(A) VOC offset requirements for ozone nonattainment areas are as follows:

(1) In areas that are not classified as marginal, moderate, serious, severe or extreme areas, the offset ratio shall be greater than 1.0 to 1.0

(2) Marginal areas, the minimum required offset ratio is 1.1 to 1.0.

(3) Moderate areas, the minimum required offset ratio is 1.15 to 1.0.

(4) Serious areas, the minimum required offset ratio is 1.2 to 1.0.

(5) Severe areas, the minimum required offset ratio is 1.3 to 1.0.

(6) Extreme areas, the minimum required offset ratio is 1.5 to 1.0.

(7) Offsets may be obtained from areas that have a higher nonattainment classification (provided the higher offset ratio is utilized) than the nonattainment area in which the major stationary source is to be located.

(B) Nitrogen oxides

The emission of nitrogen oxides from stationary sources shall be treated as a nonattainment air pollutant in each county that is designated nonattainment for ozone. The offset requirements listed for ozone in paragraph (A) of this Rule shall apply to nitrogen oxide emissions as well. These requirements do not apply in areas that have been granted a nitrogen oxide waiver under Section 182(f) of the Clean Air Act.

(C) Other criteria air pollutants

For sulfur dioxide, carbon monoxide, particulate matter, and lead the offset ratio shall be greater than 1.0 to 1.0.
