Landfill cleanup site — Restorical Research
Puyallup Landfill D
Puyallup, Pierce County

Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1963. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Puyallup Landfill D operated as a municipal solid waste landfill from 1963 to 1972, receiving waste placed below grade throughout that period. Cleanup activities under the Voluntary Cleanup Program have included installation and ongoing operation of a landfill gas control and extraction system — a 735-foot trench and blower system initiated in 2006 and 2007 — along with a 3-to-5-foot soil cover over the waste mass and shallow test pit excavations to delineate the waste boundary. Cleanup work 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 methane gas contamination at this site originates from municipal solid waste deposited between 1963 and 1972 — more than a decade before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. Operators who accepted waste or managed this facility during that window may have held CGL policies that attached at the time of each disposal event. The documented remediation costs here — gas extraction system installation, continued blower operation, waste delineation, and long-term 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.
