I hereby certify the accuracy of the data contained in this report.____________________________________________________________ 

 Date

 Because the implementation of some technologies reduces emissions for multiple years, Natural Gas STAR allows certain activities to count 

towards a company’s emission reductions beyond the initial year of implementation. Natural Gas STAR designates the maximum length of time 

that these reductions may accrue as “sunset dates.” The Appendix lists these sunset dates. Companies can report the corresponding methane 

emission reductions each year up to the allowable sunset date. Or, companies may wish to report reductions only once for the implementation 

year, and have EPA automatically apply the sunset date and count those emissions for the allowable number of years. 

 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.
