PUBLIC LAW 101-549—NOV. 15, 1990 104 STAT. 2429 "(ii) A percentage less than 15 percent may be used for purposes of clause (i) in the case of any State which demonstrates to the satisfaction of the Administrator that— "(I) new source review provisions are applicable in the nonattainment areas in the same manner and to the same extent as required under subsection (e) in the case of Extreme Areas (with the exception that, in applying such provisions, the terms 'major source' and 'major stationary source' shall include (in addition to the sources described in section 302) any stationary source or group of sources located within a contiguous area and under common control that emits, or has the potential to emit, at least 5 tons per year of volatile organic compounds); "(II) reasonably available control technology is required for all existing major sources (as defined in subclause (I)); and "(III) the plan reflecting a lesser percentage than 15 percent includes all measures that can feasibly be implemented in the area, in light of technological achievability. To qualify for a lesser percentage under this clause, a State must demonstrate to the satisfaction of the Administrator that the plan for the area includes the measures that are achieved in practice by sources in the same source category in nonattainment areas of the next higher category. "(B) BASELINE EMISSIONS. —For purposes of subparagraph (A), the term 'baseline emissions' means the total amount of actual VOC or NOx emissions from all anthropogenic sources in the area during the calendar year of the enactment of the Clean Air Act Amendments of 1990, excluding emissions that would be eliminated under the regulations described in clauses (i) and (ii) of subparagraph (D). "(C) GENERAL RULE FOR CREDITABILITY OF REDUCTIONS.— Except as provided under subparagraph (D), emissions reductions are creditable toward the 15 percent required under subparagraph (A) to the extent they have actually occurred, as of 6 years after the date of the enactment of the Clean Air Act Amendments of 1990, from the implementation of measures required under the applicable implementation plan, rules promulgated by the Administrator, or a permit under title V. "(D) LIMITS ON CREDITABILITY OF REDUCTIONS. — Emission reductions from the following measures are not creditable toward the 15 percent reductions required under subparagraph (A): "(i) Any measure relating to motor vehicle exhaust or evaporative emissions promulgated by the Administrator by January 1, 1990. "(ii) Regulations concerning Reid Vapor Pressure promulgated by the Administrator by the date of the enactment of the Clean Air Act Amendments of 1990 or required to be promulgated under section 211(h).
