Dear:

Intermountain Gas Company values you as a customer and we are committed to meeting your expectations
by providing reliable energy services to your facility. We continue to see steady growth in natural gas
usage from all sectors of our business. That growth coupled with the real potential for extremely cold
winter weather emphasizes the importance of our long-term planning efforts.

An Order from the Idaho Public Utilities Commission (Commission) requires Intermountain to file an
Integrated Resource Plan (IRP) every two years. The IRP is comprehensive, long-term plan that gives the
Commission the opportunity to assess our forecast including its inputs, underlying methodologies and
conclusions. The process documents our forecasting efforts, encourages public involvement, and provides
assurance to our customers that Intermountain plans to meet your future energy needs in a prudent manner.

We are now beginning our next IRP process and I am writing to solicit your assistance. In order for the IRP
to be as accurate as possible, it is crucial that we obtain and incorporate your projected natural gas
requirements for the next several years. I have enclosed a survey form that requests information relative
projected changes in your facility’s annual and peak day natural gas requirements and alternate fuel plans.
To provide context, I have included historical annual and peak day (where available) therm use data for the
two most recent years.

I recognize the effort required for you to complete this survey but I assure you that it is important and we
will use the data in our IRP. Your data will improve the accuracy of our demand forecast which will help
Intermountain employ the resources necessary to provide all our customers with reliable, year-round
service. Please return your completed survey, including any comments or questions you may have, by
January 8, 2015. As always, any information you provide will be strictly confidential, will not be shared
with any other entity and will be aggregated with data from other customers in any public filing.

Should you have any questions or if I can be of assistance to you, please call me at [phone] or (208)
794-4118 or you can email me at [e-mail].

I thank you in advance,

David Swenson
Manager, Industrial Services
Intermountain Gas Company
