Electric utilities are subject to stringent emission reduction requirements under section 401 of the Clean Air Act Amendments of 1990 (CAAA) (42 U.S.C.A. § 7651). An innovative market-based system for the trading of allowances for the emission of sulfur dioxide was established under the CAAA in order to substantially reduce the cost of compliance with the Clean Air Act (See 42 U.S.C.A. § 7651b(b)). Because of the importance of allowance trading to the cost-effective implementation of the CAAA, the Commission promulgated the guidelines in this section and § § 69.292-69.294 to help facilitate a liquid allowance trading market.
