In response to the Notice, Denbury contested the alleged violation and the accompanying proposed civil penalty and requested a hearing. (Republic responded separately.) Denbury and PHMSA subsequently engaged in good-faith settlement discussions in order to settle the allegations in the Notice as applied to Denbury. As a result of those discussions, Denbury and PHMSA have agreed to a Consent Agreement by which PHMSA withdraws the allegation of violation in the Notice as applied to Denbury, and Denbury will complete certain compliance actions. Accordingly, the Consent Agreement is hereby approved and incorporated by reference into this Consent Order issued pursuant to 49 CFR § 190.219. Denbury is hereby ordered to comply with the terms of the Consent Agreement pursuant to its terms. Pursuant to 49 U.S.C. § 60101, et seq., failure to comply with this Consent Order may result in the assessment of civil penalties as set forth in 49 U.S.C. § 60122 and 49 CFR § 190.223, or in referral to the Attorney General for appropriate relief in a district court of the United States. For recordkeeping purposes and future correspondence, this Consent Agreement and Consent Order will be referred to as CPF No. 4-2025-024-NOPV-1. Neither the Consent Agreement nor this Consent Order withdraw, satisfy, merge, extinguish, or otherwise affect the alleged violation and proposed civil penalty asserted against Republic in the same Notice. Denbury’s performance of its obligations under the Consent Agreement satisfy its individual obligations, but such performance does not release Republic from its potential liability for the same underlying facts or alleged violations. The enforcement proceeding against Republic remains active and is unaffected by this Order.#

As part of the project, Denbury hired Republic Testing Laboratories, LLC (Republic) as a welding contractor. The inspection included visual observation of welding procedure qualifications and welder qualifications at Republic’s facility in La Porte, Texas. On November 2, 2023, Exxon Mobil Corporation (ExxonMobil) acquired Denbury in an all- stock transaction. By letter dated January 17, 2025, the Director, Southwest Region, OPS (Director), issued to Denbury and Republic a Notice of Probable Violation and Proposed Civil Penalty (Notice). In accordance with 49 CFR § 190.207, the Notice alleged both Denbury and Republic violated 49 U.S.C. § 60118(e)(2)(B)(i) and 49 C.F.R. § 190.203(e) and proposed a civil penalty of $2,366,900. On June 4, 2025, Denbury responded to the Notice by submitting a Request for Hearing and Statement of Issues disputing and objecting to the allegations. PHMSA and Denbury subsequently met to discuss the issues raised in the Notice. As a result of those discussions and as explained in more detail below, PHMSA and Denbury agree that settlement of this proceeding by entry into this Consent Agreement (Agreement) is the most appropriate means of resolving the issues raised in the Notice, will avoid further administrative proceedings or litigation, and is in the public interest. Therefore, pursuant to 49 CFR § 190.219(a), without adjudication of any issue of law or fact, and upon consent and agreement, PHMSA and Denbury agree to the following terms and conditions:#

Examples that may prompt the additional communications and training include, but are not limited to, post-inspection reviews, new or revised regulatory requirements, and newly published PHMSA interpretations or advisory bulletins. c. The regulatory compliance personnel receive training on the ExxonMobil Standards of Business Conduct that includes, among other things, the ExxonMobil policies on ethics, harassment, and environmental health and safety. These employees complete an annual compliance statement at the end of each year, which requires each employee to confirm he/she is familiar with/has read the Standards of Business Conduct within the last 12 months. Additionally, there is online Business Practices Review training for new employees and every two years for existing employees, which covers the Standards of Business Conduct. This training takes approximately one hour to complete and was last updated on June 23, 2025. The training is developed internally. An evaluation is provided after the training allowing employees to provide feedback. 16. Within sixty (60) days of the entry of the Consent Order, PHMSA and Denbury will conduct a meeting, in-person or virtually, to discuss the events that took place at Republic’s facility on September 6, 7, 8, and 11, 2023. Attendees at the meeting will include the PHMSA inspectors who were present at the inspection at Republic’s facility, and the Denbury employees who were present at the inspection at Republic’s facility, to the extent still employed by PHMSA and Denbury, respectively. The deadline may be extended, pursuant to the requirements contained in Paragraph 19 below, to accommodate schedules. III. Dispute Resolution 17. The Director and Denbury will informally attempt to resolve any disputes arising under this Agreement, including any decision of the Director under the terms of Section II (Corrective Measures). If Denbury 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, Denbury may submit a written request for a determination resolving the dispute from the Associate Administrator for Pipeline Safety. Such request must be made in writing and provided to the Director, counsel for the Southwest Region, and to the Associate Administrator no later than 10 calendar days from the 15-day deadline for informal resolution referenced in this paragraph. Along with its request, Denbury must provide the Associate Administrator with all information Denbury 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. IV. Enforcement 18. This Agreement is subject to all enforcement authorities available to PHMSA under 49 U.S.C. § 60101, et seq., and 49 CFR Part 190, including administrative civil#
