Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER IV–A — ACID DEPOSITION CONTROL › § 7651c
Starting January 1, 1995, any power plant unit listed in Table A must keep its annual sulfur dioxide (SO2) emissions at or below the number of tons of allowances assigned to that unit. A unit may meet this by making required reductions or by holding enough allowances to cover its yearly emissions. After January 1, 2000, these Phase I rules are replaced by Phase II rules. Owners who break the rules are fully responsible for the violation. The EPA Administrator had to calculate, by December 31, 1991, how many tons of SO2 would be cut by 1995 and set up a reserve of allowances up to 3.50 million tons. The Administrator’s calculation uses each unit’s baseline, 1985 emission rates, an emission rate of 2.50 lbs/mmBtu, division by 2,000, and adjustments for expected 1995 use. In 1995–1999 the Administrator must also give extra allowances for units in Illinois, Indiana, and Ohio equal to 200,000 times each unit’s share of those States’ Table A allocations. A unit owner may propose to move its reduction obligation to other units they control, but EPA must approve the swap and the substitute units then become covered by the program. An owner can ask for a 2-year delay if the unit will use qualifying Phase I technology or transfer its obligation to a unit that will; such petitions must include contracts, baselines, projected use, and require continuous emissions monitors by January 1, 1995. The Administrator will allocate reserve allowances for approved extensions using formulas that involve 2.50 lbs/mmBtu, 1.20 lbs/mmBtu, division by 2,000, and a factor of 3. For energy conservation and renewable power, the Administrator will set rules so that one allowance is given for each ton of SO2 avoided, up to 300,000 allowances total, for measures in effect after January 1, 1992 and before December 31, 2000; avoided emissions are calculated using kilowatt hours times 0.004 divided by 2,000. The law also creates a Conservation and Renewable Energy Reserve and requires regulations within 18 months after November 15, 1990. Certain low-emitting units may choose an optional baseline method if they meet specific tests (including below 1.0 lbs/mmBtu and a 60% drop since 1980) by March 1, 1991.
