Table I-17 to Subpart I of Part 98—Expected and Possible By-Products for Electronics Manufacturing

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

C2 F6

CHF3

CH2 F2

CH3 F
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:

C3 F8

C4 F6

c-C4 F8

C5 F8
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.
