Public Works cleanup site — Restorical Research
USAF MAFB MTCA WP 64
Mcchord Afb, Pierce County

Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1946. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

McChord Air Force Base has operated as an active military installation since at least 1946, encompassing over 4,600 acres in Pierce County. Historical operations at the affected sub-sites include a Transportation Area (motor pool) and an aircraft washrack where planes were washed and drained of fuel. Cleanup under the Standard Cleanup program has included excavation of contaminated soils and drywells — removing 427 tons and an additional 11.27 tons and 10 cubic yards at separate areas — along with backfilling and paving of pits and ditches, implementation of institutional controls, and extended groundwater monitoring to track intrinsic bioremediation and natural attenuation. 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 contamination at McChord AFB traces to fuel-handling and maintenance operations — aircraft washracks, motor pools, drywells — that were active from the 1940s through at least the early 1980s, well before 1986 when occurrence-based CGL policies ceased to provide reliable pollution coverage. Multiple sub-sites (LF-01 operational from 1946, LF-02 through 1976, WP-61 from 1953 to 1960) document decades of pre-1986 activity that generated the contamination now subject to remediation. The documented scope of cleanup — multi-site soil excavation measured in hundreds of tons, ongoing groundwater monitoring, and permanent institutional controls — represents the kind of liability trail that historical carriers whose policies were in force during those operational decades may still be obligated to fund.

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.
