(e) The director shall deny the demonstration period if the designated representative cannot demonstrate that the unit met the requirements of paragraph (A)(2) of this rule. In such cases, the director shall require that the owner or operator operate the unit in compliance with the applicable emission limitation in rule 3745-103-57, 3745-103-58, or 3745-103-59 of the Administrative Code for the period preceding the submission of the application for an alternative emission limitation demonstration period, including the operating period, if such periods are after the date on which the unit is subject to the standard limit under rule 3745-103-57, 3745-103-58, or 3745-103-59 of the Administrative Code.
(2) Alternative emission limitation.
(a) If the director and the USEPA determine that the requirements in this rule are met, the director and the USEPA shall approve an alternative emission limitation and the director shall issue or revise an acid rain permit to apply the approved limitation, in accordance with rule 3745-103-13 of the Administrative Code. The permit shall authorize the unit to emit at a rate not greater than the approved alternative emission limitation, beginning on the effective date the director revises the applicable acid rain permit to approve the alternative emission limitation.
(b) If Ohio EPA or the USEPA disapproves an alternative emission limitation under paragraph (A)(2) of this rule, the owner or operator shall operate the affected unit in compliance with the applicable emission limitation in rule 3745-103-57, 3745-103-58, or 3745-103-59 of the Administrative Code (unless the unit is participating in an approved averaging plan under rule 3745-103-63 of the Administrative Code) beginning on the date the director revises an acid rain permit to disapprove an alternative emission limitation.
(3) Alternative emission limitation renewal.
(a) If, upon review of a petition to renew an approved alternative emission limitation, the director determines that no changes have been made to the control technology, the source's operation, the operating conditions on which the alternative emission limitation was based, or the actual NOx emission rate, the alternative emission limitation shall be renewed.
(b) If the director determines that changes have been made to either the control technology, the source's operation, the fuel quality, or the operating conditions on which the alternative emission limitation was based, the designated representative shall submit, in order to renew the alternative emission limitation or to obtain a new alternative emission limitation, a petition for an alternative emission limitation demonstration period that meets the requirements of paragraph (D) of this rule using a new demonstration period, and the director shall approve or deny the petition in accordance with paragraph (F) of this rule.
