Industrial & Manufacturing cleanup site — Restorical Research
Monroe Cold
Monroe, Snohomish County
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.

The Monroe Cold Storage facility operated as a cold storage warehouse and distribution hub, using diesel fuel for heating and receiving raw materials, processed vegetable supplies, and manufacturing supplies via an on-site railroad spur. A diesel pipe failure in 1990 triggered the initial contamination event; a dedicated hazardous materials storage shed on the property contained hydrochloric acid, lubricants, refrigeration oil, paint, stains, and pentachlorophenol. Cleanup under the Standard Cleanup program included the excavation and removal of 560 tons of petroleum-contaminated soil, removal of an underground storage tank, removal of the hazardous materials shed and its associated soil, and multi-year groundwater monitoring. The site has 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 diesel contamination here originated from an underground storage tank and heating system that were installed and in operation well before 1986 — the period when occurrence-based Commercial General Liability policies were the industry standard and provided no effective pollution exclusion. The hazardous materials stored on-site, including pentachlorophenol, were likewise present during that pre-1986 window, potentially implicating separate coverage obligations under policies issued to the facility's operators during those decades. Historical carriers whose CGL policies were in force when the UST and heating infrastructure were in operation may still be obligated to recover the documented remediation expenditures: 560 tons of excavated soil, tank and shed removals, and years of groundwater monitoring.

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

  • Historical insurance policies (pre-1986)

  • Evidence linking cleanup obligation to insured activity

What We Deliver

  • Historical Coverage Chart
  • Trigger Analysis & Property/Policy Nexus

  • Claims Management & Forensic Accounting

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.
