“(A) Subject to subparagraph (B), the Secretary shall not issue a final order under this subsection to any powerplant if it is demonstrated that such powerplant would have been granted an exemption if such prohibition had been established by a final rule pursuant to subsection (span) rather than by order pursuant to this subsection, except that if a temporary exemption would have been granted, such a final order may be issued but may not take effect until such time as the temporary exemption would have terminated.

“(B) In any case in which an order is not issued by reason of subparagraph (A) or in which the effective date of such order is delayed under subparagraph (A), the Secretary shall take such steps as may be necessary to assure the installation involved complies with the same requirements (including provisions of section 8354(a) of this title) as would have been applicable if an exemption had been granted based upon the grounds for which the order is not issued or the effective date of which is delayed.”
