Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property hosted up to three separate dry-cleaning facilities in its southern portion, with operations tracing back to the 1930s and additional facilities established in 1947 and 1962 — all demolished by 1978. Tetrachloroethylene (PCE) and its degradation products trichloroethylene (TCE) and vinyl chloride (VC) have been confirmed in soil above MTCA cleanup levels. The active cleanup plan calls for excavation of approximately 300 cubic yards of contaminated soil and 14 treated wood piles, soil vapor extraction combined with Electrical Resistance Heating, and in-situ chemical reduction and enhanced reductive dechlorination targeting groundwater, with multi-year monitoring and up to $600,000 in grant fund reimbursement eligibility for past costs. Cleanup work is ongoing. 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 at this property began in the 1930s — more than five decades before 1986 — and continued through multiple tenants and facility expansions until the facilities were demolished in 1978. Occurrence-based Commercial General Liability policies in force across that extended pre-1986 operational window had no effective pollution exclusion and remain enforceable against historical carriers. The documented remediation costs here — soil excavation, electrical resistance heating, reductive dechlorination for groundwater, and long-term monitoring — represent expenditures already accruing and continuing forward that pre-1986 carriers may be obligated both to recover and 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.
