Subject:Response to Notice of Probable Violation dated February 17,2021 (Report#I202102)
Dear Mr.Ulmer,
This letter is intended to address one probable violation stemming from a February 8,2021 training program
inspection which included plastic pipe joining for Intermountain Gas Company(IGC)personnel in Twin Falls,
Idaho. Specifically,we are addressing the details brought forth by the Idaho Public Utility Commission(IPUC)
stated below.
PROBABLE VIOLATION
1. 49 CFR &192.605 Procedural manual for operations, maintenance, and emergencies. (a)
General.
Each operator shall prepare and follow for each pipeline, a manual of written procedures for
conducting operations and maintenance activities and for emergency response.For transmission
lines, the manual must also include procedures for handling abnormal operations. This manual
must be reviewed and updated by the operator at intervals not exceeding 15 months, but at least
once each calendar year. This manual must be prepared before operations of a pipeline system
commence.Appropriate parts of the manual must be kept at locations where operations and
maintenance activities are conducted.
Finding:
During the inspection it was noted that after the classroom training, the personnel went into the
warehouse for the hands-on evaluation.It was observed that the pyrometer being used to test the heating
element was out of calibration(1/31/2021)thus in violation of OPS 501.This topic has been a previous
issue brought to your company's attention multiple times.
Intermountain Gas Reslionse
IGC acknowledges that the pyrometer labeled with a calibration due date of January 31, 2021 (Pyrometer 1)
was present during the February 8, 2021 Plastic Joining Qualification Training. Twin Falls District personnel
reported that the calibration due date of Pyrometer 1 was checked prior to being used for a performance
evaluation. As such, the MDU Utilities Group (MDUG) SMS/Quality Assurance department performed an
investigation into the above finding.
The investigation included interviews with eight IGC employees directly or indirectly involved and validated
that Pyrometer 1 was not used for performance evaluations.IGC personnel mitigated the issue by purchasing a
new pyrometer(see Attachment A)to be utilized for performance evaluations; therefore,remaining compliant
with MDUG procedure, OPS 501 —Equipment Calibration, Maintenance and Testing, and moreover,49 CFR
192.605(a).
IGC is cognizant of IPUC concerns regarding equipment calibration and is working diligently to assess and
improve calibration tracking processes for the company and its Contractors. As stated in IGC's response to the
