(ii) Is not covered by a retired unit exemption under § 72.8 of this chapter that is in effect;

(3) A monitoring plan in accordance with subpart HHHH of this part;

(4) A complete certificate of representation under § 96.313 consistent with § 96.382, if no CAIR designated representative has been previously designated for the source that includes the unit; and

(5) A statement, in a format specified by the permitting authority, whether the CAIR designated representative requests that the unit be allocated CAIR NO<sub>X</sub> Ozone Season allowances under § 96.388(b) or § 96.388(c) (subject to the conditions in §§ 96.384(h) and 96.386(g)). If allocation under § 96.388(c) is requested, this statement shall include a statement that the owners and operators of the unit intend to repower the unit before January 1, 2015 and that they will provide, upon request, documentation demonstrating such intent.
