(vii) Commencement of commercial operation of the repowering technology.

(e) For a plan under subsection (2)(b) of this section:

(i) Identification of the new unit. A new unit shall not be included in more than one repowering extension plan.

(ii) Certification that the new unit will replace the existing unit.

(iii) Certification that the new unit has the same designated representative as the existing unit.

(iv) Certification that the existing unit will be permanently retired from service on or before the date the new unit commences commercial operation.

(f) The special provisions of subsection (7) of this section.

(5) The permitting authority's action on repowering extension plan.

(a) The permitting authority will not approve a repowering extension plan until the administrator makes a conditional determination that the technology is a qualified repowering technology, unless the permitting authority approves such plan subject to the conditional determination of the administrator.

(b) Permit issuance.

(i) Upon a conditional determination by the administrator that the technology to be used in the repowering extension plan is a qualified repowering technology and a determination by the permitting authority that such plan meets the requirements of this section, the permitting authority will issue the acid rain portion of the operating permit including:

(A) The approved repowering extension plan; and

(B) A schedule of compliance with enforceable milestones for construction, installation, and commencement of operation of the repowering technology and other requirements necessary to ensure that emission reduction requirements under this section will be met.

(ii) Except as otherwise provided in subsection (6) of this section, the repowering extension shall be in effect starting January 1, 2000, and ending on the day before the date (specified in the acid rain permit) on which the existing unit will be removed from operation to install the qualifying repowering technology or will be permanently removed from service for replacement by a new unit with such technology; provided that the repowering extension shall end no later than December 31, 2003.

(iii) The portion of the operating permit specifying the repowering extension and other requirements under (b)(i) of this subsection shall be subject to the administrator's final determination, under 40 C.F.R. 72.44 (d)(4), that the technology to be used in the repowering extension plan is a qualifying repowering technology.

(c) Allowance allocation. Allowances will be allocated in accordance with 40 C.F.R. 72.44 (f)(3) and (g).

(6) Failed repowering projects.

(a)(i) If, at any time before the end of the repowering extension under subsection (5)(b)(ii) of this section, the designated representative of a unit governed by an approved repowering extension plan submits the notification under WAC 173-406-802(4) that the owners and operators have decided to terminate efforts to properly design, construct, and test the repowering technology specified in the plan before completion of construction or start up testing, the designated representative may submit to the permitting authority a proposed permit modification demonstrating that such efforts were in good faith. If such demonstration is to the satisfaction of the administrator, the unit shall not be deemed in violation of the act because of such a termination and the permitting authority will revise the operating permit in accordance with (a)(ii) of this subsection.

(ii) Regardless of whether notification under (a)(i) of this subsection is given, the repowering extension will end beginning on the earlier of the date of such notification or the date by which the designated representative was required to give such notification under WAC 173-406-802(4).

(b) The designated representative of a unit governed by an approved repowering extension plan may submit to the permitting authority a proposed permit modification demonstrating that the repowering technology specified in the plan was properly constructed and tested on such unit but was unable to achieve the emissions reduction limitations specified in the plan and that it is economically or technologically infeasible to modify the technology to achieve such limits. In order to be properly constructed and tested, the repowering technology shall be constructed at least to the extent necessary for direct testing of the multiple combustion emissions (including sulfur dioxide and nitrogen oxides) from such unit while operating the technology at nameplate capacity. If such demonstration is to the satisfaction of the administrator.

(i) The unit shall not be deemed in violation of the act because of such failure to achieve the emissions reduction limitations;

(ii) The permitting authority will revise the acid rain portion of the operating permit in accordance with the following:

(A) The existing unit may be retrofitted or repowered with another clean coal or other available control technology; and

(B) The repowering extension will continue in effect until the earlier of the date the existing unit commences commercial operation with such control technology or December 31, 2003.

(7) Special provisions.

(a) Emissions limitations.

(i) Sulfur dioxide. Allowances allocated during the repowering extension under subsections (5)(c) and (6) of this section to a unit governed by an approved repowering extension plan shall not be transferred to any allowance tracking system account other than the unit accounts of other units at the same source as that unit.

(ii) Nitrogen oxides. Any existing unit governed by an approved repowering extension plan shall be subject to the acid rain emissions limitations for nitrogen oxides in accordance with section 407 of the act and regulations implementing section 407 of the act beginning on the date that the unit is removed from operation to install the repowering technology or is permanently removed from service.
