An applicant may request an adjudicative proceeding in the following circumstances:

(1) Where the applicant has received an informal opinion pursuant to RCW 43.72.310 and within thirty days of the applicant's receipt of the opinion, the applicant requests an adjudicatory proceeding to determine whether the proposed conduct should be authorized pursuant to RCW 43.72.310 (2)(a) because it is likely to achieve the policy goals of chapter 43.72 RCW and a more competitive alternative is impractical;

(2) If the attorney general concludes in its informal opinion that the conduct proposed is not authorized by chapter 43.72 RCW, the requesting applicant shall have thirty days from the date of receipt of the informal opinion from the commission to file a written petition with the commission requesting approval of conduct that could tend to lessen competition in the relevant market pursuant to RCW 43.72.310(3). The petition shall constitute an application for an adjudicatory proceeding under RCW 34.05.413; or

(3) Pursuant to RCW 43.72.310(3) an applicant may file a written petition with the commission requesting approval of conduct that could tend to lessen competition in the relevant market regardless of whether it has previously sought an informal opinion. The petition shall constitute an application for an adjudicatory proceeding under RCW 34.05.413.
