The primary ambient air quality standards for particulate matter are: 1) An. annual geometric mean concentration of 7S micrograms per cubic meter; and. 2) A maximum 24-hour concentrat ton not to be esceeded more than once per year of 260 micrograms per cubic meter. b) Secondary Standards. The secondary ambient air quality standards for particulate flutter are: 1) An annual geometric mean concentration of 60 micrograms per cubic meter; and. 2) A maximum 24-hour concentration not to be esceeded more than once per year of ISO micrograms per cubic meter. c) Measurement Method.
