Dry Cleaner cleanup site — Restorical Research
Western Pacific Cleaners
Olympia, Thurston County

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a dry cleaning facility at a strip mall in west Olympia, with a dry-cleaning machine and a 55-gallon drum of tetrachloroethylene confirmed on-site as recently as 2011; the dry cleaner tenant vacated in 2018. Cleanup activities under the Voluntary Cleanup Program have included excavation and thermal treatment of 340 tons of contaminated soil, operation of an expanded soil vapor extraction system that has removed 142.4 pounds of PCE, in-situ chemical oxidation with granular activated carbon treatment, and ongoing groundwater monitoring since 2016. Remediation is projected to continue into 2025–2026, with dense non-aqueous phase liquid (DNAPL) still likely present in the subsurface. 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.

A subsurface DNAPL plume requiring thermal treatment of 340 tons of soil, an expanded vapor extraction system, and in-situ chemical oxidation does not accumulate from a brief operational history — the scale of contamination at this Olympia strip mall implies PCE releases that began well before 1986. Carriers who issued occurrence-based CGL policies to this facility's dry cleaning operators during those years cannot disclaim coverage on the basis of pollution exclusions that had not yet been written into those forms. With remediation projected through 2025–2026 and DNAPL still present, both the documented costs incurred to date and the cleanup work still ahead may be recoverable from those historical policies.

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.
