Public Works cleanup site — Restorical Research
Shelton City of Boot Hill Property
Shelton, Mason County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The City of Shelton used this property for storage of construction debris and street sweeping waste accumulated over many years, and historically operated a wastewater treatment facility on the site that was demolished in 2010. Cleanup activities under the Voluntary Cleanup Program have been periodically ongoing since 2000, including decommissioning of an abandoned cistern and pumping approximately 7,000 gallons of contaminated liquid from a manhole. Planned remediation includes excavation and removal of 750 cubic yards of clean cover material and the disposal or on-site containment and capping of 3,500 cubic yards of contaminated street sweeping waste, with estimated costs for disposal and VCP fees ranging from $60,500 to $87,500. 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.

The contamination documented here — lead-bearing street sweeping waste stockpiled over a period of years predating 1986 — reflects municipal operations conducted during the era when occurrence-based CGL policies carried no effective pollution exclusion. Lead's presence in the accumulated waste is a marker of pre-1986 activity, as leaded gasoline was largely phased out by that year, and records confirm the waste had been accumulating for a number of years prior to the initial 2000 investigation. Historical carriers who issued liability coverage to the City of Shelton during that operational window may be obligated to fund both expenditures already incurred and the substantial remediation costs — waste excavation, disposal or capping, and long-term containment — still ahead for this site.

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.
