Public Works cleanup site — Restorical Research
Nisqually State Park Borrow Pit
update, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Nisqually State Park Borrow Pit was used as an informal shooting range on property owned and managed by Washington State Parks, with metals and carcinogenic PAH (cPAH) contamination identified in the borrow area soils as a result of that use. Documented cleanup work has included stripping contaminated soils from the borrow area, relocating those and other unsuitable soils to a recessed area beneath power lines, and grading them in place — with state funds already expended for that work. The site is recommended to continue cleanup through the Voluntary Cleanup Program and may require additional investigation before remediation is complete. 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.

Contamination at a shooting range accumulates through incremental deposition — each discharge adding lead shot and cPAH residues to the soil — a pattern of ongoing, repeated occurrence across whatever years the range was in active use. Washington State Parks, as a state agency operating recreational facilities, would have carried liability coverage during that period; if active use predates 1986, the carriers on those policies may remain obligated to contribute to the state funds already spent relocating contaminated soils and to the investigation and remediation costs the VCP process will require 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.
