Measurements of Releases to Atmosphere
USEPA Method 1:
This method will be used for the sample and velocity traverse for stationary sources. The method is designed to aid in the representative measurement of pollutant emissions and/or total volumetric flow rate from a stationary source.
USEPA Method 2:
This method is applicable for the determination of the average velocity and the volumetric flow rate of a gas stream which will be determined from the gas density and from measurement of the average velocity head with a Type S pitot tube.
SUSEPA Method 3:
This method is applicable for the determination of the moisture content of stack gas, A gas sample is extracted at a constant rate from the source; moisture is removed from the sample stream and determined volumetrically (or gravimetrically).
SUSEPA Method 5:
Method 5 will be used for the determination of particulate matter (PM) emissions from stationary sources. Particulate matter will be withdrawn isokinetically from the source and collected on a glass fiber filter maintained at a temperature of 120 ±14 °C (248 ±25 °F).
