(1) Annual Arithmetic Mean
(2) Not to be exceeded More than Once per Year
(3) Annual Geometric Mean. The standard is attained when the expected arithmetic mean concentration is equal to or less than the numerical standard as determined by Appendix K Part 50 CFR 40.
(4) Measured between 6 a.m. and 9 a.m.
(5) The standard is attained when the expected number of days per calendar year with maximum hourly average concentrations above 0.12 parts per million is equal to or less than 1, as determined by Appendix H for Part 50 of Chapter I, CFR 40.
(6) Guide only value to EPA, to be used in planning, not a Federal standard.
(7) Maximum arithmetic mean averaged over a calendar quarter.
