Non-attainment provisions - offset ratio requirements.

(A) In meeting the emissions offset in Rules 210A to 210G of the RCAP, the following shall occur: (1) The ratio of total actual emissions reductions to the emissions increase shall be at least greater than 1.0 to 1.0 unless an alternative ratio is provided for the applicable non- Page 57 attainment area in paragraphs (C) and (D) of this Rule or in any non-attainment area rule in Part IV of the RCAP. (2) The emissions offsets obtained shall be for the same regulated NSR pollutant. (B) Offsets may be obtained from areas that have a higher non-attainment classification, provided the higher offset ratio is utilized, than the non-attainment area in which the major stationary source is to be located. (C) Ozone non-attainment area offset requirements for VOC and nitrogen oxides are as follows: (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. (D) Reserved (E) Nitrogen oxides waiver. Paragraph (A) of this Rule shall not apply in areas designated non-attainment for ozone that have been granted a nitrogen oxide waiver under Section 182(f) of the Clean Air Act.
