Carolyn Baker v. Chevron U.S.A. Inc.
533 F. App'x 509
6th Cir.2013Background
- Chevron operated a Hooven, Ohio refinery (1931–1986); releases created an LNAPL plume (~8 million gallons) containing benzene that migrated under part of the Village of Hooven.
- ~200 plaintiffs (neighbors) asserted three types of claims: personal injury from airborne benzene emissions; property damage from groundwater/plume and soil-vapor intrusion; and medical-monitoring damages for increased risk from plume exposures.
- District court selected bellwether plaintiffs, excluded key plaintiff experts (air causation expert Dr. Dahlgren and property expert Dr. Bedient) under Daubert/Rule 26, and granted Chevron summary judgment on all claims.
- District court dismissed medical-monitoring claims for lack of individualized exposure/dose evidence and inadequate, non-specific monitoring plan; later imposed Rule 11 sanctions ($250,000) on plaintiffs’ counsel for continuing meritless medical-monitoring claims.
- On appeal the Sixth Circuit reviewed exclusions for abuse of discretion and summary judgment de novo and affirmed: expert exclusions, summary judgment for Chevron on personal injury and property claims, dismissal of medical-monitoring claims, and Rule 11 sanctions.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of causation expert (personal injury) | Dr. Dahlgren’s reports and testimony show benzene exposures sufficient to cause plaintiffs’ diseases | Dahlgren’s reports violated Rule 26, were untimely/unsupported, lacked dose quantification and differential diagnosis; relied on weak/insignificant studies | Court excluded Dahlgren (Daubert/Rule 26); no admissible causation evidence; summary judgment for Chevron affirmed |
| Property damage: groundwater rights (McNamara) | Plume unreasonably interferes with groundwater rights and zoning/use restrictions | Plaintiffs never used groundwater; Ohio law protects groundwater use, not mere subsurface presence | No groundwater claim under McNamara; plaintiffs lack use-based property right |
| Property damage: indirect subsurface trespass (Chance) | Detection of plume constituents on/near properties suffices as physical damage/interference | Mere detection is insufficient; must show invasion plus substantial physical damage or substantial interference with foreseeable use | Plaintiffs failed to show site-specific invasion or substantial damage/interference; Bedient excluded for lacking vapor-pathway analysis; summary judgment for Chevron affirmed |
| Medical monitoring damages | Community evidence, ODH cancer study, and general monitoring plan justify monitoring for exposed plaintiffs | Must show individualized exposure/dose causing a present, substantial increased risk and a physician would prescribe monitoring; plaintiffs lack individualized dose and disease specificity | Dismissed with prejudice: plaintiffs provided no individualized exposure/dose, no disease-specific risk, and plan was not disease-directed; Rule 11 sanctions affirmed for counsel’s unreasonable litigation of these claims |
