Pantorium Cleaners Shelton
Shelton, Mason County

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1976. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Pantorium Cleaners operated as a commercial dry cleaning facility at this Shelton location from at least 1976 until the business ceased operations in 2014, using tetrachloroethylene (PCE) and trichloroethene (TCE) as primary solvents throughout that period. Groundwater contamination was discovered in 2015 and attributed to those historical dry cleaning operations. Washington Ecology has designated a potentially liable person and is requiring a Remedial Investigation and Feasibility Study; no physical remediation work — excavation, groundwater treatment, or vapor extraction — has yet been performed at the site. 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 at least a decade before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The PCE and TCE contamination found in the groundwater here is precisely the kind of gradual, ongoing release those pre-1986 policies were written to cover. With a Remedial Investigation and Feasibility Study still ahead, the full cost of cleanup has not yet been established — and historical carriers who issued CGL policies during the pre-1986 operational window may be obligated to fund what comes next.

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.
