit pursuant to G.S. 113A-122. Decisions in such cases shall be rendered pursuant to those rules, regulations, and other applicable laws in effect at the time of the commencement of the contested case.
