Tinnerstet at the Nampa LNG Facility to conduct an audit of records for plant operations and field
observation for the 2023 calendar year. The PHMSA Inspection Assistant(IA) Program was used as a
guide while reviewing multiple documents to include the Operations and Training Manuals, OQ
records and inspection data and notes. An IA Post Inspection Preliminary Findings (exit interview) was
performed.

Completed forms and typed report. Results were listed on IA Post Inspection Preliminary
Findings.
Discrepancies:
IPUC inspectors observed the calibration gas for the portable gas detectors had been expired
since 11/2023. Additionally, the physical support structures for the cable racks outside the control room
had noticable grout spalling. LNG Technicians were actively working with the contractor to
address the grout issue. Wrote NOPV I202420.
