Industrial & Manufacturing cleanup site — Restorical Research
Sahlberg Equipment
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1955. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Seattle property operated as a construction and safety equipment wholesale and retail facility under Sahlberg Equipment, Inc. from the mid-1950s through 1993, with on-site machinery service, maintenance, and an equipment wash area throughout that period. Site operations also included an unpaved drum storage area where waste oil, anti-freeze, and solvents were handled. In 1993, a 300-gallon underground storage tank was removed and approximately 40 cubic yards of petroleum-impacted soil were excavated and disposed of offsite; monitoring well work was performed and quarterly groundwater monitoring was recommended as a continuing requirement. Cleanup work under the Standard Cleanup program is ongoing. 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 traces directly to equipment-washing and waste-fluid handling practices that were underway from at least the mid-1950s — more than three decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. An underground storage tank estimated to have been installed by 1967 or earlier further confirms that the contamination sources predate the modern pollution-exclusion era. Documented remediation costs — UST removal, soil excavation, monitoring well installation, and required long-term groundwater monitoring — represent expenditures tied to those pre-1986 operations that historical CGL 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.
