Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1925. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as Pacific Coast Hemphill Oil Co's heating oil and coal distribution facility from 1925 to 1960, with both gasoline and heating oil underground storage tanks on site. In 1990, all four USTs — one gasoline and three heating oil — were removed along with petroleum-impacted soil, and four groundwater monitoring wells were installed. Environmental investigations and characterization were conducted from 1989 to 1992 and again from 2007 to 2008, with the site entering Washington's Voluntary Cleanup Program from 2008 to 2011. 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.

Petroleum contamination at this property traces directly to bulk distribution operations that ran from 1925 to 1960 — more than two decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The underground storage tanks removed in 1990 had been in service throughout that pre-1986 operational era, meaning the releases they caused originated well before modern policy language began excluding such claims. Historical CGL carriers whose policies covered Pacific Coast Hemphill Oil Co during that distribution window may be obligated to recover documented remediation expenditures and to fund any continuing cleanup obligations at this site.

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.
