Dry Cleaner cleanup site — Restorical Research

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 fund a cleanup — and recover costs already spent.

This property, enrolled in the Voluntary Cleanup Program, has tetrachloroethylene (PCE) confirmed in groundwater at concentrations slightly above the MTCA Method A cleanup level in the northeast corner of the site. Phase II investigations established the contamination, and the site is presently under a multi-quarter groundwater monitoring program required before a No Further Action determination can be issued. The proposed cleanup solution consists of institutional controls — a restrictive covenant, prohibition of drinking water wells, maintenance of an impermeable surface cap, and restrictions on future excavation activities. 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.

PCE contamination at this property is linked to pre-1986 operations: an abandoned underground storage tank documented on the site is characteristic of installations predating the federal regulatory standards that took effect circa 1986 and 1988, and PCE itself is a chlorinated solvent whose use as a dry cleaning agent substantially predates those standards. The costs already expended — Phase II investigations, multi-quarter groundwater monitoring, and sustained Voluntary Cleanup Program participation — represent documented remediation expenditures that historical CGL carriers who issued occurrence-based policies during the pre-1986 operational window may be obligated to recover. Those same carriers may also be called upon to fund the institutional controls and long-term monitoring still required to reach a No Further Action determination.

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.
