Dry Cleaner cleanup site — Restorical Research
Shelton Laundry & Cleaners
Shelton, Mason County

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1935. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Shelton Laundry & Cleaners has operated as a commercial laundry and dry cleaning facility since 1935, with tetrachloroethylene (PCE) used in its dry cleaning operations throughout that period. An unknown quantity of PCE dry cleaning solvent was reportedly spilled in an adjacent alley, and the facility has been identified as the source of reportable PCE and TCE concentrations in groundwater. Cleanup has included injection of a hydrogen release compound (HRC®) in June 2005 to stimulate in-situ biodegradation of chlorinated solvents, and long-term groundwater monitoring has been ongoing since 2002, continuing until cleanup levels are consistently achieved. 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 1935 — more than five decades before 1986, the year occurrence-based Commercial General Liability policies effectively stopped covering pollution claims. Carriers who issued CGL policies to Shelton Laundry & Cleaners during that half-century of pre-1986 operations had no effective pollution exclusion and may remain obligated under those historical policies. The documented remediation costs here — a 2005 bioremediation treatment program and over two decades of groundwater monitoring — represent both expenditures to recover and ongoing obligations that pre-1986 insurers may be required 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.
