Dry Cleaner cleanup site — Restorical Research
SUNNYSIDE MUNICIPAL WELL
Sunnyside, Yakima County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1948. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Sunnyside Municipal Well No. 1 was contaminated with tetrachloroethylene (PCE) traced directly to the former Sullivans Dry Cleaners, which operated at the adjacent Speck property from 1948 to 1956 using PCE-based dry cleaning equipment. The contaminated municipal well was subsequently taken out of service as part of remedial response; five recovery wells were also installed to address a gasoline release at a nearby Texaco station. The original building was demolished in 1985 and the property later transitioned to use as a car dealership and body shop (Speck C. Motors), with investigations finding no current source of PCE contamination. Cleanup of the impacted groundwater plume is ongoing and has not reached completion. 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 PCE contamination at this site originated from dry cleaning operations conducted more than three decades before 1986, when occurrence-based Commercial General Liability policies still provided broad pollution coverage without effective exclusions. Sullivan's dry cleaning operations at this address from 1948 to 1956 fall squarely within that window, and the resulting contamination of a municipal water supply represents substantial remediation liability. Historical carriers who issued CGL policies covering those dry cleaning operations may be obligated to fund the outstanding cleanup costs.

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.
