WARNING LETTER
VIA ELECTRONIC MAIL
February 22, 2023
Kenneth Foyil
Vice President of Operations
Hartree Natural Gas Storage, LLC
1 Riverway
Houston, TX 77056
CPF 4-2023-014-WL
Dear Mr. Foyil:
From April 12 to September 26, 2022, a representative of the Pipeline and Hazardous Materials
Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.)
inspected Hartree Natural Gas Storage, LLC’s (Hartree) Pine Prairie Pipeline Header Gas System
in Louisiana.
As a result of the inspection, it is alleged that you have committed probable violations of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items inspected
and the probable violations are:
1. § 192.605 Procedural manual for operations, maintenance, and emergencies.
(a) General. Each operator shall 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.
(b) Maintenance and normal operations. The manual required by
paragraph (a) of this section must include procedures for the following,
if applicable, to provide safety during maintenance and operations.
(1) . . . .
(8) Periodically reviewing the work done by operator personnel to
determine the effectiveness, and adequacy of the procedures used in
normal operation and maintenance and modifying the procedures
when deficiencies are found.



Hartree failed to follow its manual of written procedures for conducting operations and
maintenance activities and for emergency response in accordance with § 192.605(a). Specifically,
Hartree failed to periodically review the work done by operator personnel to determine the
effectiveness, and adequacy of the procedures used in normal operation and maintenance and
modifying the procedures when deficiencies are found as required by § 192.605(b)(8).
Hartree’s procedures state that “Hartree periodically reviews the work done by operator personnel
to determine the effectiveness, and adequacy of the procedures used in normal operation and
maintenance and modifying the procedures when deficiencies are found.”1 However, Hartree
failed to provide records documenting this periodic effectiveness review required by §
192.605(b)(8) and its procedures.
Therefore, Hartree failed to follow its manual of written procedures for conducting operations and
maintenance activities and for emergency response in accordance with § 192.605(a) and §
192.605(b)(8).
2. § 192.605 Procedural manual for operations, maintenance, and emergencies.
(a) . . . .
(d) Safety-related condition reports. The manual required
by paragraph (a) of this section must include instructions enabling
personnel who perform operation and maintenance activities to
recognize conditions that potentially may be safety-related conditions
that are subject to the reporting requirements of § 191.23 of this
subchapter.
Hartree failed to include instructions in its trainings enabling personnel who perform operation
and maintenance activities to recognize conditions that potentially may be safety-related
conditions that are subject to the reporting requirements of § 191.23 in accordance with
§ 192.605(d). Specifically, Hartree failed to provide proper training for its personnel to identify
safety-related conditions.
During the PHMSA inspection, Hartree stated that safety meetings are conducted to train
operations & maintenance personnel on how to recognize conditions that potentially may be
safety-related conditions. However, Hartree failed to provide records of those safety meetings.
Hartree must instruct personnel to recognize safety-related conditions and retain supporting
records.
Therefore, Hartree failed to include instructions in its trainings enabling personnel who perform
operation and maintenance activities to recognize conditions that potentially may be safety-related
conditions that are subject to the reporting requirements of § 191.23 in accordance with
§ 192.605(d).
1 Pipeline Safety Violation Report (Violation Report), (February 22, 2023) (on file with PHMSA), Exh. A, Hartree
Natural Gas Storage, LLC Operations and Maintenance Program (O&M), at section 6.8 (Rev. 1).



3. § 192.705 Transmission lines: Patrolling.
(a) . . . .
(c) Methods of patrolling include walking, driving, flying or other
appropriate means of traversing the right-of-way.
Hartree failed to adequately conduct aerial patrols of its right-of-way (ROW) in accordance with
§ 192.705(c). Specifically, when conducting aerial patrols, Hartree failed to use the correct
mileage to observe surface conditions on and adjacent to the transmission line ROW for indications
of leaks, construction activity, and other factors affecting safety and operation on Pine Prairie’s
Pipeline Header System.
The report forms (Pipeline Patrol/Follow up Report Form No. PPEC 204; 9/2009) did not include
the correct mileage on the forms that the pilot uses to conduct aerial patrols. In addition,
observations are called in to Pine Prairie personnel to investigate near misses and excavation
activity. Excavation activity is investigated by Hartree personnel. Therefore, Pine Prairie must
update these forms with the correct mileage (ROW miles or Pipeline miles), as well as notification
of the observation and the date of investigation by individuals.
Therefore, Hartree failed to adequately conduct aerial patrols of its right-of-way (ROW) in
accordance with § 192.705(c).
Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to exceed
$239,142 per violation per day the violation persists, up to a maximum of $2,391,142 for a related
series of violations. For violation occurring on or after May 3, 2021 and before March 21, 2022,
the maximum penalty may not exceed $225,134 per violation per day the violation persists, up to
a maximum of $2,251,334 for a related series of violations. For violation occurring on or after
January 11, 2021 and before May 3, 2021, the maximum penalty may not exceed $222,504 per
violation per day the violation persists, up to a maximum of $2,225,034 for a related series of
violations. For violation occurring on or after July 31, 2019 and before January 11, 2021, the
maximum penalty may not exceed $218,647 per violation per day the violation persists, up to a
maximum of $2,186,465 for a related series of violations. For violation occurring on or after
November 27, 2018 and before July 31, 2019, the maximum penalty may not exceed $213,268 per
violation per day, with a maximum penalty not to exceed $2,132,679. For violation occurring on
or after November 2, 2015 and before November 27, 2018, the maximum penalty may not exceed
$209,002 per violation per day, with a maximum penalty not to exceed $2,090,022.
