Haw. Code R. § 20-1.1-18
The board shall, within thirty days following the filing of a petition, either deny the petition in writing or initiate public rulemaking procedures. No public hearing, oral argument or other form of proceeding will be held directly on any petition, but if the board determines that the petition discloses sufficient reasons in support of the relief requested to justify the institution of public rulemaking proceedings, the procedures to be followed will be as set forth in section 91-3, HRS, and this subchapter. Where the board determines that the petition does not disclose sufficient reasons to justify the institution of public rulemaking procedures, or where the petition does not concern a rule, the board shall deny the petition and the petitioner will be so notified together with the grounds for the denial. This section shall not operate to prevent the board, on its own motion, from acting on any matter disclosed in any petition.
