Section 209.15 - Intervention(a) Persons desiring to intervene in a hearing to be held under section 11(d) of the act shall file a motion setting forth the facts and reasons why they should be permitted to intervene.(b) In passing on a motion to intervene, the following factors, among other things, shall be considered by the administrative law judge: (1) The nature of the movant's interest including the nature and the extent of the property, financial, environmental protection, or other interest of the movant;(2) The effect the order which may be entered in the proceeding may have on the movant's interest;(3) The extent to which the movant's interest will be represented by existing parties or may be protected by other means;(4) The extent to which the movant's participation may reasonably be expected to assist materially in the development of a complete record;(5) The extent to which one movant's participation may reasonably be expected to delay the proceedings.(c) A motion to intervene should be filed before the first prehearing conference, the initiation of correspondence under § 209.20 , or the setting of the time and place for the hearing, whichever occurs earliest. Motions shall be served on all parties. Any opposition to such motion must be filed within 10 days of service.(d) All motions to be made an intervener shall be reviewed by the administrative law judge using the criteria set forth in paragraph (b) of this section and considering any opposition to such motion. The administrative law judge may, in granting such motion, limit a movant's participation to certain issues only.(e) If the administrative law judge grants the motion with respect to any or all issues, he or she shall notify, or direct the hearing clerk to notify, the petitioner and all parties. If the administrative law judge denies the motion he or she shall notify, or direct the hearing clerk to notify, the petitioner and all parties and shall briefly state the reasons why the motion was denied.(f) All motions to be made an intervener shall include the movant's agreement that the movant and any person he or she represents will be subject to examination and cross-examination, and will also include an agreement to make any supporting and relevant records available at the movant's own expense upon the request of the administrative law judge, on his or her own motion or the motion of any party or other intervener. If the intervener fails to comply with any of these requests, the administrative law judge may, in his or her discretion, terminate his or her status as an intervener.
