Title 42 › CHAPTER 92 — POWERPLANT AND INDUSTRIAL FUEL USE › SUBCHAPTER III — EXISTING FACILITIES › Part B — Exemptions › § 8351
Powerplants can get a temporary OK to keep using natural gas or petroleum if they file a petition and the Secretary reviews it and the public’s comments. Exemptions must be granted when the plant proves certain things, like that despite good-faith efforts it cannot get enough suitable coal or other fuel at a cost that is not much higher than using imported oil; or the site has physical limits; or meeting the ban would break environmental rules. Exemptions must also be granted if the plant shows it will switch to a synthetic fuel by the end of the exemption but cannot do so until then, or will adopt a new “innovative” coal technology by the end of the exemption, or will retire before the exemption ends, or will run only as a peakload plant, or if the exemption is needed to prevent loss of reliable service. The Secretary may also grant an exemption if doing so is in the public interest. Some exemptions require the plant to file and keep a compliance plan that meets the rules in section 8354(b). Most temporary exemptions cannot last more than 5 years in total, including extensions. The exemption for lack of alternate fuel (the cost/availability finding) can be up to 10 years. Exemptions based on future synthetic fuels, innovative technologies, or reliability may be extended past 5 years but not beyond 10 years. Exemptions for retirement, peakload use, or reliability that allow natural gas cannot go past December 31, 1994. When counting the 5- or 10-year limits, ignore any time before the ban would first have applied.
