The board may intervene in a proceeding if a petition is filed with the board for referral of a question of water policy involved in the proceeding.
A petition for intervention must identify the proceeding in which it is made and state the grounds for referral in a general manner with sufficient detail to inform interested parties of the nature of the questions proposed to be presented to the board and the public importance of the questions.
(a) A petition for intervention may be made by:
(1) the applicant in the proceeding;
(2) a party to the proceeding;
(3) the governor;
(4) the agency;
(5) the commissioner or director of a division in the Department of Natural Resources;
(6) the head of another state department or agency;
(7) a bureau or division of the federal government with a concern in the proceeding;
(8) an organization or group of persons with appropriate purpose related to the proceedings; or
(9) a person the board considers representative of a substantial segment of the state or peculiarly able to present evidence bearing on the public interest.
(b) The petition must be:
(1) signed and verified by the petitioner or an officer of the petitioner; or
(2) signed by the petitioner's attorney.
The petition must be filed in duplicate, one copy with the board, the other with the agency.
