1.    An act of God; or
2.    A power outage or a massive discharge of any pollutant that could not reasonably have been anticipated by the owner or operator of the plant; or
(ii)    As long as the sewage treatment plant:
1.    A.    Is in compliance with a compliance schedule contained in an order issued by the Department; and
B.    Meets all interim effluent limitations established by the Department; or
2.    A.    Has recently upgraded to meet more stringent standards and is operating under a start-up program and schedule approved by the Department;
B.    Is implementing operational modifications to accomplish biological nutrient removal under a program and schedule approved by the Department; or
C.    Is accomplishing major maintenance or facility repair under a program and schedule approved by the Department; or
(iii)    If compliance with the effluent limitations set forth in this section is prevented by a judicial or administrative action initiated by a person other than an agency responsible for regulating the sewage treatment plant or the owner or operator of the sewage treatment plant.
(3)    For purposes of the waiver allowed in paragraph (2)(ii) of this subsection, the Department may not issue any waiver if the compliance schedule in effect as of October 1, 1992 or any subsequent compliance schedule is modified by the Department, except that a waiver may be allowed if:
