has sufficient inherent design characteristics to permit the addition of equipment (including all necessary pollution devices) necessary to render such electric powerplant capable of using coal or another alternate fuel as its primary energy source; and

is not physically, structurally, or technologically precluded from using coal or another alternate fuel as its primary energy source.

This section shall apply only to base load powerplants, and shall not apply to peakload powerplants or intermediate load powerplants.

For the purposes of this section, hours of electrical generation pursuant to emergency situations, as defined by the Secretary and reported to the Secretary, shall not be included in a determination of whether a powerplant is being operated as a base load powerplant.

In order to meet the requirement of subsection (a), the owner or operator of any new electric powerplant to be operated as a base load powerplant proposing to use natural gas or petroleum as its primary energy source shall certify to the Secretary prior to construction, or prior to operation as a base load powerplant in the case of a new electric powerplant operated as a peakload powerplant or intermediate load powerplant, that such powerplant has capability to use coal or another alternate fuel, within the meaning of subsection (b). Such certification shall be effective to establish compliance with the requirement of subsection (a) as of the date it is filed with the Secretary. Within 15 days after receipt of a certification submitted pursuant to this paragraph, the Secretary shall publish in the Federal Register a notice reciting that the certification has been filed.

The Secretary, within 60 days after the filing of a certification under paragraph (1), may require the owner or operator of such powerplant to provide such supporting documents as may be necessary to verify the certification.
