Keystone Pipeline CWA settlement proposed: $26,867,789 penalty + $40M work
Federal prosecutors and the U.S. Environmental Protection Agency (EPA) have filed a proposed Clean Water Act settlement aimed at reducing the risk of future oil discharges from the Keystone Pipeline after a Dec. 7, 2022 rupture in Washington County, Kansas.
The case is in its public-comment stage. If the court enters a final order, the companies’ obligations would become enforceable. For now, the next concrete step for the public is the August 14, 2026 comment deadline.
In the DOJ filing announced July 10, 2026, DOJ said South Bow (USA) LP and South Bow Infrastructure Operations Inc. agreed to pay a $26,867,789 civil penalty and complete an estimated $40 million in work to prevent future discharges. DOJ also said the companies would pay the State of Kansas $3 million related to natural resource restoration and alleged state-law violations.
What happened in Kansas
DOJ said the rupture leaked nearly 13,000 barrels (about 543,000 gallons) of oil over land and into Mill Creek. DOJ also described the discharge as blanketing creek areas for about 3.5 miles downstream and said a Kansas stream advisory restricted contact with the creek by people, livestock, and pets.
DOJ further said the spill killed or impacted more than 2,700 animals.
What the government is asking the court to approve
This is not a final judgment. It is a proposed consent decree filed in the U.S. District Court for the District of Kansas. The Federal Register notice also confirms that the publication starts the public comment process, which must run before the court can decide whether to enter a final order.
The proposed decree seeks:
- $26,867,789 in a civil penalty
- Approximately $40 million in injunctive work to strengthen prevention and detection of stress-related failure risk
- Over $3 million for the State of Kansas for natural resource restoration projects and to address related Kansas state-law violations
What “prevention and detection” means in plain English
EPA’s enforcement summary describes the prevention/detection work as steps intended to reduce the likelihood of a similar spill by improving how the operator manages and monitors pipeline integrity risk. Among the categories described:
- Robust procedures, training, and pipeline specifications
- Inspection schedules and operational limits
- Integrity, reliability, and engineering assessments connected to stress/failure prevention and detection
The injunctive relief described by EPA also accounts for corrective actions the companies had already undertaken.
How the public comment window works
EPA’s and DOJ’s announcements, along with the Federal Register notice, show a 30-day comment process. Because the notice was published July 15, 2026, comments are due by August 14, 2026.
After that window closes, the proposed settlement remains subject to court review—so the main “watch next” item is whether the record leads to changes or questions before the court decides on final entry.
Why this matters beyond the Kansas rupture site
Even though the rupture happened in Kansas, the consent decree’s enforceable compliance framework signals how federal regulators are spelling out pipeline integrity, prevention, and monitoring expectations when Clean Water Act discharge risk is alleged.
What to watch next
- Aug. 14, 2026: last day for public comments on the proposed consent decree
- After the comment period: whether the court enters a final order or requests revisions
- If finalized: implementation of the prevention/detection measures (procedures, training, inspection/limits, and integrity/engineering assessments)
