FINAL ORDER
On March 8, 2022, pursuant to 49 C.F.R. § 190.207(c), the Director, Southwest Region, Office
of Pipeline Safety (OPS), issued an Amended Notice of Probable Violation (Amended Notice) to
ONEOK NGL Pipeline, LLC (ONEOK) (Respondent). The Amended Notice proposed finding
that Respondent violated the pipeline safety regulations in 49 C.F.R. part 195 and proposed a
civil penalty of $131,800. The Amended Notice also proposed certain measures to correct the
violations. Respondent did not contest the allegations of violation or corrective measures and
paid the proposed civil penalty on April 7, 2022. In accordance with § 190.208(a)(1), such
payment authorizes the entry of this final order.
Based upon a review of all of the evidence, pursuant to § 190.213, I find Respondent violated the
pipeline safety regulations listed below, as more fully described in the enclosed Amended
Notice, which is incorporated by reference:
49 C.F.R. § 195.52(a)(2) (Item 1) ─ Respondent failed to notify the National
Response Center at the earliest practicable moment following discovery of a
release of hazardous liquid resulting in a fire or explosion not intentionally set by
the operator, but no later than one hour after confirmed discovery of a reportable
accident.
49 C.F.R. § 195.402(c)(11) (Item 2) ─ Respondent failed to have procedures for
utilizing and installing mud plugs as vapor barriers to minimize the likelihood of
accidental ignition of vapors; and failed to prepare and follow written procedures
for monitoring the lower explosive limit of flammable vapors to minimize the
likelihood of accidental ignition in areas near facilities.
49 C.F.R. § 195.402(c)(13) (Item 3) ─ Respondent failed to periodically review
the work done by its personnel to determine the effectiveness of its procedures for



CPF No. 4-2021-048-NOPV
Page 2
minimizing the potential for hazards where the potential exists for the presence of
flammable liquids or gases.
These findings of violation will be considered prior offenses in any subsequent enforcement
action taken against Respondent. In accordance with 49 C.F.R. § 190.223, Respondent is
assessed the proposed civil penalty amount of $131,800, which Respondent has already paid in
full.
Compliance Actions
Pursuant to 49 U.S.C. § 60118(b) and 49 C.F.R. § 190.217, Respondent is ordered to take the
actions proposed in the enclosed Notice to correct the violations. The Director may grant an
extension of time to comply with any of the required items upon a written request timely
submitted by the Respondent and demonstrating good cause for an extension. Upon completion
of ordered actions, Respondent may request that the Director close the case. Failure to comply
with this Order may result in the assessment of civil penalties under 49 C.F.R. § 190.223 or in
referral to the Attorney General for appropriate relief in a district court of the United States.
The terms and conditions of this order are effective upon service in accordance with 49 C.F.R.
§ 190.5.

STATEMENT OF ISSUES
OF
ONEOK NGL PIPELINE, L.L.C.
TO
NOTICE OF PROBABLE VIOLATION,
PROPOSED CIVIL PENALTY,
AND
PROPOSED COMPLIANCE ORDER
ONEOK NGL Pipeline, L.L.C. (“Respondent”) submits this Statement of Issues pursuant to 49
C.F.R. § 190.211(b) in connection with its request for a hearing pursuant to 49 C.F.R. §
190.208(a)(4) and (b)(4).
By letter dated November 15, 2021, the Pipeline and Hazardous Materials Safety Administration
(“PHMSA”) issued to Respondent a Notice of Probable Violation, Proposed Civil Penalty, and
Proposed Compliance Order (collectively, the “NOPV”), CPF No. 4-2021-048-NOPV, which
was received by Respondent via email on the same date. By letter dated December 1, 2021, the
Director, PHMSA Southwest Region, granted an extension of time to respond to the NOPV for
an additional 30 days, until January 14, 2022. By letter of even date herewith, Respondent has
requested a hearing in this matter, and this Statement of Issues is served therewith.
BACKGROUND
The subject NOPV relates to the investigation related to an accident which occurred on April 28,
2020, at Respondent’s Eastlake II Pump Station in Eastland County, Texas.
In the NOPV, PHMSA alleges three violations of the pipeline safety regulations promulgated at
49 C.F.R. Part 195, proposes to assess civil penalties in connection with all three of the said
alleged violations, and proposes to issue a compliance order in connection with two of the said
alleged violations, all pursuant to the procedural and enforcement regulations promulgated at 49
C.F.R. Part 190, Subparts A and B. As to such alleged violations, proposed civil penalties and
proposed compliance orders, Respondent herein states its issues.
Respondent’s Statement of Issues
CPF 4-2021-048-NOPV
Page 1



THE ALLEGED VIOLATIONS
Respondent states below its factual, legal and/or regulatory issues that relate to the alleged
violations of the NOPV. The numbered paragraphs below correspond with the numbered Items
of the NOPV. Each numbered paragraph begins with a citation to the subject regulation and a
summary of the agency’s allegations.
1. 49 C.F.R. § 195.52 (b) – Immediate notice of certain accidents.
PHMSA alleges that Respondent failed to notify the National Response Center (NRC) at the
earliest practicable moment, following discovery of a release of hazardous liquid resulting in a
fire or explosion not intentionally set by the operator, but no later than one hour of “a reportable
accidence as defined in § 195.50.” PHMSA further alleges that Response experienced an
unintentional release of hazardous liquid which resulted in a flash fire as its Eastland II Pump
Station in Eastland County, Texas, on April 28, 2020 at 5:00 p.m. CST. PHMSA finally alleges
that Respondent did not report the accident to the NRC until May 1, 2020, at 11:22 p.m. CDT.
Respondent does not dispute the allegations stated in the NOPV.
2. 49 C.F.R. § 195.402(c)(11) – Procedural manual for operations, maintenance, and
emergencies.
PHMSA alleges that Respondent “failed to develop and follow written procedures for tie-in work
on its pipeline facilities to include the use of mud plugs and monitoring for the lower explosive
limit (LEL),
” which PHMSA claims “are both necessary to maintain safety during normal
operation and maintenance activities.” PHMSA specifically alleges that Respondent failed to
have procedures “for utilizing and installing mud plugs as vapor barriers to minimize the
likelihood of accidental ignition of vapors as required by § 195.402(c)(11).” PHMSA further
alleges that, on April 28, 2020, Respondent’s contractor personnel performed tie-in work using a
mud plug as a vapor barrier and further alleges that Respondent has no written procedures in its
operations and maintenance manual “reflecting the use of mud plugs as a vapor barrier during
tie-in work.”
PHMSA further alleges that Respondent “failed to prepare and follow written procedures for
monitoring LEL of flammable vapors to minimize the likelihood of accidental ignition in areas
near facilities identified under paragraph § 195.402(c)(11).” PHMSA specifically alleges that
Respondent did not establish procedures for monitoring LEL which PHMSA alleges is an action
necessary to minimize the likelihood of accidental ignition of vapors.
PHMSA finally alleges that the lack of written procedures, regarding the use of mud plugs and
the monitoring of the LEL for operator personnel to follow during tie-in work, resulted in the
accident.
Respondent disputes and objects to the allegations stated in the NOPV, on the following
grounds:
Respondent’s Statement of Issues
CPF 4-2021-048-NOPV
Page 2



a. PHMSA has failed to meet its burden of proof that a violation occurred.
b. The alleged violation is not supported by the evidence in the case file.
c. The alleged violation is not supported by the relevant facts.
d. The NOPV fails to adequately make factual findings or to explain, discuss, or
analyze the conclusion that Respondent is in violation of the subject regulation in
the manner alleged.
e. The NOPV fails to explain its conclusions in a manner that is sufficient to allow
Respondent a reasonable opportunity to prepare an adequate defense.
f. Given the manner in which the cited regulation is being applied in this alleged
violation, PHMSA has failed to provide Respondent, or the regulated community
as a whole, fair notice of the agency’s interpretation of the subject regulation.
g. PHMSA has failed to provide a rational connection between the facts alleged and
the conclusions reached, and, as such, the agency is acting in an arbitrary and
capricious manner.
h. The content of the PHMSA case file provided to Respondent fails to fulfill the
requirements of Section 108 of the Protecting Our Infrastructure of Pipelines and
Enhancing Safety Act of 2020; as a result, Respondent is precluded from access to
all relevant facts in the agency’s possession and thus is denied a full and fair
opportunity to respond to the agency’s allegations.
3. 49 C.F.R. § 195.402(c)(13) – Procedural manual for operations, maintenance, and
emergencies.
PHMSA alleges that Respondent failed to periodically review the work of operator personnel to
determine the effectiveness of its procedures and alleges that Respondent did not take
appropriate corrective actions for found deficiencies. Specifically, PHMSA alleges that
Respondent failed to periodically review the work of its personnel “to determine the
effectiveness of its procedures for minimizing the potential for hazards where the potential exists
for the presence of flammable liquids or gases.”
PHMSA alleges that Respondent stated, during the investigation, that it had performed the
periodic review of its procedures to determine their effectiveness and no deficiencies were
identified. PHMSA further alleges that it identified a history of reportable accidents prior to the
April 28, 2020 accident which involved accidental ignition of vapors, and, thus, that
Respondent’s procedure was deficient.
PHMSA finally alleges that, following PHMSA’s investigation, Respondent revised its
procedure to address certain deficiencies.
Respondent disputes and objects to the allegations stated in the NOPV, on the following
grounds:
a. PHMSA has failed to meet its burden of proof that a violation occurred.
b. The alleged violation is not supported by the evidence in the case file.
Respondent’s Statement of Issues
CPF 4-2021-048-NOPV
Page 3



c. The alleged violation is not supported by the relevant facts.
d. The NOPV fails to adequately make factual findings or to explain, discuss, or
analyze the conclusion that Respondent is in violation of the subject regulation in
the manner alleged.
e. The NOPV fails to explain its conclusions in a manner that is sufficient to allow
Respondent a reasonable opportunity to prepare an adequate defense.
f. Given the manner in which the cited regulation is being applied in this alleged
violation, PHMSA has failed to provide Respondent, or the regulated community
as a whole, fair notice of the agency’s interpretation of the subject regulation.
g. PHMSA has failed to provide a rational connection between the facts alleged and
the conclusions reached, and, as such, the agency is acting in an arbitrary and
capricious manner.
h. PHMSA erroneously supports its allegations with evidence of subsequent
remedial measures taken by Respondent.
i. The content of the PHMSA case file provided to Respondent fails to fulfill the
requirements of Section 108 of the Protecting Our Infrastructure of Pipelines and
Enhancing Safety Act of 2020; as a result, Respondent is precluded from access to
all relevant facts in the agency’s possession and thus is denied a full and fair
opportunity to respond to the agency’s allegations.
THE PROPOSED CIVIL PENALTIES
PHMSA proposes a total of $495,047 in civil penalties in connection with alleged violations
Item 2 and Item 3, as to each of which Respondent states the following issues:
1. PHMSA has failed to make available to Respondent or to the public, as required by the
Administrative Procedure Act, fair notice of the methods and procedures by which PHMSA
determines the amount of proposed civil penalties and the amounts eventually assessed.
2. The NOPV and the underlying Pipeline Safety Violation Report fail to establish a sufficient
evidentiary basis for, or adequate discussion, explanation, or analysis of, the penalty
assessment considerations of 49 C.F.R. § 190.225 in support of the proposed civil penalties,
and thus Respondent has no reasonable opportunity to prepare an adequate defense to contest
the proposed civil penalties.
3. Respondent objects to the magnitude of the proposed penalties as: unreasonable;
disproportional to any of the penalty assessment considerations of 49 C.F.R. § 190.225;
unsupported by sufficient evidence or any analysis that applies the penalty assessment
considerations; arbitrary, capricious, or otherwise not in accordance with law; and an abuse
of discretion.
4. To the extent that the related alleged violation is not supported by substantial evidence, a
rational connection between facts found and conclusions drawn, regulation, or law, such
proposed civil penalty may not be imposed.
Respondent’s Statement of Issues
CPF 4-2021-048-NOPV
Page 4



THE PROPOSED COMPLIANCE ORDER
PHMSA proposes to order Respondent to perform the following actions, as to which Respondent
states the following issues:
1. Regarding the alleged violation in Item 2 of the NOPV, develop detailed procedures for (1)
the use of mud plugs “for the prevention and mitigation of vapors igniting while performing
hot work/tie-ins on its pipeline facilities,
” and (2) “LEL monitoring while performing normal
operation and maintenance for the prevention of accident vapor ignition.
”
a. The record reflects that Respondent had procedures addressing LEL monitoring
on the date of the accident, April 28, 2020.
b. To the extent PHMSA is unable ultimately to prove a violation, or any instance of
alleged violation, this proposed compliance order cannot be imposed and,
therefore, must be withdrawn.
c. PHMSA has neither proffered any evidence, made any factual finding, nor
provided any explanation, discussion or analysis of the manner in which either the
nature of the alleged violations or the public interest warrant issuance of the
proposed compliance order; see 49 C.F.R. § 190.217. On those grounds, the
proposed compliance order must be withdrawn in its entirety for failure to fulfill a
regulatory requirement.
2. Regarding the alleged violation in Item 3 of the NOPV, PHMSA proposes that Respondent
conduct a review of certain portions of its Natural Gas Liquids Operations and Maintenance
Manual to determine whether “further revisions” are required.
a. The proposed compliance order is vague and ambiguous, in that the scope and
extent of directed actions are not discernable. As such, PHMSA is acting in an
arbitrary and capricious manner, and thus the proposed compliance order cannot
be imposed and, therefore, must be withdrawn.
b. To the extent PHMSA is unable ultimately to prove a violation, the proposed
compliance order cannot be imposed and, therefore, must be withdrawn.
c. PHMSA has neither proffered any evidence, made any factual finding, nor
provided any explanation, discussion or analysis of the manner in which the
alleged violations or the public interest warrant issuance of the proposed
compliance order; see 49 C.F.R. § 190.217. On those grounds, this proposed
compliance order must be withdrawn in its entirety for failure to fulfill a
regulatory requirement.
CONCLUSION
At the hearing in this matter, Respondent intends to bring forth evidence in the form of
documents and/or testimony, as well as to examine the evidence, documents and any testimony

presented or introduced by PHMSA. Respondent also will present its arguments in support of
the issues stated heretofore. Respondent reserves the right to amend and
supplement this Statement of Issues at or before the hearing.

AMENDED NOTICE OF PROBABLE VIOLATION,
PROPOSED CIVIL PENALTY,
and
PROPOSED COMPLIANCE ORDER
ELECTRONIC MAIL - RETURN RECEIPT REQUESTED
March 8, 2022
Scott Schingen
Senior Vice President, Operations
ONEOK NGL Pipeline, LLC
100 West Fifth Street
Tulsa, Oklahoma 74103
CPF 4-2021-048-NOPV
Dear Mr. Schingen:
From May 1, 2020 through December 2, 2020, a representative of the Pipeline and Hazardous
Materials Safety Administration (PHMSA), Office of Pipeline Safety, pursuant to Chapter 601 of
49 United States Code (U.S.C.), investigated a reportable accident that occurred on April 28, 2020,
at ONEOK NGL Pipeline, LLC’s (ONEOK) Eastland II Pump Station in Eastland County, Texas.
At approximately 5:00 pm Central Standard Time (CST), an incipient fire occurred while
contractor personnel for ONEOK was performing and completing a tie-in weld at the Eastland II
Pump Station. The fire self-extinguished with no reported injuries or hospitalizations. An
estimated .10 barrels of natural gas liquid was unintentionally released. ONEOK submitted
National Response Center (NRC) Report #1276472 on May 1, 2020, as the initial notification of
the accident.
As a result of the investigation, it is alleged that ONEOK has committed probable violations of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items investigated
and the probable violations are:



2
1. § 195.52 Immediate notice of certain accidents.
(a) Notice requirements. At the earliest practicable moment following discovery, of a
release of the hazardous liquid or carbon dioxide transported resulting in an event
described in § 195.50, but no later than one hour after confirmed discovery, the
operator of the system must give notice, in accordance with paragraph (b) of this
section of any failure that:
(1)…
(2) Resulted in either a fire or explosion not intentionally set by the operator;...
(b) Information required. Each notice required by paragraph (a) of this section must
be made to the National Response Center either by telephone to 800-424-8802 (in
Washington, DC, 202-267-2675) or electronically at http://www.nrc.uscg.mil and must
include the following information: …
ONEOK failed to notify the NRC at the earliest practicable moment following discovery of a
release of hazardous liquid resulting a fire or explosion not intentionally set by the operator,
but no later than one hour of a reportable accident as defined in § 195.50. On April 28, 2020,
at approximately 5:00 pm CST, ONEOK experienced an unintentional release of hazardous
liquid which resulted in a flash fire at its Eastland II Pump Station in Eastland County, Texas.
However, ONEOK did not report the accident to the NRC (#1276472) until May 1, 2020, at
11:22 pm CST, over 67 hours after the accident occurred.
2. § 195.402 Procedural manual for operations, maintenance, and emergencies.
(a) General. Each operator shall prepare and follow for each pipeline system a manual
of written procedures for conducting normal operations and maintenance activities
and handling abnormal operations and emergencies. This manual shall be reviewed
at intervals not exceeding 15 months, but at least once each calendar year, and
appropriate changes made as necessary to insure that the manual is effective. This
manual shall be prepared before initial operations of a pipeline system commence,
and appropriate parts shall be kept at locations where operations and maintenance
activities are conducted.
(b) …
(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)…
(11) Minimizing the likelihood of accidental ignition of vapors in areas near facilities
identified under paragraph (c)(4) of this section where the potential exists for the
presence of flammable liquids or gases.



3
ONEOK failed to develop and follow written procedures for tie-in work on its pipeline
facilities to include the use of mud plugs and monitoring for the lower explosive limit (LEL),
which are both necessary to maintain safety during normal operation and maintenance
activities. Specifically, ONEOK failed to have procedures for utilizing and installing mud
plugs as vapor barriers to minimize the likelihood of accidental ignition of vapors as required
by § 195.402(c)(11). On April 28, 2020, ONEOK’s contractor personnel performed tie-in
work utilizing a mud plug as a vapor barrier; however, there were no written procedures in
ONEOK’s operations and maintenance manual reflecting the use of mud plugs as a vapor
barrier during tie-in work.
Additionally, ONEOK failed to prepare and follow written procedures for monitoring LEL of
flammable vapors to minimize the likelihood of accidental ignition in areas near facilities
identified under paragraph § 195.402(c)(11). ONEOK did not establish monitoring procedures
of the LEL as a necessary action to minimize the likelihood of accidental ignition of vapors.
3. § 195.402 Procedural manual for operations, maintenance, and emergencies.
(a) General. Each operator shall prepare and follow for each pipeline system a
manual of written procedures for conducting normal operations and maintenance
activities and handling abnormal operations and emergencies. This manual shall be
reviewed at intervals not exceeding 15 months, but at least once each calendar year,
and appropriate changes made as necessary to insure that the manual is effective.
This manual shall be prepared before initial operations of a pipeline system
commence, and appropriate parts shall be kept at locations where operations and
maintenance activities are conducted.
(b)…
(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)…
(13) Periodically reviewing the work done by operator personnel to determine the
effectiveness of the procedures used in normal operation and maintenance and taking
corrective action where deficiencies are found.
ONEOK failed to periodically review the work done by operator personnel to determine the
effectiveness of the procedures used in normal operation and maintenance, and to take
appropriate corrective actions for found deficiencies. Specifically, ONEOK failed to
periodically review the work done by its personnel to determine the effectiveness of its
procedures for minimizing the potential for hazards where the potential exists for the presence
of flammable liquids or gases.



4
ONEOK's Natural Gas Liquids Operations and Maintenance Manual, PRC1400.000, Section
3, REV 17, Accidental Ignition, 195.402(c)(11) page 35 states,
"In areas near pipeline facilities
where the potential exists for the presence of flammable liquids or gases, ONEOK will take
steps to minimize the likelihood of accidental ignition of vapors." Although ONEOK stated
during the investigation that it had performed the periodic review of its procedure to determine
its effectiveness and did not identify any deficiencies, PHMSA identified a history of
reportable accidents prior to the April 28, 2020 accident that involved accidental ignition of
vapors prior, which indicated that the procedure was deficient. A review of ONEOK's
previously submitted Form PHMSA F7000.1 Accident Reports identified four previous
accidents that involved an accidental ignition of vapors. These include No. 20150445 at Mt.
Belvieu, Texas on November 5, 2015; No. 20170376 at Chapman Trap Station, Kansas on
October 20, 2017; No. 20180207 at ONEOK Groveton Pump Station, Texas on June 22, 2018;
and No. 20180256 at ONEOK Fairfield Pump Station (Site 541), Texas on June 25, 2018.
Following PHMSA's investigation, ONEOK made revisions to this procedure to address
deficiencies.
