This rule applies to any major stationary source or major modification that is to be constructed in an area designated in 40 CFR 81.336 as nonattainment for an air pollutant for which the major stationary source or major modification is major.
(B) Volatile organic compounds (VOC), and nitrogen oxides
In the case of emission offsets involving VOCs, and nitrogen oxides, the offsets may be obtained from:
(1) Within the same demonstration area as the new major stationary source or major modification, or
(2) Outside the same demonstration area if the applicant demonstrates to the director's satisfaction that the net combined impact of the emissions from the offsetting sources and emissions from the new major stationary source or major modification will have a positive net air quality benefit on the nonattainment ozone air quality in the area.
(C) Sulfur dioxide, particulate matter, PM10, lead and carbon monoxide
Since the air quality impact of sulfur dioxide, particulate matter, PM10, lead and carbon monoxide is site dependent, simple area wide mass emission offsets may not be appropriate. For these air pollutants, the director may require atmospheric dispersion modeling to ensure that the emission offsets provide a positive net air quality benefit. This modeling shall be conducted in accordance with the director's guidance.
