Finding(s)•
At 1317 S Sabrina Ave,Kuna,ID,IPUC inspectors observed 6 feet of live 3/a"PE pipe installed above grade
and tied to a live electric meter by the associated tracer wire.Das-Co employees properly identified and
reported the Abnormal Operating Condition(AOC)to their supervisor and to IGC District Operations
Coordinators,yet no IGC personnel responded to the jobsite. IPUC inspectors notified IGC Compliance
Personnel.The ELM employee responsible for the locates failed to appropriately recognize and react to
AOC's.
Intermountain Gas Resnonse
On May 14, 2025, Das-Co arrived at 1317 S Sabrina Ave to extend the service stub. Upon arrival, it was
discovered that the stub was exposed and strapped to a temporary power meter.Das-Co contacted an IGC District
Operations Coordinator (DOC). Das-Co advised the DOC they were going to inspect the service stub and cut
out any signs of damage before extending the service to the meter. Due to the abnormal operating condition
(AOC)being mitigated by extending the stub, a site visit by the DOC was not needed.
Per OPS 611 — Line Locating and Marking section 1.9., In gas only districts, MDUG first- and second party
contractors should locate gas facilities within the scope of the line locate ticket for the MDUG project they are
constructing. With Das-Co performing the stub extension on behalf of IGC, ELM did not perform the line
locates for gas facilities.
