Farm/Agriculture cleanup site — Restorical Research
Magnolia Fertilizer
Seattle, King County

Preliminary Site-Specific Analysis

This property has a documented history as a farm and agricultural operation going back to 1880. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as the Magnolia Milling Company — a feed grain and milling operation — from the 1880s through the 1950s, then transitioned to fertilizer manufacturing under the Magnolia Fertilizer name until operations ceased in 1981. Cleanup at the site included the removal of 81 drums of fertilizer material and floor sweepings in August 1990, followed by 17 drums of various liquid wastes in January 1991. The site has since received a No Further Action determination from Ecology. 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.

Fertilizer manufacturing and grain milling at this property spanned nearly a century of industrial activity, all of it prior to 1981 — more than five years before the 1986 threshold at which occurrence-based CGL policies began routinely excluding pollution claims. The drum removal and waste disposal work conducted in 1990 and 1991 to remediate that long-running industrial footprint represents documented cleanup expenditures tied directly to pre-1986 operations. Historical carriers whose policies covered the fertilizer manufacturing years may still bear liability for those remediation costs.

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.

What We Look For

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.
