Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER IV–A — ACID DEPOSITION CONTROL › § 7651b
The law requires the Administrator to give each affected power-plant unit a number of sulfur dioxide (SO2) allowances each year equal to that unit’s annual emissions limit. Beginning January 1, 2000, total SO2 emissions from utility units must not exceed 8.90 million tons per year, and the Administrator may cut Phase II allowance amounts across the board to meet that cap. Allowances are given free unless the Administrator sells some. The Administrator had to publish a proposed list of Phase II allocations by December 31, 1991, and a final list after public comment by December 31, 1992, with a revised final statement due before June 1, 1998. Owners who needed to make certain deadline or allocation choices had to notify the Administrator by March 31, 1991 (or June 30, 1991, in one case). The law lets allowance holders trade and transfer allowances under rules the Administrator must make within 18 months after November 15, 1990. Rules must track, record, and prevent use of allowances before the year they apply to, allow unused allowances to be carried forward, and require written certification and recording for transfers. The Administrator must also set up an allowance tracking system in that same 18-month period. Transfers can be recorded before official allocation, but pre-allocation transfers are then removed from the transferor’s allocation and added to the transferee’s. Emergency or short-term shifts of emissions inside utility systems or pools don’t require transfers as long as the pool’s total yearly emissions don’t exceed its total allowances. New utility units cannot emit more SO2 after January 1, 2000 than the allowances they hold. Allowances are a limited permission to emit, not a property right, and must be used only as the rules allow; emitting more than the allowances for a unit is illegal. The Administrator must report to Congress by January 1, 1994 on the idea of trading SO2 allowances for nitrogen oxides allowances. The law does not change antitrust laws, state utility-rate rules, the Federal Power Act, or certain bidding programs; and acquiring or selling allowances is not subject to the Public Utility Holding Company Act of 1935.
