Date



###  Because the implementation of some technolog ies reduces emissions for multiple years, Natural Gas STAR allows certain activitie s to count towards a company’s emission reductions beyond the initial year of implementation. Natural Gas STAR designates the maximum leng th of time that these reductions may accrue as “sunset dates.” The Appendi x lists these sunset dates. Companies can report the correspondi ng methane emission reductions each year up to the allowable sunset date. Or , companies may wish to report reductions only once for the im plementation 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 ot her information about your company’s partic ipation in Natural Gas STAR in the “Additional Program Accomplishments” section of this form. The Natural Gas STAR Program will use any in formation entered in this section to recognize the effo rts and accomplishments of outstanding partners.
