NOTICE OF INVESTIGATION

ORDER NO. 28632

YOU ARE HEREBY NOTIFIED that the Commission has found it appropriate to initiate
investigation into Intermountain Gas Company’s Purchase Gas Adjustment (PGA) mechanism and
its natural gas purchasing policies in Order No. 28578 (Case No. INT-G-00-2). The Commission
noted that:
Although the PGA passes the savings through to customers when
Intermountain Gas buys gas more inexpensively than projected, it also passes
on the additional cost of gas purchased in excess of the projected price. While
there is no evidence to suggest that the costs passed through to the ratepayers
have not been just and reasonable, we question why some prices were not
locked in to hedge against the current market volatility.

A formal review could result in rewards for both the customers and the
Company through profit sharing and administrative savings. We find that
attributes (such as benchmarking or sharing) included in other utility PGA
mechanisms could potentially benefit Intermountain’s customers if they were
incorporated in Intermountain’s PGA mechanism. In light of the current
volatile market conditions, it is imperative that the Commission and
Intermountain’s customers are assured that the PGA mechanism is equitable
and that natural gas is secured at the most reasonable price possible. A review
at this time would provide such assurance and is in the public interest. A PGA
review will also facilitate examination of the Company’s gas purchasing
policies, alternative gas suppliers, and management fees it pays to IGI
Resources as required by Order No. 28109 (Case No. INT-G-99-1). To assist
with this PGA review, Intermountain Gas is directed to prepare and submit an
analysis of its gas purchasing policies and gas supplies.

YOU ARE FURTHER NOTIFIED that Intermountain Gas was required by Order No.
28578 in Case No. INT-G-00-2 to analyze the cost-effectiveness of its relationship with its gas
suppliers and gas purchasing policies, and file results of that analysis with the Commission to

investigation. Upon completion of this investigation, Staff is to file a written report of its findings,
recommendations and a proposed process to complete this case.
