Dear Mr. Darras:
On 31 Aug-2 Sep, 2020, representatives of the Idaho Public Utilities Commission, Pipeline
Safety, pursuant to Chapter 601 of Title 49, United States Code, conducted an onsite specialized
field inspection in your Idaho Falls District.
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 2020.
The item(s) listed below are of concern:
1. Cascade Natural Gas Corporation-OPS 703 (Sec 8), 8.1.5-reads: If a plug is not
adequately lubricated, apply valve sealant. (Inability to operate without
significant force is on indication of inadequate lubrication.) Refer to section 6.
Emergency Valve 700 0226 is not able to be operated without significant force (takes 2
personnel to operate).
The above mentioned items were brought to the attention of your representatives during the
onsite inspections. We would request that you review these matters and respond in writing
within 30 days regarding the above issue including any planned corrective actions.
If you have any questions concerning this notice, please contact me at [phone]. All
written responses should be addressed to me at: 11311 W Chinden Blvd, Ste 201-A, Boise,
