CONSENT AGREEMENT
From February 28 to December 7, 2022, a 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 the following Holly Energy Partners –
Operating, L.P. (Holly, HEP, or Respondent) assets: Osage Pipeline Company, LLC in
Oklahoma, and Kansas; El Dorado Tanks in Kansas; and UNEV Pipeline, LLC in Nevada, and
Utah. Holly, through its subsidiaries and joint ventures, provides petroleum product and crude
oil transportation, terminalling, storage, and throughput services to the petroleum industry and
owns and/or operates onshore petroleum product and crude oil pipelines, tankage and terminals
in Colorado, Idaho, Iowa, Kansas, Missouri, Nevada, New Mexico, Oklahoma, Texas, Utah,
Washington, and Wyoming.
As a result of the inspection, the Director, Southwest Region, OPS (Director), issued to
Respondent, by letter dated March 24, 2023, a Notice of Probable Violation, Proposed Civil
Penalty and Proposed Compliance Order (Notice). In accordance with 49 C.F.R. § 190.207, the
Notice proposed finding that Holly violated 49 C.F.R. § 195.583(a) (Item 1), and proposed
ordering Respondent to take certain measures to correct the alleged violation and a civil penalty
of $108,700.
Holly responded to the Notice by letter dated April 17, 2023 (Response). The company
contested the underlying violation, the proposed civil penalty, and the proposed compliance
order.
PHMSA and Respondent (the Parties) subsequently met to discuss the issues raised in the
Response. As a result of those discussions and as explained in more detail below, the Parties
have agreed to a Consent Agreement which revises the compliance order and reduces the penalty
to $86,000.



Having agreed that settlement of this proceeding will avoid further administrative proceedings or
litigation and will serve the public interest by promoting safety and protection of the
environment, pursuant to 49 U.S.C. § 60101, et seq. and 49 C.F.R. Part 190, and upon consent
and agreement, the Parties hereby agree as follows:
I. General Provisions
1. Respondent acknowledges that as the operator of the pipeline facilities subject to
the Notice, Respondent and its referenced pipeline facilities are subject to the jurisdiction of the
Federal pipeline safety laws, 49 U.S.C. § 60101, et seq., and the regulations and administrative
orders issued thereunder. For purposes of this Consent Agreement (Agreement), Respondent
acknowledges that it received proper notice of PHMSA’s action in this proceeding and that the
Notice states claims upon which relief may be granted pursuant to 49 U.S.C. § 60101, et seq.,
and the regulations and orders issued thereunder.
2. After Respondent returns this signed Agreement to PHMSA, the Agency’s
representative will present it to the Associate Administrator for Pipeline Safety, recommending
that the Associate Administrator adopt the terms of this Agreement by issuing an administrative
order (Consent Order) incorporating the terms of this Agreement. The terms of this Agreement
constitute an offer of settlement until accepted by the Associate Administrator. Once accepted,
the Associate Administrator will issue a Consent Order incorporating the terms of this Agreement.
3. Respondent consents to the issuance of the Consent Order, and hereby waives any
further procedural requirements with respect to its issuance. Respondent waives all rights to
contest the adequacy of notice, or the validity of the Consent Order or this Agreement, including
all rights to administrative or judicial hearings or appeals, except for the Dispute Resolution
provisions set forth herein. Respondent agrees to withdraw its request for an administrative
hearing regarding the Notice.
4. This Agreement shall apply to and be binding upon PHMSA and Respondent, its
officers, directors, and employees, and its successors, assigns, or other entities or persons
otherwise bound by law. Respondent agrees to provide a copy of this Agreement and any
incorporated work plans and schedules to all of Respondent’s officers, employees, and agents
whose duties might reasonably include compliance with this Agreement.
5. This Agreement constitutes the final, complete and exclusive agreement and
understanding between the Parties with respect to the settlement embodied in this Agreement.
The Parties acknowledge that there are no representations, agreements or understandings relating
to settlement other than those expressly contained in this Agreement, except that the terms of this
Agreement may be construed by reference to the Notice.
6. Nothing in this Agreement affects or relieves Respondent of its responsibility to
comply with all applicable requirements of the Federal pipeline safety laws, 49 U.S.C. § 60101,
et seq., and the regulations and orders issued thereunder. Nothing in this Agreement alters
PHMSA’s right of access, entry, inspection, and information gathering or PHMSA’s authority to



bring enforcement actions against Respondent pursuant to the Federal pipeline safety laws, the
regulations and orders issued thereunder, or any other provision of Federal or State law.
7. For all transfers of ownership or operating responsibility of Respondent’s pipeline
system referenced herein, Respondent will provide a copy of this Agreement to the prospective
transferee at least 30 days prior to such transfer. Respondent will provide written notice of the
transfer to the Director no later than 60 days after the transfer occurs.
8. This Agreement does not waive or modify any Federal, State, or local laws or
regulations that are applicable to Respondent’s pipeline systems. This Agreement is not a
permit, or a modification of any permit, under any Federal, State, or local laws or regulations.
Respondent remains responsible for achieving and maintaining compliance with all applicable
Federal, State, and local laws, regulations and permits.
9. This Agreement does not create rights in, or grant any cause of action to, any third
party not party to this Agreement. The U.S. Department of Transportation is not liable for any
injuries or damages to persons or property arising from acts or omissions of Respondent or its
officers, employees, or agents carrying out the work required by this Agreement. Respondent
agrees to hold harmless the U.S. Department of Transportation, its officers, employees, agents,
and representatives from any and all causes of action arising from any acts or omissions of
Respondent or its contractors in carrying out any work required by this Agreement.
10. Except as set forth herein, this Agreement does not constitute a finding of
violation of any other federal law or regulation and may not be used in any civil proceeding of
any kind as evidence or proof of any fact, fault or liability, or as evidence of a violation of any
law, rule, regulation, or requirement, except in a proceeding to enforce the provisions of this
Agreement or in future PHMSA enforcement actions.
II. Finding of Violation:
11. Item 1 - 49 C.F.R. § 195.583(a) & (b): The Notice alleged that Holly failed to
inspect each pipeline or portion of the pipeline that is exposed to the atmosphere for evidence of
atmospheric corrosion at least once every 3 calendar years, but with intervals not exceeding 39
months, paying particular attention to pipe under thermal insulation. Specifically, the Notice
alleged that Holly failed at a receiver at HEP’s facilities in El Dorado, Kansas to conduct adequate
atmospheric corrosion control inspections in 2017 and 2020 for corrosion monitoring locations and
failed to remove the thermal insulation to conduct its inspections. Therefore, PHMSA finds that
Holly violated 49 C.F.R. § 195.583(a) & (b).
12. Item 1 will be considered by PHMSA as a prior offense in any future PHMSA
enforcement action taken against Respondent for the five (5)-year period following the Effective
Date of this Agreement.
III. Civil Penalty:
13. Item 1: The Notice proposed assessing a civil penalty in the amount of $108,700
for Item 1. Respondent requested a reduction of the proposed civil penalty and PHMSA agrees



to reduce the civil penalty. With respect to gravity, PHMSA agrees to reduce the penalty
because Holly agreed to ensure that the pipe under thermal insulation is inspected and promptly
remediated. Respondent agrees to pay a reduced civil penalty in the amount of $86,000 for the
violation in Item 1.
14. Respondent shall pay an adjusted civil penalty in the amount of $86,000, pursuant
to the payment instructions at 49 C.F.R. § 190.227(a), to be paid in full no later than 20 days
from the Effective Date of this Agreement.
IV. Compliance Order:
15. Item 1: The Notice proposed certain compliance order actions to address the non-
compliance alleged in the Notice. Respondent contested the Proposed Compliance Order and
suggested alternative corrective measures to resolve the violation. PHMSA agrees with
Respondent’s request to revise the Proposed Compliance Order because it requires Holly to
inspect pipe under thermal insulation and promptly remediate corrosion. As such, Respondent
agrees to undertake the following corrective measures:
a. HEP agrees to complete an insulation survey of its Part 195-regulated
pipeline systems and submit a copy of the survey to the Director within three (3)
months of the Effective Date.
b. Within twelve (12) months following the Effective Date, HEP will (i)
complete the removal of insulation HEP deems unnecessary, (ii) deploy
removable, seasonal insulation where HEP determines it is needed, and (iii) install
Access Plug Flanges (APF) on any remaining permanent insulation pursuant to
HEP’s EP 21-7-1 Atmospheric Corrosion Monitoring, and Mitigation Procedure.
HEP will provide updates to the Director every other month on the progress of
these actions.
c. HEP will remediate any atmospheric corrosion discovered following the
completion of the insulation survey described in paragraph (a) and inform the
Director of all remediations within twelve (12) months of the Effective Date.
d. HEP will conduct a pilot study to determine the feasibility of using certain
screening tools, which may include, but are not limited to, eddy current or guided
wave technology, to locate optimal APF placements on pipe that will remain
permanently insulated after completion of the survey and submit a copy of the
study to the Director within eighteen (18) months of the Effective Date.
e. If HEP determines that using certain screening tools described in paragraph
(d) is feasible and provides actionable data, HEP will incorporate a program based
on the study into its procedures within 60 days of conducting the pilot study and
submit the updated procedures to the Director. HEP will measure the effectiveness
of the pilot program based on whether the tools used can reliably locate corrosion
under insulation. If the tools are ineffective, HEP will locate APFs on the bottom
of insulated pipe segments, where external corrosion generally appears.



f. HEP will utilize its Pipeline Safety Management System to implement the
above corrective measures.
g. The Director may grant an extension of time to comply with any of the
required actions in Section IV upon a written request submitted by HEP
demonstrating good cause for an extension at least 30 days before the applicable
deadline.
V. Enforcement:
16. This Agreement is subject to all enforcement authorities available to PHMSA
under 49 U.S.C. § 60101, et seq., and 49 C.F.R. Part 190, including administrative civil penalties
under 49 U.S.C. § 60122, of up to $257,664 per violation for each day the violation continues and
referral of the case to the Attorney General for judicial enforcement, if PHMSA determines that
Respondent is not complying with the terms of this Agreement in accordance with the
determinations made by the Director, or in accordance with decisions of the Associate
Administrator if resolved pursuant to the Dispute Resolution process herein. The maximum civil
penalty amounts are adjusted annually for inflation. See 49 C.F.R. § 190.223. All work plans and
associated schedules set forth or referenced in Section IV are automatically incorporated into this
Agreement and are enforceable in the same manner.
VI. Review and Approval Process:
17. With respect to any submission under Section IV (Compliance Order) of this
Agreement that requires the approval of the Director, the Director may: (a) approve, in whole or
in part, the submission; (b) approve the submission on specified, reasonable conditions; (c)
disapprove, in whole or in part, the submission; or (d) any combination of the foregoing. If the
Director approves, approves in part, or approves with conditions, Respondent will take all
actions as approved by the Director, subject to Respondent’s right to invoke the dispute
resolution procedures with respect to any conditions the Director identifies. If the Director
disapproves all or any portion of the submission, the Director will provide Respondent a written
notice of the deficiencies. Respondent will correct all deficiencies within the time specified by
the Director and resubmit it for approval.
VII. Dispute Resolution:
18. The Director and Respondent will informally attempt to resolve any disputes
arising under this Agreement, including any decision of the Director under the terms of Section
IV. If Respondent and the Director are unable to informally resolve the dispute within 15
calendar days after the dispute is first raised, in writing, to the Director, Respondent may submit
a written request for a determination resolving the dispute from the Associate Administrator for
Pipeline Safety, PHMSA. Such request must be made in writing and provided to the Director,
counsel for the Southwest Region, and to the Associate Administrator for Pipeline Safety, no
later than 10 calendar days from the 15-day deadline for informal resolution referenced in this
paragraph. Along with its request, Respondent must provide the Associate Administrator with
all information Respondent believes is relevant to the dispute. Decisions of the Associate
Administrator under this paragraph will constitute final agency action. The existence of a



dispute and PHMSA’s consideration of matters placed in dispute will not excuse, toll, or suspend
any term or timeframe for completion of any work to be performed under this Agreement during
the pendency of the dispute resolution process except as agreed by the Director or Associate
Administrator in writing.
VIII. Effective Date:
19. The term “Effective Date,” as used herein, is the date on which the Consent Order
is issued by the Associate Administrator, PHMSA, incorporating the terms of this Agreement.
IX. Recordkeeping and Information Disclosure:
20. Unless otherwise required in this Agreement, Respondent agrees to maintain
records demonstrating compliance with all requirements of this Agreement for a period of at
least five (5) years following completion of all work to be performed. For any reports, plans, or
other deliverables required to be submitted to PHMSA pursuant to this Agreement, Respondent
may assert a claim of business confidentiality or other protections applicable to the release of
information by PHMSA, covering part or all of the information required to be submitted to
PHMSA pursuant to this Agreement in accordance with 49 C.F.R. Part 7. Respondent must
mark the claim of confidentiality in writing on each page, and include a statement specifying the
grounds for each claim of confidentially. PHMSA determines release of any information
submitted pursuant to this Agreement in accordance with 49 C.F.R. Part 7, the Freedom of
Information Act, 5 U.S.C. § 552, DOT and PHMSA policies, and other applicable regulations
and Executive Orders.
X. Modification:
21. The terms of this Agreement may be modified by mutual agreement of the Parties.
Such modifications must be in writing and signed by both parties.
XI. Termination:
22. This Agreement will remain in effect until the Civil Penalty is paid in full and the
Compliance Order in Section IV is satisfied, as determined by the Director. The Agreement
shall not terminate until the Director confirms, in writing, that the Agreement is terminated in
accordance with this paragraph. Nothing in this Agreement prevents Respondent from
completing any of the obligations earlier than the deadlines provided for in this Agreement.



XII. Ratification:
23. The Parties’ undersigned representatives certify that they are fully authorized to
enter into the terms and conditions of this Agreement and to execute and legally bind such party
to this document.
24. The Parties hereby agree to all findings, conditions, and terms of this Agreement.
