Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1984. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Penthouse Drapery occupied the SCC Building at this Rainier Avenue address from 1984 to 1990, operating dry cleaning equipment that used tetrachloroethylene (PCE) as its primary solvent; PCE releases have been documented at the property from as early as 1980. The building dates to 1947 and has been in continuous commercial and industrial use since that time, with gasoline releases from a former underground storage tank system also on record. Cleanup under the Voluntary Cleanup Program centers on Electric Resistive Heating to treat 9,000 cubic yards of contaminated soil and groundwater over 165 days, with a 20-well Soil Vapor Extraction system processing recovered vapors and groundwater through 2,000 pounds of granular activated carbon; enhanced in-situ anaerobic bioremediation is planned as a follow-on if needed, and the full project — including compliance monitoring — is estimated to take one to five years. 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.

PCE contamination at this property first appeared in 1980 — six years before Washington State's occurrence-based Commercial General Liability policies began reliably excluding pollution claims — placing the originating releases squarely in the coverage window when those carriers were on the risk. The costs already documented through the Voluntary Cleanup Program — site investigation, preparation of a detailed cleanup action plan, and mobilization of ERH and SVE infrastructure — are expenditures those historical carriers may be obligated to reimburse. The one-to-five-year treatment program still ahead, including potential bioremediation contingencies and extensive compliance monitoring, represents a separate and ongoing category of costs the same pre-1986 policies may be required to fund.

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.
