Intermountain Gas Response
IGC acknowledges the findings brought forth by the IPUC. In response to this occurrence, IGC's Quality
Management Systems(QMS)department will revise the inspection protocol to ensure inspection of equipment
calibration due dates are included when butt fusions are being performed. If unable to provide record of
calibration onsite during a field inspection, QMS inspectors will issue a nonconformity report against the
contractor.Forty-eight(48)hours will be provided to the contractor to verify record of calibration. If unable to
provide record of calibration, further action will be taken with the contractor.
Additionally,IGC has initiated an MOC to revise OPS 501—Equipment Calibration,Maintenance, and Testing
adding guidance for contractors to have equipment calibration records on the jobsite. Notification will be
provided to contractors of this change.
The revised protocol and revised OPS 501 are expected to implement before July 1, 2022.
