Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

The former Bay City Cleaners dry cleaning operation at this Shoreline property used tetrachloroethylene (PCE) for an extended period before closing and being demolished in 1998. Environmental assessment beginning in 1996 revealed PCE contamination in soil and groundwater, leading to excavation of approximately 400 cubic yards of contaminated soil under the Voluntary Cleanup Program. The property also contained underground storage tanks for gasoline and home heating oil associated with the Park Ridge Care Center, with groundwater monitoring confirming petroleum hydrocarbons (TPH-G, TPH-D), benzene, and ethylene dibromide (EDB) exceeding MTCA Method A cleanup levels at on-site monitoring wells. 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 PCE contamination at this property originated from dry cleaning operations that ran for an indeterminate period before the facility's 1998 demolition — a timeline consistent with decades of pre-1986 use, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The scale of remediation here — 400 cubic yards of soil excavation and groundwater treatment extending from 2002 onward — represents substantial cleanup expenditures tied to releases that likely began well before those policies expired. Historical carriers who covered the dry cleaning and fuel storage operations during the pre-1986 window may bear obligations for costs already incurred.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
