    (a) Significant deterioration, as used in the phrase Prevention of Significant Deterioration (PSD),
means an increase in ambient air pollution above a baseline plus a specific increment allowed for
one of three classes of areas. See OAC 252: J00-8, Part 7.
    (b) The allowable increments are as follows:
        (1) Class I Areas:
            (A) PM_2.5 (effective October 20, 2011):
                (i) annual arithmetic mean: maximum allowable increase is 1 microgram per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 2 micrograms per cubic meter.
            (B) PM₁₀:
                (i) annual arithmetic mean: maximum allowable increase is 4 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 8 micrograms per cubic meter.
            (C) Sulfur dioxide:
                (i) annual arithmetic mean: maximum allowable increase is 2 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 5 micrograms per cubic meter.
                (iii) three-hour maximum: maximum allowable increase is 25 micrograms per cubic meter.
            (D)  Nitrogen dioxide (effective May 11, 1991), annual arithmetic mean: maximum allowable increase is 2.5 micrograms per cubic meter.
        (2) Class II Areas:
            (A) PM_2.5 (effective October 20.2011):
                (i) annual arithmetic mean: maximum allowable increase is 4 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 9 micrograms per cubic meter.
            (B) PM₁₀:
                (i) annual arithmetic mean: maximum allowable increase is 17 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 30 micrograms per cubic meter.
            (C) Sulfur dioxide:
                (i) annual arithmetic mean: maximum allowable increase is 20 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 91 micrograms per cubic meter.
                (iii) three-hour maximum: maximum allowable increase is 512 micrograms per cubic meter.
            (D) Nitrogen dioxide (effective May 11, 1991), annual arithmetic mean: maximum allowable increase is 25 micrograms per cubic meter.
        (3) Class III Areas:
            (A) PM_2.5 (effective October 20, 2011):
                (i) annual arithmetic mean: maximum allowable increase is 8 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 18 micrograms per cubic meter.

                (i) annual arithmetic mean: maximum allowable increase is 34 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 60 micrograms per cubic meter.
            (C) Sulfur dioxide:
                (i) annual arithmetic mean: maximum allowable increase is 40 micrograms per cubic meter.
                (ii) twenty-four hour maximum: maximum allowable increase is 182 micrograms per cubic meter.
