§3175.119. Components to analyze.
43 C.F.R. § 3175.119
The gas must be analyzed for the following components:
Methane;
Ethane;
Propane;
Iso Butane;
Normal Butane;
Pentanes;
Hexanes + (C6+);
Carbon dioxide; and
Nitrogen.
When the concentration of C6+ exceeds 0.5 mole percent, the following gas components must also be analyzed:
Hexanes;
Heptanes;
Octanes; and
Nonanes +.
In lieu of testing each sample for the components required under paragraph (b) of this section, the operator may periodically test for these components and adjust the assumed C6+ composition to remove bias in the heating value (see § 3175.126(a)(3)). The C6+ composition must be applied to the mole percent of C6+ analyses until the next analysis is done under paragraph (b) of this section. The minimum analysis frequency for the components listed in paragraph (b) of this section is as follows:
For high-volume FMPs, once per year; and
For very-high-volume FMPs, once every 6 months.
