Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1987. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

The ELDEC North Creek Facility operated as a circuit board manufacturer for the aerospace industry from 1987 through 2005, using solvents, lead, and cyanide in its manufacturing processes. Site records also document removed fuel pumps and 500-gallon underground storage tanks on the property. A groundwater investigation and monitoring project conducted in 2005–2006 examined chemicals associated with the circuit board manufacturing operations, and the site received a No Further Action determination 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.

Underground storage tanks at this property were removed before the 2005 investigation, indicating fuel-handling infrastructure that may have been in service before 1986 — when occurrence-based CGL policies were still standard and lacked effective pollution exclusions in Washington. The solvents, lead, and cyanide used in ELDEC's circuit board manufacturing from 1987 through 2005 add a second dimension to the site's contamination profile. Historical carriers who provided CGL coverage during the operational period of those tanks may bear obligations for the investigation and remediation expenditures this property has incurred.

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)
  • Policy numbers, carrier names, and coverage periods
  • Connection between contamination timing and policy period
  • Evidence linking cleanup obligation to insured activity

What We Deliver

  • Historical Coverage Chart
  • Trigger Analysis & Property/Policy Nexus
  • Coverage strategy with recommendations
  • Insurance funding for your remediation
  • 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.
