Dear Mr. Faulkenberry:
On March 6-7, 2018 representatives of the Idaho Public Utility Commission, Pipeline Safety Division,
conducted an onsite compliance inspection of Avista's pipeline safety records for the Idaho natural gas
distribution system owned and operated by Avista Utilities for calendar year 2017.
As a result of the inspection,it appears there is an area of concern that does not fully meet the intent of
the pipeline safety regulations Title 49,Code of Federal Regulations, Part 192 for calendar year 2017.
The item listed below is of concern:
1. § 192.747(a)Valve Maintenance: Distribution systems-reads: Each valve, the use of which may
be necessary for the safe operation of a distribution system, must be checked and serviced at
intervals not exceeding 15 months, but at least once each calendar year. Upon review of the
records,it was noted that valve LEC 709 was out of compliance regarding the required time
intervals.The valve in question was installed on Jan 8,2016 and was inspected on Apr 26, 2017.
The inspection was approximately two weeks past due.
The above mentioned item was brought to the attention of your representatives during the onsite
inspections.We would request that you review this matter and respond in writing within 30 days
regarding the above issue including any planned corrective action.
If you have any questions concerning this notice, please contact me at(208)334-0331.Also all written
responses should be addressed to me at: P.O. Box 83720-0074, Boise, Idaho 83720-0074 or you may fax
your response to(208)334-3762.
Because of the good faith that you have exhibited up to this time,we expect that you will act to bring
your program into compliance with pipeline safety regulations.

We appreciate your attention to this matter and your effort to promote pipeline safety.
