RE: Case No. NT-G-17-03 - Supplemental Filing
Dear Ms. Hanian
This supplemental filing to the above referenced Case includes an original and seven (7) copies of
Intermountain Gas Company's Rate Schedule DSM, which was previously authorized in Case No. INT-G-
16-02. Also enclosed, is the Company's proposed cancelation of Rate Schedule ER.
Although the Company received approval from the Commission to implement Rate Schedule DSM in Case
No. INT-G-16-02, the Company proposes to make the implementation of the same contingent upon the
Commission's approval of the Company's proposed Rate Schedule DSM Charge.
Furthermore, the Company proposes to make the cancelation of Rate Schedule ER contingent upon the
approval and implementation of the above rate schedules which would render Rate Schedule ER obsolete
due to the new rebate program introduced in Rate Schedule DSM.
Should the Commission deny the implementation of Rate Schedule DSM Charge, the Company will
consider an additional filing to withdraw Rate Schedule DSM and reinstate Rate Schedule ER.
If you should have any questions regarding this supplemental filing please contact me at377-6168
Sincerely,
Intermountain Gas Company
