Dry Cleaner cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1981. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Rainbow Cleaners has operated as a dry cleaning facility at this Woodinville location since 1981 or 1982, using perchloroethylene (PCE) throughout its history. Investigations confirmed PCE and trichloroethene (TCE) contamination in the subsurface, and cleanup activities have included removal of spilled solvent from a storm drain, containerization and disposal of investigation-derived soil cuttings and decontamination fluids, borehole backfilling, and groundwater purging from monitoring wells. The dry cleaning unit has since been replaced with a PCE-free machine, and ongoing groundwater monitoring is required under the Voluntary Cleanup Program. 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.

Dry cleaning operations using PCE at this site began in 1981, several years before 1986 — the year occurrence-based CGL policies stopped reliably covering pollution claims in Washington. The PCE and TCE contamination documented in soil and groundwater here is characteristic of the slow, diffuse releases those pre-1986 policies were written to address. The documented remediation costs at this site — spill response, subsurface investigation, borehole work, and mandatory long-term groundwater monitoring — represent expenditures that historical carriers whose policies covered this facility during its pre-1986 operational years may be obligated both to recover and to fund going forward.

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.
