(1) Annual arithmetic mean
(2) Not to be exceeded more than once per year
(3) Not to be exceeded more than once during a 3-year period as provided
in 40 CFR 50, Appendix R.
(4) The standard is attained when the computed 3-year average of the annual
4th-highest daily maximum 8-hour average does not exceed 0.075 ppm, as
provided in 40 CFR 50.15.
(5) The standard is attained when the 98th percentile concentration is equal
to or less than the numerical standard as determined by 40 CFR 50, Appendix N.
(6) The standard is attained when the annual arithmetic mean is equal to or less
than the numerical standard as determined by 40 CFR 50, Appendix N.
(7) The standard is attained when the expected number of days per calendar
year with a 24-hour average concentration above 150 ug/m3, as determined in
accordance with 40 CFR 50, Appendix K is equal to or less than one.
(8) The standard is attained when the 3-year average of the 99th percentile of
the daily maximum 1-hour average at each monitor within an area does not
exceed 75 ppb, as determined in accordance with 40 CFR 50, Appendix T.
(9) The standard is attained when the 3-year average of the 98th percentile of
the daily maximum 1-hour average concentration at each monitor within an area
does not exceed 100 ppb as determined in accordance with 40 CFR 50, Appendix S.
