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).

ƒ

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.

Other (please specify):

Calculation using default*
Methane emissions reduction = Average annual leak rate per facility
(1,700 Mcf) × Reduction efficiency (70%) × Number of facilities at
which leaking components were repaired
* Important note: The default value is to be used only for aboveground,
high-pressure (>300 psig) inlet facilities at which the guidelines
outlined in EPA’s Lessons Learned: Directed Inspection and
Maintenance at Gate Stations and Surface Facilities have been
applied. In addition, partners should only report reductions once per
year per facility and should verify that the default value is used only at
facilities where leak repairs were performed.

E. Total value of gas saved:

$

Total value of gas saved = Methane emissions reduction (in Mcf) x Gas

The public reporting and recordkeeping burden for this collection of information is estimated to
average 60 hours for each new response and 27 hours for subsequent responses. Send comments on the
Agency's need for this information, the accuracy of the provided burden estimates, and any suggested
