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: | - |
| Annual arithmetic mean | 2 |
| Twenty-four hour maximum | 5 |
| Three-hour maximum | 25 |
| Nitrogen dioxide: | - |
| (effective May 11, 1991) Annual arithmetic mean |
