(1) The requirements of the state implementation plan for prevention of significant deterioration of ambient air quality shall not apply to a major stationary source or major modification with respect to a particular pollutant if the owner or operator demonstrates that:
As to the pollutant, the source or modification is subject to part 3 of this article, andthe source or modification would impact no area attaining the national ambient air quality standards (either internal or external to areas designated as nonattainment under section 107 of the federal act); or
(Deleted by amendment, L. 92, p. 1229, § 27, effective July 1, 1992.)
Such emissions would be from a temporary activity which will not have an adverseimpact on air quality in any class I area or an area where an allowable increase over the baseline concentration is known to be violated; except that such temporary activities shall be subject to requirements related to the employment of best available control technology; or (d) Such emissions would not be significant.
(2) The following pollutant concentrations shall be excluded in determining compliance with maximum allowable increases:
Concentrations attributable to the increase in emissions from sources which haveconverted from the use of petroleum products, natural gas, or both, by reason of an order in effect under section 2(a) and (b) of the federal "Energy Supply and Environmental Coordination Act of 1974" (or any superseding legislation) over the emissions from such sources before the effective date of such an order, but not more than five years after the effective date of such an order;
Concentrations attributable to the increase in emissions from sources which haveconverted from using natural gas by reason of a natural gas curtailment plan in effect pursuant to the federal "Power Act" over the emissions from such sources before the effective date of such plan but not more than five years after the effective date of the plan; and
(Deleted by amendment, L. 92, p. 1229, § 27, effective July 1, 1992.)
Concentrations of particulate matter attributable to an increase in emissions fromtemporary activity.
