Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal 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 Former Chevron Bulk Plant 61002620, a petroleum bulk storage and distribution facility with five aboveground storage tanks on its eastern half, until operations ceased in the early 1980s. Documented cleanup work includes removal of those storage tanks and associated structures, installation and development of purge and monitoring wells, granular activated carbon filtration of purge water, abandonment of soil borings, containerization of investigation-derived waste, and regular groundwater monitoring and site assessments conducted from at least 1994 through 2006. Cleanup is ongoing under the Standard Cleanup program. 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 property — TPH fractions, BTEX compounds, MTBE, and lead detected in groundwater — originated from bulk storage operations that ceased before 1986, when occurrence-based Commercial General Liability policies remained in force and carried no effective pollution exclusion. The presence of lead contamination is particularly significant: leaded gasoline was phased out of commerce in the mid-1980s, anchoring the contamination's origin squarely within the pre-1986 policy window. The site's documented remediation costs — AST demolition, purge well systems, activated carbon treatment, and more than a decade of groundwater monitoring — represent expenditures the 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.
