Dear Mr. Darras:
On January 25, 2021 representatives of the Idaho Public Utilities Commission, Pipeline Safety,
pursuant to Chapter 601 of Title 49, United States Code, conducted an onsite construction
inspection of the 318-57FS-123 project located at 605 N 7th St, in Parma, Idaho.
As a result of the inspection, it appears there are area(s) of concern that do not fully meet the
intent of the pipeline safety regulations Title 49, Code of Federal Regulations, Part 192 for
calendar year 2021.
The item(s) listed below are of concern:
1. § 192.605(a) General. Each operatorshall prepare and follow for each pipeline, a
manual of written procedures for conducting operations and maintenance activities and
for emergency response. For transmission lines, the manual must also include
procedures for handling abnormal operations. This manual must be reviewed and
updated by the operator at intervals not exceeding 15 months, but at least once each
calendar year. This manual must be prepared before operations of a pipeline system
commence. Appropriate parts of the manual must be kept at locations where operations
and maintenance activities are conducted.
During the inspection it was noted that the DAS-CO welding crew employed by IGC, when asked
about preheating prior to welding, did not have a operational and calibrated infrared
pyrometer to check the preheat temperature at the weld groove and weld area as required by
IGC Operations and Maintenance Manual procedure 4106.1 (1.16.1). This area of concern has
been a previous issue brought to your company's attention.
