(ii) A complete permit application is submitted covering each unit governed by such plan.

If the compliance option includes a plan described in subsection (2)(a) of this section, the designated representative for each source governed by the plan shall sign and certify the notification.

(b) The notification under (a) of this subsection shall specify the calendar year for which the termination will take effect.

(c) Upon submission of a notification meeting the requirements of (a) and (b) of this subsection, the termination becomes binding on the owners and operators and the designated representative of any unit governed by the acid rain compliance option to be terminated.
