Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This Marysville property was operated as an industrial facility by Ollestad Plumbing & Sheet Metal, classified under construction and manufacturing. Contamination — identified as lead and heavy metals consistent with industrial operations — originated from a leaking underground storage tank and/or a spill at the site. A remedial action running from May 1993 through April 1997 likely involved excavation for tank removal and impacted soil, followed by environmental sampling to confirm cleanup effectiveness; the property was subsequently de-listed from the Hazardous Sites List and reached No Further Action status. 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 lead and heavy-metal contamination at this property is characteristic of industrial metalworking and plumbing operations — the kind of facility-linked release that occurrence-based Commercial General Liability policies written before 1986 were designed to cover, when pollution exclusions were either absent or narrowly construed. Documented remediation expenditures, including Ecology review fees and a reported minimum remediation outlay, reflect costs tied directly to those industrial activities. Historical carriers whose CGL policies were in force during the facility's operational years may still bear liability for the cleanup costs that were incurred to close this site.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
