More Definitions of Averaging time

Averaging time means the time period over which air pollutant concentrations are averaged for the purpose of determining attainment with the emission standard using Continuous Emission Monitoring Systems (CEMS). The sub-average period for determining a half-hour average is a 1-minute average. A valid half hour average must contain at least 22 sub-average data within a half-hour period (75%). A valid 1-minute average must contain valid data readings representing any 45 seconds over the previous 1-minute period;
