Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1928. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Shelton C Street Landfill operated as a municipal solid waste disposal facility from 1928 through its closure in 1984, serving the City of Shelton for more than five decades. Under an Agreed Order and a Remedial Investigation Work Plan, the City retained consultants to conduct multi-method geophysical surveys and soil sampling to characterize the extent and thickness of buried landfill waste and the infiltration of waste decomposition products. The site has since progressed to Construction Complete-Performance Monitoring status under the Voluntary Cleanup Program. 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 landfill accepted municipal solid waste — including materials containing DDT, which was broadly banned in the United States in 1972 — across more than five decades of operation that ended before the 1986 pollution-exclusion watershed. Occurrence-based CGL policies issued to the City of Shelton during those pre-1986 operational years had no effective pollution exclusion and remain enforceable today. The remediation construction that brought the site to its current monitoring phase, and the continuing performance-monitoring obligations ahead, represent costs that historical carriers who insured the landfill's operations 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.
