92 F.4th 1189
10th Cir.2024Background
- Lazy S Ranch owns a 6,150-acre cattle ranch in Oklahoma, above a major aquifer, with several pipelines (including Valero’s) running underneath it.
- In 2018, a strong diesel/hydrocarbon odor began to be noticed near Tulip Springs, a water feature on the ranch, causing headaches and otherwise deterring use of the area.
- Expert testing revealed trace amounts of refined petroleum products in the ranch's soil, water, and air, though concentrations were mostly below recognized regulatory levels for health risks.
- Lazy S sued Valero alleging the pipeline leaked, asserting claims for negligence, negligence per se, private nuisance, public nuisance, trespass, and other related torts.
- The district court granted summary judgment to Valero on all claims, finding insufficient injury and causation, and denied Lazy S’s motion for reconsideration. Lazy S appealed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Does trace contamination and strong odor constitute actionable injury under Oklahoma law for nuisance/negligence? | Oklahoma law prohibits any contamination; persistent odor and headaches evidenced injury and substantial interference. | Only substantial interference or pollution above statutory thresholds suffices; odors and trace contamination were insubstantial. | Reversed summary judgment: Evidence of strong odors and headaches can create a genuine issue of material fact for nuisance claims. |
| Did Lazy S present sufficient evidence of causation linking Valero’s pipeline to the contamination? | Experts testified Valero’s pipeline was the only plausible source based on recency and type of contaminants. | Other potential contamination sources were present in the area; causation too speculative. | Reversed summary judgment: Competing expert testimony and elimination of other sources create a triable issue on causation. |
| Was summary judgment appropriate given Lazy S’s request for further discovery on Valero’s pipeline monitoring? | Discovery was outstanding and may have shown evidence of leaks; decision was premature. | Plaintiff failed to properly invoke Rule 56(d) (no affidavit/declaration); no basis to delay ruling. | Affirmed summary judgment: Lazy S did not properly comply with requirements for further discovery. |
| Were Lazy S’s remaining tort claims (trespass, constructive fraud, unjust enrichment) properly dismissed? | Valero's conduct amounted to trespass and constructive fraud regarding the leak. | No evidence of intentional trespass or fraud; adequate remedy at law precludes unjust enrichment. | Affirmed summary judgment on these claims: Insufficient evidence of intent or misrepresentation; adequate legal remedy exists. |
