Court of Appeals hears whether 1992 settlement bars later environmental cleanup claims

The Washington Court of Appeals, Division III, heard oral argument over whether a 1992 settlement agreement between Union Pacific and United States Fire Insurance Company prevents later government cleanup claims tied to other sites.

At oral argument, counsel for Union Pacific told the three-judge panel the 1990 and 1992 agreements were intended to resolve existing coverage disputes and not to release future governmental cleanup claims at sites that were not part of the earlier Wyoming litigation. "The 1992 agreement's release is expressly limited to claimed or threatened liabilities, past tense, for the environmental pollution at the other sites," counsel for Union Pacific argued, urging a narrow construction under Illinois law for releases that did not clearly express intent to bar future claims.

Counsel for United States Fire Insurance pushed back that the 1992 agreement should be enforced according to its text. "There are two definitions that are key," respondent counsel said, citing the agreements' definitions of "other sites" and "environmental pollution" and characterizing them as broad enough to encompass future or presently unasserted claims at Union Pacific facilities. He urged the court to apply settled contract-construction principles that enforce clear written agreements without reliance on extrinsic evidence.

The panel’s questioning focused on whether the release language must be tied to sites and disputes that existed at the time of the settlement or instead could reach later claims. A judge asked whether a site referenced in contemporaneous correspondence but lacking a governmental order until years later would be barred; appellant’s counsel answered that the Wyoming action and the presence of governmental orders were material to whether a site fell within the scope of the original dispute, and that Illinois authority limits broad releases of claims not contemplated at settlement.

Both sides cited Illinois precedents. Appellant pointed to cases holding that general boilerplate cannot be read to bar future unknown claims absent clear language or surrounding circumstances showing intent to do so. Respondent relied on the principle that clear contract language must be enforced and pointed to multiple provisions in the 1992 agreement—definitions and eight specific clauses, the argument said—that demonstrate an intent to release a broad category of environmental coverage disputes.

Counsel also disputed whether the court may consider extrinsic materials, such as the earlier 1990 agreement and the Wyoming declaratory-judgment proceedings, to interpret the 1992 document. Appellant argued the surrounding circumstances and related provisions (including section 2.1 and paragraph 6.7 of the 1990 agreement) support a narrower reading tied to the Wyoming action; respondent countered that the 1992 agreement is a standalone instrument whose defined terms are dispositive.

The transcript shows both sides highlighted potential practical consequences: respondent warned that a narrow reading would burden courts with a multiplicity of suits across hundreds of sites, while appellant urged strict construction of releases to avoid extinguishing claims that could not have been contemplated at the time of settlement. Counsel for Union Pacific noted an option in the 1990 agreement that allowed US Fire to settle certain claims for $2.5 million, and both sides repeatedly returned to how the agreements define "other sites" and the temporal scope of liabilities covered.

After argument and questioning, Judge Tracy Stobb thanked counsel and announced the case was submitted. The panel said an opinion will be issued at a later date.
