Industrial & Manufacturing cleanup site — Restorical Research
Independent Metals Plant 1
747 S Monroe St, Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1936. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The property at 747 S Monroe Street served residential use from 1936 through the early 1990s, during which period polychlorinated biphenyls (PCBs) accumulated on site. In 1991, Independent Metals Corporation began operating a scrap metal recycling business, accepting, sorting, and preparing non-ferrous metals such as copper, brass, and aluminum for recycling. Cleanup activities under the Voluntary Cleanup Program have included prompt cleanup of spills, waste recycling and disposal, upgrades to the stormwater collection and treatment system, and regular drainage and catch basin maintenance. The facility has also been identified as a Potentially Responsible Party for the Lower Duwamish Waterway Superfund Site. 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.

PCB contamination at this property is attributed to legacy accumulation during the residential period that began in 1936, placing the origin of contamination decades before 1986. The property's designation as a Potentially Responsible Party for the Lower Duwamish Waterway Superfund Site compounds the cost exposure beyond the site's own ongoing cleanup obligations under the Voluntary Cleanup Program. Historical carriers whose CGL policies were in effect during the years PCBs were accumulating at this location may bear responsibility for both past remediation expenditures and the Superfund-related liabilities still ahead.

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.
