Additional Comments:
August 61h, 2025: Inspector Galli traveled to Afton, WY to conduct construction inspection along Crow
Creek Road towards Montpelier, ID. (Galli 0.5)
Observations included: pipe stringing, material verification, inspection of completed butt fusions, line
markers, operator qualification, equipment qualifications and tracer wire installation in trenches.
Discrepancies:
1. Fusion procedures state 500 degrees +/- 10 degrees in several places.
2. Unable to determine what butt fusion standard they follow in their procedures.
3. Only observed two-line markers along 40 miles of right of way. Need to verify more line markers
will be installed.
