The Notice proposed finding that Respondent had violated the pipeline safety regulations in 49 CFR Part 194 and proposed a civil penalty of $ 62,900. Effective May 20, 2025, PHMSA revised its proposed civil penalty calculation policy to use the version of the Civil Penalty Worksheet in effect when the alleged violation occurred. The new policy did not change the proposed civil penalty in this case. The Notice also proposed certain measures to correct the violations. Respondent did not contest the allegations of violation, corrective measures, or proposed civil penalty. 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 Notice, which is incorporated by reference: 49 CFR § 194.7 (Item 1) ─ Respondent failed to provide records demonstrating that its onshore pipeline facilities were operated in accordance with the applicable response plan. This finding of violation will be considered as a prior offense in any subsequent enforcement action taken against Respondent. In accordance with 49 CFR § 190.223, I assess Respondent a total civil penalty of $62,900. Payment of the civil penalty must be made within 20 days of service. Federal regulations (49 CFR § 89.21(b)(3)) require such payment to be made by wire transfer through the Federal Reserve Communications System (Fedwire), to the account of the U.S. Treasury.

As a result of the inspection, it is alleged that Twin Eagle Midstream has probable violations of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The probable violation is as follows: 1. § 194.7 Operating restrictions and interim operating authorization. (a) . . . . (b) An operator must operate its onshore pipeline facilities in accordance with the applicable response plan.#

52025006NOPV_Final Order_10142025_(24-296481)_text.pdf, page 5Twin Eagle Midstream failed to provide records demonstrating the onshore pipeline facilities were operated in accordance with the applicable response plan. Specifically, Twin Eagle Midstream failed to demonstrate compliance in three areas of their response plan. First, Twin Eagle Midstream failed to provide records to demonstrate compliance with the drill program outlined in its Integrated Contingency Plan (ICP) for calendar years 2020 through April 2024. Twin Eagle Midstream’s ICP (prepared November 2015 and revised October 2023) requires conducting multiple drills 1 including annual Oil Pollution Act (OPA) table-top drills, annual Oil Spill Response Organization (OSRO) equipment deployment drills, semi-annual operator owned equipment deployment drills, quarterly Qualified Individual (QI) notifications, and an annual unannounced exercise. Twin Eagle Midstream’s ICP, Section 18.1, states it will conduct exercises in compliance with the National Preparedness for Response Exercise Program (PREP) Guidelines. 2 During the inspection, Twin Eagle Midstream could not produce documentation demonstrating an annual spill management tabletop exercise drill had been conducted for the calendar year of 2023. Previously, the operator was issued a warning letter in 2023 because it failed to conduct an annual spill management tabletop exercise in 2021. 3 In addition, Twin Eagle Midstream could not produce records to demonstrate an annual unannounced exercise was conducted in 2023. Twin Eagle Midstream failed to conduct quarterly Qualified Individuals (QI) drills in from the first quarter of 2020, through the first quarter of 2024, as required by PREP Guidelines and Section 18.1 of the ICP. During inspection, Twin Eagle Midstream staff were not able to articulate the requirements of Midstream’s ICP and were unaware of the term “QI” despite staff members being listed as Qualified Individuals in the ICP.4 In addition, Twin Eagle Midstream failed to conduct a semi-annual equipment deployment exercise since 2020 as required by its ICP. During the inspection, Twin Eagle Midstream staff indicated Midstream maintains spill response equipment onsite at its Douglas, Wyoming facility. Twin Eagle Midstream also maintains a contract with an Oil Spill Response Organization (OSRO). During inspection, Twin Eagle Midstream was unable to provide records to demonstrate semi-annual equipment deployment exercises had been performed from calendar years 2020 through 2023, nor could it produce records to demonstrate annual equipment deployment exercises by their contracted OSRO for the same years, as required by Section 18.1 of Midstream’ s ICP and the PREP guidelines. Therefore, Twin Eagle Midstream failed to comply with § 194.7(b) by not performing annual spill management tabletop exercises, quarterly QI notifications, semi-annual equipment deployment exercises, annual OSRO equipment deployment exercises, and annual unannounced 1 See ICP, Section 18 – Drills. 2 See 49 C.F.R. § 194.107(c)(1)(ix) (requiring operators to include a drill program within their response plan that follows the National Preparedness for Response Exercise Program (PREP) or equivalent guidelines). 3 See CPF 5-2023-007 WL. 4 Littlepage, Robert. “Re: 2022 ER Drill Report” Received by Diana Fehling, 10 June 2024.#
