A report authored by Greenpeace USA and Waterkeeper Alliance


Summary Results

  • From 2002 to the end of 2017, ETP, Sunoco and their subsidiaries and joint ventures reported 527 hazardous liquids pipeline incidents to federal regulators — approximately one incident from existing facilities every eleven days.
  • Those incidents, reported by the Pipeline Hazardous Material Safety Administration (PHMSA), released a total of 87,273 barrels (3.6 million gallons, or about five-and-a-half Olympic-sized swimming pools) of hazardous liquids, including 66,515 barrels (2.8 million gallons) of crude oil.
  • In addition, state regulatory agencies have documented spills totaling at least 2.4 million gallons of drilling fluids, sediment and industrial waste during the construction of just two ETP pipelines in Michigan, Ohio, Pennsylvania and West Virginia.
  • Crude oil spills made up 408 of the PHMSA incidents, along with 92 refined petroleum product spills and 27 highly-volatile liquid (HVL), flammable or toxic spills.
  • Of the hazardous liquid spills from existing facilities 101 incidents were of 50 barrels or more (2100 gallons, a volume which is considered “significant” by the federal regulator).
  • 67 of the hazardous liquid incidents were reported to have contaminated water, of which 18 incidents contaminated groundwater.
  • These spills caused an estimated $115 million in property damage, and led to 106 Notices of Probable Violations, and $5,675,870 million in penalties from PHMSA alone.
  • The largest spills in the PHMSA database were crude oil spills of 436,000, 361,000, 290,000, 189,000, 153,000, 143,000, 139,000, and 105,000 gallons, and 2 HVL spills of 168,000 and 121,000 gallons.
  • In addition, state agencies and the Federal Energy Regulatory Commission (FERC) have issued over 100 notices of violation and/or non-compliance for the construction of the Rover and Mariner pipelines. In 2017-18 alone, ETP and Sunoco were issued six stop work orders by state agencies and FERC because their construction operations violated permit requirements and/or rules and regulations designed to protect streams, rivers, wetlands, drinking water, historic sites and public safety.
  • The Dakota Access Pipeline (DAPL) and its southern component only began operations in 2017, but have already reported 7 incidents.
  • Assuming the U.S. system-wide rate for significant crude oil spills of 0.001 per year per mile, we estimate that the Bakken Pipeline would suffer 96 significant spills and the Bayou Bridge Pipeline would suffer eight significant spills, during a 50-year nominal lifetime.
  • There is no failsafe way to transport fossil fuels and pipeline spills remain a direct and seemingly unavoidable consequence of oil and gas activity.
  • Rapid transition to renewable energy could dramatically reduce spills from pipelines and pollution of drinking water sources.

Energy Transfer Partners and Sunoco Have a History of Spills from Existing Pipelines

Energy Transfer Partners and its complex network of subsidiaries and joint ventures owns one of the nation’s largest networks of natural gas, crude oil and petroleum products pipelines. Data collected from the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) shows that the ETP family of hazardous liquids pipelines experienced 527 incidents from 2002 to the end of 2017, spilling ~87,000 barrels, and causing an estimated $115 million in property damage.

We have mapped these incidents, spread across numerous states and regions in the U.S. where ETP operates.[1]

Company History and Structure

Energy Transfer Partners, L.P. (ETP) was founded in 1995 by Ray Davis and Kelcy Warren (who is still its current Chairman and CEO) and became a publicly traded partnership in 2004. ETP is in turn controlled by a master limited partnership called Energy Transfer Equity (ETE), of which Warren is also the Chairman.[2]

The company’s national profile was fairly small until the massive grassroots resistance to its Dakota Access Pipeline (DAPL) led by the Standing Rock Sioux Tribe was splashed across the headlines in 2016. That same year, Warren donated $100,000 to Donald Trump’s presidential campaign[3] and later cut a check for $250,000 for Trump’s inauguration.[4] Trump made the approval of DAPL’s final permits one of his administration’s first priorities upon becoming U.S. President.[5]

ETP’s corporate structure is famously complicated.[6] In October 2012, ETP merged with Sunoco, Inc.,[7] a fuel refining, distribution and retail company that had been founded in 1886.[8] Prior to the merger, ETP and ETE were primarily focused on the natural gas sector, and the merger with Sunoco allowed them to diversify into “liquids” pipelines due to Sunoco’s significant crude oil and refined petroleum product assets.[9] Part of this business operated as Sunoco Logistics Partners (SXL) until it fully merged with ETP in April 2017.[10] Sunoco LP (SUN) continues to exist as a downstream distributor of motor fuel.

Currently three of these entities — ETP, ETE and SUN — are publicly traded on the New York Stock Exchange. The company also boasts a number of subsidiaries and joint ventures as part of its “family” which we have attempted to reflect in this report. Including both liquids and natural gas, ETP operates more than 71,000 miles of pipelines in the U.S. — nearly long enough to encircle the earth three times.[11]

Leaky Pipes

The PHMSA database of all U.S. hazardous liquids pipeline incidents from 2002 to present contains 6,102 reported incidents.[12] Of those incidents, 527 were associated with ETP, Sunoco, or one of their subsidiaries or joint ventures[13] — a rate of one incident occurring approximately every eleven days. These 527 incidents released a total of 87,273 barrels of hazardous liquids, of which 66,515 barrels were crude oil, and led to over $115 million in property damages according to PHMSA’s records. Of the total volume spilled, 36,862 barrels (42%) were never recovered by the company. Since 2002, spills from ETP, Sunoco and subsidiaries led to proposed penalties of $5,675,870.[14]

Other reports have noted the company’s poor safety reputation,[15][16] and have analyzed PHMSA data to conclude that ETP and Sunoco’s pipeline network is among the leakiest in the nation.[17][18] In addition, Sunoco’s Pennsylvania refineries were subject to a comprehensive Clean Air Act settlement, that included a $3 million civil penalty and $285 million to install emissions controls.[19]

Figure 1 shows a timeline of the 527 liquids spills, broken down by corporate entity. As can be seen from the figure, several entities in the ETP family have reported significant numbers of hazardous liquids pipeline spills, both before and after the 2012 merger. Sunoco Pipelines LP has reported 337 incidents since 2002. Also included are spills from joint ventures that Sunoco brought into the merger, notably the Mid-Valley Pipeline (76 incidents), the West Texas Gulf Pipeline (46 incidents), and the Wolverine Pipeline (11 incidents). We include all incidents from Sunoco and its subsidiaries and joint ventures in this analysis, both before and after 2012, because Sunoco brought most of the hazardous liquids assets into the merger and remains part of ETP’s current pipeline network.

Energy Transfer has reported 23 hazardous liquids incidents, all occurring after the 2012 merger. The Dakota Access Pipeline (DAPL) and its southern component (ETCO) only began operations in 2017, but have already reported 7 incidents. For full details on the incident analysis, including more information on the subsidiaries and joint ventures that were included, see Appendix A: Research Methods.

The ten largest incidents in this analysis are the following (in chronological order):

  • In January 2005, the Mid-Valley Pipeline (originally constructed in the 1950s[20]) spilled 6,909 barrels (290,000 gallons) of crude oil into the Kentucky and Ohio Rivers, leading to an oil slick 17 miles long and harming hundreds of migratory birds. The federal government later reached a $2.57 million settlement with Sunoco.[21]
  • In November 2005, operator error led to a 10,380 barrel (436,000 gallon) crude oil overflow at Sunoco Pipeline LP’s Darby Creek Tank Farm in Sharon Hill, Pennsylvania. The spilled oil was contained by a dike, and PHMSA later fined Sunoco $150,000.[22]
  • In October 2008, the Mid-Valley Pipeline spilled again, this time releasing 3,650 barrels (153,000 gallons) into “the sanitary sewer system and nearby Gunpowder Creek” in Florence, Kentucky.[23]
  • In June 2009, a portion of the West Texas Gulf Pipeline near Colorado City, Texas caught fire and spilled 3,416 barrels (143,000 gallons) of crude oil. PHMSA later fined Sunoco Pipeline LP $415,000.[24]
  • In August 2009, Sunoco Pipelines spilled 2,500 barrels (105,000 gallons) of crude from a station near Mont Belvieu, Texas. The U.S. EPA eventually reached a $850,000 settlement for Clean Water Act violations related to this spill and a later 2011 spill of 1,742 barrels (73,000 gallons) in Cromwell, Oklahoma.[25]
  • In October 2014, the Mid-Valley Pipeline experienced yet another major incident, spilling 4,509 barrels (189,000 gallons) and contaminating a ten-mile section of Tete Bayou near Mooringsport, Louisiana.[26]
  • In June 2015, a “gasket failure” on the West Texas Gulf Pipeline near Wortham, Texas led to a release of 3,300 barrels (139,000 gallons) of crude that was contained in two retention ponds on company property.
  • In August and September 2016, Sunoco’s Permian II Express pipeline leaked 8,600 barrels (361,000 gallons) near Sweetwater, Texas. The incident led to a Corrective Action Order, and followed a fine from federal regulators for welding violations on the same project.[27]
  • In addition to crude oil spills, ETP pipelines suffered large spills of highly-volatile liquids (HVL)[28] of 2,880 barrels (121,000 gallons) in 2012 near Midland, Texas and 3,992 barrels (168,000 gallons) in 2014 near Ira, Texas.

Further details on other ETP/Sunoco pipeline incidents can be found in a report by Waterkeeper Alliance, including information on worker lawsuits, failure to report problems, and additional significant pipeline incidents in Pennsylvania, Ohio, and Texas.[29]

Although it is not the main focus on this report, PHMSA also maintains data regarding ruptures and leaks from natural gas gathering, transmission and distribution pipelines. ETP and its subsidiaries reported 58 natural gas incidents to PHMSA from 2002 to present. Natural gas pipeline leaks present a different range of risks from hazardous liquids leaks, including the risk of an explosion. Methane leaking from the U.S.’s rapidly growing natural gas infrastructure is also a significant climate change risk.[30]

Dakota Access Pipeline & Bakken Project

The Bakken Pipeline consists of the 1,172 mile, 30-inch diameter Dakota Access Pipeline (DAPL), which runs from the Bakken oil fields in North Dakota to a hub in Patoka, Illinois, and the Energy Transfer Crude Oil Pipeline (ETCO), which runs 743 miles south from Patoka to Nederland, Texas.[31] The DAPL segment was built across Sioux lands designated under the 1851 Fort Laramie Treaty and crosses the Missouri River near Lake Oahe, just north of the Standing Rock Reservation.[32] The project is a joint venture between ETP, MarEn Bakken Company LLC (Enbridge) and Phillips 66, with ETP holding a 38.25% interest.

Violations of Indigenous sovereignty, lack of adequate consultation and threats to water supplies from pipeline spills led Indigenous Water Protectors and their allies to set-up pipeline opposition camps near the river crossing. The organized pipeline opposition and the disproportional response from authorities and private security forces garnered international media attention, leading the Army Corps of Engineers to deny the needed permits in December 2016. However, the Trump Administration approved the permits and DAPL went into operation in June 2017.

Evidence suggests that environmental racism may have played a part in selecting the pipeline route. The 2015 Environmental Assessment discussed an alternate route that was rejected in part due to concerns about contamination of “wellhead sourcewater protection areas” north of Bismarck, North Dakota (a mostly white community).[33] Yet the approval of the route passing near the reservation led the Standing Rock Sioux Tribe to file a lawsuit alleging violations of the National Historic Preservation Act, the Clean Water Act, and the National Environmental Policy Act.[34]

In addition to the risk of pipeline spills into water, the EA identified impacts from horizontal directional drilling (HDD) used to tunnel the pipeline under rivers, including the risk of “inadvertent release of drilling fluid directly or indirectly into the waterbody” — a risk that has been realized during the construction phases of other ETP/Sunoco projects.

Although the pipeline only became fully operational in 2017, DAPL-ETCO has already reported 7 pipeline incidents to PHMSA, of which 4 occurred along the DAPL portion, and the largest of which was a significant 119 barrel (4,998 gallon) spill from the ETCO segment near Dyersburg, Tennessee. A related eighth incident occurred in March 2017 on a DAPL feeder line owned by Caliber Midstream, but is not included in this analysis.[35]

Assuming the U.S. system-wide rate for significant crude oil spills of 0.001 per year per mile, we estimate that the Bakken Pipeline would suffer 96 significant spills during a 50-year nominal lifetime.

Federal Violations and Fines

PHMSA conducts annual inspections to determine whether pipeline operators are in compliance with federal rules designed to protect the public, drinking water sources and ensure safe operation of pipelines and their associated infrastructure. These routine inspections find violations that could lead to a spill or a safety problem. When federal inspectors find serious issues, they issue Notices of Proposed Violations, Proposed Compliance Orders and/or Proposed Civil Penalties. Since 2002, PHMSA has issued Energy Transfer Partners and Sunoco 106 violations and fined them $5,675,870.[36] Their safety violations include:

  • Failures to inspect crossings under waterways, valves and pipeline rights of way.
  • Failures to notify PHMSA of a spill, fire, injuries requiring hospitalization.
  • Failure to repair unsafe pipe for 5 years.
  • Failures to maintain pipeline integrity in high consequence areas.
  • Failure to report unsafe conditions.
  • Failure to do corrosion inspection.
  • Repeated failures to properly notify emergency responders and the public.[37]

Consequences of Pipeline Spills

Depending on their characteristics, oil spills can cause significant acute and chronic impacts on ecosystems ranging over “a range of time scales, from days to years, or even decades for certain spills.”[38] PHMSA collects information on whether pipeline spills have contaminated soil or water resources, impacted wildlife, or occurred in “high-consequence areas” (HCAs) such as population centers or navigable waterways (see Figure 3).

Of the 527 incidents attributed to ETP, Sunoco, their subsidiaries or joint ventures:

  • 67 incidents (12.7%) were reported to have contaminated water resources. Across the entire PHMSA database, 615 incidents (10.0%) contaminated water resources.
  • Of those incidents, 18 incidents (3.4%) were found to contaminate groundwater. Nationally, there were 207 pipeline spills contaminating groundwater (3.4%).
  • And 3 incidents (0.6%) were found to contaminate drinking water resources specifically. Nationally, there were 8 total incidents (0.1%) contaminating drinking water.
  • 275 incidents (52.5%) contaminated soils.
  • 189 incidents occurred in or reached “high consequence areas.”
  • From 2010-present, there were 6 incidents that impacted wildlife. One of these was a spill of 450 barrels in March 2014, from the Mid-Valley Pipeline, that contaminated the Oak Glen Nature Preserve near Colerain, Ohio,[39] closing the preserve and leaving at least 36 animals in need of treatment for contamination.[40]
  • From 2002 to 2009, there were 3 incidents that impacted fish and 2 incidents that impacted birds.

A 2010 editorial from a Philadelphia-area newspaper lamented the consequences of Sunoco’s local safety record and noted that repeated violations “will only be stopped when the nation’s environmental protection laws finally grow some teeth. In the meantime, Delaware County residents must be satisfied with apologies and the prospect of ill health or injury from another industrial disaster.”[41]

Energy Transfer Partners and Sunoco Spills, Fines and Stop Work Orders During Construction

In addition to past spills from existing pipelines, ETP/Sunoco pipeline projects currently under development have been plagued with environmental violations. The construction of the Mariner and Rover pipelines in Michigan, Ohio, Pennsylvania and West Virginia has resulted in over 2.4 million gallons of spills, over 100 notices of violations and other non-compliance issues, and 6 stop work orders. These new pipelines have faced growing resistance from local communities and decision makers concerned about the long history of non-compliance and pollution of drinking water sources, trout streams, wetlands and rivers.


ETP’s Rover Pipeline is a 713-mile natural gas pipeline designed to transport 3.25 billion cubic feet of gas per day from the Utica and Marcellus shale production areas in West Virginia, eastern Ohio, and western Pennsylvania westward through Ohio and into Michigan.[42] In an ominous foreshadowing, ETP started getting into trouble before construction even started. Despite promising to “avoid adverse effects,” ETP destroyed the historic 170-year old Stoneman House in Dennison, Ohio that was eligible for listing in the National List of Historic places. The Federal Energy Regulatory Commission used the demolition of the historically significant site as a basis for denying Rover a blanket construction permit, saying “Rover could not be relied upon to comply with the environmental regulations.”[43]

With that restriction, FERC approved the project in February 2017, and Energy Transfer began an aggressive effort to construct the pipeline as quickly as possible. In its haste, ETP repeatedly contaminated waterways across Michigan, Ohio and West Virginia. One August 2017 analysis concluded that Rover had “racked up more environmental violations than other major interstate natural gas pipelines built in the last two years” – a total of 104 non-compliance incidents while the second highest company only had 26 non-compliance incidents.[44]

By March 2018, after only 13 months of construction, Rover had spilled more than 2.2 million gallons of drilling fluids, industrial waste and/or sediment, amassing more than 100 violations/non-compliance incidents and 4 stop work orders for their failure to comply with environmental regulations designed to protect streams, rivers wetlands, drinking water, historic sites and public safety (see BOX below for a selection of these violations, citations for these incidents are listed in Appendix C).

The Mariner East Project is designed to transport natural gas liquids from the same Utica and Marcellus shale production areas, this time eastward across Pennsylvania, including to the Marcus Hook terminal on the Delaware River.[45] The first phase of the Mariner project began operations in 2014, while Mariner East 2 is scheduled to be completed in 2018. Construction of the pipeline has led to 108 “inadvertent” releases in numerous locations along the route, leading the Pennsylvania DEP to issue more than 40 violations,[46] and several reports of private water wells being impacted by construction activities.[47] Those spills have released a total of at least 200,000 gallons of drilling fluids and other liquids.[48] The Mariner 1 and Mariner 2 pipelines have been shut down twice as a result of spills, violations, sink holes and contamination of drinking water and trout streams.

The Pennsylvania DEP Administrative Order shutting down construction on January 3, 2018 itemized unpermitted and unlawful activities impacting the following trout streams classified as Class A wild trout waters, wild trout (natural reproduction) water, high quality trout stocking and designated as exceptional value waters and/or migratory fishes:

  1. Hay Creek in Berks County
  2. Cacoosing Creek in Berks County
  3. Allegheny Creek in Berks County
  4. Clover Creek in Blair County
  5. Mingo Creek in Washington County
  6. Shaeffer Creek in Dauphin County

The 24-page order also required Sunoco to address the private water wells contaminated in Silver Lake Township “to the satisfaction of the private well owners.” The order concluded by saying:

“Sunoco’s unlawful conduct… demonstrates a lack of ability or intention on the part of Sunoco to comply with the Clean Streams Law, the Dam Safety and Encroachments Act, and the permits issued thereunder. Suspension of the permits… is necessary to correct the egregious and willful violations described herein.”[49]

On February 8, 2018 the Pennsylvania DEP and Sunoco executed a Consent Order and Agreement requiring the payment of a $12.6 million penalty and that Sunoco provide detailed plans to prevent future violations.[50] It was one of the largest fines ever levied by the State of Pennsylvania for violations of environmental laws.

Less than 30 days later, Mariner was shut down again in Pennsylvania due to problems during construction. On March 7, 2018, the Pennsylvania Public Utility Commission (PUC) issued an emergency order shutting down the Mariner 1 pipeline during construction of the adjacent Mariner 2 pipeline.[51] The emergency order said that allowing the continued transport of hazardous liquids through the Mariner 1 pipeline “could have catastrophic results impacting the public.”[52] The PUC estimated the pipeline would be shut down 10-14 days, possibly longer if ETP/Sunoco failed to address serious safety concerns that the pipeline could be “hazardous to life, property and the environment.”[53] Among the safety issues that triggered the rare emergency shut down were the formation of three large sinkholes in a densely populated area defined by PHMSA as a “high consequence area”. One sinkhole was located 300 feet from rail lines carrying Amtrak and Septa passengers. Another sink hole was created 10 feet from the foundation of a house.

Future Threats to Water

Bayou Bridge Pipeline

Oil and pipeline companies have devastated the Gulf coast and the Atchafalaya Basin, harming some of the most amazing ecosystems on Earth, putting millions of people at greater risk of flooding.[64] The Bayou Bridge pipeline is a great example of what is wrong with pipeline construction in Louisiana. It will traverse over, under or through the Calcasieu River, Mermentau River, Vermilion River, Bayou Teche, West Atchafalaya Basin Levee, Atchafalaya River Basin and multiple bayous that provide unique habitat for many rare species. There is pending litigation arguing that the existing corridor being used to place the Bayou Bridge Pipeline is already out-of-compliance with permits issued for prior pipeline projects. In the same litigation, opponents argue that another existing pipeline in the Atchafalaya Basin co-owned by Energy Transfer Partners is also out of compliance with a previously-issued permit.[65] Disposal of dredged material during the construction of these earlier pipelines led to the creation of spoil banks which have been found to cause serious disturbances of water flow and impact the distribution of sediments in the Basin.[66] Historically there has been little enforcement of permit violations.[67]

The Bayou Bridge pipeline is a joint venture between ETP and Phillips 66[68] (two of the participants in DAPL) that will transport up to 480,000 barrels of crude oil a day across Louisiana, from Nederland, Texas (the southern terminus of the Bakken pipeline) to refineries in St. James, Louisiana (about 50 miles up the Mississippi River from New Orleans).[69] Phase I of the Bayou Bridge Pipeline, from Nederland, Texas to Lake Charles, Louisiana, is already operational. However, Phase II, the proposed 163-mile portion from Lake Charles to St. James, is under construction and multiple lawsuits have been filed to challenge the permits issued in 2017.[70]

As detailed in a U.S. Army Corps of Engineers Environmental Assessment, Bayou Bridge Pipeline LLC plans to use horizontal directional drilling (HDD) to run pipe under 8 federal projects and 14 federal easements (mostly crossings of rivers, waterways and levees).[71] As is typical, PHMSA conducted a “worst case” analysis for spills occurring at those crossings, but details of that analysis have not been made public.

Analysis by FracTracker Alliance found that the pipeline would cross “700 acres of fragile wetlands, and watersheds that supply drinking water for up to 300,000 people” and noted that “essential ecosystem services that the wetlands provide, absorbing floodwaters, could be compromised, leading to increased erosion and sedimentation downstream. Impacts to these wetlands could be greatly magnified into the already environmentally stressed Gulf.”[72]

Assuming the U.S. system-wide rate for significant crude oil spills of 0.001 per year per mile, we estimate that the Bayou Bridge Pipeline would suffer eight significant spills during a 50-year nominal lifetime. In February 2018, a federal court issued an injunction stopping construction while the court considers environmental challenges to the project.[73] But that injunction was stayed by the 5th Circuit Court of Appeals in March with an expedited hearing on the injunction appeal scheduled before a merits panel on April 30, 2018.[74]

Bayou Bridge Pipeline began clearing for construction in the Atchafalaya Basin in January 2018.[75] Despite the elevated annual rise of water in the Basin, Bayou Bridge intends to continue construction in the Basin during high water season.[76] Construction during high water could exacerbate the damage to wetlands, channeling sediment-laden water into the interior swamps through pipeline canals, causing increased sedimentation and filling of wetlands which reduce their future capability to protect millions of people from Mississippi River floods.[77]

Permian Express

In late 2017, ETP brought its Permian Express 3 pipeline online, transporting crude oil from the Permian basin (a major oil and gas producing basin located in West Texas and parts of New Mexico) to facilities in Nederland, Texas, and is “aggressively” evaluating a further expansion of that line.[78]
