Current through Register Vol. 41, No. 3, September 23, 2024

A. The owner of the proposed source or modification shall demonstrate that allowable emission increases from the proposed source or modification, in conjunction with all other applicable emissions increases or reductions (including secondary emissions), would not cause or contribute to air pollution in violation of:

1. Any ambient air quality standard in any air quality control region; or

2. Any applicable maximum allowable increase over the baseline concentration in any area.

B. The following applies to any new major stationary source or major modification if it would cause or contribute to a violation of any ambient air quality standard.

1. A new major stationary source or major modification will be considered to cause or contribute to a violation of an ambient air quality standard when such source or modification would, at a minimum, exceed the following significance levels at any locality that does not or would not meet the applicable air quality standard:

Pollutant

Annual

SO2

1.0 µg/m3

5.0 µg/m3

25.0 µg/m3

PM10

5.0 µg/m3

PM2.5

0.3 mg/m3

1.2 mg/m3

NO2

1.0 µg/m3

CO

500 µg/m3

2000 µg/m3

2. A proposed new major stationary source or major modification may reduce the impact of its emissions upon air quality by obtaining sufficient emission reductions to, at a minimum, compensate for its adverse ambient impact where the new major stationary source or major modification would otherwise cause or contribute to a violation of any ambient air quality standard. In the absence of such emission reductions, the department will deny the proposed construction.

3. The requirements of this subsection do not apply to a major stationary source or major modification with respect to a particular pollutant if the owner demonstrates that, as to that pollutant, the source or modification is located in an area designated as nonattainment in 9VAC5-20-204.
