Public Works cleanup site — Restorical Research
WA National Guard Four Lakes
Fairchild Afb, Spokane County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property was originally constructed in 1951 as U.S. Army Nike Battery No. 37 and passed successively to the U.S. Air Force in 1961 and to the Washington Air National Guard in 1971. Hazardous materials were generated and disposed of on-site through vehicle maintenance, aerospace ground equipment maintenance, corrosion control, battery shop operations, and Nike Ajax missile maintenance. Cleanup included vacuum-truck removal of contaminated sediments, installation of an activated carbon treatment system at a nearby residential well, and injection of over 59,738 gallons of potassium permanganate for in situ chemical oxidation of groundwater between 2003 and 2005. The 2007 selected remedy — estimated at $195,000 — required relocation of a residential water supply well and recorded environmental covenants, and the site has since 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 contamination at this property — 1,1-dichloroethylene attributable to historical 1,1,1-trichloroethane use — originated from military operations conducted continuously from 1951 through the pre-1986 period under three successive government operators. Occurrence-based Commercial General Liability policies issued during those Army, Air Force, and Air National Guard operational windows had no effective pollution exclusion and remain potentially enforceable today. The documented remediation record — multi-year investigations spanning more than a decade, large-scale groundwater chemical oxidation, residential well treatment and relocation, and environmental covenants — represents the cost trail that recovery efforts against historical carriers would draw on.

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

  • 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.
