Preliminary Site-Specific Analysis

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

This property was the location of Penthouse Draperies, a former dry cleaning operation that released tetrachloroethene (PCE) and its chlorinated daughter products into soil and groundwater. A separate release of petroleum hydrocarbons (TPH) from former underground storage tanks on or adjacent to the property was addressed through independent remedial actions, with groundwater monitoring conducted from at least 2001 through 2006 and a preliminary cleanup action plan prepared in 2003. As of January 2007, Ecology determined that further action for the PCE contamination in soil and groundwater remained required, rescinding an earlier No Further Action determination issued in 2002. The site currently holds No Further Action status. 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.

Contamination at this property traces to two distinct pre-1986 sources: a dry cleaning machine discharging PCE, and underground storage tanks that were already abandoned in place by the time a 1996 investigation documented nineteen of them — meaning installation and operation date well before 1986. Occurrence-based Commercial General Liability policies written for the operators of Penthouse Draperies and the associated UST facility during that era carried no effective pollution exclusion under Washington law. The remedial actions, multi-year groundwater monitoring, and regulatory process required to address releases from both sources represent costs that historical carriers whose policies were in force during those operations may be obligated to fund.

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.

What We Look For

  • Historical insurance policies (pre-1986)

  • Claims Management & Forensic Accounting

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.
