Auto Body cleanup site — Restorical Research
Colstons Steam Cleaning
Auburn, King County

Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

The Colstons Steam Cleaning facility at 3409 C Street NE in Auburn operated as an automotive steam cleaning and degreasing operation, a use that historically involved petroleum oils, greases, and solvent-based cleaning compounds. Groundwater contamination at the site prompted Ecology involvement and the issuance of an Interim No Further Action letter in 1997, followed by multi-year groundwater monitoring conducted between 1997 and 2003. Satisfactory completion of that monitoring program led to the formal abandonment of monitoring wells and closure of active remediation obligations 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.

The groundwater contamination documented at this property is consistent with the slow, diffuse releases that result from years of automotive degreasing activity — the kind of ongoing occurrence that pre-1986 Commercial General Liability policies, written on an occurrence basis and without effective pollution exclusions, were structured to cover. The timeline here — significant enough contamination to require Ecology oversight and six years of groundwater monitoring, resolved under the VCP — points to operations and releases extending well before 1986. Historical carriers who issued CGL policies to the operators during that pre-1986 window may remain obligated to recover the investigation and monitoring costs incurred at this site.

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.

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.
