Industrial & Manufacturing cleanup site — Restorical Research
American Crossarm & Conduit
Chehalis, Lewis County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1948. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This 14-acre property in Chehalis operated as a wood-treating facility from the early 1930s through 1983, with American Crossarm & Conduit conducting operations from 1948 onward, pressure-treating utility pole crossarms first with creosote and later with pentachlorophenol (PCP). Remediation has included excavation of 18,137 cubic yards of contaminated soil from the facility and an additional 2,500 cubic yards from neighboring residential lots, removal of floating oil from groundwater, incineration of contaminated materials, tank removal, sewer relining, well abandonment, and capping with clean soil under institutional controls. The site remains under active long-term operations and maintenance with regular Five-Year Reviews. 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.

Creosote and pentachlorophenol applications at this facility began decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The contamination here spread beyond the facility boundary into adjacent residential lots — a scale of off-site impact that reflects the liability exposure pre-1986 CGL carriers assumed when they insured industrial wood-treating operations of this kind. Historical carriers whose policies covered ACC's operations during that window may remain obligated to fund the ongoing remediation costs the site continues to generate.

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.
