Auto Body cleanup site — Restorical Research
H & H Diesel Service Inc 407 Arsenic Release
Milton, Pierce County

Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop going back to 1969. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This Milton property has operated as a diesel repair facility under the H&H Diesel name since the service garage was built in 1969, with contamination sources including a 500-gallon Stoddard Solvent underground storage tank and a cracked concrete waste oil storage vault. Cleanup under the Voluntary Cleanup Program included removal of the UST, excavation of 815 tons of petroleum-contaminated soil, and cleaning and filling of the waste oil vault. Ongoing remediation involves a Permeable Membrane Filter for bio-attenuation, placement of an asphalt cap, an Environmental Covenant implementing institutional controls, and multi-year groundwater monitoring with O&M inspections and a scheduled 5-year review. A proposed impermeable barrier was evaluated at costs up to $700,000 but was ultimately not implemented. 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 petroleum contamination at this site — from a Stoddard Solvent UST and a waste oil vault — originated from diesel repair operations established by 1969, more than a decade before 1986 when occurrence-based CGL policies ceased to reliably cover pollution claims. Environmental complaints and regulatory citations at the facility date to at least 1974, establishing that releases were occurring well within the coverage window of pre-1986 policies. The documented remediation costs here — UST removal, excavation of 815 tons of contaminated soil, ongoing bio-attenuation infrastructure, institutional controls, and a long-term monitoring program — represent expenditures that historical carriers may be obligated both to recover and to fund going forward.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
