a Measured at the combustor outlet in conjunction with a measurement of oxygen concentration, corrected to 7 percent oxygen (dry basis). CEMS data during warmup, startup, and shutdown, as defined in this subpart, are not corrected to 7 percent oxygen, and are used as measured. The averaging times are specified in greater detail in § 60.5940(b).
b Averaging times are 4-hour or 24-hour block arithmetic averages.
