ANNOTATION

By referring to § 24-4-105 in subsection (3) of this section, the general assembly mandated an administrative hearing for parties challenging general permits issued by the division before seeking judicial review. The use of the word "may" in subsection (3) created an avenue by which a party could seek an administrative appeal by requesting a hearing under § 24-4-105, but the statute's permissive language did not eliminate the party's obligation to exhaust that administrative remedy before filing its complaint for judicial review in the district court.
