RE: Case No. RUL-U-26-01, Intermountain Gas Company comments on draft changes
to IDAPA 31.01.01, Rules of Procedure of the Idaho Public Utility Commission
Dear Ms. Barrios-Sanchez:
Intermountain Gas Company("Intermountain"or"Company") respectfully submits the
following written comments on the proposed changes to IDAPA 31.01.01, Rules of
Procedure of the Idaho Public Utility Commission ("IPUC"or"Commission"), issued in
Case No. RUL-U-26-01 as part of the negotiated rulemaking process.
Intermountain Comments
Rule 125. Notices To Customers Of Proposed Changes In Rates, Paragraph 01
Contents of Customer Notice, Subpart b.
In response to the IPUC Staff question that asks if customers should be notified of rate
decreases, Intermountain believes such notifications should not be mandatory. Rather,
notification of bill decreases should be at the discretion of the utility.
Rule 141 Form And Contents Of Application To Issue Securities, Paragraph 08
Statement of Public Notice Application
Although no edits were proposed by the Commission Staff relating to this rule,
Intermountain contends that the requirement to publish notice of securities applications is
outdated and should be removed. Newspaper circulation has declined significantly over
the past two decades, while advertising costs have increased. Accordingly, the Company
recommends that Rule 141.08 be eliminated.

Case No. RUL-U-26-01

Alternatively, if the Commission determines that some form of notice should be retained,
Intermountain recommends allowing issuance of a press release to local media outlets in
place of newspaper publication.
Generally
Intermountain supports the IPUC's proposed changes overall. The edits appear thoughtful
and are likely to improve the clarity and administration of the rules.
Intermountain appreciates the opportunity to provide comment in this proceeding. If you
have questions, please contact Jacob Darrington at [phone].
Sincerely,
Is/Michael Parvinen
