252:100-3-1. Purpose

The purpose of this Subchapter is to enumerate the primary and secondary ambient air quality standards and the significant deterioration increments.

252:100-3-2. Primary standards

The table in Appendix E of this chapter enumerates the primary ambient air quality standards.

252:100-3-3. Secondary standards

The table in Appendix F of this Chapter enumerates the secondary ambient air quality standards.

252:100-3-4. Significant deterioration increments

(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 252:100-7, Part 5.
(b) The allowable increments are as follows:

Pollutant	Maximum allowable increase (micrograms per cubic meter)
Class I Areas	-
Particulate matter:	-
Annual geometric mean	5
Twenty-four hour maximum	10
Sulfur dioxide:	-
