RECOMMENDATION: Resample in  year.

*In-Service Norms as follows -
Generating              Transmission
H2       240 ppm                 100 ppm
CH4      160 ppm                 120 ppm
C2H2      11 ppm                  35 ppm
C2H4     190 ppm                  30 ppm
C2H6     115 ppm                  65 ppm
CO       580 ppm                 350 ppm
The above analyses were performed using the TOGAS direct injection system
rather than the vacuum extraction method described in ASTM D3612.
