Industrial & Manufacturing cleanup site — Restorical Research
Cosmo Specialty Fibers, Inc.
Cosmopolis, Grays Harbor County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1957. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property in Cosmopolis was constructed in 1957 and operated as a paper-grade sulfite process pulp mill — later converted to a specialty fiber mill — with documented hazardous substance releases reported in 1978, 1979, and 1980, and additional operational releases as recently as 2022 and 2023. Remediation is proceeding through a Remedial Investigation/Feasibility Study, with planned interim actions that include soil and sediment removal, underground storage tank and pipe removal, and groundwater remediation. Ecology has accumulated $35,000 in remediation costs as of March 2025, and the full remediation timeline is projected to be multi-year. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Hazardous substance releases at this site were first reported in 1978, 1979, and 1980 — nearly a decade before 1986, the year occurrence-based CGL policies stopped reliably covering pollution claims in Washington State. The contamination in soil, sediment, and groundwater here is directly tied to decades of pulp and specialty fiber manufacturing that began in 1957, the kind of chronic industrial release those pre-1986 policies were written to address. The cleanup costs the responsible parties now face — a full RI/FS, interim excavation, tank and pipe removal, and groundwater remediation — could plausibly be funded by historical carriers whose occurrence-based policies were in force during the decades of pre-1986 operations at this mill.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
