For each stack system for which you use the “stack test method” to calculate annual emissions, you must measure the following:If emissions are detected intermittently, use the
following procedures:
If emissions are not detected, use the
following procedures:
Expected By-products:
   CF4
   C2F6
   CHF3
   CH2F2
   CH3F
Use the measured concentration for “Xksm” in Equation I-18 when available and use one-half of the field detection limit you determined for the fluorinated GHG according to §98.94(j)(2) for the value of “Xksm” when the fluorinated GHG is not detectedUse one-half of the field detection limit you determined for the fluorinated GHG according to §98.94(j)(2) for the value of “Xksm” in Equation I-18.
Possible By-products:
   C3F8
   C4F6
   c-C4F8
   C5F8
Use the measured concentration for “Xksm” in Equation I-18 when available and use one-half of the field detection limit you determined for the fluorinated GHG according to §98.94(j)(2) for the value of “Xksm” when the fluorinated GHG is not detectedAssume zero emissions for that fluorinated GHG for the tested stack system.
