Gas Station cleanup site — Restorical Research
EXXON 77135
Everett, Snohomish County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as Exxon Station 77135, a gasoline service station with multiple underground storage tanks and dispenser islands that have since been removed. Remediation has included in-situ chemical oxidation injections using 605 pounds of PersulfOx™ and 432 gallons of water, along with Soil Vapor Extraction and Air Sparge systems, with groundwater monitoring and sampling conducted continuously since at least 1992. The former station footprint is currently occupied by an operating espresso stand and a telecommunications company, and cleanup work is ongoing. 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 originated from underground storage tanks whose operation and documented leakage trace to well before 1986 — the year after which occurrence-based Commercial General Liability policies began routinely excluding pollution claims. The remediation record here is substantial: UST and dispenser island removals, chemical oxidation treatment, vapor extraction infrastructure, and more than three decades of groundwater monitoring, all expenditures tied directly to pre-1986 fueling operations. Historical carriers who issued CGL policies to Exxon or its station operators during that window may be obligated to recover those past costs and to fund the remediation work that continues today.

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.
