Title 42 › Chapter CHAPTER 92— - POWERPLANT AND INDUSTRIAL FUEL USE › Subchapter SUBCHAPTER II— - NEW FACILITIES › Part Part B— - Exemptions › § 8321
The Secretary must let a power plant use natural gas or petroleum if the plant owner files a petition and proves that, after honest and careful efforts, one of these is true: coal or another alternate fuel of the needed quality probably will not be available during the exemption period at a cost (including transport and use) that, by the Secretary’s cost rule and best practical estimates, is not much higher than the fuel the plant would otherwise use; site limits prevent locating or running the plant on coal or another alternate fuel; or following the part A restrictions would force the plant to break other environmental rules. The Secretary can also grant an exemption if the owner shows they will comply by the end of the exemption by switching to a synthetic fuel made from coal or another alternate fuel, and they cannot make that switch sooner. Exemptions generally cannot last more than 5 years, but ones based on the first reason or the synthetic-fuel plan may be extended up to 10 years. Time before the plant starts operating does not count toward those limits.
