257-3.3 Standard for suspended particulates.
(a) 24-hour standard. For any 24-hour period, the average concentration shall not exceed 250 μg/m3 more than once a year. (Applicable in all levels.)
(b) Annual standard.
During any 12 consecutive months, the geometric mean of the 24-hour average concentrations shall not exceed:
Level I45 μg/m3Level III65 μg/m3
Level II55 μg/m3Level IV75 μg/m3
(c) 30-day standard.
During any 30 consecutive days, the arithmetic mean of the 24-hour average concentrations, at any location, shall not exceed:
Level I80 μg/m3Level III115 μg/m3
Level II100 μg/m3Level IV135 μg/m3
(d) 60-day standard.
During any 60 consecutive days, the arithmetic mean of the 24-hour average concentrations, at any location, shall not exceed:
Level I70 μg/m3Level III95 μg/m3
Level II85 μg/m3Level IV115 μg/m3
(e) 90-day standard.
During any 90 consecutive days, the arithmetic mean of the 24-hour average concentrations, at any location, shall not exceed:
Level I65 μg/m3Level III90 μg/m3
Level II80 μg/m3Level IV105 μg/m3
(f) The standards in subdivisions (c), (d) and (e) 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.
