WARNING LETTER
CERTIFIED MAIL - RETURN RECEIPT REQUESTED
January 31, 2018
Mr. Ron Jorgensen
Vice President – Operations and Gas Control
Dominion Energy Questar Pipeline, LLC
P.O. Box 45360
Salt Lake City, UT 84145
CPF 5-2018-1002W
Dear Mr. Jorgensen:
On June 5 through 9, 2017 and July 17 through 21, 2017, a representative of the Arizona
Corporation Commission (ACC), pursuant to Chapter 601 of 49 United States Code,
inspected your Arizona Dominion Energy Questar Pipeline segments: Line 90 and Line 92.
Records review for the 12-inch - Line 92 and the 16-inch- Line 90 facilities occurred in the
Salt Lake City, Utah offices during June 5 through 9, 2017. Field inspections for these
facilities were completed on July 17 through 21, 2017. These Arizona-based Dominion
Energy Questars’ pipelines stretch between the New Mexico and California State borders.
As a result of the inspection, it is alleged probable violations of the Pipeline Safety
Regulations, Title 49, Code of Federal Regulations (CFR) have been committed. The items
inspected and the probable violation(s) are:
1. § 192.491 Corrosion control records.
(c) Each operator shall maintain a record of each test, survey, or inspection
required by this subpart in sufficient detail to demonstrate the adequacy of
corrosion control measures or that a corrosive condition does not exist. These
records must be retained for at least 5 years, except that records related to



§192.465(a) and (e) and 192.475(b) must be retained for as long as the pipeline
remains in service.
Although the requested records were provided for review, they were not completed in a
correct manner and demonstrated insufficient detail to demonstrate the adequacy of corrosion
control measures. The documentation provided during the inspection of the 2015 annual
survey, lacked both the survey date and personnel identification for whom conducted the
survey; this was shown on page 3 of the survey. The documentation, on page 41, also lacked
the personnel identification for whom conducted the survey. For the 2016 annual survey
audit, page 3 lacked the personnel identification for whom conducted the survey as well.
2. §192.614 Damage prevention program.
(c) The damage prevention program required by paragraph (a) of this section
must, at a minimum:
(1) Include the identity, on a current basis, of persons who normally engage in
excavation activities in the area in which the pipeline is located.
(2) Provides for notification of the public in the vicinity of the pipeline and actual
notification of the persons identified in paragraph (c)(1) of this section of the
following as often as needed to make them aware of the damage prevention
program:
(i) The program's existence and purpose;
During the inspection, documentation was not available to establish that Dominion Energy
Questar Pipeline Company provided damage prevention/public awareness information to
Northern Pipeline Construction Company– Prescott Valley (NPL-PV). This was
demonstrated by “Questar Southern Trails Pipeline 2017 Inspection” mailer list omitting
NPL-PV as an existing excavator in areas where Dominion‘s pipeline is located; this omission
resulted in a lack of information concerning Dominion‘s damage prevention program from
being communicated or provided to NPL-PV.
3. §192.917 How does an operator identify potential threats to pipeline integrity
and use the threat identification in its integrity program?
(b) Data gathering and integration. To identify and evaluate the potential threats
to a covered pipeline segment, an operator must gather and integrate existing
data and information on the entire pipeline that could be relevant to the covered
segment. In performing this data gathering and integration, an operator must
follow the requirements in ASME/ANSI B31.8S, section 4. At a minimum, an
operator must gather and evaluate the set of data specified in Appendix A to
ASME/ANSI B31.8S, and consider both on the covered segment and similar non-
covered segments, past incident history, corrosion control records, continuing
surveillance records, patrolling records, maintenance history, internal inspection
records and all other conditions specific to each pipeline.

Dominion provided Patrol/Leak Survey documentation for Segment 13 (page 2), that was
conducted on April 8, 2015, and it lacked required record header information. This header
information documented the type of patrols done, the right-of-way condition, atmospheric
corrosion inspections and other data associated with the patrol survey. Without this relevant
information for the covered segment, the validity of the survey is questionable. Moreover, the
survey record provided to ACC indicated the patrol survey was completed “on foot” by one
individual for approximately 70-80 miles of right-of-way in one day. This amount and type
of patrolling seems unlikely, or even possible, for an individual to complete in the amount of
time stated in Dominion‘s records.
4. §192.736 Compressor stations: Gas detection
(b) Except when shutdown of the system is necessary for maintenance under
paragraph (c) of this section, each gas detection and alarm system required by
this section must–
(1) Continuously monitor the compressor building for a concentration of gas in
air of not more than 25 percent of the lower explosive limit;
Documentation provided during the June 5-9, 2017 records inspection demonstrated 1.)
Dominion‘s gas detector testing on June 3, 2014 at the Mohave Valley Station and 2.)
December 8, 2014 at the Cameron Station. These records contained results showing detection
levels had exceeded the “25 percent of the lower explosive limit (LEL)”. Documents also
showed upon completion of Dominion‘s testing at the above two locations, the higher settings
were left at these unacceptable documented levels.
To clarify the inspection results mentioned above, the Gas Detectors Inspection Report for
testing at the Mohave Valley compressor station, dated June 3, 2014, showed two methane
detectors for the engine and fuel gas sensors were discovered and left at 26 percent and 27
percent of the LEL. In addition, the Gas Detectors Inspection Report documented gas
detector testing at the Cameron compressor station, dated December 8, 2014, showed the
methane detectors for the compressor, engine and generator sensors were found and left at 26
percent of the LEL. Additional data at this site revealed Sensor 3 was found at 25 percent of
LEL and was adjusted and left at 26 percent of the LEL. This means the concentration of gas
in air would be more than the prescribed 25 percent of the lower explosive limit. This is
because the alarming sensors have been left at excessive detection levels.
Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to
exceed $209,002 per violation per day the violation persists, up to a maximum of $2,090,022
for a related series of violations. For violations occurring prior to November 2, 2015, the
maximum penalty may not exceed $200,000 per violation per day, with a maximum penalty
not to exceed $2,000,000 for a related series of violations. We have reviewed the
circumstances and supporting documents involved in this case, and have decided not to
conduct additional enforcement action or penalty assessment proceedings at this time. We
advise you to correct the item(s) identified in this letter. Failure to do so will result in
Dominion Energy Questar Pipeline, LLC being subject to additional enforcement action.
