Settlement Details
South Bow, the Canada-based operator of the Keystone Pipeline system, has entered a proposed consent decree to resolve federal and Kansas state actions stemming from a December 7, 2022 rupture in Washington County, Kansas. The agreement calls for a civil penalty of $26.9 million, an additional $40 million earmarked for integrity-management and safety upgrades, and more than $3 million for Kansas-funded natural-resource restoration. The decree remains subject to a 30-day public comment period and final approval by a U.S. District Court judge.
Background of the Rupture
The Keystone system transports heavy Canadian tar-sand crude to refineries in Illinois, Oklahoma and Texas. The December 2022 incident occurred at a bend installed in 2010, where a girth-weld crack propagated under cyclic pressure and temperature loading, according to the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA). No workers or residents were injured, and public drinking-water supplies were unaffected, but the spill quickly became the largest on-shore crude-pipeline release in the United States in nine years.
Scale of the Spill
- Volume released: sources report nearly 13,000 barrels of heavy crude (? 1.5 million gallons) and one report cites approximately 14,000 barrels.
- Environmental footprint: oil covered Mill Creek bank-to-bank for 3.5 miles, forming an inch-deep sheen and contaminating roughly 35 acres of surrounding habitat.
- Wildlife impact: more than 2,700 animals were harmed or killed; the area also supports the endangered long-eared bat.
- Comparative size: the volume is “nearly enough to fill an Olympic-sized swimming pool.”
Official Responses
The EPA’s enforcement office and the State of Kansas filed the complaint, alleging violations of federal and state clean-water laws. South Bow has stated that it completed environmental remediation in February 2024, conducted over 12,000 miles of pipeline inspections, and performed 400 excavations to assess and repair vulnerable sections. Kansas officials will receive the restoration funds, while the $40 million safety investment will fund integrity-management measures across the Keystone network.
Criticism and Environmental Concerns
Regulators highlighted that the soil beneath the pipe had been improperly compacted and that a 2013 re-excavation failed to replace the affected pipe segment. Environmental groups note that the spill damaged critical prairie and riparian ecosystems and threatened the long-eared bat’s habitat, underscoring broader concerns about the pipeline’s long-term ecological footprint.
Conflicting Figures and Investigation Gaps
- Barrel count: most reports cite “nearly 13,000 barrels,” whereas PHMSA’s final investigation lists “approximately 14,000 barrels.”
- Cause determination: the PHMSA report attributes the failure to a girth-weld crack, but earlier EPA filings focused on soil compaction and pipe-replacement deficiencies. No public data have been released on the long-term effectiveness of the $40 million safety upgrades.
Verbatim Quotes
- “The oil spill blanketed land and water, rendering the waterway lifeless and useless, and requiring extensive cleanup and remediation,” — Jeffrey Hall, U.S. Environmental Protection Agency assistant administrator for its enforcement office
- “The substantial penalty reflects the seriousness of the environmental harm.” — Jeffrey Hall, EPA enforcement office
- “reflects our ongoing commitment to the safe, reliable operation of our pipeline system and to continuously strengthening pipeline integrity.” — Sara Hunter, South Bow spokesperson
- “South Bow said it began its response before official government directives were issued and completed environmental remediation in February 2024.” — South Bow statement
The settlement marks one of the largest financial penalties for a U.S. on-shore crude spill, linking accountability to extensive remediation and future-prevention commitments.
