The concentration of NO2 at the 99th percentile, for each monitoring station with population representativity for gases (EMRPG). The concentration values (ppbv or µg/m3N), consisting of a calendar year of measurement, will be noted in a list arranged in increasing order that enables the accumulated concentration at 99% to be identified. The primary air quality standard for the annual concentration of nitrogen dioxide shall be considered excessive when the arithmetic mean of the annual concentration values of three successive calendar years at any EMRPG monitoring station is greater than or equal to 53 ppbv. The concentration of one hour shall also be considered excessive when the arithmetic mean of three successive years of the 99th percentile of the daily maximum concentrations of one hour recorded during a calendar year at any EMRPG monitoring station is greater than or equal to 213 ppbv.
