`
`The United States of America (“United States”), by the authority of the
`
`
`
`
`
`Attorney General of the United States, and on behalf of the United States
`
`Environmental Protection Agency (“EPA”) and the United States Department of
`
`Transportation, Pipeline and Hazardous Materials Safety Administration
`
`(“PHMSA”); and the State of North Dakota (the “State”), on behalf of the North
`
`Dakota Department of Environmental Quality (“NDDEQ”), file this complaint and
`
`allege as follows:
`
`NATURE OF ACTION
`
`1.
`
`This is a civil action against Bridger Pipeline LLC (“Bridger”) and
`
`Belle Fourche Pipeline Company (“Belle Fourche”) (together, “Defendants”).
`
`2.
`
`Defendants own and operate hundreds of miles of buried pipelines
`
`that gather and transport crude oil in Montana, North Dakota, and Wyoming.
`
`3.
`
`On January 17, 2015, one of those pipelines ruptured where it crosses
`
`the Yellowstone River, resulting in the discharge of approximately 1,257 barrels of
`
`crude oil into the Yellowstone River near Glendive, Montana (the “Yellowstone
`
`Spill”), in violation of the Clean Water Act (“CWA”).
`
`4.
`
`In late 2016, another one of those pipelines ruptured in Billings
`
`County, North Dakota, approximately 20 miles northwest of the city of Belfield,
`
`resulting in the discharge of approximately 14,400 barrels of crude oil, including
`
`into an unnamed tributary to Ash Coulee Creek, Ash Coulee Creek itself, the Little
`
`
`
`-2-
`
`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 3 of 51
`
`
`
`Missouri River, and their adjoining shorelines (the “Ash Coulee Spill”), in
`
`violation of the CWA and North Dakota state law.
`
`5.
`
`The United States seeks injunctive relief and civil penalties for
`
`Defendants’ violations of the Clean Water Act and the Federal Pipeline Safety
`
`Regulations pursuant to, respectively, Sections 309 and 311 of the CWA, 33
`
`U.S.C. §§ 1319 and 1321, and Section 60120 of the Pipeline Safety Act (“PSA”),
`
`49 U.S.C. § 60120.
`
`6.
`
`The State seeks injunctive relief and civil penalties for violations of
`
`North Dakota law in connection with the Ash Coulee Spill pursuant to N.D. Cent.
`
`Code §§ 61-28-04(22), 61-28-08, 23-29-04(8), 23-29-11, and 23-29-12. The State
`
`also seeks recovery of its costs relating to the Ash Coulee Spill pursuant to N.D.
`
`Cent. Code §§ 23-31-01 (recodified as 23.1-10-01 in 2019 and then repealed in
`
`2021, 2021 N.D. Sess. Laws, ch. 212, § 19) and 23.1-10-12 (effective 2021).
`
`JURISDICTION AND VENUE
`
`7.
`
`This Court has jurisdiction over the subject matter of this action
`
`pursuant to Sections 309(b), 311(b)(7)(E), and 311(n) of the CWA, 33 U.S.C. §§
`
`1319(b), 1321(b)(7)(E), and 1321(n); Section 60120(a)(1) of the PSA, 49 U.S.C. §
`
`60120(a)(1); and 28 U.S.C. §§ 1331, 1345, and 1355.
`
`8.
`
`This Court has supplemental jurisdiction over the claims asserted by
`
`the State pursuant to 28 U.S.C. § 1367.

`
`Venue is proper in this District pursuant to Sections 309(b) and
`
`311(b)(7)(E) of the CWA, 33 U.S.C. §§ 1319(b) and 1321(b)(7)(E); Section
`
`60120(a)(1) of the PSA, 49 U.S.C. § 60120(a)(1); and 28 U.S.C. §§ 1391 and
`
`1395, because some of the violations that are the subject of this action occurred in
`
`this District, and Defendants are located and do business in this District.
`
`10. Authority to bring the United States’ claims is vested in the United
`
`States Department of Justice by Section 506 of the CWA, 33 U.S.C. § 1366;
`
`Section 60120 of the PSA, 49 U.S.C. § 60120; and 28 U.S.C. §§ 516 and 519.
`
`11. Authority to bring the State’s claims is vested in NDDEQ by N.D.
`
`Cent. Code §§ 61-28-04, 61-28-08, 23-29-04(8), 23-29-11, and 23-29-12. NDDEQ
`
`was established on April 29, 2019, and became the State agency responsible for the
`
`administration and enforcement of the environmental protection programs, laws,
`
`and rules previously administered and enforced by the North Dakota Department
`
`of Health’s Environmental Health Section. Pursuant to 2017 N.D. Laws ch. 199, §
`
`1, the North Dakota Department of Health’s interest in the causes of action alleged
`
`in the Complaint were assigned to NDDEQ. For purpose of the Complaint, the
`
`term “NDDEQ” includes the North Dakota Department of Health for activities
`
`occurring prior to April 29, 2019, and for statutes and rules in effect prior to April
`
`29, 2019. Due to the transition, the statutes in N.D. Cent. Code ch. 23-29 have
`
`moved to N.D. Cent. Code ch. 23.1-08, and the rules in N.D. Admin. Code arts.

`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 5 of 51
`
`
`
`33-16 and 33-20 have moved to 33.1-16 and 33.1-20. Because the violations began
`
`prior to April 29, 2019, NDDEQ references N.D. Cent. Code ch. 23-29 and N.D.
`
`Admin. Code arts. 33-16 and 33-20 in this Complaint, but for activities ongoing
`
`after the transition, NDDEQ also alleges violations of the nearly identical statutes
`
`in N.D. Cent. Code ch. 23.1-08 and rules in N.D. Admin. Code arts. 33.1-16 and
`
`33.1-20.
`
`12. Notice of commencement of this action has been provided to the
`
`States of Montana and North Dakota in accordance with Section 309(b) of the
`
`CWA, 33 U.S.C. § 1319(b).
`
`DEFENDANTS
`
`13. Bridger is a Wyoming limited liability company.
`
`14. Bridger owns and operates the Poplar Pipeline, which gathers and
`

`
`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 6 of 51
`
`
`
`17. Bridger and Belle Fourche are affiliates and under the common
`
`control of the True Companies, a privately held conglomerate with operations
`
`focused on the oil and gas industry.
`
`18. Bridger and Belle Fourche are each a “person” within the meaning of
`
`Sections 311(a)(7) and 502(5) of the CWA, 33 U.S.C. §§ 1321(a)(7) and 1362(5);
`
`Section 60101(a)(17) of the PSA, 49 U.S.C. § 60101(a)(17); and N.D. Cent. Code
`
`§§ 61-28-02(5) and 23-29-03(11).
`
`FEDERAL STATUTORY AND REGULATORY REQUIREMENTS
`
`Clean Water Act
`
`19. Section 301(a) of the Clean Water Act prohibits the discharge of any
`
`pollutant, including oil, by any person, except as authorized by and in compliance
`
`with other sections of the Act. 33 U.S.C. § 1311(a).
`
`20. The Clean Water Act authorizes the United States to “commence a
`
`civil action for appropriate relief, including a permanent or temporary injunction,”
`
`for violations of Section 301 of the Act. 33 U.S.C. § 1319(b).
`
`21. Another section of the Clean Water Act, Section 311(b)(3), prohibits
`
`the discharge of oil into or upon the navigable waters of the United States and
`
`adjoining shorelines in such quantities as the President determines may be harmful
`
`to the public health or welfare or environment of the United States. 33 U.S.C. §
`
`1321(b)(3).
`
`
`
`-6-
`
`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 7 of 51
`
`
`
`22. The President, through a delegation to EPA, has determined that
`
`quantities of oil that may be harmful, for purposes of Section 311, include
`
`discharges that (a) violate applicable water quality standards or (b) cause a film or
`
`sheen upon or discoloration of the surface of the water or adjoining shorelines. 40
`
`C.F.R. § 110.3.
`
`23. Anyone violating Section 311(b)(3) of the CWA, 33 U.S.C. §
`
`1321(b)(3), is subject to a civil penalty. The penalty for a spill in January 2015
`
`(when the Yellowstone Spill occurred) is up to $5,300 per barrel of oil discharged
`
`where the violation was the result of gross negligence or willful misconduct, and
`
`up to $2,100 per barrel in other cases. The penalty for a spill in December 2016
`
`(when the Ash Coulee Spill began) is up to $6,215 per barrel of oil discharged
`
`where the violation was the result of gross negligence or willful misconduct, and
`
`up to $2,072 per barrel in other cases. 33 U.S.C. § 1321(b)(7)(A) and (D); 40
`
`C.F.R. § 19.4.
`
`Federal Pipeline Safety Regulations
`24. Pursuant to Section 60102(a) of the PSA, PHMSA has promulgated
`
`regulations prescribing, among other things, minimum safety standards for pipeline
`
`operation and maintenance. 49 U.S.C. § 60102(a).
`
`25. As relevant here, these regulations are codified at 49 C.F.R. Part 195
`
`(the “Federal Pipeline Safety Regulations”).
`
`
`
`-7-
`
`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 8 of 51
`
`
`
`26. The Federal Pipeline Safety Regulations contain requirements that
`
`apply to operators of hazardous liquid pipelines that could affect a “high
`
`consequence area.” 49 C.F.R. § 195.452.
`
`27. The Federal Pipeline Safety Regulations define “high consequence
`
`area” (“HCA”) to include an “unusually sensitive area.” 49 C.F.R. § 195.450. An
`
`unusually sensitive area, in turn, is defined as “a drinking water or ecological
`
`resource area that is unusually sensitive to environmental damage from a
`
`hazardous liquid pipeline release.” 49 C.F.R. § 195.6.
`
`28. The Federal Pipeline Safety Regulations define drinking water and
`
`ecological resources, for purposes of identifying unusually sensitive areas. A
`
`drinking water resource is defined to include the water intake for a “community
`
`water system” and the “source water protection area” for a community water
`
`system. 49 C.F.R. § 195.6(a). An ecological resource is defined to include an area
`
`containing a critically-imperiled species or an imperiled, threatened, or endangered
`
`species that is aquatic, aquatic dependent, or terrestrial with a limited range. 49
`
`C.F.R. § 195.6(b)(1) and (4).
`
`29. The Federal Pipeline Safety Regulations require operators of pipelines
`
`that could affect a “high consequence area” to develop and implement a written
`
`integrity management program (“IMP”). See 49 C.F.R. § 195.452(b).
`
`
`
`-8-
`
`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 9 of 51
`
`
`
`30. This IMP must assess and address the risks to the integrity of each
`
`segment of pipeline, following “recognized industry practices,” unless otherwise
`
`specified in 49 C.F.R. § 195.452 or the “operator demonstrates that an alternative
`
`practice is supported by a reliable engineering evaluation and provides an
`
`equivalent level of public safety and environmental protection.” 49 C.F.R. §
`
`195.452(b).
`
`31.
`
`In assessing the risks to the integrity of each pipeline segment, the
`
`operator must consider, among other things, “[l]ocal environmental factors that
`
`could affect the pipeline,” such as subsidence (i.e. the gradual caving in or sinking
`
`of an area of land), “geo-technical hazards,” and “[p]otential natural forces
`
`inherent in the area (flood zones, earthquakes, subsidence areas, etc.).” See 49
`
`C.F.R. § 195.452(e) and Appendix C § I.B(12).
`
`32. An operator “must continually change the [IMP] to reflect operating
`
`experience, conclusions drawn from results of the integrity assessments, and other
`
`maintenance and surveillance data.” 49 C.F.R. § 195.452(f). The IMP must
`
`include, among other things, a “continual process of assessment and evaluation to
`
`maintain a pipeline’s integrity,” “[i]dentification of preventative and mitigative
`
`measures to protect the high consequence area,” and a “process for review of
`
`integrity assessment results and information analysis by a person qualified to
`
`evaluate the results and information.” 49 C.F.R. § 195.452(f)(5), (6), and (8).

`
`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 10 of 51
`
`
`
`33.
`
` The operator must also “take measures to prevent and mitigate the
`
`consequences of a pipeline failure that could affect a high consequence area,”
`
`including “conducting a risk analysis of the pipeline segment to identify additional
`
`actions to enhance public safety or environmental protection.” 49 C.F.R. §
`
`195.452(i)(1).
`
`34. The Federal Pipeline Safety Regulations require operators to have a
`
`means to detect leaks on their pipeline systems. 49 C.F.R. § 195.452(i)(3). The
`
`operator “must evaluate the capability of its leak detection means and modify, as
`
`necessary, to protect the high consequence area.” Id.
`
`35. The United States may bring an action to enforce the Federal Pipeline
`
`Safety Regulations. 49 U.S.C. § 60120(a)(1). In such an action, the Court may
`
`award appropriate relief, including a temporary or permanent injunction, punitive
`
`damages, and civil penalties. Id.
`
`STATE STATUTORY AND REGULATORY REQUIREMENTS
`
`Permit Required for Discharges
`
`36. North Dakota Century Code § 61-28-06(2)-(3) makes it unlawful for a
`
`person to discharge any wastes, except in compliance with a valid permit issued by
`
`NDDEQ.
`
`37. North Dakota Administrative Code § 33-16-01-02 provides that a
`
`person must file a NPDES permit application before discharging “any waste
`
`
`
`-10-
`
`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 11 of 51
`
`
`
`through a point source into a surface water.” A NPDES permit issued by NDDEQ
`
`is referred to as a North Dakota pollutant discharge elimination system
`
`(“NDPDES”) permit.
`
`Pollution and Degradation of Water Quality Prohibited
`
`38. North Dakota Century Code § 61-28-06(1)(a) makes it unlawful for a
`
`person “[t]o cause pollution of any waters of the state or to place or cause to be
`
`placed any wastes in a location where they are likely to cause pollution of any
`
`waters of the state.”
`
`39. North Dakota Century Code § 61-28-06(1)(b) makes it unlawful for a
`
`person “[t]o discharge any wastes into any waters of the state or to otherwise cause
`
`pollution, which reduces the quality of such waters below the water quality
`
`standards established therefor by the department.”
`
`40. North Dakota Administrative Code § 33-16-02.1-11(2) makes it
`
`unlawful to discharge into the waters of the state “untreated industrial wastes or
`
`other wastes which contain substances . . . which may endanger public health or
`
`degrade the water quality of water usage.”
`
`41. North Dakota Administrative Code § 33-16-02.1-09 provides for the
`
`classification of the state’s surface water and contains the standards with which the
`
`various classifications of surface water must comply, including physical and
`
`chemical criteria. “[S]treams are classified as the class of water quality which is to
`
`
`
`-11-

`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 12 of 51
`
`
`
`be maintained in the specified stream.” Appendix I, N.D. Admin. Code ch. 33-16-
`
`02.1. At all relevant times, the numeric maximum benzene standard for Class III
`
`streams was 51 µg/l. N.D. Admin. Code § 33-16-02.1-09(3) (2014).
`
`42. North Dakota Administrative Code § 33-16-02.1-08(1) contains the
`
`state’s narrative water quality standards, which, as relevant here:
`
`a.
`
`Require that all waters of the state be free from floating oil or
`
`scum attributable to industrial or other discharges in amounts that are “unsightly or
`
`deleterious”; substances attributable to industrial or other discharges that are in
`
`concentrations or combinations “toxic or harmful to humans, animals, plants, or
`
`resident aquatic biota”; and “oil or grease residue attributable to wastewater, which
`
`causes a visible film or sheen upon the waters or any discoloration of the surface of
`
`adjoining shoreline or causes a sludge or emulsion to be deposited beneath the
`
`surface of the water or upon the adjoining shorelines or prevents classified uses of
`
`such waters.” N.D. Admin. Code § 33-16-02.1-08(1)(a).
`
`b.
`
`Prohibit the discharge of pollutants, which “[c]ause a public
`
`health hazard or injury to environmental resources; [i]mpair existing or reasonable
`
`beneficial uses of the receiving waters; or [d]irectly or indirectly cause
`
`concentrations of pollutants to exceed applicable standards of the receiving
`
`waters.” N.D. Admin. Code § 33-16-02.1-08(1)(e).

`
`43. North Dakota Administrative Code § 33-16-02.1-11(4) provides that
`
`“[a]ny spill or discharge of waste which causes or is likely to cause pollution of
`
`waters of the state must be reported immediately.” The owner, operator, or person
`
`responsible must “provide all relevant information about the spill.” Id. NDDEQ
`
`then has the authority to require the owner or operator to take actions necessary to
`
`comply with N.D. Admin. Code ch. 33-16-02.1, including taking immediate
`
`remedial measures and determining the extent of the pollution. Id.
`
`Unpermitted Disposal and Abandonment of Solid Waste Prohibited
`
`44. North Dakota Century Code § 23-29-07 and North Dakota
`
`Administrative Code § 33-20-02.1-01 makes it unlawful to own, operate, or use an
`
`unpermitted facility for solid waste disposal.
`
`45. North Dakota Administrative Code § 33-20-01.1-04(1) provides
`
`“[a]ny person who owns or operates any premises, business establishment, or
`
`industry is responsible for the solid waste management activities, such as storage,
`
`transportation, resource recovery, or disposal of solid waste generated or managed
`
`at that person’s premises, business establishment, or industry.”
`
`46. North Dakota Administrative Code § 33-20-01.1-04(2) provides “[n]o
`
`solid waste may be delivered to a facility which is not in compliance with this
`
`article or abandoned upon any . . . private premises.”

`
`48. North Dakota Century Code § 23-29-12(1) provides that “[a]ny
`
`person who violates this chapter or any permit condition, rule, order, limitation, or
`
`other applicable requirement implementing this chapter is subject to a civil penalty
`
`not to exceed twelve thousand five hundred dollars per day per violation . . . .”
`
`Injunctive Relief
`
`49. North Dakota Century Code § 61-28-08(5) authorizes NDDEQ to
`

`
`threatened or continuing violation of any provision of this chapter or any permit
`
`condition, rule, order, limitation, or other applicable requirement implementing this
`
`chapter.”
`
`50. North Dakota Century Code § 23-29-11 authorizes NDDEQ to
`
`maintain an action in the name of the state against any person to enjoin actions or
`
`practices that “constitute or will constitute a violation of this chapter, or any rule,
`
`regulation, or order” or for an order directing compliance.

`
`
`Cost Recovery
`
`51. North Dakota Century Code § 23-31-01, which was recodified as
`
`23.1-10-01 in 2019, authorizes NDDEQ to “recover from the parties responsible
`
`for an environmental emergency the reasonable and necessary state costs incurred
`
`in assessment, removal, corrective action, or monitoring as a result of an
`
`environmental emergency in violation of chapter [23-29 or 61-28].”
`
`52. An “environmental emergency” is “a release into the environment of a
`
`substance requiring an immediate response to protect public health or welfare or
`

`
`GENERAL ALLEGATIONS
`
`Poplar Pipeline
`
`56. The Poplar Pipeline is 10 to 12-inches in diameter and approximately
`
`193 miles long. It transports crude oil from the Williston Basin south to Baker,
`
`Montana, where it connects with the Butte Pipeline system.
`
`57. The Poplar Pipeline crosses under the Yellowstone River about six
`
`river miles upstream from the city of Glendive, Montana (the “Yellowstone
`
`Crossing”).
`
`58. The Yellowstone River is the sole source of drinking water for the city
`
`of Glendive.

`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 17 of 51
`
`
`
`59. The reach of the Yellowstone River that includes the Yellowstone
`
`Crossing contains pallid sturgeon, an endangered species of fish that is protected
`
`under the Endangered Species Act of 1973.
`
`60. The Poplar Pipeline has the capacity to transport 42,000 barrels of
`
`crude oil per day. At the Yellowstone Crossing, the line is 12-inches in diameter.
`
`According to Bridger, in the 30 days prior to the Yellowstone Spill, an average of
`
`36,000 barrels of crude oil per day passed through the Poplar Pipeline at the
`
`Yellowstone Crossing.
`
`61. The Yellowstone Crossing was completed in 1967 using the “open-cut
`
`method,” which involves digging a trench across the bottom of the river channel,
`
`laying the pipeline in the trench, and then backfilling the trench with material from
`
`the excavation.
`
`62. The river bottom at the Yellowstone Crossing is comprised of
`
`medium-fine to medium-grained sand alluvium. The alluvium is underlain with
`
`Pierre Shale and easily moved in high flow conditions. The Pierre Shale is
`
`susceptible to river scour (i.e. the erosion of a river bed).
`
`63. At all relevant times, the Poplar Pipeline, at the Yellowstone
`
`Crossing, could affect a High Consequence Area (“HCA”), as that term is defined
`
`in 49 C.F.R. § 195.450.

`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 18 of 51
`
`
`
`64. At the time of the Yellowstone Spill, the Poplar Pipeline, at the
`
`Yellowstone Crossing, was included in the written Integrity Management Plan
`
`developed by Bridger to comply with 49 C.F.R. § 195.452.
`
`65. Bridger has owned and operated the Poplar Pipeline since 2003.
`
`2011 Silvertip Pipeline Spill
`
`66.
`
`In the summer of 2011, the Yellowstone River flooded, scouring the
`
`river bottom and exposing ExxonMobil’s Silvertip Pipeline where it crosses the
`
`Yellowstone River near Laurel, Montana. The exposed pipeline failed in the
`
`currents, resulting in the discharge of more than 1,500 barrels of oil (the “Silvertip
`
`Pipeline spill”).
`
`67. ExxonMobil’s Silvertip Pipeline, like the Poplar Pipeline prior to the
`
`Yellowstone Spill, was installed under the Yellowstone River using the open-cut
`
`method.
`
`68. Following the Silvertip Pipeline spill, PHMSA advised all pipeline
`
`operators, including Bridger, to take steps to prevent and mitigate the risks
`
`associated with flooding and scouring. PHMSA expressly urged operators to
`
`perform surveys to determine the depth of cover at water crossings and to
`
`determine, when floodwaters recede, if flooding has exposed or undermined the
`
`pipeline “as a result of new river channels cut by the flooding or by erosion or
`
`scouring.” 76 Fed. Reg. 44985, 44986 (July 27, 2011).

`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 19 of 51
`
`
`
`69. Bridger was thus on notice no later than July 27, 2011 that flooding
`
`and scouring posed a risk to the integrity of the Poplar Pipeline at the Yellowstone
`
`Crossing.
`
`70.
`
`In September 2011 and April 2012, Bridger conducted depth of cover
`
`surveys at the Yellowstone Crossing. According to these surveys, there were places
`
`where the Poplar Pipeline was less than eight feet below the bottom of the river
`
`channel (i.e. less than eight feet of cover).
`
`71.
`
`In September 2012, the Yellowstone River Conservation District
`
`Council published a report to inform pipeline operators and others about certain
`
`risks to pipelines that cross the Yellowstone River, including “short term scour
`
`during flooding events,” which the report described as “difficult to identify as it is
`
`typically not visible during low flows.” Yellowstone River Pipeline Risk
`
`Assessment and Floodplain Reclamation Planning Project, Final Report,
`
`September 21, 2012 (“Yellowstone Report”) at 1, 7.
`
`72. While the authors of the Yellowstone Report were unable to do a
`
`complete risk assessment, due to a lack of certain information, including channel
`
`geometry, depth of cover, and pipeline configurations, they determined that the
`
`Yellowstone Crossing was at moderate risk of failure due to erodible banklines. Id.
`
`at 26.

`
`
`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 20 of 51
`
`
`
`73. The authors of the Yellowstone Report noted that flood and erosion
`
`controls, including riprap, “can exacerbate the potential for exposure of shallowly
`
`buried pipelines by concentrating erosive forces.” Id. at 52.
`
`74. At the time of the Yellowstone Spill, there was riprap along the left
`
`(west) bank of the Yellowstone River at or near the Yellowstone Crossing.
`
`75. The authors of the Yellowstone Report further noted that the limited
`
`data they had concerning pipeline cover depths “indicates that many of the
`
`pipelines are buried less than eight feet below the channel bottom. These pipelines
`
`are at risk of exposure during flooding events.” Id. at 53.
`
`76. Bridger knew or should have known before the Yellowstone Spill that
`
`the Poplar Pipeline at the Yellowstone Crossing was, in places, buried less than
`
`eight feet below the river bottom.
`
`77. During some winters, the Yellowstone River freezes creating blocks
`
`of ice that form “ice jams.” Ice jams are common on the Yellowstone River,
`
`especially in the vicinity of Glendive, Montana.
`
`78. A March 2014 ice jam event raised the level of the Yellowstone River
`
`by eight feet at Glendive, Montana, resulting in the loss of power to 30 homes and
`
`the evacuation of a trailer park.
`
`79.
`
`Ice jams can both increase the velocity of underwater currents and
`
`shift peak velocity closer to the river bottom, resulting in increased scour potential.

`
`
`
`80. Within several years after the Silvertip Pipeline spill, every other
`
`pipeline operator with a crossing on the Yellowstone River that had been installed
`
`using the open-cut method, except Bridger, implemented measures to address the
`
`risks associated with scouring – either by armoring the crossing with rock or grout
`
`bags or re-installing the pipeline deeper under the river using the horizontal
`
`directional drilling (“HDD”) method. The HDD method, which involves installing
`
`the pipeline through a drilled hole, allows a pipeline to be installed deeper than the
`
`open-cut method, and thereby below the area at risk of scouring.
`
`81. The use of HDD at water crossings is a recognized industry practice
`
`for addressing the risk to the integrity of a pipeline associated with river scour.
`
`82. Unlike all the other operators with crossings on the Yellowstone
`
`River, Bridger failed to take any measures to prevent and mitigate the risks
`
`associated with flooding and river scour at the Yellowstone Crossing, beyond
`
`doing the two depth of cover surveys in 2011 and 2012.
`
`83. Upon information and belief, material information in the 2011 and
`
`2012 depth of cover surveys was false, misleading, or otherwise unreliable and
`
`Bridger either knew or should have known this.
`
`Yellowstone Spill
`
`84. Sometime on or before the morning of January 17, 2015, the Poplar
`
`Pipeline ruptured and began leaking oil at the Yellowstone Crossing.

`Case 1:22-cv-00043-SPW Document 1 Filed 05/02/22 Page 22 of 51
`
`
`
`Impact of Yellowstone Spill
`
`85. As a result of the Yellowstone Spill, oil was discharged into the
`
`Yellowstone River and onto the adjoining shorelines, causing sheens on the river
`
`for miles downstream from the Yellowstone Crossing that lasted for weeks.
`
`86. On January 18, 2015, an oil sheen was observed at the Glendive
`
`municipal water intake, which draws water directly from the Yellowstone River. A
`
`sample taken from Glendive’s municipal water treatment plant contained benzene,
`
`a known human carcinogen, at a level of 14 parts per billion (“ppb”), nearly three
`
`times the maximum contaminant level of 5 ppb. 40 C.F.R. § 141.61(a).
`
`87. On January 18, 2015, Dawson County officials issued a “Do Not
`
`Drink” advisory, and began distributing bottled water to Glendive residents. The
`
`advisory remained in effect until January 23, 2015.
`
`88. On March 14, 2015, after the melting and break-up of winter ice,
`
`operators of Glendive’s water treatment plant detected volatile organic compounds
`
`(“VOCs”) as high as 200 ppb in the Yellowstone River associated with the freeing
`
`up of oil entrained in ice on the river, and again shut down the city’s drinking
`
`water intake.
`
`89. Oil sheens on the Yellowstone River in the vicinity of and as a result
`
`of the Yellowstone Spill were documented until at least April 8, 2015.

`
`
`
`Cause of Yellowstone Spill
`
`90. Following the spill, divers located and retrieved the ruptured pipe
`
`from the bottom of the river and observed that the riverbed covering the pipe had
`
`scoured away, leaving the pipeline unsupported and exposed to river currents.
`
`Once exposed, vortex-induced vibration (“VIV”) and other dynamic loading
`
`caused the pipeline to crack and fail.
`
`91. The use of the open-cut method put the Poplar Pipeline at risk of
`
`failure due to river scour – particularly given the installation of riprap along the left
`
`bank of the river (which can increase river velocity), the frequency of ice jams in
`
`the area of the Yellowstone Crossing, and the geologic formation (Pierre Shale,
`
`which is susceptible to scour).
`
`92. Despite a risk that was known, or should have been known, Bridger
`
`failed to adequately assess the risk of scour at the Yellowstone Crossing, prior t
