Subject:Response to Letter of Concern dated April 11,2022(Report#1202201)
Dear Mr.Brooks,
This letter is intended to address an area of concern from a records audit conducted by the Idaho Public Utilities
Commission(IPUC)on March 28,2022,at Intermountain Gas Company's(IGC)Boise office.
ITEM OF CONCERN
1. § 192.756 Joining plastic pipe by heat fusion;equipment maintenance and calibration.
Each operator must maintain equipment used in joining plastic pipe in accordance with the
manufacturer's recommended practices or with written procedures that have been proven
by test and experience to produce acceptable joints.
Finding(s)•
During the inspection IPUC personnel asked how IGC verifies that their contractors are
complying with the above code requirement. IGC was unable to present records for
verification.
Intermountain Gas Response
IGC acknowledges these findings and will reeducate contractors of these responsibilities.Section 6 of OPS 501
—Equipment Calibration,Maintenance, and Testing states that contractors completing work on behalf of MDU
Utilities Group(MDUG)shall calibrate/maintain their equipment according to MDUG procedures.Contractors
are responsible for maintaining calibration records and providing those records upon request.
Additionally,IGC has initiated further action to help ensure our contractors are compliant with the procedure.
An MOC has been created to modify the company's field inspection form to add the verification of equipment
calibration when field staff are onsite to perform an internal inspection.
Please contact Josh Sanders at(701)222-7773 with questions or comments.
Respectfully Submitted,
