Crescent Midstream operates an interstate hazardous liquid pipeline system in Louisiana and the Gulf of Mexico. Respondent operates over 900 miles of hazardous liquid pipelines, and its system includes crude oil breakout tanks subject to the requirements of 49 C.F.R. Part 195 (Part 195). At 10:49 a.m. Eastern Daylight Time (EDT)1 on Saturday, July 27, 2024, the National Response Center (NRC) was notified1 that an unknown amount of crude oil was released at approximately 8:00 a.m. in Lafourche Parish, Louisiana. Two additional NRC notifications2 were made by Crescent Midstream on Monday, July 29, 2024, indicating that an estimated 175 barrels (bbl.), and subsequently 852 total bbl., of crude oil had been released from Crescent Midstream’s pipeline facilities in Raceland (the Accident). No fires, injuries, fatalities, or evacuations occurred as a result of the crude oil release. However, it appears water sources, wildlife, and vegetation have been affected. Pursuant to 49 U.S.C. § 60117, PHMSA’s OPS initiated an investigation of the Accident. The preliminary findings of OPS’ ongoing investigation are as follows: 1 NRC Report No. 1406083. 2 NRC Report No.’s 1406243 and 1406258, respectively.#

42024016CAO_Corrective Action Order_0802024_(24-315924)_text.pdf, page 3Preliminary Findings • Crescent Midstream’s hazardous liquid pipeline facilities in the Raceland area are part of its “Bonefish” system which is composed of 12-, 16-, and 20-inch hazardous liquid pipelines (constructed in the 1950s and 1960s), as well as an aboveground crude oil breakout tank (Tank No. 2051). Respondent’s pipeline facilities near Raceland are located within a high consequence area (HCA)3 as defined by Part 195. • Tank No. 2051 was obtained by Crescent Midstream in 2016, and was removed from service beginning on approximately June 6, 2024, for an inspection. It is unclear to PHMSA if Respondent has construction and inspection history records for Tank No. 2051 as required under Part 195 and American Petroleum Institute (API) standards 650 and 653, to establish the out of service inspection interval. • After removing Tank No. 2051 from service for inspection, Crescent Midstream has been utilizing two temporary frac tanks4 (250 bbl. and 500 bbl. capacities, respectively) and a temporary pump unit. The frac tanks were apparently being used for surge relief purposes, in part, do not meet applicable requirements of Part 195, and were not equipped with any liquid level monitoring devices. • As part of Crescent Midstream’s frac tank setup at Raceland Station, a 16-inch PHMSA regulated pipeline was temporarily connected to the two frac tanks through a Flex-Flo valve set at 160 pounds per square inch gauge (psig). The temporary pump was used to re-inject crude oil into the 16-inch pipeline. Respondent also reportedly performed a tightline operation on one of its 16-inch pipelines (Raceland Station to St. James) without any surge relief at Raceland Station. Another separate operation was performed using the lower pressure measurement piping at the Raceland Station to deliver crude oil to Port Allen via the Sentinel Pipeline and using the temporary frac tanks to provide surge relief. • The temporary pump required manual operation and needed to be in operation to pump crude oil from the frac tanks back into the 16-inch pipeline to reduce the liquid level in the frac tanks. According to Crescent Midstream personnel, the pump was disconnected prior to the Accident. • Respondent indicates it was manually checking the crude oil levels on the frac tanks since their recent installation. However, PHMSA is not aware of the existence of any written procedures addressing this monitoring operation at Raceland Station, nor has Respondent presented records to confirm such monitoring was occurring. Additionally, Crescent Midstream has been unable to provide any specifications related to the pressure rating of the hoses connecting the frac tanks, pipeline, and the temporary pump. • According to an EverLine5 control center log entry for June 25, 2024, the Respondent’s 3 See 49 C.F.R. § 195.450. 4 Frac tank are generally large, moveable, metal storage containers used for temporary storage of liquids or other bulk materials. 5 Respondent utilizes EverLine, a third-party control center operator based out of Houston, Texas, as its control room#

42024016CAO_Corrective Action Order_0802024_(24-315924)_text.pdf, page 4third-party control room was verbally informed that the operating pressure on Respondent’s 16-inch pipeline at Raceland Station should not exceed 120 psig. However, beginning on July 26, 2024, at about 5:20 p.m. Central Daylight Time (CDT), there were multiple occasions where logs indicate the pressure on that pipeline exceeded 120 psig. PHMSA is unaware of any documentation, procedures, or specifications addressing the appropriate pressures relative to the temporary arrangement involving the frac tanks and pump. Respondent was unable to provide any written operating procedures or management of change procedures for communications with their third-party control center (EverLine). • On July 27, 2024 (the date of the Accident) Tank No. 2051 was still out of service and the temporary frac tanks were being used as surge relief without liquid level monitoring. The pressure excursions resulted in crude oil from the pipeline flowing into the frac tanks which overflowed with crude oil. • The discharge valve in the impoundment area in which the frac tanks were located was open, and crude oil overflowing the frac tanks left the impoundment area and flowed into an adjacent ditch and eventually into nearby Bayou Lafourche.6 Bayou Lafourche is a water supply for three Louisiana parishes and a city.7 • According to Respondent, at approximately 9:00 a.m. CDT on July 27, 2024, the discharge valve in the impoundment area was closed upon discovery of the crude oil release. The control room was also instructed to shut down the Raceland Station and the pipelines entering and leaving the facility. Respondent has not provided information indicating what steps the control room took to shut down the pipeline. • As a result of the crude oil release, Bayou Lafourche, nearby residents, wildlife, and vegetation have been affected. • Respondent’s pipeline facilities at Raceland Station remain shut down. PHMSA’s investigation is ongoing and the circumstances leading to the release of crude oil has not yet been determined. Determination of Necessity for Corrective Action Order and Right to Hearing Section 60112 authorizes PHMSA to determine that a pipeline facility is or would be hazardous to life, property, or the environment and if there is a likelihood of serious harm, to expeditiously order to the operator of the facility to take necessary corrective action, including suspended or restricted use of the facility, physical inspection, testing, repair, replacement, or other appropriate action. An order issued expeditiously must provide an opportunity for a hearing as soon as practicable after the order is issued. In deciding whether to issue an order, PHMSA must consider the following, if relevant: (1) the characteristics of the pipe and other equipment used in the pipeline facility, including the age, manufacture, physical properties, and method of manufacturing, constructing, or assembling the equipment; (2) the nature of the material the pipeline facility transports, the corrosive and contractor. 6 Bayou Lafourche is an over 100-mile waterway that flows into the Gulf of Mexico. 7 Assumption Parish, Terrebonne Parish, Lafourche Parish, and Thibodeaux (a city located in Lafourche Parish).#

42024016CAO_Corrective Action Order_0802024_(24-315924)_text.pdf, page 5deteriorative qualities of the material, the sequence in which the material are transported, and the pressure required for transporting the material; (3) the aspects of the area in which the pipeline facility is located, including climatic and geologic conditions and soil characteristics; (4) the proximity of the area in which the pipeline facility is located to environmentally sensitive areas; (5) the population density and population and growth patterns of the area in which the pipeline facility is located; (6) any recommendation of the National Transportation Safety Board made under another law; and (7) other factors PHMSA may consider as appropriate. After evaluating the foregoing preliminary findings of fact and having considered the lack of procedures governing the Respondent’s current operations with respect to the temporary frac tanks and related equipment at the Raceland facility; Crescent Midstream’s current pipeline facility and tank arrangement at Raceland Station that appears to be outside of that allowed under relevant PHMSA hazardous liquid pipeline facility regulations; the unknown status of the required records applicable to Tank No. 2051 illustrating its safety; the hazardous nature of the product transported; the proximity of the pipeline facilities to HCAs, drinking water sources, and human populations; the uncertainty as to the cause of the crude oil release; the uncertainty of potential impacts of the Accident to other of Respondent’s pipelines and facilities as presently arranged at Raceland Station; and because the same condition(s),tank, and pipeline facility equipment arrangement that may have caused the crude oil release remain present at Respondent’s Raceland facilities, I find that continued operation of the pipeline without corrective measures is or would be hazardous to life, property, or the environment, and that failure to issue this Order without notice would result in the likelihood of serious harm. Accordingly, under 49 C.F.R. § 190.233(b), this Order mandating immediate corrective action is issued expeditiously without prior notice and opportunity for a hearing. The terms and conditions of this Order are effective upon receipt. Within 10 days of receipt of this Order, Respondent may request a hearing, to be held as soon as practicable, by notifying the Associate Administrator for Pipeline Safety in writing, with a copy to the Director, OPS Southwest Region, PHMSA (Director). If a hearing is requested, it will be held in accordance with 49 C.F.R. § 190.211. After receiving and analyzing additional data in the course of this investigation, PHMSA may identify other corrective measures that need to be taken. Respondent will be notified of any additional measures required and, if appropriate, PHMSA will consider amending this Order. To the extent consistent with safety, Respondent will be afforded notice and an opportunity for a hearing prior to the imposition of any additional corrective measures.
