Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1900. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was previously occupied by the Rainier Heat & Power Company Steam Heating Plant, which operated from the early 1900s through the late 1960s, storing Bunker C oil and diesel in two approximately 12,000-gallon underground storage tanks that were never decommissioned. The abandoned USTs were discovered during renovation of the Publix Hotel, which occupied the property from 1927 through 2002. Cleanup activities completed to date include debris and soil excavation, vacuum-truck groundwater pumping, and stormwater rerouting with sump installation; planned work includes formal UST decommissioning and backfilling, product removal, periodic pumping as an Interim Remedial Action, and long-term site characterization through monitoring well installation. 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 Rainier Heat & Power Company operated its steam heating plant at this address for roughly six decades, storing heavy industrial fuel in tanks that sat abandoned and unremediated long after operations ceased in the late 1960s. Carriers who issued occurrence-based CGL policies to the steam plant operators — or to subsequent property owners during the decades those tanks quietly leaked — may have coverage obligations that attach to the original release events rather than to the date of discovery during renovation. The documented cleanup costs here, from UST decommissioning and groundwater recovery to the long-term monitoring program now planned, represent expenditures those historical carriers 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.
