Heating Oil Tank cleanup site — Restorical Research
Battle Ground School District 119
Battle Ground, Clark County

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 operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The 650 Building at Battle Ground School District 119 was the location of three heating oil underground storage tanks removed in spring 1995, along with associated impacted soil. Groundwater monitoring has been underway since at least 1999, involving regular well purging and sampling. In-situ bioremediation using Oxygen Release Compound (ORC) socks — placed and replaced in monitoring wells to enhance subsurface treatment — is actively ongoing at the site. Cleanup remains in progress. 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 heating oil USTs at this property were in service well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Past remediation expenditures — tank removal, soil excavation, and more than two decades of groundwater monitoring — represent costs that historical carriers may be obligated to recover. Beyond those past costs, active in-situ bioremediation is continuing, leaving future remediation expenditures open; carriers whose policies covered the pre-1986 operational period may face liability for those forward-looking costs as well.

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.
