Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1961. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Certified Carpet Inc. operated a carpet and drapery cleaning business at this Lake City Way property from 1961 through 1999, with PCE-based drapery cleaning equipment in use from 1970 onward. The site also hosted a gas station from 1949 to 1968, with associated underground storage tanks removed that year and again in 1994. Cleanup under the Voluntary Cleanup Program has included UST removal with soil excavation and bioremediation, operation of a soil vapor extraction system from 2007 to 2013 that removed 14.10 pounds of PCE, and a continuously operating sump and footing drain system providing ongoing groundwater treatment. Proposed future remediation includes in-situ chemical oxidation via potassium permanganate injection and liquid carbon injection to treat residual groundwater contamination. 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.

The Certified Carpet facility began operations in 1961 — a quarter century before 1986 — and the prior gas station tenancy extends that operational history back to 1949. Occurrence-based CGL policies issued to operators across that pre-1986 window carried no effective pollution exclusion, and the contamination at this site traces directly to those years of operation. The documented remediation expenditures — UST removals, soil excavation, six years of vapor extraction, and ongoing groundwater treatment — represent past costs that historical carriers may be obligated to recover; the proposed ISCO and carbon injection campaigns represent future work that those same carriers may be obligated 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.
