Port of Seattle v. The Boeing Company, 2:22-cv-00993

Background

The Lower Duwamish Waterway (LDW) is a Superfund site contaminated by decades of industrial activity; EPA issued a 2014 Record of Decision for cleanup planning.
Since 2000 Boeing, the Port of Seattle, City of Seattle, and King County have been party to an administrative Order on Consent (the LDWG) to investigate and plan remediation, sharing interim costs equally.
In 2013 an ADR process (the Duwamish Allocation) governed by an MOA sought to allocate responsibility among ~45 potentially responsible parties (PRPs); an independent allocator issued a final allocation in 2022.
Boeing accepted its allocated share; the Port rejected its share, withdrew from the Allocation, and filed this suit (CERCLA §107 and related MTCA claims) against Boeing seeking recovery and declaratory relief.
Boeing moved to stay this litigation until April 2023 to allow Participating Parties to complete cash‑out settlement negotiations and EPA consent‑decree negotiations, arguing active litigation would disrupt the settlement process and that settlements would materially reshape or moot issues in this case.
The court granted Boeing’s motion, finding a short stay (until April 30, 2023) unlikely to prejudice the Port materially, likely to prevent disruption of ongoing settlements, and likely to conserve judicial resources; it set deadlines for Boeing’s answer and Rule 26(f) obligations after the stay.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether to stay this case pending completion of the Duwamish Allocation/cash‑out and EPA consent‑decree process	Port: a stay would unduly delay recovery of millions already spent and prolong inequity; litigation should proceed	Boeing: a short stay will permit settlements and consent‑decree negotiations to finish, avoid derailing an eight‑year allocation process, and conserve resources	Court granted a stay until Apr. 30, 2023 to allow settlement/consent‑decree process to proceed.
Whether a stay would harm the Port enough to outweigh other factors	Port: money damages and declaratory relief would be delayed and taxpayers would continue subsidizing cleanup costs	Boeing: delay in money damages is insufficient prejudice; interest and later judgment can compensate; early stage of litigation reduces harm	Court found Port’s prejudice minimal—delay in monetary recovery alone does not preclude a stay.
Whether denying a stay would unfairly prejudice Boeing and the other Participating Parties	Boeing: without a stay it may need to file contribution claims and withdraw from Allocation, likely collapsing settlements and eroding immunity from contribution claims	Port: Boeing can choose not to seek immediate contribution claims and settlements shouldn’t be protected from litigation	Court found Boeing would likely suffer significant hardship and that litigation could disrupt settlements; this supported a stay.
Whether a stay would simplify issues and conserve judicial resources	Port: allocation between Boeing and Port can be decided without other PRPs; settlements won’t affect Port–Boeing equitable allocation	Boeing: finalized allocations and consent decrees would clarify shares, potentially moot contribution issues and simplify equitable allocation	Court agreed settlements would materially aid equitable allocation and conserve resources; factor favors stay.
