Heating Oil Tank cleanup site — Restorical Research
Philpot
Camas, Clark County
Restorical Research
Preliminary Site-Specific Analysis

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

This residential property in Camas contained a 675-gallon gasoline underground storage tank and a 300-gallon heating oil tank, both bare steel with no corrosion protection. In August 2016, both tanks were removed; the heating oil tank was found to have corroded holes through the bottom, identified as the contamination source. An initial investigation and an Ecology Early Notice Letter in 2018 confirmed that groundwater beneath the property is suspected to be contaminated with petroleum diesel and petroleum gasoline above MTCA cleanup levels. The site is enrolled in Ecology's Standard Cleanup program with remediation underway. 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.

Both tanks at this property were bare steel construction with no cathodic protection, fiberglass coating, or double-wall design — a standard that predates the 1988 federal UST regulations and is characteristic of pre-1986 installations. The heating oil tank's advanced corrosion, with holes through the bottom consistent with decades of underground use, further supports a long operational history reaching into the occurrence-based CGL policy era. The cleanup costs now being incurred — investigation, remediation of petroleum-contaminated groundwater — represent liabilities that historical carriers who issued policies during that pre-1986 operational window may be obligated to fund.

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.
