§ 164.31 Intervention.

(a) Motion. Any person may file a motion for leave to intervene in a hearing conducted under this subpart. A motion must set forth the grounds for the proposed intervention, the position and interest of the movant in the proceeding and the documents proposed to be filed pursuant to either § 164.22 or § 164.24.

(b) When filed. A motion for leave to intervene in a hearing must ordinarily be filed prior to the commencement of the first prehearing conference. Any motion filed after that time must contain, in addition to the information set forth in paragraph (a) of this section, a statement of good cause for the failure to file the motion prior to the commencement of the first prehearing conference, and shall be granted only upon a finding (1) that extraordinary circumstances justify the granting of the motion, or (2) that the intervenor shall be bound by agreements, arrangements, and other matters previously made in the proceeding.
