During any 30 consecutive days, the arithmetic mean of the 24-hour average concentrations, at any location, shall not exceed:
Level I | 80 μg/m3 | Level III | 115 μg/m3 |
Level II | 100 μg/m3 | Level IV | 135 μg/m3 |
(b) 60-day standard.
During any 60 consecutive days, the arithmetic mean of the 24-hour average concentrations, at any location, shall not exceed:
Level I | 70 μg/m3 | Level III | 95 μg/m3 |
Level II | 85 μg/m3 | Level IV | 115 μg/m3 |
(c) 90-day standard.
During any 90 consecutive days, the arithmetic mean of the 24-hour average concentrations, at any location, shall not exceed:
Level I | 65 μg/m3 | Level III | 90 μg/m3 |
Level II | 80 μg/m3 | Level IV | 105 μg/m3 |
(d) The standards in subdivisions (a), (b) and (c) of this section are intended for enforcement purposes, and monitoring will be performed only as required in a particular area. For prediction purposes, prediction of conformity with the annual geometric mean standard shall be sufficient to demonstrate predicted conformity with these standards.
