Gas STAR allows certain technologies/practices to count towards a company’s emission reductions beyond the year they were initially
implemented. For example, a technology implemented in 2007 can accrue emission reductions in future years. Gas STAR designates
the length of time that these reductions accrue as “sunset dates.” The Appendix lists these sunset dates. Companies can choose to
allow EPA to apply the sunset dates or choose to report each technology/practice on an annual basis (i.e. not using sunset dates).
In addition to reporting methane emissions reductions, you are welcome to include other information about your company’s participation
in Natural Gas STAR in the “Additional Program Accomplishments” section of this form. The Natural Gas STAR Program will use any
information entered in this section to recognize the efforts and accomplishments of outstanding partners.

Calculation using default

Methane emissions reduction per flash tank

F. Total value of gas saved:

*If methane entrainment
rate is not known, use a
default value of 3 scf/gal

pumps or 1 scf/gal for
electric pumps

Methane emissions reduction = [Average gas throughput (in MMcf/yr)
