Auto Body cleanup site — Restorical Research
Shelton Yacht Club
Shelton, Mason County

Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup.

The Shelton Yacht Club facility operates as an active boat maintenance and repair site, hauling vessels out of the water for servicing and applying antifouling paint on-site. A Site Hazard Assessment and Initial Investigation Field Report have identified tributyltin (TBT) contamination resulting from those maintenance activities, and regulators have recommended the site be listed on a contaminated sites database. No active remediation — excavation, treatment systems, or cost-incurring cleanup — has yet commenced. 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.

Tributyltin antifouling paints were banned or heavily restricted for use on smaller vessels by 1988, and the July 1985 taxpayer-change record for Simpson Timber Company — the owner of the marine railway — places this facility in operation before that cutoff. Those two facts together make clear that the TBT contamination documented here originated from pre-1986 boat maintenance operations. The investigation and remediation costs now facing this property are liabilities that historical carriers whose policies covered the facility during that operational window may be obligated 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.
