WARNING LETTER
mhurley@expl.com; Kbrown@expl.com
VIA ELECTRONIC MAIL TO: September 13, 2022
Mark Hurley
President and Chief Executive Officer
Explorer Pipeline Co.
P.O. Box 2650
Tulsa, Oklahoma 74136
CPF 3-2022-063-WL
Dear Mr. Hurley:
From June 7 through September 20, 2021, representative of the Pipeline and Hazardous
Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant to Chapter
601 of 49 United States Code (U.S.C.), inspected Explorer Pipeline Co.’s (Explorer) inspection
system in Illinois, Missouri, Oklahoma, and Texas.
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. § 195.402 Procedural manual for operations, maintenance, and emergencies.
(a) . . . .
(c) Maintenance and normal operations. The manual required by paragraph (a) of
this section must include procedures for the following to provide safety during
maintenance and normal operations:
(1) Making construction records, maps, and operating history available as necessary
for safe operation and maintenance.
Explorer failed to maintain current maps and records of its pipeline system as required under
§ 195.402(c)(1). Specifically, Explorer did not have each valve and safety device labeled in the
field. During emergency conditions, it is essential that pipeline valves can be identified quickly
and accurately to facilitate a prompt and effective response to minimize the volume of hazardous
liquid released in the event of failure, per procedures required by § 195.402(e)(4).
During a field visit, the technician was asked about the identification of a particular valve. This
information was not readily available, per procedures required by § 195.402(c)(1).



The information was obtained from drawings online, but there was no service at this location so
the identification of the valve was not able to be given until later in the day. It was noted during
the field inspection that the identification of valves and safety devices were not handled
consistently across the pipeline system. Some were identified by tags or markings on the device,
and others were not. Explorer’s operations and maintenance procedures did not address device
identification on the device itself.
2. § 195.406 Maximum operating pressure.
(a) . . . .
(b) No operator may permit the pressure in a pipeline during surges or other
variations from normal operations to exceed 110 percent of the operating pressure
limit established under paragraph (a) of this section. Each operator must provide
adequate controls and protective equipment to control the pressure within this limit.
Explorer failed to provide adequate controls and protective equipment to control the pressure
within one hundred ten percent (110%) of the operating pressure limit. Explorer’s DOT
Procedure Manual did not include requirements for locations not protected by equipment to
control the pressure within one hundred ten percent (110%) of the operating pressure.
Specifically, Revision 2.4 of the procedures did not address locations, as identified during field
visits, without thermal over pressure protection between valves. Both the procedures and
regulations require adequate controls and protective equipment to control the pressure, which
includes thermal devices in areas that can be shut-in such as between valves. PHMSA would
like some designation on drawings or on the valve to indicate that the valves are, in fact,
normally open.
3. § 195.412 Inspection of rights-of-way and crossings under navigable waters.
(a) Each operator shall, at intervals not exceeding 3 weeks, but at least 26 times each
calendar year, inspect the surface conditions on or adjacent to each pipeline right-
of-way. Methods of inspection include walking, driving, flying or other appropriate
means of traversing the right-of-way.
Explorer failed to maintain the right-of-way (ROW) at an appropriate level for the type of patrols
that were being done. During ROW inspections there were several areas noted by PHMSA as
being overgrown with some areas having tree growth canopied over the pipeline.
Patrolling of rights-of-way is essential to help identify potential problems from third party
activities along the pipeline and for leak detection. The surface conditions of the right-of-way
and adjacent areas cannot be inspected by aerial patrolling if those areas are obstructed by an
overhanging tree canopy.
4. § 195.452 Pipeline integrity management in high consequence areas.
(a) . . . .



(f) What are the elements of an integrity management program? An integrity
management program begins with the initial framework. An operator must
continually change the program to reflect operating experience, conclusions drawn
from results of the integrity assessments, and other maintenance and surveillance
data, and evaluation of consequences of a failure on the high consequence area. An
operator must include, at minimum, each of the following elements in its written
integrity management program:
(1) . . . .
(6) Identification of preventive and mitigative measures to protect the high
consequence area (see paragraph (i) of this section);
(i) What preventive and mitigative measures must an operator take to protect the
high consequence area?
(1) General requirements. An operator must take measures to prevent and mitigate
the consequences of a pipeline failure that could affect a high consequence area.
These measures include conducting a risk analysis of the pipeline segment to
identify additional actions to enhance public safety or environmental protection.
Such actions may include, but are not limited to, implementing damage prevention
best practices, better monitoring of cathodic protection where corrosion is a
concern, establishing shorter inspection intervals, installing EFRDs on the pipeline
segment, modifying the systems that monitor pressure and detect leaks, providing
additional training to personnel on response procedures, conducting drills with local
emergency responders and adopting other management controls.
Explorer failed to establish an adequate procedure for the identification of preventative and
mitigative (P&M) measures that is compliant with § 195.452(f)(6). The current processes,
“Facility Integrity Management Plan,” last revised on 11/30/2021, and “Preventative and
Mitigative Actions to Protect HCAs,” last revised on 11/23/2021, addressed both facilities and
pipelines. These processes did not define time-frames for additional leak detection and
emergency flow restricting device evaluations or state the documentation requirements, in
accordance with § 195.452(l), for each evaluation. Additionally, many of the listed P&M
measures were required per regulations and were not in addition to normal requirements based
upon a risk analysis of that line segment.
5. §195.505 Qualification program.
Each operator shall have and follow a written qualification program. The program
shall include provisions to:
(a) . . . .
(b) Ensure through evaluation that individuals performing covered tasks are
qualified;
Explorer failed to ensure, through evaluation, that an individual performing a covered task was
qualified. The individual who performed the pipeline right-of-way (ROW) foot patrols of Routes
11 and 12 had operator qualifications (OQ’s) that expired on February 15, 2021. Therefore, that
individual had conducted the ROW foot patrols in 2021 with expired OQ’s.
6. §195.583 What must I do to monitor atmospheric corrosion control?
(a) . . . .



(b) During inspections you must give particular attention to pipe at soil-to-air
interfaces, under thermal insulation, under disbonded coatings, at pipe supports, in
splash zones, at deck penetrations, and in spans over water.
Explorer failed to give particular attention to interfaces and splash zones during atmospheric
corrosion inspections. During PHMSA field inspections, it was noted that some valves were
located in vaults filled with water. Personnel typically did not drain the water or remove the
grating to look at the pipe below the grating during the atmospheric surveys. This does not allow
for a thorough inspection of the transition and piping.
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.
