In Re: Methyl Tertiary Butyl Ether Products Liability Litigation

Background

This case is part of a multidistrict litigation concerning groundwater contamination caused by releases of gasoline containing methyl tertiary butyl ether, or MTBE. The Commonwealth of Pennsylvania alleges that dozens of gasoline manufacturers, distributors, and sellers are liable for actual or threatened contamination of Pennsylvania drinking water. Its remaining claim is for negligence under Pennsylvania law.

The Commonwealth sought four categories of past damages at Focus Sites: (1) $1,275,062.25 for Pennsylvania Department of Environmental Protection oversight labor costs; (2) administrative costs paid to ICF International, Inc. for processing claims through the Underground Storage Tank Indemnification Fund, or USTIF; (3) approximately $20 million in USTIF reimbursements for cleanup and other corrective actions at 42 Focus Sites; and (4) damages for the lost interim value and benefits of Pennsylvania’s water resources.

The defendants moved for partial summary judgment. Summary judgment is granted when the evidence shows that no genuine dispute about an important fact requires a trial and that the moving party is entitled to judgment under the law. The court must view the evidence and reasonable inferences in favor of the party opposing the motion, but that party must identify admissible evidence supporting its damages claims.

Rulings on the Four Damages Categories

DEP oversight costs

The defendants argued that the free public services doctrine, also called the municipal cost recovery rule, barred the Commonwealth’s claim as a matter of law. The court rejected that argument, predicting that the Pennsylvania Supreme Court would be unlikely to apply the doctrine to a claim brought by the Commonwealth for costs related to environmental damage.

The court nevertheless granted summary judgment to the defendants on the oversight-cost damages. The Commonwealth’s calculation depended on estimates of the time DEP employees spent at each Focus Site. The Commonwealth had not produced an expert report, affidavits from employees describing their work and time, or records showing the time spent on particular tasks. Its representative who explained the calculation did not have personal knowledge of the oversight work. The court also found the calculation’s methodology too flawed to submit to a jury and concluded that the Commonwealth lacked admissible evidence supporting this category of damages.

USTIF administrative costs

The court denied summary judgment as to the USTIF administrative costs. ICF charged the fund a yearly fee for each open claim, and the Commonwealth presented evidence that MTBE made remediation more difficult and caused claims to remain open longer. The court held that this evidence created a factual dispute about whether MTBE contamination was a substantial factor in causing the administrative costs. The defendants may challenge the Commonwealth’s evidence at trial, including the lack of site-specific analysis, but those arguments did not justify summary judgment.

USTIF corrective-action reimbursements

The court denied summary judgment as to the costs that USTIF reimbursed for corrective actions. The defendants argued that they could not be responsible for all remediation costs because chemicals other than MTBE also contributed to the contamination. The court held that the Commonwealth’s experts had offered evidence from which a jury could find that MTBE substantially contributed to the cleanup costs.

The court also rejected the defendants’ reliance on the crashworthiness doctrine. That doctrine generally concerns injuries caused by defects in motor vehicles and requires proof of what injuries would have occurred with a safer design. The court concluded that the doctrine did not appear applicable to this environmental contamination case. It further held that the Commonwealth had identified gasoline without MTBE as an alternative and had offered enough evidence for a jury to infer MTBE-related damages, even though the evidence did not quantify those costs with complete accuracy.

Loss-of-use costs

The court granted summary judgment to the defendants on the Commonwealth’s claim for the lost value and benefits of contaminated water resources. Determining the lost value of groundwater contaminated by a specific chemical requires specialized knowledge, but the Commonwealth had not provided supporting expert testimony or another factual basis that would allow a jury to calculate the damages without speculation. References to DEP personnel, statutory civil penalties, and separate remediation costs were insufficient and could risk an improper double recovery.

Disposition

The defendants’ March 21, 2025 motion for partial summary judgment was granted in part. It was granted as to DEP oversight costs and loss-of-use costs and denied as to USTIF administrative costs and USTIF reimbursement costs for corrective actions. The opinion also states that the Commonwealth’s motion to strike the defendants’ affirmative defense based on the free public services doctrine was granted.
